[Milsurplus] Radio Identification

[patrick jankowiak]

These were mounted in the backs of vehicles, such where you might find
a GRC-106. The UHF part was used to communicate with aircraft. There
should also be a long box with an insulator on it, about 11x11 and
almost 3' long, which is an automatic tuner for the HF rig. 2-30 MHz
am, usb, lsb, etc.. 

The 618-T1, -T2, and -T3 have diferent power source arrangements.

Case #1
Collins 618T HF transceiver
power supply
associated relaying and connections, racks etc
control box (mounted on outside of case)

Case #2
Collins ARC 51 UHF transceiver
Collins VHF transceiver (aircraft freqs)
power supply for radios
associated relaying, connectors, racks etc.
control boxes for both units mounted on outside of
case.

Any ideas what this particular system was used for?
Possible tactical system???  Looks like the HF unit
could be used for Ham use as all interconnections are
intact.

Thanks for any help.
