[R-390] Penultimate recapping an R-390A

[KA9EGW]

I've got the 2 diodes and 47pF added in mine, and it now has everything I
want for SSB...

"The problem isn't instability or lack of a product detector, it is the low
BFO injection.  This can be much improved by increasing the BFO injection
capacitor and re-tuning the BFO neutralization.  I wouldn't say it works
"perfectly" compared to, say, a 51S-1, but it does work just fine."

And for another simple tweak which works wonders alongside the ones which
Don mentioned, don't forget the 2 diode (Dallas Lankford) AGC modification.
