Regarding verifying the primary and alternate control channel frequencies, program those frequencies into the BCT8 scanner as conventional channels. Just like you would a VHF frequency. Then scan them. One of them should have the familiar idling diesel engine noise on it - that's your active (at the moment) control channel and it would verify that your scanner is capable of receiving the site in question (Jasper). If you don't hear the control channel audio on one of those frequencies, then one of several things could be happening:
- your antenna isn't capable of pulling in the control channel signal (ie, a reception related issue)
- the active control channel is on a frequency that isn't listed in the database
- there is a fault/problem with your scanner
If you do hear the control channel noise, the you want to verify that the control channel frequencies you programmed as "trunked" frequencies are correct. Assuming they are, now you know there is a problem with your programming or operation of the scanner - operator error.
I'm sorry I'm not more familiar with that model radio to help you further. You might try posting in the Uniden formum and someone who is familiar with that model might be able to help you.
One general point I'll make, and this isn't directed at PIFD or anyone in particular: the RR database, which supplies the data that these "automated" scanners use to work properly, depends on local listenters' submissions to stay accurate. Things change on radio systems fairly frequently, and if there are no listeners in an area capable of figuring out when these changes occur, the database becomes outdated and inaccurate, and these automated scanners cease to function properly. That's a notable flaw in this arrangement we have between RR, scanner manufacturers and consumers/listeners. I understand that most scanner listeners don't care one bit about the details of how these systems operate - they just want to listen. I don't have a problem with that. It's up to those of us who are interested in how these systems operate to maintain the ability to identify changes and submit them to the database. The number of listeners that fall into this category seems to be dwindling.
I hope you get your problem figured out. Good luck.
