Dave,

I'm sorry, but don't know the answers to these questions.   I did 
initial set up on mine back in 2008 and haven't played around with it since.

I only use a single antenna out from the tuner.  This goes to a Alpha 
Delta 4 position switch mounted under the top of the desk.   From the 
switch, out to 3 antennas and a dummy load,  so I never switch antennas 
  on the tuner.

73, Steve KW3A
