144 MHz Threat: Switzerland’s Ofcom suggest Aeronautical co-primary

QRZ Now - 3 hours 29 min ago

Regarding access by the Aeronautical Mobile Service to the amateur radio 144 MHz band Switzerland’s Ofcom says: ‘a possible so-called co-primary usage between both services could be examined’ 

A report on the USKA site says: 

For us radio amateurs of course this application is a real threat, because we do not see how the amateur radio service with its many powerful 2m stations for DX connections, contests or EME and the service “Aeronautical” could stand side by side on this band without it comes to operating restrictions. The USKA has therefore sent an official letter to OFCOM on 10 July 2019 with our point of view and our concerns regarding the 2m band, as well as other requests related to the WRC 19.

OFCOM’s Head of Frequency Planning has also responded quickly, assuring that it is not a matter of depriving radio amateurs of primary use. However, a possible so-called “co-primary” usage between both services could be examined.

Of course, our goal is to preserve the sole exploitation rights of the 2m band, and we will do our utmost to avert such “co-primary” usage. We are therefore in close contact with the DARC and the ÖVSV.

IEEE Microwave Theory and Techniques Society Seeks Student CubeSat RF Hardware Proposals

QRZ Now - Mon, 07/22/2019 - 6:11pm

The IEEE Microwave Theory and Techniques Society (MTT-S) has announced the MTT-Sat Challenge for groups of students developing RF hardware for CubeSat applications. The MTT-Sat Challenge is a worldwide competition for teams of undergraduate and graduate students to design and build RF hardware for small satellites. The most promising designs will undergo space environmental qualification testing and could be incorporated into an actual CubeSat.

“The main goal of the MTT-Sat Challenge is to advance space RF and microwave education, inspire students to pursue science and engineering education and careers, and prepare tomorrow’s leaders with the interdisciplinary teamwork skills, which are necessary for success,” the society said in announcing the competition. The MTT-Sat Challenge is intended to run over 4 academic years (starting in June 2019) and is divided into several phases spanning overall technology readiness levels. Proposals may be submitted for every single phase.

At this time, IEEE MTT-Sat Challenge is calling for ideas that could come from among the following fields: Transceivers based on commercial of the shelf (COTS) components; antenna systems and arrays for CubeSats; ground terminals for low-earth orbit (LEO) satellites; radiation-hardened electronics based on COTS components; inter-satellite communication; electromagnetic sensors for CubeSats, and novel RF technologies for space applications.

Detailed information is available on the MTT-Sat Challenge. The submission deadline is October 2, 2019, 0900 UTC (October 1, 11 PM HST). Those planning to submit proposals should send a brief letter of interest by August 31.

Two SSTV events during July 29 – August 4

QRZ Now - Mon, 07/22/2019 - 3:42pm

Below is the scheduled (as of July 22) for the planned activation of SSTV from the ISS. The first session is the routine MAI-75 activity that is only active for a few orbits. It appears that the most of the world (except N. America) will get a shot during the two day run. Some lucky operators along the east coast of North America should get a pass on July 29.

Inter-MAI-75 activity

(July 29) GMT 210/13:15  – SSTV activate

(July 29) GMT 210/21:25  – SSTV power down

(July 30) GMT 211/13:50 – SSTV power up

(July 30) GMT 211/19:30 – SSTV shutdown

The second event will be a world wide event running from August 1 through August 4 and will be a memorial event to honor Owen Garriott – W5LFL. He was the first person to operate amateur radio from space. We owe much to his efforts to bring the hobby to space for other operators. The schedule is below  (as of July 22)

ARISS Garriott memorial SSTV activity

(Aug 01) GMT 213/09:40  – SSTV activate

(Aug 02) GMT 214/14:00 – SSTV check

(Aug 04) GMT 216/18:15 – SSTV shutdown

Amateur Radio Being Showcased at 2019 EAA AirVenture in Oshkosh, Wisconsin

QRZ Now - Mon, 07/22/2019 - 2:56pm

ARRL member-volunteers will be part of the excitement as the 2019 International Experimental Aircraft Association annual AirVenture show gets under way this week in Oshkosh, Wisconsin. The show runs from July 22 until July 29. This year marks the 50th anniversary of EAA AirVenture, which drew more than 600,000 visitors and 10,000 aircraft last year. The ARRL exhibit highlights radio communications, encouraging pilots and aviation enthusiasts to discover the many facets of Amateur Radio and to expand their interest in technology. ARRL Product Development Manager Bob Inderbitzen, NQ1R, organized the booth (#2152 in Hangar B) and all-volunteer team.

“This is a great opportunity to show off Amateur Radio at such a large-scale event,” Inderbitzen said. “There’s a kindship among the aviation and Amateur Radio communities. In addition to introducing newcomers to ham radio, we met over 600 ham-pilots at last year’s AirVenture.” (See “Growing Amateur Radio, One Pilot at a Time,” January 2019, QST, pp. 77 – 80.)

