EA5GTU/P DESDE SU BALCON EN LA MANGA, Murcia, ESPAÑA con YV5MM MODO ROS

ROS with balcony antenna

By José Alberto Nieto Ros This antenna is used by EA5GTU/P during his holidays  in La Manga (Spain). Besides of  this antenna being low efficient on HF, he could contact with YV5MM (Venezuela) with ROS.


And this is an example of how you should not configure your Rig filter. In this case ROS frequencies below 1000Hz are lost in a Icom-7000. However the contact with YV5MM could be completed in the worst conditions.

NOAA - TEMPORADA DE HURACANES EN EL ATLANTICO - IMPORTANTE INFORMACION

NOAA's Atlantic hurricane season update calls for increase in named storms

Forecasters have higher confidence for an active season

NOAA issued its updated 2011 Atlantic hurricane season outlook today raising the number of expected named storms from its pre-season outlook issued in May. Forecasters also increased their confidence that 2011 will be an active Atlantic hurricane season. NOAA’s Climate Prediction Center, a division of the National Weather Service, updates its Atlantic hurricane season outlook every August.
“The atmosphere and Atlantic Ocean are primed for high hurricane activity during August through October,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at the Climate Prediction Center.  “Storms through October will form more frequently and become more intense than we’ve seen so far this season.”
Key climate factors predicted in May continue to support an active season. These include: the tropical multi-decadal signal, which since 1995 has brought favorable ocean and atmospheric conditions, leading to more active seasons; exceptionally warm Atlantic Ocean temperatures (the third warmest on record); and the possible redevelopment of La Niña.  Reduced vertical wind shear and lower air pressure across the tropical Atlantic also favor an active season.
Based on these conditions and on climate model forecasts, the confidence for an above-normal season has increased from 65 percent in May to 85 percent. Also, the expected number of named storms has increased from 12-18 in May to 14-19, and the expected number of hurricanes has increased from 6-10 in May to 7-10.
Across the entire Atlantic Basin for the whole season – June 1 to November 30 – NOAA’s updated seasonal outlook projects, with a 70 percent probability, a total of:
  • 14 to 19 named storms (top winds of 39 mph or higher), including:
  • 7 to 10 hurricanes (top winds of 74 mph or higher), of which:
  • 3 to 5 could be major hurricanes (Category 3, 4 or 5; winds of at least 111 mph)
These ranges are indicative of an active season, and extend well above the long-term seasonal averages of 11 named storms, six hurricanes and two major hurricanes.
The Atlantic basin has already produced five tropical storms this season: Arlene, Bret, Cindy, Don and Emily. All eyes this week are on Emily, which continues to develop and move towards the United States.
The last hurricane to make landfall in the United States was Ike in 2008. Last year saw above-normal hurricane activity, but none made landfall in the United States. August through October are peak months of the Atlantic hurricane season, and FEMA urges people not to be lured into a false sense of security by the lack of hurricanes so far this year.
"It is still early in this hurricane season and we know it can take only one storm to devastate communities and families," said FEMA Deputy Administrator Rich Serino. "Many disasters come without warning, but that’s not the case with hurricanes. This is hurricane season, if you haven't already, now is the time to take a few simple steps to get you and your family prepared. Anyone can visit www.ready.gov to learn more."
Be prepared for the hurricane season with important information available online at hurricanes.gov/prepare and at FEMA’s ready.gov.
NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join us on Facebook, Twitter and our other social media channels.

Russian Spacewalkers to Move Cargo Boom, Deploy Ham Radio Satellite
07.29.11

Two Russian cosmonauts will leave the confines of the International Space Station on Aug.3 to move a cargo boom from one airlock to another, install a prototype laser communications system and deploy an amateur radio micro-satellite.

Expedition 28 Flight Engineers Sergei Volkov and Alexander Samokutyaev are scheduled to venture outside the Pirs airlock at 10:30 a.m. EDT Wednesday to begin the six-hour excursion. Both spacewalkers will wear Russian Orlan-MK spacesuits. Coverage of the spacewalk will be broadcast live on NASA Television beginning at 10 a.m. EDT.

