Yes the 3600 is a JR compatable rx however you cannot use the JR single conversion crystal. Never mix brands of crystals in the device of another brand.
As you described using a single conversion JR Rx crystal will not work in your Hitec Rx.
Order a new dual conversion Hitec Rx crystal (blue stripe) on the channel # of your choice.

Well, to a degree. The xtal you're plugging into the rx needs to be close to the channel it was tuned for. I know someone's going to come on here and say it needs to be the exact same channel, but in reality, it needs to be close (within 60 Kc ... 3 channels either way at the most). If you get too far away from the channel it was tuned for, you'll run into signal loss and weaker channel rejection.
