This is making the e-mail rounds of mid-west ham radio circuits. Working a
high altitude balloon launch might be interesting to AMSAT folks in the
central portion of USA ...
QSO Opportunity with High Altitude Balloon Flight Saturday,
18 July 2009
As part of SpaceJam-3 (www.spacejamboree.com),
DePauw University (www.depauw.edu/acad/physics/base) will
be flying a cross band repeater to allow the Scouts at the Jamboree
to talk with ground stations from a large area of the central
portion of the United States.
Launch will occur at 13:50 UT (8:50 am Central Daylight Time)
from Rantoul, IL (40.29 N, 88.14 W) The target ascent rate will
be 1000 feet/min.
APRS information will be sent over 144.39 MHz every minute under
the call sign, W9YJ-11.
The helium filled balloon will reach a float altitude of 70000
feet (21.5km) about 15:00 UT and will attempt to float at this
altitude for about three hours. During this time the balloon
should travel slowly to the NW from about 40.0N & 87.8W to 40.1 N
& 88.1 W. The descent will begin about 18:00 UT on a slowly
deflating balloon with landing about 19:30 UT.
The uplink frequency on the radio will be 144.36 MHz, and the
downlink frequency will be 446.025 MHz.
The Scouts will be using the call sign WB9SA. If you have a
chance to contact the station, the Scouts will be thrilled to
make the contact! You may also attempt to use the repeater for
a long distance Earth-Balloon-Earth contact with hams from larger
Thanks to Howard Brooks, KC9QBN, Professor of Physics & Astronomy
at DePauw University, W9YJ for making this happen!!!
If you are in the IL/IN area you might catch ATV from our first
balloon going up (100,000 ft) at 8:20 AM CDT Saturday from Rantoul
IL 430 Mhz, with a CW call "DE WB9SA"
