The first Sony multi-band receiver. Receives 23 bands in all, including two FM bands, 19 shortwave bands, and midrange bands. Three large tuning dials dominate the controls, which include several levers and a film transfer dial with 100 kHz readout added for the first time. In appearance, it appeals to a professional's eye. The radio lives up to its name of "World Zone 23" by supporting outstanding reception for broadcasts from all over the world, and has been enjoyed by many radio enthusiasts.
