Sondeudp

Beschreibung von sondeudp

sondeudp ist Multikanal Wettersondemodulator. Als Audioquelle kann sowohl eine OSS Soundquelle (Soundkarte), RAW/WAV-Datei oder eine Audiopipe genutzt werden. Zusammen mit sdrtst, sondemod und einem USB SDR-Stick kann ein multipler Wettersonden-RX aufgebaut werden, der eine Vielzahl an Frequenzen gleichzeitig überwacht und mitschreibt. sondeudp dekodiert ausschließlich das HF-Signal und gibt alle Daten digital per UDP an einen Dekoder sondemod weiter. Eine Auswertung und Weiterverarbeitung dieser Daten findet innerhalb sondeudp nicht statt, man kann aber wichtige Daten mit -v in der Bildschirmausgabe anzeigen lassen.

Parameter Kurzbeschreibung
