  • Page 20 Operation that transmission on a different frequency. Repeaters are often set up in a fixed location and connected to an antenna that is mounted at a higher elevation to provide better range than is normally available with radio-to-radio (simplex) communications. Locating a Repeater Using GMRS repeaters can significantly increase the range of your radio, but just tun- ing to one of the repeater channels isn’t necessarily going to work.
  • Page 21 Operation Operation KG-905G Repeater Channels Group 04 channels (RPT-15 through RPT-22) have the same receive frequency as Group 03 channels (GMRS-15 through GMRS-22). However, the transmit frequency for these channels is assigned to a frequency specifically designated as a GMRS repeater input frequency.
  • Page 22: Adjusting Volume And Power On/Off
