DX should be calculated longpath 19200km 
For us in the north wrongly the short-path distance is calculated in WSPR.


QTX at 630m burned out FET  IRF540  
This one lasted over 6 weeks 7x24 but the high winds made the load change too much.
Now replaced by IRL540 ( logic gate)
This type is more willing to oscillate.  Feritte bead over the gate but still at power up it oscillates for a few seconds.
It can be heard in the receiver a lot of running birdies and the drain current is not 0.
After a few seconds it stabilizes. Strange effect.
