I disagree. Twisted wires do not function as a choke.
Dirtybird,
They do act like a choke. The twisted wire is a small diameter long stretched coil. Over here ALL longer leads are twisted so they do not pick up and/or transmit RF signals to and fro, and it seems to work very well. I twist all leads quite tightly, and heat seal the twist using a heat gun to make it permanent. As an additional advantage, the leads become more flexible and less prone to fatigue failure. Too many goodies to just pass up.
A choke is many turns of wire usually over an iron core. Just a few twists over no core cannot begin to create the inductance to call it a choke.
I have observed quite a few hot airplanes at contests over the years. Some have had twisted leads but most have not. They all seem to work equally well.
To get the benefit of twisted leads you need balanced input to the circuit. None of our equipment has balanced inputs.
Twisted leads fall into the grey area created by some partially electronic literates who think it might help. Note that very few of the manufacturers provide twisted leads on their pigtails or on their extensions. Its a waste of time and money.
