[TenTec] Jupiter - Such a Quiet Puppy

[Bob McGraw - K4TAX]

Are we speaking of internal noise or external noise?  There is a big 
difference.   Actual noise performance requires test equipment and specific 
measurement technique.  Just connecting an antenna and turning up the gains 
actually concludes nothing with regard to receiver noise or receiver 
quietness.

A grounded station/antenna such as using a G5RV needs no ground at all to 
operate successfully.  And it might be that noise is being picked up on the 
ground thus making the situation worse as opposed to better.
