Thanks for the link, Terry Kay............
and....... I spoke too soon (don't we all from time to time!); 88.3 is back!, now whether they were shut down by the FCC and just being defiant or just weren't on the air yesterday afternoon, I don't know.
Since I had about an hour block of free time I drove to the area and from as near as I can determine, the transmitter (at least today) is somewhere between 5th Ave N and 8th Ave N between 23rd St N and 27th St N; that's the area where I had experienced interference to WMNF on my car radio. and also when I turned the sensitivity down on my Grundig to the lowest of three levels; I was still getting s strong signal in that area.
I still can't believe the pirate is on that frequency.
Interestingly enough on the way back from there I stopped at the downtown Publix (3rd Ave S, between 2nd and 3rd St S and still had 88.3 on and I thought they had been an abrupt program change as it went from disco to Sam the Sham and the Pharoes...."Wooly Bully", but driving in circles around the parking lot I figured that was someone's XM/Sirius radio's broadcasting on that frequency.
