OK, My opinion: Best practice is to operate at a lever *just below* where the ALC light starts to flicker. This gives you the cleanest signal. It's easier to do if you can use the clipping action of a good RF speech processor, such as the SP-7 or equivalent, to limit your peaks.
Otherwise it's probably OK to adjust so the ALC just flickers occasionally. Too much ALC will increase the IMD of your signal. See: http://www.sm5bsz.com/dynrange/alc.htm On CW, definitely operate below the ALC level. The quality of the tranmsit signal starts to degrade when you go into ALC. 73 -Jim NU0C On Sun, 2 Mar 2014 09:34:20 -0800 (PST), lane denune wrote: > > > OK ; Here's a loaded question for the TR7 Pros out there..."
