RECEIVER RCA BC-348
ACCESSORIES
Morse Key
My morse key type J44 is a J37 fixed to a bakelite base with a switch Teleg./Voice.
The J37 key was the real "workhorse" during the war, it was used as the main part in different variants
designated J43, J44, J45, J47 and J48. A very good overview of these models is given in link 1 below.
The key was of course wired to the transmitter BC349 or BC375, but it was sitting on the table in front of the
radio operator with the receiver. I bought the key to resemble the operator environment.
The J44 key is 13 cm x 7 cm. The J37 is very nice to operate and still popular with radio amateurs.
Spare valves
The valves used in the BC-348-R are:3 each 6K7 (first and second RF and first IF)
1 each 6C5 (oscillator)
1 each 6J7 (mixer)
1 each 6F7 (second IF and beat oscillator)
1 each 6B8 (third IF, detector, AVC)
1 each 6K6GT (AF stage)
1 each 991 (voltage regulator)
Most of the valves are metal types with octal base and top connector.
I have bought a set of spare valves, one of each type, from Radio Daze, link 2. The valves are NOS (new old stock), not used but of old manufacture and in original boxes.
