I've resisted selling this until now, but I need to sell some of my existing kit to finance a new HF radio so with some reservations it's up for sale :-)

I've owned this AOR SDU-5500 from new and it's in great condition and a great example of the quality kit made by AOR in this period.
No scratches dents or anything like that and it comes with the original box (not in the photos as it's still in the loft), and the original accessories, manual, 10.7 MHz RF cable, 9-pin serial cable, and the power cable.

The SDU-5500 works with the AOR 5000 receivers and the AOR 3000A if it's had the 10.7 MHz IF output mod, several Icom receivers or any other radio with a 10.7MHz IF output.

It's easy to drive and the display is nice and clear, great for seeing activity on the bands.
I've included some technical information from the web below.

  • Menu driven operation
    All facilities are within easy access through each dedicated function key and on-screen menu.

  • Full inter-connection with the AR5000
    The AR5000 can be operated from the SDU5500 enabling selection of centre frequency, receive mode, etc. Any frequency spotted and monitored by the SDU5500 can be received by the AR5000 straight away.

  • Full inter-connection with other AOR & Icom equipment
    Support on menu for AR3000A, AR5000, IC-R7100, IC-R9000, IC-R8500

  • Direct reading of the receiving frequency and input level
    By placing the cursor on any spot frequency you can read its frequency and input level on screen. When connected with the AR5000 the SDU5500 virtually works as a spectrum analyser over 10kHz to 2600MHz range as the centre frequency always becomes the receive frequency.

  • Wide spectrum coverage
    The SDU5500 covers a maximum of +/-5MHz spread against the input frequency.

  • Dual frequency resolution
    Selectable, either 5kHz or 30kHz resolution.

  • Wide input range
    -10dBm to -90dBm by using two selectable gain settings.

  • Highly accurate frequency management
    Through the DDS controlled local oscillator circuit. 

  • Wide variety of displays
    Graphical display and statistical analysis.

  • Remote control via PC
    All keyboard operations of the SDU5500 can be mimicked by PC.
