144 MHz band to be used for Commonwealth Games

Ofcom-logo-col-tThe RSGB report that four 25 kHz bandwidth channels in the 144 MHz band between 144.00 and 144.100 MHz will be used at the Commonwealth Games from July 22 to Aug 4.

Following negotiations with the RSGB to minimise the impact on radio amateurs, Ofcom has announced that it will temporarily authorise up to four 25 kHz channels, 144.000, 144.025, 144.075 and 144.100 MHz, for the period July 22 to August 4, 2014, to support the operation of the Commonwealth Games. The frequencies to be used specifically exclude 144.0500 MHz (CW Calling Frequency).

Usage of this spectrum by Commonwealth Games users will be in the vicinity of Glasgow games venues and will be limited to handheld equipment operating on a maximum of 5W ERP. Ofcom emphasises that use of Primary Amateur spectrum is only for the specified time period and does not constitute a change of usage.

Ofcom are aware of the very short notice and will authorise this usage on a “non-interference, non-protection basis”.  Amateurs in the Glasgow area are requested to avoid these frequencies until 4th August.

Goodbye HAMSAT-VO52 – Rest In Peace

HAMSAT VO-52

HAMSAT VO-52

AMSAT-India’s satellite VO-52, launched on May 5, 2005, ceased operation on July 11, 2014. For over 9 years it proved to be a valuable communications resource for the amateur radio community.

Mani VU2WMY posted the sad news:

Dear Friends,

With heavy heart, I sadly convey, that our little angel ‘HAMSAT VO-52’ would no more be able to offer her services to the ‘Amateur Radio Fraternity. HAMSAT VO-52 succumbed in Space on 11th July 2014, while she was on her 49,675th orbit, due to the failure of on-board lithium ion batteries that have met their end of life.

Although her desires were to be at work with other systems and sub-systems working normal as per the latest telemetry received, the on-board computer recurring to ‘Reset’ mode due to the failure of batteries is preventing her to do so.  Hence, it is decided not to expect any more meaningful and reliable services from HAMSAT VO-52.

Since 11th July, every best possible effort has been put in by the spacecraft controllers here in ISTRAC Bangalore to revive her back to life and to help her with work load, so she won’t be swamped when she returns, but with no luck.  Though it is hard, the HAMSAT VO-52 designers and controllers insist that the time has come to let the little angel free in space to go drifting on her own from their care and custody.

Thus, today 21st July 2014, ISRO have decommissioned ‘HAMSAT-VO52′ officially.

We all here in ISRO do definitely hope that ‘HAMSAT VO-52’ worked tirelessly and was a good friend to the ‘Amateur Radio Fraternity’ around the World. We are sure that HAMSAT was loved by all who worked through her. Though, we are deeply saddened by the loss of HAMSAT VO-52, but she will never be forgotten and far from our hearts, minds and memories.

HAMSAT VO-52 will always be remembered by all of us here in ISRO as one of the greatest satellites of ours.

Dear ‘HAMSAT’, looking at the sky, we all say ‘Good Bye’ to you. You’ll be greatly missed. Rest in Peace.

Nevertheless, at this point of time, on behalf of the World Amateur Radio Fraternity, we thank each and everyone who contributed to the great success of ‘HAMSAT’.

Particularly, our sincere thanks to the Chairman ISRO, Dr. K. Radhakrishnan, past chairmen Dr. Kasthurirangan, Dr. G. Madhavan Nair, Director-ISAC Dr. S.K.Shiva Kumar, past ISAC Directors Dr. P.S. Goel, Dr. Shankara, Dr. T.K. Alex, Director-ISTRAC Shri. B.S. Chandrasekhar, scientific secretary Dr. Koteshwar Rao, Project Director-Shri. J.P. Gupta, Deputy project Directors, Mission Director-Shri. R.Suresh, Operations Director-Shri. Parimalarangan and each and every person directly or in-directly contributed.

At this point of time, we also thank AMSAT-India and in particular, lateShri. Nagesh Upadhyaya-VU2NUD,  Shri. B.S. Gajendra Kumar-VU2BGS, Shri. Prathap Kumar-VU2POP, Air Commodore. Subramanian-VU2UV, Shri.  V.P. Sandlas-VU2VP, Dr.R. Ramesh-VU2RMS, Shri. Nitin-VU3TYG, Mr. Williams Leijenaar PE1RAH and each and every member.

Pasted below is the message from Mr. R. Suresh, Mission Director:

HAMSAT, the first small satellite by ISRO has been Decommissioned after nearly a decade of service to the World Ham community.

A true masterpiece among small satellites, designed for one year mission life, but exceeded all expectations by serving for almost 10 years. A truly autonomous satellite, with “Zero maintenance“ in terms of Mission operations, it provided a springboard to test many new concepts such as BMU. LI-ion based power system, automatic Spin rate control and Auto SAOC for maintaining the Satellite attitude without any ground commanding.

HAMSAT known as “OSCAR-52” among the Amateur HAM operators has been very popular because of its high sensitivity receiver and strong transmitter. Indian Radio Amateurs on many occasions conveyed to us that they have been greatly honored to share the adulations showered on ISRO and INDIA by the International Radio Amateur for gifting this wonderful satellite “HAMSAT”.

I take this opportunity to applaud the HAMSAT teams at ISAC, ISTRAC and other centre for their efforts and  support, which has made ISRO proud among the HAM users across the globe.

