There's a big problem with consumer LNBs - they drift, and drift badly! One way of correcting this drift is to monitor the telemetry beacon, determine the actual received frequecy of the beacon and hey presto - we have the offset!
Quite a bit of coding involved, but when you decode BPSK you actually have the offset if you pay attention to the code. Add a nice waterfall so the user can select the beacon, add a bit of funk and we're more than half-way there. Here I'm plotting drift versus time.
Also it's nice to see Es'Hail 2 being used more as people get their systems together.
Code will be in 3.0.7 - within a week I hope.
