Kenwood TS850 CAT Interface

Yesterday I got a FTDI (UART to USB) CAT interface. Delivered from UK.

Cable 001

This is a USB operation utilising the common FTDI Chipset. Search ebay for sjgwfilliam or goto Kenwood Interface Shop.

Little bit to do to get the device to work on the Mac as Apple have a driver in 10.x which you need to disable and install the genuine FTDI drivers.

Disable the AppleUSBFTDI.kext extension;

  • sudo mv /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBFTDI.kext AppleUSBFTDI.disabled

Then downloaded and installed the Mac OX 64 bit FTDI Drivers;

Follow the installation directions.

Finally reboot.

Verify the device is detected and driver loaded;

Config 001

The Apple drive has been removed and the FTDI drives added,so now configure the application.

I’m using MacLoggerDX (5.59b4) on MacOS:10.10. One panel to setup. Verify the device name;

Config 002

The RS232 settings for the Kenwood are 4800 Baud, 1 Stop bit and no DTR or RTS. Here are working settings;


Companied with having SOTAWatch in the the DX Cluster list the radio will now autotune to the spots and have the activators details up. Not sure if that’s the activators pet dog or sheep.
