To add a few more bits to the 1100 story, 3WE leased the WKYC Franklin antenna at the TV site until NBC sold off channel 3 in 1990. The new owners wanted the radio off their tower so a scramble was on to find a new site. I believe it was Booth American who owned 1100 at the time. The original WTAM tower on Snowville Road in Brecksville was still standing, now owned by Engineering Consultant Carl Smith and his firm. Carl had grounded out the tower years ago and leased it out to a number of stations, WCRF and WZAK come to mind, and many business radios, plus his own gear, so much so that when he agreed to rent it back to 1100, they could not load the tower up with a full 50K because of all the stuff that was now mounted on it.
And then there was this bit about a null to the north needed to protect a Canadian station near the arctic circle. So for some time, they fed less than 50KW RF into that old tower. I had heard Clear Channel was going to buy land near the Summit-Cuyahoga border to construct a new tower for 1100 and some of its other properties. Did that ever happen? I never heard what they did at Snowville Road to bring the station back up to 50KW, if they indeed did so as some say they never have put the power level back up.
Today, it would be very unusual for any big company to invest money in AM repairs or upgrades as the industry has pretty much relegated AM to the trash heap of history.
