If you look at the received signal strength on the downlink, the crew are  
saving the radios from overheating by having the squelch turned up. i.e. the  
radios get a big rest over the oceans. Unless you put in a fairly large signal  
then the squelch drops out and part of the transmission is lost. Result: It  
sounds 'choppy'

I  believe it has to do with the relative position of the antenna(s) on the 
ISS  and all the "stuff" connected to the station that run in different 
directions.  I can see how the antennas might be blocked from out "line of sight" as 
this  module or that solar array "gets in the way" on a given pass.

Any other  thoughts about it out there?
