[TenTec] Mobile Power Source for Scout

[Jliving39 at aol.com]

Folks,
     I use a Scout mobile at half power with very good  results.  Still have 
some noise though no matter what filtering I  use.  The Explorer is fairly 
quiet though, but not perfectly quiet.
     My question:  Does anyone have any  suggestions for a stand alone power 
source for mobile folks running about 25  watts looking for a noise free 
environment?  
                                Thanks, Jim, K4CFA
