I came here for the same silence of RCSO 11001 and 11002 on my Unication G5 AND 996XT 460.200.
So the remark TG 11001 & 11002 is NOT the problem .
Same , very occasional traffic, but not the usual.
Something at RCSO went quiet. Had Priority TG for 11001+11002 and MPD East&West (1001+1002)as secondary and thought it was a Uni programming error.
MPD chatter is constant as usual.
