I would definitely expect periodic transactions to accept date ranges.

Re: Forecasting beginning in the future

[Bob Wilson]

I'm having the same issue.

Example file:
~ Monthly from 2024/02/15
Expenses:Rent  $500.00
Assets

Command:
$ ledger -f test.dat --forecast "d<[2025]" register Expenses:Rent

Update example file:
~ Monthly from 2024/04/15
Expenses:Rent  $500.00
Assets

Same command gives empty output.

The other thing I'm noticing is the periodic expressions don't respect 
exact dates. If my rent is due on the 15th, and my period expression 
denotes that, I'd expect the forecasted transactions to be on the 15th.

Total posting costs and precision issues?

[Bob Wilson]

Hi folks,
   I have some stock purchases that I have specified using total costs. 
Because of not-round-numbers, I'm having trouble specifying the lot so I 
can sell it cleanly.

Here's an example:

2023/11/01 * Buy Shares
Assets:401K 6.456 FSKAX @@ $734.43
Income:Opening Balances  -$734.43

2023/11/02 * Sell Shares
Assets:401K-6.456 FSKAX {$113.7592936803} 
[2023/11/01] @ $120.00
Income:Capital Gains  -$40.29
Assets:401K   $774.72

The first transaction uses the total posting cost. To record the second 
transaction, I ran, `ledger --lots balance Assets:401K`. I copied that $113 
number verbatim as printed.

So I've sold all the shares, but now when I run `ledger --lots balance 
Assets:401K`, the result is:

 $774.72
6.456 FSKAX {$113.7592936803} [2023/11/01]
-6.456 FSKAX {$113.7592936803} [2023/11/01]  Assets:401K

So it looks like the lot I sold doesn't quite match what ledger thinks I 
owned. I anticipate the issue is that the precision used in printing is 
different than the precision used to store lots internally.

I tried selling using the total posting cost:

2023/11/02 * Sell Shares
Assets:401K-6.456 FSKAX {{$734.43}} 
[2023/11/01] @ $120.00
Income:Capital Gains  -$40.29
Assets:401K   $774.72

That works great as long as I sell whole lots. But as soon as I try to sell 
a partial lot, it doesn't work at all. (The capital gains are not 
calculated correctly.)

The best idea I have right now is to just not use total posting costs, and 
always use the per-share price. But I find total posting costs to be 
convenient for many use cases.

Any suggestions?

Thanks folks!
Bob Wilson

Re: Printing to stdout

[Bob Wilson]

--no-pager works. Terminology in hand, the guide suggested looking at the 
LEDGER_PAGER environment variable, which is unset on my platform.

I installed via homebrew (I'm on macos 13.4). Perhaps some detail on how 
they compiled ledger is relevant?

Printing to stdout

[Bob Wilson]

Hi folks,
   I recently upgraded to Ledger 3.3.2-20230330, from 3.2.1-20200518.

Previously, running a command like `ledger -f ledger.dat balance ^Assets` 
would print results directly to the screen and return me to the prompt, but 
now that same command prints results to some kind of temporary screen that 
disappears when I hit `q`. It's like the difference between `cat` and 
`less`. Sorry I don't know the right terminology!

As a workaround, I can pipe the command into cat, and then it prints to the 
screen. Is there a way to just print to the screen by default?

Thanks!
Bob Wilson

[Elecraft] N6TV Product Announcement - new "K-ON" plugin for K3, K3S, and K4

[Bob Wilson, N6TV]

Thanks to circuit design help from K9JB, and after review by Elecraft Chief
Engineer, N6KR, I'm now able to provide a new plugin module for
the Elecraft K3 and K4 that I call the "K-ON".

When connected to the rig's ACC jack directly, or via a 15-pin Y-cable or
Y-BOX , the rig will automatically power up whenever
the rig's DC power supply powers up.  This could be useful to remote
stations with Internet-accessible AC power strips.  I also find it useful
at my home station where I use a "Master Power On" switch that powers
everything up automatically, including two K4Ds.

If you already have a Y-BOX with an unused connector, the K-ON plugs right
in.  I'm also including the same circuit inside the new Y-BOX v4.0 (so the
plugin is not needed).  The "Auto On" feature of Y-BOX v4.0 can be enabled
or disabled by a shortened RCA plug, as shown in the third demo video on
the website.

For photos, demo videos, and ordering one or more K-ON plugins, please
visit the new website.

https://bit.ly/N6TV-KON

Unlike some solutions that have previously been suggested, such as
connecting a big capacitor to ACC Pin 8, connecting the K-ON plugin has no
surprise side effects.  The rig's POWER switch and PS0; commands continue
to function normally, so the rig shuts down properly while the module
remains connected, as shown in the videos.  You can still connect a
RemoteRig box in parallel with no issues either; it will still function
normally.

Bob, N6TV

Re: Compound interest and amortization

[Bob Wilson]

Hi Viraj,
   (I recently joined the Google group and discovered your post. Hope my 
comment is still useful!)

I have a hacky way of doing this with automatic transactions. Weird 
context: I use "4x entry accounting". A typical transaction involves two 
virtual entries and two real entries, like:

2023/05/01 * Starbucks
[Funds:Food]-$5.00
[Assets:Checking]$5.00
Assets:Checking -$5.00
Expenses:Food$5.00

The idea is that in one sense, all of my money is in Funds, and has to be 
transferred to some account in order to spend it. This is my implementation 
of "envelopes" from You Need A Budget.

That context is irrelevant to your question, but explains some of the 
syntax that follows.

I'll use my 401k as an example. The money in my 401k is in a Fund (which I 
label as a Goal so I can do goal tracking). I have a bunch of entries that 
look like:

2024/01/01
[Goals:Retirement]   = $0.00
[Income:Interest:Placeholder]

2025/01/01
[Goals:Retirement]   = $0.00
[Income:Interest:Placeholder]

One transaction per year, going until my planned retirement year. These 
basically say, take all the money out of the Goal account, and relabel it 
as Income. I put a Placeholder tag on the income to avoid mixing this up 
with real interest.

Then I have an automatic transaction:
;; Retirement forecasts with interest calculations
= /Income:Interest:Placeholder/
[$account]   -1.0
[Goals:Retirement]1.0
Income:Interest:Account -0.06
Assets:Investments:Retirement0.06
[Assets:Investments:Retirement] -0.06
[Goals:Retirement]   0.06

The idea here, is that in the first tx, I moved all the money in the 
account to an Income category, so now the automated tx "knows" how much 
money is in the account. Then I put the money back in the Goal account in 
the first two lines of the automated tx. Then I take that amount and 
multiply by my predicted return, 6%. (Is that overly ambitious? Idk, put 
whatever number there you want.) Then I take that return and add it to the 
account.

As I said, it's hacky, but it works!

Re: [Elecraft] Y-Box connections KPA500/K3

[Bob Wilson, N6TV]

Sorry Josep, the Y-BOX is designed to connect the ACC connector of one K3
or K4 to multiple devices, such as one amplifier and one automatic antenna
switch or bandpass filter box; it cannot be used to connect two K3s in
parallel to one amplifier.  It *might* work if one K3 is completely powered
off, but why bother?  Changing bands with one K3 and one KPA500 from N1MM
is very quick; no advantage to having two K3 radios unless you configure an
SO2R station.

Re: [Elecraft] FS - N6TV Y-Box

[Bob Wilson, N6TV]

I don't remember what Ed had connected to his Y-BOX.  Maybe just an
Elecraft amplifier and an FSK keyer like a Mortty or WinKey V3.

Unlike the K3, the K4 provides two (2) independent virtual serial ports via
the USB cable, plus a third independent legacy RS232 port, all of which now
support FSK RTTY keying directly via DTR pin, with no external keyer device
required.  So, the K3 requirement to break out the FSK pin of the ACC to do
FSK RTTY keying no longer exists with the K4, though it's still supported.
You no longer need to use external devices to get FSK RTTY keying from
MMTTY.  See the Elecraft K4 Application Note

.

The Y-BOX is still very useful with a K4, if you want to connect more than
one device to the K4 ACC connector, such as an automatic amplifier and an
automatic antenna switch / band decoder, plus a Mortty or WinKey V3 for
external FSK keying, or a RemoteRig box for Remote Power ON, or a microHAM
keying interface.

Version 3.0 of the Y-BOX now includes four pull-up resistors to 12V on the
band data lines, which is only required when connecting certain
combinations of equipment to either the K3 or K4 in parallel, such as a
KPA500 and an Antenna Genius or BCD-14 Band Decoder, due to the
opto-isolators in some non-Elecraft devices draining too much current from
the pins.  The Y-BOX also provides an option to remotely toggle an Elecraft
amplifier on or off from a K3 or K4 macro button, which is not supported by
the Elecraft AUX cable without modification (because the Elecraft KPAK3AUX
cable has no connection to Pin 8, so it provides no access to the KPA
remote PWR ON line).  The Y-BOX replaces the Elecraft AUX cables with
standard 15-pin cables and is available in various lengths.

Yes, though it doesn't matter (electrically) which device connects with the
Elecraft AUX cable.You could plug the extension into the Y-BOX and the
AUX cable into the amp.  FYI, the correct term is DE15 (sometimes HD15 for

If it's 5 ft long, that adds to the total length between K3 and AMP and
RCS-12 controller.  If you don't need 5 ft between rig and Y-BOX, replacing
it with a 2.5 ft cable will reduce the  the total length (and loss) by a
little bit.  But it will probably won't make any difference.

The K3 will automatically memorize and recall the required drive level set
on each band, but not each band segment, if you set K3 *MENU:PWR SET* to *PER
BAND*.  The K3 remembers two drive levels per band, one "barefoot", and the
other "when the AMP is ON and in OPER".  So you can leave the K3 set to
100W drive, then turn on the AMP and put it in OPER mode (you'll see a
message on the K3 when you do that, if connected properly), then turn down
the PWR knob to set the drive level needed on that band when you're using
the amp.  An asterisk appears next to the power level on the K3 display, to
indicate that you are setting the "when the amp. is in OPER" power level.
The asterisk goes away when you put the amp. in STBY or OFF.  Set the drive
needed once, each band, with the amp. in OPER mode, and and you're all set;
the K3 will set the drive power to the last-used values for amp in OPER
mode, on every band.

