I'm not sure of the chronology, but the AN/ARC-21 has an auxiliary receiver
with mechanical filters that covered the same frequencies and modes as the
RT-128A/ARC-21. That was the R-224/ARR-36, a remote controlled (with a
C-451/ARC-21 control box) unit that is about twice as large and heavy as a
BC-348. I believe the R-224 tag indicates that it likely pre-dates the
R-439/440/441 SRR-11/12/13 units. Still, it looks like an early 1950s RCA
sweep.
If anyone has a DY-100/ARR-36 dynamotor they don't need, my R-224 could use
it.
