Hi Mike
BTW, going to wind the toroids for my 30m kit tonight and it'll be done
then. The rest of the board is soldered and clean now. Also have to
build a low power wattmeter so I can have a reasonable measurement of
the power output.
Good luck. Don't forget: the wire thickness is a bit too thick and so winding 35 turns on the inductor that is in series with the crystal is a bit difficult. In my build of the kit, I wound only 27 turns and it still worked perfectly so don't worry too much about it, that inductor is non-critical.
If you have a 50-ohm dummy load (two 1/4-watt 100-ohm resistors in parallel would do fine) and can view the waveform across it on an oscilloscope, you will find you can measure these low output powers very accurately. 6.3V peak-to-peak corresponds to 99mW.