GB1JSS Summer Solstice: Radio Hams to gather at Galleywood Common

GB1JSS - Galleywood Common, Chelmsford, CM2 8TR

GB1JSS will be active on June 21 from Galleywood Common, Chelmsford, CM2 8TR

Special event station GB1JSS will be active on the amateur radio satellites during the Summer Solstice on Saturday, June 21, the longest day of the year in the Northern Hemisphere. The event is open to all radio amateurs and listeners.

On that day the sun will rise at 04:43 BST (03:43 UT) and set at 21:21 BST giving 16 hours, 38 minutes and 19 seconds of daylight.

CARS-GX0MWT-roundel-badgeMembers of the Chelmsford Amateur Radio Society (CARS) will be operating from Galleywood Common (Grid JO01FQ WAB TL70 Postcode CM2 8TR) for much of the day, subject to weather conditions, the station will be active as early as possible. Planned operating time 9am-6pm.

Steve Hedgecock M0SHQ, who recently gave a well received presentation on satellites at the CARS amateur radio skills workshop, with be bringing his amateur satellite station and hopes to operate as many satellite passes as possible.

They’ll also be a station operating 40m-10m plus 2m using SSB, CW, PSK and RTTY.  The day coincides with the first-half of the 50MHz Trophy Contest, so there may be some 6m activity if conditions are favourable.

Wind-permitting, Peter Bridgeman G3SUY hopes to fly his impressive Kite Aerial and put out a strong signal on 160m using full legal power.

Would you like to operate, help set-up the station or just come along for a visit?

This is a great opportunity to use some of your portable kit at an RF-friendly location or operate one of ours with perhaps more power than your M6/2E licence allows. For more details contact Charlie Davy M0PZT email: m0pzt <at> m0pzt.com

The station will be in the car-park off Margaretting Road next to the Galleywood Heritage Centre.
If you’re coming from Wood Street, just turn right at the Eagle public house and then left at the “P” sign.

There are toilet facilities at the adjacent Galleywood Heritage Centre.

Slow Scan TV (SSTV) images in Scottie 1 format have been successfully received from the amateur radio satellite SPROUT on 437.600 MHz FM (+/- 9 kHz Doppler shift). The Digitalker has also been active.

SPROUT, a 20 x 20 x 22 cm amateur radio nano-satellite with a mass of 7.1 kg, launched successfully with the L-band (1236.5 MHz/1257.5 MHz/1278.5 MHz) Synthetic Aperture Radar (SAR) satellite ALOS-2 on May 24, 2014 at 0305 UT. SPROUT is now in a 654 km, 97.9 degree inclination Sun Synchronous Orbit (SSO).

SPROUT (Space Research On Unique Technology) was built by students from Nihon University and its objectives are:

SPROUT Satellite - Credit Nihon-Univ. Miyazaki Laboratory

SPROUT Satellite – Credit Nihon-Univ. Miyazaki Laboratory

1. Operation of satellite by radio amateurs.

A FM Digitalker will enable the satellite to speak to amateurs around the world.

The Voice Message Box will record transmissions from radio amateurs and play them back.

Pre-loaded images from the Message Gallery can be transmitted using Slow Scan TV (SSTV).

Pictures of the Earth can be transmitted by SSTV and radio amateurs can receive it using free software such as MMSSTV. As part of the Earth mapping project the team ask radio amateurs to contribute pictures they have received from the satellite for display on the SPROUT website.

The satellite also has a packet radio Digipeater and Text Message Box function.

SPROUT in orbit2. Demonstration of the deployment of the combined membrane structure and verification of the design method of the structure SPROUT has a triangular membrane supported by two tubes like framework. They are folded and stored in the satellite before the launch. After the launch, the nitrogen gas is injected into the tubes in space, and they extend, so that the membrane deploys (called “combined membrane structure”).

3. Demonstration of attitude determination and control of a nanosatellite using the sun sensors, gyros, geomagnetic sensor and magnetic torquers.

Shin-En2 Satellite Linear Transponder Frequencies

Shin-En2 satellite

Shin-En2 satellite

The IARU Amateur Satellite Frequency Coordination Panel has announced frequencies for the Shin-En2 linear transponder.

Shin-En2 is a 2.85 kg satellite measuring 490×490×475 mm built by students at Kagoshima University in Japan which will carry a 145 to 435 MHz linear transponder into a deep space orbit.

The aims of the mission are:
• To establish communication technologies with a long range as far as moon.
• To establish a new technology of the ultra-light-weight satellite. Proposing a WSJT 29dBm UHF downlink and a 29dBm 20 kHz linear transponder and a CW beacon all on UHF with a VHF uplink for the transponder

The orbit will be quite different from the previous satellites. Shin-En2 will have an elliptic orbit around the Sun and travel to a deep space orbit between Venus and Mars. Its inclination will be almost zero, which means Shin-En2 will stay in the Earth’s equatorial plane.

The distance from the Sun will be between 0.7 and 1.3 AU. An Astronomical Unit (AU) is 149,597,871 km.

Shin-En2 IARU coordinated frequencies:
• 437.505 MHz CW beacon
• 437.385 MHz WSJT telemetry
• Inverting SSB/CW transponder
– 145.940-145.960 MHz uplink LSB
– 435.280-435.260 MHz downlink USB

Shin-En2 is expected to launch in the 4th quarter of 2014 with another amateur radio satellite ARTSAT2:DESPATCH on a H-IIA rocket with the asteroid explorer Hayabusa 2 as the main payload.
