I have a new Pro 197 and when I first added the channels I got the trunked talkgroups and now I do not have one of the trunked groups at all. I there a setting to receive them. Mike
Stop (MAN) it on the system you want to listen to and press the middle softkey labeled "TSYS" and the and then the right hand one labeled "Analyz". Using the arrow keys, scroll down thru the system frequencies to be sure you are getting an active control channel. You may or may not actully hear the data channel, but the bottom line of the display will change to a percentage reading and various system/site informational numbers. As long as the decode is above about 60%, you are receiving enough data to decode it. If it is below that or no control channels are getting received at all, you have a problem. You may want to check your outside antenna or feedline (if you are not using one, consider getting one)
If nothing at all, check the database to see if the control channel has changed recently or try the alternate control channel listed. Some systems rotate thru various control channels on a regular basis, just to confuse us I think....
