More support for Airspy? #38

Closed jmhayes-table closed 5 years ago

jmhayes-table commented 5 years ago

My airspy only supports 10 and 2.5MSPS, but in vdl2.h I see:

#define SDRINRATE 5000000

define SDRCLK 1250

So when I build for airspy and run, it says it can't find the requested scan rate. Using what you did for the Mini, I tried 2500000/625 and commented out the two calls to airspy_r820t_write() and now it opens the device, but doesn't seem to decode any data?

`$ airspy_info airspy_lib_version: 1.0.7

10 and 2.5 MSPS are for IQ format vdlm2dev use raw format. Are you sure that your lib and firmware are up to date ? I have seems problems in the past with old versions.
