I ran across this elsewhere and thought it might be on interest here.

That's a great initiative, thanks for sharing.

Hell of an idea! It'd be even better if the designated channel was the same everywhere. Giving channel 36 over to devices that max out at 250 mW might give the radio astronomy folks a little extra wiggle room, too...

Good idea! Might be a bit of a squeeze for all of Broadway to be in the same 6 meg space :o
I hope these companies are reaching out the the CRTC as well.
Ike, do you have any contact with CRTC?

Is that a problem in the 416? It sure isn't out here...

There are logistical reasons that keeping the same band open everywhere doesn't make the most sense.  In areas of overlap, TV broadcasts in neighboring areas can't be on the same frequencies due to the overlap coverage areas.  Leaving one fully open would mean less TV broadcast options.

As long as at least some space is kept clear, wireless mic designers can either do like they are doing now and build mics in several frequency bands, or with today's technology, they could build equipment that is more frequency agile that could operate in multiple bands.  While that might make for a little more expensive of a mic, groups that tour the nation would be better off with it.  Those that don't travel could spend less money and pic the mic that works best in their usage area.

That bird has already flown to the ship that sailed after the train left the station. Post 600 MHz re-pack, the spectrum that we have left in UHF is 470-608 (plus the guard band and duplex gap) and newly built wireless equipment such as Shure Axient Digital, Lectrosonics D2 and Duet, Sennheiser 6000 and RAD intercom already tune over that entire 138 MHz band.
Reserving an open DTV channel in each market would still have to fit into the remaining TV channels 14-36. We are not going to get anything BACK from the 600 MHz auction from this initiative.

And in some US markets, generally those urban areas with T-Band LMR, there is no open channel to be reserved.

No, no, no.

What we need to do is just give all this spectrum up. Some silicon boys can play around with it and do all kinds of weird and cool stuff.

We as audio professionals need to petition for more use of WIRED microphones. The 'P' in Pro stands for 'Plug'. As in, "Plug the thing in and do the show". 

Anything else is just setting ourselves (and our customers) up for more disappointment. 

Can I get an amen??

I preach all the time that "if it doesn't need to be wireless, then don't make it a wireless" and perhaps a few listen. The reality is that this ship has sailed, and the days of Roger Daltrey twirling his duct-taped '58 on the end of a cable are mostly over. There are artists who do stick to a wired mic (Dave Grohl, KD Lang come to mind) but it is not lost on staging designers that "Live entertainment" means movement, dancing, clean stages, and no wires.

*We* all know what you mean, and sure, *we'd* all like to see more wires and less wireless, but *we're* not usually the ones who make that call. When we can, we do. Wireless can solve problems, too, but you're right - the ever shrinking spectrum makes us all have to think twice.

In theory, theory and practice should be the same. In practice, they are not.
