Martin,
Contact Elecraft support. I purchased a pair of the same MOSFET's a
couple of years or so ago when my K3 did the same as yours...
Unfortunately mines done it again just recently, so this time I'm ordering
a few spares.

Hi,
Both output devices in the LPA, Q4 and Q5, RD15HVF-1, show low ohms gate
to source, one is 2.4 ohms the other 4.6 ohms.
Anyone have a recommended source? I don't think these are available
locally, I'll need to get a couple shipped in from US or elsewhere most
likely.
Thanks
Martin, HS0
Have you tried doing a TX GAIN calibration? It will likely fail given what you
are seeing but it's another step to try.

Hi,
I can see output at the XVTR OUT jack. Using direct input on the LP-100A
meter it shows output varyng in sympathy with the output level control
and a setting of L 1.00 gives pretty much 1dBm on the LP-100A. Lowest I
can read is around -12dBm and highest about +3dBm before the K3 switches
, then there is something wrong in the DC power to the amplifier
stages.

Hi,
Well I've been through all of the operational settings. CONFIG : TUN PWR
is set to NOR and I can vary the power with the power control but the
output meter display stays at 0.0 and the VSWR displays only - - . I had
a settings save from about a month ago but uploading that hasn't changed
Had the same thing happen here to my K3s but only with the high power board.
The low power 0 to 12 watt board continued to work normally. Tried a transmit
gain calibration with no effect.
I sent it back to Elecraft and they replaced both the low and high power boards
with revisions they deemed "
That's what I would try next.

Hi,
Is it possible that menu "Tune PWR" is set to 0?

I’m pressing TUNE. Mode VOX etc shouldn’t matte
In TX TEST mode the “TX” symbol on the right end of the display will flash
about once per second. No need to try turning it On to see if it’s on or not.

Are you in CW mode? If so, is VOX enabled?

Not in test mode :(
I get the red TX led bit the display show 0w and - - where the VSWR
display would be when I press TUNE in TX NORM.

Press and hold the right side of the band-switch over "Test" and make
sure you are not in test mode.
You should see the words:
"TX TEST"
or
"TX NORMAL"
It should say "TX NORMAL".

Hi,
My K3 died today, somehow. The radio works fine on receive and appears
to transmit just there is no power indication on my external meter or on
the front panel when pressing TUNE. There is ALC indication but no power
out indication.The only thing I did different was to switch off the
