Thanks so much Jack. I've often needed that info for other projects! I printed it out fo keep.
However, I was referring to Ian's precompiled hex files I couldn't find, because I was having trouble compiling/uploading them from the Arduino program.
The hex loader program worked fine on the one I found.
It turned out to be the nano bootloader problem!? ?I swear I had used the top option not the old bootloader option on previous occasions and now only the old one works.
At any rate, I'm now thoroughly enjoying Ian's work. The 20x4 I2c display works fine.
Thanks again.

P.S. I have some spare parts left over from your nice QST XCVR project If anyone is interested. I can do inventory if needed.
