Wrong, Len. With the AGC disabled and BFO on, the *AF* gain
should be
at maximum and the RF gain used for volume control.
For both SSB and CW/Morse reception
...and for RTTY.
Well, that depends on the type of RTTY operation and equipment. While
we hams usually use "SSB" detection of RTTY signals, and then an audio
TU, there are other ways.
There was a QST article in the late 1950s or so, showing an adapter
that used 'real' FM demodulation of the IF signal. Built around a
BC-453 Command set. Had a 'scope built-in, IIRC. Complete receiving
setup in a rack mountable unit, just feed the IF signal (190-550 kHz)
from almost any superhet to it.
I'm sure there were manufactured equivalents.
I'd have thought the old boy would have known all that
with his decades of experience.
"It's a trap"...
With the BFO injection of most old
boatanchor receivers,
(like the R-70?)
he'd likely hear little or no beat note
at all using the method he advocates.
Maybe that's the point...
