Here’s where all the magic of KMNR happens! After audio is sent from the station to the transmitter site, the signal is decoded and sent into the transmitter pictured here. The transmitter by itself has a pretty weak output, so the larger box at the bottom amplifies the power it generates to make the audio suitable for the radio. After this, the amplified signal travels to the antenna at the top of TJ and gets broadcast as a radio wave for everyone in the Rolla area to listen in at 89.7FM! — view on Instagram
