i am getting alot of traffic here in mansfield on 453.9125 and i know it's fire activity, but i can't find it in the database, is it an image freq of some kind of fire freq?
453.9125?

as of right now i am getting on this channel that to Contact EPS on ICALL?...and it was also stated that trooper 1 is taking off from the airport....now it is saying calling car 3 to TM?
UPDATE***
i am not sure if this is some kind of operations CMED?....but i have Vernon and Manchester medics coming on here and also mansfield fire rescue?....they also called for a unit to move to ITAC 3 to communicate with trooper 1...
it also sounds like i might be picking up something from rhode island, they are calling for a chain saw, and iding as service 172 and rescue 145?...and the dispatch is id'd as command

453.9125 is a statewide low power channel (2 watt ) licensed to the state of Connecticut, Dept of Transportation. You might be hearing something from Bradley Airport as that is one of the control points, although that may be unlikely because of the power level.

that is the same thing i heard, i was listening to it on 453.9125, and i keep hearing manchester ambulance and medics being dispatched off this frequency, he said it is low power, but i think it might be an interop channel or an X Patch, i dont know, but i will keep listening and tell you guys all about it, i heard that whole brush fire today, it seemed pretty huge, they had alot of companies down there, i dont know where it was, but it was some cool stuff, i changed over to the Icall channel and i didn't get anything after 10 minutes,
i think they turned over to icall to talk to trooper 1, they had it up to monitor the fire,

That would be TN, not TM. TN is the Tolland County 911 Dispatch Center's callname.

I heard a bunch of traffic relating to this incident on the Somers 33.44 repeater (452.225).
Unfortunately, I did not have 453.9125 programmed in.
Service 172 is a service unit out of Union CT, and Rescue 145 is a rescue truck from Staffordville.
I believe the fire was in Union. I was in Somers during the day, but was only listening to the 33.44 repeater. I haven't seen anything on the news sites about it, though.
According to the DEP:
The Forest Fire Danger Level for Sunday, April 30, 2006 is VERY HIGH

As of right now this frequency is a cross band repeater and link frequency for the Mansfield tower site primarily for 33.44. It is licensed by TN as a low power mobile frequency. The state uses this frequency without a PL for lower power data transmissions and has been receiving TN radio traffic. TN is working to replace this link frequency with a new one as and FX1 and FB2. I will keep everyone updated as changes occur.
As for the fire this weekend, Union Fire department had a 10 to 15 acre brush fire. They utilized Trooper 1 for recon but I am not sure if the dropped any water. They utilized ITAC 3 off the union tower. I was able to receive all their transmission on my MTX portable in Coventry loud and clear. Once the county support services vehicle arrived on site Service 119 (This has dive equipment, accountabiliy system and UHF and ITAC radios) they also started to utilize Fire Ground Red for operational fire ground channel. (458.4125 which is also QV's UHF Channel 6)
The fire also activated the newly formed Tolland County Wildland Firefighting crew. Fire 1 call sign is Ashford fire deputy chief Car 120. He was the one that helped get the wildland team together along with others.
Car 3 was a Holland Mass. officer who's department was called in to cover Union's fire station while they were fully committed at the fire. Holland fire helped set up a landing zone at the state DOT garage in union for aquiring personel and setting up their bucket.
HQ-2 and HQ-32 are two of our county coordinator which were activated as support personnel during large county incidents like large brush fires, water emergencies when the dive team is called out and other incidents like the Amonia leak in Ellington a few years ago when the county Tactical groups were activated. I believe HQ-2 actually took over for Command so Car 72 Union's chief could take on more role as an operations officer for fighting the fire. (I am only assuming this since I could not hear the fire ground.

i hear some cool stuff on this freq, i listen to the manchester medics on it, i heard that whole brush fire in action, it was like being there, so it was pretty cool,

TOLLAND COUNTY FIRE MUTUAL AID FIRE SERVICE Call Sign WNHV903 453.9125 and 458.9125 2 watt mobile license.
Also the PL for the Mansfield tower is 151.4.
There are several cross band repeaters throughout eastern Connecticut which use this type of repeater and UHF linking.

Thanks for the update. We will have to see what updates come up
on the database as i dont see them. Also, East Hartford has a license there as of
12/29/2005.

