[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,
   Whew, 40 meters was noisy and copy was difficult.  Even Brian was 
weak today at 559.  The QSB was not helping matters on either band. But 
20 m was much better than 40 m.  It may be time to move the 40 meter net 
back to where it was at 0100z.  I'll wait one more week and try it again 
at z.


  On 14050 kHz at 2200z:

W0CZ - Ken - ND

K4JPN - Steve - GA

K6XK - Roy - IA

AB9V - Mike - IN

KB5RF - Tom - TX


  On 7045 kHz at z:

K0DTJ - Brian - CA

K4TO - Dave - KY

Are the only two I am very sure of.

KB5RF may have called but became ESP quickly.

I don't think the other two were talking to me at all :)  Oh well, 
that's how it goes.  I heard K4TO on the initial call up but not once 
again after that.



Happy Easter to all,

    73,

    Kevin.  KD5ONS

Re: [Elecraft] Elecraft KX3

[GRANT YOUNGMAN]

Did you pull the rubber cover off the knob?  There’s a hex screw under there.  
It may have loosened enough for the knob to slip up on the shaft far enough to 
be free wheeling.  You can adjust the tension by pressing the knob closer to 
the case..

Re: [Elecraft] KPA500 power supply

[Augie "Gus" Hansen]

I don't understand this Joe. The KPA500 has an internal PS. A separate 
Astron PS serves no purpose for the amp. Do you mean both the amp and 
the rig+PS are on the same circuit?

Re: [Elecraft] KPA-1500 s/n 56

[Bill Johnson]

You might try removing the USB connector, Restart, check the device manager, if 
a device isn't linked, remove it , then plug in the USB.  If that doesn't 
connect, remove it again, and then sort through the comports in the utility and 
if that doesn't work, you may have different problem.  I suspect your issue is 
within your PC not the amp.  Let me know.

Hi Bill,

Thanks for the reply.

I'm using Windows 10 Pro, Windows Defender.

I thought that you had nailed it.  I checked the Allowed Apps in Windows 
Defender and the KPA-1500 Utility wasn't listed.  I added it and restarted the 
computer, no help.  Shouldn't I hear a notification sound when I plug/unplug 
the KPA-1500 USB cable.  I do when I unplug/plug the keyboard.

Thanks again, Ed

Re: [Elecraft] KPA-1500 s/n 56

[Howard Stephenson]

Ed,

Can you connect the K3 Utility to your K3S using the USB cable supplied
with the K3S?

If not then it sounds like you have a FTDI driver issue.
http://www.ftdichip.com/Drivers/VCP.htm
http://www.ftdichip.com/Support/Documents/InstallGuides.htm

If the K3S connects to the K3 Utility then please send an e-mail to <
supp...@elecraft.com> letting them know your KPA1500 USB issues.

Re: [Elecraft] KPA-1500 s/n 56

[Ed Gilliland]

I replaced the USB cable with a known good cable, no help.

I am using the K3s.  I neglected to order the AUX cable when I ordered 
the amp but since have placed one on order and should be here tomorrow 
but I don't think it will help in this case.


Maybe Elecraft Support will have an answer.  I REALLY don't want to send 
the amp back to Elecraft.

Any spare USB A to USB B cables around that you can try?  Might be something as 
simple as a cable.

Failing that, support is your best shot.

I'm almost positive that the USB port is used during manufacturing testing for 
the burn-in process that exercises all amps before they leave Watsonville, so 
at some point it was working, at least with their cables, their computers and 
their device drivers.

Are you using a K3S?  Can it be reached with the same USB cable?

Sorry!

Re: [Elecraft] K3: ModMic boom mic

[charlie carroll]

Ed:
Also spend some time with the TX EQ settings on your K3.  I had the help 
of a couple friends who know my voice very well.  I don't remember the 
exact numbers but the 2 or 3 low frequency bands were rolled off a bit.


I've used this mic in various contests for about 3 years.  Always get 
positive comments about excellent audio.

An off-the-shelf stereo to right/left splitter should do the job. That puts the 
buttons (logic bias) on one channel and leaves the mic and mic bias on the 
other.

[Elecraft] K2 Shuts Down Immediately after Turning Power Switch On

[Michael Eberle]

I hooked up my K2 this morning and everything seemed to be working 
fine.  I have the K2/10 with the KAT2 in one box.  I built the KAT100 
and KPA100 in the EC2 enclosure.  With the K2/10 connected to the 
KPA100/KAT100, I hooked up an antenna and initiated a TUNE on 40 
meters.  It started tuning and in the middle of the tune, everything 
shut down as if I had turned the power swtich off.  I tuned the power 
switch off and back on again and now it will only power up for about a 
second and immediately shut down again.  I disconnected the K2 from the 
KPA/KAT box and with nothing connected but power to the K2/10 it still 
does the same thing.


I disassembled it and checked Q7 and Q8 which do not appear to be 
shorted.  The collector voltage on both initially reads 10.8 volts at 
power up until it shuts down and then drops to about 0.8 volts.  The 
base voltage on both of them is at about 0.55 volts.


