This does seem to be the MO. Austin went to repeater on 155.46 then switched to P25 shortly thereafter. I heard the dispatcher announce that the radio shop was taking the old base down. Shortly after that they were up on 155.4675 (A2) in digital w/repeater on. I suspect they will drop the repeater mode after some time.mam1081 said:I'll bet they are working on Mineral Wells next - the dispatcher and mobiles were both heard on 155.46 on Friday 4/11/08 (repeater mode - seems to be common when they are about to switch).
Historically speaking, when you are in half-duplex mode, you, the dispatcher, are only having to listen to 154.680 or 154.695 from your local tower, therefore only hearing closeby units that can be heard from the tower you operate. However, since most of the state was only using two base station frequencies, 155.445 and 155.460, if you were to turn the repeater on, the dispatcher would be forced to listen to the output, and would most likely experience much intrusion from neighboring stations. For instance, Tyler has been getting blown out of the water by Bryan's Repeater on A1 as of late. IMHO, the thing for DPS to do would be to do away with the channel plan and license other frequency pairs to reduce interference. The radios they have can hold 256 channels..............TXEMT said:just curious as to why they would turn the repeater off, when San Antonio switched they had the repeater on and it sounded good most areas...just seems like it would be better for the troopers to hear each other...never have understood why they like the duplex stuff. Guess major cities would need more that one tower to cover the entire area.
To elaborate on Tom's reply, the Unidens don't decode NAC so just program them as Tom stated, Freq only, FM mode, no tone, an no tone search. (I do not have a 396, but tone search on the Pro96 ignores digital channels and will not break squelch).W5TWX said:How do I program the 396T to receive the new DPS digital system? I'm confused...
What is 118NAC?
