1. Upcoming Meetings

 

date

 

There will be a number of events on Saturday the 1st November. There will be a Field Day planning meeting starting at 1100 hrs, then a BBQ lunch at 1200 hrs, then a Special General Meeting at 1300 hrs followed by the Monthly Business Meeting.

 

 

2. Victorian National Parks period has record activations

 

Plenty of support from VK2 and VK5 has seen next month’s Keith Roget Memorial National Parks Award reach a record of 31 activated parks and more than 40 portable stations.

John Williams VK2AWJ will be in the Barmah, Lower Goulburn and Burrowa-Pine Mountain National Parks.

While Larry Munns VK5LY is at Murray-Sunset, Paul Simmonds VK5PAS the Lower Glenelg, Mount Eccles and Mount Richmond, with John Dawes VK5BJE at Hattah-Kulkyne.

The cross-border activations from VK2 and VK5 support those in VK3 taking the overall number of stations so far to 44.

Most activity is on 40-metres although other bands will be in use. More
registrations are very welcome.

The Keith Roget Memorial National Parks Award activity period is November the 13th to the 17th, attracting both activators and those working them.

3. Satellites Carrying Amateur Radio Payloads Among Those Lost in Launch Explosion

 

The RACE  and GOMX-2 CubeSats were among more than 2 dozen satellites lost after an unmanned Orbital Space Sciences (OSC) Antares 130 vehicle exploded spectacularly shortly after launch at 2222 UTC on Tuesday, October 28, from the Mid-Atlantic Regional Spaceport on Wallops Island on Virginia’s Eastern Shore. Both satellite packages carried Amateur Radio payloads. The Antares is a new medium-class launch vehicle developed by OSC. The rocket exploded about 6 seconds after launch, sending a huge ball of fire hurtling toward the ground, which set a massive fire at the NASA launch site.

The RACE (Radiometer Atmospheric Cubesat Experiment) CubeSat was a joint project between The Texas Spacecraft Laboratory (TSL) at the University of Texas-Austin and NASA’s Jet Propulsion Laboratory (JPL). Built by a 30-student team, it carried a 183 GHz radiometer, a new science instrument designed by JPL. The spacecraft was equipped to transmit using GMSK at 38.4 k and CW telemetry on a downlink frequency of 437.525MHz.

TSL’s Glenn Lightsey, KE5DDG, a UT engineering professor, oversaw the student project that worked hand-in-hand with NASA staff in creating a satellite that aimed to measure water vapor in Earth’s atmosphere.

“It’s unfortunate, but it is also part of the aerospace industry,” Lightsey told theTexas Statesman newspaper. “The nature of building space vehicles is that it is not a 100 percent reliable process. Getting into space is really the hardest part.”

The 2U GOMX-2 CubeSat was intended to test a de-orbit system designed by Aalborg University in Denmark. Karl Klaus Laursen, OZ2KK, is listed as the “responsible operator” on International Amateur Radio Union frequency coordination documents. The Amateur Radio payload proposed using a 9.6 k MSK data downlink on 437.250 MHz. Also on board was an optical communications experiment from the National University of Singapore. The mission also aimed to flight qualify a new high-speed UHF transceiver and SDR receiver built by an Aalborg University team.

The Antares 130 launcher was on a resupply mission, carrying some 5000 pounds of cargo to the International Space Station.RACE, GOMX-2 and the other satellites onboard the rocket were to be launched into orbit from the International Space Station.

The Antares 130 also was carrying the Flock-1d array of 26 satellites as well as Arkyd-3 and Cygnus CRS-3.

4. RSGB Radio Communication Handbook New 12th edition is Now Available!

 

This edition of the RSGB Radio Communication Handbook has been thoroughly updated with many expanded features. You will find a completely revised HF Receivers chapter and the Propagation chapter has also been completely rewritten with an eye on improving clarity and understanding. There are new authors for the sections on Practical Microwave Antennas and the Low Frequencies. Based on the popular Homebrew column in RadCom there is a new chapter which follows the design and construction of an HF transceiver, and provides a host of valuable information and circuit ideas. Expanded chapters include Practical VHF-UHF Antennas, The Great Outdoors, Morse and Digital Communications with many other chapters have had new, revised and updated parts. Since the last edition, there has been more use of microcomputers, such as the Raspberry Pi, in amateur radio projects; a new amateur band at 472kHz has also been created. These changes have been incorporated into the relevant chapters. Peter Hart’s comparison chart of HF receiver performance has been updated, there’s more on optical communications and new datamodes have been included.

5. 4M Lunar payload update

 

On October 25 Ghislain Ruy LX2RG provided this update on the 4M lunar
amateur radio payload.

Signals from 4M are quite weak. This is not due to a loss of power as telemetry shows normal parameters, but to the attitude of the last stage that places a deep of the radiation pattern in the direction of the Earth.  I hope that Earth’s movement with respect to the inertial attitude of the last stage will give better results in the coming days.

The 4M is becoming a real challenge now, and receiving the signals during flyby will be quite an achievement. A little bit away from the original goal though, but this risk was known.

One sure result is the radiation measurement that showed what was to be expected, and the graphs will soon be pubished on the blog. I hope you will be able to receive during the AMSAT-DL AGM this weekend, but you will have to put 16+dB [antenna] gain at least.

Radio amateurs are encouraged to receive and report the signals

6. Project Horus – Horus 26&27 – Mildura WIA and RSP Flights

 

 This is a short documentary showcasing how the Project Horus group flew two balloons on the same say back in May 2012. The first, Horus 26, was flown with an Amateur Radio voice repeater on board as part of the WIA Annual National convention which was being held in Mildura that year (about a 6 hour drive from Adelaide, our home base).

The second, and at the time more secret balloon was flown for Adelaide based special effects film production house “Rising Sun Pictures”. It carried cameras that were used to capture imagery used to build the special effects shots of the landing sequences in the Hollywood blockbuster movie “Gravity”.
