I thought the best way to drive an amplifier was to increase drive
until output no longer increased proportional to input; eg output
increases 3-dB with an 3-dB increase in drive is linear. Isn't the
point the increase drops 1-dB the upper limit?
That is how I determine best drive level on VHF linear amps. Most
folks run up drive until they reach saturation (no change in output
with increased drive) and then operate SSB there. No wonder their
voice peaks are cut off causing splatter. BTW high speed CW should
not be run at saturated power, either. CW actually has bandwidth
though at 5wpm probably not measurable <ha ha>
ALC was a good concept that never worked very well (negative feedback
gain control). ALC meter on the K3 is useful for setting audio drive
just to the point ALC begins to act (four bars with 5th flickering).
But I guess all of you know that - right?
