Let's work together to create a launch event that belongs to everyone, and achieve a collective response from imagination to reality!
Liridice I saw an advertisement stating that QSL cards can be obtained with a certain probability after drawing, but is it always 100% for HAMs?
BH9DWE Liridice Yes, this QSL card was issued by QH. You can also send a request for a QSL card to QH.
BH9DWE BI3SVM_Rinko This satellite was only transmitting SSAT, and it seems that AstSat did not have an SSTV beacon.
BG4QBF BH2VSQ Could you please advise me on how to receive and decode an SDV signal? I have an RTL-SDR-V4.
BI1WJD Welcome to the SSTV transmission activity of the "守听BY1BY" group! Official push from BY1BY The specific launch times and frequencies are as follows: Scan the QR code to join the QQ activity group and communicate (HAM, please enter your call sign in the verification information section): 73！
BG5VLI The HF SSTV frequency I'm using is the standard shortwave SSTV QSO frequency, and I think operating ±5 kHz might be better. Otherwise, there could be interference with communication.
BH9DWE BG5VLI If you can hear it and would like to reply with SSTV, please do so. If the OP (original poster) receives/responds, please reply back.
BI1NWO BG5VLI 这次活动是一次SSTV通联活动：QH OP使用图片进行CQ，如果收到友台回复，将暂停CQ（发射新图片），优先回复友台，完成QSO。 我们热烈欢迎大家与我们在频率上完成QSO。 和日常通联一样，和QH完成QSO后，总可以【和QH】换卡。QH也将上传通联日志。 别的活动卡面需要和对应的负责团队沟通，这个QH没有权限管理。
BH9DWE BI7BST The organizers are overwhelmed, so we'll proceed on a case-by-case basis. We will also update this post before each release to keep everyone informed. If anyone has specific needs, please let us know here.
Lynx I'm going to follow up on that. Previously, using amateur radio for advertising on Taobao resulted in a lot of negative feedback, and this situation feels similar.
BH9DWE BG7YOT If I can identify the main elements and call sign, then it's essentially the same as ISS, and might even be more lenient.
BH9DWE Currently, it seems that QH can see someone responding on the spectrum, but cannot decipher the message. It appears there may be a problem with the software itself. We should investigate further.
