Hi All,
I have been working on increasing the power out on 40 meters.? Original I had just under 3 Watts using the QRP Labs dummy load.? I first took two turns off of L510 and power went up slightly.? I ended up taking 4 turns off of L513.? I'm now up to 3.75 Watts.? I felt I might get more power if I took more turns off of L513 but I'm starting to get gun shy.? I've included an LPF plot at the final configuration.? Should I leave it alone or try to go for 5 Watts?
?
From the plot it looks like I may have shifted up the cutoff frequency quite a bit.
