I confirm that line 1 is almost complete and the Blue line is completely finished. I work on the Orange and I saw the TETRA repeaters. I'm going to listen to my 436HP tonight. Guys are going to be at my station tonight

Hello,

I checked the June update of the TAFL and noted some more sites reported on-air in March.

Changed Blue Line
I either had a typo or the frequencies changed
862.1375R 863.6875R LA Pair 2 2S36_SBR104 (Snowdon, 5111 chemin Queen-Mary)

Additional Blue Line
864.0125R 865.0625R LA Pair 4 2S72_SBR95 (Jean-Talon, 430 rue Jean-Talon)

Hopefully I can visit in a couple of months and do some decoding.

After having some fun in SDR#, I stumbled upon 860.0625 & 860.8625 MHz which are listed in the old STM EDACS system but now to be TETRA channels (most probably Control Channels).

It would make sense that there are 2 sites to the new system as there are already 2 sites to the current EDACS system...

For anyone interested, here is what I was able to decode:

Hello,

Most of the sites on this system are underground. The system may still be in build out. Not much activity the last time I monitored the site a few months ago. I have not tried listening below ground yet. I only get up to Montreal one or two times a year.

Yeah, the system is under development but I know someone who had the chance to see some voice activity on the system.

Perhaps, maybe delete the old EDACS system (the one containing the frequencies listed above) and replace it with a TETRA system as there seem to be more activity on it...

I have merged the old thread with the new one from Nov. 11th.

There is so much historical information that is useful and paints the whole picture for reference.

I will create a STM - PowerTrunk system.
