Perhaps one of the modern Android or Iphones has an application that will

The first thing that comes to mind is that a strait key has something
on top of it, but I sure you checked that. Is it possible that there
is a short in a keying circuit or maybe a foot switch that has
something on it or is shorted out while the rig is set in the CW
mode?
I don't
Tom,
You will have to begin lifting resistors and inductors if you cannot
find a solder bridge by inspection. If you end up doing that, do it in
an orderly fashion and keep notes as you work - in the heat of
troubleshooting often the thought comes up which says did I try that
already? -

Google Play has a number of these, some free,
check out SMTR MD in the manual
(Advanced) S-meter mode: When set to NOR, preamp/attenuator on/off will
affect the S-meter. (The default values of SMTR OF and SMTR SC apply to

Buck,
If indeed the finals are heating while the K3 is truly in receive mode,
then that would indicate either the PA finals have 'turned belly up' or
that there is a failure in the bias circuits that is turning the PA
transistors on.
First unplug everything from the K3 except for a dummy load.
Jay,
Normally, the preamp and attenuator will change the S-meter reading. If
you do not want that to happen, go into the menu and change to SMTR
ABS. I suggest (contrary to the manual suggestion) that you calibrate
the S-meter with the preamp and attenuator both off before setting SMTR
Luc,
I really cannot tell whether you have a K3 problem or an antenna problem

If you have access to a signal generator with a 50 uV output (Elecraft

Don - thanks
If I let it sit while turned on, the fan will bring the temp down, then
I can turn the power back up and operate at 100w. The fans keep the PA
temp around 45C. So I don't think the finals have gone - yet.
It is drawing about 2 amps with the power turned off but plugged in and

Hi
I noticed the same behaviour recently as we'll.
In addition, it appears that sometimes the p3 will not issue a qsy either
from the hardware or via software either.
It seems to happen when there is a fair bit of rs232 activity to the k3.
Ill look at this in more detail in the next couple of days
I've only had my KPA500 for a couple of weeks. It seems to have so much
gain that adjusting the K3's power control takes a very fine touch to drive
the amplifier to the desired 500W without overshooting. It's too easy for
me to add 50W of KPA500 output when I really want, say, 10w or 20W, but

Jim,
If you want more precise power control at levels below 100 watts, why
not put the KPA500 into standby?
The KPA500 has approximately 15 dB of gain, so the resolution in power
output is 15 dB (31.62 times) worse than the power resolution on the 100
watt K3.
With the KPA500 in standby,

Mine isn't at all sensitive and once set, I never really touch it. One

Hi all.
I finally broke down after a few years of K2 envy and ordered a K2/10 with SSB,
NB and 160M.
I'm part way through building SN 7438 and have run into a problem.
I'm trying to fit the front panel board to the front plate and am having a fit
problem.
There are 3 short round spacers
Hi Dale, thanks for the answer.
Yes, I was very careful to make sure all of the switches were soldered with the
spacer underneath them.
The front panel board rocks on what appears to be the led bargraph.
I checked the height of the bargraph and it's about 1.5 mm higher than the LCD
freq.
No worries, thanks a lot Dale.
I've put down the soldering iron and solder wick and will wait a while.
