Ryan Ing reports he will launch a high altitude balloon with a 434 MHz Slow Scan Digital Video (SSDV) payload from the John Masefield High School Thursday, September 15.

The balloon’s transmitter should have a range of some 500-600 km for much of its flight permitting reception across the UK.

Ryan says: I’ll be doing my first launch around 10am Sept 15 from my sixth form in Ledbury, Herefordshire.  Predicted to burst at 32km, landing somewhere near Leominster.

RTTY, 434.250 MHz, 300 baud, 770 Hz Shift, 2 stop bits and 8 bit ASCII. With SSDV

AMSAT-India Regional Coordinator Rajesh Vagadia VU2EXP reports on the ‘Ham Radio – Practical Insight’ session given to 150 students at Parul University.

Wonderful hands on session on ‘Ham Radio – Practical Insight’ was conducted at prestigious Parul University – Baroda (Gujarat, India) on September 8, 2016. Around 150 Engineering (EC) student & faculties participated in the program & gain knowledge on the subject.

In-depth Presentation on Ham Radio, Interesting Ham Radio Events, Video Documentary & SSTV Live demo was carried out by Rajesh Vagadia VU2EXP. Students were excited to see line by line SSTV transmission on the projected screen. To learn with fun, students were allowed to make collective noise during transmission to observe their effect in the SSTV reception!!!

Number of technical & general queries satisfied in Q&A session. Sunny VU2PMU Shared his Ham Experience & Sardool VU2OPX Selected few student with small Quiz.

VHF Demo (Modulation test) was nicely carried out by GIAR team member Ankit VU3NMQ, Sardool VU2OPX, Sunny VU2PMU & myself. Student & faculties learnt the potential of Ham Radio hobby & enjoyed the event at the fullest.

I thank my fellow hams for their kind support and also thankful to Prof. Jay Patel & Prof. Niraj Tever from Parul University to nicely coordinate the event.

Wish this Ham event act as small SPARK (ignition) & in future some of the student may fly high in World of Amateur Radio!

Thanks & 73’s

The UK Space Agency’s Astronaut Flight Education Programme Support Manager Susan Buckle will be giving a presentation at the RSGB Convention on Saturday, October 8.

Along with Ciaran Morgan M0XTD she will talk about the ten UK ARISS amateur radio school contacts with astronaut Tim Peake GB1SS during his Principia mission on the International Space Station.

These contacts have inspired thousands of young people and introduced them to amateur radio in a new and exciting way.

The full schedule and booking information for the convention are available at http://rsgb.org/convention Twitter hashtag #RSGBconv2016

An RSGB video celebrates these historic school contacts and the range of linked activities the schools have enjoyed.

Beginning with the exhilaration of the launch, it follows the competition for schools to host the ARISS contacts, and showcases the variety of science, technology, engineering, maths (STEM) and arts activities that helped pupils to understand more about space and amateur radio.

The contacts themselves, often led by newly-licensed pupils, were the successful culmination of many months of work and anticipation.

Balloon FM Transponder Launch

a-dutch-balloon-launchAt around 1100 GMT on Sunday, Sept 11, a Dutch High Altitude Balloon will launch with a UHF/VHF FM transponder, 23cm ATV transmitter and beacon, the range should be over 500 km.

The weather balloon will be launched from the Netherlands, amateur radio stations in nearby countries have to wait a while to hear the signals until the balloon reach a higher altitude! (the maximal altitude might reach 30km it also did in the past!).

Balloon transmitters frequency information:
Beacon:  145.450 MHz (100 mW FM/N).
FM crossband voice transponder uplink: 432.550 MHz downlink: 145.475 MHz (1 Watt FM/N).
ATV video transmitter 1252 MHz (1 Watt FM, camera looking down to earth).
The balloon camera video stream can be world wide seen on the website (see the urls below).

Ground control stations:
PI4RCG      7.080 kHz, 3.650 kHz (+/- 10kHz QRM).
PI2NOS    430.125 MHz (+1.6 Shift) ground repeater in the Netherlands (also audible via echolink).
PI3UTR    145.575 MHz (-0.6 Shift / 77Hz) ground repeater in the Netherlands (also audible via echolink).

The satellite Pratham built by students at the Indian Institute of Technology Bombay is expected to launch on the Indian PSLV-C35 mission planned for 0342 UT on Monday, September 26, 2016.

AMSAT-BB indicate the Pratham CW beacon on 145.980 MHz is active

Pratham, a 300x300x300mm satellite with a mass of 10 kg, aims to measure total electron count in a 800 km altitude Sun Synchronous Orbit (SSO).

Aayush Yadav of the Pratham team writes:

We, students of IIT Bombay, are glad to inform you that our project, Pratham, is ready and expected to launch with PSLV-C35. We would be really happy if  you all joined us in receiving our satellite’s beacon, details given below:

The beacon is estimated to switch on in the window of 25-30 degrees North and 4-8 degrees East as per the current TLE’s. Once switched on, it will remain so through out it’s orbit. The telemetry data will be switched on only over Europe (France) and India because of our power constraints. If you could, please receive the beacon and/or telemetry of the satellite and report back to the mail id’s as given below. The information for the satellite transmissions is given below,

Frequency: 145.980 MHz
Modulation: CW
Words per minute: 30
Power Emitted: 0.2 W (23 dBm)

Telemetry: To be switched on only over India and Europe (France)
Frequency: 437.455 MHz
Modulation: FSK
Rate: 1200 bps
Power Emitted: 0.06 W (18 dBm)

Kind Regards.
Team Pratham
