I was lucky not to blow my IRF's again, so I have done my first QSO's on normal CW. These QSO's are at the same time the first QSO's on normal CW from Czech republic. I have made QSO with OZ1KMR, OE5EEP/5, DK8KW, DL1SAN, DJ1RL. I used 4 x IRF540, on 24 Volts (droping perhaps somewhere around 20 Volts at the key-down state), with the current ranging around 18 Amps (the current changing with the antenna moving in wind...). Now I am building a new PSU, with which I could raise voltage in steps to as high as about 60 Volts to get higher output from PA. I want to be on the air following weekend too, but I can't promise. 73! Petr, OK1FIG
