• Find the best mic frequency for your area

    I have found what seems to be the easiest to use frequency finder yet.
    http://www.showmywhitespace.com

    Type in the addresses for the places you play at most frequently and note the channels that show green check marks for those locations. Then find a wireless mic with a tuning range that covers those channels.

    A few caveats:

    * The site isn't perfect. It doesn't consider TV signal attenuation from terrain or buildings. In other words, it may indicate that you cannot use certain frequencies in a particular location when in actuality, you can. Better safe than sorry though.

    * The data isn't perfectly current. New transmitters can pop up and create interference on frequencies that the site reports as clear.

    If you need to convert the TV channels to actual frequencies in MHz, choose the "View Full Map" button and you will see frequencies on the left side

      This Just in from NAME:

      NAME Members,

      NAME has partnered with the FCC's Office of Intergovernmental Affairs to bring members the latest in the developments concerning wireless microphones that operate on frequencies in the 700 MHz band (which includes any frequencies between 698 MHz and 806 MHz).

      The FCC has passed a decision that will affect All wireless microphones that broadcast in the 700 MHz band. Microphones that Broadcast in this frequency band must cease operating no later than June 12, 2010. The FCC seeks to prevent unlawful interference with public safety entities and commercial users that operate on the 700 MHz band following completion of the Digital Television transition last June. In addition we hope to prevent NAME members from receiving interference while using microphones,

      If a microphone does not operate on frequencies within the 700 MHz band, no action is required.

      Wireless microphones currently operate in a variety of different frequency bands, including many frequencies outside of the 700 MHz band.

      Only those wireless microphones using the 700 MHz band must cease operating. Some wireless microphones that operate in the 700 MHz band can be successfully retuned to operate in frequencies other than 700 MHz. If the wireless microphone operates only in the 700 MHz frequency band, it will need to be replaced.


      Why did the FCC make this rule?

      Certain wireless microphones have operated in frequencies that are needed for public safety. When these microphones were first designed, the frequencies they used were in between the frequencies that television stations used to broadcast television programs. With the completion of the digital television (DTV) transition on June 12, 2009, television stations no longer use the frequencies between 698 and 806 MHz (the 700 MHz Band) for broadcast. These frequencies are now being used by public safety entities (such as police, fire and emergency services) and by commercial providers of wireless services (such as wireless broadband services).

      The wireless microphones that had been operating in the old TV broadcast channels can cause harmful interference to these public safety and wireless consumer services. Therefore, all users of wireless microphones (or certain low power auxiliary stations) that operate on any of the frequencies in the 700 MHz Band - including both licensed users (under Part 74) and unlicensed users - have to stop operating in this band.

      The FCC is only prohibiting the use of wireless microphones that operate in the 700 MHz Band. You may continue to use wireless microphones that operate on other broadcast frequencies. Microphones with cords are not affected by the FCC's decision.
      What Happens If Someone Does Not Stop Using a 700 MHz Band Wireless Microphone?

      Using the 700 MHz Band for a wireless microphone after June 12, 2010 could be extremely dangerous and could even be life threatening. Police and fire departments, and other public safety groups, use frequencies in the 700 MHz Band. Interference from wireless microphones can affect the ability of public safety groups to receive information over the air and respond to emergencies. Harmful interference to these communications could put you or public safety personnel in grave danger. In addition, use of your microphone can cause unlawful interference to consumer services provided using the 700 MHz Band. Failure to comply with this FCC requirement may lead to civil and/or criminal penalties. This will be determined by the FCC and law enforcement on a case by case basis.

      Good stuff, Sawdust, thanks. I downloaded the iPhone app for this.

      The iPhone app will be more helpful, even thought it's not that great. The website is horrible. It is very slow which makes it almost unusable.

      I called ElectroVoice after having issues w/my wireless mic and they said I could call them any time with the address of my gig and they'd tell me what channel to put the receiver on. It has helped tremendously!

    He bought a Dell touch screen PC today from Micro Center for $425 plus tax. I'm in his apartment now with him using VDJ. He's getting used to it. It's hard for me to get use to. I got big hands. For now I'll stick with my 6000 controller. I got that down pack. It's great though. All he has...
