I used center of Seminole County, 20 mile radius, found 377 unique frequencies in Private that have a licensed emission designator indicative of DMR Fixed Base station.
EDIT: In spot checking, it looks like some of my location data is out of sync. I'll work on that, today.
I was wondering about that.
I also noticed a few oddballs that seemed off a ways but figured it may have just been an erroneous DB entry when the info was submitted by the licensee or whomever the frequency coordinator was.
Sorry Paul, I did not write down the few that seemed off but can probably recreate them if you need them.
For the most part, most of the results I did get from your latest SS version were pretty darn close!
I assume your info is taken from actual FCC coordinates and not what is shown in the RR database here correct?
I know for a fact that I've found several FCC licenses where the station or control point are listed in error at the FCC site.
They are mostly older licenses that have been around a while and maybe when they did not have decent tools for calculating exact coordinates such as what can usually be obtained with a decent GPS these days.
Back in the old days, a lot of coordinate data was input from topo maps from what I could tell when looking at very old licenses that may have not had the true coordinate data updated when the licenses are updated.
I usually rely upon the stations control point city and county for those I know do not display accurate coordinate data at the FCC site.
One would think most DMR licenses do have accurate data but I guess some of the old users simply changed their emission designator and did not pay attention to the coordinate data that the coordinator would have input for them.
That could be a daunting task for an FCC staffer to go through each license and confirm coordinate data is correct!
I bet they will though as things start filling up and they need accurate data to avoid interference from one user to the next.
I know with narrowband rules on VHF, the FCC tries to not setup a new NB user right next to a user on an old wideband channel even if everyone is now showing narrowband emissions or not. There are already some cases where they have had to do that though as the band it pretty darn full in some cities that they have no choice.
Service specific channel may also be using the newly created NB channels as well. Railroad is a good example of some new licenses being granted on some of the new NB only frequencies.
I do wonder how some of the radios are handling it especially if they don't really have good selectivity.
All modern radios from decent vendors should handle it but some of the older radios that had the NB setting may not have the selectivity that is really needed.
