CHIRP

I was about to close this as "these have been the labels on our menus for 15 years and a change now would be more confusing than not."

However, I realize that for 14.9 of those years they were "Download from radio" and "Upload to radio" and only with CHIRP-next did they change to the more terse and now more vague single words, unintentionally.

I'll ask for @Jim Unroe to opine here as he deals a lot with the users.

I know I've heard people confuse the meaning of download and upload even when they had "to/from radio" but it never seemed like a majority of people so I never gave it much thought. Perhaps "Read from radio" and "Write to radio" would be better.
