[Amps] Relays

[Pat Barthelow]

I once used some solder wick lengths as  a flexible RF conductor at various places in an HF amp, that needed a small amount of movement flexibility.  Seemed to work OK,  Incredibly fine, woven copper conductors.  You have to be skillful to solder short lengths, and also prevent the Wicking from defeating the flexibility goals.    I wonder though, with the saturated nature of the woven copper and
solder flux, that it may be lossy, and heat, a lot,  with QRO.   Any thoughts?

All the best,
