  1. What does the 100uH inductor do? Would this circuit work with other crystals?

  2. 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.
