[Elecraft] KX3 low power on 15Mtrs

[Don Wilhelm]

Bob,

Are you driving the audio level sufficiently?  Inadequate audio drive is 
a common cause of such 'power hunting'.
You can do this off the air - turn the power to zero or connect a dummy 
load.
Then turn compression to zero.
Talk normally into the microphone and adjust the MIC GAIN to produce 5 
to 7 bars on the ALC meter.
Now you can increase the compression to the desired level.  3 to 6 dB is 
often suggested, but it is your choice.

After a band change, the initial power should be low, but should quickly 
increase to the requested level after a few syllables.

73,
