Welcome to RadioReference.com!!!
I have a PSR 300 and Ihave programed 68 Trunked Talk Groups on it for Maricopa County in Arizona.
I think you are trying to program
this system.
I am fairly new and would like to know how to open and scan them. The manual makes no sense to me in that category. I put them in bank 000 along with 8 trunking Frequencies which I have no problem scanning.
This one is a little more difficult than usual for me because there are MANY sites for this system. I see 15 sites, or sets of frequencies, listed for this county's system. Do you want to receive from just one site, several, or ?
Let me use site 001 as an example (Thompson Peak, Scottsdale). It has 14 frequencies listed, but only TWO of them are identified as control channel frequencies. Now let's use bank 0 of the scanner for this site. In channel 000 of the scanner program
859.2625 and in channel 001 program 860.2625. Set the MODE of each of those channels to MOT. Set bank 0 to MOT. Now program in whatever TGs you want (as it appears you have already done) to hear. If you only want to hear the TGs you've programmed, set the bank to CLOSED. SCAN those two frequencies and you should be running good.
If the above does not work, and you've programmed it correctly, the likely reason is that you are not receiving the control channel frequency well enough. You should be able to put the scanner in MAN mode on either channel 000 or 001 and hear the control channel noise. While there the 4th line of the display will give you an indication of how well you are receiving. I've found you need at least 25% for decent reception and ideally should have above 50%. If you don't get a control channel signal, you need to use a different site's frequencies.
Note that trunk tracking ONLY works in SCAN mode, not MAN mode.
