Re: [Elecraft] KPA500 installation on side?

[Mark Goldberg]

My other option is to put it a few inches above a Xantrex Prosine inverter
/ charger. On the road it will be powered by that inverter anyway, so maybe
proximity is not a huge issue. I need to filter it anyway. They do have
quite a bit of filtering in there already, but I could hear the birdies
from the charger when it was running. It's a Sprinter based RV, not very
big, and under the rear seat is where I have room and it is close to the
antenna feed.

Re: [Elecraft] OT: Re: Baker Island - Tnx Elecraft!

[Eric Swartz - WA6HHQ, Elecraft]

Hi Dave,

Their good ears were due to good ops, using K3S with its clean TX noise and 
excellent RX, and of course our amps helped them on TX. :-)


Congrats on the Q's!

I would echo the comments about the Baker/ Howland Island DXpedition and 
Elecraft. I am only on two HF bands: 160 and 10 meters. I figured that ten 
meters was a stretch, but that 160 meter CW was possible from Maine with a 
little luck. I was away from my shack for most of the operating period, but 
managed to get home on July 3rd and set my clock alarm for 4AM on July 4th for 
about the last chance to work them.  When I got on and listened at 0800 UT I 
heard nothing. No KH1 and no callers either. I parked on 1822.5 and set my TX 
up 1 kHz. I heard static crashes and white noise for about an hour. No signals 
heard at all!! I was all set to give up, and was reading an article on the 
web, when, all of a sudden, KH7Z popped out of the noise, weak but fairly 
audible calling CQ and UP.  I was startled by how fast they peaked up from 
nothing and called them once. Imagine my surprise when they answered my first 
call. (Someone had really good ears!) I could not believe it and called them 
again. This time I was sure they heard my call and we completed the contact.  
I just sat there in awe contemplating the fact that I had them in my log 
within one minute after they first appeared out of the noise on 160 meters. 
The contact took place right at sunrise.  I suspect that the KPA-1500 was 
working overtime on 160 M. Thanks Elecraft for the support of the operation, 
and thanks for making such a nice receiver that is the K3! I used diversity 
reception with two beverages. The TX antenna is a single vertical.  All I can 
say is WOW!

Re: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied

[Don Wilhelm]

The computer is the DTE device, and those devices designed to connect to 
the computer via the serial port are normally wired as DCE devices.


The original thought when the IBM PC serial port was designed was that 
the PC would be used as a terminal connected to a modem, thus the 
decision was that the PC should be a DTE - and for the first several 
years the PC was used only as a terminal device.  Yes, I was involved 
during those early days, but not as a part of that decision making 
process - I was involved with the IBM PC modems.  My manager said I had 
"M" engraved on my forehead.


Now we have the situation where the computer is the controller.  It 
would be very confusing to change the wiring of the computer, so it 
remains as a DTE, and connecting devices (while not modems) are 
configured as a DCE,

No TXD is TXD all the way through the path.  Yes, the DTE TXD will have

One end's TXD is the other end's RXD. That's obvious to those who have used 
RS-233 for a while but if someone needs to ask then it may not be obvious. Find 
the TXD pin on the source and connect it the RXD pin on the destination. 
Sometimes it's easier to look with a scope than to try to understand the 
documentation.

Re: [Elecraft] KPA500 installation on side?

[Jack Brindle via Elecraft]

I know that there are feet are on the right side of the case, but if I were to 
place the KPA500 on its side, i think I would create a stand so that it can sit 
on the left side. Why?
The big weight (power toroid) is on the left side, while the heat generators 
(the PA transistors) are on the right. The center of gravity would be lower, 
cables would be down low (especially the power cable), and the fans up high. 
The only heat generators on the left side are the power regulators (for +5 and 
+12V). They don’t generate nearly as much heat as the PA. The down side? The 
carry handle is on the left. That’s why a short cradle would be needed to lift 
the case above the handle extension.

