Western Electric developed a four-channel crystal-controlled VHF-AM receiver and transmitter for the U.S. Army's SCR-274-N system. The Army did not adopt these VHF components to any extent because of the move to a common British/American VHF capability in the form of the Bendix SCR-522 VHF-AM set. That remained Army policy until the arrival of the AN/ARC-3. The Navy adopted modified versions of the Western Electric units as the R-28/ARC-5 receiver and T-23/ARC-5 transmitter. The T-126/ARC-5 is a late variant of the T-23 which allowed the four channels to be grouped in a 100 to 146 MHz tuning range, smaller than the T-23's.
