I started building model airplanes back in the late 50’s, I lived for working in our garage building with my father. We would go fly our newly built or repaired airplanes every weekend. Back then a good flight was getting off the ground and a great flight was landing within walking distance. This video was taken in 1959 while at a flying meet.
   Most of these radios were used by my father or myself. They date back as early as the late 50’s, some of the newer ones were manufactured in the 70’s. These radios cost about twice as much as a new radio today. The reliability was only as good as the operator, the early radios had to be tuned every time one went out flying.

Below are images from back in the 60’s that were in my fathers archives.
