This site provides schematics of various radio projects that you can experiment yourself.
The figure shows super simple CW transmitter with bare minimum components
Ok
What does the 100uH inductor do? Would this circuit work with other crystals?
This transmitter will work with a 80m, 40m and a 20m crystal. Just adjust variable cap before antenna to tune for lowest swr. Of course type of antenna will make a big difference. I built this and used on 40m with a 33 ft long wire and tuner.
