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.

Masa JN1GKZ reports JAXA has announced three CubeSats, Irazu (Costa Rica), 1KUNS-PF (Kenya) and UBAKUSAT (Turkey)  will deploy from the International Space Station on Friday, May 11 between 1030-1040 GMT.

All the CubeSats carry amateur radio payloads, Irazu and 1KUNS-PF have telemetry beacons while UBAKUSAT carries a linear transponder for amateur radio SSB and CW communications in additional to CW and telemetry beacons.

The deployment will be broadcast live on YouTube, watch from 1000 GMT Friday, May 11.

Irazu is a 1U CubeSat developed by students at the Costa Rica Institute of Technology
Telemetry Beacon 436.500 MHz

1KUNS-PF is a 3U CubeSat developed by students at the University of Nairobi
Telemetry Beacon 9600bps 437.300 MHz

UBAKUSAT is a 3U CubeSat developed by students at the Istanbul Technical University
CW Beacon 437.225 MHz
Telemetry Beacon 437.325 MHz
Linear Transponder
• 435.200-435.250 MHz downlink
• 145.940-145.990 MHz uplink

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,

Emily Calandrelli KD8PKR with her new Ada Lace book

Ada Lace, Take Me to Your Leader is a new book written for young people by Emily Calandrelli KD8PKR that features amateur radio and space communications.

Ada is an 8-year-old with a knack for science, mathematics, and solving mysteries with technology. Her latest project is to fix up a ham radio, something that she could use to contact people on this planet and beyond.

The book is available on Amazon at http://amzn.to/2DbKt9L

Unicorn-2a in Space – image credit Alba Orbital

Glasgow-based Alba Orbital plan to launch a 3p PocketQube Unicorn-2a built by several radio amateurs including Constantin Constantinides MM6XOM, Sajimon Chacko 2M0DSY and Alejandro González Garrido EA7KDU. A 3rd quarter 2018 launch is planned on a Vector Launch Inc. rocket from Kodiak, Alaska into a 350 x 350 km 98 degree orbit. The mission will last about 45 days and Delfi-PQ is expected to be a fellow passenger on the launch.
