The RT-136/GRC-13, made by RCA. Almost the same tube line-up as the GRC-9,
but the shape and size is about the same as the TBX.
Uses accessories similar to the BC-1306 and GRC-9 but different plugs.
The transceiver is a 10 crystal controlled channels arrangement, with a
single channel selector knob for both the rx and tx.
BA-48 fits inside the radio, access via front panel door.
I have one of these things, unfortunately without accessories/cables. RX
works fine with BA-48...
I think it was short lived with the Navy/Marine Corps and probably the GRC-9
was its successor.
