[Elecraft] K3 unstable ssb power

[Juha Kasari]

Help!

I have K3 #2100. On CW power is very stable, but not on SSB. There is some
change on output power, it is not constant.

If I tune my linear (Titan) on CW with 50 W, output is stable 1500 W. but on
SSB with the same driving power I get only about 1200 W? If I whistle to mic
it takes about 2-3 seconds and power rising to 1500W. Titan has peak power
meter and I have also Bird 43.

I have tested also to 50 ohm dummy load and without linear, with and without
tuner. Really, power is first about 80 W and then it go to 100 W very slowly
on SSB. TXG VCE has no effect.

Why? Is that normal behavior of K3? I have latest firmware, today loaded. I
think it is like ALC react too much and too quickly.
