Hi Curt,
Do you have the internal ATU in your K3s?
If so, disable it by putting it in Bypass mode
and repeat your experiment.
Does the Forward power meter show any
output power, and can you confirm the
actual output power with an external power
meter?
If you still have a very high SWR into a
With a verified good dummy load and on any/all bands, using antenna one or
antenna two, I have a SWR reading of 99.9. I see no charred components.
It has not had a lightning strike Newest download has been installed. Can
anyone provide insight or direction for a solution?

Hi Jerry,
First, a couple of questions:
-- does the abrupt loss of power occur if you operate
with the TX PWR set to less than 12 watts on
15 meters? This engages only the low power
driver amplifier and takes the 100 watt PA module
out of the picture.
-- if you're operating on 15 meters at the

only and run it at 75 - 85 watts. It has a new problem on 15 meters only.

Perhaps it is still on transmit. A leaky USB-Cable is picking up RF and
hold the PTT.
Just an idea...

I have had my K3s since January. I use it exclusively on CW. Twice in the
past ten days, in the middle of a QSO, I can hear nothing when I stop
sending. No background noise. No signal. The quick fix is to turn the
unit off, then right back on.
There is at least an inch of cooling all around
I contacted Elecraft Support as advised & Doug suggested I re-seat the
filters in the main board & the Sub Receiver.
Lo & behold,... the problem disappeared and audio from all filters is now
normal!
Thanks Doug

My two narrowest filters have CONFIG -> FLx GN set to 6dB as opposed to
0dB for the others. Press the number keypad to select the appropriate
filter.

I doubt that there is anything else wrong. Each filter will vary in its
gain (actually loss) amount. The 4 dB stated in the menu listing for
the 400 and 250 Hz filters is only a starting point.

I had done that Don as per the Manual - 1-2dB for 400Hz & 3-4 dB for the
250Hz filter.
To get the right level of loudness I have had to add the max ie.8 dB. So, is
something else wrong?

Ray,
You can set the gain parameter (FLxGN) parameter in the menu to
compensate for that. Either use K3 Utility or set it manually in the
CONFIG menu.

I have recently fitted a Sub Receiver & some additional filters to my new to

In the sub RX there is a 2.8K, 2.1K, 0.7K, 0.4K & 0.25K. I have a problem

Don’t you hate it when the culprit is so simple?
Glad you found it.

I have been using my K3S on WSJT-X without any problems. Today, the frequency
appears to have shifted .7 KHz low. That is, if I were on 50.313 MHz FT8, I
now have to tune to 50.3137 to decode signals.
I would appreciate any suggestions.
Thanks,
