I have been using the close call feature quite often lately and I have been getting "hits" on what I believe are control channels. My question is: When the scanner stops and starts receiving the "weird" noise (what I believe to be a control channel) I don't know how to store it into my scanner. The scanner is obviously a trunk tracker. I don't know how to use this feature and I have read the manual. I would think that it would automatically pick up and tg's on that system. I know this is a really rookie question but, I would like to be able to listen to trunked systems on the "fly". For instance, if I head to another county that I don't have pre programmed, how can I program it as if it was a conventional system.
