Niagara Region MPT1327 Trunks

Update to the Niagara Falls Maxtel

They seems to be a lot busier then other ones.. so far I have logged 23 LCN Frequencies, 512, 515, 516, 517, 519, 520, 521, 526, 528, 769, 770, 771, 772, 773, 774, 775, 776, 777, 782, 784, 785, 788, 789 and 14 tg's, 115, 6000, 6001, 6002, 6006, 6007, 6015, 6018, 87921, 292725, 292726, 292727, 292728, 292740. I think i will try to decode the one in Fonthill or Caledonia when I get home tonight and leave it over the weekend.

You know of course that MPT-1327 uses base/offset/step (similarly though not identically
to Moto systems). Have you been able to match these channel numbers with frequencies?
Also, there can be multiple ranges also like Moto, so there may be some discontinuities.

Dave

 

[mbstone99]

I haven't been able to match the LCN to a frequency yet.. From what it looks like there is a multi ranges with how the LCN's jump from the 500 range to 700 range.

Matt

 

[DaveH]

Unforturately Unitrunker does not sure the actually frequency it shows the LCN channel #. I know is you have the right data for the system you can find out what the frequency is by using a calculation. I would be sure as hell interested to see what active frequencies each of these MPT1327's use.

Now according to Unitrunker.. this is the data I have so far for the Maxtel down in Caledonia (control channel is 420.0250).

Base 200475000
Step 125000
LCN's 256, 257, 258, 261

Matt

Matt, just trying to figure these Base and Step numbers. What number does the base represent? Shouldn't it be frequency somewhere around 420MHz? And how does Uni deal
with offsets?

I presently can't use UniTrunker because it doesn't seem to like Win98. Another MPT utility (the German one I think) causes the blue screen.

The TimeMCI system around Ottawa seems to use different base/offsets for different sites, even within the same frequency range (i.e. 451-455 or 460-465).
The stepsize is 6.25kHz, which Tronquito doesn't handle correctly. The first offset may be a small number such as 1.

I am trying to figure it out as in Unitrunker it shows then as some odd numbers.. My scanner at home decided to change to another control channel. But for system ID 20633 the LCN's found are 769, 770, 771, 775, 784, 785, 789..

The base shows up as 200275000 (not sure about this) and the step is 125000 (12.5khz?) and the control channel is 420.9000. I hope that this help.

 

[mbstone99]

I have been still trying to monitoring these MPT systems. System 20657 Caledonia is really weak today which is very odd considering that it the closest one to me. That frequency is also licensed down in Niagara On The Lake (Queenston) so I am not sure where this one is. There isn't a lot of traffic on there so far so I am not sure. Last night System 20649 (Thorold) was listenable here as well as System 20625 (Niagara Falls). Out of the 4 Maxtel systems the one in Thorold and the one in Niagara Falls are the busiest. Thorold so far has almost 20 or so frequencies, Niagara Falls has close to 25 frequencies, compared to just over 10 for the one in Fonthill and about half a dozen for the one in Caledonia.

yes on my scanner, the fire dept radio only displays talk group 1 through 16

Not to revive a dead thread here, but...

The Niagara Falls FD don't have 16 talkgroups. They have:

GRP 1
GRP 2
GRP 3
GRP 4
FUTURE
NFNY
ALL CALL
EMERGNCY
and a simplex chanel.

I'm also curious as to how well Unitrunker works on an MPT system. I'm familiar to a very limited degree as to how an MPT system works but I'd love to change that

I have tried the lastest version of Unitrunker with a MPT system but never did get it to work no matter what I did. The version that was released before that was the one that I was using when I was checking out these MPT system and it did work like a charm. I think that both of these versions are still available on the Wiki pages on RR.

You'll want to program that one in as Niagara Falls FD Simplex.

re fire department

408.3500 PL 131.8

Can you confirm that 408.3500 PL 131.8 is Niagara Falls Ontario Canada, I never new that this frequency belonged to the fire department, I have done several searches and can't find this frequency.
Steve

 

[exkalibur]

No, but I can confirm 408.650 with the same tone! Typo.. I heard xjf300 calling on it the other day. I did a search on tafl and didn't find it anywhere in Canada.

I can confirm that 408.650 is not part of the fire department radio frequencies.
Steve

 

[exkalibur]

Sorry, I beg to differ. I heard them using it the other day.. It wasn't a trunk channel as there was a pl tone.

Thanks Firefgtr, I was just going to send you a private message to see if you could help in this matter with 408.650, Also do you use the old radio's for anything since the fire department went to the new Maxtel Wireless system. I have been monitoring 408.650 Since Last night almost 12 hours and have heard nothing on 408.650.
Steve

 

[exkalibur]

I would imagine you wouldn't hear much. Keep in mind they stay on the trunk system unless them have a reason not to, such as coverage or if the system goes down.

 

[firefgtr]

the only time we use simplex (T/G 16 ) is when we are in a building and we can't radio out also the old radios (150.545 mhz) we sold....but the freq is still used for paging ie. voice pagers (motorola Minitors) and for broadcasting the data burst for the new alfa-numeric pagers...

 

[DaveH]

408.650 sounds like it could be a link frequency, so depending on where you
are, some may hear activity and others may not.
