460.425

[Cskib32087]

I was going back in recordings and found 460.425 DPL 343 booming in, looked it up and its a new CH for ansonia ambulance. a few people on it testing was all it was but they were talking about Northeastern communications changing out antennas and coverage.
So they might be changing over soon who knows

I had a conversation about this very same thing with the A.R.M.S.-Chief a few months ago at a training session we both attended. I believe this is going to be their new dispatch frequency and the current one will be either for secondary use or just dropped altogether, I forget which. I will email him and find out. Thanks for posting. I had forgotten all about this....

why do they need to change their dispatch frequency ?

Ansonia Rescue Medical Service (aka ARMS) currently operates on 461.4500 for dispatch and ops. They also have 462.675 and 462.625 (GRMS) which to operate from, but those were assigned to them when the organization was Ansonia Civil Defence and licensed through thier former chief. I beleive they had been trying to move away from those two GRMS frequencies (obviously assigned to them before they were made into GMRS by the FCC) for a few years now.

As for getting away from 461.4500, I am not sure. There may be an interference problem with the control-point repeater on the Hilltop or something with the line of sight radio down at C-MED who dispatches them. I can see if I can find out any information and I had heard some testing the other day on 461.4500 conducted from ARMS HQ (Station 3).

They have now switched over to 460.425 DPL 343 narrow band. Sounds good.
They have the same traffic runing on the old 461.450 but listening to the inputs they are on 460.425 and something is patching it to 461.450 with a short delay

I am getting it in portland fairly good. but i am getting a PL of 79.9 off my BCT15 and BC785D in tone search mode. But good find thanks for the info!!

Here is the answer you have all been waiting for!

Sorry for the long delay in getting back to everyone. I emailed the acting Chief of A.R.M.S. about the frequency change and inquired about any problems with the old one. I also inquired about the simulcasting that is taking place. Dave is a real nice guy to talk to, but very busy. Either way, he did get back to me. Here is what he wrote:


Manny,

Our old dispatch frequency suddenly had an interference problem at Cmed. A new frequency 12.5 KHz. away from ours was put in service at approximately 125 Watts Data burst less than 1/4 Mile away. It broke up our transmissions so bad Cmed could not hear us. Thus the emergency switch to our new frequency until we could get a phone line or other resolution. Our main problem with this frequency is, back then, it was never listed as a control station at CMed. We are in the process of doing that with our new public service frequency. We have to simulcast because our pagers and portables are not programed to the new frequency narrow band. I expect that will happen within the next month or so.

Thank You for the ham class offer but for now I have no time. Maybe later on.

Thank you for your interest.

David Geloso
Acting Chief
Ansonia Rescue And Medical Services

So that's it folks! Now, I am very curious, as most of you probably are, who or what entity is the source of the interference 12.5 Khz. away! Hmm!
Time to do some fox-type hunting......I hope that they get back to some kind of stability soon. People who are in the business of saving lives should not have to worry about communications issues too. They have enough on their plate already. Geez!

You don't use Business channels for Public Safety, that's the first problem. They should have gotten off that channel and the GMRS a long time ago. As a talk around channel it may be OK, but not as a first line frequency.
There is a Passport system at Quinnipiac University right next to them on 461.4625, at 300w erp, but they have been on it since 2001.

Exactly. But with nothing available its hard to do what you need to do.
Off the top of my head I know Orange, Woodbridge, Manchester and Glastonbury all work off Business channels.
Woodbridge is weird as they use a Business channel as primary and a Public safety freq for backup.

As for ansonias noise try 461.4375 for the new Yale Univ LTR system, tactical comm is low bidder and is putting it in, its been on and off for a few weeks. Also i have noticed a state wide LTR system using freqs that they are licenced for in other parts of the state where ever they want

LTR Statewide- could that be Marcus Commmunications? I know he is licensed for quite a few systems in CT.

Doc is pretty good with getting back to people and he is a stand up guy. I've known him for many years. I'm glad they are switching to something that will work better for them as oru town is quite interesting when it comes to operating a radio system in a river valley.

As for the business frequencies, you all have to remember that the allocations changed for many bands and so now you have public saftey mixed in with business frequencies because of the at change, especially in the UHF spectrum. This was the case when ARMS moved from 462.675 (as this was assigned to them back in the 1960's / 1970s before GMRS was allocated to this frequency) to 461.450.

Hopefully they can solve some of the previous problems thier radio system had suffered from with the new change.

Ansonia Rescue Medical Services is now operating fully on 460.4250 DPL of 343. The link to 461.4500 has been taken down. Sounds like they have better coverage now in the city.
