Douglas Fire VHF

#1 Post by sawyer100 » 08 Aug 2018 18:09

All:

Just like I predicted, someday the leftover towns on lowband finally got it together to leave low band and get a real radio system (i.e. VHF repeater).

KAY985
Douglas, Town of - Fire Dept.

pending level II - in the FCC:
154.7475 Repeater (same location, a monopole cell tower, as their current 33.960 FB & 460.2125 low-powered rptr)

as far as Fire District 7 (southern Worc Cnty) goes, fire depts don't use UHF, they are low band or VHF.

Unsure when they switch will be made. As of today, still nothing on the 154.3625 Northbridge Fire VHF rptr.

I heard some chatting on Northbridge Fire 154.3625R with a pl of 151.4 a few months back.

I'm hearing Douglas FD on 154.7475 123.0. It appears to be patched to low band from the brief transmissions I heard.

It is a temporary, low power patch on temporary equipment at a temporary location. Future full build out coming.

Any idea if the PL will remain the same?

I'm confirming of as this week, the fire trucks are using low band, and fire fighters are using UHF hand-held portables talking to the UHF fixed site 460.2125 D-503 repeater on the monopole tower site, so no VHF radios (i.e. mobiles/portables) are being used as of yet... I will advise when they are actually using VHF radios. As a former example, when Uxbridge Fire switched off low band to VHF radios, they stopped using their UHF hand-held portable radios (i.e. mobile repeater) and started using VHF mobiles & VHF hand-held portables full time, etc.

Don't forget Mendon and Grafton Fire are the exceptions and do use UHF.

I'm waiting to see the FCC license modification for Mendon Fire, as they already had plans in the works to switch off UHF, on to a VHF repeater.

Re: Douglas Fire VHF (Sutton PD simulcasting on Douglas Fire VHF)

#10 Post by sawyer100 » 26 Nov 2019 17:09

just wanted to report that the past 2 weeks +/-, I have been hearing Sutton Police simulcasting (i.e. transmitting) on the Douglas Fire VHF channel. This is on a daily, full-time basis.

What a have noticed new about Sutton Police is:
* they just got a brand new police station, moved out of the former location. This means a new dispatch console & police station antennas.
* the most recent change is that "Station S" (i.e. PD dispatch) now has a push-to-talk ID (i.e. Motorola MDC-2100) when they talk now. Cruisers & hand-held portables do not have any MDC-1200 PTT ID yet.
* I have been hearing Sutton PD simulcasting out Sutton Fire almost on a full-time basis, which I found odd. and then 1 day after the discovery of this, I started hearing Sutton PD simulcasting out the Douglas Fire VHF repeater frequency (of a different signal strength). Matter of fact, I will have to see if Douglas Fire is still on this or not.?.

Are you sure on this Mike?

We monitor all 4 channels 24/7 and while I can confirm there has been A LOT of PD/FD simulcast lately on the Sutton channels even when its not a fire related call, I have not once heard sutton dispatch on the Douglas Fire VHF. If they are, it is not making it through the repeater. I've also not heard an MDC coming from Sutton dispatch on PD or FD. Are you hearing a leading or trailing?

Douglas dispatch simulcasts onto the Douglas PD and FD when they have a fire call. They also have a trailing MDC of 0775 which coincides with their call sign of 75.

I will double check on Wed. After my last post, it's apparently being transmitted from the new Sutton PD station (simplex only), and not from the Douglas cell tower site (xpatch). I've been hearing Sutton PD on Douglas Fire 154.7475 PL 123.0. So when dispatch simulcasts on FD & PD, it's also transmitting on the Douglas Fire VHF (simplex). I'm guessing it's probably low power. When I do hear it, I will drive to Sutton PD (when I can) and confirm it originates from there. The Douglas cell tower site gives me full scale signal (5 of 5). I'm only getting (0-1 of 5) bars when Sutton talks. I will also check to see if my scanner is falsing (all my scanners share the same base station antenna). I have already tried 1 scanner on Sutton FD & 1 separate scanner on Sutton PD to confirm simulcast, yep. I then toggled a 2nd scanner to Douglas Fire VHF and it was coming out there, but that freq is only signal of 0-1 of 5. Sutton FD & PD come in 5 of 5.

Just rang a bell:
1) to clarify my version of "simulcast", is "only the dispatcher" is broadcasting outbound, not the cruiser/PD traffic inbound. this means console related.

2) the same time I'm hearing Douglas Fire VHF is coming out from Sutton, the dispatcher is also simulcasting out on Sutton DPW too (46.520 PL 123.0). When I don't hear traffic on Douglas Fire VHF, there is also nothing on Sutton DPW low band as well. Maybe the new dispatch console is accidentally simulcasting out various channels it has access to, and the dispatcher doesn't know it .?. The DPW freq was yapping police traffic stops, etc all night (after DPW hours). also console related.

Wed, 11/27: I guess their radio techs must read this website, because as of 2pm thereafter, there has been no more "multicasting" out on Sutton Fire, Sutton DPW low band & Douglas Fire VHF. I did hear some transmissions earlier today (prior to 2pm) of "radio service testing", and I heard that on Sutton FD & Sutton PD, and Sutton DPW channel (all separate transmissions, not multicasting), but not a peep today of them transmitting on the Douglas Fire VHF. So obviously the radio tech shut off that multicasting feature, as it was multicasting prior to me hearing him on the radio today.

I agree with your #1 when we have heard it on Sutton PD and FD and also agree with your assumption on #2.

Glad to hear it sounds like the resolved it. If they were on Simplex for Douglas FD Low Power we wouldn't have heard it and its likely the did the same I did, put the frequency in simplex initially while waiting for formal info on the input which is now known.

thanks Greg. glad it was fixed. I will let everyone here know when Douglas Fire switches over to VHF radios -vs- low band mobiles w/ UHF hand-held portables). I keep track of what everyone transmits with (meaning frequency band).

I've been listening to these channels for a couple days. It seems that when talking to a police unit, the dispatcher only comes out the police channel. When talking to a fire unit, about 90% of the time I can hear the dispatcher on both the Sutton police and Sutton fire channels. I only heard DPW traffic on the DPW channel, and I only heard Douglas FD on the Douglas FD VHF channel.

I'd guess that they are doing this so that the police officers know when the dispatcher is busy dealing with a fire incident and they don't bother them, but I did hear a few instances where it caused confusion.