The KPA1500 tuner is set by band *segment*, but not the drive power.

40m SSB is a problem child for me where a short Yagi means I have to cut

The K3 will not remember that.  How high is the SWR up there?  I assume you
are using the KPA1500 ATU, but if SWR is >3:1, I don't think you can run
1500W even with the tuner engaged.

Yes, you will get that by extending the AUX cable, which must be in series
with the extension.  I would try the length you need to see if it works.
Chances are it will work fine if you use a quality cable.

Should work fine.  I can supply a 2.5' M/M cable from rig to Y-BOX if you
need one.

Great, then you only need one 15-pin cable or one new Ethernet run, not two.

Re: [Elecraft] Relocating my KPA-1500 - need cable

[Bob Wilson, N6TV]

I would try the 25' to 30' AUX cable.  It will probably work fine.  AUXBUS
is only used for automatically setting drive power ("KPA1500 OPER"
messages) and recognizing band buttons being pressed on the amp, which you
will not be doing, plus rig frequency setting the KPA1500 tuner to the
right segment, though RF-sensing can work for that too.  If you don't use
the tuner much, or If AUXBUS gives trouble, change radio type from K4 to
BCD, and use the same long AUX cable.  If that doesn't work, a long RS-232
to 3.5mm TRS cable can be used to track K4 frequency.

A long ethernet or a WiFi to Ethernet extender will provide KPA1500 Remote
software connection capability, though you may want to set up your Router
to assign a fixed IP address to the KPA1500.  KPA1500 Firmware updates
still require a local USB cable, but you can temporarily use a WiFi-enabled
laptop for that.

Re: [Elecraft] Relocating my KPA-1500 - need cable

[Bob Wilson, N6TV]

Peter,

My records show that you purchased the original Y-BOX v1.3, which requires
an Elecraft AUX cable from Y-BOX to amp.  (The Y-BOX v2.x and v3.0 Y-BOXs
allow any DE-15 M/F non-VGA cable to be used instead of the Elecraft AUX
cable).

The easiest solution, if your electrician can snake a cable with the molded
DE15 connectors through the wall, is to insert a 25' M/F 15-pin extension
cable like this one *in series with your AMP AUX cable*.

https://cablesondemand.com/15-pin-hd-d-sub-cable-hd15/15-pin-hd15-deluxe-hd-d-sub-cable-copper-shielded-male-female-cs-dsdhd15mf0-025

This will achieve the proper electrical connections, though at 31' total
length you may be at the limit of the maximum AUX cable length that will
work reliably.

Another option is to have your Electrician wire a pair of SHIELDED
"Ethernet" CAT6 (8-wire) outlets between shack and basement, with RJ-45
jacks mounted to the wall.  Wiring two pairs of outlets at each end will
allow both Elecraft AUX *and *Ethernet connections to the amp from
upstairs, providing a good connection for the KPA1500 Remote software
running on a PC upstairs.  But, KPA1500 firmware updates (rare these days)
will still require a direct USB connection to the amp.

If using RJ-45 jacks (something Electricians regularly install), I can make
you a custom DE15M to RJ45 shielded cable to reach from Y-BOX to the wall
jack, and a second RJ45 to DE15F cable from basement wall jack to the AMP
AUX.  Only 8 pins out of the 15 will be connected, but that will be
sufficient.  I could theoretically make a USB to RJ45 cable that would
allow USB connection to the amp. for firmware updates, but the theoretical
maximum length if USB 2.0 is about 15', so that may not work well at all.

Re: [Elecraft] K3 auto transmit - W7RIP

[Bob Wilson, N6TV]

If you disabled Serial Enumeration and Modem Control at Startup, as shown
by screenshots in this document:

https://bit.ly/FTDItip

but the rig still keys when you connect the USB cable or turn on the PC,
then you may need to do it again, especially if the cable was moved to a
different USB port and Windows assigned a new serial port number, or a
Windows Update updated the FTDI device driver.

Also, uninstall any CyberPower Home UPS control software, which scans all
serial ports looking for a UPS, every time the PC boots, and this will also
key the rig, assuming CONFIG:PTT-KEY is set to RTS-DTR to enable
computer-generated CW and PTT keying.  If not, set it to OFF-OFF

Re: [Elecraft] When is a Key Out not a Key Out

[Bob Wilson, N6TV]

Elecraft and ACOM amplifiers have a jack labeled KEY IN, so connecting KEY
OUT to KEY IN makes the most sense.  Alpha and SPE amps call it a RELAY
jack, but most rigs and some QSK amps don't use actual T/R relays any
more.  A few amps have a jack labeled PTT (RF Kit, Juma).  If you connect a
PTT jack on a rig to the PTT jack on these amps, obviously that won't work
unless both are wired in parallel to a footswitch or PTT circuit to key
both simultaneously, but then you can't use VOX.

Yaesu rigs key amps using a jack labeled TX-GND.  Icom labels it SEND.
Kenwood rigs use a RL pin on a DIN plug labeled REMOTE.  KEY OUT makes much
more sense than any of these labels IMHO.

Any jack on a *rig* labeled PTT is an input, not an output.  I can't think
of any modern rig that has a jack labeled "PTT OUT".

Check again, because that does not match my experience if your K-POD
firmware is at 1.09 (can't test now, sold both K3s).  If CONFIG:VFO CTS is
set to 100 (or 200?), I'm pretty sure the K-POD knob tunes at the same rate
as the VFO A knob.  I don't think a power cycle is required.

If Elecraft could do it, I'd like for the K3/K3S F/W to provide the option

Yes, we asked for that years ago, but it never happened, and I don't think
it will ever happen.  There's just no room left in the K3's limited memory
to add such complex code now.

Consider upgrading from the K3 to a K4.  K-POD plugs straight in via USB
cable and works perfectly.

Re: [Elecraft] Elecraft K-Pod manual updated -- now covers use with the K4

[Bob Wilson, N6TV]

In the K3, if you change *CONFIG:VFO CTS*, the VFO frequency moves faster
at 400 than at 100 (counts per turn), but the K-POD always tunes at 100 or
200 counts per turn (can't remember which).  The K-POD ignores the VFO CTS
setting on a K3.

In the K4, the equivalent setting is *MENU:VFO Counts per Turn*, and *both*
the VFO knob and the K-POD tuning rates are affected equally.

Just spin one knob exactly one full 360° turn clockwise, then spin the
other knob full turn counterclockwise.  If you don't end up back on the
frequency where you started, it means the tuning rates are not the same.

Yes, this only works with the K4.  The K3 firmware cannot reprogram the

You do not have to tap the on-screen keyboard to enter macro text into the
K4.  The K4's built-in Macro Editor supports ten finger typing with a real
USB keyboard plugged into one of the K4's three standard USB Type A
connectors.

An external USB keyboard is currently the easiest way to enter long macro
strings into the K4.  Hopefully someday Elecraft will provide a new host
command to store macro text.  Such commands would allow PC software, or
basic batch files, to save macro text into the K4.

I guess you're referring to this thread:
https://groups.io/g/Elecraft-KX/topic/86464063#70583

Cyclic macro technique for KX2 or KX3 was described 8 years ago in this
post:

https://groups.io/g/Elecraft-KX/message/37876

Sorry, but I don't see any way to use that technique with the KPA1500,
because holding or tapping PF keys doesn't reprogram them, and there is no
command to scroll to a specific menu item.

You can program a PF key to reprogram itself after it runs, but I see no
way for it to cycle between the five different min fan speed commands ^FC0;
.. ^FC5;

But, you can use the K3 Utility to program PF1 to set FAN SPEED MIN to 0
(used for normal operating), and PF2 to set FAN SPEED MIN to 1 (for
contesting), say.

   1. Open the KPA1500 Utility and Connect to the K4
   2. Go to the *Command Tester* tab
   3. Click the *Edit Macros* button.  Copy paste these two macros exactly
   as shown to program PF1 and PF2 to display message text and set the minimum
   fan speed:

   Macro Label   Macro Commands
   PF1=FAN0  ^PF1^DTFan Speed Min 0,^FC0;
   PF2=FAN1  ^PF2^DTFan Speed Min 1,^FC1;

   4. Click *Save*
   5. Click the *PF1=FAN0* and *PF2=FAN1* buttons *once *in the *Command
   Tester* tab to program the two PF keys
   6. Now you can just hold PF1 or PF2 to select between the two different
   minimum fan speeds

If you just want to hear what the different fan speeds sound like, tap
MENU, scroll down to FAN SPEED MIN, hold EDIT, and tap the up and down
arrows.  Speed 5 is louder than a vacuum cleaner.

Re: [Elecraft] VGA cable to Elecraft amps

[Bob Wilson, N6TV]

That's almost right.   You cannot use a VGA cable with the Y-BOX or any
Elecraft radio because they almost always short too many pins to ground.or
to each other.

A straight 15 pin M/F (non-VGA) extension would have worked OK to extend
the Elecraft ACC cable.  I supply these with the Y-BOX.  I can also obtain
longer lengths.  The Y-BOX transforms standard 15-pin straight cables (not
VGA) to KPAK3AUX equivalent, plus some extras like powering on the amp.
from a K3 or K4 macro, or optionally opening the keying line so that an
external device like a SteppIR controller can protect itself from high
power while it is moving.  The "Key Line Interrupt"  gender changer
supplied with the KPAK3AUX cables is not needed with the Y-BOX since that's
built into the Y-BOX as a jumper option.

Re: [Elecraft] New K4 beta software available release 22

[Bob Wilson, N6TV]

This will happen if K4 ACC Pin 8 (PWR ON) is being held to ground by
incorrect cabling to external devices.

Disconnect any cable from K4 ACC and the rig should power on and off and
reboot itself properly.

