VT statewide NXDN48 system

#1 Post by bfrederi » 18 Jul 2019 22:44

I was up in Franklin County, VT earlier this week and got in enough radio time to track down the following statewide NXDN48 system. I didn't have enough time, unfortunately, to track down TGs after I mapped out the channels/frequencies. Just enough to discover that the vast majority of the traffic was encrypted.

The system belongs to FleetWave Partners out of Williston, FRN: 0021239736

Only two out of the eight sites could be heard from Saint Albans Bay. The others didn't show even the slightest signal in SDR#.
Site L111-01 was clearly out of Saint Albans. I believe Site L111-15 was coming in from Clinton County, NY, across Lake Champlain, though the licenses indicate that the transmitters might also be located in Burlington, VT. The LCN, RAN, and NL data come from DSD+. Locations come from the FCC database. Hat tip to Eric WB1HBU for his UHF LCN-to-frequency mapping posts on RR, without which it would have been impossible to sort this stuff out.

The licensing for this system is as convoluted as ICE and Comtronics is down here, with a different license for almost every frequency, but most licenses also covering several apparently unrelated frequencies.

I hope the formatting below is readable once the forum software has its way with it.

I would guess that the 803 one may be a 6.25KHz channel. That company is licensed on several at different locations
463.91875 Monkton WNRC544
462.94375 Jay WPSF520
463.29375 Jay WPSF520
463.94375 St Albans WPTJ887
464.86875 St Albans WPTJ887

These channels are often skipped in a search because the search default is for 12.5 KHz spacing. A close by system may show one of the adjacent channels.

Awesome, Chris. Thanks for that tidbit. I just assumed that it meant it would be north of 470 MHz.

Not sure when I will get back up there but I'm anxious to flesh out some of the missing pieces.
