Good Morning,

Charles is very knowledgeable in the technical arena, and is due great 
respect.

Dr. Lankford is not without the same knowledgeable technical aspects, 
and is also due the same respect.

I would suggest actually performing an experiment with both 
possibilities.  I believe it would be beneficial to conduct such, and 
then provide the results.

Nothing would be damaged nor hurt to try this comparison.

Bear with me, as the more we attempt to improve these wonderful 
receivers, the greater the collective knowledge is aided.

Humble Regards to all.
