John, the trouble is at my end, caused by my nincompoop of a
dis-service provider.

If previous experience is any guide, it will take weeks to sort it
out. When it comes to managing Windows, OE and the Internet, I'm a
mere novice.

( The most important thing about ferrite rings is their size. You
can't get a dozen turns of speaker cable on 5/8" diameter rings. )

I'd like to make a 1:1 balun,

===========================

Wind about a dozen turns of twin, stranded, 18 AWG,
clear-plastic-insulation, speaker cable (or similar) around a 2"
diameter ferrite ring. About 3/8" cross-section. Permeability
200 to
500.

And there you have it. Speaker cable is better than coax on both
mechanical and electrical grounds.