With proper cabling, no such disconnect is required to update the K4
firmware.

Skip et al,

No one can answer this question, unfortunately, because Elecraft's
suppliers can't answer Elecraft's questions.  The world-wide chip shortage
(and other factors beyond Elecraft's control) make providing reasonable
delivery estimates nearly impossible.  This applies to many products
including autos, not just the K4.

Most Elecraft K4 discussion is taking place on an independent moderated
mailing list with almost 1,000 members:
https://groups.io/g/Elecraft-K4/topics.  I cannot read this Elecraft
mailman reflector regularly because I'm spending most of my time in that
dedicated K4 group, not here.  You can search the group for answers to
common questions, such as K4 Remote support (still under development).

*K4 shipping status and delivery questions should be posted to separate
dedicated groups* that are trying to estimate Elecraft's ship rate based on
serial numbers and public reports.

https://groups.io/g/CreativeK4ShippingStatus/topics

https://groups.io/g/Elecraft-K4DeliveryInformation/topics

And of course the official Elecraft page is here:

https://elecraft.com/pages/shipping-status

Note that "Group 1 K4D June 24th" means  June 24th, *2019*.

Re: [Elecraft] K4 Key Out spec

[Bob Wilson, N6TV]

Though not in the K4 manuals, the K4 KEY OUT jack (an RCA phono connector)
has the same specs as the K3 KEY OUT jack: capable of keying up to +200VDC
@ 5A.  The K4 uses the same MOSFET as the K3, an IRFI630 (see datasheet
).

Note that the *other* key out line, PIN 8 on the ACC connector, is rated
for 10 mA max, which is also the same as the K3.  If you want to know how
much current  your amplifier KEY IN (relay) jack requires,  short an
ammeter across the KEY IN jack, negative lead to ground.  This should key
the amplifier relay, and then you can read the current.  Usually it's way
under 10 ma.

Re: [Elecraft] A Clarification: IC-7300 vs FTDX10

Neither the KPA500 nor the KAT500 can auto-track the frequency any Icom rig
by itself.  Instead, go for the KPA1500 with its built-in tuner, which
auto-tracks *all* Icom rigs via it's 2-wire REMOTE (CI-V) connector quite
perfectly.

The KPA500 XCVR serial port and KAT500 PC DATA port are completely
compatible with Kenwood's serial ports for auto-track, but the KPA500 XCVR
interface is NOT compatible with Yaesu rigs, because Yaesu's frequency
commands don't match the Kenwood standard properly (not enough leading
zeroes, something Elecraft may be able to handle some day with a firmware
update to both the KAT500 and KPA500).

The KPA1500, on the other hand, WILL auto-track any modern Yaesu rig via
serial port just fine.  My Serial Box  can help with
the interconnections to both using stock molded cables, so no homebrew or
expensive custom cables are needed.

Though you can wire the LINEAR connector of a Yaesu rig to a KPA500 AUX
connector, and it will auto-track band changes perfectly, the KAT500 will
not track the VFO frequency, so it's only half of what you requested.

So in sum, if you're looking at any Icom or Yaesu rig, consider the KPA1500
instead of the KPA500/KAT500 combo, or wait for new firmware to support
Yaesu's frequency format.

Icom support in the KAT500/KPA500 is not possible, only the KPA1500 has the
hardware.

Another option to consider is N4PY's Pegasus Plus
 software, which will translate Icom
and Yaesu frequency data to Kenwood format for the KPA500 and KAT500.  The
S-BOX-USB can be configured as a null-modem cable interface to connect
N4PY's software to both the KPA500 and KAT500 using a single USB port on
the PC.

[Elecraft] Warning: Windows 10 Update resets FTDI options back to defaults, keys radio

[Bob Wilson, N6TV]

I just installed a Windows 10 Update, and even before rebooting to complete
the install, I noticed that Windows had reset all my Elecraft FTDI virtual
COM port settings back to the (bad) FTDI defaults, which means your PC can
key your radio about 7 or 8 times every time Windows restarts  or the USB
cable is connected, assuming *CONFIG:PTT-KEY* is set to *RTS-DTR* in a K3,
or *MENU:Serial, USB-PC1* or* USB-PC2 DTR/RTS* is set to *CW* or *PTT* in a
K4, to support computer-generated CW and PTT.

To prevent this unwanted radio keying by Windows, while still being able to
use computer-generated CW and PTT on these COM port pins, do this for every
FTDI port:

   1. Open Windows Device Manager
   2. Expand *Ports* section
   3. Right click on Elecraft virtual COM port(s)
   4. *Properties*
   5. *Port Settings* tab
   6. *Advanced* Button
   7. Make sure *Serial Enumerator* is NOT checked
   8. Make sure *Disable Modem Ctrl At Startup* *is checked*
   9. Click *OK*

More details with screenshots in this updated presentation linked from my
QRZ.COM page :

   - Everything You Need to Know About USB and Serial Interfaces
   , updated for 2021

See slides 26, 27, and 28.

I've just updated this presentation (today) with a few new slides showing
on how to avoid the same unwanted keying issue when using legacy serial
ports like COM1: and COM2: (slides 29 to 33), and one new K4 Menu
screenshot (slide 52).

Re: [Elecraft] Giving Up

[Bob Wilson, N6TV]

Doug,

You didn't mention what rig you are going to buy instead.  Be sure to be
aware of its limitations before you buy it.

For example, the FTdx101MP has three show-stoppers (for a CW op like me),
despite it's impressive numbers in the Sherwood table:

   - Poor QSK performance (the clicking keying relay cannot be disabled,
   same problem as the IC-7300)
   - No CW sidetone output on USB Audio CODEC-- cannot record both ends of
   your QSOs (a contest requirement in some contests)
   - Mouse wheel is not supported for fine tuning or RIT (I think).  K4
   supports this very well

As for comparing the K4 to the K3, despite the K3's "superior" numbers in
the Sherwood table, the K4 SOUNDS so much better than any K3.  The K4 audio
is just SO CLEAN compared to the K3, which makes a big difference when a
pileup calls.  That quality is not captured by any subjective measurement.
The narrow DSP filters (down to 50 Hz) also seem to work so much better in
the K4 than the narrow 250 or 200 Hz crystal filters in the K3 -- no
ringing.

Re: [Elecraft] Receiving with Skimmer SDR on K-3 transmit antennas

[Bob Wilson, N6TV]

I documented the procedure about 13 years ago in this presentation, linked
at the very bottom of my QRZ.COM page , which
includes the recommended Mini-Circuits 50 ohm splitter (ZFSC-2-6
).

   - Adding a Software Defined Radio (SDR) to an SO2R station
   

High power cannot exit the RF ANT OUT jack, so it's safe, but there's no
way to prevent a local skimmer from spotting you.  Skimmer won't spot your
own call, but it will usually spot busted variants.  I recommend
disconnecting your skimmer from the RBN when operating at the same site.

Local RF will usually leak into the SDR even with no antenna connected; the
SDR is very sensitive.  Probably no way to mute it completely during TX.

What is "Jack 13?"  Do you mean the REMOTE (CI-V) jack on the IC-7610 (a
3.5mm phono connector), or the REM jack on the KPA1500 (RCA), which is only
used for remote power ON, and you probably should not have anything

The most common cause is to plug the Icom CI-V cable into the KPA1500 TUNE
jack (the bottom one) instead of into the XCVR SERIAL jack (the top one).

The KPA1500 REM jack is only used to power on the amp. remotely.  It is
*not* a CI-V connection to the REMOTE jack on the IC-7610.

Incorrect cabling or KPA1500 RADIO menu and BAUD rate not set to match CI-V
Baud Rate in radio.

If you recently updated the IC-7610 firmware, but did not save and restore
your menu settings then everything has been reset back to Icom factory
defaults in the IC-7610.

In the IC-7610 *SET > Connectors -> CI-V* menu:

Set *CI-V USB Port* to *Unlink from [REMOTE]*
Set *CI-V Baud Rate* to *19200*  (do not use *AUTO*.  Do not confuse this
setting with *CI-V USB Baud Rate* which is a completely independent for the
USB cable)
Set *CI-V Output (for ANT)* to *ON*


In KPA1500 Menu:

Set *RADIO TYPE* to *ICOM*
Set *RADIO POLL* to *OFF*
Set *SERIAL SPEED XCVR* to *19200*

Re: [Elecraft] Share a port for KPA500

[Bob Wilson, N6TV]

I designed the S-BOX for just this type of serial port sharing.  It passes
all serial lines straight through from PC (normally) to Radio RS232, and
taps the RXD line (Pin 2) for the KPA500, KAT500, SteppIR, etc.   This
works with POLL OFF as long as a logging program is polling the radio
properly.  It also works in series with the K3S + CBL3PY + P3.

The S-BOX can just as easily be inserted as a null modem cable + tap
between TS-890S and TS-590S (and as a Y-cable to the KPA500, with TS-890S
Pin 2 connected to KPA500 XCVR SERIAL Pin 2).

So, it should work to connect the serial connector of the TS-890S to the
TS-590S with a tap, but as you say, if Kenwood only supports that
master/slave connection at 115200 baud, as stated in the Kenwood manuals,
then neither the KPA500 or KAT500 will be able to track, since they both
max out at 38400.  FYI, the KPA1500 XCVR SERIAL connector supports all
common baud rates from 4800 to 230,400 baud, but the KPA500 does not.

Re: [Elecraft] KPA500-KAT500 tuning settings

[Bob Wilson, N6TV]

Andy,

Kenwood rigs have master/slave menu options designed to enable one Kenwood
rig to follow the frequency of another.  The KAT500 manual recommends
enabling these options, but I cannot confirm if they affect the frequency
reported by the FA; command.  If you have a null modem cable, can you
please connect it to the TS-590 COM port when these options are enabled,
and report what gets output when SPLIT is ON?

