Is there a way to download only the control channels for the ohio marcs system using sentinel? it is downloading all of the site frequencies right now. Thanks
Actually it does hamper scanning. If the system has data (IV&D in Motorola speak) Uniden's can interpret the data channel as a control channel and park on it. Which means you hear no calls. No need to argue this as I've 100% confirmed it happens (at least on a Motorola P25 trunked system).You don't need to exclude voice channels as it doesn't hamper the scanning procedure. When it detects the control channel it stores it to the site and at the next scan cycle it goes directly to the last used control channel and ignores any other channels programmed. Only if it looses the CC will it hunt for it among all channels programmed for that site.

100% THIS! The issue has been raised with Uniden/Joe for at least 3 years now, and still no fix for it.Actually it does hamper scanning.

This will only happen when you first turn your scanner on, but it does happen.
Yes, you'll need to do several things to help scanning simulcast systems with a non-simulcast scanner. Set a longer hold time for the system. The defaults can be increased to 5 sec and the delay for TG's can also be set longer to 5 sec and both changes will help it stay on the site and a conversation even if it intermittently looses decode due to too many bit errors from the simulcast issue.When dealing with simulcast systems in scanners not designed for them, I find that the scanners acquire the control channel again much faster after losing it if it doesn't need to search through all of the voice frequencies especially in sites with a large number of frequencies.
You have to spot that real easy, that the scanner doesn't scan anymore and are parked on a data channel and you hear no conversations. It isn't per se scanning, it is monitoring the system. It probably isn't considered being an issue as it is so easily detectable, just push avoid on it. It can only happen when you initially start scan and that V/D channel happens to have data and the control channel happens to be the one below that in the frequency list for the site.Actually it does hamper scanning.

What good will pushing avoid do? The radio thinks it's on a control channel, so pushing avoid results in an error beep.You have to spot that real easy, that the scanner doesn't scan anymore and are parked on a data channel and you hear no conversations.

It's a real problem and Uniden needs to address in my opinion.
It's almost no point in turning off the screen as the power saved are very small and not worth it in relation to the nuisence it creates.I have no idea it's stuck because the screen shuts off and the scanner is making zero noise.
I agree. I can't tell you how many times it suddenly occurs to me the scanner has been really quiet, only to find it's stuck on some channel and I have no idea it's stuck because the screen shuts off and the scanner is making zero noise.
This sounds like the Display times out more than shutting it off.It's almost no point in turning off the screen as the power saved are very small and not worth it in relation to the nuisence it creates.
