I found the problem.
Advice on the screen when uploading says click "OK" then click "send" on
the FT-897D screen, then a sending progress bar appears.
However when downloading from CHIRP it doesn't have that instruction.
It just says click "receive" on the FT-897D screen.
I just repeated the first sequence I had done moments ago. That's where it
failed.
What I had to do was:
Click "receive" on the FT-897D screen.
Then click the dialog box "OK" on the computer screen.
Then screen changes to a "receiving" progress bar.
It will fail if you click the computer dialogue box "OK" before you click
"receive" on the FT-897D screen.
Maybe improved language would help here.
I knew it wasn't the cable connections if I could upload, but download
failed moments later with nothing changed with my setup.
