RE: 2 or 3 ch. FM recievers
It's on 75mhz, I believe airtronics uses pos. shift , so any pos. shift receiver should work.Also JR should work,and I would think there are recievers out there that will work with pos or neg. shift , so if any one has one used cheap pm me.Almost all aftermarket manufactures on 72mhz work with any shift.
