Lack of shielding:
So here’s what the stock mic cable consists of. Interestingly there’s a black wire, which wasn’t connected to anything at either end.
Appropriately shielded cable?
I got hold of a cable with shielding of sorts… but is this enough? The plan, would be to use the red wire for the electret as it’s covered with braid. Problem - I’ve been advised not to connect the shield at the mic end, and only at the radio end. The thin, uninsulated wire has continuity to the braid so I can’t use that separately.
@MM0FMF - would that work, or should I just get another cable?
