Just a small update.
I have backed up my memory card to a USB stick with the built in app!
Software update went well with the two steps in the help page.
I built a keyer cable for the system and re-discovered that you have to know how to use your radio first,....
(If break-in is not on the IC-7300 is a really expensive side tone generator!)
I have started messing with three different remote access methods. I will write that up separately.
