Haven't Found Total RF the last few years but I just stumbled accross this https://www.sportsvideo.org/2018/01/26/ ... sses-away/ Anyone who has listened over the years knows how critical Jim Malone was to the set up efforts.

Hello,

Here are my notes based on the past couple of years. The radio shop is currently testing and the same plan is going to be used this year. Sometimes the talkgroup is called out during testing. The talkgroups are spread across the three sites and the sites do not appear to be linked together. I had no problems listening to the Hopkinton site with a discone on the roof over here on the North Shore.

Medical is split into 4 zones with A being at the Hopkinton start and D being at the Boston end.

There are additional DMR Simplex and DMR Repeater channels that I am too far away to receive.

Hopkinton Linked Capacity Plus
Site 1 (No adjacent sites)
453.0125 Color Code 15 Channels 1/2
451.5000 Color Code 15 Channels 3/4

216 Medical Division A (confirmed 2017)
251 Start Line (confirmed 2016)
252 Start Area (confirmed 2017)
253 HOP Busing (confirmed 2017)
254 HSP Parking (confirmed 2016)

Waltham Linked Capacity Plus

I think I just found Total RF? 450.825 and possibly 450.7125 appear to have digital modulation possibly DMR. Eric see what you find?

Eric it looks like Waltham may not exist anymore and Boston was another frequency.

Talkgroup 224 on the Boston site is still being referred to as "Vehicles". I'm hearing traffic on 451.700 and 461.675, but nothing yet on 463.550.

None of those frequencies are licensed in Waltham anymore than I can see. My guess is they went away with the Antico tower removal on Prospect Hill. We really need to read one of these radios.

Hello,

I still get the Waltham talkgroups, but I noticed Boston comes up for the site name. So it does appear the course talkgroups are on the Boston site.

On the OneVoice Connect Plus system, TGID 601014, 601012, 601013, and 601015 on Site 69 are listing leaders and times. 601015 was talking about men's wheelchair and 601013 was talking about females, but I'm not sure if there's any rhyme or reason to which talkgroups get used for which.

800MHz Trunked System:

32976 EVENTS-7 "Seabring Command" {calling squad units}. Maybe MA Army National Guard Ops. BTW: I believe they are saying "Seabring" or "Sebring" or something similiar.
33360 SOPS-1 "UCC" / Boston Command Post (CP)
33488 SOPS-2 "Hopkinton Command Post" (CP)
33680 SOPS-3 "UCC"
33904 SOPS-6 "DOD Command"
39952 DFS-EAST Heating Buses Dispatch/resource management
8496 ?? "Marathon Medical Ops". I found this via "search mode" so I don't have the exact talkgroup alpha tag.

MA Army National Guard:
142.5625 Rptr PL 167.9 Princeton Rptr
49.930 Rptr PL 110.9 Plymouth Rptr
49.790 Rptr PL 131.8 Worcester Rptr

It was relayed to me last year that MA Army National Guard Military Police detail officers were using VHF simplex P25 digital portables for ops. Maybe someone local to Boston can find that frequency.?.

I'm hearing a lot of key up's with MDC1200 push-to-talk id, so I'm guessing it's on the VHF system, as low band doesn't not typically use MCD1200. Heard several radio checks, but no real conversations. Obviously when the VHF rptr keys up, it keys up Plymouth & Worcester low band rptrs. Monitoring in Worcester Cnty, so I only heard talkgroups that are statewide broadcast -vs- local to metro Boston transmitters.

Hello,

The wheelchair talkgroups would be active first and further along the course than the other talkgroups. I did notice the press channels were not showing up on the Cap+ system. It appears they moved them to the OneVoice system to reduce loading on the Boston site. It makes sense as I doubt they have to switch to the Cap+ frequencies often.
601013 is either Womens Press or Womens WC Press.
(226) Mens Press
(227) Womens Press
601015 (228) Mens WC Press
(229) Womens WC Press

Something to look for next year, although the main ops are still on the Cap+ system.

Eric, Did you find any more frequencies in play. I ask because the license shows a couple more?

That would be CBRN. See-burn.

Chemical Biological Radiological and.... errr..... and..... Nuclear?

Something like that. HazMat in other words.

Actually, it's CBRNE, Chemical, Biological, Radiological, Nuclear and Explosives. You are correct on the pronunciation. "See-burn"

Might have been guys from the FBI, I volunteered at an amateur radio op and was posted in Wellesley Sqaure, couple times there was some FBI WMD guys walking back and forth along with the MA ARNG MPs and two cops. Only reason I know they were FBI is some were wearing plate carriers with the FBI insignia on them, others wearing jackets with FBI WMD ID patches.
