The 618W designed by Collins Canada has a form to fit in the avionics bay of the F104 Starfighter. Supply is 400Hz ac. There are 3500 channels, spaced 50kHz. An intercom module (the brown box) is included. The air-air heat exchanger moved to the other end.

The ARC52, shown here, had 1750 channels, spaced 100kHz from 225 to 399.9 MHz, with AM modulation, and 20W RF output. The chassis includes a separate receiver on the guard frequency (243MHz,). The 400Hz ac supplied version is the RT332/ARC52 and the 27Vdc only version is the RT424/ARC52X. The ARC52 was updated during its lifetime. The first version had 4J6 triodes in the UHF stages, the last version had seven 7077 planar triodes. |

The PTR175 was made by Plessey in the UK. Although size, number of modules, and power consumption are exactly the same, the PTR175 includes 350 VHF channels from 117-5 to 135-95 MHz . The design could be configured for retransmit/relay operation, fsk data demodulation, and ADF antenna support. |
