Original Announcement:
Our April 11, 2015 flight will be a first for EOSS! We will launch 3 balloons in sequence to support the Colorado Space Grant Consortium. Since this will be an unusual flight, we encourage everyone to come out and support as we launch and track all 3 balloons from our Eaton launch site.
- Click here for the Flightpath Prediction.
- Updated Field Frequencies: To accommodate the additional tracking traffic we are using additional simplex frequencies (listed below). Please program your radios in advance, some radios will default to a repeater shift for these frequencies. Trackers should monitor the repeater frequency and QSY to simplex at the direction of the Tracking Coordinator (Alpha) - monitor both if possible.

- Update 4/7/15: Revised Flight Plans to REV C. Changed Launch Site Simplex to 446.050

Note to all trackers!!
- Please update your TrackPoint per instructions mailed to all trackers by Nick, N0LP. Do this so you are not doing it at the last minute.
- Make sure TrackPoint is not set to Adaptive Beacon, set your station to beacon every 10 minutes. This is to minimize congestion on the 144.34 APRS frequencies
- If you move to monitor the top APRS payloads, do not transmit on those frequencies.
- Program your radios for 446.100, 446.150, and 446.200 for simplex field operations. Add 446.275 for some car-to-car comms.
- Fire danger is high. Do not park where your hot car may start a fire. Do not park in the dry grass.
