OK, here is a schematic I promised you. The part coming off the microphone is simply an audio amp. At the bottom left is a Hartley VXO which enables me to shift the frequency above or below the 4MHz crystal. By doing this I was able to purchase a hand full of 4MHz crystals to do the whole job instead of ordering an expensive set of crystals for the lower sideband filter. The crystal filter is offset by 1500 Hz. The VXO worked out nicely because frequency stability is crucial to SSB. After I got my signal out of the modulator section (after Xtal filter) I mixed it up to the desired frequency using an up converter circuit configuration which was PLL controlled. Understand that when an SSB signal is being received, the receiver will re-insert a synthetic carrier back into the received SSB signal which now days will more than likely be some sort of digitally locked frequency control. So if you transmitted SSB signal drifts at all, it will be picked up on the receiver end and you are likely to get bitched at because the receiver operator will either have to re-adjust the frequency or if he has a separate BFO tuning control, he will need to re-zero beat your signal.
