Congrats to Joe Long for his excellent article in this months  "ER" magazine issue on the BC-1206. This little receiver and its other variants allowed single engine and larger aircraft to navigate the A/N airways with precision. Arriving at Destination with an A/N beacon nearby  the aircraft could shoot a non-precision approach and penetrate  low ceilings.   Once near the airport traffic pattern the pilot could receive instructions from the tower and acknowledge by rocking the wings or flashing a light etc. A lot of capability in a 4 pound box. You could even install the receiver with a battery   in a aircraft that did not have an electrical system.
 I  began my aviation career  using this type of receiver and it became an old friend. It was simple, reliable, and easy to use.     This two part article is very compressive (8 pages in Part one) and has excellent references. Job well done Joe.
