I'm so lost. I have no clue what I'm doing. I used kalibrate-hackrf to get the ppm but don't know how to figure out the gain values. I tried the ones from another HackRF issue on here.

Sorry about that - I have started to put together some better docs. Here is the start: https://github.com/robotastic/trunk-recorder/wiki/Tuning-in-a-System
I'm so lost. I have no clue what I'm doing. I used kalibrate-hackrf to get the ppm but don't know how to figure out the gain values. I tried the ones from another HackRF issue on here.
