最近有SSTV活动吗？或者平时去哪里收集活动通知？

这两天就有，ISS在办人类首次进入太空的纪念，信号质量极佳手台感觉用自带天线就能冲，RS38S在做女工程师活动，这个信号会弱，多普勒也很明显。总之，快冲 [upl-image-preview uuid=4cba778a-78be-42d7-9b8a-cb31458eaa1e url=https://storage.hamcq.cn/2025-04-12/1744460280-431778-img-4779.jpg alt={TEXT?}]

@"BH9DFB_AI6YY"#p60778 ISS活动一直到4月16晚上10点，频率145.800MHz，目前看平均每次过境能收两张图，RS38S到4月14凌晨，频率437.825MHz，卫星发两张，能收几张看附近工地繁忙程度

国际载人航天日，纪念 1961 年 4 月 12 日发射载人航天卫星飞船 “东方 1 号 ”和苏联宇航员尤里-加加林（Yuriy Gagarin）返回世界上第一个地球轨道。发射开始时间： 2025年4月12日（星期六）北京时间 01:00 发射结束时间： 2025年4月16日（星期三）北京时间 22:30 ISS的呼号是“RS0ISS”，图像是145.800MHz/FM， SSTV模式是PD120发送。

When are SSTV activities held?

Are there any SSTV events happening recently? Or where do I usually go to find information about upcoming events?

I've noticed this happening recently. The ISS is commemorating the first human spaceflight, and the signal quality is excellent; it feels like I can use my own antenna to connect. However, when RS38S is used for the "Women in Engineering" event, the signal becomes weak, and the Doppler effect is also noticeable. In short, go ahead and try it!

BH9DFB_AI6YY ISS activity continues until 10:00 PM on April 16, at a frequency of 145.800 MHz. Currently, I can receive two images each time it passes overhead. RS38S activity from April 14th morning, at a frequency of 437.825 MHz. The satellite transmits two images, and the number of images received depends on the level of activity near nearby construction sites.

International Human Spaceflight Day commemorates the launch of the Vostok 1 spacecraft carrying cosmonaut Yuri Gagarin on April 12, 1961, which achieved the first human orbit around Earth.

Launch start time:

April 12, 2025 (Saturday) at 01:00 Beijing time

Launch end time:

April 16, 2025 (Wednesday) at 22:30 Beijing time

The call sign for the ISS is "RS0ISS", and the image transmission frequency is 145.800 MHz/FM, using SSTV mode PD120.
