Es’hailSat has tweeted their geostationary satellite Es’hail-2 is expected to be launched by SpaceX in the 4th quarter of 2018.

Qatar’s Es’hail-2 satellite will provide the first amateur radio geostationary communications and is capable of linking amateurs from Brazil to Thailand.

Es’hail-2 will carry two “Phase 4” amateur radio transponders operating in the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder intended for conventional analogue operations and an 8 MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television.

On August 2 the company tweeted the launch information in response to a question about the launch date from Eric Ralph https://twitter.com/eshailsat/status/1024898547165093890

On July 31, 2018 Michael Baylor @nextspaceflight tweeted:
A new #SpaceX Falcon 9 arriving at the Cape. The most likely scenario is that it is B1050.1 for the Es’hail mission. @13ericralph31 is reporting that B1046.2 will launch Merah Putih, making B1049.1 the most likely choice for Telstar 18V.

Students learn about Amateur Satellites at College Workshops

To popularise Ham Radio in western India two events were conducted back to back recently by Rajesh Vagadia VU2EXP Regional Coordinator AMSAT-INDIA.

LDRP College Gandhinagar - VU2EXP 2018-07-12

LDRP College Gandhinagar

LDRP College Gandhinagar

‘Ham Radio for GenX’ – Full day workshop with demo was conducted at LDRP College Gandhinagar (Gujarat – India) on 12th July 2018. More than 70 EC students + faculties participated in this awareness event.

Program was inaugurated with kind presence of dignitaries from
GIAR, LDRP, IEEE, ISRO & AMSAT-INDIA.

From GIAR, OM Pravinbhai Valera VU2CPV (Joint Secretary) & OM Jagdishbhai Pandya VU2JGI (General Secretary) blessed us with their kind presence.

Presentation on ‘Antennas for Space Application’ was conducted by Dr. Ramesh Kumar Gupta (SAC-ISRO).

Ham Radio history & Introductory session was nicely conducted by Jagdishbhai Pandya VU2JGI with several interesting examples.

Thereafter Rajesh Vagadia VU2EXP gave good overview on Satellite Communication, Digital Communication, APRS, RDF, IOTA, SSTV & RTL-SDR etc. technology.

Live demo of SSTV was conducted which was very much enjoyed by the students & faculties. VHF demo with mock drill was simulated by VU2EXP Rajesh, VU2JGI Jagdishbhai, VU3IKI Ke Ke, VU3EXP Sakshi & team.

Ham Radio stuff were exhibited incl. VHF/UHF Rigs, PSU, Antennas, Digital Interfaces, Cables, SWR Meter, attenuator, FUNcube satellite model,
QSL Cards, Awards, etc stuff was displayed for the knowledge of the students.

We also got nice support from other fellow hams incl. VU3DVA Deepakbhai, VU3GLY Priyesh, VU3DSJ Dipakbhai, SWL Abhigna etc team.

We had guest presence of Dr Narendra Chauhan Sir (IPR) & Prof. N. N. Jani Sir in the event.

I am thankful to Prof. Dave Sir (HOD – EC), Prof. Mendhe Sir (EC), Mr. Nilesh Makwana (IEEE) to nicely coordinate & support the event.

Program concluded in hope to have good number of future hams from the Institute.

‘Ham Radio Practical Insight’ titled workshop was conducted at LD College Ahmedabad (Gujarat – India) on 13th July 2018 in afternoon session. More than 65 EC students + faculties participated.

Dignitaries from IEEE, ISRO, LD & AMSAT-INDIA inaugurated the workshop. It was our great pleasure to have chief guest presence of Shri Rajeev Jyoti Sir (Dy. Director SAC – ISRO) & Chair (IEEE) Gujarat chapter in this Ham Radio Workshop.

Rajesh Vagadia VU2EXP explained the latest technology/modes ham world uses & gave quick practical Demos for chief guest. Demo includes CW, Text, Image & Voice transmission/reception with simple VHF Radio sets. The simple experiment techniques used were described. Students were surprised to learn the potential of Amateur Radio & experts appreciate such public demos.

We got nice support from team members VU3EXP Sakshi, VU2UTZ Dinyarji, VU3PMT Mahendrabhai, VU3GLY Priyesh, SWL Ketanbhai during demo & whole event.

ISS SSTV activation July 30-31

ISS SSTV MAI-75 image 9/12 received by Chertsey Radio Club on Baofeng handheld

The Russian cosmonauts on the International Space Station are expected to activate amateur radio Slow Scan Television (SSTV) transmissions on 145.800 MHz FM during Monday and Tuesday, July 30-31.

The Inter-MAI-75 SSTV experiment should be active on:
• Monday, July 30 from 16:00-19:30 UT
• Tuesday, July 31 from 13:25-19:15 UT

The SSTV images will be transmitted on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module. It is expected they will use the PD-120 SSTV format.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

ISS SSTV links for tracking and decoding software
https://amsat-uk.org/beginners/iss-sstv/

You can receive the SSTV transmissions by using an Online Radio (WebSDR) and the MMSSTV software:
• Listen to the ISS when it is in range of London with the SUWS WebSDR http://farnham-sdr.com/
• Listen to the ISS when it is over Russia with the R4UAB WebSDR

Android Satellite Tracking Applications

AmsatDroidFree ScreenshotIn his blog Peter Goodhall 2M0SQL looks at satellite tracking Apps for Android devices

He says “Satellite tracking applications play an important part in using the transponders available to radio amateurs, of course, experiences of them all vary and are very subjective however we are going to explore what is available on the Android platform.”

434 MHz balloon launch from Goonhilly

Goonhilly GHY-1 "Arthur"

Goonhilly GHY-1 “Arthur”

Phil M0DNY is planning to launch a high altitude balloon or two on Tuesday, July 10 from the Goonhilly Earth Station on the Lizard in Cornwall, nearby to the Marconi Wireless Testing Station.

Any help with tracking would be greatly appreciated!

We’re currently undecided between morning or late-afternoon. If we go for morning then we may also launch a second later near-identical balloon later in the day. 5m/s ascent, ~35km burst.

Two Trackers:

• Callsign: 1900 (year of construction of the Marconi Wireless Station)
– Calling Beacon: 433.650MHz.100 LoRa Mode 5
– Telemetry: 434.300 MHz LoRa 20.8K SF10 4/5 Explicit

• Callsign: 1901 (year of first over-the-horizon transmission received at the Wireless Station, from the Isle of Wight)
– 434.100 MHz USB RTTY 50bd 7n2 480Hz

I’ll post updates in #highaltitude on the day when I can.

For tuning in on the pi-in-the-sky LoRa gateway, the config you need is:

CallingTimeout=60
frequency_<x>=433.650
mode_<x>=5
AFC_<x>=y

Thanks, Phil M0DNY

The 434.100 MHz FSK RTTY balloon signal should be receivable across most of the British Isles using a radio capable of SSB reception in 434 MHz. Online tracking at https://tracker.habhub.org/

No radio? Use the SUWS online radio to receive signals from 434 MHz High Altitude Balloons when they are range of London (select USB mode) http://farnham-sdr.com/
