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 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

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.

JAXA to launch FM voice transponder satellite Diwata-2

Diwata-2 satellite

Diwata-2 satellite

The Philippine Diwata-2 satellite carrying an amateur radio FM transponder and APRS digipeater is expected to launch in October.

The Business Mirror reports:

The 50-kilogram satellite shall soon be sent into orbit by the Department of Science and Technology (DOST) through its partner, Japan Aerospace Exploration Agency (Jaxa).

It should be recalled that the DOST had the Philippines’s first microsatellite—the maiden Diwata-1 that was designed, developed and assembled in Japan by nine pioneering Filipino engineers and scientists along with their “sensei” (instructors) from the Tohoku University (TU) and Hokkaido University (HU).

Diwata-1 was launched into the International Space Station onboard the Orbital ATK’s Cygnus spacecraft on March 23, 2016. It was deployed from the ISS into her orbit on April 27 by the Japanese Experimental Module (JEM)—”Kibo” or Hope—around 400 km above Earth’s surface.

Now, two years and four months later, the government is about to unveil the second iteration of Diwata-1—named Diwata-2 targeted for launching onboard Jaxa’s H-IIA rocket from Tanegashima Island in Japan.

Ariston Gonzalez, a researcher/lead research and development engineer for PHL-Microsat at DOST-Asti, is quoted in the article as saying:

“All one has to do is tune in [a ham radio] to the frequency of Diwata-2 to send voice messages while the other party stands by to receive the voice message.”

“target use for ham radio [of Diwata-2] is for emergency situations wherein all commercial communications are down.”

“What Diwata-2 does is to serve as a relay or connecting point for two persons communicating with each other,” he pointed out.”

“One can also store messages on Diwata-2 that can be broadcasted repeatedly across and over the Philippines, such as prerecorded emergency messages in times of disasters, calamities and other kinds of emergency.”

The IARU has coordinated these frequencies for Diwata-2:
– 145.900 MHz downlink
– 437.500 MHz uplink
