[Elecraft] Fw: k2

[Scott McBain]

I have a K2 with SSB, 100W PA deck, and 100W antenna tuner.  I sent this in a while ago, and ya'll got it working great.   During the Rookie Roundup, it developed a major problem.  I was on SSB and splattering all over the place.  I disable the pa deck, and set the power to 1W and I'm transmitting between 20 and 30 watts, depending on the band.  All bands are 20 except for 40m which is 30 watts.  I've made a few measuments of resistance and voltage, but so far everything seems fine.  It receives fine, and works correctly in every other way.  I also tried it in tune mode, and with a CW key, and I get the same results.  I did purchase some coax a while back, that gave me fits for quite some time, I finally figured out, the center pin was shorted out to the shield.  I replaced the ends, and everything was working great.  I haven't used it much between then and now, so it may be a contributing factor. Will you recommend what I can do to narrow
 down the problem?
