VXO BOARD - 17 meter DSB RIG @ CU2JL
I started out thinking that I could just use the same JFET VXO circuit that I'd used in my 20 meter superhet receiver. Wrong! In that circuit, the VXO was feeding the very high impedance gate of a dual gate 40673 MOSFET. In the DSB rig, it would be feeding the 50 ohm LO port of the balanced modulator. So I used a source follower and RF amplifier circuit from one of W1FB's books to get the VXO output up to the needed level.
I ran out of space on the original board, so I just built the amplifier on the inside back wall of the VXO's enclosure!
