[R-390] Check.... your newly acquired R-390A

[ALLEN MARTIN]

As I said in my original post I have good audio out and can change filter widths. The BFO works or at least seems to as I can hear the tonal change. I will try your suggestion. Tuning to 00.000 doesn't do anything. I do have lots of indication on the carrier level meter where ever I tune. but no signals. As the rf gain works well perhaps the first mixer or the 17 MHZ oscillator isn't working. I will check those out and see what I find.

Tnx!
Marty

   G;day  list...
So your  latest R-390A  doesn't   utter a  sound  at turn on ?....I'm
indebted  to  an old  email  from way back 2007 and  a  long time user.
  Check   with this initially..
Dial receiver to 00.000. You  should  peg the  Carrier Meter. Flip the  BFO
 on to see if you hear a tone .
This  checks  everything back  from the  headphones  to the  First  IF
Mixer ( you are receiving the
17MHz  LO) , If you have the meter pegged, then everything  from  V202  on
is  working-  at least to  some  extent.   That leaves V201 stage  and the
antenna relay.
At least it is a place to  start   to  do  additional  troubleshooting.
Cheers
