It all depends on the wireless system being used by the microphone -- there will be a dedicated receiver that the sound reinforcement system is using. Various models use UHF or VHF frequencies, so while the signal is technically an FM signal, the frequency range is outside of that of commercial FM radio (87.5 to 108.0 MHz). You would have to use a TV tuner, the Griffin RadioShark for example would not work. The AirPort uses a completely different range of frequencies.

Here is information from the top 4 producers of wireless systems

http://www.shure.com/booklets/intro/...o_wireless.asp

"Shure wireless microphones and PSM systems designed for use in the United States operate on standard VHF (TV channels 7-13, 174-216 MHz) and UHF (TV channels 14-69, 470-806 MHz) frequencies. Most U.S. cities have any number of local televisions stations, whose operating frequencies must be taken into account before choosing a wireless system frequency." So the manufacturers have charts of good frequencies for each city.
