OT: Wireless Microphone

Why not get a pair of superheterodyne 49MHz walkie talkies, and use one for the transmitter and the other for the receiver? No stability issue, unlike LC tuned FM broadcast band wireless microphones. Since it's voice, no problem with the narrow deviation.

Obviously, you can buy crystal controlled wireless mics, but I assume they are considerably more than buying a pair of these walkie talkies at Radio Shack (assuming they are still being sold, FRS seems to have taken the limelight) or a garage sale. I've certainly been tempted to give them a trying in this application.

Radio Shack used to sell a wireless microphone pretty cheaply that would work with any FM radio. A plug from the radio to the mic input would be all you would need then to do what you want.

I have experimented with many schemes and have come to one conclusion:

Rent a decent diversity system (like a Shure) from a music store for the day.

In article , Jim- T@analog_invalid.com mentioned...

Our media Svcs checks out this wireless and portable unit made by Samson.

Don't be afraid to spend a bit on a decent system if you expect it to stay working for more than a few months. BTW make sure it uses space diversity reception with two antennas.

Too much interference from cordless phones.

Several. What is the budget?

It'll be out of my pocket, but say $200.

I remember seeing a couple of 49 and 70 MHz wireless mic solutions when I was in there last. Not sure on the receiver taking batteries as is, but of course an external battery pack is easy.

How about a wind-up generator powered one? Or if you're using the FM broadcast band any big boom box (shoulder carried portable stereo as is common in LA and NYC..) should suffice.

Or renting makes sense here too. Especially if from a shop with decent maintenance personnel.

Diversity is best with 10 wavelengths or more between antennas, which doesn't sound very feasable in this application. Just a couple 1/4 wave whips sticking out of the back of the receiver won't buy you much in the way of protection against dropouts.

Sure, most brands of Camcorders sell them as an option. I'd suggest the RCA, but since it died after less than 10 years of use, I won't.

I used one to record my daughters wedding back around 1992.

Samson make a airline system which is a battery powered receiver and a small snap-on type transmitter which will plug on to any dynamic cable microphone. model AM1AX1

Here's a link to a Radio Shack unit that looks reasonably good. It comes with a mike and receiver. Some years ago I gave one, not as good as this one, to a friend who taught dance lessons. It did a good job.

Any boom-box with a line-out.

You can battery power the boom-box, tune it to Mr. Microphone's FM-band frequency, and link it to the existing mixer.

The one that was xtal controlled wasn't too bad, but it was underpowered. The one that was a clone of Mr. Microphone was just a worthless toy.

If you plug the output of your radio into a mic jack, you must use an attenuator. Usually a 100k and 1k inside the plug will work okay.

----------------(from OED Mini-Dictionary)----------------- PUNCTUATION - Apostrophe Incorrect uses: (i) the apostrophe must not be used with a plural where there is no possessive sense, as in ~tea's are served here~; (ii) there is no such word as ~her's, our's, their's, your's~.

Confusions: it's = it is or it has (not 'belonging to it'); correct uses are ~it's here~ (= it is here); ~it's gone~ (= it has gone); but ~the dog wagged its tail~ (no apostrophe).

I bought some batteries, but they weren't included, so I had to buy them again.

I didn't think about rentals, but this is even better. Rent a setup and if it works out, and you're still interested, buy it. If it doesn't work, you don't have a bundle of money tied up in it.

Renting music equipment is typically pretty affordable. I remember renting an 800W head, two full-range driver cabinets with stands, various instrument stands, mics, etc. for about $45 a day. Of course, this was 10 years ago...
