Very strong downlink from SilverSat over the Eastern U.S. tonight.

All packets were telemetry - no SSDV. Payload included a JPG image that was posted to twitter/x!

My apologies; I did not notice all but the last few errors in uploading times. All of these new times seemed OK.

Recent receptions of the CW beacon. Unfortunately, the current SSDV schedule does not include a single broadcast over Greece.

If I understand correctly, are these new time slots for the SSDV and all previous slots are incorrect?

Painful pass on the SSDV sched:

Silver Spring, MD 2026-03-16T04:56:19

…start time right at my AOS, so if there was SSDV coming down, elevation was way too low for me to see it. By the time SilverSat got higher in the sky, we were back to CW-only.

Next time!!

These are SSDV events scheduled in addition to those posted on 14 March.

Hey all - we inadvertently introduced a SW bug into the payload script, which is why we’re not transmitting SSDV right now. We’re working on it.

Thanks for the update. That likely means the satellite is as healthy as ever, which is great news.
