LAUNCH TIMES:
LAUNCH SITE: Windsor, CO (Click Here for directions)
Tracking and Recovery Frequencies
- Preflight Net:
- 147.225 MHz 8 pm MDT preceding night
- 146.640 MHz will serve as a backup frequency
- Tracking and Recovery Operations
- Repeaters
- 449.450 MHz (103.5 Hz Tone) RMRL Machine
- 146.775 MHz -offset (114.8 Hz Tone) Cheyenne north, linked to Albin repeater to east
- 147.165 MHz +offset (114.8 Hz Tone) Albin repeater, east of Cheyenne and linked back to the Cheyenne machine.
- 146.970 MHz -offset MHz no tone Sydney, NE
- Field Simplex Frequencies
- 446.100 MHz simplex for field recovery operations
- Note: Some radios insist on incorrectly placing a negative 5 MHz offset when selecting frequencies from the simplex portion of the 70 CM band. Check your radio and if this is the case. Consider programming in this simplex frequency to a memory channel as some radios have demonstrated the annoying habit of re-inserting the offset if you momentarily shift to a repeater then return to the simplex freq. Check the operation of your radio on this simplex freq to be ready for however your radio behaves.
- 146.550 MHz Backup field simplex

Experimenters are welcome to submit websites for linking or overviews which I will post on a page on the EOSS website.
Future I-Gaters:
EOSS is always in need of I-Gate stations. Check out the EOSS I-Gate page for information on how to participate and why we need you.
Current I-Gate Station:
If you are present at your iGate during the flight try and monitor the tracking and recovery frequency. The ground station likes to check the frequency prior to launch to find out if any stations are out there ready to igate the traffic onto the net for the FAA to monitor.
The prediction program used to determine the track of the balloon prior to flight can now output a prediction for the Rise, Closest Approach, and Set of the balloon for each of your stations. I have posted a prediction page for stations that I have been able to discover geographic coordinates. See the I-Gate prediction page for an example. The page will not be updated daily, however, it will be updated the evening prior to flight for I-gate planning purposes.
I have often been asked by iGaters when they should expect to either start receiving signals (AOS) or expect to see those signals disappear (LOS). This prediction page should answer all those questions for you.
Your Log Files
Our technical committee members would also request you open a log file and record all the packets you hear and forward onto APRS-IS. Whenever there is a technical failure of a package it is always helpful to have the most complete dataset possible to attempt to determine the cause of failure and possible fixes. After a flight send your data files to me (webmaster) and I will distribute them to the appropriate payload builders. They appreciate these logs even if all goes fine during a flight.
Wear warm clothes and good boots. Fill up with gas!
