Controlling the Kenwood TS-450SAT through a Transceiver Interface

The Kenwood TS-450SAT (no matter if with a Antenna Tuner or not, so also the TS-450S variant) both have a serial connector. It is located at the left side of the transceiver.

I decided to purchase the BX-120 interface from the German HAM magazine "Funkamateur", because

• it is a USB device
• it is supported by Linux
• it has a galvanic separation between the TRX and the computer circuitry
• it can control audio and the serial data link plus the key in a single box
• it can be used with a great number of transceivers
• there's a good documentation that comes with it

In short, it fulfilled all my requirements.
