ARLX005 Balloon launch slated
 
On February 4, 1995, the North Texas Balloon Project, sponsored by
the Lockheed Radio Club in Fort Worth, will launch its sixth high
altitude balloon experiment carrying Amateur Radio.
 
The payload includes a variety of radios and instruments that can
easily be used by any amateur with a Technician or higher class
license:
 
A crossband FM repeater will operate 147.580 receive and 445.850 MHz
transmit; flight data, including GPS position, will be transmitted
by 1200 baud AFSK (packet) on 144.290 MHz; and a live,
elevation-controlled, color video camera will be used with a 10-watt
ATV transmitter, on 439.250 MHz.
 
According to Doug Howard, KG5OA, the ATV frequency is cable
television channel 60, and an outdoor antenna, along with a
television tuned to cable channel 60, should provide acceptable
pictures.
 
The balloon is expected to reach 100,000 ft about two hours after
launch, giving it a radio horizon of about 400 mi.  The launch is
scheduled for 1400 UTC; if it is delayed, the launch will be
rescheduled for February 5 or the following weekends.
