- drmpeg 2y agoI wonder why the frequency was redacted in this tweet. https://x.com/nascom1/status/1851789221885022416 https://x.com/nascom1/status/1851789221885022416
- viraptor 2y agoMaybe they're hiding the current Doppler shift? Or just trying to prevent noise from randos experimenting in that range?
- ElectRabbit 2y agoThey removed the frequencies from some of the more popular sites. That started during early stages of the Ukraine invasion. But it's still super easy to find them. Usually it takes a few hours until the sat ham guys find them and post spectrums.
