Paul,
Of course, I was just 'raggin' on you. Understand, I'm a ham (Extra class, thank you THE OLD way) but most electricians have never heard of velocity factor, which of course is a major problem in telecom and rf circuits. Brief 'splanation for those reading this junk (junque ?). Electricity travels, ostensibly, at the speed of light.....IN A PERFECT MEDIUM... however, wire is not a perfect medium and the speed has to be adjusted for the path, hence, the velocity factor. Now that everyone is asleep, I'll tiptoe out.
