Milton fire

[mainetrunk]

Past week Ive been getting p25 sounds on miltons fire freq-154.325. So, I set up for a p25 nac search not knowing when they will chat again. Within 2 days I got the nac of 343. I never hear what they say, I always miss it. So now Ive heard it enough to know its close and clear. Now to figure out who it is. Any ideas? Strafford county's former South repeater freq just checked in with a 10-5..nac-860

Milton Fire is licensed for P25 on that frequency. New system perhaps.

Ahhh--where abouts do you see the p25 mention in there? Ive never seen 1? Or Im num

Note the emission designator of 8K10F1E - P25 Phase I C4FM voice (typically used for single-site systems; P25 mode in RRDB)

So, any entity that has 8610f1e is p25--no other numbers-codes? thx

It looks like they modified their license for 8K10F1E P25 emissions on 2/8/2013. This usually indicates a upgrade to P25. Now you are hearing P25 and seeing a NAC. Hmmmm

Well, heres another-151.085-nac--826..I just got it. 11k253E and 20kof3e for emissions licsensed to Barnstead N.H---aka, home of Lakes Region fire...ULS License - Public Safety Pool, Conventional License - WQLB205 - BARNSTEAD, TOWN OF

As licensees complete narrowband conversions, they may also add the P25 standard emission as well. A good part of local PD's use their town channels in P25 now regardless of the license emissions listed.

The best thing to do is monitor the frequency for an extended period and see who's talking. With Barnsteads hit of NAC 826, that definitely warrants additional monitoring to ensure that wasn't a false hit from an NHSP unit.

Milton was also recently licensed a new repeater on 151.415.

I had no clue milton was licensed on that repeater. Do have a tone for it? And I never knew milton went to p25. I thought they were still using their 154.325 frequency with a tone 136.5. But for laughs and giggles, I set to analog search and a tone of 114.8 came up. I had no clue where this tone came from. I figured since I live near the mass. Border, it just be coming from mass.

 

[KB1VLA]

Milton FD is still 154.3250 136.5.
I believe the 151.415 frequency is for the Highway Dept.
154.3250 114.8 is Georgetown FD's new repeater.

 

[BD70]

Ok thanks clearing that up for me.

 

[KB1VLA]

They are dispatching a call right now, using analog 136.5 and P25, NAC 343.

 

[jmarcel66]

Jacob, are they doing the mixed mode in any particular format? Is Dispatch Analog and mobiles P25 or something like that?

 

[BD70]

Hey KB1VLA, are you picking up milton perfectly from where you live? I'm not picking up the NAC code. I live in Salem so that's probably why. I also have another question. From where I live in Salem, I can pick up rochester, concord, the ossippe valley or Carroll fire, wolfeboro, and Portsmouth but I can't pick up any dover activity. Can you explain this to me please?

I wish Police Call was still in publication. They had a great intro section that explained so much; and address questions like this.

Ultimately, it comes down to a few things: Location, Site Transmit Power, Receiver specs, frequency band and a few other minor things.

I live in Concord, closer to Wolfeboro than Salem; but I can't hear them at all. I barely get New London, but I can hear Portsmouth, Rockingham County, Farmington (but not Rochester). I also can't hear Dover.

It ultimately comes down to location and what paths/channels of topography exist between you and the transmitter site. Then transmitter power kicks in. You may hear a 100 watt radio on a hill; but can't hear a 40 watt transmitter on the same hill. The RF band plays a role. VHF will do better than UHF for distance. Then the smaller aspects kick in like your receiver, antenna (inside, outside, rubber ducky, etc), RF interference in your receivers area, etc.

Milton's repeater is on Mt. Tenerife, so it will have a pretty good footprint. Dover's repeater is on a 100' tower at City Hall / Police station, so it won't cover as much area. I'm surprised you can hear Portsmouth, it seems to me that their repeater is low power, signal strength really drops off after I get out of town.

 

[BD70]

I can get Portsmouth but its not that strong. I was also amazed that I could pick it up. From where I live in Salem I can pick up York Maine fire and police. The scanner I'm using is a BCD 996xt.

Carroll dispatch was having radio problems (audio kept dropping out), then both dispatch and the units switched to P25 momentarily, then back to FM.

Rooftop antenna's are wonderful.
