[R-390] Wally Chambers (K5OP) Audio Derived AGC

[Dallas Lankford]

No.  My BFO vernier fine tuning mod is done with a voltage regulator,
voltage variable diodes, and a 50K ohm pot (the pot added to the front panel
in place of the DIAL LOCK mechanism).  It was mentioned recently on the
"qth" R390 reflector, and is described in detail in a file that can be
downloaded from the FILES section of the YAHOO r390 reflector.

Best regards,

Dallas