TS-590S:

Set *Menu 58* TRANSFER SPLIT FREQUENCY DATA TO ANOTHER TRANSCEIVER to *ON*
Set *Menu 59* COPY SPLIT FREQUENCY DATA TO VFO to *ON*


TS-590SG:

Set *Menu 64* TRANSFER SPLIT FREQUENCY DATA TO ANOTHER TRANSCEIVER to *ON*
Set *Menu 65* COPY SPLIT FREQUENCY DATA TO VFO to *ON*


TS-890S:


Set *Menu 7-04* Quick Data Transfer to *A (TX/RX)*

Set *Menu 7-05 *Overwrite Location (Quick Data Transfer) to *VFO*


TS-990S:

Set *Menu 7-02* Quick Data Transfer to *ON*

Set *Menu 7-03 *Overwrite Location (Quick Data Transfer) to *VFO*

Re: [Elecraft] KPA500-KAT500 tuning settings

[Bob Wilson, N6TV]

Though it works, best practice when using a K3 is to use AUX cables.  The
AUXBUS line (pin 2) in the AUX cable provides notification to the K3 as the
amp switches from standby to operate, so drive power can be adjusted
automatically  AUXBUS also lets you use the band buttons on the KPA500 to
change bands on the K3, which most folks find much more convenient than
cycling through the band up/down buttons on the radio.

I guess that depends on how you define "easily".   Plug and play cables and
plus some menu configuration seems pretty easy to me, if you have a Kenwood
rig.

IMHO, the KAT500 and KPA500 *is* very easy to use with Kenwood radios, with
VFO A auto-track, once connected property.  It's all well documented
in the KAT500
Owner's Manual

(pages 16 - 18), and Elecraft can supply KPA500/KAT500 interface cables for
a long list of non-Elecraft transceivers, listed here:

https://elecraft.com/products/75-discount-on-a-kpa500-kat500-power-combo

The S-BOX  can provide plug and play interfaces in
more complex environments, when you need even more devices connected to the
Kenwood serial port, such as SteppIR controllers and Bandmaster band
decoders.

Some combinations (Icom, Yaesu) do not provide frequency auto-track with
just cables, though Yaesu support should be easy to add to the KAT500 /
KPA500 firmware since they've already done the code for the KPA1500.  In
the meantime, N4PY Pegasus Plus software
 can transform any supported
transceiver's frequency into Kenwood format for the KAT500 as well, plus
there are Icom/Yaesu/Kenwood translating hardware solutions available in
some microHAM devices such as the MK2R+.

In practice, wide split frequency operation is quite rare these days, so
tracking VFO A is usually OK.

Nevertheless, see page 16 - 18 of the KAT500 Owner's Manual

for interfacing to KPA500 and KAT500 via CBL-KENSER500 to a Kenwood rig.
Note the Kenwood TS-590SG menu settings on Page 18.

65 COPY SPLIT FREQUENCY DATA TO VFO

These options may help the KAT500 track split frequencies better, but I
have not traced them to see how they change the output streams.

Re: [Elecraft] K3 (S) Weird Main RX issue

Does rotating the MAIN RF GAIN knob back and forth make any difference?  Or
tapping the ANT or RX ANT buttons a lot to exercise the antenna relays?

I assume both receivers are listening to ANT1, and nothing is connected to
AUX RF or RX ANT.

What happens if you move the coax to ANT2?

Re: [Elecraft] KPA500-KAT500 tuning settings

[Bob Wilson, N6TV]

Steef,

See this recent post for explanation:
http://mailman.qth.net/pipermail/elecraft/2021-April/284736.html.

The KAT500 can auto-track any Kenwood or Kenwood-compatible rig that
outputs frequency data in the format:  "FA00014025000;".  Connect the RS232
RXD line (Pin 2) of the Kenwood rig to the TXD line (tip) of KAT500 PC DATA
connector, with no connection on ring.  You have to use the BR; command to
set the baud rate of the KAT500 PC DATA jack to match the rig's RS232 baud
rate.

You can also uise a program like N4PY Pegasus Plus
 to keep the KAT500 / KPA500 in
sync. with the rig.

The S-BOX-USB provides either capability using standard commercial stereo
and serial cables, with parallel wiring to all logging programs and the
KPA500 XCVR SERIAL connector, so no splitters or custom cables are
required.  If you're using a TS-590S with a working USB port, you can
connect the computer to the USB port and connect both the KPA500 / KAT500
to the TS-590S COM port with such wiring (only wired RXD in parallel, never
TXD).

Modern Yaesu rigs do not output enough digits of information in the FA
command output (they drop most of the leading zeroes).  The KPA1500
firmware can handle the Yaesu format of FA frequency data to auto-track,
but the KPA500 and KAT500 cannot, though they could potentially be updated
to do that.

Re: [Elecraft] [K4FT] K4 software release 13

[Bob Wilson, N6TV]

Installs fine.  I like the new spectrum overlay.

Glad you fixed the AM / FM TX freq. bug.  Will close that one.

Re: [Elecraft] K4 interface to KPA-1500

[Bob Wilson, N6TV]

With a KPA500, just set RADIO to K3, and this works fine with the K4.  No
KPA500 firmware update is needed.

The K4 recognizes the difference between the KPA1500 and KPA500 by the
AUXBUS messages it receives, so it changes popup messages such as "KPA500
Status:  operate" and "KPA500 Status:  standby" to "KPA1500 Status: ..."
automatically.

Yes, identical AUX cable (and/or Y-BOX) works fine.

TX Sample is not yet implemented (could be a while).  I recommend leaving

You may have lost a final.  How to confirn (TNX WE6R):

1. Mode: SSB
2. Band: 160m
3. Power: 10W
4. Speak into the microphone and listen on another receiver.
5. Continue speaking while listening on the other receiver and slowly
increasing the power.
6. If the received audio becomes terribly distorted once you get above 13
or 14 watts, it usually means that you need to have the unit repaired to
replace a final.

Well, a few milliseconds after you transmit, the KPA500's frequency counter
will automatically switch the KPA500 back to the right band.

OK, but for others who may be curious, the KPA500 can automatically track
the band of TS-590S with no computer and no custom code required.  Just a
connect a straight serial cable from the KPA500 *XCVR (RS232)* jack to the
TS-590S *COM* port, and set the KPA500 MENU as follows:

RADIO to SERIAL
RS232X to the baud rate of the TS-590S COM port
SER POLL ON if the TS-590S is the only device connected to the TS-590S COM
PORT
-or-
SER POLL OFF if some other device like an RS232 band decoder is polling the
radio on the TS-590S COM port, in which case both KPA500 and the device can
be connected in parallel to the TS-590S COM port via an RS-232 Y-Cable or
S-BOX.  SER POLL OFF uses a relay to open the TXD pin of the KPA500 RS232
connector, so the usual problems caused by connecting two RS232 devices in
parallel are no problem.


Now the KPA500 will automatically track the band of the TS-590S, as will
an RS232 band decoder or similar.

Re: [Elecraft] K3/KPA500 question

[Bob Wilson, N6TV]

OTOH, if you change Radio type from K3 to BCD, and have set the K3
menu *CONFIG:PWR-SET
*to *PER-BAND*, the K3 will no longer be able to recognize when a KPA500 or
KPA1500 is switched from STBY to OPER, so there will effectively be just
one fixed drive power setting stored per band, instead of two power
settings (one for amp in OPER and a second for amp in STBY).

Re: [Elecraft] K3/KPA500 question

[Bob Wilson, N6TV]

It's not clear why this feature of the KPA500 is a "PITA," since the
majority of users want the rig and the amp. to always be locked to the same
band.  However, I suppose it could be a problem in a station where antenna
switching is all manual rather than automatic.

In that case, one can change the KPA500 "RADIO" menu from "K3" to "BCD",
and now the band buttons will not change the band of the K3 anymore, but
the amp. will still follow band changes made by the K3.

Hope that helps.

Re: [Elecraft] K3/KPA500 question

[Bob Wilson, N6TV]

Does your automatic antenna switch use the Unified Microsystems BCD-10 or
BCD-14 band decoders, or is your design similar to the 4O3A Antenna Genius?

These products all use opto-Isolators on the four Band Data lines in the
AUX cable.  Wiring this type of decoder in parallel with the
K3/KAT500/KPA500 AUX cable via a 15-pin Y-cable or similar *will usually
cause automatic band changes on the KPA500 to stop working*, until you
disconnect the antenna switch's band decoder, or send some RF so that the
KPA500 frequency counter takes over.  Not cool.

Opto-isolators draw too much current from the K3 ACC pins, leaving too
little voltage for the KPA500's band decoder to track properly.  This is no
problem for the KPA1500, only the KPA500, with or without the KAT500.

The solution I discovered was to connect four 4.7K pull-up resistors to 12V
to each band data pin in the K3 ACC cable, assuming the band decoder in the
antenna switch can handle 12V instead of 5V (most can).  The KAT500 and
KPA500 will have no problem with 12V on the band data lines.

The Y-BOX v3.0 (not pictured on my website because I have not had time to
update it) includes these four pull-up resistors.  They can conveniently be
wired internally to the band data pins, and band switching should work
again when all the devices are connected in parallel to the K3 ACC via the
Y-BOX.  This assumes your KPA500 "RADIO" menu is set to "K3" or to "BCD" so
it tracks properly when the automatic antenna switch is disconnected from
the ACC/AUX cables.

FYI, you can still tap the BAND buttons on the KPA500 to change bands on
the K3, because that uses the AUXBUS line (ACC Pin 2), not the BAND DATA
lines.  Many folks may have never discovered this cool feature of the
KPA500 and KPA1500.

The K3S has a built in keyer for your paddle.  And, as K8TE mentioned, you
can also key computer-generated CW and PTT from many (but not all) logging
programs, using the CONFIG:PTT-KEY menu in the K3S to enable CW and PTT
keying over the USB cable's virtual "DTR" and "RTS" pins.  No WinKey
required.

This is covered in great detail in this presentation, linked from my
qrz.com page .

