Goffstown DMR Trunked System

#1 Post by TheDoza79 » 27 Sep 2018 01:14

WPKN959 Registered to Goffstown as a trucked DMR System

Frequencies:
159.360
159.840
160.305
160.485
170.150

Has anyone heard anything about this system or heard anything on it at all? I may be too far away from Goffstown to hear this system.

Those are the same five frequencies used by their old EDACS trunk.

Huh. Emission designators seem to indicate narrowband voice and data, but not 7K60FXD or 7K60FXE for DMR/TRBO. Of course, plenty of licenses seem kind of lax about that.

But a VHF signal from up on Mt. Uncanoonuc should have pretty nice reach, even if they're limited to 25W ERP. Programming my scanner with these 5 frequencies and sicking LCN Finder on it, it's yet to find anything. It's licensed as FB8 vs. FB6 so I'd expect a control channel to be running, but I'm not hearing one.

(Though to show how little I know, I didn't even realize 170.15 was available to anyone but Federal government.)

Actually 170.1500 is a Part 74 [Remote Broadcast] that Goffstown applied for many moons ago and was granted

Originally licensed for the EDACS as FB8's then modified to FB2's

Except within 150 miles of New York City, where 166.2500 and 170.1500 are both allotted for two way users.

FCC 74.402(e)(8)
(8) Operation on frequencies 166.25 MHz and 170.15 MHz is subject to
the condition that harmful interference shall not be caused to present
or future Government stations in the band 162-174 MHz and is also
subject to the bandwidth and tolerance limitations and compliance
deadlines listed in § 74.462 of this part. Authorization on these
frequencies shall be in the lower 48 contiguous States only, except
within ... 150 miles (241.4 km) of New York City.
There are several users in Southern New England on these.
166.2500, West Hartford, CT., Dukes County, MA.
170.1500, Windsor Locks, CT., North Adams, MA.

To name a couple.

Never should been allowed but alais it was.... I will note that they are secondary or maybe thirdley users to licensed Part 74 users who are actually secondary users to the Feds so in other words that can't complain about interference from them.
