I especially liked Dave's discussion of how and why .1 uF caps are used in the coupling and bypass network between the two chips.
Of course, the only thing I don't like about this rig is the, well, the chips. Can we persuade Dave to build the earlier discrete component version of this rig?
Be sure to read the many comments on Dave's post. Our friend Rogier comments on the beauty of it all. Edgardo LU1AR (the Argentine wizard with the gyrocopter) chimes in. And we see feedback from Eric Sears ZL2BMI himself. FB.
VIVA DSB!
