But it probably isn't a lot of equipment.

Back a few years ago, ARRL's QEX newsletter printed some stuff about
government proposals for new radios that were the High Frequency
equivalent of a trunking radio system. These were frequency agile

establish a connection on each end, no matter what the conditions.

Sounds like somebody was messing around with a prototype.
