EOSS-117The predicted track below was made using winds aloft data acquired during the ascent of EOSS-116. Since this prediction was made available prior to liftoff of 117, I think it's fair to use it instead of the early morning predictions. This doesn't qualify for the record books though as I submitted neither this nor the early morning predict.

EOSS wishes to express our sincere appreciation to the stations above who iGated the balloon APRS telemetry onto the internet. Of interest for this flight, we had a payload, KC0ZAP-11, on the national APRS frequency of 144.390 MHz. This essentially revealed several iGate stations around the state. N0NHJ who was actually on the chase teams left his home iGate up and running from Glenwood Springs, KD0H from Steamboat Springs, and K0QED from Colorado Springs. Cool. Many of you have i-gated before but did you know I publish predictions for i-gates? I keep a list of everyone who has ever i-gated an EOSS balloon flight on frequencies other than the national 144.390 freq. If you have ever igated an EOSS balloon on any frequency other than the national, you're in the list. 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 28 i-gates. If you are a national frequency iGate and want to be added to the prediction list send me you callsign, latitude, longitude and latitude of your iGate and I'll include your station in future predictions. 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. Customer

The audio was recorded with VOX active so time has been compressed by the removal of silence on the repeater. Events unfold in their true sequential order.
I'm attempting to capture snippets of audio from various payloads that have something semi distinctive beyond just a packet bleep. So ...
