Sudbury Hydro DMR comms: now you hear them/now you don't. Thoughts?

[sudsyjkh]

Hey all, hope things are good.Coming at you with a bit of a strange one today.

I've been monitoring the Sudbury Hydro DMR frequency (170.175, CC-1) for over a year and literally haven't heard a single peep in all that time....Until yesterday...Flipped on the radio and along with all the normal city and public safety comms I'm used to receiving, was hearing both truck/control room sides of the convo without issue. Sounded like one crew working on a pole replacement and another doing equipment upgrades on a couple switches, naturally with lots of steps and sequences.

Now fastforward to today. It seems like they've gone completely silent again.
Just wondering what would cause this to happen? Is there anything I can do in order to keep receiving them in the future? To be fair, I"ve never had the best luck with single-freq DMR stuff.

Thanks in advance folks.

Since you don't list a TG being used I can only guess and my first guess is backup or special event TG seldomly used, run across that from time to time.
