I picked up a receiver made by "Tower Pro"

The ad said "FM 72Mhz 6 Channel Micro Receiver Futaba JR GWS Sanwa "
so I thought I was golden. Now I'm realizing that all the supported brands
meant brand of servo, not brand of transmitter.

Does anyone know if this receiver is compatible with the Futaba camp of radio?
If it is (and I assume it's single-conversion) does anyone know how I should go
about finding a crystal for it? I haven't had much luck getting info from the
seller. I think there's a significant language barrier.

I have a feeling I'm going to be in the "poorer but wiser" category on this one.
