AN/ART-13

The resulting communications system was known as the AN/ARC-8 and was the liaison radio set on many larger USAAF aircraft beginning late in World War II.

It is thought that they obtained AN/ART-13 units from battle damaged B-29 bombers that landed in Russia during World War II.

Enola Gay, the B-29 Superfortress bomber that dropped "Little Boy", the first atomic bomb on Hiroshima, Japan was equipped with the AN/ARC-8 combination.

[3] The AN/ART-13 operated in CW (code), MCW and AM (voice) modes and covered LF, MF and HF frequencies up to 18.1 MHz.

Post-war modifications by COMCO and other companies added crystal frequency control capability and were approved for use on civil airliners.
