RF noise signal for antenna tuning?	Reply
by KD5OPP on June 4, 2001	Mail this to a friend!
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. -73 de KD5OPP

Can get a kit from Ten Tec too. I bought one with a box for it. Have not yet built it.I think the modulation function is limited to AM-can't quite recall Bob
