Bulgarian CubeSat EnduroSat on ISS awaiting deployment

EnduroSat One

EnduroSat One

Bulgaria’s first CubeSat, EnduroSat One, was launched to the International Space Station on the cargo resupply OA-9 mission on May 21, 2018 from the Mid-Atlantic Regional Spaceport in Virginia, USA. On May 24 the Cygnus capsule docked to the Station and the satellite was taken onboard the ISS.

The satellite will be deployed from the ISS in the coming weeks.

The mission aims to popularize the Radio Amateur activities in Bulgaria and it will include cooperation with Bulgarian Federation of Radio Amateurs (BFRA), including workshops and additional educational activities.

The spacecraft has been completely built in Bulgaria. This first educational mission aims to inspire young Bulgarians and give them the chance to participate in a real space program!

The Space Challenges and EnduroSat teams have invested considerable resources, time and effort in preparing the Bulgarian CubeSat. In order to support the Radio Amateur community, the satellite emits in frequencies which are readily available for receiving by anyone with basic communication skills and radio equipment.

It is hoped the mission will help more young Bulgarians learn the basics of satellite communications through practical exercises empowered by the orbiting satellite.

Radio amateurs from around the Globe will be able to listen to the satellite beacon and to receive telemetry data from the satellite on a regular basis. They will be able to connect to the satellite, receive detailed telemetry information and receive a confirmation from the satellite for every established connection which will serve as QSL card.

Beacon: 437.050 MHz CW and 9600 bps GMSK AX.25

IARU R1 highlights threat to higher ham radio bands

In issue 77 of the free IARU Region 1 VHF newsletter the Chair of VHF-UHF-uW committee Jacques Verleijen ON4AVJ highlights the threats to vital amateur radio spectrum at VHF, UHF and Microwaves.

In less than a year we will have our interim meeting about the use of the spectrum above 30 MHz. We have to face some challenges. I want to invite all Member Societies to think about how to promote, defend and use our frequencies.

They are wanted by others, both government and commercial, users. So this is a wake-up call to be aware that if we not are using those bands we will lose them. Such a setback will not be the responsibility of IARU(R1), if we lose them, but from the amateur community who often have more commitment to HF, than VHF&up.

I know that this statement will shock some of you, but it is true. Our survey on the use of VHF&up made this clear. So I want to invite all Member Societies to think creatively (out of the box, as we say now) to think how to improve activity on our dear bands.

Like some have said: “use them or lose them” and “HF is not the only bands for ham radio, but they are the easiest to use”.

DSLWP is a lunar formation flying mission led by Harbin Institute of Technology for low frequency radio astronomy, amateur radio and education. It consists of a pair of 47 kg microsatellites, to be launched into a lunar transfer orbit UTC this Sunday evening, and finally enter a 300 x 9000km lunar elliptical orbit. Onboard each satellite, there are two VHF/UHF SDR transceivers to provide beacon, telemetry, telecommand, digital image downlink and a GMSK-JT4 repeater. Onboard transmitting power is about 2 W.

Wei Mingchuan BG2BHC reports the satellites are 50x50x40 cm with a mass of about 45 kg and are 3-axis stabilized. Two linear polarization antennas are mounted along and normal to the flight direction.

Harbin Institute of Technology Amateur Radio Club expects radio amateurs to join in this mission. We will prepare different QSL cards for different flight phase for amateurs successfully made QSO or received telemetry. Awards will also be given to the first 10 amateurs in each continent who successfully decoded the signals from the satellites, received the most number of packets, or received an image. Your participation will also help the team to get a better knowledge of the status of the satellites.

An open source decoding software based on GNU Radio to work with RTL-SDR and USRP is provided. Not difficult to change the grc files to support other SDR receivers. A small proxy software will send the decoded data to a server for real-time display.

Amateur satellite operation from Isle of Islay

Camb-Hams 2018 Isle of IslayThe AMSAT News Service reports members of Camb-Hams operating GS3PYE/P will be active on the amateur radio satellites from the Isle of Islay between May 13-18.

The Camb-Hams have been activating the Scottish Isles each year since 2008. As in the past, ten or more operators will be active on all bands and many modes from 4m to 80m, 2m & 70cm for Satellites and 2m & 23cm for EME.

The HF bands will be covered by four simultaneous stations while the 6m & 4m stations will have a great take-off towards the UK and Europe. All stations will be able to run at the full UK power limit. EME operations will use 150W to 55 elements on 23cm and 400W to 17 elements on 2m, primarily on JT65, but also available for CW skeds – if your station is big enough. Satellite operations on 2m & 70cm will use X-Quad antennas and a fully automatic Az/El tracking system.

Activity is planned on AO-7 (mode B), VO-52, FO-29, SO-50 & AO-73.

Most importantly, this is a group of good friends doing what they enjoy, so please give them a call and enjoy the trip with them. They will be active on the major social networks before, during and after the trip, you can check on their progress and interact with the operators via their blog or through Twitter, Facebook and YouTube [see links below]. Please check their Web page for details on how to arrange skeds on the more challenging bands, modes, VHF and EME.

Additional Spectrum in EI – Clarification from IRTS

Frequency Table

Frequency Table

The very welcome announcement of the massive allocation by ComReg of low-band VHF spectrum to the Amateur Service raised some questions about the wording in the document.

Seán Nolan EI7CD, IRTS/ComReg Liaison, has kindly provided this clarification:

The use of AMSAT in ComReg Document 09/45 R4 is regrettable and is a legacy issue carried forward from earlier versions of the Amateur Station Licence Guidelines. Most of ComReg’s documents are commercially sensitive and no draft documents (other than consultations) are published. Although documents relating to amateur radio are not commercially sensitive we do fall under the non-publishing of draft documents embargo.

The use of AMSAT somewhat randomly confuses the actual situation regarding satellite operation. The frequencies in Annex 1 of the Guidelines are available to all CEPT Class 1 and Class 2 licensees. So far as satellite operation is concerned amateurs here can use the satellite segments mentioned (435-438 MHz; 1260-1270 MHz: 5650-5670 MHz –uplink and 5830-5850 MHz –downlink). The “All modes” in the Modes column in Annex 1 covers the relevant operating mode for the satellite concerned. Similarly 10450-10500 MHz can be used for satellite communications.

In the Modes column of Annex 1, all modes are indicated. In many cases “including digimodes” is stated but of course ‘all modes’ includes digimodes. In the definitions in Annex 1 digimodes are defined as “Any digital mode such as —–“. So DSTAR, DMR etc would be included.

We will of course work with ComReg to secure additional spectrum and facilities. The present initiative by ComReg is as a result of such work by IRTS. In this context we would hope in the future to get 2400-2450 MHz among the bands on general release.

Finally some people are wondering why we didn’t get 52-54 MHz. We have of course been seeking this. However, as you know the question of granting 52-54 MHz to Region 1 of the ITU to align with ITU Regions 2 and 3 is the subject of Agenda Item 1.1 of WRC-19. ComReg will be involved in in seeking to establish a CEPT Common Position and so will not move on it before WRC-19. If the IARU WRC-19 initiative is not successful we will seek a national allocation at 50-54 MHz under Article 4.4 of the ITU Radio Regulations.

I realise that the somewhat random use of “AMSAT” and the use of “All Modes” in some places and “All modes including digimodes” in others can lead to confusion. I hope my attempt to ‘clarify’ helps.

Best regards,

Seán Nolan EI7CD
IRTS/ComReg Liaison
