|Thank you Zack, that makes sense, and another thing is that when trying the display on my vintage signal generator that drifts quite a bit, the display is constantly changing.

|I am restoring a vintage Heathkit HR-20 and HX-20 and plan to convert the frequency display to digital. I would like to know if anyone has seen an aritcle in qst or any other publication on this subject. I thought I saw an article in qst a few years ago on this subject, but can not find it now.
Any help will be appreciated.
