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. 630m WSPR map EU
