[Elecraft] K3: CW in SSB mode broken?

Tue Jan 31 16:03:39 EST 2012

Gary and others,

Yes, I momentarily saw it working okay on 6 meters when I did a brief 
transmission on that band.

Unfortunately, as I don't have an antenna for 6 meters, the K3 
encountered a high SWR there. And now it outputs only about 5 watts 
on each band (also in CW mode) when I've dialed an output power less 
than 12W. If I select a power level over 12W, so the KPA100 should 
kick in, I get no output whatsoever.

So maybe I broke something now. :-(

Or the cryptic bug has manifested itself in the CW mode too.

Any ideas whether I could do a software reset of the radio?

Fingers crossed here now...
