Have any amateur astronomers spotted these satellites, either optically or by radio transmissions? I have not read any mention on SeeSat-l.

Posting here as the two issues need to be closed about before this launch can take place:https://arstechnica.com/space/2024/10/while-ula-studies-vulcan-booster-anomaly-its-also-investigating-fairing-issues/QuoteWhile ULA studies Vulcan booster anomaly, it’s also investigating fairing issues"We have integrated some corrective actions and additional inspections of the hardware."STEPHEN CLARK – 30 OCT 2024 15:13A little more than a year ago, a snippet of video that wasn't supposed to go public made its way onto United Launch Alliance's live broadcast of an Atlas V rocket launch carrying three classified surveillance satellites for the US Space Force and the National Reconnaissance Office.Screenshots from ULA launch video attached (which were discussed on the original launch thread at the time).

The Space Force expects its newest space observation satellites, Silent Barker, to be ready for initial operations early next year, according to the head of U.S. Space Command.Gen. Stephen Whiting told reporters Wednesday that the spacecraft, which launched in September 2023, has been undergoing a series of on-orbit tests for the last year.
Whiting suggested the yearlong testing process is “not atypical” for a new mission like Silent Barker, adding that future satellites in the constellation should integrate much faster. The Space Force expects the satellites to be fully operational by 2026.
