NOTE: These radios are very broadband, and can be inadvertantly used on AMATEUR RADIO frequencies as well as commercial/air band channels. For hobby use, you may want to program these radios on the UHF band, using the FRS frequencies. See below. How do I know this? I am a HAM (amateur) radio operator....which requires a licence, much like this sport, to use the allocated frequencies.
The VHF (2-METER) ham band is from 144.0 - 148.0 MHZ and the UHF (70cm) band is from 430.0 to 450.0 Mhz. Take note that many key fobs and other low power RF devices operate at or near 433.0 Mhz, so these frequencies should be avoided.
