卫星是1月8日21点28分升起，直到最高点附近才能收到信号，但是因为直接用的手机录音而且地点在大街上，导致干扰很严重，再加上使用的是钻石SRJ77没有使用八木天线最后得到的图像也是一滩烂泥啊（） [upl-image-preview uuid=ec3fad89-b45f-4abc-91c9-1c2d55b01191 url=https://storage.hamcq.cn/2025-01-08/1736346861-683658-6f8d6accc0ae406ad7b4707ae8977856.png alt={TEXT?}]

之后如果有遇到ISS的SSTV活动可以尝试找空旷的地方接收看看我这次活动是在大楼屋顶接收(附近几乎无障碍)，设备是UVK5配原厂天线，手机直接开ROBOT36直接解码当时刚好遇到最大仰角73度接收的成果还不错下图是当时接收的成果 [upl-image-preview uuid=3ec60415-9800-484c-acdf-a46a7df068db url=https://storage.hamcq.cn/2025-01-08/1736355205-208037-485283.jpg alt={TEXT?}]

@"DarkNoir"#p49361 主要是当时地方不够空旷，我只在最高点处才接收到了一些信号，下次去天台试试

昨晚在广州番禺23层楼顶，uvk6+原配天线，也只能收到微弱几秒信号。电波的干扰太厉害，加上头顶飞机不断。失败的一次。

@"ZReaTea-BI6PKM"#p49355 这个卫星功率小，下次赶上空间站的SSTV，效果应该比这好的

@"ZReaTea-BI6PKM"#p49355 有遮挡影响比较大，但是这个星感觉极化影响比较小

U段多普勒比较明显，要随时切换频率，不像ISS的V段，基本变化不大，可以保持一个频率接收，刚21点多过境1区，完成接收并解码，过程频率在825左右大概有10k的变化，效果只能看个大概，接收SSTV根据不同卫星，频率，还得有点策略才行 [upl-image-preview uuid=3ef6b9e5-cafe-4f02-a493-0455819061b1 url=https://storage.hamcq.cn/2025-01-09/1736432269-914487-spacep1.png alt={TEXT?}] [upl-image-preview uuid=4eb502ad-14ed-4976-a568-abe0d1171a5c url=https://storage.hamcq.cn/2025-01-09/1736432273-792480-spacep2.png alt={TEXT?}]

没收到昨天晚上看有一次过境去的13楼天台宝峰5RH PRO 原机天线啥也没收到今晚还有一次过境再试试

@"BI1SFC"#p49481 你这个效果可以啊！我今天在12楼天台用SRJ77收的比这个差很多[upl-image-preview uuid=fdfe105e-bcbb-45d1-99a8-5047b6552c8f url=https://storage.hamcq.cn/2025-01-10/1736515655-749621-hist9.bmp alt={TEXT?}]

刚又接收解码两张，80多度的仰角，跟着频率切换，就一张解码还凑合，本次活动也接近尾声了 [upl-image-preview uuid=76dfe824-ba5d-479c-98c0-e34ea444164d url=https://storage.hamcq.cn/2025-01-10/1736517265-927664-2025-01-10-214813.jpg alt={TEXT?}]

我昨天收到了这两张~ 今天最后一次过境是十几分钟时候的UTC1427 在学校，应该没有机会了呜呜 [upl-image-preview uuid=5662e26d-fd6d-46e6-bb47-78901284fe09 url=https://storage.hamcq.cn/2025-01-10/1736518302-930155-8971382bd40bdcd19e52ebe6e20e2396.jpg alt={TEXT?}] [upl-image-preview uuid=a02cfc85-67db-4ac3-848b-9fe0ca1c8673 url=https://storage.hamcq.cn/2025-01-10/1736518303-93909-c2398bf1693d34c97bd27fa502f09a45.jpg alt={TEXT?}]

First SSTV reception (VIZARD-Meteo)

ZReaTea-BI6PKM

The satellite rose on January 8 at 9:28 PM, and I was only able to receive a signal when it reached its highest point. However, because I was using my phone to record the audio and I was in a public street location, there was a lot of interference. Furthermore, I was using the Diamond SRJ77 antenna without a Yagi antenna, which resulted in a very poor image (）.

BI4NFH

ZReaTea-BI6PKM This satellite has low power; it should provide better results than SSTV on the space station when we can catch up with it next time.

troilus

ZReaTea-BI6PKM The obstruction effect is quite significant, but the polarization effect seems to be relatively small.

DarkNoir

If you encounter SSTV activities related to the ISS later, try finding a clear location to receive them.
During this event, I received the signal from the rooftop (with almost no obstacles nearby), using a UVK5 with the original antenna. The phone directly connected to ROBOT36 for decoding.
Fortunately, at that time, we were able to achieve a maximum angle of 73 degrees for reception, and the results were quite good.
The image below shows the results received at that time.

ZReaTea-BI6PKM

DarkNoir The main reason was that the area wasn't spacious enough; I only received some signals at the highest point. Next time, I will try going to the rooftop.

BD7INC

Last night, at a 23-story building in Panyu, Guangzhou, using the UVK6+ original antenna, I could only receive very weak signals for a few seconds. The interference from radio waves was too strong, and there were also planes flying overhead constantly. This attempt failed.

BI1SFC

The Doppler effect on the U-band is more pronounced, requiring frequent frequency changes. Unlike the V-band used by ISS, which experiences minimal variations and allows for a single frequency to be maintained, the signal passing through Zone 1 around 9:00 PM had approximately 10 kHz fluctuations in its frequency, ranging from around 825 kHz. This only provides an approximate indication of the signal quality. Receiving SSTV requires different strategies depending on the satellite, frequency, etc.

ZReaTea-BI6PKM

BI1SFC This effect is great! The results I got today, using an SRJ77 on the rooftop of the 12th floor, were much worse.

BG4LDK

I didn't receive anything yesterday evening when I went up to the rooftop on the 13th floor using the original BaoFeng 5RH PRO antenna. There was nothing there. I will try again tonight during another pass.

BI1SFC

I just received and decoded two more, with an elevation angle of around 80 degrees. After switching frequencies, one decoding was acceptable. This activity is also nearing its end.

VA3-BI4LPZ

I received these two yesterday. My last transit was about 14:27 UTC this morning.
There shouldn't be any more opportunities at school, I guess.

ZReaTea-BI6PKM

VA3-BI4LPZ The second signal you're showing looks pretty good. I bought a Yagi antenna from JYR and plan to try it out later.

VA3-BI4LPZ

ZReaTea-BI6PKM Thank you (^-^).
