I am able to pick up the WSP Deforest, and, Tomah posts from the Deerfield, Baraboo, Blue Mound, and, the Milton towers as I am within range of these towers. I can also pick them up on Madison 800, and Madison VH. One day I programed in the frequencies for the Delafield tower,and, the TG for the WSP Waukesha post. (121). To my surprise I could pick them up even though I am well out of range of the Delafield tower. (About 60 miles). My setup is this: Attic mounted RS 20-176 antenna with a Scanner master 137-174 pre-amp mounted at the antenna base. About 75 ft. of RG-8 coax going to a PRO-652. My question is this: Why am I able to pick the Delafield tower when I am so far out of range of the Delafield tower? I can also pick up the Waukesha post on Madison 800, and, Madison VH. I admit that I am no electronic, or, radio expert. The received signal, from the Delafield tower, Madison 800, and Madison VH is strong and clear. Just curious If anyone knows why I can pick up the Delafield tower when I am so far out of range. Any help appreciated. Thank you.
