ISS AMATEUR RADIO CUBESAT DEPLOYMENT POSTPONED
ISS Amateur Radio CubeSat deployment postponed
JAXA have announced that the deployment of five CubeSats from the International Space Station (ISS) planned for September 10 has been postponed due to an additional EVA taking place September 5. A new deployment date has not yet been announced.Four of the CubeSats carry Amateur Radio payloads, they are F-1, FITSAT-1, WE-WISH and TechEdSat.
The small satellites, just 10cm cubed, were transported to the ISS in the HTV-3 cargo vessel that blasted off on an H-IIB rocket from the Tanegashima Space Center on Saturday, July 21 at 02:06 UT.
They arrived at the ISS on July 27 and were unloaded by the Expedition 32 crew.
The CubeSats are mounted in a JEM-Small Satellite Orbital Deployer (J-SSOD). In one pod are FITSAT-1, TechEdSat and F-1 and in the second pod is WeWish and a scientific 2U CubeSat RAIKO. Japanese astronaut Akihiko Hoshide KE5DNI will use the ISS Kibo robot arm to deploy the pods as demonstrated in this video.
Watch the planned deployment of the CubeSats from the ISS
The CubeSat frequencies are:

FITSAT-1
Este texto, sobre el conocido y esperado CUBESAT, lo recibí de Alberto - LU1DZ:



Un proyecto originario de Japon incluye la puesta en
orbita de un pequeño satelite destinado al estudio de las comunicaciones opticas
entre estaciones de navegacion espacial.
Se trata de un CUBESAT denominado FITSAT-1 (NIWAKA) http://www.fit.ac.jp/~tanaka/fitsat.shtml que utilizando la tecnica de LEDs emitira señales luminosas pulsantes de 200W en Codigo Morse las que se podrian visualizar durante el periodo nocturno.

El Profesor Takushi Tanaka http://www.fit.ac.jp/~tanaka/ director
del proyecto, remarca que sera posible observar las señales de Morse a simple
vista sin necesidad de ninguna ayuda y que una vez en orbita el NIWAKA navegara
entre los 51 6 ° de latitud Sur y los 51 6° de latitud Norte.
El FITSAT-1 y la estacion terrena utilizando telescopios
especiales llevaran a cabo experimentos de comunicacion en Morse de alta
velocidad entre ambos puntos con 3 minutos de duracion.
Asi mismo se efectuara una experiencia de comunicaciones
en 5,8 GHz y llevara un beacon de 430 MHz. de CW comenzando en Morse
internacional con HI y una serie de 18 parametros de medicion y tambien emitira
en Packet AX25 a 1200 Baudios.

JAMBOREE ON THE AIR - KF5AQG IS PLANNING TO BE ON THE AIR FROM THE INTERNATIONAL SPACE STATION AS NA1SS
If you are planning on participating in this weekend’s Jamboree On the Air (JOTA), take note: Astronaut Mike Fossum, KF5AQG, is planning to participate in JOTA from the International Space Station, using the call sign NA1SS. According to the AMSAT website, Fossum’s schedule is somewhat flexible on the weekends, but he will not be available for every pass. The typical crew work periods are 0800-1930 UTC, but they are sometimes available a bit later. When available, Fossum will be operating on the standard ISS frequencies. In the US and elsewhere in IARU Regions 2 and 3, the uplink is 144.49 MHz. In Region 1, the uplink is 145.200 MHz. The worldwide downlink for NA1SS is 145.800 MHz.

DX Code Of Conduct
DX Code Of Conduct
(various languages inside)
- I will listen, and listen, and then listen again before calling.
- I will only call if I can copy the DX station properly.
- I will not trust the DX cluster and will be sure of the DX station's call sign before calling.
- I will not interfere with the DX station nor anyone calling and will never tune up on the DX frequency or in the QSX slot.
- I will wait for the DX station to end a contact before I call.
- I will always send my full call sign.
- I will call and then listen for a reasonable interval. I will not call continuously.
- I will not transmit when the DX operator calls another call sign, not mine.
- I will not transmit when the DX operator queries a call sign not like mine.
- I will not transmit when the DX station requests geographic areas other than mine.
- When the DX operator calls me, I will not repeat my call sign unless I think he has copied it incorrectly.
- I will be thankful if and when I do make a contact.
- I will respect my fellow hams and conduct myself so as to earn their respect.

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
August 4, 2011

“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)
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.
