Programming Trunked System into BCD396T

[AWiley]

Hi, I am trying to program the Charlottesville/Albemarle, VA 800 Mhz system in into a friend of mine's scanner. I have only programmed the control channel frequency and all of the talkgroups ID's into the scanner. However, even with these things programmed I am having garbled audio problems. I have two questions:
1. Do I have to program ALL of the frequencies listed for this system, INCLUDING the control channel? What will happen if I leave the control channel as the only frequency for this 800 Mhz system in the scanner?
2. I am wondering if it is because I have only programmed the control channel that the audio frequently sounds garbled. This system, to my knowledge is not encrypted with the exception of the P25.

FYI, I DO have the latest firmware version installed on the radio. Also, my friend lives within 5-10 miles of any given tower.
I also have a BC 796D that has the same 800 Mhz system programmed into it with ALL of the frequencies including the control channel channel into it and the talkgroups. I am not having any audio problems with my BC 796D and I also live within 5-10 miles of any given tower.

Any help? Comments? Suggestions?

Andrew,

You can just program the system with the control channel. You don't need the other frequencies, and they definitely won't help the audio problem. To adjust the digital audio, see page 102 of the manual. Also see this page on the RadioReference Wiki:

Hope this helps.

Okay. Thank you very much for that information.

I have a question about my BC 796D. For that scanner with the same 800 Mhz system, I have all of the frequencies programmed into it including the control channel. It is working fine. However, when I program just the control channel in. It is recieving the system, but no talkgroups are becoming active. What could be wrong?

You probably need to set the 796 for control-channel only mode. It needs to be "told" to go into this mode. It's in the menu settings.

It's a Type II system, so don't program it as a P25 system.