Just opinion, not an official recommendation. Mine sits nicely on its bottom 
feet with the KAT500 on top. That allows me to cable the two very nicely using 
custom cables.

Re: [Elecraft] OT: 7300 vs 7610 question

[tomb18]

HiWhat?? That's the first I've heard of that! There is no built in web server. 
In fact all the networking of the Icom radio protocols are proprietary and 
encrypted. Currently, you can only use it with the rs ba1 software via a 
network although that will change shortly :) 73 Tom va2fsq.com

It's true that the IC-7610 is simply two IC-7300 type receivers in one 
box. But, it IS dual receive - which is nice. Another impressive feature 
is the built-in web server. Remote control is simple and accessible from 
any PC. Otherwise, it has the features you would expect in a mid-range 
transceiver. And, of course, the K3s maintains the lead in receiver 
performance.

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

    Both 20m & 40m seemed fair.  Deep QSB on both but the noise level 
was not too high so I could copy fairly deeply into the valleys.  
Temperatures were higher for almost everyone except Ken who was camping 
in Northern Minnesota.  Rain kept it chilly for him as he was running 
his KX2 on a battery from his trailer. Storm noise was rather low, I was 
only hearing it in the distance.  I did catch a few strays but WES was 
hot and heavy when I started on 20m.



  On 14050.0 & 14050.5 kHz at 2200z:

I worked John in Michigan and then got pushed off the frequency by WES 
folks up to 14050.5 kHz.


NO8V - John - MI

K0DTJ - Brian - CA

K4TO - Dave - KY

WM5F - Dwight - ID

K6XK - Roy - IA

W0CZ - Ken - ND

K6III - Gerald - CA

- I never could make contact with K4JPN but I am sure I heard him at 
least twice.


  On 7045 kHz at z:

NR5NN - Jim - CA

WM5F - Dwight - ID

K0DTJ - Brian - CA

K6PJV - Dale - CA

W6JHB - Jim - CA


   20m was stronger than 40m since I could compare K0DTJ and WM5F on 
both bands.  I think the QSB was deepest on 20m sometimes ranging from 
S0 - S6 or 7.  On 40m the range was about two S units.  Now to enjoy a 
cool evening before the week really heats up.  By the end of the week it 
should be in the high 90s during the daytime.  I plan to stay underneath 
the canopy of the forest and avoid the sun.


   Until next week 73,

  Kevin.  KD5ONS

Re: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied

[ANDY DURBIN]

"No, TXD is TXD all the way through the path.  Yes, the DTE TXD will have the 
drivers, and the DCE will have receivers, but it is TXD from end to end.  RXD 
is the other way around because the DCE drives that line.  Transmit and receive 
are named with respect to the DTE."

That's great when one equipment is designed to be a DTE and the other as a DCE 
but sometimes that's nor the case.  I think I have connected more equipment 
with a 2-3 3-2 connection than with 2-2 and 3-3 connection.
Perhaps I should have said  - identify the transmit pin on the source and 
connect it to the receive pin on the destination.

Re: [Elecraft] OT: 7300 vs 7610 question

[Doug Person]

It's true that the IC-7610 is simply two IC-7300 type receivers in one 
box. But, it IS dual receive - which is nice. Another impressive feature 
is the built-in web server. Remote control is simple and accessible from 
any PC. Otherwise, it has the features you would expect in a mid-range 
transceiver. And, of course, the K3s maintains the lead in receiver 
performance.

One end's TXD is the other end's RXD. That's obvious to those who have used 
RS-233 for a while but if someone needs to ask then it may not be obvious. Find 
the TXD pin on the source and connect it the RXD pin on the destination.

Sorry about the pin typo.  Look at the cable link for the steppIR that 
Dick K6KR sent and that will be obvious.  I was looking at that diagram 
when I typed my response, but did not proof it.

TXD is really pin 3.

