Hi Jerry,
I had the same problem last year. I had the early 4 band board. I purchased
the KFL1-4TRIMKIT. I tried to install the trimmers but I had a hard time. So
I just purchased another four band kit. Now the K1 works great from the
Appalachian Trail.
72 and Thanks,

Subject: [Elecraft] K1 Acting up on 20M and 30M
I have K1 SN950 with the 4 band module, Antenna Tuner and battery
module. It has been working like a champ for 3 years. Now, it has
decided it does not want to transmit on 20 meters and weakly on 30M.
Radio works fine on all other bands. Radio receives fine on all bands.
When I attempt to tune on 20M, it fails to get a match, drops power to
0.1 (no matter how high I initially set it) and reports "Plo". If I go
in and check the SWR from the last tune (rx.x) it reports r0.0. On 30M
I do get a tune, I get a reported SWR of r9.9.
If I check the antenna with a SWR Analyzer, it reports that the antenna
is about 1.7 at the frequency I am trying to use on 20M and about 2.1 on
30M.
I put a power meter in line with the radio: It reports near zero output
on 20M, about half power on 30M and appropriate power on all other
bands. If I swap out the antenna and put in a dummy load, the meter
shows R6.3 and about half power on 30M, and Plo again and no measurable
output on 20 M.
I manually cycle through all the relays --- per the troubleshooting
guide --- and they all are clicking --- none appear to be hung or dead.
Any Ideas?
