Obviously you have never worked in the communications field.

That action is referred to as "Active Ambient Air Cooling". The flapping 
door helps to move cooling air into the enclosure.

But seriously,

I believe the 500 card has an LNA on it. Is there a difference if you 
switch it on or off?

Loose connections tend to manifest themselves more at lower frequencies. 
A problem that's only on channel 2 would make me look at possible 
mechanical problems.
