    PSK31 software will output audio to the PC's soundcard to send a transmission, however a mechanism must exits for keying the radio to transmit an RF signal, as well as link the audio tone to the radio's audio input. Therefore some form of soundcard interface may be used.

PSK31 Frequencies

    https://www.podxs070.com/frequently-asked-questions/psk31-frequencies
    Back in the early days of PSK31, the suggested operating frequencies all ended in ".150 kHz". This was at a time when tuning was done using the transceiver. Now that all PSK software is "click and tune", this level of detail is unnecessary. In fact, you only need to set your transceiver "near" the above frequencies, where "near" is defined as ...

    option, install it in the transmit audio input to your transceiver anyway. If you elect to use this capacitor, BE SURE to install it with the 'PLUS (+) lead towards the microphone inputor the transceiver audio input. The remaining lead connects toward the (RED) isolation (PSK31 Tx audio out) transformer lead.

    The circuit below shows the method I used which isolates the Sound Card Line In and Line Out from the Radio using a couple of Radio Shack transformers, and a 2N2222 transistor to switch the PTT radio line triggered by the RTS line of the computer Com Port. All audio levels are equalized when running either the computer, the SSTV program or PSK31.

Sound of RTTY and PSK Signals - QRZ Forums

    KC0W, Sep 13, 2009 #3 K4AX XML Subscriber QRZ Page PSK31 is only 31hz wide, and it almost sounds like a single tone. RTTY have two tones, usually 170hz wide, and has a distinct sound because of it. If you have a digital modes program with a waterfall, it is easy to see what they look like and you do not even need to listen to them.
