[João Costa > CT1FBF]

50 students of Rajkot India enjoyed SSTV live demo during visible pass of
ISS

To spread awareness of Amateur Radio, Satellites and ARISS activities in
the region we conducted interesting event recently.

On 12th April 2019 we openly invited students and citizen of Rajkot -
Gujarat to be present and witness SSTV Live Demonstration, that too during
Visible pass of ISS from terrace of my home.

More than 50 students and citizens assembled to my QTH by 18:30 IST
(13:00z). We gave printed ISS tracking chart/ISS crew details to all of
them, and explained how to use chart.

Myself Rajesh Vagadia VU2EXP gave brief talk on Amateur Radio, ISS, OSCAR
Satellites, Life of Astronauts, ARISS SSTV event, Student Outreach Program
etc for one hour. Small display of radio stuff were also kept. Everybody
get excited to learn such new things (for them) happening in Ham Radio
world.

Good Visible ISS Pass of -3.0 magnitude with elevation of 36° was targeted
for Live Demo, calculated for my Grid ML52jh.

With my 3 ele Yagi, VHF HT & recording device we started to track ISS at
19:27 IST (13:57z). Within a minute ISS started to appear from NNW
direction moving towards SE. Students were requested to control their
excitement and to keep silence as we were also recording audio. Soon sstv
signal also get heard on 145.800 MHz. SSTV signal for two images were
received and recorded.

It was exciting experience for all to sighting ISS at the same time getting
signals from it, felt like having handshake with ISS crew! After pass, we
amplified weak audio in Audacity and decoded two images (though bit noisy)
with MMSSTV. Decoded Images were shared with all students as souvenir. It
proved great learning experience for all. Had lots of Q&A till late and
enjoyed light refreshments at end of the program.

As everything was arranged at our home I need to thanks my XYL Kiran,
harmonic Snehal VU3WHO, brother Prakash VU3PLJ and nephew Priyesh VU3GLY
for extending helping hands.

Btw, leading newspaper Divyabhakshar supported this radio experiment &
published good articles (though in regional language Gujarati), pse find
