@ Radioman : Mike Sullivan was a DJ a few of us Long Island mokes enjoyed. He'd been on WMID Atlantic City, a gangbuster signal on L.I. beaches, and then jocked on WGBB Freeport, where he was music director in their early 'chicken rock' days.
After a short stay at WGLI Babylon, he went to WGRT.
His DXing pals moaned, 'We'll never hear him again.'
The references I used were both National Radio Club sources. One was their nighttime coverage map book (which of course had no Chicago station on 950 at night). The other was their 1970-or-so AM statio log. Upon a re-check just now, it indeed showed that 'WGRT' was 1000 DA-1.
Lol -- underneath them on the list was WXLW Indy, which was the D-3 station
Good memory you; my error me. Thanx for the correction!
(We never heard Sullivan again. Nor did any of us log WGRT.)
