Had to do a double take for a minute, as in my days in the Army, we could max out our AN/TRC-170 on troposcatter mode at 2.0 kW, with a substantial range on a good atmosphere day.

The use case here, however, is incredibly different. We'd typically be towing 2x 10 kW diesel generators with us, so this is certainly an interesting POC to follow.

one of the fun things about "modern" troposcatter modems is they're pretty much the same as the more advanced SCPC satellite modems you might see in use for a dedicated piece of transponder kHz in the C or Ku bands, and a geostationary-based link between two locations. I've only done a tiny bit of troposcatter but it's my understanding that the extreme loss in the path generally results in using fairly rudimentary modulation (like QPSK 1/2) with a vast amount of FEC in the total percentage.
