Great find! THX and HLX callsigns. Imagine that. Mine's much more cumbersome. Hoping for something a little sleeker for the full licence.
Encryption would pretty much scupper this kind of listening nowadays. We're not allowed to use it, as licensed amateurs, but I'd put most amounts of money on the military using it. You could at least pinpoint the origins of signals, which could be useful.
- Steltek 10y agoForget encryption, below the noise floor data modes like JT65 must be ridiculously hard to detect. Of course, what really renders this all moot is the Internet. That giant blind drop in the sky (cloud?).
- superuser2 10y agoIt's not hard to imagine ISPs being ordered to shut down in a total war scenario. Or at least block encrypted traffic. There is no plug to pull to shut down radio communications, and active jamming of frequency-hopping systems is hard.
- luxpir 10y agoIn 'theatres of war', combat situations etc., would net connectivity be much of an option? Doesn't satellite have to be stationary? And data modes must be fantastic for the military, agreed. I don't know if any encrypted streams have been detected by amateurs, do you?
