Which Sennheiser 100 wireless freq. set best for L.A. use?

[Stas]

I'm planning to buy a Sennheiser Evolution 100 wireless system for use primarily in L.A., Ca. After checking out the chart of local tv frequencies on the Lectrosonics page, it seems that the "A" version of the kit, (518-550 mhz), is the one to get, rather than the b (630-662) or C (740-772), because the A range has the least amount of channels in use in L.A.

Can anyone using the Senn 100 wireless in L.A. confirm this? Do I want the A, B, or C set?

Thanks for any info.

You should use A

DATABASES OF USED RF SPECTRUM
Enter your location in USA and Freq or TV channel and other Tx (TV radio, etc.) nearby will be shown in full glory including pretty site maps. Pretty interesting!
http://www.globalcommnet.com/%21station.html

Another USA list of digital TV and when they are supposed to come on line: http://www.fcc.gov/oet/dtv/start/dtv2-69.txt (hard to search)

One of the FCC databases to find TV stations by call letter or location: http://www.fcc.gov/mmb/vsd/tvq.html

Canadian digital frequencies: http://www.locationsound.bc.ca/dtv.htm
Use this link to the Audio Technica site, select any UHF/VHF product and enter your ZIP code. http://www.audio-technica.com/cgi-bin/tvfreqcheck/tvfreqcheck.cgi (may be incomplete).

When traveling in the USA this site lists all stations and their web sites. It doesn't list actual frequencies but it shows their geographical location on a map. Good search engines: http://100kwatts.tmi.net/
also: http://www.100000watts.com and check http://100kwatts.tmi.net/tv/LAX.html for all stations in LA.

Lectrosonics has put together a nifty television station look up database on their web site that shows stations and corresponding Lectrosonics Radio mike block numbers for the US. http://lectrosonics.com/cgi-bin/tv_form.pl
Sennheiser has a easy to use frequency list on the web:

Also Lectrosonics dealers have a good proprietary database to find empty spectrum for any USA city. Very useful in 2001 with new TV stations daily.

There is a document that explains many of the problems with interference that is a must read for any audio person in this millennium: http://www.lectrosonics.com/wg/wgint.pdf

FCC commissioners ask: How come there are 500 TV stations and there still is nothing on?
The congress answered in 2004 that more than 3 owners of all media is a democratic necessity.

Mayhew & Company at 818-840-9293 has a pretty much up to date database on used USA frequencies. So does LSC talk to Ed Sumner 8181 980-9891

In Australia check: www.soundequip.com.au then to Links / General, check Australian TV Stations by Area and Australian TV Stations by Frequency.

In Europe check http://www.ero.dk/ a huge and confusing site
Loads of all kinds of freq spectrum data: http://tvtower.com/Commercial%20Television%20Frequencies.html

Use this page to check for interference between and among multiple wireless frequencies operating simultaneously. Up to 30 frequencies may be tested together. I am not sure that this site really works as it should – maybe it has been fixed since I saw it last http://www.audio-technica.com/using/wireless/compat/

and loads of Tv and freq. Info a very complete geeky site: http://tvtower.com/Commercial%20Television%20Frequencies.html
