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
- 449.450 MHz RMRL (103.5 Hz Tone)
- 145.295 MHz (100 Hz) (possible backup repeater in Sterling - listen to Alpha for switch info and possible PL tone info)
- 145.400 MHz (123 Hz Tone) Akron KB0VJJ (another possible alternate
- Field Simplex Frequencies

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.
