In my previous post (Ref.1<\/a>) I examined how the RTL-SDR with the up converter can be used to receive the LF\/MF\/HF bands. Low power radio navigation beacons are located in the LF band and can be received by the RTL-SDR. Figure 1 shows a table of LF radio navigation beacons located in the Toronto area (Ref.2<\/a>).<\/p>\n\n\n\n <\/p>\n\n\n\n For comparison purposes, I used a Sony ICF-7600 shortwave receiver with a whip antenna, an SDR-IQ and RTL-SDR\/UpConverter on a Buddipole antenna. Figure 2 is a video showing the results. Each station’s call sign is sent out in Morse code. The RTL-SDR is tuned to USB with a 1200Hz filter bandwidth and tuned 600Hz below the carrier frequency to put the on\/off carrier 600Hz in the middle of the filter bandwidth. <\/p>\n\n\n\nFreq KHz<\/td> Call Sign & Pwr W<\/td> Location<\/td><\/tr> 248<\/td> KZ 50W<\/td> Buttonville, Ontario<\/td><\/tr> 257<\/td> TZ 25W<\/td> Gibraltar, Ontario<\/td><\/tr> 341<\/td> ZLP 40W<\/td> Meadowvale, Ontario<\/td><\/tr> 368<\/td> ZYZ 25W<\/td> Queensway, Ontario<\/td><\/tr> 391<\/td> OO 50W<\/td> Oshawa, Ontario<\/td><\/tr> 403<\/td> ZTO 50W<\/td> Woodhill, Ontario<\/td><\/tr><\/tbody><\/table> Operation<\/h2>\n\n\n\n
