RE: Re: OT? Radio monitor / cable extension

["Brian G. Reynolds" <brian.g.reynolds@xxxxxxx>]

Blimey! at those sort of distances I can take the monitor to work with me!
actually not quite.

I was only thinking of around 2m tops. Just a bit too short as it is now.

Just also got a message from Richard Malcolm-Smith, thanks Richard, and I
have a number of these BNC connectors on the rear of my monitor, are they
any use to me? never have known what they are for.
