EOSS-317 Metro State University - Intro to Space

Payloads developed by student teams from Metro State University's Introduction to Space classes

One 3000g balloon or two 1500g balloons.  Flight predictions can be found here.  Live flight tracking the day of the flight is here.

If cloudcover exceeds 5/10ths, the balloon will be split into two exempt 1500g balloons:

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 (Assuming we are flying out of Windsor).
        • 448.450 MHz (-5 MHz Offset, 100.0 Hz Tone) PPFMA repeater (Assuming we are flying out of Deer Trail).

        Simplex Frequencies:
        • 446.100 MHz Balloon #1 Field Simplex 
        • 446.150 MHz Balloon #2 Field Simplex
        • 446.200 MHz Balloon #3 Field Simplex
        • 446.275 MHz Car to Car drive out Simplex
        (Note that some radios assume these are repeater frequencies and attempt to put a 5 MHz offset in the transmit frequency automatically)

        Legacy 2M Simplex Frequency (not generally used due to desense/interference issues with the 2M APRS packets)
        • 146.550 MHz Simplex

2M Direction Finding Frequencies:

  • 144.340
  • 144.360
  • 144.905
  • 145.535
  • 145.645
  • 145.710
