Below you'll find links to every area of interest with the Part 15 hobby. Every effort is made to keep this list of links current. If you should find any broken or out of date links, please send us e-mail so that we can repair the site. If you have links to add, please feel free to e-mail them to us as well. Information about Lowfers Lowfers are a close knit group of radio experimenters who operate beacons to explore the mysteries of low frequency propagation. Most of these experimenters are also amateur radio operators, however, no license is required. The best source of information on this topic is "The Lowdown", the official publication of the Longwave Club Of America. Their web site is also a great source of information about LF experimentation. Visit them at: http://www.lwca.org/ There is also an e-mail reflector that many active lowfers subscribe to. The list is used to discuss topics ranging from antenna design, noise blankers, CCW, and BPSK, etc. During the Winter DX season, the list is also used to report openings and pass along reception reports. To subscribe; visit the link below. You'll see a box that says "Select List". The list name is "Lowfer". To subscribe to Lowfer List: http://www.qth.net/ Links to Lowfer Pages These sites are directly related to "Lowfer" operations. You should be aware that there are also amateur radio LF operations (in Europe and elsewhere), experimental licensed stations, and research groups like AMRAD.

Below is a screen capture of Lowfer beacon, TX in Texas. Bill has one of the best signals on the band. This image was taken on December 18, 2000 while Bill was transmitting on 189.100khz. The signal faded in and out for over an hour, yielding lots of screen captures like this one! This beacon is 608 miles away, and was copied using an active tuned whip.
