(No, not Jokosher I’m at work, and there’s no Jokosher port for Windows. First, I went and got the mp3 of the message from Odeo and loaded it into Audacity. Well, I now know what it says, cos I wrote a program to decode it. mp3 format work well also, after converting to. Decoding Morse, the computer way Jeremy Keith’s been sent a Morse message and is wondering what it says. The signal can be displayed graphically for studying dashes and dots shapes, garbled characters and such. Information about audio frequency, words-per-minute rating, timing of inter-character spaces, etc can be printed too. wav format and prints out the Morse code message as cleartext. Let’s hope for a steady and fast recovery.Īnalyzing old recordings can be done anytime though! There is now a version 3.0.0 of the gerke-decoder program, where adaptivity against frequency drift and fading has been added. It is sad to hear that the Old Lady is not fit to sing out over the oceans this summer. I can make the decoding program available if there is interest. If the intention was to send at 15 WPM then the early transmission was an amazing accomplishment! With the SAQrx VFO set to 16500 Hz this suggests that the alternator would be running at 17190 Hz? Although there may be inaccuracies introduced along the way: The SAQrx program, the Audacity program for recording a WAV file, and the decoding program itself.īy counting inter-character spaces as 3 dot-time-units and inter-word spaces as 7, the average time per dot comes out as 79.93 ms, which gives a WPM of 1200/79.93 = 15.01. The audio frequency is reported as 690 Hz. = signed: world heritage grimeton radio station and the alexandergrimeton veteranradios vaenner association + = for qsl info please read our website: = + de saq saq saq = in view of the present pandemic covid-19 we want to pay tribute to all parties concerned within healthcare knowing their efforts will pay effect eventually.
The message then emerges quite cleanly:Ĭq cq cq de saq saq saq = this is grimeton radio/saq in a transmission using the alexanderson 200 kw alternator on 17.2 khz. It locks in on the audio frequency, applies mild clipping, adapts to fading, and uses a sliding window to discriminate tone from silence. My program does not decode an incoming stream on-the-fly, instead it analyses a complete WAV recording. So I ended up writing an audio decoding program myself. What is Morse Code Translator Morse Code Translator is a translator that lets anyone translate text to Morse code and decode Morse code to text easily. I also looked around for audio decoding software, but I didn’t find any that was easy to operate and producing good results. It was fun to work out the content of the early transmission, but it took me quite some number of listenings…
