1) Your programming of the radio?
2) Is it a P25 or 3600CC system?
3) How the system is configured
4) What ID you use in the radio
5) What level of auditing the admin does
6) If the person who watches the system sees it and whacks your radio
So the question is....
Is it worth blowing up a $2000+ radio to listen to a system where a $500 scanner will work?
Also, you'll run into problems if you clone an ID and it's a true smartzone system........
Edison is a trunked system, and the only thing you'll be able to listen to on that system digitally is Fire/EMS . Everything else is Analog. In fact, they even offer analog frequencies for Fire / EMS. Police are completely encrypted.
I've seen this done with a non-Edison XTS. It can be done, I just don't know any particulars. If I had the money to blow on XTS's and the like, I'd be in-the-know.
I much prefer late-model Icom radios. Cheaper, sexier, smaller, smarter. But then again, if I had the cash, I'd get back into Moto gear again.
