Missouri S&T ARC has two amateur radio repeaters on top of the Thomas Jefferson Hall South Tower in Rolla, Missouri. These allow operators to use inexpensive handheld radios (walkie-talkies) to communicate over 60 miles away from almost anywhere inside Phelps County, and across the world if going through our internet linking systems. A Technician Class license is required to utilize them. 


VHF 2 meter Repeater: 145.450MHz (offset -0.6MHz) PL 110.9

The VHF repeater operates on 145.450 MHz with a negative 0.600 MHz offset. A PL tone of 110.9 Hz is required. This repeater is connected to the internet via Echolink, a very cool internet-based repeater linking/conferencing system. Due to repeater hardware upgrades Echolink is currently unavailable.
