I am looking for a portable/handheld scanner that will lawfully pickup wireless microphone activity in the 500 MHz to 600 MHz frequency range (i.e. something I can take to an event like a Nascar race or a sporting event to be able to hear the commentary from the wireless mics used by the media members). My understanding is that the majority of the modern wireless mics that are used with a video camera are on the 500 MHz to 600MHz range. I purchased a Uniden Bearcat BC125AT, but it appears that the frequency range only goes up to 512 MHz. Any suggestions for a device or method that would enable me to be able to lawfully listen to the 500 MHz to 600 MHz range (wireless microphones). Thank you and my apologies if I've butchered any of the terminology. I'm a newbee.
