[MilCom] Question

[Amtrak35 at aol.com]

Basic scanning and recording still the same.. Still using my old vox  
recording software
on computer with old Bearcat B780 radios for last 20+ years.
 
 Mode s has gotten cheaper as well with various low priced computer  
dongles instead of
high dollar radar boxes.You still need a good vertical antenna to capture  
signals though.
 Some ideas here from way down under..
