Yes Carzee,
The Land Rover Series 3s and Mogs had been transported to Nashua, NH prior to the advance parting arriving.
As stated above, the subsystem encompassed base stations (on Unimogs) and several transportables (on Land Rovers).
It was designed for a high density VHF environment which I believe was it’s major flaw for the army. Our doctrine at the time was the defence of Australia where in our wide open spaces, and distances, Comms would have been via HF notwithstanding our transition to encrypted satellite and burst technology.
The system in the base stations worked by constantly scanning the electromagnetic spectrum.
As soon as an enemy pressed the pressal switch on his radio handset, the system would identify the frequency being used and calculate a Line of Bearing (LOB) in the direction of where the signal was emanating from.
An operator in the base station then had the ability to then listen to the enemy signal/chatter to identify interest in the call sign. If there was an interest, he could then engage multiple transportables to also lock onto the frequency and calculate their individual Line of Bearings. Via triangulation with multiple LOBs, a location and grid reference with an identified Circular Error of Probability (CEP) was calculated. This could then be used for various purposes.
Given how it worked, the system had it’s own identifiable electronic signature. This was problematic as the preparation time to set up and pull down the masts and antenna arrays was considerable.
The Unimogs had a large hydraulic antenna mast but the transportables had manual masts. While in NH, we noted that Sandars had US vehicles slightly larger that the Land Rovers with hydraulic masts on them for the South Koreans. We joked that we needed those, and the South Koreans needed what we had.
Anyway, is was long ago and the above is my recollection of it.
