Dave says: “It started with a call from a TV production company who were working on a series for Heston Blumenthal. They’d heard that I fly the Raspberry Pi and wanted to include it in their Pie episode. The idea was to fly a potato as that was the first vegetable to be grown in space.”

The show Heston’s Great British Food was broadcast on Channel 4 on Thursday, May 1. You can watch it online during the next few days at

The Spud in Space segment starts at about 24:38 into the show.

Dave is well known for his balloon flights using the Raspberry Pi computer board. On July 14 2012 Dave, then M6RPI, built and launched PIE1 from Brightwalton, in Berkshire. The images taken by the camera were transmitted in the amateur radio 70cm band (434 MHz) using the Slow Scan Digital Video (SSDV) standard, see
https://amsat-uk.org/2012/07/17/pie1-raspberry-pi-sends-live-images-from-near-space/

His next flight will take place on Sunday, May 4 at around 6:30pm BST and aims to capture the sunset with some new cameras.

The two trackers are:
PIE – 434.650 MHz, 300 baud, 750Hz shift, 8, N, 2.  Telemetry and SSDV.
BUZZ – 434.600 MHz, 50 baud, 460Hz shift, 7, N, 2.  Telemetry only

There will be one or maybe two BATC video streams:

Expected flight profile is burst alt 30km ascent 5m/s descent 5m/s. Landing spot NW of Cheltenham.

AMSAT-India VO-52 completes nine years in orbit

HAMSAT VO-52

HAMSAT VO-52

On Monday, May 5, 2014 AMSAT-India’s VO-52 will have completed 9 years in orbit. During this time it has proved to be a valuable communications resource for the amateur radio community.

Mani, VU2WMY, posted this on the AMSAT Bulletin Board:

It gives us great pleasure to inform that ‘HAMSAT – VO-52’ is successfully completing 9 years of fruitful services on 4th May 2014 and entering into her 10th year of services on 5th May. HAMSAT was launched as a piggy back aboard PSLV-C6 on 5th May 2005 (5-5-5). We do hope that the contribution of ‘HAMSAT’ by India/ISRO to the ‘Global Amateur Radio Fraternity’ has served its purpose. It gives us great pleasure and satisfaction to note that ‘HAMSAT VO-52’ has remained as one of the most sought after and favorite ‘Linear Birds’ among the radio amateurs for her sensitivity, strong down link signals, stability and the ease to work.

Though expected to work for two years (mainly, considering the battery), HAMSAT VO-52 has really out lived and still doing strong. Latest telemetry indicates all the parameters and systems to be normal and satisfactory. We do hope that ‘HAMSAT’ would continue to provide her good services to ‘Amateur Radio fraternity’ for many more years.

On this happy occasion, we place on records our sincere thanks and appreciations to, Chairman ISRO, Scientific Secretary ISRO, Director ISRO Satellite, Mission Director, Operations Director, ‘HAMSAT’ project team at various ISRO centres, AMSAT-India and Williams Leijenaar PE1RAH  for their contribution in achieving this this milestone.

Ofcom: Statement on Spectrum Sharing

Ofcom-logo-col-tOfcom has published its Spectrum Management Strategy and Statement on Spectrum Sharing.

The Spectrum Management Strategy sets the strategic approach and priorities for managing radio spectrum.

As the intensity of spectrum use increases, with greater levels of sharing between different uses, managing the co-existence between services will become more important. Ofcom’s strategic approach relies on market mechanisms where possible and effective and on regulatory action where necessary. It also places increased emphasis on:

• exploring opportunities for new types of spectrum sharing;
• managing the co-existence of different services and by promoting technology improvements that minimise interference;
• providing more information on how spectrum is used in the UK. As part of this, Ofcom has published today an interactive spectrum map providing easy-to-access details on how different frequencies are used in the UK; and
• leading discussions on international spectrum issues.

Six priorities for spectrum management

Ofcom has identified six priority areas for future spectrum use. They are:
1. Future mobile data demands: Ofcom will consider the potential impact these demands have on other users of spectrum. Ofcom will also contribute to international decisions, examine in detail the case for using more spectrum for mobile data, support improvements in mobile coverage and monitor developments towards 5G technology.

2. The future of the 700MHz band and free-to-view TV: Ofcom is investigating the potential to rearrange the bands used for digital terrestrial TV. This could release more of this prime spectrum for mobile broadband use sometime after 2018, while ensuring that viewers would continue to benefit from digital terrestrial TV.

3. Public sector spectrum release: Ofcom will support the Government in achieving its target to release 500 MHz of spectrum from the public sector. A first step will be the release of spectrum at 2.3 and 3.4 GHz, currently held by the Ministry of Defence.

4. Programme Making and Special Events: Ofcom is working with PMSE stakeholders to understand their current and future spectrum demands for wireless microphones and cameras.

5.Machine-to-Machine applications: Ofcom has started work to understand the implications of the expected growth in M2M. Enabling licence exempt access to the 870-915 MHz band is a first step towards ensuring spectrum availability to support innovation in this area. The UK is among the first countries globally to release spectrum that can support M2M communications.

6.The emergency services: Ofcom will support the Government is assessing how best to deliver the wireless communications needs of the emergency services over the long term.

Encouraging the wider use of spectrum sharing

In the UK, half of all adults own a smartphone and one in four households has a tablet computer, fuelling a surge in demand for more data capacity. Meanwhile, research commissioned by Ofcom found that by 2022 over 350 million additional devices in the UK – including cars, crop sensors and washing machines – are also likely be connected to the internet, many using tiny slivers of spectrum.

To help meet this demand and building on our existing work to open up TV white spaces for use by a range of innovative services, Ofcom has identified three key areas where spectrum sharing can play an important role:

• for indoor use: by continuing to provide high speed wireless network connectivity to ensure that consumers can fully benefit from the increasing availability of superfast broadband;
• for outdoor use: by increasing the supply of spectrum for use by a growing number of small mobile broadband cells, which are being deployed to help meet the growth in demand for mobile data capacity driven by the increasing use of smartphones and tablets; and for
• the internet of things (IoT) use: by helping provide the spectrum needed to support growth and innovation in the emerging IoT sector, which is set to see hundreds of millions of devices become wirelessly interconnected by the end of the decade. These new services have the potential to provide benefits across a wide range of sectors, including healthcare, energy distribution, transport and agriculture.

LituanicaSAT-1 Camera and FM Voice Transponder

LituanicaSAT-1 Camera and FM Voice Transponder

The LituanicaSAT-1 team have provide a further update on upcoming operation of the CubeSat’s FM transponder.

LituanicaSAT-1

LituanicaSAT-1

Dear amateur radio operators,

The LituanicaSAT-1 FM transponder is scheduled to be operative again on May 1, from 9:30 UT to 14:00 UT.

Satellite’s ground control station in Vilnius will be monitoring the transponder’s frequency and attempt to call CQ with the amateur call sign LY5N (LituanicaSAT-1 callsign) when the satellite will be in sight of the ground station. The expected time windows are:

* 2014/05/01 10:46:22 UT – 2014/05/01 10:56:24 UT
* 2014/05/01 12:21:48 UT – 2014/05/01 12:31:47 UT

LituanicaSAT-1 FrequenciesAll QSO’s with the call LY5N will be granted special QSL cards, signed by the LituanicaSAT-1 core team members and sent out via bureau (no directs).

Every amateur working the FM repeater is encouraged (but not obligated) to RX and answer only the LY5N CQ call during the above time windows.

73,
LituanicaSAT-1 team

Frequency are approximately 435.1755 MHz for the downlink and 145.950 MHz for the uplink (+/- Doppler Shift).
