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.