Where should I go from here?

Thanks,

Mike - KI0HA

[Elecraft] power varying - KPA1500

[Carl Yaffey]

When running the KPA1500 at full power, sometimes the power will fluctuate. 
EXAMPLE: I was checking in to the Elecraft SSB net a little while ago. While 
transmitting, the power dropped to around 400W. This has happened on 20M CW as 
well. I wonder if the K3S output is dropping. (??). 
If I run at 500W or so, no problem.

I’d suggest using the Windows Device Manager to view COM ports, see what COMn

change, it might be a device driver needed. Usually Windows finds this driver 
automatically if needed, but sometimes you need to reinstall the driver. There 
is a link to the FTDI driver website on the page for KPA1500 Utility. There may

The USB port is used for factory burn in software, so it was working at least

[Elecraft] AA and AAA NiMH Battery Charging

[Bob DeHaney]

There are chargers available which will do a controlled current re-charge
and let you match the battery voltages.   They are not cheap and not found
at your local electronics emporium.  As I recall, I paid about $55.00 for
mine.  I have one from a small German factory; it has an LCD for each
battery and gives various useful info about each battery.  It does give up
on some but saves a lot of others.  For me it was worthwhile; there are lot
of AA and AAA batteries in our household besides Ham Gear (GPS Receiver,
High powered camera flash, grandkid's toys, telephones, LED flashlights,
etc.).

If you want to run a multi-multi single op station simply time jump 
repeatedly into the contest period from any other time during the year 
(or century for that matter). Run stations for two hours and then rest 
in another time. It will keep you fresh for those 500 Q/hr runs. Since 
you will be well rested you can rack up extraordinary scores. The 
standard liquid nitrogen cooling system is able to dissipate the waste 
heat from the 25 Petawatt fusion reactor under normal use. Liquid 
helium cooling systems are available on special order. Antigravity 
mods let you take the KX19 on camping trips, ocean cruises, or even 
pedestrian mobile. The additional 5 Petawatt power source for the 
antigravity modules necessitates the liquid helium cooling module. 
Call Elecraft today for a quote.


/Time displacement of 1957 ionospheric conditions is frowned upon by 
most reputable contesters. Modifying the fusion reactor voids 
Elecraft’s warranty. It may eliminate small sections of the continent 
too. Alterations to the time displacement circuitry also voids the 
warranty and may permanently place the user in another time stream. 
Each use of the KX19 envelops the operator in their own pocket 
universe to minimize the time paradox problem. Avoid having more than 
two KX19 transceivers operating in close proximity. There is a slight 
danger of forming a black hole when there are three running in one 
room. If you experience a gravitational anomaly evacuate immediately 
and wait for a few hours before returning. The micro black hole will 
have evaporated by then./

Yep. The KX3 is also highly compatible with external battery packs, 
something as simple as six AAs in a holder that plugs into the power jack.


LiFePO4 packs sold by Bioennopower have also become quite popular. They 
come in a wide range of sizes/capacities, and are much lighter weight 
for the capacity they provide. For all day 100w operationat a rare 
mountaintop 6M grid that is in deep shade and requires a 3 mile hike up 
a 1,000 ft trail, several of us have bought 20Ah batteries, cost about 
$200 and weighs 5.5#. Much smaller packs are available. A 3 Ah pack 
costs $50 and weighs 13 oz.


Remember that the KX3 draws less current for the same power output when 
run from a higher DC voltage, and LiFePO4 batteries provide 13-14V for 
most of their discharge curve.

Re: [Elecraft] Who's On First?

[Bob Wilson, N6TV]

Yes, according to the Release notes (hfwnotes.rtf):

*MCU 5.33 / DSP 2.86 / FPF 1.23, 8-3-2015*

* PTT/KEY USE WITH THE USB PORT IMPROVED:  PC applications can activate PTT
and KEY at the K3S via the USB port's RTS/DTR signals. However, initial
setup of the rig's USB port by the PC may cause pulsed or continuous
activation of the transmitter. This can happen if the computer is turned on
after the K3S, or if the USB cable is not connected. There is now a "Safe"
mode (the default) which disables PTT-KEY transmit until the K3S receives a
command via USB, such as a read of the rig's VFO frequency. To turn on safe
mode on/off, go into CONFIG:PTT-KEY and tap '1' to select "USB SAFE" or
"UNSAFE". Exit the menu and turn the K3S off/on. Applications that use
PTT-KEY via USB but never send commands may require "UNSAFE" mode. In this
case, unwanted transmit can be avoided by turning the PC on before the K3S.

* CANCELLING UNEXPECTED PTT-KEY ACTIVATION:  If an external source (usually
a PC) activates PTT or KEY unexpectedly, you can cancel transmit by tapping
the XMIT switch. This will show ERR KEY or ERR PTT on VFO B. Once the PTT
or KEY source as been removed, transmit will be re-enabled. If the cause
may be unneeded PTT-KEY activation via the USB port, go into the
CONFIG:PTT-KEY menu entry and set the parameter to OFF-OFF.


