FrequencyList: 

EOSS Preflight Net @ 7 PM Mountain Time preceding night:
        •  449.225 MHz (-5 MHz Offset, 141.3 Hz CTCSS) Rocky Mountain Ham Radio (RMHAM) Repeater and EchoLink *CANONCTY* conference and the Fun Machine linked system
        • 146.940 MHz (-600 KHz Offset, 103.5 Hz CTCSS) Rocky Mountain Radio League (RMRL) Repeater if the RMHAM machine is down
        • 146.640 MHz (-600 KHz Offset, 100.0 Hz CTCSS) Denver Radio League (DRL) Repeater will serve as a backup to the backup repeater 

Launch Site:
        • 446.050 MHz Simplex  
        (Note that some radios assume these are repeater frequencies and attempt to put a 5 MHz offset in the transmit frequency automatically)

Track & Recovery Operations:
        Repeaters:
        • 449.450 MHz (-5 MHz Offset, 103.5 Hz Tone) RMRL repeater

       SkyhubLink - the SkyhubLink system has linked a 2m repeater in Stratton, CO and a 70cm repeater in Akron to the 449.450 machine for our use during balloon flights.

  • Stratton - 146.895(-) MHz, 103.5 Hz (be careful that 2m operations does not affect your reception of balloon packets)
  • Akron - 447.425(-) MHz, 103.5 Hz

DMR:

We will use the RMHAM DMR system on the Rocky Mountain Wide talkgroup

New RMHAM Linked DMR Repeater:

RMHAM has installed a new Linked DMR Repeater at Cedar Point, CO

  • Repeater input frequency: 440.275 MHz
  • Repeater output frequency: 445.275 MHz
  • Color Code 7
  • Time Slot 1: TG 700 (Rocky Mountain Wide)
  • Time Slot 2: TG 720 (Central Regional)

  Simplex Frequencies:
