Tour 6 — 1.2026
Carrier: This time i used a GPSDO-modded SDRplay RSP1B with GNU Radio and some FFT magic PPS: GPSDO-PPS together with IC-7300 audio on a scope - cursor measurement (using calibration delay from 18.05.) Pulse: IC-7300 USB-audio recording in Tenacity to count samples
Tour 5 — 1.2026
Carrier: free running IC-7300, WSJT-X via USB. Used the calibration and first run PPS: GPSDO-PPS together with IC-7300 audio on a scope, shifting cursors. Using calibration delay from 27. april Pulse: USB-audio to Tenacity and counting samples
Tour 4 — 1.2026
Hello, first submission here. I just did some simple measurements using IC-7300, WSJT-X and Audacity to compare the calibration carrier/pulse with the unknown ones. Averaging was done in mental arithmetic only :-) No PPS measured. I heard all transmissions but used only the 80m run, as it was the cleanest. I try to come back next time with some GPSDO stuff. Cheers...
