[RVRC] Navigation in the 1940s: The Four Course Radio Range

[Joe Cro N3IBX]

Hello Gerry,
                  I found the "Youtube" URL tio be most interesting. Not 
only from the technical standpoint, but for something I've been trying to 
find out about for a long time. I had originally thought it was for a "VOR" 
navigational beacon, but instead I discovered it's probably for a "Four 
Course Radio Range" navigational beacon system after viewing the uRL on your 
post.

I appear to have a (somewhat if not totally) complete Four Course Radio 
Range beacon  transmitter, controller, and antenna setup, made by "Sparton" 
(Sparks-Withington) company sometime in the late 1930's - 1940's. by the 
Sparton (Sparks-Withington) Co. It has the N's and A's written on the front 
panel to control that segement of it, and other controls of which I know 
little or nothing about. I've been seeking to find out what it was used for, 
and I think the link you sent gave me the answer!

If you know of anyone into the history of Aeronautical navigation, I'd like 
to ask them some questions, etc to find out more about it. It came from a 
old air field near Kansas City,Mo. along with some WWII Comm gear.

If there is anything that you, or anyone on the reflector might know about 
this, please either contact me or (if possible) forward this note to someone 
to have them contact me.

Thanks in advance for any help, or allowing me to help someone else with the 
devices I have.

Very Best Regards,
                              Joe Cro N3IBX
