The United Arab Emirates newspaper The National reports on the Nayif-1 spacecraft developed by Emirati students from the American University of Sharjah in partnership with The Mohammed bin Rashid Space Centre.
Nayif-1 carries a 435/145 MHz transponder (FUNcube-5) for amateur radio SSB/CW communications. It is expected to launch along with other amateur radio satellites such as Fox-1C and Fox-1D on a SpaceX rocket between September and November 2016.

The National says:
Yousuf Al Shaibani, director general of The Mohammed bin Rashid Space Centre, said the satellite’s development was a testament to its commitment to develop Emirati talent.
“There is no doubt that the field of satellite design and manufacturing is a new industry to UAE universities and students,” Mr Al Shaibani said.
“The Emirati students possess the skills and capabilities to design and build a CubeSat as a result of a knowledge-transfer strategy and cooperation between academic and professional institutions that are launching real space projects, enabling students to see the product of their work as a reality in space.”
The satellite is about 10 cubic centimetres and weighs about 1 kilogram. One of its most notable features is that it is programmed to transfer messages in Arabic.
“This is a great achievement and a source of pride for all of us,” said Dr Bjorn Kjerfve, chancellor of American University of Sharjah.

The Appledore Amateur Radio Club helped students at Caen School in Braunton, Devon with their balloon, callsign CAEN_CP1, which transmitted pictures using Slow Scan Digital Video (SSDV) on 434.250 MHz.
The balloon was launched on Wednesday, June 22, 2016 at the school sports day by members of the Pi, Code and Chips after school club. It reached an altitude of 32,540 metres before the payload descended back to Earth by parachute.
The North Devon Gazette say the club – for STEM (science, technology, engineering and maths) subjects – has been working on the balloon project for weeks under the guidance of trainee teacher Bill Harvey. The payload for the flight included a Raspberry Pi mini computer, plus cameras and sensors.
The North Devon Journal reports:
Bill Harvey, an ex-services trainee teacher, is passionate about getting pupils enthused with science and this project was one of many that he hopes to use to inspire children.
“We enlisted the help of the Appledore Amateur Radio Club for ground to air communications as well as the Commando Logistics Regiment RMB Chivenor who provided personnel and equipment.”

The 2016 edition of the book Getting Started with Amateur Satellites is now available from the AMSAT-UK shop.
This excellent book is written by G. Gould Smith, WA4SXM and Friends. This year’s edition has been thoroughly updated and the book is now 176 pages long, covering all a beginner (and an experienced operator) needs to know about getting set up, listening to, and operating through the amateur satellites.
With information on, AO-73, UKube-1, the upcoming Fox-1A, Fox-1B, Fox-1C, Fox-1D, and Fox-1E, it also includes information on several satellites of interest to radio amateurs expected to be launched in the coming year.
As last year, AMSAT-NA and the authors have very kindly allowed AMSAT-UK to print copies in the UK, and make them available from the AMSAT-UK shop at http://shop.amsat-uk.org/Getting_Started_with_Amateur_Satellites_-_2016/p3815740_16038670.aspx
Es’hail 2 is a geostationary satellite which will carry two amateur radio transponders.
The launch of the Es’Hail-2 satellite into a geostationary orbit is planned for the 1st quarter of 2017. The coverage area of the Narrowband (NB) and Wideband (WB) transponders should extend from Brazil to Thailand.
The two “Phase 4” amateur radio non-inverting transponders will operate in the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder is intended for conventional analogue operations and an 8 MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television.
Narrowband Linear transponder
2400.050 - 2400.300 MHz Uplink Right Hand Circular Polarization
10489.550 - 10489.800 MHz Downlink Vertical Polarization
Wideband digital transponder
2401.500 - 2409.500 MHz Uplink Right Hand Circular Polarization
10491.000 - 10499.000 MHz Downlink Horizontal Polarization

A LEILA-2 system, similar to LEILA flown on AMSAT OSCAR-40 (P3-D) will be used for Traffic Control and Telemetry Beacons. The mayor difference is, that this is a ground-based system which will be installed at the Es’hailSat Satellite Control Center (SCC) near Doha in Qatar.
LEILA-2 will analyze the downlink power levels in the passband of the NB-transponder and automatically generate a Siren to remark users to decrease their uplink power.
LEILA-2 is a joint development of AMSAT-DL’s Achim Vollhardt DH2VA and AMSAT-UK’s Howard Long G6LVB.
LEILA is an German acronym for “LEIstungs Limit Anzeige”, which means: Power Limit Indicator.
The following video gives a first insight to the Es’hail-2 LEILA-2 hardware concept

On June 22, 2016 the Indian Space Agency ISRO successfully launched several satellites carrying amateur radio payloads.
The CSAT Swayam satellite was one of those launched. The 1U CubeSat carries a digital store and forward messaging system for use by the amateur radio community.
Rupesh Lad VU2LRD / VU2COE from the College of Engineering Pune CSAT Team says:
“We are eagerly waiting for your reception report of CW Morse Beacon at 437.025 MHz. You can also get the decoded Beacon Data by entering beacon in Swayam Beacon Decoder available on our website.”

Steve Hedgecock M0SHQ with Elk 145/435 MHz Log Periodic Antenna
Steve Hedgecock M0SHQ explained how to operate via the amateur radio satellites at Skills Night hosted by the Chelmsford Amateur Radio Society on Monday, June 20, 2016.
He showed how to use the Elk dual-band 145/435 MHz Log Periodic Antenna to track the satellites and make contacts over thousands of kilometres using just 5 watts from a handheld transceiver.
Steve described how he recently managed to use the AO-85 satellite to contact the Isle of Arran DXpedition station GS3PYE using 5 watts and just the handheld’s quarter wave whip antenna. It should be noted though that a small handheld Yagi is recommended for AO-85.
As part of his display Steve had the popular book Getting Started with Amateur Satellites which is an excellent introduction for newcomers.

Also attending the Skills Night was long-time supporter of AMSAT-UK Sam Jewell G4DDK. He brought along his stall of UHF/Microwave antennas, pre-amps and other useful accessories.
Dave Powis G4HUP had his extensive selection of his kits, plus tools for working with SMD (Surface Mount Devices). During the evening he provided advice to attendees on a range of RF and construction related topics.
Both Dave and Sam have been regular attendees at the AMSAT-UK International Space Colloquium in Guildford which this year takes place July 30-31, further information at https://amsat-uk.org/colloquium/
