  • Help transmitting PSK31

    I'm new to digital modes. I installed DigiPan 2.0 and have lurked in on
    several QSOs.

    I have a mic from the computer on top of my Yaesu FT-990, so that's the
    input to DigiPan. When I click DigiPan's T/R button, I can type a message
    into DigiPan, and hear the message come out of my computer speakers. Do I simply set my mic near the speakers, key up, and then click the T/R button?

    DigiPan's help says:

    "When you are transmitting, and not typing or sending text, the Transmit
    Volume should be increased until the RF output power of the transceiver just stops increasing, and then reduced until the power falls to half of the
    amount when it just stopped increasing. This should result in maximum undistorted output power under PSK31 operation."

    I increase the volume of my computer speakers until the RF power stops increasing, then I decrease the volume to half of that? Am I reading this right?

    Thanks much and catch you on 14.070 mode PSK31.

    i've never tried it your way; generally most people use an interface
    like the 'rigblaster' or similar interface. this couples the output of
    your soundcard to the audio input of your rig, and allows you to use
    the microphone as well. since i've never tried your way, i won't say
    it can't work...but it probably won't. too hard to get the audio
    levels right.
