I can appreciate where some of you are coming from, but don't worry. If you can't get the signal now, if EMF wants you to listen, they'll put up a translator. We barely get 94.3 in DeKalb and Sycamore...but we get it rock solid now on 105.3, which picks it up from 94.3 FM from a Com Ed/Exelon antenna on the south side of town.
This will actually cost them some, because some of the translators they just got on the air will be within 15 miles of the new transmitter. But it also saves them on tower maintenance and electricity. The higher population is obvious, but remember, they want to serve a target audience. If you are not in it, then they don't have you as the highest priority at the moment.
Finally, given no interference from another station, many Class A FM's do better in car stereos, with outdoor antennas. That's why you can get it, and probably still will after they move.
Then the question becomes...what happens to the old WJKL tower? EMF can use it as a backup, or sell it, or use it to pay the bills by renting tower space. They likely won't do the latter.
