The integration of the LX0OHB-4M amateur radio payload was completed on Sunday night, October 12 and is now ready to launch.

The onboard clock has been adjusted to start JT65B (145.980 MHz) at the UTC minute +/-1 second. It is likely to drift during the mission, and manual offset introduction will be required after a week or so. The launch date is October 23 at 1759 UTC.

Beginning of transmission of 4M will start between 1917 UTC and 1927 UTC. Refer to the provided maps and animations links in the blog section (see also older messages) to determine your visibility. Alternatively, use the ‘tracking’ section where you can compute your tracking elements by introducing your geographic coordinates. The table can be copied/pasted into a text file. As the apparent movement will be close (and closer) to the one one of the Moon, manual pointing is easy but for the largest arrays. We’ll try to publish equivalent TLE’s to input in usual tracking software.

The link budget is quite tight, but the first hours should give comfortable signals. QSB is to be expected.

As JT65B is used: please remind those not yet too familiar with it that the receiver must not be tuned during the transmission. A dedicated webpage is being written to detail the procedure.

A dedicated java application is also available to automatically transmit the decoded messages to the 4M website and ease the data collection. (Thanks to LSE Space). Alternatively, you can also send the decoded messages by eMail, sending the ALL.txt file.

For those not wishing to use JT65B, please record the signals (11025s/s, 8or 16 bits, mono), taking care not to saturate the recording and NO MP3 please.

SpectrumLab is an excellent choice, although some may wish to use simpler recording software.

You can imagine that the team is quite eager to receive the first reports, so, do not hesitate to mail immediately, send decoded messages or even phone or text me at +352 661 678 986.

Our friends of IC CMalaga are also quite eager to receive the results of their radiation dosimeter experiment.

Basic rules of the contest have been delineated in the blog section. Complete rules will be published soon.

Stay tuned on our website or Facebook page.

The following is a tentative set of orbital elements that should remain valid from the launch to at least up to the October 27 when using usual classical and simple tracking software that do not integrate Moon. 1 99999U          14298.79728009  .00000066  00000-0  00000-0 0 00006 2 99999 030.6553 295.6956 9746689 147.2577 071.9585 00.10600338000010 The following set is to be used after the flyby from October 28 onwards 1 99999U          14301.79728009  .00000000   00000-0 00000-0 0 00009 2 99999 049.9434 067.2017 6639865 045.9865 124.5019 00.06612018000010

AMSAT-UK upload JOTA greetings message to satellite

Mié, 10/15/2014 - 12:34

Wouter Weggelaar PA3WEG talking about FUNcube-1 to students at Abbeys Primary School in Bletchley

AMSAT-UK have uploaded a special Jamboree On The Air (JOTA) Greetings Fitter Message to the amateur satellite AO-73 (FUNcube-1).

Scouts and others can receive the message by downloading the Dashboard App software and listening to the beacon on 145.935 MHz (+/- Doppler) SSB.

What is a Fitter Message ?

‘Fitter’ is derived from ‘Twitter’. So it’s like a tweet, but via FUNcube.

It is a short (200 characters maximum) text-like message which can be uploaded to the satellite (by authorised ground stations), and transmitted several times every five minutes or so. It will continue to be retransmitted until such time as it is replaced by a new Fitter Message.
Links for tracking, downloads and other information can be found in the FUNcube-1 / AO-73 panel on the right-hand side of the AMSAT-UK homepage at

From the early planning stage of the project we decided that we would make telemetry information from the AO-73 (FUNcube-1) CubeSat available to end users.

Since deployment the FUNcube Data Warehouse has displayed the latest data:
• Reatime
• Whole Orbit
• High Precision
• Fitter Messages
and of course the upload rankings. Additionally we have made available small csv files for WOD and HiRes.

Starting October 14, we will be making all captured WOD available as weekly csv files.

Please see: for the link to the downloads page. It currently up to 26/6/2014 (32 files)

The files are on average:
• 9706 lines (expected 10080) ~ 96.3% capture
• 905 KB

We will play catch up over the next few days and then automate the process.

It it really intended for consumption by an analytical suite such as MatLab, or a DIY one, in a language of your choosing. However, it can be simply graphed in Excel or Open Office Calc.

Feedback would be appreciated.

New UK Amateur Radio 146 MHz Allocation

Lun, 10/13/2014 - 19:49

The RSGB VHF Manager John Regnault G4SWX gave a key presentation to the RSGB Convention on October 12 about the new amateur radio allocation at 146 MHz.

John said the future use of this band is very much in our hands. If we merely use it for more-of-the-same (conventional modulation and uses) then future use will not be viewed very favourably.

