[R-390] SSB reception with R-390A

[Mike Sullivan]

I have great experience with the "Lankford mod". I used genuine diodes
(1N4148) and increased bfo injection by placing about 50 pf cap in
parallel with C535. AM reception was alterred a bit - in my case the
already strong local am station was distorted ( over 100 perhaps 120 on
carrier level meter). Others (normal levels upt to 100)
ok, but seems am demod audio level was lower. SSB came out good.
