I checked the previous mentioned locations, along with data from Sites 7, 14, 16, 23, 28, 29, 31, 39 and so far, nothing has shown up. I'm thinking it might be somewhere near the Delaware River, kinda like how Sites 36, 37 and 38 are set up. (?)

The previous control channel for Site 21 was 773.60625 (7TAC72), now 774.60625 (7TAC74). Both of those are nationwide interop frequencies, and both are licensed under the site's waiver to use them for the mobile site under WQQS714.

I don't think it's a fixed site. Has anyone ever confirmed the mobile Site ID in the past?

I always had the mobile site as Site 40. Not saying that's absolutely definitively correct, but that's what I had it nailed down as.

Question based on your hypothesis though GTR. Just playing devil's advocate here. If it is not a fixed site, is it possible they're now using a mobile site for basic range or feasibility testing before erecting a permanent site in an area?

Had you actually decoded the mobile site in action at some point? I didn't think that anyone had actually caught it on the air, since the RFSS/Site in the database was just a placeholder and no one had ever submitted updated data to correct it.

There's very good modeling software that is used for that purpose, but never say never. Technically the state is permitted to also use those nationwide interop frequencies for a temporary fixed site (in addition to the mobile site), although there are restrictions on height of transmit antenna, power output, etc.

I could certainly be wrong about Site 21 being a mobile site, but that's okay, that's part of the fun of figuring this stuff out. It's just odd that within the past few weeks, the adjacent site list for Site 21 has changed drastically, it's using those interop frequencies that are intended for the mobile site, and no one seems to be able to get a lock on the Site 21 control channel, wherever it might be.

Hell, it could very well be a figment of everyone's imagination. Perhaps just a "site" they've added to the zone controller that doesn't actually physically exist yet.

I figured there was no harm in having Scott update the mobile site in the database to 21, along with flagging the two frequencies that have been noted as the controls per the peer lists. Worse case we change it back to a dummy site if Site 21 turns out to be a fixed site. Sorry, Scott...I'm always making more work for you! :D

Im trying to program a unication g5 for MONOC and having issues. On the site numbers in the database, do I use the one's int the ( ) or the regular one. The pager says it is out of range on all the sites.

So what site are you trying to use and where are you monitoring that site from?

Also double check the System ID and WACN are correct.

Is there a concise list of what municipalities, agencies, and or talk groups are normally on each of the sites?

I had, and traced it to being, at least in that instance, being operated from the big Freightliner UCP truck (9001A I think it is?) when it was at the Meadowlands for an event. But they could have just been using that as a placeholder themselves. Again, I don't guarantee it's right. It may not actually even have a fixed site number to be honest, and there may be more than one "unit".

And the program works very well. I was just playing devil's advocate and throwing an oddball possibility out there. REMU has done stranger things.

I honestly think there is or will be a fixed site 21 based on various pieces of information out there. It may not physically exist yet, but the evidence several people here have presented make it appear it's at least planned. And the coverage in that area where it was believed to be is kinda spotty.

Sorry, Scott...I'm always making more work for you! :D

If he hasn't strangled me yet for submitting corrections to typos, grammar, and never ending municipal changes, I think you're good. :D

NJ ICS Site 21

Thanks to the Summer time band opening early this morning, I was able to get for exactly 2 minutes a signal on Site 21 from the southern Edison NJ area. The following was observed on Unitrunker:

773.60625 alt.
774.10625 alt.
774.60625 control
NAC: $390
Peers: 3, 4, 5

So this data tells me that the location is probably in the Burlington/Atlantic/Camden County border area. I'm thinking it's possibly in the area of Red Lion or a prox. of a 10 mile radius. Can some of our Southern NJ monitors check for signal strength to nail down the location of it?

Edit: After reviewing the affiliations log, it appears that all talkgroups that attempted to join/affiliate to Site 21 were Denied.

Frequencies match up with the national interop licensed for the mobile site. Good catch, at least we have some concrete data that something is on the air with that site # and broadcasting valid data.

Imagine if an NJICS Engineer came on here and just told us everything. That would be too easy.

What would be funnier is if they were moving the mobile site around and laughing as we try to figure out where it is. I would do that if I worked for REMU.

Interesting as this morning I am decoding an LT system on that National frequency. The RR data base has nothing for NJ NY or PA. Take a look.

I don't think anyone actually has a full "plan," per se. It's an evolving system. What makes it hard is that the state use frequencies are geographic licensed. You won't see them in ULS. Maybe a search of CAPRAD would get the use plan?