Yes, since you are using both the KXUSB and the KXSER cables, a "Y" at the 
KXPA100 would serve you well.
If your magloop controller also attempts to transmit, you can remove the 
connection to pin 2 on the DE9 end of the KXSER cable (just remove the 
backshell and disconnect the wire).

RS-232 multiplexors are complicated devices and require the use of the full 
RS-232 bus (mainly DTR and CTS signals) to handle the handshaking signals.  The 
3 conductor KX3/KXPA100 wiring will not provide the proper handshaking signals.
The handshaking signals are not provided from the data stream (as they are in 
Ethernet and other communications protocols), but from the explicit signals 
separate from TXD and RTS.

Note that the KX3 (and most other Elecraft products) rely only on TXD and RTS, 
which are reserved for data transmission only in the RS-232 scheme of things.

Steve,

Are you using the KXUSB to connect with the KXPA100/KX3, or are you using the 
KXSER with a real computer serial port or a USB to serial adapter?

Since your magloop controller only 'sniffs', it means it should only listen and 
never try to transmit on the RS-232 signal lines.  If it only listens, there 
will be no collisons (RS-232 is not packet oriented, but an asynchronous 
communications system).

If the magloop controller also transmits on the RS-232 bus, you will need some external 
device to act as "traffic cop" - note that RS-232 is a point to point system 
(unlike Ethernet and others) where there is one driver device and one receiver at each 
end.

So yes, you can use a splitter - one with a 3.5mm stereo plug and two 3.5mm 
stereo jacks if using the KXUSB.
If you are using the KXSER cable instead, yes, you can connect a "Y" DB9 splitter to the 
DB9 end of the KXSER cable - the computer connects to one side and the magloop controller connects 
to the other side of the "Y".

Re: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied

[Jack Brindle via Elecraft]

If you are looking at creating a Y splitter (actually the best way for this 
setup), then be sure to only connect ground and the signal going to the magloop 
controller. 
As someone has mentioned, you do not want to have two devices driving a data 
signal simultaneously. At some point one will go to +12V, the other to -12V. 
They will argue and one will win, the other will cease to function.

We were very careful when designing the devices that need to “sniff” the RS-232 
cable. The KRC2 has an internal multiplexer that allows it to share driving the 
signal to the radio in parallel to the one from the computer.
Even still, we advice folks to set one or the other for sending commands to the 
radio. The KPA500 has an internal relay to enable or disable the data being 
sent out the PC port. this is controlled by the menu system, allowing
the KPA to perform serial polling (PC port TxD will be enabled) or pure 
sniffing (TxD disabled).

Note that enabling both devices (computer and antenna controller) to poll the 
radio can be problematic, even with a multiplexing device. There are some PC 
applications that can be greatly surprised if they receive a response they 
didn’t specifically ask for. The surprise generally ends in a crash. Most 
programs have been rewritten to accept whatever comes there way. I won’t 
embarrass the problematic program’s authors, but they are aware.

There is one other thing to consider. If you always use the radio and magloop 
with the computer running, then you are fine. But at some point if you don’t 
want to use the radio then you will need a source to poll the data. In that 
case just set the radio to output changes as they occur. That should do the job 
quite nicely, keeping the magloop controller happy with more data than probably 
needs to get the job done.

Re: [Elecraft] K3 -> Very Early Acom 2000A

[Dick Green WC1M]

Hi Will,

I have an early 2000A driven by a K3. I'm pretty sure you can just connect the 
Key Out jack on the K3 to the Key In jack on the 2000A, and the hard-coded 
transmit delay in the K3 (5ms?) will be adequate for the vacuum relay in the 
2000A to switch. 

However, if you want to be 100% safe, or if you get key sequencing faults from 
the 2000A, you can use the 2000A key loop. This requires connecting the 2000A 
Key Out jack to the K3 TX INH pin (pin 7) on the Acc jack. Since the 2000A 
pulls Key Out low when it's OK to transmit, you need to pull pin 7 on the K3 
ACC jack  up to 5VDC (max) with a 10K resistor. To do that, you'll have to run 
a line over to the K3 12VDC jack and use a resistor divider or a transistor 
circuit to drop it down to 5VDC (the latter is how I did it.)

