RE: Why isnt my Futaba working with Jr receiver?
Faisalk is correct. Again this is a difference between the USA and the rest of the world. We are allowed to change crystals in transmitters, from top to bottom of the band. I don’t know if the USA’s FCC is just being cautious or if there is good reason because errors in the crystal get magnified twice as much at 72 Mhz as they do at 35Mhz. Hard to believe that’s the reason though, because in the USA Multiplex has a dispensation from the FCC that allows Multiplex users to change the crystals without needing a qualified technician to re-tune the radio! Perhaps it suits Futaba and JR not to apply for dispensation like Mpx did, so that they boost sales of modules?
