Receiving and Transmitting PSK31 With Your Macintosh
IntroductionUsing MultiMode, you can send and receive PSK31 with your Macintosh. After connecting your Mac to your radio (see our interfacing notes for details on this), fire up your copy of MultiMode and set it for PSK31 mode.
Next, tune in a station sending PSK31. For example, on 20 meters, 14070 is the most active PSK31 frequency, tune it in any time the band is open, and you are almost sure to hear several PSK31 stations active. Set your receiver mode for USB.
When properly tuned in, decoded text will start to appear in the text area of the MultiMode window.
For transmitting PSK31, your Mac produces audio as set by the center frequency. When you start transmit mode, using cmd-T, MultiMode will begin playing the PSK31 audio. You can feed this into your transceiver's microphone input to transmit PSK31. It's that easy!
