Right now at 1914z on 168.5 Seri Mike Echo calling Sierra Mike Bravo in the clear. SMB has green comms. I install this repeater on Mt Diablo, Ca. about 5 years ago, have not had it in the scanner in awhile, but it seems that they have gone green. I'm sure the SM units are from M.S.S.T. 91105 in Alameda with their 25 foot RHI's. Greg (SF Bay Area)
