Thanks for the insight!  Is there anything that can be done to help it?  One 
thing I don't understand is how the db can tell us if the channel can be 
tuned?  Can't the assumption be made that if we have a  channel in our list 
it should be tunable?  I am not trying to be snarky, I am trying to gain 
insight.
