Re: Calibration
OK. I don't know why, but the OpenGD77 firmware needs the calibration to me more accurate in the Tier2 version.
Often the factory calibration for the radio is not correct and causes problems.
Sometimes disabling the calibration and therefore using average settings, is actually better than the calibration data in the Flash memory setup in the factor.
PS. The CPS can now read and write the calibration, so you could try changing the master oscillator offset slightly, or possibly the I&Q values need to be increased or reduced slighly.
Often for the MD-380 the modulation level (I&Q) needs to be increased a little
