Staying at the South Point for a few days.
Uploaded the four LCN System Frequencies for the South Point
from the RR database into my Uniden 396XT.
001 (1) Confirmed LCN 01 454.30625 06 454.31875 08 454.33125 10 453.01250
All I hear are digital signals - no voice.
Anyone listen to the South Point recently??
Did they change frequencies or radio systems?
Funny thing is that the actual current frequencies don't even come up with an FCC search for their license, either. The owner of the South Point property is Michael Gaughan (note the spelling of the last name) so I did an FCC search for "Gaughan" in Nevada and of course it came up with only one reference to an old expired license for the Barbary Coast Casino Hotel which is long gone for years now.
Then I chose the most "normal" frequency of those listed which is 453.0125 (for some strange reason if I added the last 0 I wasn't getting results from the FCC search, it only came up for me with 7 digits) and found 11 entries for Nevada, one of them being "Gaughn South" - yes that's how it's spelled on the actual license, incorrect as it is. The license I did find is WQKE961 and it only lists 2 frequencies altogether: 453.01250 and 458.01250.
Went back and did another search for "Gaughn" (the misspelling) and found several other licenses but the one relevant here is WPRJ762 and it's relevant because it lists 8K30F1E and 8K30F7W as the emission designators and that means NXDN communications hardware - oddly enough it lists totally different frequencies from the ones still used on the RRDB page for the South Point Casino Hotel. Guess that needs to be updated as well... they may still have the older LTR analog trunked system in use at the same time, I don't know because from my location in downtown Las Vegas I can't receive transmissions from South Point which is quite a ways off.
The only way to monitor NXDN would be using a discriminator tapped scanner or an RTL stick using SDR software (to control/tune it) and then piping the baseband audio into either DSD or DSD+ which would convert it into audible speech.
The license shows the following frequencies (repeater output with input being 5 MHz higher as usual):
452.4785
452.5125
452.6375
452.6875
They may still be using the older frequencies as well but the NXDN transmissions are licensed for those I just listed. Also, because of how NXDN can be used, you may not get the transmissions on those specific frequencies, they could be using the offset of 3.125 kHz (positive and negative, or some other offset since NXDN allows for several choices) to give them the two 6.25 kHz channels on either side of the assigned frequency. That means, for example, if you were trying to tune in transmissions that appeared to be at 452.4875 with a regular receiver you'd actually find they could be transmitting content on 452.484375 (-3.125 kHz) or 452.490625 (+3.125 kHz) or whatever depending on the offset.
The point is: NXDN transmissions don't happen directly on the assigned frequency so you most likely won't get content on those precise ones, it'll be above or below it based on the offset.
The NXDN license for South Point went into affect last July and is listed to expire in 2015; I'm sure they'll be getting another one at some point for an extended period - I think they're basically using the short term one to test out the NXDN hardware and see if it's worthy of long term usage.
So now you know.
ps
The Luxor (not too far from South Point) and The D (which is in downtown) are also using NXDN communications hardware, just for the record.
