Model Forum / Radio Controlled / Water Models / May 2007Can a 72 Mhz receiver use a 75 Mhz crystal?
How flexible are receivers to using different freq crystals? I would like to use a VEX 75 Mhz FM PPM TX sending to a 72 PPM receiver with a 75 crystal plugged in. I have never done this!! And i think that it will not work,if i remember right! The cost for a crystal is to little(almost 10$)...

Normally you adjust a component to "tune" the circuit to a set frequency a bit like tuning a guitar but you need several pieces of test equipment to do it |
