    We could use the terrestrial repeaters here in Boise. Everytime I go downtown, goodbye signal...

    I can clearly tell the difference that XM system sounds clearer. Though these days both sound worse than HD Radio. I have a 2016 Mazda CX5 Grand Touring. The SXM radio in it doesn't go any higher than the channel 200's (sports stuff). I'm missing out on channels in the 300's like Faction the covers channel, velvet, rockbar, utopia, rock and roll hall of fame radio, etc..

    If I were to get it again I would just use the streaming service and bluetooth it to the car. More channels, on demand, better audio quality.

    For all the years these services have been out, I am quite surprised that nobody has cracked this yet. I remember the cracking/hacking game was huge in the days of Videocipher I/II, cable descrambling, cubes, filters, universal descramblers, 3 musketeers hack, stb cloning, card cloning, card emulation, etc.. No one ever seemed to figure out Sat radio.

    I doubt there’s much demand. Why hack it if you can’t sell the hack?

    We have a subscription for about another month. Even still, that stupid radio defaults back to the “Subscribe to SXM” channel. Kinda stupid, and annoying.

    Modern demodulation and decryption is done mostly inside VLSI chips so breaking into it is next to impossible and emulating it in a combination of hardware and software is difficult. Gone are the days of pithing circuit boards with logic probes to see what is going on.

    Mine does that when I pull into the garage. If I lose the signal before I shut the truck off, it will revert to the demo channel when I back out the next time and it receives the signal again. It usually takes me a few minutes to realize it. Just as I'm getting out of the neighborhood, I'll wonder why the heck I'm hearing commercials. :eek
