I have a piece of coax around here somewhere that I once burned up. I
recall telling you about it. The insulation is bubbled and melted at

traveling wave might have caused that to happen.

It's the consequence of having *two* traveling waves, which occurs any
time the line isn't terminated with its characteristic impedance. Betcha
yours wasn't.
