The Qatar Amateur Radio Society released a leaflet about the geostationary amateur radio transponders at the IARU Region 1 Conference taking place September 20-27, 2014 in Varna-Albena, Bulgaria. The frequencies quoted are:

Amateur satellite service spectrum used by cell-phone masts in the UK

Amateur satellite service spectrum used by cell-phone masts in the UK

Linear transponder
2400.050-2400.300 MHz Uplink
10489.550-10489.800 MHz Downlink

Wideband digital transponder
2401.5-2409.5 MHz Uplink
10491.0-10499.0 MHz Downlink

In the UK the 10475-10500 MHz section of the Amateur Satellite Service allocation was auctioned by Ofcom for nationwide cell-phone backhaul links. The winner of the auction was T-Mobile(UK) now part of the phone company EE. The use of this segment of the band by cell-phone masts may cause problems to UK amateurs wishing to receive the transponders. See this spreadsheet of spectral masks for the 10 GHz links.

Gunter Krebs reports on his Space Pages that Es’hailSat has signed a contract with MELCO to build the Es’hail-2 Geostationary Comsat. Es’hail 2 is a planned communication satellite operated by Es’hailSat, the Qatar Satellite Company. It will also feature an radio amateur payload.

The new satellite will be positioned at the 26° East hotspot position for TV broadcasting and significantly adds to the company’s ability to provide high quality, premium DTH television content across the Middle East and North Africa. It will feature Ku-band and Ka-band transponders to provide TV distribution and government services to strategic stakeholders and commercial customers who value broadcasting and communications independence,interference resilience, quality of service and wide geographical coverage. Es’hail 2 is expected to be launched at the end of 2016.

In September 2014, a contract with MELCO was signed to build the satellite based on the DS-2000 bus.

Es’hail 2 will also provide the first Amateur Radio geostationary communication capability linking Brazil and India. It will carry two “Phase 4″ Amateur Radio transponders. The payload will consist of a 250 kHz linear transponder intended for conventional analogue operations in addition to another transponder which will have an 8 MHz bandwidth. The latter transponder is intended for experimental digital modulation schemes and DVB amateur television. The uplinks will be in the 2.400-2.450 GHz and the downlinks in the 10.450-10.500 GHz amateur satellite service allocations. Both transponders will have broad beam antennas to provide full coverage over about third of the earth’s surface. The Qatar Amateur Radio Society and Qatar Satellite Company are cooperating on the amateur radio project. AMSAT-DL is providing technical support to the project.

Tuskegee Airman Col. Charles E. McGee at AMSAT Symposium

Tuskegee Airman Col. Charles E McGee

Tuskegee Airman Col. Charles E McGee

The AMSAT symposium committee has confirmed that one of the original Tuskegee Airman, Col. Charles E. McGee, will be attending the conference on Friday, October 10. Col. McGee will give a special presentation at our symposium on his experiences as a Tuskegee Airman and as an Army Air Corps and Air Force Pilot. A short question and answer period will follow.

Born on December 7, 1919, McGee rose to the rank of Eagle Scout in the Boy Scouts and, shortly after WWII broke out, joined the Army. He became a pilot in what was dubbed the Tuskegee Experiment, the first squadron of African American pilots, also known as the “Red Tails” from their red markings on the tails of their aircraft. Col McGee and his Tuskegee colleagues fought two wars—World War II and the war on segregation. This required them to develop an unprecedented level of discipline, excellence and fortitude to achieve success.

In World War II McGee flew numerous aircraft, including the famous P-51 Mustang as part of the 332 Fighter Group, one of three groups designated as the “Red Tails.” He provided fighter escort for the B-24 Liberator and B-17 Flying Fortress bombers over Germany, Austrian and the Balkans. He holds a US AirForce record of 409 fighter combat missions flown in World War II, Korea and Vietnam. Col. McGee received numerous awards for his service, including the Legion of Merit, Distinguished Flying Cross, Bronze Star Medal, and Air Medal with 25 oak leaf clusters, amongst others. In 2007 Col McGee and the surviving Tuskegee Airmen were awarded the Congressional Gold Medal by President George W. Bush.

Col. McGee’s presentations are an inspiration to all. He demonstrates, through his life lessons, the need to persevere despite all obstacles and to do your best in all endeavors. Do not miss out on this opportunity to meet this remarkable living legend.

SpinSat – Credit Naval Research Laboratory

On Sunday, September 21 at 0522 UT SpaceX plan to launch a Falcon 9 from Florida carrying the satellite SpinSat with its amateur radio payload to the International Space Station (ISS). UPDATE: Report on the successful launch at http://www.spaceflightnow.com/falcon9/013/140921launch/

On arrival at the ISS it will be put into storage until deployment, later in the Fall, from the airlock of the Japanese Experiment Module (JEM).

Developed by the Naval Research Laboratory (NRL) SpinSat is a 56 cm sphere weighing 57 kg that has 12 Electronically-controlled Solid Propellant (ESP) thrusters spread in pairs throughout the surface of the satellite. They will be fired in pairs to spin the spacecraft. With just primary batteries and only 4.8 grams of fuel this phase may last between three to six months.

The spacecraft will be used to calibrate the space surveillance network. Lasers will be fired at SpinSat from the ground, the light reflected back will be measured to determine where in time and space the satellite is passing overhead. SpinSat will also model the density of the atmosphere.

The IARU Satellite Frequency Coordination Panel report that SpinSat carries a 2 watt RF output 9600 bps AX.25 packet radio store and forward system on 437.230 MHz.

ESTCube-1 at press conference in Tallinn before shipping January 21, 2013 – Image credit University of Tartu

I’m glad to announce that after more than a year of preparations on Tuesday, September 16, 2014, the team are starting to deploy the electric solar sail tether on-board ESTCube-1.

The process of burning the tether end-mass and spool locks and reeling out the first few centimeters of tether will start during the 09.06 – 09.19Z pass over Estonia.  This is a high pass and should be visible over most of the Europe.

The next good passes listed below (all in UTC) will be used to download images the telemetry logs and the images:
10.43 – 10.56
18.39 – 18.51
20.15 – 20.28

ESTCube-1 image of Estonia and its neighbours

ESTCube-1 image of Estonia and its neighbours

During the locks release process and after reeling the tether out some centimeters, images will be taken.

The other shorter passes during the day will be used to download the experiment data as quickly as possible (in Estonia, all daily passes are visible, but lowest ones are just couple of degrees above the northern horizon).

If everything is OK with the tether, additional unreeling will take place in coming days.

If you are interested in receiving ESTCube-1 during those exciting passes, the UZ7HO 9600 bps packet softmodem and an Online Telemetry Decoder by Mike Rupprecht DK3WN can be used. But basically any 9600 bps G3RUH TNC or decoder can be used to receive ESTCube-1.

We are looking forward to receiving your reports on the address es5e AT estcube DOT eu, and we would really appreciate if you would also send received data in live, using Mike’s decoder.

With best wishes,
