After some tries with Jim GM4FVM IO85WU 632km finally tonight we had good decodes ! Time for a good Wiskey to celebrate. Your new XVTR does a real good job. Also 1 decode by GW4WND to night 659km My XVTR is not as frequency stable as thought. I have to correct it day to day 50-100Hz the local oscillator needs to be locked to the GPSDO too to be real stable.
