Programming for simulcast P25 systems/sites

[19sargeusmc56]

So with systems that share a core, how do you setup the different sites? Do you define every site in the simulcast system with RSSI/SYSID's or do you just use FF/FF?

How does this G5 decide what site to latch onto?

I never use the wildcards because none of the systems local to me require it.

On some knobs I use all sites for a wide area system, for other knobs I use the sites in one county, and then will also use one site per knob. It all depends on what control you want/need.

The G pager will lock on to a site with an acceptable quality of decode, then stay with that site until the decode deteriorates.

For my local TG's I use the site numbers required. Regarding simulcast, it "just knows" what to lock on on those systems. The only times I use the FFF stuff is for one or two of the knob positions I have set up for roaming scan type stuff, but honestly hardly ever use it.

An example of when wildcards are useful is when the various sites having differing sys-id’s amongst them. This presents an issue for PPS and wildcards get around this.

So the suggestion would be, rather than program 3 sites, all with different sysid's, it would be better to program 1 site, listing all channels from all sites, and use FF/FF?

I'll be honest I'm not sure what you're asking here. My simulcast county has probably 6-7 sites, I put in the control channel's listed and poof, it just finds them. Perhaps if this wasn't such a mystery and you told us what you were trying to actually receive it might help us help you.

I would only use one site per knob position. I tried 2 sites on one knob and sometimes my G4 would latch on to one site while all the action was on another. These are simulcast sites.

Unless I am doing some traveling and have some kind of "wild card scan" thing going on, I absolutely agree with this. I am confused by what he is asking in the OP. He mentioned simulcast and a core site or something but then goes on with something else. A little clarity would help to answer the question.

I would not do it this way. May work, not sure. I would program each site on their own with correct values unless something about the site doesn’t work in PPS, forcing use of wildcards.
I import sites from a csv downloaded from RR.
Even if I used wildcard value I would keep sites separate.