Everything You Need to Know About USB and Serial Interfaces
, presented at 2020 Dayton CTU via Zoom

   - Watch YouTube recording of this presentation here
   .

If you're using N3FJP, my S-BOX-USB  can provide the
second serial port it requires to key CW and PTT via RTS and DTR, merging
these lines into the lone serial port on the K3 or K3S RS232 cable, or
keying via the KEY and PTT jacks with additional cables.

I assume I could still use the hub and now use a USB to USB mini cable to

There is no "USB mini" connector on the K3S.  It's a standard USB Type B
(square) connector.  These connectors are also illustrated in the
presentation referenced above; see Slide 6.

Sorry, the mini HDMI to mini USB adapter does not produce a virtual serial
port.  It provides an HDMI monitor port.  Any USB to HDMI adapters you'll
find on the web are there to convert the USB port on a PC (type A) to HDMI
monitor ports, so you can connect an HDMI monitor if your PC has no HDMI
ports.  But you can't plug those adapters into a K3S (wrong connector).

Just connect a common USB Type A to USB Type B cable from your USB hub to
the K3S, and you'll be in business with both logging software and
(potentially) computer-generated CW and PTT.  Now, if you also want
computer-generated FSK RTTY keying, you can use a device like my S-BOX to
add that capability.   FSK RTTY keying is through the 15-pin ACC connector
of the K3S, which can't be connected directly to a computer.

NEVER plug a VGA cable or a VGA adapter into the K3's ACC connector; it's
the same physical connector type (DE-15F), but it is NOT a VGA monitor
port, and trying to connect a monitor cable there could cause damage.
Never do it.

My other offering, the Y-BOX, is useful if you need to connect multiple
devices to the K3 ACC port, or need a breakout box.  Such devices include
the Mortty FSK keyer, or a microHAM device, or RemoteRig box, in addition
to Elecraft devices like the KAT500/KPA500 and KPA1500, or a band decoder /
automatic antenna switch.

antennas, and 1500W output.  I'm using Array Solutions 200W W3NQN Bandpass
filters and Top Ten Devices coax stubs.  There are two or more contest
stations on the mountains above me (K6TD's remote, and W6NL) that are
line-of-sight, and they can produce very loud signals, S9 +50 dB or more
off the back of my beams.

The front end of the K4D performs just as well, as far as I can tell, as
the two K3 radios I used before, which had 8 pole crystal filters (the
Inrad 500 Hz 8-pole crystal was my favorite).  I've heard no "AGC pumping"
or "desense" on the K4D, from either of these loud stations a few kHz away,
though I can hear their transmitted phase noise, and see it on the K4
scope.  I can transmit on one band and listen on an adjacent band, and
though I hear my harmonics or IMD for neighborhood non-linear devices in
certain directions, the K4D receiver doesn't "block" when I transmit on the
other.

As I've mentioned before, the K4D audio is a vast improvement over the K3
and K3S, which really helps when you're lucky enough to attract a pileup.
The QSK is better too, which helps when you're calling in a pileup.

Furthermore, you DO NOT need to tap multiple times to switch to the RX
antenna, as seen in the recent live demo by WA6HHQ.  What Eric did not get
to demonstrate is that there is an ANT CFG menu option that allows you to
select which antennas you want the RX ANT button to cycle through.  When
that option is selected, a single tap of the RX ANT button toggles the
receiver between the TX ANT and RX1 antennas, say, instead of popping up a
menu, so the K4D can work the same as the K3.  You can also toggle an RX
ANT in and out from the keyboard of your logging software, simply by
sending a host command with a function key. Or you can cycle through
multiple RX antennas with each tap.  The same applies to the TX antennas.

The 8 K-POD buttons can also be used to send host commands (or "macros") to
do anything you can do with a button, or several buttons.

The only time the K4HD model might be best would be when there are two rigs *on
the same band*, such as at Field Day, or at a large DXpedition, or at a
large Multi-Multi station with a RUN and MULT stations on the same band.

And, as I understand it, the plan is that a K4D can be field upgradable to
an K4HD model at a later date.  What remains to be seen, though, is if the
"ripple" in the roofing filters of the HD module introduces any pileup
mush, which was one explanation for why the K3 and K3S still had some
pileup mush, even after the K3 AGC settings and RF Gain were properly
adjusted as recommended here
.
Time will tell.  As of now, I haven't heard any pileup mush (RX IMD or
Audio IMD) in the K4D.

As for noise blanking and noise reduction, it's not something I can offer
an opinion about, because I prefer to leave both OFF, as I did on my K3.

Re: [Elecraft] DB15HD cable sopurce

[Bob Wilson, N6TV]

This appears is the same Amphenol cable that I supply with my devices, for
$12 ea. if purchased with S-BOX or Y-BOX ($10 for a 2.5-ft version).  I
also have a few longer ones.

However, the link points to a M/F cable, which works from my Y-BOX v2.x or
v3.x to AMP AUX, but should never be connected between K3 ACC and AMP AUX.
There must be no connection on pins 1, 4, 6, 7, or 8 when connecting a K3
or K4 ACC to an Elecraft amplifier's AUX connector, which is how the
KPAK3AUX cable is wired.

Furthermore, Jim probably needs M/M cable for a homebrew Y-BOX, not M/F.  I
have those too, in 2.5-ft and 5.0-ft lengths, but I prefer to provide
cables with a purchase of a Y-BOX or S-BOX, or to support those who already
own one, rather than to take time to ship individual cables.

That will probably work fine once programmed to connect to your WiFi Router.

If there's a PC in the shack with an unused Ethernet port, one that
connects to the Internet via WiFi, Windows Internet Connection sharing
could also work, with an Ethernet cable between PC and K4.

Per WA6HHQ, Elecraft is also working to provide a way to update the
firmware via flash drive, where a PC (or MAC?) could be used to download
firmware from a web site.  Obviously updating via direct Internet
connection will be the most convenient.

Yes, you connect the K4 Ethernet port to your Router or Ethernet switch,
then software updates may be downloaded on demand direct from the Internet

Re: [Elecraft] USB monitor issue?

[Bob Wilson, N6TV]

There's a special setting only documented in the K3 Firmware Release Notes as
follows:

* TX LINE OUT (MONITOR) LEVEL NOW ADJUSTABLE: In CONFIG:LIN OUT menu
entry, tap '2'  (REV switch) to set the "T=" level (TX monitor). Tap '2'
again to return to the RX LINE OUT setting.

So if you go to CONFIG:LIN OUT, then tap [2], you can change the sidetone
(or SSB) monitor level to 0.

There is also a "Listen to this device" checkbox in the Windows Sound
Control panel, sound card Properties, that you may need to disable.  Run
mmsys.cpl to locate the USB Audio CODEC, under the *Recording* tab.

Re: [Elecraft] K3 shortening CW dits

[Bob Wilson, N6TV]

I posted various solutions to the K3 element shortening issue about 7 years
ago. See this link on my QRZ.COM page :

   - How to get clean fast CW from an Elecraft K3 without using CW QRQ mode
    (post
   to Win-Test Reflector, November 14th, 2013)

This was before the KSYN3A upgrades, which only helped the keying problem a
little.  Element shortening is still there, and bad CW jitter is still
present in the K3 + KSYN3A at speeds above 37 WPM with external keying.
The internal K3 keyer sounds fine (it compensates), but external keying is
a problem.  With VOX ON (QSK or semi-breakin), no PTT input, all keying
elements are shorted by the TX DLY.  The default TX DLY nor 008 is really
closer to 6 ms delay, after you get the KSYN3A upgrade, hence 6 ms of
keying compensation required.  A high TX DLY for a slow amp. relay makes
the problem much worse.  Keying Compensation is unfortunately not available
in N1MM+ when using the convenient DTR and RTS CW keying over the K3 serial
port or the K3S USB cable (CONFIG:PTT-KEY RTS-TR), but it should be added
IMHO.  This feature is already available in Win-Test.

More details and other fixes (e.g. use software generated PTT, no keying
compensation) are found in that post above.

The K4 has NO CW jitter problems that I've found, but element shortening by
TX DLY is still present, and I've filed bug reports about it, but it's not
at the top of their list yet.

Re: Missing argument in org-reset-checkbox-state-subtree?

[Bob Wilson]

Thanks again Kyle,
   Per your suggestion I have reverted my change to 
org-reset-checkbox-state-subtree, and instead updated 
org-reset-checkbox-state-maybe in org-checklist.el (I’m much happier editing 
org add-ons than editing org!).

Specifically, I follow up org-reset-checkbox-state-subtree with a call to:
(org-map-entries ‘org-update-parent-todo-statistics)

and this seems to address my problem as well, but definitely more elegantly!

Kind regards,
Bob

I have a daily wind-down routine where I respond to any lingering emails, etc. 
So I have an item like:

* TODO Daily Wind-Down
SCHEDULED: <2020-11-12 Thu 17:00 +1d>
- [ ] Respond to emails
- [ ] Pat myself on the back

I use the org-checklist add-on so that marking the task as complete resets the 
checkboxes to empty. But I noticed that every time I do so, it resets the 
statistics cookies everywhere else in the org file! And by reset, I mean it 
replaces things like [5/7] with [0/0]. I have to do C-u C-c # 
(org-update-statistics-cookies ALL) to fix it.

I’m new to elisp, but I tried my best to debug what was going on. I could be 
completely wrong about the underlying cause, but I was able to make a change 
that prevented this phenomenon from occurring. I thought other people might be 
having the same problem, but it sounds like maybe not!

