This rather large model included a simple cassette player and an AM/FM stereo radio. It used a rather simpler type of mechanism than some of the previous models, yet still gave good performance. Chrome and metal tapes could be accommodated, but there was no Dolby noise reduction. Cue/review modes were included along with the normal fast forward and rewind. Text copyright © Walkman Central.

The radio, whose tuning scale was visible through the top of the cassette door, provided full coverage of the AM and FM wavebands and included a stereo decoder for FM. The FM antenna was formed by the headphone cable. As well as the tuning dial, two LED indicators were visible through the cassette door, which showed battery strength and the presence of an FM stereo signal. The minor controls were scattered all over the outside of the case, with the tape selector next to the winding keys, the tape/radio switch at the top next to the headphone socket and the waveband switch at the rear by the cassette door hinge.

Because of the WM-F9’s size, a standard belt clip would have not really proved adequate. Instead, a strap was provided that attached to the back, allowing the machine to hang vertically. The size meant that the WM-F9 was quickly outmoded, though its mechanism, in slightly modified form, went on to be used in the very popular WM-22. Text copyright © Walkman Central.
