ARLX004 Balloon launch 1/21
 
Balloon launch January 21
 
A balloon carrying Amateur Radio is planned for launch January 21
from Boone, Iowa, by a group calling itself the Iowa Balloon
Scientists.
 
Payloads will include a transmitter sending global positioning
information on 446.000 with transmissions at bursts of 9600 baud
once per second;
 
A packet digipeater on 145.550 (-0.600 split), running approximately
one watt and switched on and off at 15 minute intervals;
 
A 144/440 MHz crossband voice repeater (listen on 437.250 (plus or
minus) FM.  There may be some temperature drift. The uplink
frequency is uncertain at this time and will be provided on the
packet beacon.  Since this is the first flight for this payload,
there may be less than optimum operating conditions.
 
The packet digipeater and voice crossband repeater will alternate at
15 minute intervals, with changes planned for 00, 15, 30, and 45
minutes after the hour.
 
Interested amateurs are advised to monitor beacons for details on
other payloads and operating schedules.
 
The launch is planned for 1500 UTC.   An HF coordination net will
meet on 7.155 MHz LSB beginning at 1430 UTC with N0AN as net control
station.
