PRO-95 & trunking
10point said:
I am new to scanning and have a pro 95. ... I have my trunked frequencies on bank 0 and regular ones on bank 1. My channel 008 gets lots of activity when I just put it there manually and leave it there but when I am scanning banks 0 and 1 I am not getting near as much activity. Any ideas?
That sounds normal to me. However, I'd like to clarify that you only have ONE trunked system programmed into bank 0. That means most of the 100 channels in bank 0 are currently not used.
By your opening statement, channel 008 is one of the trunked frequencies of your local system. I strongly suggest that you read your owner's manual, and the WIKI section here at RR regarding TRUNKING. Once you understand the basics of how trunking works, you will understand what you are seeing.
I see this issue come up a lot. People try to listen (even if just as a test) to a TRUNKED system in MANUAL mode. It does not work that way with these scanners. Scanners such as the PRO-95 are designed to monitor the active control channel and switch to desired voice channels. Therefore, when scanning, the PRO-95 will always display the voice channel on line 2 and the control channel (text or frequency) on line 3 with the "scanner's channel number" of where you've programmed the control channel.
Interestingly enough small trunked systems could function with just 2 frequencies; one for the control channel and one for voice. As long as everyone does not talk at once, all voice COULD be on the same frequency. So with your scanner in MAN mode on that frequency, it will appear to be very busy. In SCAN mode, there are a lot of other factors that have to be set correctly - is the bank open or closed, are talkgroups programmed, are sub groups turned on, are talkgroups locked out, are all frequencies set to the correct mode (which would never be FM), is the mode of the bank set correctly .... ????
Bottom line; while you can listen to conventional channels in MAN mode, you can not really listen to trunked conversations that same way. In order for the PRO-95 to track trunked conversations, it must be in SCAN mode (and all that stuff above set correctly).
I follow what you are saying but shouldn't I put in all 8 frequencies and not just the 3 red ones?
You only "need" the ONE frequency which is the current control channel. The problem is that they switch the active control channel from time to time. I always program in all frequencies for a TRS, but I lock out those which are never control channels because it slows down scanning (by a minute amount).
The one I am getting a lot of activity on is 867.71250 which is not in red.
Is this VOICE activity or DATA (control channel) activity? If it is VOICE activity, IGNORE IT. The scanner only needs the active control channel. Paying attention to where the voice activity is will only confuse the issue.
What are the CC's? Also, I do not have any of the convential frequenices in the same bank as my trunked ones.
You can find the active CC yourself. Go to MAN mode and step through each channel. You'll know the CC when you find it. It won't be voice. The last line of the display will eventually tell you it is a control channel. Then press SCAN to listen to what's going on.
