Re: NOISE GENERATOR for the HOME BREWERS

David,
I am aware that you stated Ham Radio.
I've searched their archives as well as their cumulative indexes with no results. There are 269 Ham Radio editions in the index, from Feb 1968 to June 1990.?
I then did a generic search using Ham Radio Magazine as the search topic, which came back with the QST articles.
Richard?
It was in HAM RADIO, not QST.? I noted that in the email.? Try the archives of HAM RADIO magazine.

There are two noise source articles in QST.
January 1977 pp 22 "Gated Noise Source"??
May 1994 pp37 "Calibrated Noise Source"
Is the January 1977 the article you are referring to?
Regards, Richard?
The best ever ham radio publication, Ham Radio, once published a relatively simple project:? a "Gated Noise Source".? I built and extensively used one from MF, HF, VHF, UHF, and through 1296.? Search the Ham Radio archives and you'll locate it.? If you don't want the "gating" function, its even simpler.
HINT:? Low voltage Zeners biassed just as the break into conduction produce the most noise.? You can select them using an o'scope of sufficient BW.? Or, better yet, your TinySA!? Be sure to decouple the bias from the SA.
