OSCAR 100

AMSAT has now granted OSCAR status to 100 Amateur Radio satellites. The latest, Es’hail-2/P4A — now Qatar-OSCAR 100 (QO-100) —launched from Cape Canaveral, Florida, in November. It carries the first geosynchronous Amateur Radio payload. Es’hail-2/P4A was developed jointly by the Qatar Amateur Radio Society (QARS) and Es’hailSat (the Qatar Satellite Company), with AMSAT-DL as the technical lead. Now at its final position of 25.9° E and with the narrow and wideband transponders having been successfully tested in December, the transponders are expected to be opened for general use this month. “May the 100th OSCAR satellite be the guide star to future Amateur Radio satellites and payloads to geostationary orbit and beyond,” invoked Drew Glasbrenner, KO4MA, AMSAT Director of VP Operations and OSCAR Number Administrator. — Thanks to AMSAT News Service

Cuban Radio Amateurs Respond to Severe Tornado

QRZ Now - Mon, 02/04/2019 - 6:30pm

From the early morning of January 27, radio amateurs in Cuba’s capital of Havana were keeping an eye on the weather. An extratropical low-pressure system in the southeastern Gulf of Mexico associated with a cold front approaching from the west was preceded by a line of pre-frontal storms, generating severe weather conditions that deteriorated considerably during the evening and night hours. Completely unexpected was an F4 tornado that caused considerable damage in Havana. While hurricanes and tropical storms are fairly regular occurrences, the tornado was reported to be the first ever to hit Havana.

“Once again, Amateur Radio operators proved how they could handle emergency traffic during the severe weather event, when the 2G and 3G mobile cellular phone systems collapsed due to damage and the excessive traffic generated by the event,” Radio Havana’s Arnie Coro, CO2KK, reported on his DXers Unlimited, Weekend Edition program. “Using the Havana Metropolitan Area main repeater on 145.190, stations with handheld FM transceiver[s] could keep in touch from even the most difficult places in the affected areas comprising the municipalities of Regla, San Miguel del Padrón, Habana del Este, and 10 de Octubre.”

According to media reports, the storm, with winds approaching 260 MPH, left at least six dead and more than 200 injured; damage to homes and buildings was substantial. The severe weather also took out electrical power lines and utility poles in various areas, leaving much of Havana in darkness and disrupting wired and wireless telephone systems.

A Havana repeater on 145.33 MHz was pressed into service for the first time for this sort of event. A 144.410 MHz repeater in the affected area of 10 de Octubre proved very useful in handling traffic with medical workers, firefighters, and government emergency managers, Coro said in his broadcast.

More than a dozen radio amateurs responded to assist in the weather emergency, handling message traffic, a Federación de Radioaficionados de Cuba (FRC) report said. “It is worth mentioning the speed with which the emergency information was handled via radio, since everything happened so fast, complicated by a lack of electrical power, land-line, and cell communication. [E]verything was in chaos. In seconds, everything stopped working,” the report added.

While power and telecommunications were promptly restored in many areas, repair or replacement of homes, buildings, and infrastructure lost in the severe storm will take a lot longer.

“At times like these, it can be said, radio amateurs are useful for the benefit of society,” the FRC report said.

ARISS / NOTA Slow Scan TV Event, February 8-10

QRZ Now - Mon, 02/04/2019 - 5:06am

ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events. Transmissions are scheduled to begin Friday, Feb. 8 at 18:25 UTC and run through Sunday, Feb. 10 at 18:30 UTC.

SSTV operations is a process by which images are sent from the International Space Station (ISS) via ham radio and received by ham operators, shortwave listeners and other radio enthusiasts on Earth, similar to pictures shared on cell phones using twitter or instagram.

When this event becomes active, SSTV images will be transmitted from the ISS at the frequency of 145.80 MHz using the SSTV mode of PD120 and can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver the covers the 2 meter ham band. After connecting the audio output of the radio receiver to the audio input of a computer running free software such as MMSSTV, the SSTV images can be displayed.

Transmissions will consist of eight NASA On The Air (NOTA) images see 
https://nasaontheair
.wordpress.com/
 ,
In addition, four ARISS commemorative images will also be included.

Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware
.com/ARISS_SSTV/index.php
 .
In addition, you can receive a special SSTV ARISS Award for posting your image. Once the event begins, see details at https://ariss.pzk.org.pl/sstv/ .

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time.

Please check for news and the most current information on the AMSAT.org and ARISS.org websites, the AMSAT-BB@amsat.org, the ARISS facebook at Amateur Radio On The International Space Station (ARISS) and ARISS twitter @ARISS_status.

About ARISS

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in space (CASIS) and National Aeronautics and Space Administration (NASA).

The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

Cory Gibson, W3CDG and Tim Duffy, K3LR discuss the new DX Engineering Radio RF Ground Plane Kits.

