@hamchallenge I must have heard the RTTY transmission a million times, often using it as an indicator for how long the skip is on 30m. Today I finally decoded it for the first time with fldigi, with the settings described by @ian in his blog (450Hz shift, 50 bd, 5N1). I was not patient enough to wait for an actual weather report, though. #HC20S #rtty #fldigi
