Chris et al, AGREM 1670 is in fact a TIS (Traveler Information) station running at 10 watts. It went operational in November 2014, and has been continuously broadcasting local emergency and related information since then, with some brief outages as we upgraded the transmitter and more recently replaced our "player". While we are only 10 watts, we operate under two FCC waivers -- one for power intensity, and the other is for the height of the antenna. It's located at about 125 AGL on a municipal water tower. Both waivers were granted with our initial license because we wanted to cover quite a broad area (about 85 square miles). AGREM is a local emergency management organization formed in 1999 and which has representation from 7 municipalities in SE Chester County, PA.

Regarding comments from others about not seeing the antennae for these stations -- n normally they are ground mounted with a set of radials and the typical height is 40 feet AGL or less and the antennae are typically under 20 feet long as well.
