Introduction: The Kenwood TS-590 and the Icom IC-7600 have a USB port which can be used transfer the audio signals to and from the radio. Other transceivers without a similar USB connection may need an external data interface device with built-in USB Sound Card such as the ZLP Electronics Data-Link, MiniProSC or Pro3 data interface from G4ZLP or the Tigertronics SignaLink USB for example. I have previously used a Tigertronics SignaLink USB with my Icom IC-706mk2g. I now use the excellent G4ZLP Data-Link with my Yaesu FT-891 (see my separate post for those settings)

Icom IC-706mk2g with Tigertronics SignaLink USB

Drivers: Firstly I installed the SignaLink USB as per the Tigertronics instruction manual. Installation depends upon the Operating System being used but everything is described in detail in the manual, on the Tigertronics website and downloadable manuals.

The laptop (Windows XP) shows the SignaLink as USB Audio Codec which can be accessed via the sound card settings and progams that require them, such as WSPR.

Kenwood TS-590 Set Up

Drivers: Firstly I installed the Kenwood virtual COM port drivers (Silicon Labs C_210x USB to URT Bridge) and the ARCP590 radio control program onto the old XP laptop - not strictly necessary for WSPR, but I thought it would be useful for other occasions.

In case it's helpful to anyone, here are the settings that I find work with my Yaesu FT-891 and a G4ZLP / ZLP Electronics Data-Link USB Sound Card. I would think that this will be much the same for other USB sound cards, such as the ZLP Mini-ProSC, ZLP Pro3 and SignaLink USB.

The main puzzle that I had was finding the correct RX and TX BFO settings. This is 1500Hz. Data Mode is OTHERS Data PTT will be DAKY and as the sound card is connected to the rear of the radio, Data In Select is REAR. Data BFO is USB (upper side band). Power as low as possible - 5 watts.
