[Milsurplus] BC-348-C (S)

[Robert Downs]

Fairly early in WW-II the Army Air Corps quit issuing the 5-band BC-348’s that did not cover the LF 

band below 500 KC because most of the aircraft equipped with the BC-348 were going to parts of the 

the world where many of the airports were not equipped with HF equipment.  The Army Air Corps quit 

installing the early model BC-348’s in most of the bomber fleet.  I have never seen this mentioned in 

official documents but there must have been a significant quantity of un-issued BC-348-C’s on hand 

and someone decided to convert them to 6-band units which got the model BC-348-S assigned.  This 

was not repeated so either it didn’t save much money or there weren’t enough unissued A, B or D models 

to make it worth doing.

After several posts on the BC-348 and modifications, I have a question.  I have a 

BC-348-C made by RCA and has another tag, "modified by Belmont, BC-348-S".

>From what I can determine the modification was done to add the LF band.  Was 

anything else done?  Haven't been able to determine what all it entailed.

It has been further modified to include an AC power supply and an added

meter, "S"?  Came from engineering lab at state university.

Just curious. Any help?

I also have a BC-348-P by Stromberg-Carlson.  It is complete with H/B

built in power supply.   Both will be put on my auction soon.
