EOSS-283 Qualification Flight

Update 10:35 2/18/19 Payload plan Rev B posted.

The launch site for this launch will be Wiggins High School.  Follow the link in the previous sentence for google directions, since this is different from our old launchsite.  We will not have facilities, so take a break at the Wiggins rest stop or gas stations for relief prior to coming to launch.

FrequencyList: 

EOSS Preflight Net @ 8 PM MDT preceding night:
        • 449.225 MHz (-5 MHz Offset, 141.3 Hz Tone )  RMHAM Repeater  
        • 146.940 MHz (-600 KHz Offset, 103.5 Hz Tone) RMRL Repeater if the RMHAM machine is down
        • 146.640 MHz (-600 KHz Offset, 100.0 Hz Tone) 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 
        • 446.275 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

DMR will be used when we run out of range to communicate between the trackers and the gound station.  RMHAM wide will be used for drive out frequencies.  There is a new DMR node at Akron.  The information below regarding the No CO repeaters.  Rocky Mountain Ham Code plug samples can be found at this link:  RMHAM Sample code plugs
