I'm trying to sort out electrical noise upsetting many of my clubs radios.

I’ve had moderate but inconsistent results with separating radio wiring
and
use of ferrite beads.

Does anyone know of any on-line info / guides to reduce squelch problems?
(Especially with regard to squelch being upset by electrical noise from
chargers, voltage converters, digital instruments and data wiring).

The problem with cockpit devices causing the need for more aggressive
radio squelch setting seems to be getting worse. Winding up the squelch is

easier than minimising the ‘interference’ but I feel it’s like using
earplugs
instead of fixing a noisy wheel bearing.

I’ve seen and used lots of useful suggestions scattered through numerous

topics on RAS and a sprinkling of possible electrical noise fixes on
Google. I
would really appreciate a pointer to good info and any ‘golden rules’.