I've seen a diagram where someone got the 5VDC pullup voltage by shorting pin 1 
to pin 7 on the Acc jack. Pin 1 is the FSK input, which is pulled up to 5VDC. I 
don't know if this works, but it's simpler than what I described above. I'm 
pretty sure it means you can't use the FSK input.

Once you get the hardware connected, go into Config:TX INH and set INH = Hi. 
You'll need to be in tech mode to do this.
 
Hope this helps.

73. Dick WC1M

Re: [Elecraft] K3S Comparison table finalized (link attached)

[Bob Wilson, N6TV]

Agreed Ken.

This is the only part of the table that seems a bit unfair to the IC-7610.
I've added the missing parts with ">>>" (I hope this formats OK):

*Features*   *K3S* *IC-7610**K3S Benefits*
Spectrum + waterfall
display area   total 7.5”  5.5”   More readable display

>>> Display. res.  P3: 480x272 800x480(IC-7610 better res.)
>>>P3SVGA: 1920x1080  P3SVGA better res.

Marker pointing
mechanism  Dedicated knob  Touch  Accurate marker tuning
>>>or
>>>USB Mouse  (Mouse more accurate)


In sum, even using only part of the screen for the waterfall, the IC-7610
display may be able to use more horizontal pixels than the P3, so it can
show more signal lines.  But the Icom waterfall display doesn't scroll in
Fixed mode (the VFO A cursor just goes off screen), which is a major flaw
in Icom's design, not to mention the complex menu settings required to
adjust the waterfall span and edges.

Yes, the P3 dedicated knob + markers may be more accurate than touching the
Icom screen, but using that tiny P3 knob is really much more difficult than
clicking on a signal with an SDR, or just moving the VFO knob.  However,
the IC-7610 does let you connect a USB mouse.  Then you just click on
signals with the mouse pointer on the screen, so Icom wins on that.

However, I'm told that the scroll wheel on the mouse doesn't "fine tune"
the Icom VFO position after you click, so they really missed the boat on
that one.

Again I beg for the P3's USB connector to add mouse support.  The hardware
is all there.

Left click:Move VFO A
Right click:  Move VFO B
Scroll Wheel:  Fine tune VFO A, B, or last-clicked (user option)

Re: [Elecraft] K3 -> Very Early Acom 2000A

[Chuck, AE4CW]

In addition to a coax connection, the simplest approach is to hook up a key 
line from the Key Out on the K3 to the Key In on the Acom 2000A.  Then, simply 
use a single "dit" (enable SSB+CW in the CW WGHT menu) to cause the amp to 
auto-tune on your current frequency.  You can also issue a short vocal sound, 
and the amp will auto-tune.  There are a few software packages that can listen 
to the K3 CAT frequency changes and send them to the amp, but I think they are 
more trouble than they are worth; it also requires a "special" serial cable.  
You should also set your K3 tune power to 15 watts which is what the 2000A 
expect if you wish to set a customize tuning solution for a particular band 
segment. 

That's all you need to be up and running.

P.S. The new 2000A Remote Control Unit can connect directly to the K3 to listen 
for frequency changes and automatically retune the amp for the new band segment 
(no SW needed).

Re: [Elecraft] KX3/fldigi/USB sound card

[Don Wilhelm]

Brian,

VFO Scanning should happen only if Scanning is turned on in the menu. 
That has nothing to do with the mode selection - scanning can take place 
in any mode.


The main reason for using DATA A is that compression is set to zero, the 
equalization is set flat, and in the K3/K3S you can set MIC SEL to LINE 
without interfering with whatever you have set for SSB settings.

