Forgive the basic questions. I run sound for a group (actors and musicians) that has several older Audio-Technica wireless mics - a combination of System 8, System 10, and 200 Series. I'd like to replace them with some rack-mountable units, but the FCC auction has me leery and I'm fuzzy on a few issues. I did some Googling but couldn't find the info I was looking for. Here goes...

1. Which wireless spectrums are free and clear to use for the foreseeable future?
2. While I know that no-one can predict the future, what are the chances that further frequencies will be auctioned by the FCC? Or, in other words, are there certain frequencies which are legal to operate in now that I should avoid?
3. Is there a tool, besides Shure's wireless workbench, which allows someone to "see" what wireless frequencies are in use/should be avoided for any given venue? I'm specifically interested in something that's *relatively* simple to operate.

Many thanks --

Hey Mike, welcome to the forum. For starters, the answer to many of those questions depend on where you're located. Armed with that info, we can make some *somewhat* more helpful suggestions.

No problem - I live in Dubuque, Iowa (zip: 52001). The group tours in the east part of the state. Thank you!

Welcome Mike.  This is going to be an interesting topic.  Are you asking as a pre-purchase question?  I know of nothing that alleviates at least a simple scan during setup.

1:  700MHz equipment has been illegal for years now.  600MHz has been sold and testing roll-out has begun in some markets (see other posts on this forum for more info).  Below 500 is fine for the foreseeable future.  There's 2.4Ghz equipment but I'd stay away from that due to WiFi interference and all the other consumer stuff that runs in that band.  Shure has some 900Mhz as well as VHF (100's-200's) range equipment as well.  I'm not as familiar with the rest of the offerings out there but I'd expect the other big name players will have similar offerings (though I'm not sure about the VHF stuff).

2:  The 600MHz auction wasn't as big a success as some expected it would be.  This may make future auctions less likely but you never know.  In 10 years we could be going around on this again.

3:  The only way WWB really lets you "see" the spectrum around you is by using a compatible receiver (one with network connectivity these days) to do a scan of it's frequency range.  You can also import properly formatted scans from other RF scanners into it.  I believe Sennheiser has software with similar functionality.  IAS is another top end pro product used for coordination.

How many channels do you need?  Any need or desire for IEM systems as well?  You're in a low population area so that will make coordinating a lot easier on you.  You really do need to plan to coordinate at each location for best results.  You'll get best results with a software product that will do the intermod calculations for you instead of relying on scans by each receiver.  If you're using something like WWB it can scan, calculate, and deploy.  Then all you have to do is just sync your transmitters and you're ready to go.

Don't forget about antenna combiners and proper antennas.

I would give Shure ULX-D a long look. Without looking up the various 600 MHz re-pack charts, which can be found here:http://forums.prosoundweb.com/index.php/topic,164023.0.html (that means that some DTV channels that are currently above Channel 37 will be moved to a new channel below 37 or in the VHF band), I would venture a guess that in Iowa you are going to still have quite a bit of open spectrum. ULXD systems in H50 or G50 bands should be good for years to come and you can still keep the high density mode in your back pocket if things get tight, down the road. One of the guys on here, Ray Aberele, I think is a Shure dealer who I think covers your territory.

Fwiw, I am going to buy into the ULX-D myself. It's a great system and should be somewhat free from interference for quite a while.

I'm in the process of moving our UHF-R J5 stuff to ULX-D G50.
Seems to be the best option and we tour throughout the USA. I'll get a different band split locally for Miami, etc where there is not going to be much spectrum to be had for mics.

Scott, yes, I'm in the process of getting quotes for new wireless to replace what we have - mainly because I want units that are rack mountable, have locking transmitters, and so on. It's nothing complex - just two wireless handhelds and one earset mic. But we've had problems with interference using our AT mics that live in the 169-170 MHz range in the past. Can you elaborate on the scanning process? I'm aware of Shure Wireless Workbench, but I don't own it and have never used it. I'm not opposed to paying for it, but I'm wondering if it's overkill for my application.

Thanks Erik! We're not looking at many channels - just three. We're not using IEMs, but that is a possibility in the future. Since I've been using Shure for years, it sounds like WWB may be the best solution.