Other Link to listen for
453.6125 is Pumpkin Hill in Ashford. It's a cable tower. Used by QV,
TN and KX. From what I remember it has a scanning
receiver or can be locked on a single channel. Never understood why KX
would use it. and I don't think QV does. Guess it's mostly TN.
Heard 33.44 linked through it all the way to Montville one day.
Another good fire link 33.44 > 155.820 Located at Stafford High School

453.6125/458.6125 is used as a link frequency to control many sites. They are as follows:
Birch Mountain 33.80 toning and 33.90 two way. They use multiple PL tones for this.
Coventry 33.80 and 33.90 but 90 is now disabled due to some problems with interference.
Bolton Fire Station 33.80 for better tone and voice coverage in the town.
Gates Hill 33.80 in Lebanon- TN and KX use this site as a backup. WW has a wire link to the radio but can also use the UHF link as a backup.
QV can also access Gates Hill and Coventry as a backup as needed.
The only active cross band transmitting on 453.6125 is the Birch mountain 33.90 radio on PL 151.4.
Using one UHF pair for RF linking has become a problem especially since it is used for tone and voice on 33.80 and two way comms on 33.90. We are working on solutions for this problem.
Also I beleive Pumkin Hill is 460.5375 although it may have been changed. I do not access this site very often. This radio is a cross band repeater with a multichannel lowband radio that is in scan. It has 33.44, 33.78, 33.90 and 33.80 which all use different input PL tones and one single output PL of 151.4.
Hopes this helps. I will investigate the frequency for the Pumkin Hill site and get back.

Actually the North School road tower in North Coventry was built in 1986. In 1996 the tower was moved to the now Coventry site located behind the town hall. It was literally taken down and rebuilt due to extensive litigation by one town person. The 80/90 6125 radio was moved to the Coventry site until in 2003. When Hebron was having coverage problems KX built a brand new radio on the town of Glastonbury Birch Mountain site that was exactly like the Coventry Radio. They left the radio at Coventry and only took the 453.6125 transmit frequency for the 33.90 portion of the cross band. KX offered the radio to the Coventry fire department and they accepted it. They were not able to find a suitable frequency to ever reactivate the UHF side of the cross band. Attempts were made to obtain a new frequency and recently they actually had come up with one. They were all set to implment the changes when an interference issue came up.
Let me explain the interfrence issue on 6125. The radio at the Coventry tower site and the Birch Mountain site both use 453.6125 as an input frequency with a different PL from the KX birch montain site. Becuase KX uses this to control both the 33.80 and 33.90 radio at Birch Mountain with differnt PL what was happening is that when TN was putting tones out on Covnetry 80 on 6125 and KX keyed up their transmitter at Buckley Hill on 6125 for 33.90 the signal was stronger than TN's and it disrupted TN's tones. This was not acceptable since this is a primary toning site for Coventry, Columbia and Mansfield and is only a backup for QV, KX and WW. Currently the 90 portion of the 80/90 lowband is shut off at the Coventry site with only 33.80 operational and there is a directional yagi directed toward TN. This is only a temporary fix as it prevents the other dispatch centers from effectively backing up TN. Our long term fix is to obtain a completely new link frequency which we would use to control not only the Coventry 80 radio but the 80 link to Gates Hill and Bolton fire station both of which currently use 6125. We would then revert back to the omni directional antenna at Coventry to allow the other dispatch centers to use the site effectively. We are also looking for new link frequencies for Mansfield cross band, Pumpkin Hill cross band, Coventry 33.44 and 33.78 cross band. Long term we are looking at Microwave links to eliminate these highly inefficent UHF RF links. Again as things change I will keep everyone updated.
Also Pumkin Hill is 460.5375 not 460.5625.

Microwave in my opinion is the only way to go.
Why doesnt TN run some copper to the 80 transmitter? These UHF link are a ridiculous waste of bandwidth and most are not even licensed properly anyway. Now if we could only build a reliable simulcast dispatching network....
By the way I know Hebron got a new UHF pair 2875 but it look as though they only were able to license it at their Co.1

You are right from a technical point of view Microwave is the best option but it is expensive to purchase and install as well as maintain.
You are also correct that UHF RF links are a very ineffecient use of RF.
Copper to all the 33.80 transmitters would also be expensive. Once you go outside your exchange the cost goes up quite a bit. I recently looked at a 3 site voting receiver and the quotes I got from SBC/AT&T. The one site out of my exchange was more than the two sites in my exchange combined. Yikes!!
I believe the next logical step for all of the regional dispatch centers would be an analog UHF simulcast system. Pretty much everyone has analog UHF cabability or is getting there. The problem with simulcast is you need to have a good backbone in place and then purchase all the same radios at the same time. Not to mention the GPS clocks and iridium standards. This type of system is a big up front cost and I do not see anyone putting up that amount of cash anytime soon.
