Problem: I can tune the receiver and see the signal peaks in the
spectrum scope, but I can’t hear any sound at all.
Solution: Check that your speaker or headphone is connected to the
speaker output of the sound card. Set the volume to medium (say 15), the
squelch to the lowest value (-130 dBm) or defeat the squelch by clicking on
the Def button. Make sure the Mute button in the demodulator panel is
released, too, and the speaker output of the sound card is unmuted in the
sound card control panel.
Problem (G303i or G303e with serial interface option only): I can hear
the audio, but it is not a pleasant sound. There is an interfering high pitch
tone.
Solution: You need to mute the Line input in the sound card control
panel - see the panel on the next page. (What you are probably listening to
is the intermediate frequency signal mixed with the demodulated audio
signal.)
