RX Shielding..
 

A guy from a neighboring club called by our field on Saturday morning ...they had a fair bit of Interference Issuesas of late..

However after wrapping their RX's in this silky Silver woven type fine cloth the problems seemed to lessen considerably.. it looks and feels a bit like Textured film covering, you wrap your RX in it and tie loosely at both ends ...like a Christmas cracker...You do have to earth the cloth ( you can solder to it ! ) but thats it.

Anybody any thoughts..? seen it before..? Used it at all..? Would it allow a less prescriptive placement of you RX ..? ( in relation to pumps etc )

The Gentleman that supplied it is involved with the design/construction (and specifically the shileding issues) of the MRI scanner in Hospitals.

RE: RX Shielding..
 

Sounds like a Faraday cage. As far as I am aware, this should prevent any signal from disturbing the RX. However it will not protect any stray signals from hitting the antenna (fortunately, otherwise you would have no control).

I am a great fan of solving problems rather than masking them so would not try it myself. Something is causing the interference and my guess is it is internal (otherwise the stray signals would still arrive through the antenna). I would be keen to find out where the problem lies.

The problems encountered with interference apparently manifested themselves shortly after a new Mobile phone mast was made operational close by... don't know whether that relevant.

I can't see it being much use when the antenna and servo wires
(perfectly good conductors) still exit the receiver. Also, how would one know if it was keeping out stray signals, or attacting them.....

I have noticed that some of the newest receiver designs put part of the circuitry in a metal can for shielding. I always wanted to try this when I built radios (R/C). This mesh probably accomplishes somewhat the same thing. It doesn't mean you can you violate the rules of staying away from the fuel pump and ECU(FADEC) with antenna and wires internal to the model.

Possibly the shielding protects from some lower frequency interference sources. Of course this is speculation on my part with out hands on tests.
