今早赶上附近山顶拿八木天线和宝锋的5R接收图片，遗憾失败，但是检查我的频率设置正确，天线在卫星过境之前的测试里功能也正常，过境途中我也因为多普勒效应调整了频率，请大佬指正我是还有什么没有注意到的地方吗？或者是我用的设备和天线不对？

先录音，完了再慢慢解码

再好好检查一下哪里不对，我A证的时候收泉盛UV2和钻石的42cm软GP 都是接收了很多张图片，申请了几个奖状。

@"BH6ABO"#p36340 我确实在跟着追踪软件旋转天线了，有时候也能听到一点声音信息，但是绝大多数都是杂音😭

@"BG8KUQ"#p36342 我还有一根771天线，要不下午我再去拿它试一下？

@"BG4JGB"#p36345 还是找高角度的时候接收，信号强。熟悉了就容易了。根据你的描述，是不是没有对准啊，要提前更新星历哦

@"BG4JGB"#p36347 GP天线，注意方向，要把它天线当做DP那样对着卫星，不是指向。

从下面这个火腿的报告看来，ISS放鸽子了，这次普遍没人收到SSTV信号（仅10.8有一个Heard报告） https://amsat.org/status/ 另外推一下我写的攻略 https://hemind.github.io/posts/first-sstv-reception/

@"AJ6SS"#p36356 好像不对，看这个群组还是有不少人收到了 https://www.facebook.com/groups/215192108812824

@"AJ6SS"#p36357 其实没放鸽子但是确实部分时段关闭了

@"AJ6SS"#p36356 看到您说手台天线的垂直方向要对准空间站的位置，是不是意味着天线应该垂直于地面？如果是的话空间站的高度角是不是对于手台天线来说没有影响？

What are some ways to better receive SSTV images transmitted from the ISS?

BG4JGB

This morning, I managed to get to the top of the nearby mountain to retrieve my Yagi antenna and Bao Feng's 5R receiver. Unfortunately, I was unsuccessful, but I checked that my frequency settings were correct, and the antenna functioned normally during testing before the satellite passed overhead. During the pass, I also adjusted the frequency due to the Doppler effect. Could you please point out if there are any other things I missed or if my equipment and antenna are not suitable?

BH6ABO

接收注意天线的极化方向也就是需要手腕旋转自己的天线达到最佳
解码最好使用线录，
接收设备最好使用SDR 加上多普勒插件
SSTV是ham的必修课无论如何SSTV不是数字信号不管怎么样都会有损失，如何减少损失需要在每一个环节下功夫

BG4JGB

BH6ABO I did indeed follow the tracking software's antenna rotation, and sometimes I could hear some audio information, but most of it was just noise.😭

Jason

First, record the audio, then decode it slowly afterward.

BG8KUQ

Let me double-check everything again to make sure there are no errors. When I applied for my A license, I submitted photos of the QuanSheng UV2 and Diamond 42cm soft GP, along with several award certificates.

BG4JGB

BG8KUQ I also have a 771 antenna. Would you like me to get it and try it out this afternoon?

BG8KUQ

BG4JGB It's easier to receive a strong signal when using a high-angle antenna. Once you get used to it, it becomes straightforward.
Based on your description, it seems like you're having trouble aligning something. You should also update the star chart in advance.

BG8KUQ

BG4JGB GP antenna, pay attention to the direction; it should be oriented towards the satellite like a DP antenna, not pointing in any specific direction.

AJ6SS

According to this ham radio report, ISS failed to transmit, and no one received SSTV signals (except for one report on 10.8).

Also, please give my guide a thumbs up!

It seems there's an issue; many people in this group have received it.

BG4JGB

AJ6SS If you mean that the antenna should be oriented vertically, pointing towards the ISS's position, does that imply that the antenna should also be vertical relative to the ground? And if so, would the angle of elevation of the ISS have no bearing on the antenna?

BG2EFX

AJ6SS Actually, I didn't abandon the project, but I did temporarily suspend it during certain periods.

AJ6SS

BG4JGB
No, if the handheld antenna's dipole is oriented vertically, then its main lobe will be horizontal, not aimed at the space station.
A better approach is to position the antenna horizontally, aligning its vertical axis with the direction of the space station's orientation on the horizontal plane. Then, allow the antenna to rotate slowly within the horizontal plane, following the movement of the space station.

BG5BLI

The satellite's altitude has a very significant impact, and it's crucial to find the right time.

BG4JGB

AJ6SS Thank you for your guidance!

BH4HRY

Today, I was monitoring at 80 dB with my UV5RH and all I heard on the sixth floor was white noise. I'm going to investigate the 8木 now.

BG4JGB

BH4HRY Today, from the top of the mountain, the angle to the ISS was less than 40 degrees, and I couldn't receive it with my Yagi antenna. However, there is a transit of 90 degrees tomorrow afternoon, so I think the success rate might be higher.

BI3XGJ

BH4HRY I turned off my radio this afternoon and no one received it. You can check other people's reports at https://www.amsat.org/status/.

BI3XGJ

The SSTV transmission power was quite high, possibly around 25 watts, making it easy to receive. If you don't require a perfectly clear signal, any handheld radio and antenna will work, and the polarization direction doesn't need to be precisely aligned. This is what I received at approximately 14:00 today using the Senhaix 8800 + Eagle 770 puller.

BG4JGB

BI3XGJ I plan to test a near-90 degree angle today in the afternoon, and I'll bring my K6 and 770 with me later to try it out on the mountain.

BI7KHZ

BG4JGB 坐等喜报后去试试😜

通知的是今天下午有学校通联，晚上10:50左右又才重新开始传SSTV，要等明天的了
