[amsat-bb] High Altitude Balloon Launch

[Stephen Smith]

Lots of fun with the Cross-band Repeater:
 
 

Arizona Near Space Research (ANSR) is pleased to announce the flight of
ANSR-39. This high altitude balloon flight will take place on Saturday,
September 29, 2007 at 9:00 AM MST (1600 UTC). The launch site will be
announced closer to the flight date and will be based on winds aloft,
tentative site is Maricopa, AZ south of Phoenix, AZ.

The balloon will be a 1200-gram weather balloon, filled with helium.
The expected burst altitude will be 90,000 feet or more. The flight is
anticipated to last about 2.5 hours from launch to touchdown.

The flight will checkout new ANSR beacons and also have the voice
cross-band
repeater.

Our mobile cross band Digipeater will repeat the APRS data to the
144.390
MHz standard APRS frequency and thus will be I-GATED to the Internet for
out
of area trackers. You can track the flight using either of the following
