I have been trying to solve this problem for hours. I am pretty sure the way it started was when I turned the transmitter on
and accidentally selected transmit when there was no module plugged into the back of the A9. It switched from AFHSS
to ppm. Now, when I plug the 2.4 module back in and turn the radio on, it won't detect it as AFHSS resulting in no telemetry.
I have upgraded the module, receivers, and the A9 to the latest firmware and have done a factory reset on the A9
and still no luck. When I go through the initialization screens after a factory reset, the AFHSS shows up but then it asks me
what modulation I want to use and wont finish the initialization until I select something else than
the AFHSS. Thanks in advance, Ian [/
No Spectra Pro module handy today.
Suggest check out manual pages 27, 57 & 58 regarding frequency changes.
May need to finish the 72MHz PPM sequence before it will allow change back to 2.4GHz.
i.e. select PPM and then any frequency, cycle power on/off.
. Insert 2.4Ghz module and A9 should then recognise the change.
if no joy, then email/phone:
