461.5625 DMR

Post by OceanNora »

For the past month or so I've been picking DMR traffic on 461.5625 with a Color Code of 11. Reception from the Revere area has been marginal but so far I've been able to pick up TG 27 Timeslot 1. What traffic I could hear strongly leads me to believe that it's a hospital security/operations channel. I've heard people coming up from radiology, "Alpha's all secure," and someone securing the ED (I assume the Emergency Department) and chapel. I know that both BI Milton and Good Samaritan Brockton have channels listed in the Wiki under that frequency. Both are in the wiki as analog with the BI Milton frequency being confirmed much more recently (12/20 vs 2/12) but given how little traffic I've heard so far it could be either. If someone closer to the South Shore could monitor I feel like this should be pretty easy to ID.

Only had CC 15 heard from Weymouth back in December, and in my to sit on it more list [bumped up in schedule just for you]

CC 11 is there in the weeds, and not able to get a better direction with the beam as CC 15 pops up at the same time

I don't think I've caught this before maybe February, so it makes sense that you only would have seen CC15 (Harvard School of Public Health) back in December. I appreciate it, I'm interested to see what you find as you're closer to both Brockton and Milton than me.

Since you are closer to the Harvard site, it does need an updated reconfirmation as the only thing I get is the beacon not TG's even when left on over a 24 hrs period from my QTH

Last we had for Milton was still Analog and using 900ISM, I know the Chief up there and will touch base with him over the next few weeks

I am line of sight to Brockton from my house and can pick up most of the UHF DMR and conventional users in the city. Including both Good Sam and Brockton.
I haven't heard a peep on this from my house with the UHF antenna.

We asked the top 3 people their answer. "Who is the user on the frequency above?"
Top Answer... Survey Says

BI Milton. Got it in the parking lot, close called on one scanner and no antenna on my SDS-100. The communications of "The Reedsdale Entrance" prior to my arriving should've been a sign.
It is a catch all hospital operations channel from what I heard today.

I knew we'd figure it out eventually, excellent work by all. Are you still only seeing one TG on the frequency?
