Geocache Description:

Zürich Kreis 6: Ober- und Unterstrass


Im Kreis 6 (Ober- und Unterstrass) gibts ein paar Pärke und begrünte Ecken, die ganz nett sind. Einer davon ist der Beckenhof (obige Koordinaten, wo der Cache nicht ist).

Dieses Mal ist Hören gefragt. Höre dir diese Zweiton-«Musik» genau an und ziehe daraus die Koordinaten.

Hinweis: Das folgende ist ein externes File. Der Eigentümer bestätigt, dass diese Datei kein Problem bereitet. Groundspeak bzw. der Reviewer hat diese Daten nicht geprüft. Download erfolgt also auf eigenes Risiko.

Hier ist die MP3-Datei: von Server 1 oder Server 2 (falls Server 1 wieder mal nicht erreichbar sein sollte).

PS: Code für Bonuscache merken = die N-Tauendstelminuten (also 3 Stellen). Mehr zum Bonuscache.

Bitte Cache vorsichtig behandeln. Nimm deine ganze Cacherausrüstung mit. Und bitte keine verräterischen Logs jeglicher Art! Es wird noch keine Hilfe geboten.

Diese Tabelle hilft dir nicht weiter, ist aber nett für interessierte Personen.
This table does not help you, but it s nice for interested persons.

There are some nice parks or small green areas in Zurich s district 6 (Oberstrass and Unterstrass). A nice one is the Beckenhof (coordinates above where the cache is not located).

To solve this mystery, you have to listen carefully to the two-tone music in order to find out the coordinates.

Alert: You are about to download a file. As the cache owner, I represent that this file is safe. The files needed to complete this geocache have not been checked by Groundspeak or by the geocache reviewer for possible malicious content. You are downloading this file at your own risk.

Here is the MP3 file: on server 1 or server 2 (in case server 1 is down again).

PS: Note the thousandth minutes of the final N coordinate for the bonus cache (3 digits). Please carefully treat the cache. Please take along your whole caching gear. No spoiling logs please! There is no help given yet by the owner.
