Receiving \u00a0with a HackRF One, SDR#, and MultiPSK<\/strong><\/p>\n

by\u00a0Mario Filippi (N2HUN)<\/strong><\/p>\n

The HackRF One is a Software Defined Radio manufactured by Great Scott Gadgets (www.greatscottgadgets.com<\/a>) and has been on the market for a few years. Having used an SDR-Dongle for several years I felt it was time to \u201cstep up\u201d to this wideband (1 MHz – 6 GHz) receiver to investigate a broader breadth of the radio spectrum, so one was purchased from Sparkfun (www.sparkfun.com<\/a>).<\/p>\n

Recently I performed a rudimentary evaluation of its ability to receive DGPS (Differential Global Positioning System) beacons found in the Longwave band \u00a0between 285 \u2013 325 KHz; this frequency range is well below the HackRF One\u2019s stated lower receive limit of 1 MHz.<\/p>\n

\"100_5864\"<\/a><\/p>\n

DGPS beacons, when tuned using SSB, emit a distinctive warbling sound, and at this QTH, depending on band conditions and time of year, can be heard as far away as the Midwest. Winter brings the cold weather but also excellent conditions for receiving these beacons, some of which were former marine radiobeacons retrofitted to provide greater DGPS accuracy.<\/p>\n

The HackRF One, when used with SDR#, MultiPSK, audio piping software, and a good (43 foot vertical) receiving antenna was able to receive DGPS beacons, and two screen captures are below:<\/p>\n

\"DGPS<\/a>

I was very pleased that the HackRF One was able to receive DGPS stations, though tuning them in seemed a bit trickier than with a standard RTL-SDR dongle.\u00a0 Since this time of year is not optimal for monitoring DGPS beacons, as well as the Longwave band in general, it\u2019s reassuring to know that come winter I\u2019ll be able to do some DGPS beacon DX\u2019ing with the HackRF One.\u00a0 However, anyone with a shortwave radio and a good antenna can avail themselves of DGPS beacon hunting, just tune down between 285 \u2013 325 KHz and listen for the distinctive warble.<\/p>\n

To decode, look into an excellent program like MultiPSK (http:\/\/f6cte.free.fr\/index_anglais.htm<\/a>). 73\u2019s!<\/p>\n

Thank you, Mario, for another great post!<\/em><\/strong><\/p>\n

When Mario told me he had purchased the $299 HackRF One, I\u00a0was hoping he would do some guest posts about this SDR–DGPS beacons was use I had never thought of. Looking forward to more of your guest posts, Mario!<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
