Let's Listen To LF Radio Navigational Beacons Using Vintage RDF Radios

I decided to put some vintage radio direction finding radios to use just to see what local aircraft beacons I could hear in the LF range. These radios did the job and did not need to be real sensitive or selective like I talk about the newer radios being, since they were only needed to be able to find the direction of the station for bearing purposes. I should have pointed that out more in the video. But for DX'ing these beacons, the newer and more selective radios do pull in more stations, but it also depends on the antenna you are using. Small loop antennas work well here as you can null out local noise sources. Here are some links I mention in the video: Look up beacons by frequency: http://www.dxinfocentre.com/ndb.htm What is a non-directional beacon: http://en.wikipedia.org/wiki/Non-dire...
