I have to add my 15 cents worth!

WMAQFM Time was given almost every break on every station!
The word "Stereo" was enunciated. FM stereo vs AM.

Busboards were all over for WLAK-FM 94.
101 102 were also noticed a bit, as I remember.
WSDM - Was that Yvonne?? Smack Dab in the Middle!
Larry the Legend from WIND to WZUU-Milwaukee.
WIND #1 music the late Ron Britain -- still had it! Connie Szerszen at night, so it was WLS, WCFL and WIND on AM, playing music!
W-Gold!
Fire Radio RKO Oldies! To me, THIS was their best. RKO had the AM Top40's (+WOR/99X NYC) but the FMs were basically OLDies and they played good ones! "RKO Gold Mine" PAMS jingles.
Dale McCarren!!!!!! This man died too soon. What a crisp, no-nonsense, authorative voice!
WJJD AM! I remember the news jingle! Their charts were at Radio Doctors and Sears stores in Milwaukee!
WGRT.... 20/20 News! Maybe not at this time, but they used the old Pepper-Tanner "the Now Sound" jingles in 1967.-1968. I remember them well. One guy always into the news said "Boracho!" Clearly loved the radio!
WMAQ Joel Sebastian....... the way he was demoted at WLS and tossed onto overnights was a sin!
WDHF was so close to Top40, I believe.... Ron Dennington(Ronnie Knight) would PD (leaving WOKY, Milwaukee) then Gary Price (also WOKY) would watch the change from DHF to M E T!
WVON! 1450 sister to WNOV Milwaukee "the Soul 45" survey was the same for both cities. "L&P Broadcasting" NOT AT this time, but in 1968, when 860 WNOV, flipped from WFOX.
WEFM WNIB WFMT WGN
Norwood Savings -I'm sure was bought by someone when all the S&Ls Savings & Loans hiccups. Died 1990.
WCFL still Top40, Super CFL was to come with the TM shotgun!

As a kid, I'd go to Chicago, like a geek, and tape the FM stations AND the AM Black stations!

Loved 1470 WMPP ad 1570 WBEE. Both EXCELLENT stations! There was so much good!

Wish I still had those tapes!

Aside, I NEVER liked "Music Radio", but loved "the Rock of Chicago."
Loved "Super CFL" as it was later a Q Format clone of WOKY KCBQ WDRQ WMYQ KSLQ etc.

(Yes, I went to those cities (except San Diego) to tape them. Lotta memories!) Still lotta stuff on You Tube, too.

Thank you so much for posting this!
