75mhz FM Futaba Dual Conversion Crystals

[Wax Savage]

Hello

I posted this here as sometimes a submariner has some Futaba 75mhz FM Dual Conversion Crystals; TX or RX Yellow tag crystals in their collection they no longer need.

If you do and want to sell them PLEASE contact me as I am looking for them.

Thanks for your time.

Some good news they all use the same crystal.
can't find a futaba one, hitec or airtronics will do.

Stick to a hitec receiver for now, I am too lazy to check futaba high/low band receiver make a different, 19F out side don't help. Definitely high/low make a big difference in 72MHZ. The servo when crazy.

This may work too.

Side note a JR 72mhz receiver in (+) mode will switch to a (-) mode when a JR 75mhz crystal installed.

Some crazy post off my.

Yes, I do have a set on 85, BUT is on most of THE VEX TRANSMITTER.

Hi Cheapsub,

thanks for the tip. I purchased a new HiTec 75mhz ch.77 D/C crystal and a Futaba R168DF Dual Conversion 8-CH 72Mhz FM receiver off eBay, I sent both off to Radio South,Inc to re-tune the receiver to use the HiTec crystal. Waiting for it to come back.

UPDATE:
Radio South retuned the Futaba receiver to 75mhz and matched it to the HiTec crystal I sent. Cost was $20 labor plus $6 return shipping.