Just for completeness, I will write out my thoughts (and you’ll soon see just 
how little I know of elisp — I apologize!). Here is the 
org-reset-checkbox-state-subtree as of 9.4:

(defun org-reset-checkbox-state-subtree ()
  "Reset all checkboxes in an entry subtree."
  (interactive "*")
  (if (org-before-first-heading-p)
  (error "Not inside a tree")
(save-restriction
  (save-excursion
(org-narrow-to-subtree)
(org-show-subtree)
(goto-char (point-min))
(let ((end (point-max)))
  (while (< (point) end)
(when (org-at-item-checkbox-p)
  (replace-match "[ ]" t t nil 1))
(beginning-of-line 2)))
(org-update-checkbox-count-maybe 'all)

In the last line, it calls org-update-checkbox-count-maybe with ‘all argument. 
I don’t full understand the single quote part. My understanding is that it 
tells lisp not to evaluate the value (which is good, because there is no all 
variable defined at this scope). My only idea here is that it’s a way of 
saying, “by the time you actually need this value, I’ll have told you what it 
is”. But what is relevant is that I don’t think ‘all is nil; it’s some kind of 
placeholder, so it effectively gets evaluated as true. Or so it seems to me.

org-update-checkbox-count-maybe passes this placeholder unmodified to 
org-update-checkbox-count which does all the heavy lifting. But nowhere is the 
all argument ever modified, it continues to be that non-nil placeholder, which 
seems to get evaluated as true. It’s not clear to me why this placeholder would 
get passed to the function if it is never set to anything else. But again, I 
don’t fully understand the single quote syntax.

The org-update-checkbox-count is quite complicated (from my elisp-neophyte 
perspective), so it is not clear to me why it resets the statistics cookies to 
[0/0], but whatever it does, it does it in the entire file.

The “fix” that I made was on the first and last lines of the function:

(defun org-reset-checkbox-state-subtree ( all)
...
(org-update-checkbox-count-maybe all)

where you can see all I did was remove the single quote from all, and added all 
as an optional parameter. Now I feel like this was the wrong fix, but it does 
solve my problem! Maybe the real problem had nothing to do with the entire 
buffer part, and was more about why the statistics cookies get updated to [0/0].

Here is a minimal example that showcases the problem (without my “fix” in 
place):

* Task A [1/2]
** DONE Subtask A.1
   CLOSED: [2020-11-12 Thu 08:47]
** TODO Subtask A.2
* TODO Daily Wind-Down
  SCHEDULED: <2020-11-12 Thu 17:00 +1d>
  :PROPERTIES:
  :RESET_CHECK_BOXES: t
  :END:
- [ ] Respond to emails
- [ ] Pat myself on the back

Marking the Daily Wind-Down as complete resets the buffer so it looks like:
* Task A [0/0]
** DONE Subtask A.1
   CLOSED: [2020-11-12 Thu 08:47]
** TODO Subtask A.2
* TODO Daily Wind-Down
  SCHEDULED: <2020-11-13 Fri 17:00 +1d>
  :PROPERTIES:
  :RESET_CHECK_BOXES: t
  :LAST_REPEAT: [2020-11-12 Thu 08:47]  
  :END:
- [ ] Respond to emails
- [ ] Pat myself on the back

The first line shows the problem: the statistics cookies have updated to [0/0].

For what it’s worth, my “fix” may be the wrong fix, but it does solve the 
problem! So if anyone else runs into the same problem, I hope my horrible elisp 
debugging is mildly helpful!

Kind regards,
Bob Wilson

Missing argument in org-reset-checkbox-state-subtree?

[Bob Wilson]

Hi folks,
   I’m writing about a possible bug in org-reset-checkbox-state-subtree. This 
function calls org-update-checkbox-count-maybe with argument 'all, but this 
value is not defined in the function (or anywhere else that I can see). 

I’d like this value to be nil because I don’t want to update the statistics 
cookies in the entire buffer, but I don’t see a way to do this (pardon my 
limited elisp). My workaround is to add an optional all argument to 
org-reset-checkbox-state-subtree and pass it to org-update-checkbox-count-maybe.

This seems like the desired functionality unless I’m missing something. Is the 
current implementation intentional?

Kind regards,
Bob Wilson

Re: [Elecraft] KPA1500 / K3 Mystery

[Bob Wilson, N6TV]

Bruce,

What is the firmware version of your KPA1500?  2.48 is the latest.  There
was also a change in version 2.38, almost a year ago, that could fix the
issue for you:

02.38 11/4/2019 (Production 12/3/2019)
⦁ Switch to STBY if BAND CHANGE->STBY is enabled and the frequency (from
XCVR or TX count) is below the amp's frequency range
⦁ Wait longer after band change to inform K3 that KPA1500 has switched to
STBY when BANDCHANGE->STBY is YES

Many hams are old with shaky hands and many also suffer from Parkinsons

By TUNE POWER I assume you mean the *TUNE LP* menu setting.  The *TUNE
LP* setting
now defaults to only 5W (used to be 10W).  So, using all the Elecraft
defaults, tapping the ATU TUNE button on the KPA1500 won't always work,
because the amp.'s tuner will only get 5W drive instead of 20W.

Re: [Elecraft] KPA500 REMOTE POWER CONTROL

[Bob Wilson, N6TV]

KPA500 AUX Pin 12 is GND.  AUX Pin 8 is the KPA500 remote power ON/OFF
pin.  No webswitch is necessary to remotely power the KPA500 on and off,
since this can be done quite easily from a button on the K3 itself, using a
macro, as described here:

Re: [Elecraft] P3 info

[Bob Wilson, N6TV]

I recommend checking the P3 Manual for the correct hookup.  You can either
use the optional CBLP3Y cable (a separate purchase) or the RJ-45 to DE9-F
adapter cable that is supplied with every K3S.  If using the latter, you
have to change CONFIG:RS232 to 38400 (not USB), and the USB cable can
only be used for the USB Audio CODEC, not rig control, and you use the same
serial cable you were using before, with the K3.  Otherwise, you need to
use the CBL3P3Y to make everything work with one USB cable (CONFIG:RS232
USB).

Links in complete org-todo-keyword-face not highlighted

[Bob Wilson]

Hi folks,
   I often put links in TODOs, but it would appear that in org 9.4, marking a 
task complete changes the font of the entire text (link and non-link) to be the 
same color, so the link is no longer highlighted.

Minimal org file:
```
* TODO This is a [[https://www.gnu.org][test] <https://www.gnu.org%5D%5Btest]>]
```

When I open this in emacs, it looks like:
```
* TODO This is a test
```
with “test" being highlighted blue and underlined. When I mark it complete, it 
looks like:
```
* DONE This is a test
```
with “test” being brown, the same as the rest of the test. Notably, if I 
position point over test and hit “C-c C-o” the link still opens, so the link is 
definitely still there, it just looks the same as the rest of the header. That 
leads me to believe it is an incompatibility between the org-link face and 
org-todo-keyword-face, but I’m not 100% sure.

- Using emacs 26.3 on my personal laptop and 27.1 on my work laptop (problem 
occurs in both versions).
- Using Mac OSX Catalina everywhere.
- Using org version 9.4. I’m not 100% sure, but the problem doesn’t seem to 
have been present in 9.3.6, which is what I was using before upgrading to 9.4. 
I’ve been using 9.4 on my work laptop for a week or so, but was using 9.3.6 on 
my personal laptop. When I noticed the problem on my work laptop, I checked if 
it was also present on my personal laptop, but the behavior was as expected 
(link remains highlighted, font did not change colors at all actually when 
marking as complete). When I upgraded my personal laptop to 9.4, the problem 
appeared there too.
- No init.el (or .emacs) file. For some reason the problem does *not* occur 
when I run `emacs -nw -q`, but it does occur when I run `emacs -nw` after 
renaming my init.el file. I thought -q was equivalent to ignoring the init.el 
file, but I guess not!

I tried searching the mailing list to see if this has been discussed previously 
but didn’t see anything. Any help would be appreciated!

Kind regards,
Bob Wilson

Re: [Elecraft] Does the K4 support IPv6?

Using a web browser on Windows, on the same LAN / Router as the K4, if I go

Re: [Elecraft] Does the K4 support IPv6?

[Bob Wilson, N6TV]

I'm not sure what you mean by "support IPv6".

>From a Windows command prompt, I tried a *ping -6* command with the radio's
IPv6 address, to force IPv6 addressing, and it responded just fine.

But it sure is easier to type the radios IPv4 address, which the rig
displays in the menu.  It doesn't display the K4's IPv6 address, but my
Router interface displayed it.

What application do you plan to use that requires IPv6?

On the KX3, the ACC2 connector (a 2.5 mm stereo or "TRS" jack), TIP is PTT
IN (for a footswitch or computer-generated PTT if you set *ACC2: IO* to
*LO=PTT*), and ring is KEYLINE OUT (for an amplifier).  So RING of ACC2 is
the one to connect to key the amplifier relay with a KX3.

I can't tell which of the sections on a TRRS jack to use. Ring 2 or ring 3?


The only TRRS jack on the KX3 is the MIC jack.  Ring 2 is Logic Ground and
Ring 1 is PTT IN (push-to-talk switch) or UP/DOWN.  Do not connect the mic.
jack to the amp.

 Also don't know how much current is on that amp key line. Measured 15V DC
> when it is on and off measured 400 ohms, if that is any help.


Just put your meter into "AMPS" or "MilliaAmps" on the highest scale, and
measure the current across the KEY IN or "RELAY" jack of the amp with the
meter while it is powered ON.  The amp. should go into TX mode when the
meter shorts that terminal to ground.  Chances it's well within the limits
of the KX3 KEY OUT line (30V, 100ma max).

BTW, the S-BOX or S-BOX-USB makes a nice "docking station" / computer
interface for a KX2 or KX3, if you need one.  Rig control plus
computer-generated CW and PTT over a single USB cable can be provided,
along with all the required interface cables.

Re: [Elecraft] No Tx audio after WSJT upgrade

[Bob Wilson, N6TV]

Most likely causes of no TX Audio in a K3S with WSJT-X:

   1. Any connector or cable inserted into the K3S 3.5mm LINE IN jack will
   override (and completely MUTE) the USB Audio CODEC input
   2. USB Audio CODEC "Speakers" level got reset to 0 by Windows
   3. MAIN:MIC SEL for DATA mode is not set to LINE (so MIC GAIN knob
   adjust MIC level instead of LINE IN level)
   4. Wrong sound card selected in WJST-X
   5. MON level set too low to hear your transmit tones

If the USB cable is disconnected from the K3S, the USB Sound Card (USB
Audio CODEC) will no longer be available.

