[hpsdr] predistortion

[Warren C. Pratt]

Hi Frank,

Congratulations on the new computer and the results you're achieving.

Having Atten on TX set automatically by software is a good idea.  As is 
often the case, it's not quite as simple as it sounds.   No commitments 
--- however, we'll consider the pros and cons of an option of that type 
for a future release.

73,
Warren  NR0V
