The FS8 has been air tested to over 5 miles in the OUTLAW system and we demoed 3 miles ground-to-ground on Wednesday with a Futaba 9CAP and 800 mw output. The range of FS8 is very far beyond visual range at 72 MHz.

One possibility is a transmitter that is probably way off frequency. It may work with your JR radio because it is broadband enough to tolerate the error.

We could test your FS8 receivers for proper tuning or even check your transmitter calibration, if you like. Please call Tech. Support at 301-668-4280.
