Yep, I was getting 91.5 Mix from Greymouth,
That used to be The Sound. Looks like they’ve been kicked out of the Greymouth region entirely.
I was hearing fleeting few second pieces on 91.5.
Indeed was The Sound in January 2018.
I can’t pull an ID out, but TV-Expert’s logging & two other references now show 91.5 as MIX from Greymouth.
Seams to be difficult keeping up with West Coast FM outlet changes…
NZ has faded away now.
