EOSS Flight Day Frequencies:

Tracking and Recovery Frequencies

  • Preflight Net:
    • 147.225 MHz CRA Repeater (107.2 Hz Tone) 8 pm MDT preceding night
    • 146.940 MHz (103.5 HZ Tone) RMRL Repeater if the CRA machine is down
    • 146.640 MHz (100 Hz Tone) DRL will serve as a backup frequency
  • Recovey Operaions
    • 449.450 MHz RMRL (103.5 Hz Tone) 
    • 448.225 MHz (141.3 Hz Tone)  Testing… PL verified 7/2/14
    • 446.100 MHz Field 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.
    • 146.550 MHz Backup field simplex
  • Repeater Coverage Pages - Listings of all repeaters available in the expected flight areas.

Experimenters are welcome to submit websites for linking or overviews which I will post on a page on the EOSS website.


Internet Gateway Stations:

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.

Breakfast

The flight projection is somewhat south about 15 miles.  For breakfast, we can convene at the Deer Trail launch site at 6:00 a.m.  We can discuss this on the net.

Future Flight Schedule 

as of January 15th, 2014

All dates and launch locations should be considered tentative. The WX delay date is indicated by a "plus" x days indicator i.e. +1 means a one day delay is available +7 a one week delay is available. An "n" indicates no available WX delay date.

Enter your email address above and you will receive notifications from the ChangeDetection.com website whenever this page is altered. Instead of entering your email you can visit the site and read all their privacy info if you wish. Just copy the URL to this page so that, if you decide to get alerts, you can paste it into their forms at ChangeDetection.com. Or, if you decide you trust them, you can just return here and enter your email address.

Be ADVISED, this page sometimes goes through multiple edits in a single day when initially prepared and when we close in on launch day, I'm usually informed of any changes and updates that need to be made. So, you can expect to get a fair number of alerts. Each alert comes with an unsubscribe. So, if you get tired of being bombarded, stop the monitor.


The tag for recently edited information will remain in place for a minimum of 24 hours. After that period the tag will remain in place until new updates to the page are made. When the new updates are added, the tags will be moved to indicate that new information.

The tag will not be removed if there are no other changes to be made to the page. This will avoid somewhat misleading ChangeDetection notifications (above) regarding the state of this page.
