Please note that the advertised range is only under ideal conditions such as:

  • Fresh batteries
  • Absolutely no obstructions between the radios (for example communication over water or from mountaintop to mountaintop)

To maximize range, please make sure that the batteries are fully charged.  If your radios use AA size or AAA size batteries, then you can try regular alkaline batteries.

Channels 8 to 14 are locked on low power per FCC regulations, so try using channels 1 to 7 or channels 15 to 22.

On some models you can adjust the transmit power level.  Make sure it is set to HI.

Please note that use inside a building or inside a car will reduce the range.