You have to switch WJST-X to use the sound card in your PC.  And you
have to run two cables:

K3S LINE OUT to PC LINE IN (or MIC)
K3S LINE IN to PC LINE OUT (or SPKR/Headphones)

Adjust levels using the Windows level controls and CONFIG:LIN OUT and the
MIC GAIN knob (which adjust LINE IN level when MAIN:MIC SEL is set to LINE).

Re: [Elecraft] KPA-1500/FlexRadio 6400

[Bob Wilson, N6TV]

Hi Mike,

This seems to be a duplicate post (see
http://elecraft.365791.n2.nabble.com/KPA-1500-FlexRadio-6400-td7665007.html),
though I'm not sure if your questions were fully answered the first time.

First, to search the archives of this reflector, go to
http://elecraft.365791.n2.nabble.com/Elecraft-f365791.topics.html and use
the search box, top right.

To get the KPA-1500 to track the exact frequency of the Flex (before you do
any transmitting), you need to set up a proper connection between the 3.5mm
stereo jack on the back of the KPA1500 labeled "XCVR SERIAL" and one of the
common USB Type A connectors on the back of the Flex.

   1. Use any of the following to make a serial connection between the two
   devices:
  - FTDI USB-to-Serial adapter + Elecraft KXSER cable
  - Elecraft KXUSB cable
  - Serial Box USB (https://bit.ly/S-BOX) + stock serial and stereo
  cables

  2. For amp. keying, connect an ordinary RCA male-to-male patch cable
   between the RCA connector on the back of the KPA1500 labeled "KEY IN" and
   the RCA connector on the back of the Flex labeled "TX1"

   3. In the KPA1500 Menu, set

   RADIO TYPE: SERIAL

   SERIAL SPEED XCVR: 9600
   RADIO POLL: ON
   4. In the FlexRadio SmartSDR Setup, select the new serial adapter that
   appears when connected to the back of the Flex
   *Settings | USB Cables*
 Cable Type:  *CAT*
 Source: *TX Slice*
 Auto-report:   *Disabled*
 Advanced: *9600,8,N,1*
 Flow Control:
*None **Settings | Radio Setup*
 Transmit tab
 RCA TX1:  5 ms
   Enabled

The KPA1500 and its tuner (if enabled) will now automatically track the
exact frequency of the Flex, and be keyed by the Flex when it goes into
transmit.  You can verify the frequency by setting TECH MODE to ENABLED in
the KPA1500 menu, then scroll the STATUS page of the KPA1500 LCD until you
see XCVR FREQ and TX COUNT displayed.  XCVR FREQ is the frequency reported
by the radio over the Serial connection.  TX COUNT is the approximate
frequency detected by the KPA1500's built-in frequency counter whenever you
transmit.

If you have trouble making this work, feel free to contact me directly.

Re: [Elecraft] CW Sidetone and Line Out?

[Bob Wilson, N6TV]

There's a special setting only documented in the K3 Firmware Release Notes
 as follows:

* TX LINE OUT (MONITOR) LEVEL NOW ADJUSTABLE: In CONFIG:LIN OUT menu entry,
tap '2'  (REV switch) to set the "T=" level (TX monitor). Tap '2' again to
return to the RX LINE OUT setting.

So if you go to CONFIG:LIN OUT, then tap [2], you can change the sidetone
(monitor) level.

Span and center frequency are adjustable.  Fixed or tracking mode is
available.  Scrolling mode (to prevent VFO cursor from going off screen)
has different options, similar to P3:  full page, half page, slide, etc.

Probably it will work the same as a K3.

I don't think that will work.  Connecting a separate SDR to RX ANT OUT
would be a simpler way to do it.  A program like HDSDR can keep the SDR
frequency in sync with the K4 frequency.

Re: [Elecraft] Cable for K3 to Expert 1.3K-FA

[Bob Wilson, N6TV]

Joe,

A single cable can work, but it may not be the ideal solution for the long
run, should your equipment expand or change.

Instead of a custom K3 to SPE cable, consider an alternative that will
allow stock cables to work, no matter which radio or amplifier you want to
connect.  I designed the Serial Box (S-BOX ) to make
it easy to connect the K3 (or any modern transceiver) to any device
designed to monitor serial port traffic for automatic band switching and
auto-tuning, including all SPE Expert amplifiers and most ACOM automatic
amplifiers, plust the Elecraft KPA1500 and any serial port band decoders /
antenna switches and SteppIR controllers.  The goal was to allow all of
these devices to track the transmit frequency of the transceiver
automatically (not just the band), with all devices switching at the same
time.  The S-BOX can also be configured to support the custom "null-modem"
connection from the 9-pin SPE "PORT" terminal to a SteppIR controller, if
you have more than one transceiver connected to the SPE, and are using both
inputs.  The SPE firmware automatically translates the frequency data of
the active radio to a common format for the SteppIR controller.

Using a simple cable with "Band Data" pins on the K3 ACC connector (instead
of serial data) isn't ideal if you intend to use the Expert's built-in
tuner on some band segments, because that cable only provides band
information to the amplifier, instead of frequency information to the tuner.

Using a simple cable to the K3 RS-232 connector precludes using it for
other purposes, such as a logging program.

The S-BOX was designed to work around these common interconnection issues.

Re: [Elecraft] That's a whole lotta buttons and knobs!

[Bob Wilson, N6TV]

IMHO, both the RIT/XIT knob and RIT clear button in the Kenwood ST-995sdr
image are poorly located.  I wouldn't recommend this radio for "big gun
contesting" unless they offered an outboard RIT knob with an RIT clear
button, like the Elecraft K-POD, or the old Ekletech outboard tuning knob
(made by K9SD).  Perhaps it was designed primarily for military use?

However, I do like the concentric knobs in the Kenwood.  Concentric optical
encoders are (or were) quite expensive, which is why the K4 doesn't have
any.  The only concentric knob on the K4 is the AF and SUB AF gain knob,
which is a POT.

I expect this new Kenwood transceiver will generate sticker shock when the
price is finally announced, similar to the Icom IC-7851.

Re: [Elecraft] [K3s] SteppIR Control

[Bob Wilson, N6TV]

Hi John,

If you have *CONFIG: RS-232* set to *USB*, then both K3 serial ports are
fixed at 38400 baud, so you have to use that setting in the SteppIR
controller, and set the radio type to Elecraft (or Kenwood).

A custom cable is required to allow the SteppIR auto-track to work via the
K3 9-pin serial port at the same time.  This is something I implement in my
Serial Box (S-BOX ) offering so that one can use
standard economical serial cables and omit all Y-adapters and expensive
custom SteppIR cables.

The serial cable connection from the SteppIR to the K3S serial port (via
the Elecraft RJ-45 to DE-9F adapter cable, P/N E980297) must make no
connection on Pin 3 (TXD), and Pins 7 and 9 must be shorted.

Finally, a logging program must be actively polling the K3, or CONFIG:AUTO
INF must be set to AUTO 1, or else the SteppIR won't get any frequency data.

If you are also connecting a P3 via the CBLP3Y, then a serial Y-cable or
S-BOX must be connected to the P3 "PC - RS232" port, with one side going to
the CBLP3Y male DE-9 connector, and the other side going to the SteppIR
cable.

Re: [Elecraft] Cable for K3 to Ameritron ALS-1300/ARI-500

[Bob Wilson, N6TV]

NEVER connect an SVGA cable to an Elecraft ACC/AUX port, unless you have a
way to test every single pin.  Many of these cables short all the "ground"
pins together (there are 5 of them), or omit Pin 9 (K3 Band2 OUT), so they
won't work at all and could cause damage.

No, you can't run N1MM logging program and P3 or K3 Utility at the same

I'm sure a number of P3+P3SVGA will be available on the used market soon,
given all the folks planning to upgrade to the K4.

Meanwhile, you can get much better and faster screen grabs using an
off-the-shelf HF SDR with the antenna port wired to the K3 RX OUT
connector, and free software like HDSDR.  No need to use the P3.

[Elecraft] Connecting KX3 or K2 to KPA1500 (or KPA500)

My Serial Box (S-BOX  or S-BOX-USB) can provide both
a computer interface to the K2 or KX3 for logging software (including
computer-generated CW and PTT keying over the same cable).  *Plus*, it can
also provides a parallel RS-232 connection to the KPA1500 XCVR SERIAL port,
all using standard stereo cables (3.5mm TRS to dual RCA-M) and a
KXSER-compatible cable (DE9-F to 3.5mm TRS) , all of which which I'll be
happy to supply with the S-BOX or S-BOX-USB.  The same scheme can work with
the KPA500.  Placing the amplifier in "no poll" mode means the logging
program must be responsible for polling the radio for frequency data,
instead of the amplifier.  No polling, no tracking (except by "RF sense").

If you have no need to control the KX3 or send CW by computer, and just
want the amp. to poll and track the KX3, then building your own 3.5mm TRS
crossover cable would be the most economical solution.

Connection of the KIO2 connector of a K2 to the KPA1500 through the S-BOX
is also possible with a standard RS-232 cable as long as the "PC" connector
on the S-BOX is not used (which would connect too many lines to the KIO2
DE-9 connector).  One of the S-BOX secondary DE-9F connectors (or
builtin-in FTDI USB-to-Serial adapters) can be used instead to just connect
the TXD, RXD, and Ground pins to the KIO2, leaving the others open.

I don't know if the KIO2 AUXBUS line (pin 6) is compatible with the KPA1500
AUXBUS line (pin 2), but if so, this connection is also possible through
the S-BOX's 15-pin connector and a 15-pin M/F cable, which I can also
supply.  I don't know if the ACC2 AUXBUS option on a KX3 is compatible with
the KPA1500 AUXBUS.

