一直以为15m波段的干扰是来自外部的，结果昨晚下台先关了电脑，我惊奇地发现干扰信号竟然没有了，原来干扰是电脑产生的，关了电脑就不能FT8，打开电脑有干扰😵😵😵

检查一下电源看看？🤔

先确认一下你是笔记本还是台式机笔记本：尝试使用电池看看干扰是否会改善如果改善了再看看你是不是pd充电器如果是尝试更换非pd充电器（pd充电器干扰会比开关电源稍微大一点）台式机：可能是你的电源质量比较低可以尝试更换电源看看

笔记本：换电脑适配器台式：换电源我家笔记本现在用的是pd供电

@"FengziLeo"#p98760 大概率是电源出来的

@"Moonlight"#p98762 台式机啊，品牌台式机，正在考虑排查是通过线路串进去的还是电磁泄露的

@"BG5GDP"#p98765 台式机，我怕换了电源还有干扰，打算先排查一下具体的来源是串的还是泄露的

@"BG7MGW"#p98774 台式机电源出来好几路线，不好加

@"BG9OWJ"#p98779 我直接在电源线220近电源的那个品字口加一个，自己另外拿一根电源线裁短做了插簧端子接电源滤波

@"BG7MGW"#p98780 现在还不知道干扰是从直流出来的还是交流出来的

I recently started using FT8 and discovered that the biggest source of interference was actually my own computer. How can I fix this?

BG9OWJ

I always thought the interference from the 15m band was coming from outside, but last night, before I turned off my computer, I was surprised to find that the interference signal had disappeared. It turns out that the interference was being generated by my own computer. When the computer is turned off, I can still use FT8, but when the computer is turned on, there is interference.😵😵😵

FengziLeo

Could you please check the power supply?🤔

BG9OWJ

FengziLeo Most likely, it's a power supply issue.

Moonlight

First, please confirm whether you are using a laptop or a desktop computer.

Laptop:
Try using a battery to see if it improves the interference.
If the problem persists, try using a different charger (a non-PD charger). Note that PD chargers can sometimes interfere with standard power supplies.

Desktop computer:
The problem might be due to a low-quality power supply. Try replacing it and see if that resolves the issue.

BG9OWJ

Moonlight Regarding desktop computers, specifically brand-name desktop computers, I'm considering whether the issue is caused by interference through the wiring or electromagnetic leakage.

BG5GDP

Laptop: Replacing the computer adapter
Type: Replace power supply
Currently, my laptop uses a PD (Power Delivery) charger.

BG9OWJ

BG5GDP Desktop computer. I'm worried that changing the power supply might introduce interference, so I plan to first investigate whether the issue is due to a connection or data leakage.

BG7MGW

Buy a power filter.

BG9OWJ

BG7MGW There are several power supply routes available for desktop computers, making it difficult to add one.

BG7MGW

BG9OWJ I directly added a new power cord near the power outlet (specifically, at the "L" shaped port of the 220V outlet) and then cut a separate power cord to create a plug-in terminal for connecting the power filter.

BG9OWJ

BG7MGW Currently, it's still unclear whether the interference is coming from DC or AC power.

Replacing the power supply...
