[MilCom] Scanning satcom

Hi Kevin,
I bough this antenna on ebay http://www.bhigear.com/trivec-av2040-2-satcom-antenna.aspx
The satcom part of the band is a bit noisy here so i think i need the high gain type.    
I also use a radio shack in-line amplifier.  All channels NBFM. I record 
with a Icom IC-R20 with the gain on it set to 5 or 6.  Too much gain and the signals get noisy.  The squelch is set to auto and seems to cut out most of the secure comms.  This leaves the pirates as the biggest problem since i am usually not at the scanner to tend to it.  My thinking now is that since most clear comms by the military are short and not followed immediately by a response in the clear, might as well have the scanner not stay on any freeq for very long.  No delay and a negative delay (force resume) of 4 seconds is what i'm trying now.  That way it won't sit on a pirateted channel for very long in each scan cycle.  This was how it was set when it caught the Jolly activity.  For the Zombie comms, i was at the scanner so i could get the freq and stop the scanner on that channel.  
 
Paul

I imagine this has been discussed here in the past, but what would be 
the best mode for listening to these comms?  NBFM?  Also, are you using 
any special antenna set-up to catch this traffic, Paul?

Thanks in advance, and thanks for sharing the link to the audio!

Kevin