However, if use an FTDI USB-to-Serial adapter on Windows with other
Elecraft radios or devices, the FTDI drivers provide an easy way to disable
the search for a serial mouse or legacy analog modem on the serial port,
and this prevents unwanted RTS/DTR "key down" activation at boot time.
This works with recent KUSB adapters or homebrew external CW or FSK keying
circuits on virtual serial ports that may be connected to your radio (K3,
K3S, KX2, KX3, etc.).

   1. Open the Windows *Device Manager* (shortcut:  Windows Key +  R
   (run):  devmgmt.msc)
   2. Expand *Ports*
   3. *Right click* on the virtual COM port defined by the FTDI
   USB-to-Serial Adapter
   4. Click *Properties*
   5. Select the *Port Settings* tab
   6. Click the *Advanced...* button
   7. Under *Miscellaneous Options*:
  1. Uncheck *Serial Enumerator* (default is checked)
  2. Check *Disable Modem Control at Startup* (default is unchecked).
  This should be the only option in the list that should be checked.
   8. Click *OK* to close the Advanced Settings dialog
   9. Click *OK* again to close the Serial Port Properties dialog

As far as I know, only FTDI's USB-to-Serial drivers provide options to
disable this legacy behavior on Windows that causes RTS/DTR to be activated
at boot time.

[Elecraft] The new KX19

[kevinr]

Announcing Elecraft’s super secret KX19 with Time Displacement Circuitry 
(patent pending).



If you want to run a multi-multi single op station simply time jump 
repeatedly into the contest period from any other time during the year 
(or century for that matter). Run stations for two hours and then rest 
in another time. It will keep you fresh for those 500 Q/hr runs. Since 
you will be well rested you can rack up extraordinary scores. The 
standard liquid nitrogen cooling system is able to dissipate the waste 
heat from the 25 Petawatt fusion reactor under normal use. Liquid helium 
cooling systems are available on special order. Antigravity mods let you 
take the KX19 on camping trips, ocean cruises, or even pedestrian 
mobile. The additional 5 Petawatt power source for the antigravity 
modules necessitates the liquid helium cooling module. Call Elecraft 
today for a quote.


/Time displacement of 1957 ionospheric conditions is frowned upon by 
most reputable contesters. Modifying the fusion reactor voids Elecraft’s 
warranty. It may eliminate small sections of the continent too. 
Alterations to the time displacement circuitry also voids the warranty 
and may permanently place the user in another time stream. Each use of 
the KX19 envelops the operator in their own pocket universe to minimize 
the time paradox problem. Avoid having more than two KX19 transceivers 
operating in close proximity. There is a slight danger of forming a 
black hole when there are three running in one room. If you experience a 
gravitational anomaly evacuate immediately and wait for a few hours 
before returning. The micro black hole will have evaporated by then./

[Elecraft] "Bat Err" on KX3 - follow-up

[Dauer, Edward]

Several replies suggested I check the voltage of the NiMH batteries as a first 
step.  Did so this morning, with an interesting result.   Of the eight (all are 
2700 mAh Powerex NiMH 1.2 v nominal), the mean voltage was less than a half 
volt (0.45 VDC); the median and mode were each less than one tenth of a volt 
(0.06 VDC.)  The best of them was only 1.23 and 5 of them were at 0.06 VDC or a 
bit less.  So much for advertised shelf life.  Seems that the KX3 draws some 
trickle current even when turned off.

It might be they could be resuscitated with another charger, but Don Wilhelm 
wisely cautions against it.  With this deep a discharge, the charging current 
could be excessive without having a constant-current lab-type charger, which I 
don’t have.  Best to just replace the whole bunch.

Of course I would learn this on Easter morning, when there are none for sale 
anywhere nearby.

If replacing all eight doesn’t fix the error message I’ll post again with 
another plea for ideas.  Thanks, all, for the advice; have a great holiday 
weekend.

Ted, KN1CBR

Re: [Elecraft] Migrating a KPA3 POWER module to a K3S

[Ian White]

> Then at some point, you just need a K3S.

Not quite: you would also need a new KPAIO3A interface board - and
even then, it would only be a partial upgrade. 

My very early K3S/10 was probably the first to undergo a
comprehensive 'module migration' in the wild (5000 miles away from
the factory). Elecraft's support was exemplary - as ever - but we
discovered that the older KPAIO3 does not function correctly with
the K3S mainboard. It does not correctly control the relays and the
fans, so it fails the PAIO TST procedures. When the KPAIO3 is
replaced by a KPAIO3A, then the KPA3 does become compatible with the
K3S and will function much the same as it did in the K3. 

But migrating a KPA3 into a K3S can only ever be an *incomplete*
upgrade. As Joe has already pointed out, it does not include many of
the other improvements that Elecraft made in this area of the K3S -
not only the increased number of power pins but also the KPA3A
itself, which is a completely new design using power MOSFETs. 

So even though it is possible to migrate a KPA3 into a K3S, the
result can never be a true K3S/100. Therefore it isn't surprising
that Elecraft does not recommend this procedure, and does not offer
it as part of the factory migration service.
