Finally Easy BITX is generating RF output!

Straight calculation is 4V into 50Ω = 0.32 W, provided, the RF probe is showing the accurate RF voltage! I am on the lookout for a 6V bulb with 50Ω resistance, that should be around 0.72W. If I get one, I can see the brightness of the bulb without having an impedance mismatch to IRF510 final MOSFET of Easy BITX. Still there is a snag there. Usually it is the hot resistance of 50Ω, resistance may be lower when it is cool and starting impedance presented to IRF510 may be a mismatch! That was the way I used to check output and tune final circuit when I had homebrewed a VU2VWN QRP way back in 1985. I did lose quite a few BD139s in the final of VU2VWN QRP.
