I already have tons of scanners. As stated these don't work well with simulcast and the sds 100 is so expensive it will be awhile before i can afford that brick to use.
OK, I get it. Good scanners can be expensive.
You know what else is expensive?
Getting your radio popped by the system admin when it accidentally affiliates with their system. Once your radio gets bricked, there's no good way to undo that. If you keep it up, they come looking for you.
Rather than buying random radios off e-Bay, might I suggest that you save your money and get the right tool for the job with a proper antenna?
If you really MUST do the professional radio thing, for whatever reason you have in your head, at least get one that can be set up to monitor a trunked system with ZERO chance of it affiliating. I'd recommend looking at the Harris radios. Do. Not. Buy. One. Do not buy one. Do not buy one. Spend the next few months studying how its done, exactly which radio with which feature set you need. Find the software and the correct cable and try it. Or get somone else to do it for you.
But, long run? Cheaper to get the right scanner, plus you have a lot more capability than a single band radio.
