Even I think that attempting to use 7400 NAND gates as linear devices is a bad idea.
As I recall, the author of the article agreed.
But a cool project regardless, rather eye-opening to see that it sort of worked.

I was going to build an rtx for 7MHz using 7400 N AND gates but having no test equipments except a good scope I could not experiment much. Discussing with some friends we came to the ending expecting high noise figures from such components. I used them as mixer for VFOs.
