I have been considering making a simple zener diode rf noise source (either modulated or just noise) for antenna tuning. I have three (related) questions.
What is the proper place (and way) to inject the noise among the antenna line, tuner, and xcvr?
Then I set the rcvr to the desired frequency and twiddle the ATU for a null, right?
Anyone have a schematic? I am thinking of using the noise source from a noise bridge ckt that was in the '94 ARRL handbook.
I have seen some references for a 2020N (?) kit but the web links i find are dead.
