本人纯萌新，完全不会焊板子，所以请大佬们尽量推荐某宝某夕夕能直接买到的东西😂 最近在尝试接收SSTV图像，因为家里信号一般，室外会好些但环境噪音很嘈杂，再加上本人比较社恐，不敢手台外放录音😭 所以想尝试能不能用手机直接内录手台声音，然后拿回家慢慢解析。

搜搜3.5mm纯音频采集卡，有这东西。

k型连接器转3.5? 侧面两个圆孔2.5应该是输出，3.5是输入

我之前用k转3.5接录音笔录的没有额外杂音

@"yuhjnmwe"#p82254 好的谢谢~我去找找看

@"BG7PUW"#p82259 谢谢，不过对于我来说还是有点难了，我先试试简单的，搞不定再用这个吧😂

@"BH5UNT"#p82266 这个的话，是不是还需要一个3.5转type C 公转公的线才能连到手机上

Could you please advise on how to record audio internally using the UVK6?

BD1BUK

I'm a complete beginner and have no experience soldering, so I would really appreciate it if you could recommend some items that I can easily purchase on Taobao or other platforms like Xianyu.😂

I've recently been trying to receive SSTV images, but the signal quality at home is generally poor. While it might be better outdoors, the surrounding noise and my own social anxiety make it difficult to operate a receiver outside. I also don't feel comfortable using an external microphone.😭

So, I was wondering if it's possible to directly record audio from a radio using my phone and then analyze it at home later.

yuhjnmwe

Search for a 3.5mm pure audio acquisition card; I have one of these.

BD1BUK

yuhjnmwe Thank you._{I'll look around.}

DIY phone internal recording and external microphone input cable

BD1BUK

BG7PUW Thank you, but it's still a bit difficult for me. I'll try the simpler method first, and if that doesn't work, then I'll use this one.😂

How to convert a K-type connector to a 3.5mm connector?
The two round holes on the side, with diameters of 2.5 and 3.5, are likely for output and input respectively.

BD1BUK

BG4QBF Okay, thank you.

BH5UNT

When buying this type, be careful about the different types of K heads inside.

BD1BUK

BH5UNT In that case, would I also need a 3.5mm to USB-C adapter to connect it to my phone?

BG9JXB

Previously, I used a K-connector to connect the microphone and recorder, and there was no additional noise.

BD1BUK

BG9JXB Received thank you.

BH5UNT

BD1BUK Oh? Does your phone not have a 3.5mm jack...? Then you'll need to buy another USB Type-C to 4-pin 3.5mm connector cable. This is commonly called a "Type-C recording cable."

BD1BUK

BH5UNT Unfortunately, with current mobile phones, there's only the Type-C port available.😂 If connected this way, would I then be completely unable to hear the radio's audio during recording?

BI1UDG-711

2. 5mm audio jack, which can be used to connect a 3.5mm audio jack or a C-type connector to your recording equipment.

BD1BUK

BI1UDG-711 Actually, these two ports can be used separately.😂

BI1UDG-711

BD1BUK Must be able to

BI1UDG-711

BD1BUK I connected a 3.5mm audio jack to my recorder.

BD1BUK

BI1UDG-711 Received thank you.

troilus

Also, get a 1.2m audio cable, otherwise you won't be able to adjust the device based on the receiving effect.

BD1BUK

troilus Oh, right, thanks for reminding me. I almost forgot about this. So, generally, where is the best place to insert it – port 1 or port 2?😂

troilus

BD1BUK 2.5mm输出后就分开，因为内录手机那根线有电阻需要让手机识成麦克风的

troilus

BD1BUK 今天看到还有个方案，用耳返app，手机收到的音频返给耳机，这种没尝试过
