Hello, it happened during the Russian DX Contest last Saturday, from one second to another. No output. When I tune the display looks like this: http://dl1mgb.com/temp/k3_no_power.jpg Following conditions: - sending into a 50 ohm dummy load - no matter how many watts are set with PWR knob - Test mode off - TX INH off - all driver transistors working (three screw test) - no output power also on external watt meter - happens on all bands - happens with KPA set to "not inst" - knocking on housing doesn't change anything - when starting the antenna tuner, it says 5.0 watts, but no output on the external watt meter I am running out of ideas :-) 73s Chris DL1MGB
