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.