Re: [Elecraft] KX3/fldigi/USB sound card

[Don Wilhelm]

Wunder,

PTT via CAT command does not require any extra wiring, it uses the 
RS-232 control cable to provide the command listed in the K3/KX3 
Programmer's Reference to activate Transmit.  It works well with the K2, 
K3/K3S, KX3 and KX2.


Quite different than using the 'one transistor keying device' on the DTR 
or RTS signal lines.


I use PTT via CAT command successfully on all my Elecraft rigs, and no 
other wiring is required.


Yes, you can use VOX on the K3/K3S, KX3 and KX2.  The VOX on the K2 will 
not provide reliable transmit triggering.

Re: [Elecraft] K3S & PC Win10 Soundcard

[Don Wilhelm]

Joe is entirely correct about this.  Anytime you add a soundcard, 
Windows will try to make that new one the default card.  That means that 
system sounds will go out through that soundcard you just added.  That 
goes for the internal USB AUDIO CODEC in the K3S or any other USB 
soundcard as well.


So when adding any soundcard for digital modes, check to be certain it 
is NOT the default soundcard after it is installed.


Windows does not know about those of us who use soundcards for purposes 
other than playing music and making the Windows Beeps.  They assume that 
we are all consumers who want to listen to our music through the new 
soundcard - that serves the majority of their customers, but not those 
of us who have a different purpose.

Re: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied

[Don Wilhelm]

Steve,

Yes, since you are using both the KXUSB and the KXSER cables, a "Y" at 
the KXPA100 would serve you well.
If your magloop controller also attempts to transmit, you can remove the 
connection to pin 2 on the DE9 end of the KXSER cable (just remove the 
backshell and disconnect the wire).


RS-232 multiplexors are complicated devices and require the use of the 
full RS-232 bus (mainly DTR and CTS signals) to handle the handshaking 
signals.  The 3 conductor KX3/KXPA100 wiring will not provide the proper 
handshaking signals.
The handshaking signals are not provided from the data stream (as they 
are in Ethernet and other communications protocols), but from the 
explicit signals separate from TXD and RTS.


Note that the KX3 (and most other Elecraft products) rely only on TXD 
and RTS, which are reserved for data transmission only in the RS-232 
scheme of things.

Hi Don:

Yes - it occurred to me after sending the post that I might be able to create

KXPA. It is the KXUSB that presently has no place to connect to.

So - I think I can try a 3.5mm stereo y-junction at the KXPA. Hopefully 
impedances won't be an issue at 38400 baud...

I did look for RS232 multiplexers - they seem to exist for industrial

Anyway - thanks for the pointer :)

Steve,

Are you using the KXUSB to connect with the KXPA100/KX3, or are you using the 
KXSER with a real computer serial port or a USB to serial adapter?

Since your magloop controller only 'sniffs', it means it should only listen and 
never try to transmit on the RS-232 signal lines.  If it only listens, there 
will be no collisons (RS-232 is not packet oriented, but an asynchronous 
communications system).

If the magloop controller also transmits on the RS-232 bus, you will need some external 
device to act as "traffic cop" - note that RS-232 is a point to point system 
(unlike Ethernet and others) where there is one driver device and one receiver at each 
end.

So yes, you can use a splitter - one with a 3.5mm stereo plug and two 3.5mm 
stereo jacks if using the KXUSB.
If you are using the KXSER cable instead, yes, you can connect a "Y" DB9 splitter to the 
DB9 end of the KXSER cable - the computer connects to one side and the magloop controller connects 
to the other side of the "Y".

frequency information, allowing re-tuning on the fly. This leaves no RS232 port 
left for remote control of the radio.
How do I modify this arrangement to add an extra serial port for KX3 control? 
My first thought is that, since the antenna controller just sniffs for data, I 
could add a DB-9 Y-cable to provide the extra port at the controller serial 
port location. However, packets could still collide ...does the protocol handle 
this? Is there some sort of multiplexer available?

