Hi,

Unless I missed something we are talking "tampering" with our own gear - 
our own possessions. I would be reluctant to ever so much as touch 
somebody else's consumer equipment. However I have bought brand new 
radio gear and after running a day or two turned it off, opened it up, 
and customized it. None of that stuff failed to run as expected. Other 
gear I just opened up, tearing the "Do not open - no user serviceable 
parts inside" nonsense tag. I satisfied my questions about how it works 
and how it was built. How awful that some of us actually build 
electrical equipment from scratch!

YMMV.

73,
