Ben WRAX296It is worth the call to see what they have to say, particularly if radio is new.I have done some experiments on my end and currently learning towards an internally maladjusted AGC circuit in the outbound audio path. Initial audio levels seems good when first transmitting but it includes gross audio clipping (distortion), then the audio drops down to almost nothing and then ramps back up to ‘normal’, but includes some degree of clipping. In my over-the-air experiments with some seasoned operators it has been reported that the problem seems to mostly go away when the mic is held 6-10 inches away from the mouth. This is not generally good in a mobile situation. However, if get acceptable results at this distance, I may modify the mic my mic to pad its audio down so that I can use the mic closer to the mouth to cut down on the background noise.One local swears he has read some posts overseas about folks reporting this same problem, but while using the KG-UV980 (same electronics as the KG-1000G). Reportedly at least one of them managed to get their hands on some kind of service software package which had allowed them to disable that circuit and that it solved their problem. I have looked far and wide with no luck, so I suspect he may be thinking of a different radio model. In any regards, he promised to try and find the original thread and send me a link. We will see. I will keep you in mind if such software is actually found.MichaelWRHS965KE8PLM Quote Link to comment Share on other sites More sharing options...

0 StepUp2TheMyke Posted April 9, 2022 Report Share Posted April 9, 2022 I have the same modulation problem especially on the lower frequencies. While poking around I decided to get rid of that noisy fan.... Quote Link to comment Share on other sites More sharing options...
0 wqpn591 Posted April 14, 2022 Report Share Posted April 14, 2022 try turning the mic gain setting off. Had similar issue with a Radioddity and that fixed it. Quote Link to comment Share on other sites More sharing options...
0 donniefitz2 Posted January 4 Report Share Posted January 4 I realize this thread is pretty old, but has anyone found a solution to this problem? Everyone I know with a KG-1000G has the same audio rollercoaster problem. It starts out loud, ramps down, then back up within seconds. It's really irritating and there seems to be no way to fix it in the settings (nor with multiple returns under warranty). For a radio priced like a Yaesu, this thing has been disappointing. Also, the fan sounds like a Vitamix full of ice. I could get past its other issues if my audio didn't have this ramp up, down, up problem.

0 StepUp2TheMyke Posted March 11 Report Share Posted March 11 I have found a particular issue with this radio. It seems if you leave the lower channels with high power programmed in memory, the radio will automatically switch to low to be FCC compliant. The time it takes the radio to automatically switch to low power is the cause of the delayed audio output on transmit. It seems to affect other channels if left with high power programming in the lower channels. Once again poor firmware problems. Quote Link to comment Share on other sites More sharing options...

0 OffRoaderX Posted March 11 Report Share Posted March 11 The audio problem is caused by the Automatic Gain Control (AGC) being a bit aggressive. Everyone I know that has this issue is able to improve it by not holding the mic so close to their mouth and holding it at a slight angle from their mouth (instead of directly in front of their mouth) so they aren't "popping" their Ps and Ts.

This is not the case with any of the radios I've dealt with having the audio issue discussed in this thread. FYI: posting the same incorrect information multiple times wont make the information any less wrong. gortex2, kerstuff and wrci350 2 1 Quote Link to comment Share on other sites More sharing options...
