[ROVERNET - UK] Calling Rovernet Brain trust!!!

[Kent Kinard]

Very interesting...I have much to learn about SU's.  Thank 
you, John.  This may explain some tuning problems with the 
3L7 in my P4.  I will have to check all the areas 
mentioned.  Rovernet to the rescue again.  Hope some of 
this works for you, Ben.

Rovereeducatedly,
Kent K.
