In many ways, this is an even bigger deal; 102.7 had a hefty vent fan system that could move a lot of air. Sure, if the air outside was hot, it means the air inside was hot, too. Usually you can't cool a room using outside air below about +10F degrees above outside air temps. So if it's 90F outside, it's 100 to 105F inside...ugh!
And at 88.1, we didn't really have even that. The transmitter site is an 8x10ft shed with a single 12 inch desk fan blowing air out one of the wall vents, and no insulation whatsoever on the walls or ceiling. Temps routinely broke 120F inside, even when it was only 70 to 80F outside.
