The JOTA-JOTI FUNcube Challenge

AMSAT-UK FUNcube Mission Patch Rev4 20100609

AMSAT-UK FUNcube Mission Patch

In space, satellites can be found. A recent development in this area are the “CubeSat” satellites.

Normal satellites typically have a size ranging from that of a washing machine to a small truck.

CubeSats have the size of a milk-carton!

The JOTA-JOTI FUNcube Challenge focuses on the FUNcube-1 (AO-73) CubeSat satellite. During the Jamboree On The Air (JOTA-JOTI) on October 19-21, a special, coded, message will be transmitted. This message can be received with a simple 2m handheld antenna, e.g. HB9CV, a small yagi or even a vertical, and a SDR-dongle or any SSB radio for 2m. The data is sent by the satellite on its telemetry channel of 145.935 MHz (1200bd BPSK modulated). You will need to set your receiver to Upper Side Band (USB). If you use a FUNcube dongle, you can directly receive the satellite.

The message is coded using the Enigma cipher machine. The deciphering key and Enigma settings can be obtained by answering the questions below.

The message sent by the satellite follows the following format: JOTA JOTI START coded message STOP

Your deciphered message can be mailed to: JJ.Satellite.Challenge (at) kitbuilding.org ( (at)=@)

The mail should contain your name, age, country and Scout group name and the correct answer!

If you have any pictures of the reception of the satellite with your group, this would also be highly appreciated, we would love to see how you did it!

If your answer is right and mailed before the 1st of November 2018, you will participate in a raffle.

The winner will get some products from www.kitbuilding.org
Have a lot of fun and good luck! Best 73s, Wouter PA3WEG and Jeroen PE1RGE

FUNcube-1

As you will know, AO73/FUNcube-1 has been in full sunlight for over one month and has been transmitting continuously high power telemetry for most of that time. This has now been changed to full time amateur mode so the transponder is once again available. With the more stable on board temperatures being experienced, this means that the transponder frequencies are also now more stable. We expect to leave it in this mode for some weeks so that the team can determine whether or not the currents flowing from the solar panels are having any noticeable effect on the spin period.

FUNcube-2

The FUNcube-2 transponder on EO-88/UKube-1 continues to be in full time transponder mode. There are occasional breaks in service for a few seconds when the OBC reboots and the other onboard transmitter sends its CW beacon.

FUNcube-3 on Nayif-1

EO88/Nayif-1 continues to perform nominally with high power telemetry when in sunlight and amateur mode when in eclipse.

With their slightly different orbital characteristics it is useful that AO73 is now the early bird, EO88 comes over in the mid morning and UKube provides coverage in the afternoon.

We have been suffering from some network issues in relation to uploading the telemetry from the Dashboards to the Data Warehouse over the past couple of weeks. Apologies for this, but hopefully everything is now stable again. ie fingers are still crossed. Thank you for all the telemetry that you upload.

Like many other teams, we are presently waiting for the next Space-X launch from Vandenberg which is expected to be carrying a number of new amateur payloads, These will provide additional transponder and STEM capabilities for the amateur satellite service. Exciting times ahead.

Cassini-Huygens: Odyssey to Saturn and Titan – Sunday Oct 14

Professor David Southwood

Professor David Southwood

At 10:45am on Sunday, October 14, the Chair of the UK Space Agency Steering Board Professor David Southwood will give a presentation on the Cassini-Huygens mission to the AMSAT-UK International Space Colloquium in Milton Keynes.

More than 35 years ago, a small group of scientists in Europe met with American counterparts to discuss what might be done to explore jointly the outer planets – in particular Saturn, its rings and moons.

At the time, Europe did not have plans to explore the solar system at all. Indeed, many wanted to keep it that way. Nonetheless, in what seems now a very short time, 6 years later, it was agreed that Europe and the US would jointly perform a grand mission, Cassini-Huygens to Saturn and its major moon, Titan with Europe building Huygens, the Titan lander.

In 2017 almost 20 years after Cassini-Huygens was launched to Saturn the programme finally ended with the Cassini mothership deliberately diving into the Saturn atmosphere. The history of the programme and some of its highs and lows will be outlined.

The AMSAT-UK Colloquium is part of the RSGB Convention at the Kents Park Conference Centre, Timbold Drive, Milton Keynes, MK7 6BZ. Colloquium presentations will be in Lecture Room 5. Download the programme schedule from

New amateur satellite forum aims to help newcomers

Peter Gülzow DB2OS President AMSAT-DL

Peter Gülzow DB2OS President AMSAT-DL

AMSAT-DL President Peter Gülzow DB2OS reports on a new amateur radio satellite forum that aims to help newcomers become active on the satellites.

On the AMSAT Bulletin board (AMSAT-BB) he writes:

We have set up a new online forum at https://forum.amsat-dl.org/

Especially with the upcoming launch of P4-A / Es’hail-2 we want to offer a forum for extensive discussions.

Essentially this is a forum, where everyone can report on experiences and knowledge from operating satellites and thereby help other newly interested radio amateurs to become active and a member of our satellite community.

Of course all topics around amateur radio satellites and OSCAR’s should be discussed there, appropriate categories and forums were created. If necessary this can be extended at any time and on request.

We would be pleased if the new forum is well received and you register there with your callsign (if available) as your name.

Of course you can also look around as a “guest”.

Experienced users can also check in the settings for new entries and have them delivered by eMail if you wish so.

In this sense, have fun
