Description

Can connect and download from radio fine. However, when trying to upload to the radio I keep getting an error "Unexpected error communicating with the radio". I have tried using all 3 of my USB ports to no avail. Had just updated three other radios prior to this with no issue. Different radios of course but when trying to update this RT23 it failed.

This looks like a cable / driver / connector issue. Please refer to these Wiki articles:
CableGuide
CableGuide FTDI OEM Cables
RTSystemsCablesAndMavericks (if you're running MacOS)
In your case, it appears that the radio doesn't acknowledge anything written to it. I would suspect that there's an electrical contact problem.

Windows notes: If you are using a generic cable with a Prolific chip, you will very likely need to downgrade your driver to version 3.2.0.0.
It can be found at http://www.miklor.com/COM/UV_Drivers.php

MacOS notes: this OS is apparently very picky about USB to Serial cables. From what I heard, only (genuine) FTDI-based cables can be made work.
You must have the KK7DS Python runtime for Mac OSX installed.

Linux notes: Linux generally is quite good with USB to Serial converter drivers.
