==Summary==
WZYN or Zynden's Radio Z International (formerly known as Zynden's Random Music's) Is a AM, FM and DRM station that Broadcasts on 7.38 (no longer active), 4.78, 4.48 (Japan) and 96.2 MHZ. WZYN Features Radiogram (Ex. MFSK 64 and 32) and DRM with Journaline and Slideshow Services.

== 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 C, 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.

On '''September 1st''', WZYN announced the upcoming new Shortwave station, which would be part of the Latin region. Following that same day, they are launching an exclusive WZYN satellite HD Radio on 1.49 Ghz as a experimental station.

Later on '''September 2nd,''' WZYN added MOT Website service to DRM. Considering the fact that the transmitter isn't functioning properly.

'''WZYN recently completed several major broadcasting upgrades throughout September 2026.''' On September 4, the station finalized its 24/7 FM broadcast on '''96.2 MHz'''. Following this, operators extended the Digital Radio Mondiale (DRM) broadcast schedule on September 27 to run from '''03:00 to 10:30 UTC''' to better serve corresponding time zones. Finally, on September 29, WZYN Changed its DRM playback by switching from xHE-AAC to HE-AAC v2 P-Stereo while simultaneously merging the '''Journaline''' text service into the primary audio stream.

Later on October 24th, WZYN Change the DRM Kbps rate heavily.

On November 5th WZYN Decided to test out DRM+ as a little experiment. Before concluding.

== Shortwave Radiogram ==
Hosted by Dr. Kim Andrew Elliott, Shortwave Radiogram (formerly known as '''VOA Radiogram''') broadcasts on a regular schedule every '''Sunday at 14:30 UTC''' and '''Thursday at 23:30 UTC'''. The program transmits digital text and images over analog shortwave signals using the following structured format:

* '''MFSK32:''' Program Preview
* '''MFSK32:''' Article 1 (May or may not include an embedded photograph)
* '''MFSK64:''' Article 2 (Mostly includes an embedded photograph)
* '''MFSK64:''' "This Week's Images" gallery
* '''MFSK32:''' Closing Announcements

Shortwave Radiogram also has 2 other participating Stations:

'''Like The Mighty KBC and Pop Shop Radio, WZYN also has its own radiogram''' (WZYN/Zynden's Radiogram) that only transmits occasionally during special events. Examples include '''tributes, historical features, celebrity birthdays, and anniversaries'''.

== Trivia ==
Did you know that WZYN USA has 4 Radio towers in different directions?

WZYN was once Jammed by Iranian Bubble Jammer.[https://mp3tourl.com/audio/1788226771064-29175489-7cd9-4fb3-b842-3b370ee56a39.mp3 Jammed on 7.38 Mhz]

Before WZYN changed frequencies, it's final music was called "Final Countdown".[https://mp3tourl.com/audio/1788228296932-d7c5fa32-ce28-4d0d-8fea-f8f2fb439e52.mp3 Listen to it here]
