John, I agree totally. Seems today someone ask a simple question and some get so caught up in it and twist the issues and before long all have forgotten the question.
To me also the answer is simple. As so many have said if it looks like a duck... 73, ron, n9ee/r >From: John Gleichweit <[EMAIL PROTECTED]> >Date: 2007/10/13 Sat PM 12:24:15 CDT >To: [email protected] >Subject: Re: Re: Repeater output in amateur satellite subband (was Re: >[Repeater-Builder] > >Let's just make the discussion extremely simple. <br><br>What does the >equipment do?
