With DataA you need to adjust the LineIn gain so that you have 4 bars
of ALC action.

Have you tried adjusting TXG VCE? With latest firmware, a setting of
-2dB puts my PSK31 power right where it belongs for a given requested
power out. There's then no need to ride the audio input level, which
is a bad idea given the way the K3 ALC works.

I just applied the latest beta firmware as I have done many times
before, and it looks like this time my power calibration went out
the
window. I'm putting out about 70w on PSK31 when I dialed in 45.
Just wanted to give folks a heads-up to watch their power output
when
they start operating under new firmware, it might be time to re-
calibrate!
It's more than just the power calibration. Even after calibrating
power and
setting the requested power below 50W, with either 2.73/1.98 or
2.72/1.98
the power output on PSK31 (in DATA A) mode often exceeds the
requested
power, which results in splatter. I have been having to constantly
ride the
LINE IN and/or sound card output level controls in this weekend's PSK
contest to keep the power below 50W and PSK signal quality
acceptable; I
have now switched back to 2.67/1.96 for the remainder of the contest.
