Phillip,
I have some land about a mile North of the North Sulphur river on Hwy 19/24, my residence is about 10 miles East of there. Today I checked to see if I could hit the repeater from my land and transmit back home to my wife. I hit the repeater with no problem with a 5w handheld GMRS radio. We both heard each other clearly with no interference. At home I have a Wouxon KG XS20H for a base with a antenna about 50 ft up. I have monitored the repeater some but so far I haven’t heard anyone else on it. So my report is it works great and look forward to using it in the future, thanks RRVARC for putting it up and Haskel for donating it!
