Don't remember Quincy Street anymore, let alone the tower.
I do recall another station in town, but not the call.

Your Heliax story reminds me of when I was CE at Tulsa University's KWGS.
The off-air audio had a "gurgling" sound to it. On inspection, there was water
inside the coax which was actually boiling. Fortunately, there was more coax
than needed in the run, so the short leaky section was removed.
