WiNRADiO G3XX VHF/UHF Receiver

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.)
