Hi,

My K3 died today, somehow. The radio works fine on receive and appears 
to transmit just there is no power indication on my external meter or on 
the front panel when pressing TUNE. There is ALC indication but no power 
out indication.The only thing I did different was to switch off the 
supply before the radio, something I normally never do. Having noted 
others having issues with that I reloaded the firmware. Still no output. 
Starting to think that somehow the PA is fried or possibly the driver as 
there is nothing from the 10 watt PA either. Tried turning the power 
down and putting the KPA3 into bypass. Still no power output. Not sure 
what else to try before I tear into it. Was going great, worked 3B7A on 
3 bands today no problem.

Suggestions appreciated.

Thanks
Martin, HS0ZED
