Hello David,

Have you tried a modulation change, ie PCM to PPM or vice versa ?
I have tried PPM18 and PPM24 not SPCM20 (JR)

Wonder if your TRANSMITTER is being swamped.
Can you try another tx with the same Rx ?
I have a MC15 and i have already tried this receiver in a little electric glider (with a speed480 engine), nothing has been detected and I have flown two times.

Have you been able to look at the spectrum analyser when ground testing ?
No sorry.

Does the radar head rotate once every 7 seconds ?
Yes


Thanks
Jean-Philippe