Re: [Elecraft] KX3/fldigi/USB sound card

The mic plug is shorting the extra contacts on the mic jack. These are used for 
PTT and for Up/Down.

You can disable that in the menus with MIC BTN OFF.

Or, you can use a stereo to mono splitter cable. The mic plug would go into the 
right channel. The left can be used for PTT.

First, make sure the soundcard cables are fully plugged in (give them a

As an immediate workaround, first change the KX3 menu MIC BTN to OFF,

Re: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied

[Stephen Rector via Elecraft]

Hi Don:

Yes - it occurred to me after sending the post that I might be able to create 
the split at the KXPA with a stereo Y-cable/connector. I am using a KXUSB to 
the computer, with a KXSER cable going from the the antenna controller to the 
KXPA. It is the KXUSB that presently has no place to connect to.

So - I think I can try a 3.5mm stereo y-junction at the KXPA. Hopefully 
impedances won't be an issue at 38400 baud...

I did look for RS232 multiplexers - they seem to exist for industrial 
applications. The documentation seemed to be sparse on the web.

Anyway - thanks for the pointer :)

73,

Steve NU7B

Re: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied

[dick]

Typically "sniffers" don't have the TX side connected.  RS-232 can't have
multiple transmitters on either wire.

This is done with SteppIR controller, for similar reasons.  SteppIR
describes a splitter cable for DE-9 connectors. The same principle (with a
much simpler cable, just tip and ring) applies to the 3.5mm connector to the
KXPA100.

Re: [Elecraft] [KX3] RS232 xcvr control when serial ports are occupied

[Don Wilhelm]

Steve,

Are you using the KXUSB to connect with the KXPA100/KX3, or are you 
using the KXSER with a real computer serial port or a USB to serial adapter?


Since your magloop controller only 'sniffs', it means it should only 
listen and never try to transmit on the RS-232 signal lines.  If it only 
listens, there will be no collisons (RS-232 is not packet oriented, but 
an asynchronous communications system).


If the magloop controller also transmits on the RS-232 bus, you will 
need some external device to act as "traffic cop" - note that RS-232 is 
a point to point system (unlike Ethernet and others) where there is one 
driver device and one receiver at each end.


So yes, you can use a splitter - one with a 3.5mm stereo plug and two 
3.5mm stereo jacks if using the KXUSB.
If you are using the KXSER cable instead, yes, you can connect a "Y" DB9 
splitter to the DB9 end of the KXSER cable - the computer connects to 
one side and the magloop controller connects to the other side of the "Y".

this? Is there some sort of multiplexer available?"


If only one device is doing the interrogating then there cannot be any conflict 
and there is nothing to multiplex. Typically the listening device will only 
need a 2 wire interface (TXD and GND). My KPA500 just listens to my TS-590 
responses to Omni-Rig. Multiple receivers can listen to an RS-232 transmitter, 
just be careful not to try to make a TX talk to a TX and that may happen if you 
make a poor choice of Y cable.

With Windows you *MUST* set up the sound cards before starting your
apps (WSJTX and JT-Alert) as the sound card assignments change every
time a sound card is added or removed.

Your symptoms indicate that WSJTX is configured for the default audio
device (or only audio device if the "BT RXr" is not connected).
Connect all of your audio devices, configure the default output device
with (Windows) Sounds -> Playback -> "BT RXr" as the default device (and
default communications device).  Configure the default input device
with (Windows) Sounds -> Recording -> "Logitech mic" as the default
device (and default communications device).

Once the defaults are assigned - *without adding or removing audio*
*devices*, start WSJTX, select File -> Settings -> Audio and make
sure Input: "mic (USB Audio CODEC)" (Left) and Output: "speaker (USB
Audio CODEC)" (Left).

After that, start JT-Alert, Select Settings -> Manage Settings ->
Sound Card and set "The Sound Card used to play the audio alert
(wave) file to "[0] Windows Default Sound Card".

