[R-390] R-392 help

[John Seboldt K0JD]

Hey, the R-392 is the only reason I'm on this list :-) ... I was always 
interested in the R-390 family, but the R-392 showed up cheap. And, as 
others have said, it seems to have less to go wrong with it, probably 
being a vehicular rig.

You definitely want to run it at about 24.5 volts for filament life, 
according to a source I heard from when I first got it - makes sense. I 
had the same experience you did, where a little switch exercise got it 
back to life. I do have one nice quirk - the thing can go dead, but 
tapping the chassis near one of the top deck tubes brings it right back. 
Haven't dug inside to find the problem, since it's so easy to pop the 
thing out and tap... the time may come when I will have to, though.

Nice sound with the wide LC filter bandwidths... someday may try tapping 
the IF into something external, but it has a nice feel to it just the 
way it is. Certainly not a rig for a crowded band!
