I have the pro 164 radio shack scanner. The talkgroups I am searching for is the the police dept. I know that public service also operates on the same freqs. I am just trying ti figure out who is who. Also not to sure how they are zoned either.
For now, Waco PD is on the Waco/McLennan County
system. Looks like one of their talkgroups is tagged as encrypted, and one as digital, with occasional encryption. But most all of the talkgroup ID's, for now, are analog, so you'd be able to hear them with our Pro-164. I don't own that scanner, but the 'easier to read' manual
online may help, if you need any more information on setting the system up. I know there's several members from the Waco vicinity that post fairly often. By "zoned", if you mean patrol district zones or unit assignments, one of them may be able to shed more light on that.
As I noted initially, there's comments on the McLennan County database page that eventually, Waco may move to the
TxWarn P25 system, which is digital. If and when that happens, you would not be able to monitor them with your Pro-164.
