[Elecraft] [K2] Erratic output on 160m

[Don Wilhelm]

Robin,

It is possible for the K2 to have lower transmit RF gain on 160 meters, 
but then since you can obtain full output by whistling into the 
microphone the K2 RF cahin has adequate gain on 160 meters.  The highest 
gain through the K2 transmit stages is normally at 40 or 30 meters 
although some show the highest gain somewhere between 80 meters and 40 
meters.  In any case, if you get any bars at all on the ALC indication 
that is sufficient for full output.  You might want to try increasing 
the compression a little - I normally run the compression on my K2 at 
3:1 - that will bring up ;;the average power for you.

73,