Icom America and EAA Warbirds of America have organized special event station W9W, which will be on the air all week from AirVenture. Look for W9W on 40 through 10 meters and on VHF and UHF. The station will be set up against the backdrop of the display of historic and vintage ex-military aircraft.

Members of the Fox Cities Amateur Radio Club (FCARC) are operating W9ZL from the nearby Pioneer Airport. The station is located within KidVenture, which is filled with activities for children and youth attending AirVenture. (See the ARRL Special Events database for further details about W9ZL and W9W.)

Tying in with the 50th anniversary of the Apollo 11 moon landing, EAA AirVenture will host Apollo 11 crew member Michael Collins on Friday, July 26, as the event’s featured guest. Joining Collins during the evening program at Theater in the Woods will be Apollo Program astronaut Joe Engle.

A recent proposal put forward by France at a CEPT pre-World Radiocommunication Conference 2019 meeting targeted a segment of 2 meters, among other VHF spectrum, as a possible Aeronautical Mobile Service allocation, sharing it with Amateur Radio.

According to VERON, an initial Agentschap Telecom response indicated that the French proposal “fits in with Dutch frequency policy” that encourages joint and shared use of spectrum. VERON said Agentschap Telecom has indicated that it’s necessary to take a good look at actual use of the segment and to have insight into compatibility. On July 20, radio amateurs in the Netherlands conducted a 2-meter “propagation experiment” aimed, at least in part, on demonstrating that hams use and need the band.

“VERON shares the opinion that this proposal has no viability,” the organization asserts, pointing to remarks from IARU President Tim Ellam, VE6SH/G4HUA, that the proposal to share 144 – 146 MHz would require 4 years of studies that likely would reach the same conclusion.

UltraLight MLA antenna ver. 4 designed for lower HF bands.

QRZ Now - Mon, 07/22/2019 - 12:29pm
This 4th version of the QRP UltraLight MLA antenna has the same foldable construction designed for easy carry in a common laptop bag same as the 3rd version. This antenna was designed primarily for 40m to 12m bands + CB. Diameter of the main loop growed to 1m and same hight as the ver.3. I have used a wider PVC tubing of foldable boom. All this changes caused higher efficiency on all bands, especially on 40M band which was missing in the 3th version of UltraLight MLA. By using this same variable capacitor I was not able to reach the 10M band. Capacitor is connected in serial fashion because of very low resistance in a whole antenna circuit what is very important to secure a high Q and high efficiency of my loops. I decided to do made 4th ver. because of longlasting poor propagations on higher bands due to a deep Solar minimum in the present years. The tuning box is made of the solid plastic.  For SWR measuring I have used the QRP transceiver XIEGU X5105. The SWR on all bands is better than. 1:1.5 This v. 4 MLA is working from 7MHz to 27,8MHz continuisly and CB band is covered too.  This is the best solution for HAM’s or listeners (SWL’s) who do not have an access to a large space for use a big or long wire antenna. This loop doesn’t need any grounding or counterpoise and work properly also from a very low altitudes. There are many types of this antennas – for 1kW, 100W or QRP power. One of most critical part of this antenna is variable capacitor and the space between it’s plates – bigger space – more power – bigger capacitor – bigger and heavier antenna itself but still good to use as the base antenna. I like hiking, portable or SOTA activities and I needed a small, lightweight (about 960g), compact antenna and easy carryable in a small bag. So I begun to made the UltraLight Magnetic Loops which are completely foldable and very easy to assemble to a fully functional antenna shape just in a 2 minutes! This antenna has also an adapter to mount it on any standard alluminium fishing tripod stand.

Scouts Attending World Scout Jamboree Set to Talk with Space Station via Ham Radio

QRZ Now - Mon, 07/22/2019 - 7:55am

Thousands of Scouts from some 160 countries who will attend the 24th World Scout Jamboree this summer in West Virginia will have the chance to witness an Amateur Radio on the International Space Station (ARISS) contact during their stay. The theme of the World Scout Jamboree, which opens on Monday, July 22, is “Unlock a new world.” If all goes according to schedule, a selected group of Scouts at Jamboree station NA1WJ will pose questions to astronaut Drew Morgan, KI5AAA, at the helm of OR4ISS on the ISS on Saturday, July 27 at around 2:30 PM. Morgan is an assistant scoutmaster. The contact will be enabled via a “telebridge” between NA1SS and ON4ISS at AMSAT-Belgium. The event will be streamed live via Facebook. Work already is under way to assemble NA1WJ for the 11-day Jamboree.

