The hell it doesn't. If the O/P intends to program a subscriber to actually properly function and RX at all sites like a true subscriber, than it sure does require a valid RID, channel pool set correctly as the system author created, etc.
Yep, that's why we RAS. To keep bootleg, unauthorized radios off our systems. Mine is setup that way. Doesn't affect a scanner though (unless encryption is utilized), so a scanner will work just fine..hint hint...
Best. Advice. Ever.
and some folks may not want to assist others in potential commission of a crime, and some folks on here have vested interest in the very networks/systems others publicly profess a desire to penetrate, which is why the general GOOD advice is to buy a scanner if one just wishes to listen. Did I mention the SDS200 does a fantastic job of scanning DMR conventional and trunked systems?
