I find this app to very cool with what potential FM stations can be received from a location, the terrain between transmitter and location, and signal strength. I do find FMSCAN to be much more accurate however since it doesn't overestimate stations at higher altitudes. Anyone else use this app? If so, how do you like it compared to FMSCAN and other DX sites?
 
It's a very useful app. You will not be surprised to learn that a lot professional broadcast engineers also have it on their phones, to look up station signal contours when they are away from their office PCs.

I have to disagree with your description of "over estimating", though. It compares very well with an actual Longley-Rice contour map for those stations I have compared.

Don't get me wrong, I find the coverage maps very good. For instance, WDAS and WRFF showing signal spots at High Mountain Park in Wayne, NJ (about 85 miles away) I was able to receive WRFF and WDAS in that area under normal conditions. I was likely in a spot where 104.3 and 105.1 from NY were weak enough to not have their HD sidebands interfere. However, viewing all the stations I could potentially receive, say in an area not too far from the one mentioned, Bridgewater, NJ. 35 miles from NYC, if I picked a location on the map, it could tell me that WQSR from Baltimore, MD (150 miles away) can interfere with WNEW from NYC. I feel this is where I come in with the overestimating.

Perhaps a case of erring on the side of caution?

Thanks for the information. Just uploaded it. Nice job, especially with the transmitter sites.
