On medium and long wavebands an internal ferrite aerial is used. The extending aerial is used for FM and shortwaves. An external wire aerial can be attached using a 3.5mm jack plug as typically used on walkman type earphones. The sleeve could be connected to earth and the tip should be connected to the aerial wire. Inserting the jack will disconnect the internal ferrite aerial and silence the medium and long waves.

History of the Sony 7600 series radios with pictures and time line.
These little radios were donated to a charity shop. Colin Davies who checks electrical equipment donated says he gets large quantities of stuff that is perfectly OK, but which the shop can't sell because there is no demand for it. I made a small donation to the charity and paid for their postage.
