[Elecraft] K3 single band mic audio anomaly

[Robert Redmon]

As I am (almost exclusively) a cw operator, I had not noticed this until 
recently. On 6 meters (and only 6 meters), when I first turn on the K3, 
if I am in ssb mode, the audio level (output) seems to be very low. 
However, as I continue to speak, it gradually (a few seconds) builds up 
to normal output and behaves normally until I turn the radio off. I 
suspect this is an audio issue, as I have full output on cw from the 
first dit. SSB operation on other bands is normal.  I set the audio 
levels and compression using the operator's manual instructions, but 
only after the output has built up. Are audio (mic) settings are band 
specific? Should I do my setup from a cold start and not after the 
output has normalized? I suspect this is operator error of some kind, 
but just can't seem to sort it out. Anyone have any ideas?
