DTRS Zone 4 (El Paso County) Site Locations

[soncorn]

I was going through my programming for an upcoming trip and I noticed that a lot of the site locations listed in the database seem to have changed dramatically.

It seems that some of the current site locations listed also don't make sense (no towers) and/or are not even close to the location listed on the license.

Can anybody verify this?

Thank you

Edited to add: I will submit what I think are correct coordinates, licenses etc. I just want to check with people in the area first.

I looks to me that who ever did the mapping did it for the gps enabled scanners, giving a center point in a population center rather than the actual tower site. I seem to recall a discussion on this a few months ago here.
If you will drill down a layer on the site in RR the actual tower location will show up on the license information page.
I made mention of this on my DTRS Mapping project thread down a ways...

That was part of what drove me to check on this. I keep a Google Earth location for each tower site so that I can visualize the locations better, etc. (I was going to share this when I finished updating it, hopefully today)

Periodically I go through and check for new sites. This time I was updating zone 4 and noticed all the differences.

I think that we (or whoever gets to make the decision) need to decide to either do the tower location or the population center. Personally I think the tower location is better. If we want to put together things for the different population centers (counties, towns, cities, etc) then so be it, but that should be separate (maybe in the wiki).

The location shown in the site should reflect the area it is intended to cover rather than be a point at the site with a circle around it showing what area the tower covers (Lindsay's rules, not mine, but I agree with this philosophy). As mentioned earlier, the purpose of this is for the GPS scanners, because after all, we're in the business of taking care of programming scanners via web import

Generally, the DTRS sites should be at the site location (or somewhere close to it where I don't have specific coordinates) and have a 25-50 mile radius for the site coverage. Other systems, such as the metro EDACS systems, will be covering the jurisdiction for that system and not be a point at the tower location with a huge radius.

The FCC data for that site should give the viewer a better picture for the actual system component locations if they desire to know about it.

Are there specific DTRS sites you want to discuss? There are a few out there which I don't have good coordinates for so I eyeballed roughly where they should be based on other map sources and went from there.

Believe Bruce has included all DTRS site coordinates in his most recent excellent mapping revision.

Sites 4-011 and 4-022 would be good starting points. The database locations are nowhere near (more than 20 miles away) from what I believe are the locations listed on the FCC licenses. I believe that WPHK775 is the license for 4-011 and WQAD254 is the license for 4-022. If that is correct then the locations are pretty far off, if the licenses are not correct then I am wrong.

There are two fixed locations on WPHK775 and three on WQAD254. Which location on each of these licenses do you believe is the correct one for these sites?

[n0nhp]

The three site listing is three physical sites in simulcast. I am not sure why the engineers did this but all three towers are in my map.
I have not spent the time looking at the two site license and studying it. I'll take a look and see what I see.

It looks to me like the three sites for WQAD254 are 4-019 (site 1 in the license), 4-017 (site 2 in the license) and 4-022 (site 3 in the license). I am basing this off the frequencies listed in the license and in the database.

For WPHK775 the two sites listed appear to be simulcast sites. Site 1 in the license appears to be site 4-011 in the database and site 2 in the license appears to be 4-013 in the database.

I think maybe some new pro96com tower files need to be run or something, because the listings in the database just aren't matching up for me to what is in the licenses.

Thanks, fixed for 4-011 and 4-022. There's not any simulcast in El Paso county, they just put multiple sites on the same license (some with the same frequencies).

Okay that clears it up some, that is why I wanted to check with the people in the area.

Sounds good, thanks for your help.

And enjoy your trip...it's beautiful here this time of year.

I have 29 Freq.'s for El Paso County and Colorado Springs. Are these the right Freq.'s to have in? If they are not right could someone send me the right ones?

Don, El Paso County acts just like the DTRS now with control channel trunking so you certainly don't need that list only CC's let the scanner do the work from there.
