 Reminds me of my early
 days on HF, with other hams on the local VHF 
 repeater while comparing low-band antennas.
 "Now I can hear a japanese station on 160.
 He's very strong with my new 
 antenna."
 "Here, too.
 What did you think. But I can also hear three ZL's and
 four 
 VKs in the background".
 .. etc etc.
 If you know exactly
 who's out there, where and when, you can also hear 
 him without any difficulty.  Similar applies
 to smart black boxes.
 
 73,
 happy christmas and hope to cul via real airwaves,
     Wolf .
