RF module for spectrum?

[erhard52]

The SRXL protocol used by the newer Spektrum receivers is not supported by the X10+.

As far as the scope output, you are likely picking up the RF transmissions on the servo itself.  All channels are output by the same CPU, so they should all look perfectly crisp.  Turn off the EVO radio after a connection has occurred to see if there is a difference.  You are using clip leads instead of scope probes, so those will pick up everything signal wise, and the servo itself could be the reason.  If in doubt, plug the servo and check the output from the X10+ directly.

thanks for the reply and thanks for the clarification on the SRXL protocol.

ok maybe i was not clear in my description - i did this, i probed the channel output on channel 1 (the clean one) with and without servo - same thing, signal looked crips and i did the same thing on many other channels - same thing it always looked bad. it also did not matter where i fed in the ESC 5V connector. no matter what i did the channel 1 looked good and all others bad.

i agree the unshielded clips is not perfect but in this case it did not seem to matter - but yes i also can probe with the scope probe directly.
as i said i will try another X10 and also another receiver from radiomaster or spektrum.
