Hi MF

PA is fixed now and current protection added. Running nominal 5A@12V at the= moment
Getting WSPR spots from DL in daylight

The mosfet was intact ! That explained why it was not showing short ci= rcuit
It was the drain copper track in the PCB that finally burned out prese= rving and protecting the fuse

Not a spot event, but the consequence of many hours running with some = antenna mismatch
and currents over 15A may be. An LM311 and thristor sensing the voltag= e from across the Amp meter
will trigger with this current values and bypass the PA for the rest o= f the night, if that happens again

PS: Upss! forgot to set my WSPR message for 1W ERP
