WM-F605

Though it was not obvious from the numbering, this model was effectively a WM-EX49 with the addition of a sophisticated digitally-tuned AM/FM stereo radio in the cassette lid. Despite the lack of a reference in the model name, the “EX head” was still fitted, something that was proudly proclaimed inside the cassette compartment. Text copyright © Walkman Central.

The bottom half of the machine, that is the side with the cassette mechanism in, was very similar indeed to the WM-EX49. The only difference of note was that the battery holder could only take a flat-type rechargeable cell and was now loaded from one corner of the case rather than through the back. This removed the need for a bulge at the rear, which was now completely flat. Text copyright © Walkman Central. Unauthorised reproduction prohibited.

The radio was very comprehensive. It could be tuned over the full AM and FM bands and could receive in stereo. Up to seven stations could be stored on each waveband, which were recalled by stepping through them in sequence using one of the two larger round buttons next to the display. The other button selected the radio and changed the waveband. Rather annoyingly, turning on the radio always selected the AM band first, something that could result in a loud noise in the headphones under certain conditions. The radio function was automatically cancelled if the tape transport was operated. To retain the radio memories while the main battery was being recharged a secondary power source was needed. In earlier models with digital tuning, such as the WM-F65, this had taken the form of a special capacitor which stored enough charge to retain the memory for about ten minutes whilst the battery was changed. This period of operation was clearly not enough for a model that was powered primarily from rechargeable batteries that took about four hours to charge so instead a CR2016 coin cell was fitted behind a small door in the cassette lid. This was capable of powering the memory for months, so the machine could even be stored with the main battery removed without loosing any settings. Text copyright © Walkman Central.

The WM-F605 was available in two versions, those with an “A” prefix (e.g. WM-AF605) had a sensitivity switch (local/DX) and those with a “B” prefix (e.g. WM-BF605) had a mono/stereo switch, both of which affected the FM radio only. Confusingly, some examples had both model numbers printed on them, so it was necessary to refer to the instruction manual to see which model one had. Text copyright © Walkman Central.
