EOSS-228/229 Equipment Qualification Flights - Recap

Original Announcement: 

This will be an exempt flight of two 1200g balloons to test and flight qualify new beacons.  Updated 9/30/16 1100: Revised weights on plan, swapped parachutes.  Payload plans updated to Rev B.

The predictions from Randy can be found here:  http://ruc.noaa.gov/sdb/predict_0.htm . 

Please see below for updated qual payload frequencies to program into your radios.  In addition to new equipment, the qualification payloads will carry some different antenna configurations for evaluation.  To facilitate this trackers may be asked to shift from 144.34 to receive the qual frequencies depending on position.  Ensure that you do not transmit APRS on the K0SCC payload frequencies, since this could interfere with evaluation.  Therefore you should ensure your beacon is off prior to QSY.  The KC0D paylaods will be under evaluation as digi's, so APRS transmissions on those frequencies are acceptable.  Trackers may also be requested to transmit DTMF, so review procedures for your radio.

TR Breakfast: 
Launch site will be at Windsor, so we can meet for breakfast at Johnson's Corner, I-25 Exit 254. Meet there at 6:00 and leave for the launch site by 7:00. Tim and I will probably not be at breakfast. All trackers should proceed to the launch site and disburse from there. Exceptions will be Chris, KBØYRZ and Dave, KBØLP who will be our tracking pioneers. There is a series of new frequencies for this qualification event. See the email from Nick or the Web pages so you can program those frequencies into your radios. Nick also sent out a message regarding new call signs for the new payloads. Adjust TrackPoint accordingly. Note the first launch will be at 8:00 and the next may be as much as an hour later. Bring snacks and water for a longer day. Thanks to all the trackers for spending their nice Saturday recovering payloads. EOSS appreciates your time and efforts!
