I believe that it's 174-216 MHz, however I just got the Canadian price list this morning and they're not on it yet. I heard from a reliable source that they are waiting on Industry Canada approval.

"For now" being the operative wording here. When we know how many broadcasters have sold their current spectrum, and how many of them will continue to broadcast OTA, we'll know how much of the 500MHz UHF spectrum and how much of the VHF spectrum will become occupied by transmissions currently in the 600MHz band. Everything is on the table here, and any plans made now will be a crapshoot.

That said, it's clear that the wireless mic/IEM/comms manufacturers will all be looking at ways to cram more capability into less spectrum, and that will almost certainly mean products that can operate in VHF. It will probably also mean products that can tune over a wider spectrum per device while still preventing operation in those parts of the spectrum that are unavailable regionally.

I'm glad I am not in a position of having to make short term plans to buy RF products.

Not to thread-hijack, but has anyone heard any word on whether/when something similar is going to happen up here in the Great White North? It seems to me that "for now" might mean a whole lot longer up here than it does south of the 49th...

Canada will have a bit longer to use current products if the 700Mhz deal is any indicator.
How much longer...no way to tell.

That's true...but. I've always maintained that for most Canadian companies that are based in the 200 mile wide x 3000 mile long strip of the country that 80% of the population lives in, as soon as you are doing a gig close to the border (say an outdoor festival in Niagara Falls, ON) you're going to bump into the US reality anyway, at least as far as DTV and Public Safety goes. Even if you are based further North, say, in Edmonton, AB, as soon as you have a job that brings your gear close to the border, you're going to be affected. So, while it may be legal to continue to own and use equipment in bands that have been re-allocated in the States, it may not be practical.

Ah, the joys of living in the frozen north! I suppose this means that I'm probably more interested in this particular topic than basically anyone else here.

It seems there's been a lot of grant/capital budget money floating around up here (I know of at least a couple dozen channels of Sennheiser G3 beltpacks purchased in the last couple years by various local community/education groups for their own theatrical use) and so when someone asks me what they should buy (or, more commonly, how screwed are they going to be and when) I've been feeling at a bit of a loss for a concrete answer. I guess I'll have to wait and see, just like everyone else.

Thanks!

Actually, I would think that a fixed installation in Edmonton (or Sudbury, or Quebec City, or anywhere a few hundred miles north of the border) would be a GREAT place to be for at least the next ten years, as changes in the US should be very unlikely to have an impact.
