Hello all,
Seems like someone thinks that stray RF comes in the servo leads and not
the antenna, sorry guys, if your receiver gets gliched it is probably due
to s strong signal in or out of band overloading the receiver. Could just
be noise picked up through the antenna.
This doesn't say put ferrite beads on you antenna, if you did you wouldn't
even pick up your own transmitter very well.
It is possible that brush noise from the servos could get it to the receiver
trough the servo wires. Common mode filtering (ferrite toriods with the servo
wires wound through them) will not fix that. There should be filtering in the
receiver for that plus filtering inside the servo. Someone suggested putting
bypass caps across the servo leads, that should help especially with series
inductance to form a low pass filter. L/C filters on the servo motor would
probably do even more good.
