I have come across this excellent resource for wringing the best audio out of (and into) the Kenwood TS-590S, and I wanted to share it.
I came into possession of a TE-590S at Dayton 2018 for the great price of $495 with the understanding that the USB port was not working. After playing with the radio since Dayton and after reading this article, I think my TS-590S is going back to Kenwood to get the USB port repaired.
Fair warning, to really get the best sound out of (and into) your TS-590S, you’ll need to connect a Windows computer running Kenwood’s free ARCP-590 software. As a bonus, I can’t wait to test out the Visual View feature shown below:
