I have 2 Corona 72mhz synthesized receivers.

Both receivers will connect and work with my Futaba 6XAS transmitter (crystal controlled), however neither receiver will recognize my Polks Tracker II synthesized transmitter.

I have no problems using a Polks "Seeker" receiver or another synthesized receiver (forgot the brand) with the Tracker.

Any suggestions on how to get these RX to work with the Tracker II, or am I stuck using the Futaba TX with them ?

I prefer not to swap out receivers with the planes I fly with the Futaba if I don't have to.

Thanks
