I ran on of the MSU carrier current stations late 70's to early 80's. The board applied for an FM, but the owner of WJIM held it up for years.
Didn't it eventually come on the air in 1989, and is now WDBM 88.9? They probably would have been approved earlier if they had found a consultant familiar with the intricacies of the convoluted Channel 6 interference rules in Part 73.525. This includes Vertical Only and mixed (Elliptical) polarization, along with a directional angle sector exclusion with a simple receiving antenna to get the affected population down. Many applicants were simply told there was just no way to get approved without a Channel 6 agreement. This limited development of the NCE-FM other than a few powerful stations and the 10 watt ones in Michigan because there were 3 Channel 6 stations with Grade B contours covering most of the state. The rules made it look like you had to locate on the Channel 6 tower, which was also difficult to negotiate. In fact, you just had to get close enough so that the interference ratios could be met. It might have been easier from the WKAR-FM and WKAR-TV tower site instead of the WKAR 870 site where WDBM remains. Of course, all the Channel 6 stations in Michigan are no longer on Physical Channel 6. This resulted in scores of applications in Michigan alone in the latest NCE-FM window.
Channel 6 objections resulted in four noncommercial stations on the 92-108 MHz commercial band, WFBE 95.1 (now a commercial allotment), WDET 101.9, WMUK 102.1, and WVGR 104.1. Other powerful ones were close to or on the Channel 6 towers. 91.7 practically being out of the NCE-FM band allowed WUOM to operate from a very sparsely populated area.
