I hope this is the right forum to place this. I'm picking up a Ham repeater from a pretty good distance. Signal is weak and the audio is scratchy, but I can hear it pretty good. The callsign is N4GIS, frequency is 147.015. After a lookup, this repeater is located in Cartersville, GA, and I'm near Decatur, AL. This repeater is 137 miles from my house. I'm not using an amp and I'm only using the RS 20-176. Is this a very rare occurance, or is the wind just blowing the right direction tonight?
