Bye bye 700 MHz

So...with the supposed deadline for wireless operations in the 700 MHz band (698-806MHz actually), what are those of you with equipment in that band planning on doing? Tossing it? Using it anyway? Manufacturer upgrade programs?

If nothing has changed, I believe the proposed date fro the deadline was February 17th, 2010, but I don't know if that held or not...

That's a tough one. Fortunately, all of my Shure and one of my Audio Technica systems are outside that range. One AT and one Azden system are in. Curiously, Azden's advice to me was to listen for active users and if there aren't any, just go ahead. I'm not sure that's really good advice. I feel sorry for the facility I used to manage, with dozens of Shure UC systems that all fall in that range, directly across the river from Manhattan, and they have to replace everything.

"All users of 700 MHz Band wireless microphones (and similar devices) who wish to continue to use their equipment – including users such as theaters, churches, schools, conference centers, theme parks, and musicians – will need to retune (or replace, if necessary) their equipment no later than June 12, 2010...."

"... If information on the device indicates that it operates on frequencies between 698 and 806 MHz then the device uses the 700 MHz Band and may NOT be used after June 12, 2010...."

I still use some old VHF mics at 202.5 and 193.7 mhz which fit in guard spaces for the local TV stations. I always feel better doing fishing docos and other risky jobs with old mics.

The difference between Knowledge and Wisdom is... Knowledge is the knowing of facts.... Wisdom is the sensible application of good quality knowledge...

Good point about the VHF units. I also still have a couple of Shure VHF units in service, along with my more modern frequency agile UHF systems, and those old units have never failed me in any rf environment.

Don't panic. The 700 frequencies will be good for you for a long time. Here's what Lectrosonics has to say about it: http://www.lectrosonics.com/PressReleases/whitespace/whitespace.htm.

Basically, although that spectrum has been taken from us, no one is rushing in with devices that will overpower your system. Lectrosonics will change your system's block for about $275/unit if you're really worried.

OS 10.4.11 /
Mac Pro 2x2.66 Ghz Dual Core/ 2G RAM

It sounds as is at least some variety of Lectrosonics units that are frequency agile have some frequencies outside the range in question.

I question the corporate liability of them assuring their users that it will be OK due to that fact that many users will be "going pirate" for a period of time (no matter that it is probably quite true).

I buy things on eBay from time to time and have noticed the increase in wireless mic sets/components with frequencies in this range, or with no frequencies specified.

"Buyer beware" indeed.

The fate of the 700 MHz band has been known for a decade. The FCC did nothing to discourage the sales and use of of thousands (10s of thousands?) of units. Indeed, they act as if they didn't know what was going on. "'I'm shocked, shocked to find that gambling is going on in here!" The FCC has become just another politicized government bureaucracy.

Probably way less than 5% of all wireless mics were ever "licensed", so most users are "going pirate". Note that the users who WERE licensed have no benefits to show for it. They must jump out of the 700MHz pool just like us pirates. Arrrg! :-)

[Richard Crowley] "The fate of the 700 MHz band has been known for a decade."

I guess that would be right as the "DTV transition" has been only slightly faster than continental drift.

I guess I was curious to see what manufacturers were doing to offer their customers an avenue to comply...

I've been surprised by how many VHF units I still see in service. I suppose the longer range still has it's applications.
