Kenwood D700 Radio on ISS


A new  radio from the company Kenwood Company has arrived on the International Space Station.  The radio is a Kenwood  D700 Amateur Radio transceiver which arrived on August 31, 2003, via the Progress 12P Rocket.  This radio will support both Voice modes and Packet modes and includes a built-in modem for packet operations.  On December 8 2003 the Kenwood D700 was installed in the ISS module called the Zvezda Service Module and tested.  The ARISS team is working on a hardware usage schedule.

ISS-Ham Station, side view. IBM 760XD, Spare power supply, cable connections and the antenna switch, which will not be needed until the installation of the Glisser TV system in the future.
The Kenwood D700 remote display head is clearly visible, along with the radios microphone. Under the table you can see the active power supply on left and the D700 body on the right.  The DB9 cable coming out the back of the D700 should go to the PC. 4-Port Antenna switch.  This switch will be used at a later date.  All of the dust caps are still in place.   Antenna switch close-up.

If you look close you can see the names of each radio.

Kenwood D700 opened up for reprogramming.  The AIRSS team is having the EE-PROM custom programmed to support special features and will also prevent loss of settings if there is a long power failure. The EE-PROM burner connected to the D700.

The D700 was pre programmed with all channels needed for ARISS operations.  And transmitter power was limited to 25 watts to meet safety requirements.


The D700 is connected to a Wiener computer as part of Slow Scan TV evaluation test in Houston 2003. The D700 connected to the IBM 760.  Note the special data connecter going from the D700 to the blue VOX box, which is a PC audio converter and VOX control unit.
