Ok, I'll attach my current (as of this post) list of what I've got. Mind you it's somewhat of a haphazard mess I suppose, there's some info preceding the list - more of my infamous rambling I suppose - with the basic methodology I've found. Now, the issue for me is identifying actual talkgroups since I spent most all the past 2 weeks just looking for anything at all and recording the frequency then the color group because I figured I'd go back and do more focused monitoring to try and pick off the actual group purposes. Sometimes I get lucky and it's easy, most times it's not and all I can work with is whatever the hell people are talking about, but I'm sure some of you know exactly what I'm going through with this process.
I don't have access to the RRDB database, sadly, so this is a cumbersome process looking for the proper emissions per license - the FCC site doesn't allow for searching by emission types which would make things much easier I suppose (at least not that I've been able to figure out).
Anyway, the text file is attached, might be useful to some, might not but there it is.
Now, I'd like some help with something if anyone here in Vegas is able and it's regarding the Luxor NXDN system. I've looked at the FCC license info and based on the emissions they have 7 frequencies they work with (the repeaters):
Funny thing for me is that I'm not picking them up at all
on those frequencies, What I am getting is just off those, at very odd frequencies - and I know the first thing you'd to me is "Your SDR isn't calibrated" and I'd say yes it is: the most active single frequency I've picked up is supposed to be 463.60000 and I'm getting all the traffic on 463.59750 - I can't lock down the specific channel spacing on this system to save my life but 463.59750 matches a 7.5 kHz spacing assignment - I use 2.5 kHz for scanning anyway so it falls right on it.
Also, if you're thinking my SDR isn't calibrated and I said that it is, the reason is that I have the Fremont Street Experience at 464.10000 (just a hair up the scale) and also Trump International Hotel at 463.33750 (just a hair down) and both of those are locked in rock solid just by moving up or down the band (rolling the mouse wheel) - my tuner has a 57 ppm offset when it's warmed up and it's pretty much always warmed up so drift in this situation isn't an issue at all.
I'm simply not getting Luxor on their exact assigned frequencies at all and I'm hoping someone else can check that out so I know I'm not going insane.
I've tested this with both of my RTL sticks, one with the 57 ppm offset, one with a 50 ppm offset, and I get the same exact results with each: where Luxor's license says 463.60000, I'm getting them rock solid at 463.597500 every time.
I'm also getting NXDN traffic at:
463.62250 (could be Engineering)
463.62750 (sounds like Housekeeping calls)
As noted in the text file, I'm in downtown Vegas, just off the geographic center, in an apartment building on the 3rd floor with no outside antenna capability so I'm using either my Diamond RH-C77A for the VHF/UHF stuff since it's tuned to those bands or my trusty Radio Shack 800 MHz for the 800-900 MHz bands. The distance from the Luxor could be an issue for me but I can't believe the shifted frequencies are the result there.
I've spent time searching for anything else and so far this Luxor system just seems to be the only NXDN one so if anyone else can tune those frequencies above (the actually licensed ones, 7 in all) and tell me if you're getting hits I'd appreciate it.
