Thank you for taking part in our data decoding experiment. Our 50 second data message is in PSK-31 form, & is relatively easy to decode if you follow the guide below...


You may already be familiar with data signals & decoding, but if you are new to this we suggest you use the Essex Ham decoder which is available as a free download - click on the box below to go to the Essex Ham website page where you can read how to use the decoder & download the EssexPSK Application...  












Let us know how you get on & how you have received us - whether online or off-air.



PS - now you have decoded our message - why not carry on decoding ? - If you click on the 'Show Frequencies' box of the Essex Ham decoder you will see a list of HF frequencies used for PSK & RTTY amateur radio transmissions. We suggest you choose PSK-31 in the mode box & then enable your computer to hear the output from your receiver - normally placing an external microphone next to the receiver is sufficient - & click on one of the received streams. You will then see decoded text appear... Note - reception should be in USB - upper sideband mode.


Don't have an HF receiver ? - you can still use one of the tuneable online receivers. We often use the radio receiver at the University of Twente in the Netherlands to listen to the HF bands - click below...  








With our grateful thanks to Pete M0PSX & Charlie M0PZT for use of the Essex Ham decoder.    



To use the decoder with our data message, you will need to enable your computer to hear the 50 second message either from the off-air recording you have made or by listening again to our online mixcloud programme player (available on the World Service main page). If your recording is on a separate device, an external microphone connected to the computer is normally sufficient to feed to the decoder. You will see a vertical 'stream' appear in the blue 'waterfall' - click on the stream which will move the triangular cursor to the stream line. Hopefully - text will then appear in the box below !
