   economical  RDF unit for those  lowfer air beacons ......

   they don't show up in the sw listening NGs or the  receiver  searches   
   on ebay .. so they usually remain a bargain.  think  some  have a   
   motor drive on the  rotational antenna on top  and  adjusts it's  self   
   automatically  as you move around ........ keeping the direction set !   
      
   might be good for BCB listening as well !   
      
   just a thought ........