QRZ Now - Fri, 02/01/2019 - 9:29am

DX Engineering Radio RF Ground Plane Kits provide an effective method of reducing stray RF pickup by equipment and interconnecting cables. Used under and in back of equipment, this 1/16 inch thick, pre-drilled copper sheet creates an RF reference plane that is typically connected to the existing grounding bus. As described in the ARRL’s “Grounding and Bonding for the Radio Amateur” by H. Ward Silver, N0AX; a large surface area of metal improves upon the single conductor grounding buss by equalizing the RF E-field (electric field) around equipment and attached cables. This reduces voltage differences between pieces of equipment and the associated currents that cause RF interference to transceivers, microphones and accessories. The reduction in RF interference improves both transmitted and received signal quality.

The Radio RF Ground Plane Kits are available in six versions, displayed below; three sizes of copper plate with hardware and the same three sizes copper plates with companion mounting boards made of Medium Density Fiberboard (MDF), with hardware. All kits are intended for indoor use only.

As used by top contesters and DXers alike, a flat metal sheet placed under equipment, along with physically short grounding braids, wires and interconnection cables can significantly reduce the RF voltage differences between cables and equipment. The chance of RF trouble in your equipment is reduced by installing DX Engineering Radio RF Ground Plane Kits in your station.

Field Testing The MFJ Octopus Antenna | Did It survive the wind?

QRZ Now - Fri, 02/01/2019 - 6:32am

“This time, I’m out in the field (way out in the Arizona desert) Field testing the MFJ Octopus antenna. So how does it hold up in 60 MPH winds, harsh desert environments and portability as a quick setup field antenna system. I used this antenna all week with my Icom IC-7300 and my Xeigu X-5105.”

Octopus antenna hub turns your ham-sticks into four fully balanced dipoles in minutes!

Mix and match any four HF/VHF/UHF bands.

Example: screw in 80,40,20 meter hamsticks and a dual band 2M/440 MHz whip (two on each band) on opposite sides. Now you have an automatic bandswitching 5-band dipole! Rotate it for maximum signal and minimum QRM and noise with a small rotator like Hy-gain AR-500, $129.95.

Works at any height, low for local NVIS and high for DX. At a fixed height, (say 20-30 feet) use 80-Meters for NVIS and 20-Meters for low-angle DX.

Mounts on any mast up to 1-inch in diameter. Use a fiberglass pole on a tripod and you are on the air! Check out our MFJ-1919EX a perfect mount for the new Octopus Antenna.
Perfect fro casual portable operation, limited space, HOAs, field day, camping, and ARES during disasters.
Single coas feed, built-in balun.

Interaction between bands is minimized because the ends are spaced apart at a large angle.

You don`t need an antenna tuner if you carefully tune each dipole. An easier way is to just set each dipole approximately on frequency and use an antenna tuner to operate and widen the bandwidth.

Hamsticks break down to four feet for easy storage.

Tough Octopus Hub
Eight 3/8-24 threaded connectors for hamsticks. Super stong fiberglass filled ABS base insulator. Your Octopus Hub will give you years of trouble-free service!
Based on Geoff Haines, N1GY, award-winning December 2007 QST article.

Super Octopus Deals
MFJ-2104, $249.95. Octopus hub with your choice of four (2 each) 250W Hamsticks. Saves $20!

MFJ-2104, $479.95. Octopus hub with your choice of four (2 each) 600W Hamsticks. Saves $20!

MFJ-16XXT Hamsticks handle 250 Watts PEP. About 7 feet fully extended, 4 feet collapsed.

MFJ-26XXT Hi-Q HamSticks handle 600 Watts PEP. Much larger diameter loading coil and wire gauge gives you higher-Q. Lower losses let you dramatically talk further and hear better. 101 inches fully extended, 53 inches collapsed.  (adsbygoogle = window.adsbygoogle || []).push({}); Antenna Universal DIY Carbon VHF Yagi Antenna February 15, 2017 No comments

Goodbye Bright Flares, Hello Dark Hole: Solar Storm Forecast 01-31-2019

QRZ Now - Fri, 02/01/2019 - 5:33am

This week the Sun comes out of hibernation with a fast growing active region and a large coronal hole rotating into Earth view. Although the region (2733) never launched any Earth-directed solar storms, it nevertheless fired off a few C-class flares that no doubt made the HF radio bands a bit noisy.

The flares may have also made GPS a bit glitchy around the dawn-dusk terminators. However, this bright active region has also boosted the solar flux back into the marginal range for radio propagation. As we say goodbye to region 2733 as it rotates to the Sun’s backside, we say hello to the large coronal hole that is starting to rotate into the Earth-strike zone. Aurora photographers, especially at high latitudes should get a great show over the next few days, possibly in through the weekend.

Photographers at mid-latitudes, may not be quite as lucky, but there might be a chance for some sporadic aurora starting late Thursday and into Friday. Learn the details of the activity this week, catch up on aurora photos from recent solar storming, and see what else our Sun has in store.
