[Elecraft] Setting audio levels (power out) in Data A for RF output stability on K3s

When I use the Data A or AFSK A modes, I set my line in to just fill the
lower 4-5 bars of the ALC scale, and then adjust the pwr out for the
desired level. what occurs when I xmit is an increase in RF output as it
rapidly drifts up. If I adjust the pwr down it still drifts up. This is an
issue when I want to either run very low output power or closely control
the output of my KPA 500. I did not have this issue using the signalink
with my K3, but I do with the K3s and the USB audio interface.

The output power reacts as if there is ALC or AGC increasing the output
level automatically. Any ideas?
