WSJT Download Weak Signal Communication Software WSJT-X, WSJT, MAP65, and WSPR are open-source programs designed for weak-signal digital communication by amateur radio. Normal usage requires a standard SSB transceiver and a personal computer with soundcard, or the equivalent. SDR-style hardware including the SDR-IQ, Perseus, SoftRock, and FUNcube Dongle is supported by MAP65 and WSPR. SimJT is a utility program that generates simulated signals... Read more
E-mails have gone out to an undetermined number of US radio amateurs from theUtilities Technology Council (UTC), approving the stations’ intention to use 630 meters (472-479 kHz) and/or 2,200 meters (135.7-137.8 kHz). “UTC has determined that your proposed Amateur Radio station would not operate within a horizontal distance of one kilometer from a transmission line […] Read more
