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. 73, Don W3FPR ab2tc wrote: > I will do the gain calibration again when I get home. I have done this > several ti

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. 73, Don W3F

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
