要求145.8mhz，FM调频模式，是用的uvk6，频率145.8mhz，设置里调制模式选的FM，没有收到图像，是我的设置错误么？还是受要用收音机的FM调频

静躁要打到0，其次如果你没接八木的话要把手台与手机垂直放置（如下图，画的不好凑合看吧😭），再就是找个没遮挡的地方，其它好像也没什么了 [upl-image-preview url=https://storage.hamcq.cn/2024-11-11/1731364394-671178-screenshot-2024-11-12-06-32-45-428-commiuinotes-edit.jpg]

@"BG4JGB"#p40453 垂直么？我以为要跟着手机把手台对准卫星，这是什么原理

@"BG4JGB"#p40453 不应该平行吗

卫星追踪软件不一样吧，两个卫星追踪软件，一个是垂直，一个是平行，Look4sat是平行。

其他设置没问题，UVK6原天线的话，接受信号水平方向增益更好，所以你要把天线垂直卫星方向，即垂直于手机指向，昨晚在城区接受也没成功，应该是干扰太多。再就是想要抵消多普勒效应的话，需要算好频率，信号下来不会是在145.8MHz，我这边大概是145.796MHz。

手台的仰角是由国际空间站的仰角确定，不能单纯的水平或垂直。接收时手台应打开监听或将静噪等级调至为0 国际空间站的信号很强，原装天线接收完全没有问题。

静噪开0或者开监听，不用管手机啥的，记住原装天线【理论上天线侧面始终对着ISS】，但是不绝对，可能手动要旋转下，能收的

@"BI2WD"#p40454 之前我也是平行放置的，一点信号没收到，后来有人告诉我这么垂直着放，同样的位置接收效果就好很多

@"troilus"#p40471 好的，谢谢

Regarding receiving SSTV images from the ISS space station

BI1SFC

The theme of this SSTV event is "40 Years of Amateur Radio Participation in Human Spaceflight," and the event will last for one week. Participants can join in using the UV-K6 with RH775 pull-out antenna, and I received a perfect image today, which is the 5th out of a total of 12 images.

BG4JGB

BI1SFC I'd like to know if the UV-K6 can directly record audio into my phone using just a single data cable. The method of recording through my phone always picks up ambient noise, which results in incomplete decoding. I also don't want to have the microphone volume too high.😥

BI1SFC

BG4JGB The microphone on the handheld device doesn't need to be turned up too loud; normal volume is sufficient. You can use the phone's microphone and aim it at the handheld device's speaker, unless there is particularly noisy background noise, in which case it won't interfere with recording. The advantage of using an external speaker for recording is that you can adjust the angle promptly according to signal changes. For internal recording, you will need a 2.5mm to 3.5mm audio cable.

BG4JGB It can be used internally; ideally, a branch should be created to connect headphones, allowing you to both listen internally and hear the incoming audio promptly for adjustments.

BG4JGB

BI1SFC Okay, thank you!

BI2WD

BH4FYL It won't go to a blank page; instead, it displays a large amount of text and images, but if the image is too big, it will display only a short English sentence.

BH4FYL

BI2WD Thank you for your reply. I received a perfect image this afternoon and have successfully submitted it. ^-^

Ideally, try to receive the signal when the satellite is at its highest point in the sky. The ISS's signal should be strong enough even then.
As soon as I receive it, the polarization changes within a minute, and then I immediately adjust the direction and position to find a stronger signal.

BA7NNC-JOE It reminds me of my classmates; let's straighten out the antenna.

I just filmed a video using an UV K6 to receive SSTV signals last night. https://www.bilibili.com/video/BV1yiUKYpEaB
