    Hi
    I have a Sony HCD-SPZ90DB and I can't find the FM/DAB Aerial wire, the unit has a 3 pin receptable, seen some on fleabay, but they are only using one of the pins !, could I make one , getting a 3 pin plug, are all the 3 pins used ?.

    cheers
    Spike

    Looking at the circuit diagram in the manual, the middle pin 2 is the antenna ground, and pin 1 is the antenna signal. Pin 3 is unconnected.

    Should be easy to make up an indoor antenna for good signal areas.
