Hello Jeff,
              Very eloquently put, your mail was a credit to this bbs and of 
course I agree with you 100%. Personally, I'm completely self-taught and 
operate a 100% home brew satellite station. My intention was to breach the 
... "can't afford it" ... excuse. Your point about possible congestion on 
the bands is a very good one indeed.

Have a nice day.