“The station is coming together pretty well, we have most of our advance team here working on antennas, radios, rotators, and all that fun stuff,” NA1WJ Trustee Bill Stearns, NE4RD, told ARRL. He also said that the launch of the first of three APRS-carrying balloons likely would take place today (July 19), with beams for NA1WJ also scheduled for mounting to on-site utility poles, “which means we’ll be into full testing mode for HF starting then,” Stearns said. The balloons are expected to reach 40,000 feet altitude and continue across the Atlantic and perhaps around the world, with tracking via APRS and WSPR. 

In its proposal for the ARISS contact, Jamboree officials said they wanted the ARISS contact to serve as “the pinnacle experience during the World Jamboree,” demonstrating to the nearly some 38,000 Scouts anticipated that “technology is a fascinating vocation as well as avocation and is a suitable area of pursuit within their Scouting program as well as at home when selecting an educational path for their lives and careers.”

The Scouting program embraces a wide range of science, technology, engineering, and mathematics (STEM) activities leading to merit badges in specific fields, including radio.

Scouts will start arriving over the July 20 – 21 weekend. The Jamboree will offer demonstrations of Amateur Radio on HF, VHF, UHF as well as multiple satellite contacts. The Jamboree also will offer Amateur Radio Direction Finding (ARDF) — hidden-transmitter hunts (foxhunting) — on 80 meters and 2 meters. More than 3,000 Scouts are expected to take part in the Amateur Radio demonstrations over the 11 days of the Jamboree, Scout officials said

High school students in Brazil building QO-100 ground station

QRZ Now - Mon, 07/22/2019 - 7:00am

High school students in Brazil are building a ground station for the amateur radio transponder on the QO-100 geostationary satellite as part of a STEM education project.

A group of eight students, from Colégio Embraer Casimiro Montenegro Filho in Botucatu state of São Paulo, are participating in all steps of the project with the help of teachers and amateur radio volunteers from LABRE/AMSAT-BR (Edson PY2SDR, Demilson PY2UEP, José PU2MJR).

The station consists of a 1.2m offset dish antenna, an Amiko L-104 LNBF, a home-made bias-t, a RTL-SDR receiver and SDRsharp software running on a dedicated computer. During the project students were exposed to several STEM topics related to radio communications, antennas, software defined radios, geostationary orbits as well as hand-on activities during the station assembly and configuration.

The students were able to successfully receive test transmissions in morse code kindly made by Roland PY4ZBZ and Fábio PY4AJ. The next step of the project is to introduce digital communication concepts, decode the BPSK engineering beacon and finally to add transmission capability to the station. In the near future, besides making contacts with other stations on QO-100, the students would also very much like to contact other schools and students in the QO-100 footprint.

144 MHz Threat: Disappointing response from Agentschap Telecom

QRZ Now - Mon, 07/22/2019 - 6:50am

The Netherlands communications regulator, Agentschap Telecom (AT), has given a disappointing response to the call by Dutch radio amateurs for the 144-146 MHz band to be protected 

France has submitted a proposal to CEPT for the ITU WRC-23 conference which could see the key amateur band being allocated to the Aeronautical Mobile Service.

The Netherland’s national society VERON reports: 

“In a first response to the letter, Agentschap Telecom indicates that France’s proposal fits in with Dutch frequency policy. The basic principle here is that joint use and shared use of frequency space is encouraged.”

“The NVC (National Preparation Committee) still needs to meet on this to decide on the proposal from France. Agentschap Telecom indicates that it is necessary to take a good look at the actual use and to have insight into the compatibility.”

EME SSTV Lunar Landing Commemorative Event Set

QRZ Now - Fri, 07/19/2019 - 5:07pm

Moonbounce enthusiasts are invited to take part in a commemorative Earth-Moon-Earth (EME) slow-scan television (SSTV) party on 23 centimeters, marking the 50th anniversary of the lunar landing. The event gets under way at 2300 UTC on Saturday, July 20, at PI9CAM in the Netherlands.

“We will start to transmit several lunar landing-related images on 1296.110 MHz,” said the Moon-Net Reflector announcement from Jan van Muijlwijk, PA3FXB, on behalf of “Team PI9CAM.” PI9CAM is the call sign at Dwingeloo Observatory, which boasts a 25-meter dish. “Of course, a bigger antenna is better, but we have had some surprisingly good SSTV reports in the past from moderate-dish stations,” van Muijlwijk said. “Even with a 2.5- or 3-meter dish, you should be able to see some distinguishable images. We also encourage you to try sending some SSTV images yourself.”

He said PI9CAM will coordinate via the HB9Q logger and will be active all night until moonset at Dwingeloo. Team PI9CAM will take time out for two scheduled live, voice moonbounce contacts with Jodrell Bank Observatory in the UK. PI9CAM also will transmit some recorded voice messages. “We hope to see many images off the moon!” van Muijlwijk said.
