WOW glenn...I just had this conversation a few weeks ago with my son about the drc over nite deal..told him bout Otis and how grants tomb was simulcast on AM and FM...how stairway was played everynite to sync things up ( I listen to the end of stairway now and I still expect to hear that BTO instrumental that lined things up). I was at uconn during that time in DRC's history (remember stat sweeps every hour)..you could walk down dorm halls every nite about 11:50 and hear those opening chords of zeppelin. At that time, DRC was a bit heavier than top 40, especially at nite, with both Otis and Barry Grant playing something deeper than generic Kasey Kasem stuff. While DRC was heard at nite, during the day, you would hear HCN,PLR or WAQY, depending on what dorm you were in and what signal was strong there.
Talking about Barry Grant, I can recall reading somewhere,and I dont recall where, that he had an FCC class 2 license so he was able to able to take transmitter readings overnite, making him expremely valuable to the station. Not sure how true that story is.
