fm crystal -

are all 75mhz fm crystals the same? I know there are negative shift and positive shift recievers, but are the crystals the same? I wanna know what will work with my jr xs3 radio, and yes, I know its synthesized, I have 6 standard recievers that need crystals.
It's "Dr. _paralyzed_" actually. Not like with a PhD, but Doctor like in Dr. Pepper. |

My info comes from a Novak XXtra synth reciever. if you look at the first number there is two differing types, first there is the hitec/futaba (top numbers on the POT and there is the KO/Air/JR side (bottom). Looking at that, I figure a futaba crystal will work in a hitec and vice vera. the others will mix and match on their side (KO/Air/jr). I personally seen an airtronics reciever with a Jr crystal work with a JR transmitter(XS3)
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise |

What channels do you need? On 75MHz FM, I assume?

Duh! I forgot you mentioned that your Tx is synthesized. Lemme take a look at what I have when I get home tonight. I should have a couple I can send your way. I believe I may have a CH65 and CH70, 75MHz FM for Airtronics...should work for you.
