[Milsurplus] What is the difference between a RBM and RBSreceiver?

[howard holden]

There may have been other uses but the RBM was the companion receiver to the TBW transmitter.

How did the Navy use RBMs during the war?

The RBM-5 from S/N 1011 also has the dial lock.  That plus R-506 are a couple of the reasons that I thought that the RBM-5 HF was probably the same receiver as the three RBS models.  And the more common (at the time they were actually in service) power supply for the RBM was probably the dynamotor unit.

I think the major difference between the RBS and the HF RBM is the mounting
system and the dial lock on the RBS.  The power supplies are quite different
though.  The RBM power unit is a conventional rectifier; the RBS is the
rectifier plus an audio amplifier using a pair of 6V6 tubes.
