[Milsurplus] RE: Russian transmitter P-805

[Meir WF2U]

Ben,

It's an R-805 (or RSB-5 by the old nomenclature). The Cyrillic letter which
looks like a P is R and the C looking letter is S in English. BTW the R-8xx
series denotes airborne radios. The RSB-5 was not used with the US-9
receiver which is the BC-348 copy, but with the US-P  receiver which doesn't
even resemble the BC-348 It is a pre-WW2 Soviet design, but it's a pretty
decent receiver. It's physically smaller than the BC-348.
The R-805/RSB-5 is actually comprised of two transmitters, which cover
different frequency ranges, but together they span 2-12 MHz.
Early in its production, the RSB-5/US-P was also used as a vehicular radio
set. After the war, when the new nomenclature came about, obviously it was
categorized as airborne equipment, as it was mainly used on aircraft.
The US-9 receiver (BC-348 copy) was used with the R-807 (RSB-70 by the old
number) which is the ART-13 copy.

I'll look into my Russian radios folder on the bottom of my paper pile and
may find the RSB-5 schematic... I know I have the US-P and the US-9
schematics.

Subject: [The WS No.19 Group] Russian transmitter P-805

Long shot I know but worth a try. 
 
I am looking for curcuit diagram of the Russian transmitter P-805 (or
PCB-5)
 
This a WW2 tx, used with the Russian copy of the BC348,  and it has a
rather 
big pa tube, GK-71, that should run quite a bit of power. 
 
Anyway, if anyone can help, or point to such help, I'd be most obliged. 
 
cheers, Ben G4BXD.
