RE: RAM Beacon causes servo glitching; Help
TFF:
Grounding the 9v beacon system with the radio reduced the glitching...hard to say how much, maybe half as much.
Then grounding everything to the landing gear ... it was Katy bar the door, glitching like never before. So much for that idea.
I guess what we have is an EM field generated by any wiring in the 9v system, and that only causes a problem because, in the beacon mode, the field is varying, regularly, in strength, generating somethine akin to the EM field of a running electrical motor?
The "frequency" of bright to dim back to bright is about once every three seconds.
The reason the glitching is greater with the antenna aligned with the fuselage c/l is that it is then roughly parallel to the 9v wiring, and when I had the antenna at right angles, it picked up very little of the em field?
