I recently received a JR 6102 Tx and R770S Rx in a bundle of other items I purchased. The radio arrived sans crystal, so I ordered a JR channel 43 Tx crystal to match the 43 in the Rx.

The problem is, I can't seem to get them to communicate. The Tx appears to function properly, and I have even tested it on a PC with a trainer cable. It is sending signals at least in that respect.

As far as the receiver goes, when I attach a battery and test servo, the servo does initialize, but does not respond to Tx inputs.

I'm at a loss. What further can I do to troubleshoot this issue?

Thanks for any and all assistance.

Just maybe check that the servo is plugged in okay and on a channel you are testing..?

Make sure that the transmitter is set to SPCM in the modulation screen.
