The BC-348 also was used in the B-47A, the YB-49, and presumably also the XB-35, although I have not seen a reference citing that installation. The R4Q-1, the USN version of the C-119, also used the AN/ARC-8 but added an LM-14 Frequency Meter to the array of equipment. By the way, it was the X-1A that definitely used the VHF ARC-5. Wayne
