Regarding Observation 1527482 …
I’m not getting any STRAND-1 decodes with SatNOGS, but have good results with the UZ7HO High Speed Sound Modem. This was near a direct overhead pass with very strong signals, but zero SatNOGS decodes.
Any suggestions?
From what I can see, probably the modulation index of their FSK is larger than the default that we are using. So our low pass filter may cut significant portion of the signal. I will check my IQ recordings to confirm this.
