Can't get this working in Seattle with HackRF #83

Closed timothyclemansinsea closed 7 years ago

timothyclemansinsea commented 7 years ago

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.
