I also experience a shutdown after 45 seconds in TUNE on 50 Mhz into a 50 ohm dummy load. Output climbs from 100 watts to 106 watts and settles back to 100 watts before it suddenly drops to about 9 watts. There is a relay click as this sudden drop happens. It is repeatable. I am not aware of this happening on any other band. I am using 1.96 firmware.
