I see where I went wrong. I was thinking IC3 was the target of the new signal in my earlier post, I failed to realize that would only change TX. So, by attacking it at the tripler, the VCO output changes and that works for both TX and RX. I think I am getting it now.

Next bit of confusion I need cleared up. L19 is the VCO adjust. L22 is the tripler coil. You said you are injecting into L19. Did you mean L22?

On to the oscillator. Is there any schematic available? Which direction do you need it to go further?
