I ran a...Actually Ken, this got me thinking a bit. I ran a signal matrix plot on K248CH and it's illuminating.<br /><br />http://radiolink.org/k248ch.png<br /><br />This map uses the NPR Labs thresholds of 47dBu for mobile/car listening (green), 65dBu for indoor listening (yellow), and 73dBu for portable radio listening (red). The light blue is 40dBu, which I added myself...that's "good car radio" and "hard core home rooftop antenna" listening.<br /><br />Unsurprisingly, the red and yellow are worthless; completely in the mountains. But the green isn't bad. This probably is a decent signal for in-car listening over most of Fort Collins. <br /><br />Sort of. <br /><br />You can't see it unless you zoom in, but it appears there's some terrain shielding around the actual downtown areas of Greeley, Fort Collins and Longmont. So while it's great at covering people driving BETWEEN all these population centers, it's probably not so great in the population centers themselves. :)Aaron Readhttps://www.blogger.com/profile/07971835990882097517noreply@blogger.com
