No pain, no gain.
Thats also why you have 2 hands (-;
Ive zener regulated the BFO and last IF in my SX-17 as well as the HFO and
added a TC cap to that stage. Stability is more than tolerable.
The next step is to figure out a no holes mod to the NC-300 and HRO-60.

Modify the BFO for variable injection level and connect to the last IF
thereby maintaining AGC. Its almost as good as a sync detector for
selective fading and its easier to follow a slightly drifting carrier.
Easier said than done. Sometimes, the change in injection level changes
the loading on the bfo and changes the pitch. This is what happened with
my RME 4350. A cathode follower can solve the problem, though.