Volkov, making his third spacewalk, and Samokutyaev, making his first, will both wear spacesuits marked with blue stripes. Volkov’s previous two spacewalks occurred while he was Expedition 17 commander in 2008.

During the spacewalk, Commander Andrey Borisenko and NASA Flight Engineer Ron Garan will close the hatches on the Poisk docking module, which is opposite the Pirs airlock, and seal the hatches between Zvezda and Poisk. This gives them access to their Soyuz 26 spacecraft, protects against the unlikely possibility of a sudden station depressurization and allows the forward transfer compartment of Zvezda to be used as a backup airlock. Flight Engineers Mike Fossum of NASA, and Satoshi Furukawa of the Japan Aerospace Exploration Agency, will be in the U.S. segment and will have access to their Soyuz 27 spacecraft, which is docked to the Rassvet module.

The duo’s first task will be to deploy a boxy, 57-pound satellite, called alternately ARISSat-1 and Radioskaf-V, which is the prototype test flight of a proposed series of educational satellites being developed in a partnership with the Radio Amateur Satellite Corp. (AMSAT), the NASA Office of Education ISS National Lab Project, the Amateur Radio on ISS (ARISS) working group and RSC-Energia.

The ARISSat design can carry up to four student experiments and the data from these experiments will be transmitted to the ground via an amateur radio link. This prototype ARISSat-1 carries one student experiment, a pressure sensor built at Kursk University in Russia, to measure atmospheric pressure for the lifetime of the satellite.

In addition to transmitting student experiment data, ARISSat-1 will transmit still-frame video Earth views from four onboard cameras, commemorative greetings in the native languages from students around the world, including messages to commemorate the 50th anniversary of the launch of Russian cosmonaut Yuri Gagarin as the first human in space. The satellite, which uses off-the-shelf equipment and software provided by AMSAT, also features a Morse code tracking beacon and will function as a space communications utility for use by “ham” radio operators world-wide.

More information on tracking ARISSat-1 decoding its telemetry visit the AMSAT and ARISSat-1 websites:

http://www.arissat1.org/v3/

http://www.amsat.org/amsat-new/

Their next job will be to install a barbecue grill-shaped experiment to test the use of a laser-based system for high-speed transmissions at up to 100 megabytes a second to the Earth from Russian science experiments. The system will be installed on a universal work platform outside the Zvezda service module hull just behind its solar arrays.

After that, they’ll take photographs of a nearby antenna that has been showing signs of degraded performance. The imagery will be used to help engineers on the ground find the root cause of the antenna’s problem.

Next, they’ll retrieve an antenna that was used for docking of the Poisk module when it arrived at the station in November 2009. The antenna is no longer needed and will be brought back inside the station.

Then it is on to the major objective of the spacewalk, the move of the telescoping STRELA-1 cargo boom from the Pirs docking compartment to the Poisk docking compartment. The task is expected to take nearly three hours to complete, and will involve the use of the STRELA-2 boom, with its base attached to Pirs. At the completion of the task, STRELA-1 will be ready for use from Poisk, and STRELA-2 will remain on Pirs. The cargo booms extend somewhat like a fishing rod, and can be used to help move massive components around the outside of the Russian segment of the space station.

Once the boom relocation is complete, the spacewalkers will retrieve an experiment known as Biorisk from the airlock, and install it on a handrail outside the Pirs module. Biorisk is short for the Influence of Factors of the Space Environment on the Condition of the System of Microorganisms-Hosts Relating to the Problem of Environmental Safety of Flight Techniques and Planetary Quarantine. The experiment will look at the effects of bacteria and fungus on structural materials used in spacecraft construction with a focus on how solar activity may affect the growth of these microbes.

With all tasks complete, Volkov and Samokutyaev will take some final photographs, reenter the Pirs airlock and end their spacewalk.

The next Russian spacewalk is planned for February 2012, when the Expedition 30 crew will be in orbit aboard the station.
