Hello, Jim,
I just touched on this in a recent post to this reflector, so I will
summarize with the Readers Digest version.
ARRL has an info package on Cable TV. It is a reprint of a 3-part article I
wrote for Communications Technology, the Journal of the Society of Cable
Television Engineers. It is available from ARRL HQ for $2 members, $4 non
members, to cover the printing and postage costs. I note that you are
member, so I will send it in today's outgoing mail.
If you still have questions after you have read it, give me a call here at
HQ. My direct line is 860-594-0318. I will be out of the office on Friday
and Monday.
73 from ARRL HQ,
Ed Hare, W1RFI
ARRL Lab
