C-band (3.9-4.2 Ghz) or L-band (1.5-1.6 Ghz)?
The waterfall screenshot shows the down-converted C-Band frequency from the LNB, and that happens to be in the middle of the L-Band... which works out pretty good for SDR selection as you can use the usual RTLSDR type device to pick up this frequency.
One thing to note, the 25Mhz crystal oscillator in the LNB has pretty bad thermal drift and this will push and pull the down converted frequency out of the VFO bandwidth. Not a huge problem at this part of setting up ground station since manual tracking of the dish is needed, manual tracking of the VFO can be applied at the same time, but long term data reception will require the GPSDO modification where a GPS locked clock is applied via a thin coax in place of the crystal which is removed.
Then of course, there is the software and mechanical challenge of moving the dish every 15 minutes or so to track the satellite orbit.
None of this is to take anything away from
@john5990 amazing effort getting up and running. Its cold outside and hes been a real trooper running back and forth adjusting things and getting everything setup and dialed in.
Their are a lot of flights and data on this satellite we have never seen before and it fills an important gap in the system so huge thanks for putting it all together.
