As I have been playing with Unitrunker trying to solve a weird problem, one of the things I noticed is that Lake IR (site 18) freqs are very different from what is in RR database.

The list as shown in radioreference db:
851.4250c
853.8875a
853.6375
853.9625
853.9875
854.1875
854.2875
859.0125
859.1625
851.7500



This is what Unitrunker sees (and they are all quite active):
853.8875a same
851.4250c same
851.1625 new
853.1625 new
853.2125 new
853.6375 same
857.4375 new
859.1625 same
859.4375 new
859.5625 new
851.7500 same

My real question is not so much why the RR db is incorrect, but how recently was the site totally changed and more importantly, why? Is this part of the P25 prep work?

Between the lines
Check the fcc license and see what was newly added/removed and you'll have the answer.
It's good to assume the frequencies were recently added and might need to be submitted to RRdb

Utah County has TWO simocast sites: Lake Mountain Simo (7202 Site 18) and Utah Simo (7202 Site 4) which the UCA techs are calling "Happy Valley Simo."
Not sure on Site 4 but I believe it hosts four sites at Kimball Tower (BYU), East Lehi, UC Jail and West Mountain.
Site 18 hosts two sites (that I know of) on Lake Mountain and Cedar Pass (Eagle Mtn.) There may be more but I don't know for sure.
This all took place a couple of years ago or maybe sooner because of growth and coverage issues.

Yes, its been years since I did any site research. What I'm finding is that what I thought was Lake IR (Site 18), seems to actually be a north lake area Simo site with 3 sites:
WQED799 East Lehi, mouth of AF Canyon
WREL966 Hills above The Ranches (Cedar Pass Ranch)
WPRH431 Top of Lake Mountain, although this site only lists 5 of the 15 repeater freqs - not sure how that would work to carry simo traffic.

The BYU Kimball tower site seems to be officially part of the 643E system -Site 30. It is a very quiet site. I'm not sure what the difference is between 7202 and 643E any more. They seem to use them as the same system.

I take that back, at least the FCC records show Kimball tower as one of the simo sites with 852.6625 control channel. Not sure if that is still the case, but that is what's on file.

Technically 7202 is zone 1 north zone and 643e zone 2 south zone, why they put site 30 Provo in zone 2 is beyond me, anyway in regards to a site that the frequencies don't match either the database or the fcc license, I've had that very issue with the new horn site down here, the frequencies don't match the license, I probably did something I shouldn't and emailed the UCA tech guys to make them aware of it, in case it had gone unchecked, and now they have been on astro 1 & 2 encrypted since I emailed them.. Anyway I do know of discrepancies in the frequencies.. I try to make sure the stuff is correct and updated but I can only hear 4 sites where I'm at... And don't get to salt lake or Provo that often

All I can suggest is find out the frequencies and submit a correction , and check the doc license to make sure it hasn't been changed

Years ago when 7202 was being set up, it was quite common for them to move frequencies around as needed and fix the FCC paperwork later. I was told the FCC was fine with after-the-fact paperwork updates. Ever since then I don't rely on FCC records for site info. I just used mtrunker to map the sites (now Unitrunker).

Are you saying there are 3 zones in Utah County?
1. 7202 site 4 UC Simo "Central" 852.6625 control
2. 7202 site 18 "North" 851.425 control
3. 643e site 30 "South" 851.575 control

It seems right, I just never realized they were doing it that way.

The 7202 system , is a zone, it’s zone 1, mostly north, 643e is another zone in the system mostly south.

I've mentioned it in other threads and have experienced this frequently. It seems if a user comes roaming on a tower it drags along the previous frequency into UT. This posts a new freq to the site I'm monitoring - keeps 1 user on that freq forever - so I usually delete this freq from my map.

Question is do these freq's reappear after deleting them and are their active radios using them constantly? If this is the case then enos is correct - submit it to the db admin for correction and we can all give feedback as to whether it is working correctly.

As users travel the state, their radio registers with each site its near, what ever channel they are on will be broadcast on that site, (I use unitrunker and see this all the time) some radios are denied access on that site while others are granted access. Someone from my area goes up to salt lake still monitoring price dispatch, it will follow them clear to salt lake unless they change channels, each channel they change to registers on the site, some are allowed while others are denied access, depends on what that site allows and what radio it’s coming from.
