Thanks Bob for the sugestion, I have been looking for a means to pull the oscillator that I use for QRS and DFCW. The cap. in series with the xtal gives me coarse adjustment and now the emitter resistance change enables a "fine tune". I am able to achieve 0.5hz shift in the final 137 khz output. although I need to reduce the emitter resistance by 50% to achieve this. 73 Laurie.
