Ham Radio balloon to commemorate Sputnik
A replica of the Sputnik 1 satellite

South Africa's * Secunda Amateur Radio Club* will launch two balloons
carrying amateur radio equipment from the Vryburg airstrip FAVB on October
4, 2014 at 0600 to 0800 CAT (0400-0600 UT)

This date marks the start of Space week 2014. They will commemorate the
launch of the Sputnik satellite on October 4, 1957 by attaching an active
model replica of Sputnik to one of the balloons. The replica will transmit
a Morse message on 144.076 MHz.

Please e-mail (christo.kriek  live.co.za) a screen print of the decoded
message with date, time, GPS location, radio and antenna used to receive a
special certificate from the launch team, if you are one of the lucky ones
that can "decode" by ear please mail above info without the screen print.
The transmitter used is a flea power transmitter.

The South African National Space Agency (SANSA) and eight High Schools (80
children) form part of the program. Each school programmed their own data
logger with 2 sensors. The 8 data loggers with sensors will be part of the
payload of the balloon payload. Each of the school children had to write a
Radio Amateur test (10 Questions) as part of their registration and the
results will be used to allocated to their final presentation.

There will be a web link with cameras from the launch site atVryburg
airport, one camera at Hartbeeshoek and one at Secunda High School. Please
send your e-mail info to christo.kriek  live.co.za to get access to the
webcams on the internet.

The first balloon will be launched anytime from 0600 CAT (0400 UT) onwards.

The ground stations will use HF on 3.650 MHz or 7.080 MHz or 20m 14.280 MHz
between the ground control, chase cars, Secunda High School and
Hartbeeshoek. The bands/frequencies may change due to propagation. If your
hear the ground stations operate please keep the frequency clear for ground
control operations. If you have any feedback in tracking the balloons
specifically on descent please report it on the mentioned HF frequencies.

Due to the low APRS Digipeater and IGate density in the Vryburg area radio
hams in the adjacent areas are requested to also help track the payloads as
well.

It is vitally important to retrieve the payloads since there are data
loggers on-board from several schools in the Secunda area. They need the
data to complete their assignments.

A High Altitude Glider will also be launched the same morning as the High
Altitude Balloon Experiment, HABEX on 4 October 2014.

On the same day at Secunda High School, Secunda, Unisa University will also
have a ROBTICS exhibition. SANSA will also have a presentation via the
webcam about GPS's the same day.
