The BATC forum has temporarily been put into read only as a precaution against PHP attacks. As the club is volunteer-run it may take a few days to patch the vulnerabilities. Members should have received an email this afternoon with more details. Thanks for your understanding.

The latest cyber edition of CQTV has just been published. Members should have an email with a link to it. Printed version should be mailed out in the next week or so. A very interesting edition. Thanks to all contributors.

Another SDR# beta. Turn the sound ON. Noise Reduction that leaves cheap AI codegen and textbook recipes in the dust. Watch the noise collapse and hear what you've been missing. This is why you buy an Airspy. Get the beta: airspy.com/download #Airspy #SDR

一块 ESP32-S3,只需要刷写新固件,无需在硬件上做任何修改,即可成为SDR 频谱硬件📡 刷完固件,浏览器连上串口就能看实时频谱和瀑布图。 目前只能接收,十几块钱的开发板能做到这样已经很离谱了。 上一个可以实现这种效果的硬件还是RTL SDR github.com/ESPARGOS/esp-sdr

Mars Express residual carrier on X-Band, must be unlocked from ground station right now as 1-way doppler tracking is keeping it nice and stable. You can see what I see here, but only when I'm at home and have the system online: m0dts.co.uk/dsn-rx
