PPL NEXEDGE96 Wide Area TRS

[Septa3371CSX1]

While in Emmaus yesterday I found a couple NEXEDGE96 control channels on 451.225 and 461.3875. I found a PPL license with 451.225 on it (KYL340 (PPL ELECTRIC UTILITIES CORP.) FCC Callsign Details) but can't find a corresponding license with the other frequency on it. The only thing close I found for 461.3875 was one for Robert Conway. This system was coming up as Network L264. Here's what I have for it.

Site 23 RAN 23 NL 11 12 22 26

99 = 451.225

Site 26 RAN 26 NL 22 23

444 =
512 = 461.3875
609 =

If anyone can confirm if I'm on the right track here please chime in.

Hello,

You need to find the additional frequencies used at each site and find some more sites. It first appeared the system was using a common NXDN map.
LCN 1 through 400
f = (lcn - 1) * 0.0125 + 450.0 MHz
LCN 401 through 800
f = (lcn - 401) * 0.0125 + 460.0 MHz
Anything 801 through 1023 would be a custom channel, likely T-Band.

However:
444 calculates out to 460.5375, which is licensed to fire departments.
609 calculates out to 462.6000, which is a FRS frequency.

So it is likely they are using a custom map, which will make searching for frequencies more difficult.

You probably are on the right track. A few things I noticed about PPL licenses -- Most of them are non-trunked (but appear to likely be used for trunking). Most VHF-HI/UHF have 4khz emissions designators. They have many recent VHF-Hi licenses.

I'd have to wonder if they wouldn't be using a VHF for some sites and UHF for others.

If you are interested, here is a Google map with all PPL VHF-HI / UHF locations and callsigns.
