A few things to watch here:
1) Where will the new transmitter and tower site be. (I predict it will be at the same location as the 1420 and 1490 towers, in fact possibly using one of those towers.)
2) What will be the power output. (If they're going to use the same tower as, say, the 1490 station, I'm not so sure (and engineers, please correct me if I'm wrong) that the station can go back to its 5kW day/night operation; in which case, I would guess a 1kW day-night operation unless the FCC cuts the night power.)
3) What will be the new format. (My prediction would be the oldies format currently on 1490 would go to 590 as a simulcast with the 1490 frequency eventually being turned off for good.)
Of course, we'll wait and see if the FCC approves the sale first.