If *at any time* you change the sound card(s) attached to your
computer (including the K3S/K3 with KIO3B) you will need to close
WSJTX and JT-Alert, reassign the default devices, restart the
applications and reconfigure their audio devices.  The devices *may*
keep their (device numbers) assignments but they may not - and will
*most certainly not* if the a new device has been added or a device
has been removed.

I should clarify my statement on TX when the BT RXr is plugged into the from
Headphone jack - when WSJT-X is set to TX Enable and the K3S TX Red LED
illuminates, but ALC bars are absent (0 bars).

The Headphones jack is set as default and appears as Location 0 in High Def

(0) default device.

In JTAlert, the soundcard Test works and I hear audio alerts in the BT

Worth trying the rear PC soundcard jack?

Re: [Elecraft] KPA1500 install on side

I've run my PS on the side. No issues there. I assume you could run the RF
deck on it's side, although the controls would looks a bit odd in my
opinion. 

Do you really want your RF to be 90 degrees out of phase?

Re: [Elecraft] a question to Wayne Burdick - K3S if gain

[Don Wilhelm]

The filter gain settings are only the suggested starting points, and 
will work if your particular filters are "average", but in fact the 
optimum setting will vary from filter to filter.


One method for determining the proper gain to use is to use the gain 
metering in the K2 itself and a signal generator.
You will be using AFV and dBV in the Alternate VFO B display.  See page 
38 of the K3S manual.  Be sure to turn Tech Mode ON in the configuration 
menu.


Turn AGC off and center the signal in the narrowest filter (in CW mode).
Then go to the widest filter. (stay in CW mode)
Set the audio gain for a comfortable level and look at the K3S AFV - 
wait until it settles.  Do not readjust the AF gain until finished.

Change the VFO B display to dBV - it should read zero dB.
Now switch to FL2 and again note the dBV value - if it is also zero, you 
already have the correct FLx GN value set.  If not zero, make note of 
the dBV value and do the same with FL3.


Once you have the dBV readings from the procedure above, you may go into 
the CONFIG:TXx GN values up or down by the dBV values you measured.


This procedure is indicated on page 40 of the K3S manual, but I believe 
I have provided more detail.


For setting the AGC for your K3S, you might want to look at the 
information contained in the "Noisy K3" article on my website www.w3fpr.com.

KE7X, Fred Cady also has some information on his website.

I need an info, and this time I thought "why not ask to the Elecraft nr.1 top
tech?"
If it is possible.
On my Elecraft K3S, sn 10715, the if gain, or better the FLx GN, was setted
0 for FL1 (2700hz-5 pole),
4 for FL2 (500hz-5 pole) and 8 for FL3 (200hz-5 pole).
I read somewhere that it would be better 0 for wide filter, 2dB for medium
filter, 4 dB for narrow filter.
What is better Wayne? Can I use on my great K3S 0dB-2dB-4dB? Or you prefer
other settings?

Re: [Elecraft] K3S & PC Win10 Soundcard

[Don Wilhelm]

Bret,

If you look at the soundcard in the Windows Sound properties, what us 
listed for output when only the K3 is connected? (Likely Speaker)  Then 
plug in the BT RXc - is the same output still listed and the headphone 
added, or did Speaker get replaced with Headphones?


Some soundcards will not allow simultaneous Speaker and Headphone use.
Usually when the front panel jacks are used, the rear jacks are turned off.

WSJT-X does not use the soundcard path for TX enable, but the serial 
port connection.


Apparently your BT RXc is turning off the audio to the K3 for some 
reason - this is a computer audio path problem, not a K3 problem.

The Headphones jack is set as default and appears as Location 0 in High Def

In JTAlert, the soundcard Test works and I hear audio alerts in the BT

Worth trying the rear PC soundcard jack?

The K3 manual provides 0/2/4 as suggested values.  The filters in your
radio, as determined by the factory calibration procedure, must have needed
more gain.