He suggested we should use the band imaginatively, with digital modes and/or new services that would not sit easily within the existing band. Digital ATV with 500 kHz bandwidth, Digital Voice, Spread Spectrum, Data Services along with things not yet widely thought of are the type of activity that is desired.

Developers of wideband modes may face challenges in ensuring their emissions are contained within the new band. Some wideband modes currently used on 1240 MHz have sidebands just 30 dB down that extend over a wide range, this would not be acceptable on 146 MHz.

Bandwidth tailoring will be imperative to ensure no RF extends into the weak signal satellite segment at 145.8-146.0 MHz (the Lunar 4M JT65B beacon uses 145.980 MHz). Narrow band users on 147 MHz must also be protected from any increase in the noise floor.

John asked that those trying new things on the band should report the work they do even if the experiment is a failure. His contact email address is vhf.manager<at>

It may even be that successful exploitation of the new band could lead to further release to amateurs of much needed VHF spectrum!

The new allocation has both Geographical and ERP restrictions. The Ofcom statement on the allocation can be seen at

At the end of October Full licence holders will be able to obtain an NoV for 146  MHz operation from the RSGB online NoV page at


Amateur Radio Licence Review

Lun, 10/13/2014 - 19:00

The Radio Society of Great Britain General Manager, Graham Coomber G0NBI, has issued this statement on the Ofcom amateur radio licence review.

We held our regular meeting with Ofcom last Thursday and, as you will know, Ofcom attended the Convention at the weekend. Feedback from those events is that

• Only 300 or so people have responded to the consultation document so far.
• Ofcom will be relying heavily on the volume and content of the responses as evidence of what the amateur radio community feels about the proposals.

Whilst we published some explanatory notes on the website soon after the document was released, it is apparent that many amateurs have not yet read the document which is far from straightforward in several places.

We are thus today publishing further guidance together with suggested responses to the key questions

There is now just one week before Ofcom’s consultation period ends (20th October) and thus time is of the essence. This note is to ask for your personal support as follows.

Please make sure that you respond to Ofcom.

Please make contact with your club chair (if you belong to a club) or any other amateurs that you are in contact with and urge them to do the same.

Many thanks,

Track of the B-64 balloon

The B-64 balloon launched at 06:51 GMT on July 12, 2014 from Silverstone is still in the air flying at just over 12,000 metres and transmitting on 434.500 MHz Contestia 64/1000 and also APRS.

B-64 envelope – Image credit Leo Bodnar M0XER

On Saturday, October 3 Phil Heron MI0VIM reported decoding data while it was over the North Atlantic ocean, coming up to the 6th time it would pass the United Kingdom on it’s continuing journeys around the world.

B-64 was built by radio amateur Leo Bodnar M0XER, he made both the plastic foil envelope and the solar powered transmitter payload which weighs just 11 grams.

Leo has utilised some clever techniques storing positions when the balloon is out of radio contact then later transmitting a log file of previous locations in the comments field of the APRS packet. This enables a fairly complete path to be built up. B-64 only stores 5 days worth of data, where you get a straight line on the track it has been out of radio contact.

4M lunar ham radio payload shipped

Sáb, 10/04/2014 - 14:10

4M payload under test

Ghislain Ruy LX2RG reports the 4M Lunar flyby amateur radio payload was shipped on Thursday, October 2 and he departs for the Xichang Satellite Launch Center on Sunday, October 5.

He says the lifetime of 4M is quite an unknown: it may be as short as 100 hours (so at least to the Moon) and could extend for some weeks if the attitude is favorable.

It is now known that the spacecraft will not re-enter the Earth atmosphere after the flyby but instead enter a wonderful orbit. You will find information animations and some JT65B test files at

The launch will be transmitted by CNTV/CCTV: or or

LX2RG says the team are setting up their ground station, and are especially looking for southern hemisphere stations: ZS, VK and ZL, Southern America continent mainly, as they will be placed first hand for the early hours.

Launched is planned in a narrow window at 17:59:xx UTC on October 23 and flyby is to occur nominally on October 28 at 00:33 UTC.

4M is planned to start transmissions at 19:17 UTC, possibly with 10 minutes additional delay.

K1JT has developed a special version of WSJT. In addition of all the features of the standard version, it includes also the display and logging of the dT to three decimal places and the logging of the manual offset that can be entered in JT65B modes. This version should be used by all who wants to participate to the ‘Multilateration’ experiment.

The participant to this experiment should also make sure that the clock of their PC stays synchronized to the UTC time. Desired accuracy should be within 1ms and within 10ms at the very least. Use of NTP synchronizing software is a must.

The special version can be downloaded with the following links:

The LuxSpace ground station comprises 2 x 8 element crossed Yagis from Joachims antenna (with an improved design to lower the back lobe), a LNA and Yaesu antenna rotators.

