Recorded the Artsat1 Invader CO-77 satellite
I saw an announcement that Artsat1 Invader CO-77 aka ITF 1 was going to make a pass over Europe. I recorded it by having the laptop with the gpredict software also run audacity to record the audio from my handheld transceiver, so the audio isn't brilliant, but it's something. I reported the pass and the recorded audio to the Artsat team. This satellite is even in a lower orbit: the entire pass horizon to horizon was in 7 minutes. In the end I have 1 minute 40 seconds of usable audio, with everything the satellite offers: morse, the digitalker and AX.25 frames. The voice says: "Konnichiha Uchu" which translates to Hello, space!. Update: with fldigi I decoded the morse code:*HELLO, SPACE*Update: the pass was also recorded by PE0SAT and DK3WN: INVADER Digi-Talker active - DK3WN SatBlog including decodes of the AX.25 frames. And the transponder file I used: /home/koos/.config/Gpredict/trsp/39577.trsp with:[FM Downlink] DOWN_LOW=437200000 MODE=FMNow I have adding frequencies for an existing satellite covered, I wonder about adding an entire satellite.