There's really no urgent reason to do this once the KY host command is
improved to allow message stacking with interrupt capability.  If you want
to use TinyFSK (which has its own problems), connect a Mortty to the K4 ACC
port, same as you would on a K3.  If you don't want to solder your own
DE-15 connector, or if your ACC port is already occupied, use a Y-BOX
 plus 3.5mm stereo to dual RCA cable to connect
Mortty to K3 or K4.  I have a few of both still in stock.  It will take a
few weeks to order more boards if there is sufficient demand.

This is already in plan.  The K4 provides two virtual serial ports via the
USB cable (FTDI), one legacy 9-pin serial port, plus the 15-pin ACC port.
Any of them may be used for FSK keying, PTT, and CW keying, using MMTTY or
your logging software.  This is keying via TXD, DTR, or RTS pins, with no
external hardware required (unless using ACC pins).  EXTFSK will be
required on the virtual serial ports.  The 9-pin legacy port will not
require EXTFSK if your PC serial port or USB-to-Serial adapter doesn't
require it (example:  Edgeport/4).

  The FSK could emulate tinyFSK and the keyer could emulate the K1EL

There will be no more fights over the serial port because the K4 has more
than one, and they will operate independently and in parallel (unlike
Icom rigs, which provide one and only one virtual serial port pin at a time
for PTT keying).

TinyFSK has a problem.  Using it with MMTTY and a Mortty, try the "send
RYRYRY... forever" macro while using TinyFSK.FSK.  Hear the problem?  It
hesitates every 32 characters or so.  So its timing is not as "perfect" as
claimed, at least not with that configuration.

While I despise the following phrase as a SW guy (specifically embedded

As a software guy, you can appreciate that it is impossible to perfectly
emulate someone else's code (or chip) if you have no access to the source
code, and only work from the external API.  Lots of devices have attempted
to emulate the WinKey interface, but none of them are 100% compatible with
the chip.  This includes RemoteRig boxes, the YCCC SO2R Box, the Mortty,
etc.  None of them will pass the WKTEST program (
https://www.hamcrafters2.com/WKTESTX.html), last time I tried.  The
RemoteRig emulator works OK with N1MM+, but not with Win-Test or DXLog.net
(unless you select a unique option).  These programs all use the WinKey
chip differently.  They work fine with a real chip not with the emulators.
The only devices that pass the WinKey 100% compatibility tests are devices
that use a real WinKey chip inside, such as those provided by the microHAM
devices.

Retooling the K4 to put a real WinKey chip or Mortty hardware inside, or
attempting emulation via firmware, could delay K4 shipment or distract from
other higher priority issues.  It could also raise the price a bit.  I
don't think anyone wants to see either.

Finally, there's no reason for Elecraft to try to take sales opportunities
away from the manufacturers of WinKey and Mortty devices, is there?

RE: [DOG mailing list] Cooling airflow and Mixture relationship

[Bob Wilson]

Rob,



We recently did a lot of research to prove or disprove the cooling 
rate/performance on a new engine install in a Taifun 17E2.

The engine is a Rotax 914. Replacing a Limbach 2400.

Our manometer was in fact an ASI using the pitot side on the high pressure side 
and the static on the low pressure side..

This works very well.

We in fact ended up removing all baffles that had been set up in the 
conventional style to achieve the cooling required, but for a Limbach it would 
be very different as the Rotax is water cooled.

Our main areas of concern were water temp, importantly oil temp. and barrel 
temp.

We did have a separate FG shroud (Rotax) around the barrels which was supplied 
air directly from the cowl front by a separate opening.

All results were extrapolated to a 38C day to meet the safe operating temps.

The result was two oil coolers set up in series.

The results have been very pleasing, surpassing the upper temp up to an ambient 
of 44c.

We have an oil thermostat and hence cold temps were no issue.

The bottom cowl was enlarged and had a moderate turndown lip with sidewalls. 
This is most effective.

Subject: [DOG mailing list] Cooling airflow and Mixture relationship



G'day Everyone,

As many of you will know I am OCD about sealing every tiny air leak in the 
Limbach engine bay compartment with silicone, aluminium tape and rubber cowl 
seals.



I have previously rigged up a water manometer in the cockpit with the tubes 
running to the top and bottom of the engine. It told me I was getting very good 
pressure difference but I didn't take much notice of the actual measurements. I 
think it was somewhere around 30cm.



As well as the ram air going into the front of the engine the lower cowl is 
designed to "suck". We fitted a big scoop type bottom cowl which seems to suck 
pretty well particularly with the baffles tightly sealed with silicon.



What I am wondering now is. What is the effect of this extra suction at the 
back of the engine on the carbs and mixture?



Maybe it is not much different to flying at altitude and the SU carbs altitude 
compensating ability can deal with it.



Any fluid dynamics physics experts in this Dog group who can enlighten me?

Re: [Elecraft] K4 and RTTY question

[Bob Wilson, N6TV]

Bill,

Before it can be "fixed" in the K4, the logging software has to be fixed to
send the proper KY command.  If it is sending KY*somes-string*;,
then the messages are not going to be chained.  If it is sending KYW
*some-string*;, then the messages should be properly chained, perhaps with
a very brief pause in between if 0x04 (Ctrl-D, ^D or EOT -- ASCII End of
Transmission character) is appended at the very end of a each chained
message, before the terminating semicolon.  The "W" means "wait for message
completion," as documented in the K3 Programming Manual.

However, once a message sent via KYW starts, you will not be able to
interrupt the transmission by pressing "Escape" or sending an "RX;"
command.  The RX; won't be processed until the message completes, which
isn't very helpful.

Maybe *that* will be addressed (somehow) in the K4.

In sum, if you need chaining more than you need message interrupt
capability, use KYW in your macros.  If you need message interrupt
capability more than you need chaining, use KY.  If you need both,
maybe you'll have to "wait" (sorry) to see if the K4 team comes up with
some way to interrupt chained messages already in progress via a special
"high priority" software command or key tap.

To review, on a K3S or K3+KIO3B with USB connector, you get one virtual
serial port and one USB Sound Card (USB AUDIO CODEC).  Windows cannot
separately set the record level of the left/right audio channels of the K3S
sound card.

With the K4 USB connector you get *two* virtual serial ports on the USB
(similar to IC-7610) and a new USB Sound Card that Windows recognizes as
"LINE" instead of "MIC", so you can set the left/right recording levels
separately, if needed for critical SO2V RTTY Contesting.  The second serial
port is ideal for computer-generated CW, FSK or PTT keying (via RTS/DTR
pins) for programs like N3FJP (and HRD?) that cannot do both CW keying and
rig control on the same serial port, or programs like MMTTY that need a
dedicated serial port for FSK keying.  Port sharing software not needed.
An FSK keying circuit on the K3 ACC connector is no longer needed (but is
still supported).

There's also a separate and independent female DE-9 RS232 connector ideal
for connecting non-Elecraft amplifier "CAT" cables or SteppIR controllers.
This port operates independently of the USB serial ports so no special
Y-Cables needed, and it can use a different baud rate; the device is
allowed to poll the K4 at the same time that a logging program is polling
the radio on a different port (not possible on K3 or K3S).

Will all over them be accessed over ethernet or can you also use USB?


Ethernet can be used too, but it is optional.


> What software will you need to run on your computer?


Same as you would for K3, with enhancements developed over time to take
advantage of K4's extra capability, such as FSK keying over serial port.

Can you run multiple copies of a wsjt-x and monitor different
> bands/frequencies simultaneously?


Monitoring two bands will be possible with a K4D model if a Sub Receiver is
enabled.  However, we'll have to tell the second instance of WSJT-X to read
"VFO B" instead of "VFO A" to display the SubRx frequency, and transmitting
one both would require constantly switching between "SPLIT ON" and "SPLIT
OFF".  Of course, while one VFO is transmitting the other won't be able to
receive since all receivers are muted during transmit.


> Will you be able to transmit on each of those bands seamlessly?


Not sure what you mean by seamlessly.  It's treated as one radio with two
VFOs, and you can transmit on VFO A if SPLIT is OFF, or transmit on VFO B
if SPLIT is ON.

Two bands.  There are only two audio output channels, not four.

1500W.  Shack is right below the antenna.  Analog connection to microHAM

Radio was in full QSK mode.  The K4 QSK is much faster than the K3, so you
hear much more band noise between elements.  Sidetone volume was low.  Band
noise was high.

No RFI into the radio, just into the recording device.  Recordings made by
the radio's sound card will have no RFI issues.  But SO2R recordings
require an external sound card.

Re: [Elecraft] N6TV recording K4 K3

[Bob Wilson, N6TV]

Hi Doug,

I've been doing CW contests with the K3 for nearly 11 years now.  After
using an early release of the K4 firmware, which should only improve over
time, I'm convinced that the K4 far outperforms the K3 in CW pileup
scenarios, mainly due to much improved audio performance.  I predict other
Field Testers will come to the same conclusion, but I'll let them speak for
themselves.

Wayne can explain technically why this is the case (the K4 DAC hardware and
CPU is 11 years newer and faster of course), but all I can ask is to listen
closely to the first recording I posted
.
Please ignore the RFI artifacts during transmissions, and just listen to
the callers, preferably with headphones and a good PC sound card, not a
phone or tablet.  Try to pick out a callsign from the pile.  Then rewind
and try to pick out the *other* callsign.  I think you'll be able to get a
partial or full callsign almost every time, assuming normal hearing and
"contester ears," even though the stations are quite close to each other.
In a K3, under similar conditions, I would often hear annoying "beat notes"
or "buzzes" (audio distortion) with as few as two callers in the passband.
I have yet to hear that in the K4, though of course I've only used it for 6
hours of contesting.

But I've heard enough to place an order for a 2nd K4, mainly so that I can
do SO2R with two identical radios.

Disclosure:  I am not paid or employed by Elecraft, I have never worked
there, and I receive no compensation from the company beyond a small
discount on the price paid for an early Field Test Unit, and the chance to
play and provide direct feedback to the company before the general
release.  Fun stuff (and more work than you might think).