Best regards.

AO-73 (FUNcube-1) – Image credit Wouter Weggelaar PA3WEG

On October 11-2 the Monkton Nature Reserve & Thanet Observatory will be listening to the amateur radio satellite FUNcube-1 and will have an ARDF activity.

On the BIS World Space Week pages they say:

Daytime – we will have solar telescopes to observe the Sun’s surface and prominences. We will have on show the only Solar Ionospheric Disturbance monitor in the United Kingdom which will indicate when the Sun is giving out a solar flare – of huge importance to the communication and navigation satellites in orbit.

The Hilderstone Radio Club will demonstrate the reception of data from the FUNcube satellite in Low Earth Orbit (LEO) giving information on the temperature of its special black and shiny panels in deep space. Using this data visitors can determine the period of its orbit and its speed. They will also demonstrate the reception of weather satellite pictures sent by radio waves to Earth.

We will put on a radio direction finding activity, similar to Geocaching, where visitors have to find hidden transmitters using only a handheld radio and antenna, with a prize for the shortest time.

The club will also set up a special radio station so that visitors can send messages to amateur radio enthusiasts around the world. Information on Space will be provided by the UK Space Agency and worksheets on satellites will be available with questions set by the Nottingham Geospatial Institute.

IARU Administrative Council Plans for WRC-15

Lun, 09/29/2014 - 08:16

The Administrative Council (AC) of the International Amateur Radio Union (IARU) held its annual meeting on September 27-28, 2014 in Albena, Bulgaria. The AC is responsible for the policy and management of the IARU and consists of the three IARU international officers and two representatives from each of the three IARU regional organizations.

Here is a summary of the discussions and actions.

The Council reviewed the IARU positions on each of the WRC-15 agenda items that relate to amateur radio or may have an impact on amateur radio.  The Council made a number of modifications to the paper related to justifications for the IARU positions.  This information will be forwarded to all IARU member-societies.

The Council expressed support for Region 1 in its effort to obtain a CEPT proposal for post-WRC-15 conference agenda items for worldwide harmonization of 160 meters, harmonization of 6 meters and an allocation at 3.4 GHz.

The Council reviewed the participation of IARU at the upcoming WRC-15 and the President announced the members of the team who will represent IARU.

Upon the recommendation of the IARU EMC Coordinator, the Council adopted IARU Resolution 14-1 (“concerning the protection of the radio spectrum as a natural resource”) dealing with EMC issues related to the radio spectrum and which encourages IARU member-societies and regional organizations to pursue implementation of this resolution as a matter of high priority, requests standard-setting bodies and regulators to fully support this objective and implores designers and manufacturers to make every reasonable effort to minimize radio spectrum pollution emanating from their products.

The Council expressed the importance of obtaining the ITU Advance Publication Information (API) numbers from administrations for satellite projects operating in the amateur and amateur satellite bands so that information about the number of operating satellites can be maintained, for frequency coordination and for resolving interference issues.  IARU will work with administrations to establish protocols for satellite frequency coordination and to raise awareness of the satellite regulations.

The Council adopted the IARU Emergency Telecommunications Guide for use by the IARU member-societies to strengthen amateur radio disaster preparedness, response and mitigation.

The Council also adopted various strategies related to improving amateur radio disaster preparedness, response and mitigation and to promote the role of amateur radio in such activities to the general public and to government and non-government organizations.

The Council created the ad hoc “IARU Member-Society Relations Project Team” and adopted Terms of Reference for the project.  This action arose from Minute 10.10 from the 2013 Council meeting Summary Record dealing with “Second Society Issues.”

The Council adopted a system to provide more efficient remote monitoring of certain ITU meetings that may impact amateur radio.

The Plan for the Development of Support for Amateur Radio Frequency Allocations 2012-2017 was reviewed by the Council.  The September, 2013 version of the IARU Spectrum Requirements which is the working document that sets out the spectrum requirements of the amateur and amateur-satellite services, was reviewed, discussed and updated.

The International Telecommunication Union (ITU) meetings at which IARU representation will be required for the remainder of 2014 and for 2015 were identified, and plans for representation at these meetings were reviewed.

In view of the year 2015 being the 150th anniversary of the International Telecommunication Union, the theme “ITU & IARU:  Celebrating 150 years of Advancing the Telecommunication Art” was adopted for the next World Amateur Radio Day, April 18, 2015.

The budget for the years 2015-2017 as presented by the IS was reviewed and adopted. The budget is based upon anticipated financial contributions from the three regional organizations to defray a portion of the expenses, in accordance with previously adopted policy.

The Council received information about the Hamsphere Initiative from Martti Laine, OH2BH.  The Council will review the initiative and seek further information from the project leaders.

