The European Student Earth Orbiter (ESEO) satellite carries the AMSAT-UK FUNcube-4 amateur radio 1260/145 MHz FM transponder. On September 27 it successfully completed the vibrations test.

In the past few years, ten student teams from different European universities have combined forces to produce essential equipment for the spacecraft, including subsystems parts, scientific or technology demonstration instrumentation, and the ground mission control support for this micro-satellite mission, planned to fly to Low Earth Orbit later this year.

The project reached an important milestone on August 28, 2018, when the assembly integration of the ESEO spacecraft was declared complete. In this phase all the satellite’s physical parts were assembled together, and all functional interconnections were checked to confirm they work as required.

On September 27, 2018 ESEO reached another key milestone, when it successfully completed the vibrations test campaign at SITAEL’s premises in Mola di Bari, Italy. ESEO has now demonstrated that its design is solid enough to safely withstand the mechanical solicitations it will undergo during the rocket launch.

In the next couple of weeks it will undergo the so-called thermal vacuum and electromagnetic compatibility (EMC) tests at ESA’s ESTEC site in the Netherlands.

FCC 24 and 47 GHz 5G spectrum auction

FCC 24 and 47 GHz 5G spectrum auction

The FCC has announced it is to make additional spectrum available for 5G services by auctioning spectrum that includes 24.25-24.45, 24.75-25.25 and 47.2-48.2 GHz.

The RSGB joint response to the 2018 Ofcom WRC-19 consultation expressed concern about the use of this spectrum.

“the RSGB does not support the allocation of the range 24.25 – 25.25 GHz to the mobile service in Region 1 and its subsequent identification for IMT. The amateur and amateur-satellite services have a global primary allocation in 24 – 24.05 GHz and the out of band emissions from a mass deployment of mobile broadband systems operating in very wide channels in adjacent frequencies will appear as interfering noise in the primary amateur allocation. An identification that starts at 25.25 GHz could mitigate this difficulty.”

“We would not wish to see adjacent out-of-band emissions causing interference to our primary amateur and amateur-satellite service allocations at 24.0-24.05 and 47.0-47.2 GHz”

The rules are simple:

1. Entries must be built from Kits or Home Constructed

2. The judging will take place during in the presentation room during the Lunch breaks on Saturday and Sunday. The entries need only be present for one of these sessions.

3. Three judges, nominated by the AMSAT-UK Chairman, will judge each entry on:

• External Appearance and Ergonomics

• Mechanical Construction

• Standard of Internal Wiring

• Standard of PCBs or internal circuitry

• Originality

4. The winners will be announced at the end of the Colloquium on Sunday afternoon. Prizes will be forwarded if the winner is not present.

5. A £50 Amazon Voucher will be awarded to the winner with a £25 Amazon Voucher for the runner-up.

6. The decisions of the Judges are final, and their marking will remain confidential!

7. Multiple entries for individuals are allowed and encouraged.

The Hindu newspaper interviews radio amateur Gurudatta Panda VU3GDP about the ExseedSat CubeSat built by an eight-person team at the Hyderabad-based Exseed Space Private Limited that was co-founded by Ashhar Farhan VU2ESE.

ExseedSat carries an amateur radio FM transponder and APRS digipeater and is expected to be launched by SpaceX towards the end of 2018.

“This satellite will serve the ham or the amateur radio community. As a result, it will be of great help during natural calamities, when conventional communication services get disrupted,” Gurudatta Panda VU3GDP said.

After the launch, this artificial satellite will be on a polar orbit with two passes over India everyday. The public will be able to receive this artificial satellite’s beacon on 145.900 MHz FM using a TV tuner and USB dongle, Mr. Panda added.

He said the eight-member team involved in construction of the small private satellite involved four technocrats and four managerial staff members.

He and Exseed Space co-founder Ashhar Farhan VU2ESE were the communication engineers who played a key role in building the satellite.

AM1SAT Special Award

AM1SAT Special Award

AMSAT-EA LogoAMSAT EA will be on air on all available satellites with callsign AM1SAT from Sept 10-17 to celebrate IberRadio 2018 – IV Radiocommunications Fair, the biggest HAM party event in Spain and Portugal, Sept 15-16

Main grid will be IN70 but other ones will be activated as well. Our operators will work transatlantic QSOs too. QSLs by LOTW and eqsl

Any questions, please write to contacto@amsat-ea.org

AMSAT-EA will be transmitting its special call AM1SAT via all active satellites from September 10-17 as part of the IV RadioHam Fair IberRadio 2018 activities. IberRadio is the biggest event for the ham community in SouthWest Europe and will open doors September 15th and 16th. AM1SAT callsign will be active from a minimum of 14 different grids during that time to help satellite operators to collect as much EA locators as possible.

As part of this activity and in order to promote the participation, AMSAT-EA is sponsoring the AM1SAT Special Award in two categories: SILVER and GOLD.

AWARD RULES

1. This award can be requested and issued to any licensed amateur station and also SWLs

2. Will be valid contacts all those done via AMSAT satellites from September 10th 2018 to September 17th 2018 in all transmission modes.

3. There are two different requirements to get the awards, depending of the applicant location.

Applicant in a EU entity.

To get the award in its SILVER category, the applicant has to contact AM1SAT in 5 different grids (We consider “grid” as a 4-digits main locator. For example IN71, IM68, JN00, etc). To get the award in its GOLD category the applicant has to contact AM1SAT in 10 different grids.

Applicant in a Non-EU entity.

To get the award in its SILVER category, the applicant has to contact AM1SAT in 2 different grids (We consider “grid” as a 4-digits main locator. For example IN71, IM68, JN00, etc). To get the award in its GOLD category the applicant has to contact AM1SAT in 4 different grids.

4. There is no need of paper QSLs nor EQSLs to ask for the award. When the applicant gets the requirements, s/he has to send via email a log with the QSOs, listing his callsign, name, and QSO data (Date, GMT time, frequencies, mode, received grid and used satellite). Also we need the applicant email to send the award. The awards will be send, latest in 2 months and only in PDF format, free of charge.

5. Logs and any question about this activity must be send to eb1ao@amsat-ea.org

6. Logs must be received by October 1st 2018. We will consider the AM1SAT operators logs as the valid ones to check and cross the QSOs. Disputes or open issues will be solved by AMSAT-EA committee.
