[Elecraft] K3: SSB vs. CW/DATA A with TVTR

[Don Wilhelm]

Udo,

If you are measuring average power rather than peak power, you will see 
a marked reduction in average power with SSB even though the peaks are 
the same power as CW and DATA.

Set your microphone level in the order indicated in the manual (you can 
use TX TEST).  Set Compression to zero, then adjust the mic gain until 
you see 5 to 7 bars on the ALC meter.
After that, increase the compression as desired.

73,
