请问下g90s 在ft8发射的时候 ALC100正常吗？应该怎么控制ALC比较好，我如果把手机给电台输出音量调小，功率就掉下来了，alc大约还有60左右，我如何操作让发射功率上去，然后让ALC低于100（群里大佬反馈alc100 不是好状态，代表电台的自动电平控制已经全力介入，正在强行压缩音频）。上述状态出现的时候我已把MIC GAIN调到0了，alc还是高。或者发射功率掉下来。

@"BI4OAE"#p100392 驻波指标正常，只管射就是

看看发射频谱没问题就可以吧。而且每个波段的ALC不同。

我G90S。ALC一般被我控制在20以下，且功率能正常出。

@"BG4QBF"#p100427 能给指点下设置思路吗？主要调整哪些地方？谢谢

@"BI4OAE"#p100392 建议找一下不同版本的G90说明书，对于G90来说，ALC100，代表没介入，ALC0，才代表全力介入，和你说的相反。

在我的思维里，ALC控制在20以下，代表20-100之间，数越大，自动功率控制模块发力越小。

说明书原文：“外部输入信号强度要在 ALC 控制范围以内（ALC 值：30～100），避免输入过载。”

1.81固件下，使用数字模式通联，ALC＜50以保证良好线性，实际使用不必关注具体是多少最好，在发射时缓慢调整电脑输出音量，当显示功率达到设置功率，这时就是最佳状态，也都会在50以下。1.81之前固件不适用这种方式

我去看了一眼Rev.05中文版的说明书，说明书第31页 > 外部输入信号强度要在 ALC 控制范围以内(ALC 值:30 ~ 100),避免输入过载。

What is the normal ALC state when transmitting with G90S using FT8?

BI4OAE

Is the ALC100 functioning normally when transmitting with the G90S on FT8?
What's the best way to control ALC? When I reduce the output volume from my phone to the radio, the power decreases. The ALC is around 60. How can I operate it to increase the transmission power and then bring the ALC below 100 (as suggested by others in the group, an ALC of 100 indicates that the radio's automatic level control is fully engaged and forcefully compressing the audio)?
When these conditions occurred, I had already set the MIC GAIN to 0, but the ALC was still high, or the transmit power had decreased.

BI8FRF

BI4OAE The dwell time indicator is normal; just aim and shoot.

BG2LCG

BI4OAE I recommend looking at different versions of the G90 manual. For the G90, ALC100 indicates no intervention, while ALC0 indicates full intervention. This is opposite to what you said.

BH5EIJ

BI8FRF I agree, hahaha, that's all there is to it.

bi4jcp

If the transmit spectrum looks okay, that's good. Also, the ALC (Automatic Level Control) settings are different for each frequency band.

BG4QBF

I am using a G90S. I typically keep the ALC at 20 or below, and the power output is normal.

BI4OAE

BG4QBF Could you please provide some guidance on how to configure it? What are the main areas that need adjustment? Thank you.

BI4KSR

BG2LCG Because XieGu's ALC and Icom's ALC are opposite.😆

BG2LCG

In my understanding, an ALC value of 20 or below indicates a range between 20 and 100. The higher the number, the smaller the power output from the automatic power control module.

BG2LCG

Original instruction: "The strength of the external input signal must be within the ALC control range (ALC value: 30-100) to avoid overloads."

BI1SFC

With firmware version 1.81, using the digital mode, ALC < 50 to ensure good linearity. In actual use, it is not necessary to focus on the specific value; instead, slowly adjust the computer's output volume during transmission. When the displayed power reaches the set power, this is the optimal state, and the ALC will also be below 50. This method does not apply to firmware versions prior to 1.81.

BG4QBF

I glanced at the Chinese version of the manual, specifically page 31.

The strength of external input signals must be within the control range of the ALC (ALC values: 30 ~ 100) to avoid overloading.

BA4QBK

I usually do it at 30.
