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) north track
- 145.295 MHz (100 Hz Tone) Sterling
- Field Simplex Frequencies
- 446.100 MHz simplex
- 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.

EOSS wishes to express our sincere appreciation to the stations above who iGated the balloon APRS telemetry onto the internet. Did you know I publish predictions for i-gates? I keep a list of everyone who has ever i-gated an EOSS balloon flight. You're all in the list so if you're wondering when the balloon will pop up over your horizon, check out this page for future flights. Currently predictions are being made for 30 i-gates.
We are relying heavily on real time position information available on the net to allow the FAA controllers to have up to the minute location data to assist them in air traffic control.
Redundant stations for the balloon iGating provide excellent coverage. If you are able to iGate we invite you to join the Internet Gateway Team. Contact me (webmaster@eoss.org) to be put in touch with the coordinator. By joining the team, you are giving peace of mind to the iGate coordinator for that flight. He knows you'll be there and he can rely on you.
Naturally, anyone can iGate data onto the net and even if you aren't a member of the team we will welcome your contribution to the internet based tracking effort. If you callsign appears on the findu.com log, you'll be shown as a contributing station as those above are.
Having more than one station covering each APRS beacon means that should a station drop out momentarily, the others can often maintain the data flow.
Thanks again guys! The FAA (and EOSS) are very grateful for your assistance in this endeavor.
Future I-Gaters:
Check out the EOSS I-Gate page for information on how to participate and why we need you.
Current I-Gate Stations:
Guys, the prediction program used to determine the track of the balloon prior to flight can now output a prediction for the Rise, Closest Approach or maximum elevation, 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.
Alpha News
EOSS 164 be a heavy 3000 gm balloon. This will be a long, flight so bring food and water as well as cash for gas! The students will be on the run to catch up with this flight, so we will wait until they arrive.
This will be fun as Mike will be sending up the GoPro Hero to get some cool video. Be sure to download the Payload Plan, thanks Mike Manes.
Unless we decide to cut down early, we will head out I-76 to Exit 125 and go east on Highway 6 towards the prediction. Stay tuned for any changes.
We may migrate to the Sterling 145.295 � PL 100 repeater so I suggest you have it programmed into your radios. Thanks Pappas for the research.
Nice group for these flights! Thanks for coming out on this holiday weekend. I know Chris and Brian really appreciate this effort.
