G4 Question - Conventional and Trunking Frequencies and 1-8 Zone Assignments

[ScottPDX]

I have looked at everything FAQ wise, and other stuff, but I'm not absolutely clear yet.

I know that G4 is single band. So I assume that if I want to listen to a conventional frequency on a G4, I have to assign one or more conventional frequencies to 1-8 of the rotating "channel?" selector, correct?

And these conventional frequencies on a G4 are limited to 700/800: 763 - 776MHz and 851 - 870MHz

And can someone explain to me how a zone corresponds to the 1-8 rotating "channel?" selector?

And how does 1-32 or 1-64 zones work on P25 trunking and conventional?

Thanks in advance.

A Zone has up to 8 positions using the knob selector on top. Meaning a zone can have 1 know selector position or up to 8.
You can only program in conventional freqs in the units frequency range. So in the 700/800 band and with out pulling up exact specs what you put down looks about right.
When programming in a knob position for the specified zone, you can select trunking or conventional but not a mixture of both. You can not scan across systems. If a system has multiple sites then you can only pull in traffic on what ever site the pager locks on to.
You can scan conventional channels. But first you have to program in 1 conventional channel per knob position. Then you use a totally different knob position to enable a scan list of the previously programmed in channels.
So in essence you have zone 1 position 1-8. I dont like to call it channels 1-8 as each knob position can have a conventional or trunking scan list of multiple "channels, aka conv. freqs or talk groups.

Just think of each zone/knob "box" as a scanlist (or maybe "mini-configurations" is a better description)

Each zone can have 8 "scanlists" (knobs)....

I think the latest PPS allows for 64 zones of 8 knobs/scanlists - so you can have up to 512 "scanlists" - but only one can only be enabled at any given time.

Each "scanlist" can contain one of:

- a trunk system with 1-64 talkgroups
- a conventional channel, or a list of (up to 16) conventional channels (to scan), or
- a selective call config (tone alerting).

(there are probably some other options but these are the key ones)

You just can't mix these things in one zone/knob.

Hello everyone,I just got my G5 pager and i have Indpls public safety programmed into zone 1 and all 1-8 positions filled,can i add more TG into another zone and fill the 1-8 positions for example zone 2,my 2nd question can i add a completely different site for example i want to monitor SAFE-T can i have 2 different sites and if so can i scan both sites?Thanks

 

[troymail]

can i add more TG into another zone and fill the 1-8 positions for example zone 3

Absolutely.... and many zones after that...,

my 2nd question can i add a completely different site for example i want to monitor SAFE-T can i have 2 different sites and if so can i scan both sites?Thanks

Yes -

You can create a "system" in Tab D2 that contains one or more "sites" and use that in a zone/knob configuration. The pager will look for a control channel on one of the those sites that is of acceptable quality (not necessarily the best nor the closest).

You can also create more "systems" and only have one specific site programmed into that system and use that in a different zone/knob. This would allow you to select that zone/knob and force the radio to try and monitor only that site.

Lots of options...

This really explained it well and straightened me out after my first attempt went horribly wrong. I had placed each single knob position into their own individual separate zone for a single wanted TG. Of course, the result I received was “Unconfigured” for each of the 2-8 knob positions. After I followed what you said above, I realized it is required that I have one or more knob positions in the same zone for each knob position single TG.

Thanks,

Thanks Troymail,its set up and working flawlessly .
