900 MHz (33cm) DMR and experimental repeater Daniel, July 26, 2024July 26, 2024 The 900 MHz (33cm) repeater is coordinated with SERA on 927.7250 with a -25Mhz offset.(Pictures pending)Running on DMR, TGIF. We are also experimenting with AX25, FM, and other modes.The antenna is a no-name antenna at roughly 75′ high. I am currently running the LMR-400 feedline until I can secure more hardline. I’m running two Motorola radios, an MCS2000 (M01HX+914W) and an XPR5580 (AAM28UMN9KA1AN). The transmitter puts out 30w however there is some significant loss in the feedline.It interfaces into an MMDVM repeater hat from Winters, BI7JTA.And I built a custom interface cable to bridge each of the radios to the MMDVM board’s DB9 connector.The duplexer is an EMR Corporation 66544/SND 894-960mHz 4-Cavity Pass Notch Duplexer that I found on ebay. 900mhz DMR Repeaters 900mhzdmrmmdvmrepeater
