[QUOTE=DaveH;1899899]Besides tone/voice paging on 154.130, there is grinding digital
noise which is not P25. As for other frequencies, someone can check
TAFL under "Morrisburg" etc.

I wonder if there is a CTCSS/DCS tone on 154.1300 for the voice paging, if there is you could at least listen to the analog pages and not have to endure the TRBO noise. This is how Brant county did it, paging in the clear with PL tone and then digital voice from the trucks once they hit the road.

I know the lads at the FD I spoke to claimed they knew it was P25.
I was told originally that L&G was going to be P25 but who knows. Things can change pretty fast. You folks realize that this trbo noise your listening to is in Dundas county.... Right? I'm gonna go out on a limb here and say is it possible that Dundas is gonna have a different radio system than L&G..... lol.
I'm on duty this weekend maybe there will be some brass around with the skinny.... But I doubt it, its
superbowl Sunday.

It is coming in clear as a bell here in Morewood, but I am 40' up. I also get the new Millar's Corners Fleetnet site loud and clear. Good questions.

All the jitter stuff in there is a sure sign of bad performance by the tap...

OK Cool. I will try the other tapped scanner and see how it works. I get perfect decode (99.6%) with T88 on the Millar's Corners Fleetnet site with that scanner but for this I had to open squelch and sit on it vs the old 2037 opens squelch and is nice and clear every data burst. I have a 2050 tapped to try.

The two level data used by Fleetnet is much easier to decode than 4 level data (used by TRBO, P25 9600 Baud trunking etc). Depending on how your tap is setup, you may need to refine it a little to dial it in.

So maybe a different resistor or something?

You need a voltage divider... basically 2 resistors and a capacitor. I had a drawing of it here somewhere... just trying to find it.

Edit: Found it. It's crude but hopefully gets the point across. Don't forget to ground the jack as well (I didn't show that on the sketch).

Cool, have to do some poking around. Tried the tapped 2050 and it was about the same with DMR and worse on Fleetnet. Never tried it before just noticed the tap plug on the back when I bought it. Tap is good for Fleetnet sites that are closer but not for Millar's Corners.

I have DSD running here on Provoice, so I switched the parameters for mototrbo.
All I am seeing is a trbo data burst saying "slot idle" on that frequency.
I also tried 450 and there is a load of mototrbo signals there with voice, I was surprised!
Things are sure changing fast.

Is it possible to hear the mototrbo on a trunking scanner if all of the radio traffic goes through a repeater of a certain frequency?

No.... MotoTRBO is MotoTRBO.... There aren't any scanners out there that will touch it.

Offside perhaps, though it does tie into the nearby S. Dundas migration to
TRBO and how to listen; but have heard no definite reports on that, such as
if it's encrypted.

Your question could best be answered by anyone in the coverage area who
is monitoring the licensed frequencies 164.235 and 166.965. If anything's happening,
even preliminary testing, it would heard there. If you have a P25 scanner and hear
something (hopefully clear), that's useful; even someone with non-P25 radio who
can recognize what P25 "sounds" like can provide a useful tip-off.

I was talking to our equipment guy at training and he showed a pamphlet for the new pagers. The original model quoted was a http://www.swissphone.ca/docs/DE920-Product-Sheet.pdf but nothings been finalized and they may upgrade to a model with a built in voice synthesizer. Nothing on the radios yet and I haven't heard of any testing.

Would be nice to get a radio spec I think that woukd shed some more light on the direction they are going in

Has anyone monitored the new licensed frequencies?

I see Enbridge Pipeline made a donation to them towards their upgrade... Kudos to them! They have made sizable donations to the department that I belong to over the past few years (including funds for a slick new thermal imaging camera a few years back)... nice to see a company actually giving back to organizations that can use it.

Holy crap... 19 XTS2500's at $4100 a pop. Can certainly see why TRBO is an attractive alternative, even if it isn't technically for public safety use.

Hopefully P25 which is designed and meant for public safety and not TRBO which is for business industrial use which has unfortunately made its way into some public safety systems
