DSB BOARD - 17 METER TRANSMITTER @ CU2JL
This simple circuit has appeared in several of W1FB's books. It was also featured in the February 1997 issue of CQ magazine. Doug DeMaw's was designed for 40 meters but I built mine for 17. I found that was getting significantly lower power out from mine -- I figured this is the result of lower amp gain at the higher freq. So I just built two 2N2222 RF amps on the board instead of one. Also, I didn't have the right value pot, so I just put an appropriate value resistor in parallel with the pot that I had. Worked fine.
