Red November: Inside the Secret U.S.-Soviet Submarine War Paperback

THE AUTO TUNE WAS NEEDED TO FACILITATE RAPID QSY. THE 24 VOLT AUTOTUNE MOTOR
SUPPLY WAS COMMON FOR RACKS FULL OF THE RECEIVERS. OPERATORS WERE INSTRUCTED
TO SWITCH FREQS ON EACH RECEIVER INDIVIDUALLY, ONE BY ONE. HOWEVER, SAILORS
BEING SAILORS, PARTICULARLY AT SHIFT CHANGE, THEY WOULD GO DOWN THE RACK OF
RECEIVERS, FLIPPING ALL THE SWITCHES, ONE AFTER THE OTHER WITH OUT WAITING
FOR THE PREVIOUS RECEIVER TO FINISH AUTOTUNE..  THE LOAD ON  THE  24 VDC
SUPPLY WAS ENOUGH TO KILL IT IN A CLOUD OF SMOKE.  THEN TO  QSY,  THE OPS
HAD TO UNLOCK THE AUTOTUNE AND MANUALY SET  EACH R4ECEIVERS THE OLD FASHONED
WAY.

I am new here with my first post. In the 60's I was a morse code inteceptor
in the Army Security Agency stationed in Asmara Ethiopia and Vint Hill
Farms. I used a R390 exclusively. About twenty years ago I bought a R390
from a HAM in Maryland and it sat covered up for years. Well, now I am
retiring at the end of the year and decided to get back to getting my
license and getting my radio restored. I got it cleaned up and now find that
it is a R391. The auto tune version of the R390/A. I took it to Howard Mills
for restoration and was emailed  a day ago stating that it is finished
waiting for pickup. Does anyone know who used the R391? Was it the Naval
Security Group, Army Security Agency, etc? I find that there were only about
1450 produced but there is very limited info on the web. Anyone use one?

Thanks,

Rich