The Council was made aware of an ATV interference incident on the 23 cm band in which the German administration prohibited operation of an ATV repeater because of interference to the Galileo GPS system.

Attending the meeting were IARU President Tim Ellam, VE6SH/G4HUA; Vice President Ole Garpestad, LA2RR; Secretary Rod Stafford, W6ROD; regional representatives Hans Blondeel Timmerman, PB2T, Dennis Green, ZS4BS, Reinaldo Leandro, YV5AM, José Arturo Molina, YS1MS, Gopal Madhavan, VU2GMN, Wisnu Widjaja, YB0AZ and recording secretary David Sumner, K1ZZ. Also present as observers were Ramón Santoyo, XE1KK, observer from Region 2 and Don Beattie, G3BJ, observer and President-elect from Region 1.

The next scheduled in-person meeting of the AC will be held in the vicinity of Yogjakarta, Indonesia, in October, 2015 in conjunction with the IARU Region 3 Conference.

RSGB Inspire – Best practice in promoting Amateur Radio

Dom, 09/28/2014 - 19:35

Michael Sansom G0POT brings news of a RSGB focus group seeking best practice when promoting Amateur Radio at special events open to the public. The group aim to share and discuss ideas and experience running Special Events and Demonstrations to members of the public to identify successful approaches to promoting Amateur Radio in the UK.

If you have read page 8 of this months Radcom you will be aware that I am leading an investigation into the experiences and approaches of UK Clubs and Societies when it comes to attracting newcomers to Amateur Radio with a particular focus on running public events.

I am looking for ideas and approaches that are proven to be successful in attracting new Amateurs both young and old. These may include targeting specific events, targeting specific age groups, using specific demonstrations or just the way you engage with the public.

I’ve contacted you as I believe you are a Committee Member with your local club and I would like to publicise the work I’m doing and invite all interested parties to come and join the discussion. I have created a Yahoo group to act as a focal point for sharing thoughts and critiquing ideas. I would be grateful if you could share these details with your Club Members and encourage those with experience and ideas to come and join.

The group can be found by searching Yahoo Groups for rsgb_inspire or following this link:

The research is due to conclude in about 6 months at which time I will report to the RSGB on a portfolio of best practice which can then be shared with Clubs and Societies across the UK. It will also act as a guide to the RSGB where they may be able to support our endeavours to promote Amateur Radio.

If you would like further information including the Terms of Reference for the Working Group then please do not hesitate to contact me.

Many thanks for your support,
Michael (GØPOT)

A replica of the Sputnik 1 satellite

The Secunda Amateur Radio Club will launch two balloons carrying amateur radio equipment from the Vryburg airstrip FAVB on October 4, 2014 at 0600 to 0800 CAT (0400-0600 UT).

This date marks the start of World Space Week 2014. They will commemorate the launch of the Sputnik satellite on October 4, 1957 by attaching an active model replica of Sputnik to one of the balloons. The replica will transmit a Morse code message on 144.076 MHz.

Please e-mail( a screen print of the decoded message with date, time, GPS location, radio and antenna used to receive a special certificate from the launch team, if you are one of the lucky ones that can “decode” by ear please mail above info without the screen print. The transmitter used is a flea power transmitter.

The South African National Space Agency (SANSA) and eight High Schools (80 children) form part of the program. Each school programmed their own data logger with 2 sensors. The 8 data loggers with sensors will be part of the payload of the balloon payload. Each of the school children had to write a Radio Amateur test (10 Questions) as part of their registration and the results will be used to allocated to their final presentation.

There will be a web link with cameras from the launch site atVryburg airport, one camera at Hartbeeshoek and one at Secunda High School. Please send your e-mail info to to get access to the webcams on the internet.

The first balloon will be launched anytime from 0600 CAT (0400 UT) onwards.

The ground stations will use HF on 3.650 MHz or 7.080 MHz or 20m 14.280 MHz between the ground control, chase cars, Secunda High School and Hartbeeshoek. The bands/frequencies may change due to propagation. If your hear the ground stations operate please keep the frequency clear for ground control operations. If you have any feedback in tracking the balloons specifically on descent please report it on the mentioned HF frequencies.

Due to the low APRS Digipeater and IGate density in the Vryburg area radio hams in the adjacent areas are requested to also help track the payloads as well.

It is vitally important to retrieve the payloads since there are data loggers on-board from several schools in the Secunda area. They need the data to complete their assignments.

A High Altitude Glider will also be launched the same morning as the High Altitude Balloon Experiment, HABEX on 4 October 2014.

On the same day at Secunda High School, Secunda, Unisa University will also have a ROBTICS exhibition. SANSA will also have a presentation via the webcam about GPS’s the same day.
