Happened to catch this test (net?) today at 11:30 PDT on East Simulcast (TGID 9006). Net control was 4057708 (CCRMC), and they were calling facilities in various cities. Check-ins were coming from other 4057xxx users. It concluded at 11:40.Seems there is a new TG on EBRCS. TGID 9006 was being tested today 11/15. I overheard Contra costa regional medical center talking to local hospitals such as Concord, Martinez, Richmond, ect. All were copied loud and clear.