What is better Wayne? Can I use on my great K3S 0dB-2dB-4dB? Or you prefer

You can change the Flx gain values and hear the sensitivity of each filter
go up and down.  Ideally, signal strength should not change as you switch
between filters.  The K3 Utility provides an RF Gain calibration procedure
too (requires a signal generator).

How can one define "best AGC?"  Define "more pleasant."  Maybe you can post
an audio recording made from the headphone jack with an isolation
transformer so that we can hear what you're hearing.

Have you tried changing the K3's AGC settings from the factory defaults to
the values recommended here

?

As for QSK, T/R turnaround time is probably better in the Swan rig because
it doesn't have any digital signal processing, so no latency added, so no
delays waiting for buffers to fill before the receiver hears signals
between elements.  But no DSP means limited noise reduction, limited notch
controls, no adjustable noise blanker, etc.  You can't have everything.

Re: [Elecraft] Trouble Downloading KPA1500 Utility

[Rick WA6NHC]

When Norton quarantines a file or deletes it, it usually gives you a pop 
up that allows you to see what action was taken.  The user should click 
on that to bring up the security panel for that file, then tell Norton 
to 'trust' it and undo what it did.


The other option is if you can download the file and before Norton scans 
it (as in extracting from a zip), you right click on the file, go to the 
Norton file area and within that you can also tell Norton to ignore that 
file.


Failing those, you can have someone email the file to you (zip) and tell 
Norton that it's allowed.

Re: [Elecraft] K3S Comparison table finalized

[Charlie T]

 I think the comparison of the K3S to the IC-7610 is just slightly unfair on
strictly a cost comparison.
First, I will say that I own both radios, so I'm not "drinking the Kool-Aid"
for either one.
I like them both and use them equally.
 The IC-7610 can be had now, even without the $200 "Dayton Discount" for
about $3.2k
A similarly equipped K3S even in kit form is well over $5k, including the
P3/VGA required to make the proper comparison, but NOT counting any extra
filters you may want.

Please note, I am NOT arguing on the basis of ultimate performance, but
simply cash outlay for similarly equipped radios.
And yeah I know a TS-520 sounds great and will do all a casual op will need
and, can be had for less than the "Dayton Discount" itself.

I like the operating logistics of the Icom over the K3S, but the Elecraft
works better AND has more features even though some are buried in multiple
menus which is also a requirement due to the lack of panel space.  Elecraft
does the best to wring out multiple functions from one controlpunch,
hold to 1 sec, hold for 3 sec while standing on one foot etc.

Icom's touch screen really IS easy to like, even though I thought I'd hate
it.

Being a ¾Centurion, these are probably the last radios I'll buy anyway, so
WTH. "Live long and prosper" as the saying goes.

73, Charlie k3ICH

[Elecraft] a question to Wayne Burdick - K3S if gain

[IK4EWX]

I need an info, and this time I thought "why not ask to the Elecraft nr.1 top
tech?"
If it is possible.
On my Elecraft K3S, sn 10715, the if gain, or better the FLx GN, was setted
0 for FL1 (2700hz-5 pole),
4 for FL2 (500hz-5 pole) and 8 for FL3 (200hz-5 pole).
I read somewhere that it would be better 0 for wide filter, 2dB for medium
filter, 4 dB for narrow filter.
What is better Wayne? Can I use on my great K3S 0dB-2dB-4dB? Or you prefer
other settings?
C op 99% of time...


Second and least question for Wayne. 
Sometime I like to use my old Cubic Astro 102BXA, yesterday on 10 meters,
with a bug. 
How can be that this rig, 35 years old, have the best agc and a great qsk
even for today standards?
Lot better than every ja rigs, but even more pleasant to listen than today
greatest rigs in the world (Elecraft obviously)
Can it be that audio derived agc (I think it have this kind of agc) is the
best even today?
