167.625 is definitely CG, heard this one on my 996T, previously it was on a 396XT. I don't know where they were going but I heard on ch 16 - "Lafayette bridge (drawbridge) we need an opening" - hearing the siren in the background, 30 seconds later... "Lafayette we need an opening NOW !" Never heard em being so very forceful on the radio like that before with the bridge tenders. Anyway 167.625 came on barely a minute later one side enc, other clear but I still heard the same siren in the background.
Ive put in all the marine - coast guard tactical frequencies from rr from before, this freq and the 167.1125 arent there, so we as a group on rr we should start getting the freqs we're finding!
I updated the wiki where I found what I had at
United States Coast Guard - The RadioReference Wiki
Dont know what CG ch. my find is so I put in a ?.
