One possible substitute for a Spectrum Analyzer's "Tracking Generator" #ubitx

I got an email from a trusted friend this morning with some very interesting information for those who have spectrum analyzers that do not have tracking generators, or the new versions of inexpensive VNA's like Ashhar's "Antuino" or the NanoVNA which have sweep functions but I'm not sure exactly how they work in this respect.

Below is a link to a site that explains how to use a reasonably inexpensive wide band noise generator as a substitute for the tracking generator.  Short article that goes into enough detail to help you get started and the second link is to a possible source (eBay - there may be others as well) for the generator itself.  If the links don't work, cut and paste them into your browser's address window.

One possible source of the noise generator:

This info may help some of you with BFO alignment on your uBITX.
