[ARC5] ARC's first range receiver of 1929

Al,

Thank you very much indeed for the amazing resources. The 1930 Aero 
Digest ad would then suggest that the A.R.C. only developed these 
receivers and licensed their production to Stromberg-Carlson. Interesting.

When you allow them, sometimes they give you money for the right to use your “thing”. The way you allow them is to give them a license to use the patent. As a “big company” you likely already have licenses to various patents. They may be your own patents. You also might have done a “swap” with somebody for the license (I’ll let you use mine if you let me use yours ….).

That GD group faded away and RF Communications (which became Harris RF) popped up in its place. Yes, that’s a *very* abbreviated / simplified version.
