Startup signal glitch #18

Open starvald opened 6 years ago

starvald commented 6 years ago

using rtl_airband or CubicSDR mostly when i startup my Airspy R2 i see a really poor noise floor, have to stop /start a few times to get it where it should be. i don't see this on my SDRPlay rsp2 or rsp1a or my rtl-sdr dongles so i think this is airspy specific.
