Mike, I would guess US military but it could be just about anyone with the cash to afford the equipment.Any ideas about the nature or source of these, even if just based on the frequencies used?
nick, my guess would be most likely military, but not US military. As far as I know the most common frequency hopping capable radio systems that the US mil uses are HAVE QUICK and SINGARS. And these are VHF and UHF, but not HF.Mike, I would guess US military but it could be just about anyone with the cash to afford the equipment.
I see a lot of things happening in that range, including a repeating non-linear sweeper, but no hopper seen on the West coast.The 10 meter hopping is back and it's around 28.305-450 this time.
