Juha,
Tuning within any band will not reset the power output controls, however
changing bands does reset it.
As Joe has mentioned, do
I press the TUNE button and this solves the problem.
Will it be solved with a firmware update?

Well, what I do is when I change frequencies, I go to cw and key it until the
power comes way up. Yes, it is a pain. Some may say you can't see a
difference on the s-meter but if you use an amp with tubes, that "little
extra" that takes time to come up makes a difference. This could be tweaked.

Knut,
That is not possible. If it were done, there would be a large variation
in output power from band to band - the gain of the transmit chain is
not constant from band to band.

I will do the gain calibration again when I get home. I have done this
several times in the past without improvement, but not terribly recently.
Maybe there is a relatively recent firmware improvement in this area? Would
it be possible to change the firmware to not reset the ALC when doing a band
Juha,
Tuning within any band will not reset the power output controls, however
changing bands does reset it.
As Joe has mentioned, do the power calibration, it will help. The power
control mechanism does use the data obtained from the TX gain
calibration, so yes they are related.

Not so good behavior on the contest, where is alltime tuning.

An undershoot of ~ 20% for the first few seconds of transmission on a
new frequency might be an irritant but an overshoot or aggressive fast
acting ALC leads to spatter on peaks, this is very common issue on the
bands today
An undershoot of ~20% on peaks (it's less on my K3) is negligible in
term
Hi,
No, please, this is not a power calibration issue! A huge number of K3 users
have complained about this propensity of the SSB power to aim
"conservatively" for 50-80% of the requested peak power and then slowly,
very slowly climbing up to the requested power. Once reaching 100% it stays
there

Hello,
When I whistle to mic and tune my linear amplifier, I notice that last watts
going up very slowly. Without linear I tested and sometimes first 80 watts
out normally but from 80 to 100 watts it takes about 2-3 seconds.
When I am using my linear (Titan, has peak power meter by led) last one
