![]() After all traffic is completed, after a few seconds the radios return to idle and are listening to the control channel for further assignments. Other units on different talkgroups will not. All units assigned will hear the voice radio traffic. When a call is initiated on the talkgroup that the radio talkgroup selector is on, all radios on that talkgroup are assigned an RF channel, and go to that channel. So what happens is this, all IDLE radios on the system are listening to the control channel. "Talkgroup" is a group of radios assigned to a specific frequency or channel by the controller, i.e., "Police 1" or "Fire 1". When I say "RF channels" I mean actual frequencies with a transmitter/receiver on them. I'll stick to Motorola systems as that is what I know and currently maintain.Ī "Trunked Radio System" can be made up with as little as 3 RF channels or 28 RFchannels, depending on the needs of the customer. I know quite a bit about trunked radio, since I have been working in that field for over 25 years. The email button should work this will take more "educating" than probably should be done here on NAT. Is it necessary to enter those multi-tables or will the scanner glean that information from the control frequency transmissions? I also see "multi-tables" with Low & High channels, channel offsets, khz steps and base frequencies. ![]() Is that what the HEX and DEC entries are all about? I understand the trunking uses subaudible tones such as the CTCSS tones. Can I simply enter the control frequencies without the Talk Groups (TG ) and Fleet Maps (FM ), or do I need to enter TG info? What about FM info? I've read so much I've lost track of it all. The Pro 96 documentation calls for "fleet maps" but I see no information for those on RR. I've printed up the WY info from (RR ) but I do not understand what all is involved. I've been reading up on the Radio Shack Pro 96 and the Pro 197. A neighbor and I have been messing with radios for years but this trunking thing is a whole new ball game our radio tech does not understand it. ![]() I see a thread from February about police scanners:ĭo any of you have a good source of information on the details of how the trunking works.
