[ARC5] Flying the Beams

[Robert Nickels]

Since I know many here are also interested in aviation and radio 
navigation, I wanted to share an excellent new website:

https://flyingthebeams.com/

The creator,  Doug Davis, has done an exceptionally good job of 
explaining not only the Low Frequency Radio Range (LFR) but the 
evolution of airborne navigation to the present day, with many 
illustrations and photos that I haven't seen elsewhere.   To his 
credit,  he has also preauthorized the use of material from this site 
for educational purposes,  as long as it is unaltered and attribution is 
given.     An enormous amount of effort has been put into researching 
and developing this site.

To my surprise he was able to find actual audio clips of the LFR in 
operation, which I didn't know even existed!   There are also on-site 
photos of the few remaining intact radio range sites that I've only been 
able to view via Google Maps. In addition to navigation, the "Early 
Radio Tech" page provides a great summary of the development of radio 
with high quality graphical illustrations.

A terrific resource for anyone interested in the topic.

73, Bob W9RAN
