History
Zynden's Random Music's started as a Pirate random music station (hence the name) on July 2, 2026. Its original frequency was 7.68 MHz AM, but it later moved to other frequencies, such as 7.45, 7.39, 7.12, and 7.10 MHz. Finally, it settled at 7.38 MHz. At the time, its only focus was to blast music for people to enjoy.
Later, on July 20, Zynden's Random Music changed its name to Zynden's Radio 7.38 to reflect that the station now broadcasted on 7.38 MHz exclusively. At this point, the station no longer just blasted music; it also began sending images via MFSK, DRM (EasyPal), SSTV, and KG-STV. On July 22, the station became a official licenced station then renamed itself one final time (potentially) to Zynden's Radio Z or WZYN, which later became its most recognizable name.
On August 5, WZYN participated in Shortwave Radiogram. On August 22, WZYN began DRM transmissions as an experimental station using Robustness mode D, which would later become permanent and use Robustness mode A instead. Then, on August 30, WZYN shut down its 7.38 MHz frequency to move to 4.78 Mhz. Following that day, WZYN announced the launch of a sister station, WZYN Japan Featuring Hatsune Miku.
