Do you have a digital trunk tracking scanner?

They are on here:

https://www.radioreference.com/apps/db/?sid=7924

If so, use the site closest to where you live and monitor these talkgroups:

Code:
41801	a349	D	HRM Transit1	Halifax Transit ops 1 	Transportation 
41802	a34a	D	HRM Transit2	Halifax Transit ops 2 	Transportation 
41804	a34c	D	HRMTrns Proj	Halifax Transit projects 	Transportation 
41806	a34e	D	HRM Trns Mnt	Halifax Transit fleet maintenance 	Transportation 
41807	a34f	D	HRM FerryOps	Halifax Transit ferry operations 	Transportation

I have an Sdr Play Rsp 1 and have it hooked up to HDSDR and DSD+,i have been able to decode p25 and DMR quite well but not able to use talkgroups which is why i was wondering about the frequencies.

Thank you very much for checking into that info for me.

I wish i could get unitrunker working with the sdrplay.

I really need a digital trunk tracking scanner but they seem quite expensive at the moment.

It depends on what you want to listen to. The 'administrative' type stuff (Transit Inspectors, Ferry Operations, etc) are on the trunk system (TMR2) as MCIUPA has indicated.

However, if you want to listen to the dispatch centre and the actual buses. Comms are simplex. Halifax Transit uses 8-bay dipoles at their two facilities (200 Ilsley, Ragged Lake) to communicate effectively with the buses. they are in the 410-415 range listed at: https://www.radioreference.com/apps/db/?ctid=4698

One of the listed repeater pairs is for Access-a Bus operations.

Mode is FM ....SDR decoding of any type not required.

Seems to me there are more simplex channels than what is listed...some searching would turn them up fairly quickly, especially if you are near downtown.

Note that the base units talk on one frequency and receive from the buses on another. Similar to what Taxi outfits were doing very widespread at one time. Buses do not hear each other... ("half-duplex" is the term for this type of operation)

There are at least two channel pairs that function that way, but as I mentioned I think there is a third channel pair there too.

According to Marscan's old site there's 4 half-duplex pairs for coms between BTC and the busses (3 main pairs and a fallback pair) as well as the access-a-bus repeater.

Base transmitter Mobile transmitter Usage
411.0375 416.0375 "Fallback Channel"
410.1125 415.1125 Channel A
413.9875 418.9875 Channel B
412.8875 417.8875 Channel C
410.1625 (rptr output) 415.1625 (mobile and control) Access-a-Bus

Take a look at the following page, gives a good idea of how the system is (was?) setup. Not sure if this info is from before of after the switch to the new TransitMaster AVL system though.

They still use the VHF for comms, but I'd bet they are using the MDTs on their new Trapeze system for a lot of routine messages...

Thanks for the info guys.

Now that i am back to scanning albeit with a non trunking analog scanner the BC125AT it seems there is still enough out there to keep me interested.

I live close to Shearwater and picked up a fair bit of traffic today regarding Helicopters.
I can also receive a fair bit of traffic on its way in/out of YHZ and the high level stuff.

I want to explore the Mid-Air Refuelling over Nova Scotia as well.

I occasionally use my SDRPlay Rsp to decode some digital transmissions but its painful when it cannot do the trunking stuff properly.

Hopefully the Digital trunking scanners will come down in price a bit one day and i will purchase one of those.
