"Also, the signal has been considerably weaker and with a lot more QSB than I see on either AO-73 or EO-88."
JY1-SAT is currently running in safe mode with only 30 mW of power out, so it's 10 dB weaker than AO-73 (currently at about 300 mW in full sun) and about 13 dB weaker than EO-88 (in sunlight - running 500 mW).

Hi Kevin, I did a TLM run with JY1SAT about 90 min ago and left the decoder running (as I do with all my TLM programs) AOS in about 9 minutes here, and assuming the TLM is on, I'll let you know if JY1 Dashboard takes off or not.
17:19z , JY1SAT came right up, and it Dashboard is locked and decoding fine. I have about 11 frames and am at 9 deg EL.
Just for comparison purposes, I have my AutoTune range enabled, and set for 0 and 3500 73, N0AN
Also, the signal has been considerably weaker and with a lot more QSB than I see on either AO-73 or EO-88. I'm seeing a LOT of polarization fading as I switch back and forth between a RHC Eggbeater and an X200 Colllnear. Even at 40 deg EL, seeing polarization fading on the RHC EB.
Also noted, doppler tracking is not as "perfect" as it i s on AO-73 and EO-88. I assume this is due to some slight error in the TLE's
I also just adjusted my tracking Auto-Tune high end to 6000, as it lost some decodes with the high end set to 3500

Hi All, Is anyone else noticing any issues with the JY1-sat dashboard? I can start it with the sat present and it will instantly lock and track, next pass it will ignore the signal, kill it and restart it and bam instant lock.
