Wireless Frequency Finder Device?
Does a device exist that will scan and display the most used, or least used frequency so I know what frequency to use, or not use. I have the Sennheiser G3 Wireless system and I know it has a scan function but I find it does not work that great.

If there was a device that would show me a graph of the frequencies used, I could pick one not being used. I am guessing this will improve my mic performance. Anything out there? I know one of the Shure Wireless systems has this built in one of there mics receivers and it works great!

Google and other online have databases of which frequencies are reserved for wireless microphone usages in your area. Any area, in fact.
 
The Google service is OK...but it's only GENERAL. You need to know what's happening at all frequencies RIGHT THIS MOMENT and in the EXACT LOCATION you are trying to work in. Right?

That SHURE system that does that - any more info on it? Perhaps we can trace that sort of a device by seeing how Shure is doing it.
 
Hmmm. I see.

Is that just for interference, or can you get a fuller sound by working on the most optimal frequency? I ask because I've been getting great results (relatively speaking) from following the local open channels and going from there. And while I think my results are great given my equipment (Sony UWP D V.2 with stock lav), you make me wonder if I shiuld be even more attentive to the frequencies I use.
 
Yep..... A simple 'RF explorer'.
A lot of location soundo's and OB audio crew carry these as standard kit these days.

There are several models just select the one that suits the RF band/s you are wanting to use.

Forget the online data bases (unless you are doing location planning) but the RF Explorer does it real time at the location your actually at.

In lieu of an actual RF frequency scanner (not cheap), I would recommend the online Sennheiser Frequency Finder and choose a 'vacant' channel or one with the least modulation.. For instance, a channel with a Prx of -80dBm or better. Once on location, check the receivers one at a time for unexpected RF. For multiple systems, use a preset 'bank' where the frequencies should not inter-modulate.
In my experience, the G2/3 receiver's on-board scanner is an inadequate POS.. aka, useless.

BTW Firefox39, a black font on the website's dark BG is nearly imposable to read.

The problem with 'Frequency Finder' data bases is they don't account for 'event' based RF usage. i.e. a beach sporting festival will be full of RF on 'that' day but the day before or after will be completely free of any RF.
Just remember its NOT just 'YOUR' radio mics that are using the spectrum.
