Problem: I can hear the audio and tune the receiver, but the volume is
too low, even if I adjust the volume control to maximum.
Solution: Presuming the volume is set to the maximum level (31) in the
demodulator panel, you can adjust the volume also in the
sound card control panel, or on the amplified speakers you
are using. Also, if
SAGC function is turned off, turn it on by
clicking the Med button:
You can increase the volume when SAGC is on by adjusting
the
AGC reference level under Setup (excessive level will
cause distortion). If you prefer to keep SAGC off, you can
increase the volume under
Setup , by adjusting the Audio
gain level.
Problem: I can hear the audio and tune the receiver, but the spectrum
scope display is very sluggish, sometimes it even freezes.
Solution: Close all other simultaneously running programs to reduce the
burden on the CPU. This may indicate insufficient CPU
resources in your PC. Perhaps you have too many programs
running in the background?
Problem: I can hear the audio and tune the receiver, but the audio is
very noisy. The background noise level displayed on the
spectrum scope appears very high.
Solution: Make sure the Attenuator is switched off and the Preamp is
on. Check that your antenna is properly connected, the
connector is not loose and that the antenna cable is not
damaged. Does the noise floor drop significantly if you
disconnect the antenna? If so, then perhaps the antenna is
picking up too much ambient noise. Try to improve the
antenna, or move it further away from the PC. (
For additional
noise-defeating measures see also Appendix C – Dealing
With Interference .)
