The old site (100kW @ 432 meters side mounted antenna) had an average distance of about 52 miles from the tower to the 60db contour.
The new site (77kW @ 505 meters top mounted antenna) is an average of 56 miles. Both these were numbers consultants projected when the move idea was first hatched.
The full 100kW might push the 60 out another 5 miles.
But that does not take into account the "bounce" 106.7 engineered into the sidemounted antenna. That can gain easily 3-4 db and sometimes a little more. Talking about consultant's "circles" does not tell the whole story. 50/50 contour maps and pop counts are for the GM and GSM.....the tech guys know antenna performance and rf propagation are still very much "smoke and mirrors" because there are so many variables which are difficult, if not impossible, to predict.
Jambox is telling us there is secret Cumulus stuff brewing.....he may know some insider poop......and then again.....maybe not.
But my guess is there is something more to this story. Widows son does make a point about getting agreements to move other stations out of the way. Maybe the "secret stuff" going on will be even better at 100,000 watts.
But then......isn't everything better at 100,000 watts??!!
