Is it your IRF510 PA? The T106-2 will be good for 200W in a LPF, the IRF510 maybe for 20W@12V :-) Looking forward to see your signal on my grabbers and in QSO mode, maybe next season :-) Good luck and fun! I enjoy your experiments. 73, Stefan/DK7FC Am 29.01.2011 20:18, schrieb Roger Lapthorn: > This is the QRP transverter so far (see image).
