The launch date for the amateur radio FUNcube-1 satellite remains on schedule for November this year. Coming up this week, on August 22 at 14:39 UT, is the next DNEPR launch from Dombarovsky near Yasny so we are looking forward to the successful insertion of its KOMPSAT5 payload into orbit as this will give greater confidence for the actual FUNcube-1 launch date. http://www.kosmotras.ru/en/news/127/

In the meantime every CubeSat needs to be able to have the capability to charge its on board batteries when already in its POD. Of course this means that we need a suitable battery charger and it needs something quite special so as to be certain that there is no risk of overcharging or other disaster.

The pictures show the charger which was specially designed and constructed by Wouter Weggelaar PA3WEG for FUNcube-1. Smartly presented in a blue anodised case, this charger can be set to charge the Li battery to the best voltage for long term storage, approx 7.6 Volts, and can also be used to enable the final pre-launch testing of the spacecraft and its flight software before launch.

FUNcube-1 carries a 435/145 MHz linear transponder for SSB/CW communications and a 145 MHz 1200 bps BPSK telemetry beacon. Further information at https://amsat-uk.org/funcube/funcube-cubesat/

Join AMSAT-UK

AMSAT-UK_Bevelled_LogoFounded in 1975 AMSAT-UK is a voluntary organisation that supports the design and building of equipment for Amateur Radio Satellites.

AMSAT-UK initially produced a short bulletin called OSCAR News to give members advice on amateur satellite communications. Since those early days OSCAR News has grown in size and the print quality has improved beyond recognition. Today, OSCAR News is produced as a high-quality quarterly colour A4 magazine consisting of up to 40 pages of news, information and comment about amateur radio space communications.

The new lower-cost E-membership provides OSCAR News as a downloadable PDF file giving members the freedom to read it on their Tablets or Smartphones anytime, anyplace, anywhere.

An additional advantage is that the PDF should be available for download up to 2 weeks before the paper copy is posted.

The Membership year lasts for 12 months starting on January 1 each year.

If you join after July 31 of any particular year, then you will receive complimentary membership for the whole of the following year, i.e. join on August 12, 2013, and you have nothing more to pay until Dec 31, 2014.

Now is a very good time to join.

Ofcom Consultation covers 2.3, 2.4, 3.4 and 5 GHz bands

AMSAT-UK_Bevelled_LogoOfcom has published a consultation on the role that spectrum sharing could play in meeting the future capacity demands of mobile broadband and machine-to-machine communications.

Spectrum sharing is the principle of allowing multiple users to exploit the same band of spectrum – rather than it being allocated to a dedicated single user. While not suitable in all circumstances, a key benefit of this approach is that spectrum, the vital but finite resource that underpins wireless communications services, can be used more efficiently.

Ofcom is seeking to understand how enabling more spectrum shared on licensed, licence-exempt and a dynamic-access basis could increase spectrum availability in the future and encourage innovation. As part of this, Ofcom is considering how to best sustain the important role Wi-Fi is already playing in providing wireless connectivity.

These amateur radio bands are mentioned in the consultation – 2.3 GHz, 2.4 GHz, 3.4 GHz, 5 GHz.

AMSAT Wants Amateur Radio Satellites Off US Munitions List

ITARThe ARRL report that AMSAT has asked the federal government to confirm that the Amateur Satellite Service will not be subject to International Traffic in Arms Regulations (ITAR), as a result of export control reforms now underway.

The ARRL news story says:

In May the US Department of State Directorate of Defense Trade Controls (DDTC) proposed changes to the US Munitions List (USML) Category XV (Spacecraft Systems and Related Articles). The changes redefine satellites that would remain under the USML. Satellites removed from USML would be transferred to the Department of Commerce Commerce Control List (CCL).

“We ask that the Directorate of Defense Trade Controls explicitly confirm that satellites, ground equipment, and associated technical data for items pertaining to the Amateur Satellite Service are not subject to the ITAR when the new Category XV provisions are implemented,” AMSAT said in comments filed earlier this month “Over the past 43+ years AMSAT has been integral to the development of Amateur Radio communications spacecraft based upon the model of an all-volunteer organization that follows ‘open source’ practices and creates spacecraft that are very low cost, which also reflects relatively low levels of sophistication compared to commercial satellites,” AMSAT said.

A related set of AMSAT comments went to the Department of Commerce Bureau of Industry and Security (BIS), which has proposed creating a separate CCL category for satellites formerly under ITAR. AMSAT asked that Amateur Satellite Service spacecraft and associated equipment be separately categorized and controlled, given the significant differences between commercial and Amateur Satellite Service spacecraft.

“We ask that the Department of Commerce recognize the relative impacts of regulatory oversight on small, not-for-profit scientific and education organizations such as AMSAT and to find ways to mitigate these impacts on both AMSAT and our volunteers,” AMSAT said. AMSAT suggested creating a separate category for Amateur Satellite Service; allow a license exception for “deemed exports” for Amateur Radio satellite design and construction, to permit a “free exchange of ideas, software, etc pertaining to Amateur Radio satellite design and construction when interacting with foreign nationals who are citizens of nations listed in the License Exception Strategic Trade Authorization Country List, and focus export licensing requirements only on the export of hardware.

AMSAT President Barry Baines, WD4ASW, and AMSAT Congressional Liaison Peter Portanova, WB2OQQ, took on the task of drafting comments in response to a combined 105 pages of bureaucratese drafted by the DDTC and the BIS. Former AMSAT President Bill Tynan, W3XO crafted initial comments as a starting point.

On July 23, 2013 at 1634 UT Mike Rupprecht DK3WN received signals from the UK STRaND-1 satellite after a near four month absence.

Built by volunteers from the Surrey Space Centre (SSC) and SSTL in Guildford STRaND-1 was launched on February 25, 2013 and was the World’s first Smartphone CubeSat to be put into orbit.

Dr Chris Bridges M6OBC and STRaND-1

STRaND-1 unexpectedly stopped transmitting on March 30, 2013 and radio amateurs around the world have been listening for it ever since on a frequency of 437.568 MHz (+/- 10 kHz Doppler).

Radio amateurs are requested to email reports of reception of telemetry data from STRaND-1 to: strand.messages<at>gmail.com

Ham Radio Satellite Operation from Guernsey

Peter Goodhall 2E0SQL operating portable through the satellites

Peter Goodhall 2E0SQL operating portable through the satellites

Peter Goodhall 2E0SQL/2U0SQL will be active on the amateur radio satellites from Guernsey during July 24-30, 2013

On the AMSAT Bulletin Board he writes:

I will be active sporadically on satellite passes from Guernsey (IN89RL) as 2U0SQL.

I shall be focusing on FO-29 [SSB] and SO-50 [FM] passes but no firm pass times, but hopefully will have internet access and will try posting on Twitter (@2E0SQL) when I’ll be on.

Due to this being camping I will be battery powered using a FT-817 and a Arrow antenna.

If anyone needs a QSL Card its direct to 2E0SQL or bureau.
