It has been my experience that when ALC action is allowed for PSK31,
the IMD reading will get significantly worse. Another danger that was
discussed on FT-817 group was that there are sometimes fixed gain
audio amplifiers in front of
First, it ignores all the empirical evidence to the contrary. This
alone would make the statement suspect.
Second, it ignores the different methods and implementations of ALC in
different transmitters.
One of the first effects of ALC is the imposition of an amplitude
modulation on the RF envelop
