I had the opportunity to help with maintenance of the 448.775 repeater in Mansfield on Feb 18, 2017. While Jim KB0DBJ and Kim K3JAR climbed to the top of the water tower, Steve KM5HT, Bill KF5YIV and Dave KD5DK worked on improving the feedline to the radios in the Yaesu DR-1X repeater. The stock coax appears to be LMR-240 or RG-8 and the reception was significantly improved by running LMR-400 all the way to the radios.
