NOTE: N0KKZ-17 is a fabricated data file comprised of the initial ascent from the KC0UUO-11 APRS which stopped reporting altitude at 40K feet and data from the K0SCC-11 APRS system which continued to work through the remainder of the flight.

EOSS Flight Day Frequencies:

Tracking and Recovery Frequencies

Preflight Net:

  • 147.225 MHz (107.2 HZ Tone) CRA Repeater, 8 pm MDT preceding night 
  • 146.940 MHz (103.5 HZ Tone) RMRL Repeater if the CRA machine is down
  • 146.640 MHz will serve as a backup frequency

Tracking and Recovery Operations  

  • Front Range and out east 
    • 449.450 MHz RMRL (103.5 Hz Tone) 
    • 145.295 MHz (100.0 Hz Tone) 
  • Field Simplex Frequencies   
    • 446.100 MHz simplex for eoss-191 field recovery operations
    • 446.150 MHz simplex for eoss-192 
    • 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
  • Repeater Coverage Pages - Listings of all repeaters available in the expected flight areas.
  • There may be FRS operations see THIS PAGE for a list of channel numbers and their associated UHF Frequencies.

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.

Tracking and Recovery Operations

Hello Trackers!

We will be launching two heavies for Colorado Space Grant (CSG) on Saturday Morning, 11/16 with a weather date of 11/17.  If we need to fly 11/17, Chris, KB0YRZ will be our Alpha.  It appears this will be a long set of flights heading towards Sterling, Colorado, so we may need to get an early start so we can be closer to the prediction by 7:00.  As a reminder, at the recovery site, be sure to meet and greet the students and learn about their experiments.  They appreciate our interest and it is fun to rub shoulders with our nation�s future. 

We may need to hilltop the 449.450 repeater to reach the ground station operators.  I will take the responsibility to straddle the Sterling repeater and the RMRL repeater as best I can. 

Here�s the scoop.  Please advise Rick (for the Web site updates) and me of any omissions or corrections.

Breakfast:

For breakfast, we can convene at the McDonalds in Ft Morgan at 5:45.  Post-flight meal can be determined by the EOSS Food and Beverage Coordinator, Parker Meer.
