Hi Juha, Are you use 2.7KHz filter? If so please check the shift freqency setting. One of my friend meet this problem on SSB mode, I checked his setting, found he did not correctly set the filter shift freqency. After set to correct value, no problem now. 73 de ba4rf,David 2010/3/29 Juha Ka

DPDT vacuum relay on the rf deck. The coax comes from the RF deck directly from the relay, then directly to the radio. Any suggestions for a fix, besides running qrp? John --- On Sun, 3/28/10, Ruben Navarro Huedo wrote: > From: Ruben Navarro Huedo > Subject: Re: [Elecraft] K3 unstabl

Same here. I have to overload a little ALC and CMP and it solves almost all the problem, but it continues. Before the k3 i owned an Icom 7700 and with the correct ALC and CMP it had a very stable SSB Power. I am sure it can be solved with a firmware update. El 28/03/2010 20:30, Jan Erik Holm es

Doesn´t seem to be a fix. My K3 is just about the same. Jim SM2EKM -- Juha Kasari wrote: > Thanks, > > Ok, so it is feature! > > Yes I have adjust MIC and CMP just like manual, not effect. So there is no > solution to problem. > > juha > > > 2010/3/28 Dave, G4AON > >> Juha this

Juha this "problem" is an old one. Some time back the K3 had poor ALC which allowed for overshoot on peaks, the firmware was altered to soften the ALC control with the results you (and the rest of us) experience. The power can slowly increase over the first few seconds on SSB, the effect is les

Help! I have K3 #2100. On CW power is very stable, but not on SSB. There is some change on output power, it is not constant. If I tune my linear (Titan) on CW with 50 W, output is stable 1500 W. but on SSB with the same driving power I get only about 1200 W? If I whistle to mic it takes about 2-3
