DH Med Center Security & Maintenance

[rja1]

Got the Stat Flight VHF frequency, but don't see much else in the Grafton county listings. I did find this from a bing search of DHMC frequencies:

FCC Callsign WPNQ916 (DARTMOUTH HITCHCOCK MEDICAL CENTER)

FCC Callsign WPNQ916 (DARTMOUTH HITCHCOCK MEDICAL CENTER)

I think the emissions designator 7K60F7W appears to be DMR conventional & 11K2F3E is analog. Looks like a bunch of UHF repeaters with a 5 mHz offset. Each DMR pair has a matching analog pair.......maybe a back up in case the DMR pair goes down??
Anyone monitoring any of the following pairs of frequencies?
451.8875 / 456.8875
452.3500 / 457.3500
452.7000 / 457.7000
461.5750 / 466.5750
464.8750 / 469.8750
451.3000 / 456.3000
451.9875 / 456.9875
451.5000 / 456.5000
452.1500 / 457.1500
452.6625 / 457.6625

I'm about 6 or 7 air miles away from DHMC. Any info on monitoring DHMC greatly appreciated.

You may be in the best location to report out findings. These sites rely on folks in the area to help with information.

If I remember they run a DMR trunked system. I can say I added 451/456.8875 to their license a few years ago. We always licensed everything for DMR and analog. Would only add NXDN or P25 if needed. But since then I think they may have changed vendors.

I'm not so sure about this being a trunked DMR system. There are 10 pairs that show as DMR. Those 10 pairs show up again as analog (FMn) Just about everything else shows up as mobile units. I'm still thinking these pairs are conventional DMR repeaters.
If some were control channels, why would all of the pairs be spaced 5 Mhz up?
Just picked up a Diamond F23H & once that goes up on the roof, I should be able to hear everything......hope it's not encrypted.
Once I can confirm what's what, I'll submit them to RR.

reguardless of conventional or Trunk, the input frequency of UHF Part 90 licenses is + 5
Based on the license, you only need to put in the 451/452 frequencies [FB2] which are the Repeater outputs
