From the CGC COmmunicator:
I thought this would be of interest to everyone here. Note that 839 MHz is right in the middle of the CDMA cellular bands. Nevertheless, it is very important that you use good engineering practices with your wireless equipment, and ensure that you're not interfering with licensed users! Remember that everyone here is unlicensed, and could theoretically get a letter just like this (though the chances are fairly remote if you're not interfering with anyone).
Notice of Unlicensed Operation issued to an individual in Montebello, CA for operating an unlicensed wireless mic on 839 MHz and interfering with a Verizon cell site.
