The Navy did specify BC-348s at times for installation
in their aircraft.  I have a portion of a manual for
the PBM-5 showing the installation of the BC-348Q
starting at serial number 84690.  Prior to that,
the receiver set used was the RAX-1.

These pages are dated 1948, so maybe this was
postwar. I am wondering if maybe the Navy used up
stocks of surplus BC-348s in the postwar budget
crunches.

The transmitter was listed as the ATC with the RAX-1 and
the AN/ART-13 with the BC-348.

There is also an earlier drawing of the radio op installation
showing a GO-9 with the RAX suite of receivers in a vertical
stack.

The drawing of the radio op position shows a single
AN/ARC-5 receiver in a single unit mount. The drawing is
fuzzy, but it appears like it may have been a locally
controlled unit for the radio operator.

It also shows an AN/ARC-5 installation in the flight
engineers compartment, consisting of a VHF receiver
in its own mount, a dual transmitter mount holding a
VHF transmitter and MF transmitter, a dual receiver
mount holding LF and MF receivers, and the modulator
and antenna relay.

  Plus a pair of receivers and 4 transmitters stowed
in the galley.

It refers to the AN/ARC-5 equipment as "intersquadron"
radios.
