Thanks for posting this Richard, you've re sparked my interest in your rendition of the 49er vfo project.
I really like your code layout and the features that you added. I was able to tinker with your project
and got it to compile using the Arduino 1.8.12 IDE on ubuntu Linux. I then noticed some quirky
behavior and have added the code changes that you specified in the pdf. I was also a little puzzled
by the arduino output 13 keying the rig with +5V and decided that this output would drive an
opto-isolater that would key the rig. I made a call and was quickly picked up on RBN.
Now I'm working on reducing the BCI.
Thanks for putting your code out there for an interesting project.
