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.

Yes, it does make sense. Serial connections use *two* independent data lines (plus ground): RX and TX.
If you trigger your radio to give you all its data (download contents), then the radio will use its TX line to feed the RX of the USB cable. Chirp reads it from there. The radio's RX line is not in use for this task.
But when you try to upload data, then the TX line of your cable tries to feed into the RX line of your radio. It attempts to send a command causing the radio to accept data. There's a disconnect. Nothing arriving at the radio, which otherwise would send an acknowledgement back.
Check your cable and connector.

Bernhard,
This is a problem only for writing, not reading from radio.
Doesn't make sense to me.

Hi DR,
This looks like a cable / driver / connector issue. Please refer to these Wiki articles: CableGuide CableGuide FTDI OEM Cables
*Linux notes:* Linux generally is quite good with USB to Serial converter drivers. The most likely cause for grief is a connector which doesn't provide good electrical contact. In your case, it looks like serial TX is not making contact. Check your cable and connector.
