Jim,
I observed yesterday a new and different behavior when binding a Nano Rx to an XPS Futaba transmitter module in my Futaba 9C transmitter.
I configured the Nano for binding with its LED blinking fast. Then I turned on the transmitter while holding the PROG button. When I released the PROG button the bind did not occur. At the time I had the transmitter located about two or three feet from the Nano Rx. It finally completed the binding when I moved the transmitter antenna to within two inches of the Nano.
I have a second Futaba Tx module and I put it in the same transmitter body and repeated the test with the same Nano Rx. The binding process completed immediately with the Nano even when the transmitter was several feet away.
After performing another "two-inch" bind with the suspect transmitter module, I performed a range test with the program button pressed for low power and went more than 150 feet away without any loss of control.
In my experience, XPS transmitter modules (both Futaba and JR) seemed to always successfully bind with XPS receivers when located several feet away. This working distance is typical during bench testing and setup.
What I have now is a transmitter module that won't bind with a receiver until it is located two inches or closer. This same transmitter module and receiver pair delivers good range in a range test.
I'm grounding the transmitter module, and in the meantime kindly want your opinion about it.
Thank you,
Paul
P.S. Just opened the module and checked the u.FL connection - it was seated well on the internal RF module
