EME Conference 2014
19-05-2014
Soumis par: ON4AVJ
La date limite d’enregistrement des réservations pour la conférence EME 2014 est fixée au 30 mai 2014.

Cette conférence dédiée au trafic via la Lune dans tous les modes et sur toutes les fréquences se déroulera les lundi 25 et mardi 26 août 2014 au Pôle Phoenix de la Cité des Télécoms à Pleumeur-Bodou dans les Cotes d’Armor.

Elle est organisée par l’association ORPB en liaison avec le Lannion Tregor Communauté et la Cité des Télécoms.

L’accueil des participants est assuré à partir du samedi 23 août. Plusieurs possibilités d’hébergement sont proposées au Club Belambra de Tregastel.

Des exposés scientifiques et techniques seront présentés au cours de ces deux journées par d’éminents spécialistes dans différents domaines tels que les antennes, les systèmes de poursuite, les amplificateurs et préamplificateurs, les SDR, les systèmes de traitement du signal, la propagation, …

Monsieur Joseph Taylor K1JT, prix Nobel de physique et concepteur du WSJT, nous honore de sa présence. Sergey Zhutyaev RW3BP, Paul Wade W1GHZ, Al Katz K2UYH, et de nombreux autres contributeurs de renom sont déjà inscrits et exposeront eux-mêmes leur sujet.

Le lundi soir après le diner un forum est organisé entre radioamateurs, scientifiques, professionnels, responsables d’université et étudiants afin de définir des solutions de partenariat.

Au cours de ces deux journées des ateliers de mesures de facteur de bruit et de puissance jusqu’à 24GHz seront animés par des radioamateurs français connus qui ont accepté d’organiser ces ateliers avec leur propre matériel de labo.

Enfin deux stations seront actives sous les indicatifs TM8PB et TM16EME.

Des démonstrations de liaisons EME que ce soit en mode numérique ou analogique seront assurées par petits groupes soit avec la parabole PB8 de 13m soit avec un équipement portable.

Cette 16ème conférence est la seconde organisée en France (Paris 1998). Elle permet à des radioamateurs du monde entier, adeptes de ce type de trafic de se retrouver tous les deux ans dans un cadre extrêmement convivial et amical afin de mettre en commun leur savoir faire et leurs compétences.

Des activités touristiques sont également prévues pour les accompagnants/accompagnantes. Ainsi, de nombreuses délégations étrangères souvent lointaines en profitent pour visiter le pays organisateur.

Pour celles et ceux intéressés vous pouvez consulter le site EME 2014. Pour tout renseignement sur les inscriptions et l’hébergement contactez cette adresse email.
UK Amateurs Losing Access to Part of 2.3 GHz and 3.4 GHz Bands
15-04-2014
Soumis par: ON4AVJ
UK telecommunications regulator Ofcom has announced that it’s ending Amateur Radio access to significant portions of the 2.3 and 3.4 GHz bands.
The action, announced on April 7, came in the wake of a year-long “consultation” — a rule making proceeding — that involved the release by the Ministry of Defence of 40 MHz of spectrum at 2.3 GHz and 150 MHz of spectrum at 3.4 GHz. Amateur Radio is secondary on the bands.

Amateur Radio will lose privileges on frequencies in the two bands that overlap with spectrum that Ofcom plans to award for “new civil uses” — 2350 to 2390 MHz and 3410 to 3475 MHz. The announcement gives radio amateurs at least 12 months’ notice, but radio amateurs must comply immediately with procedures to avoid interfering with other users; ham radio occupants of 2310 to 2350 MHz will have to register their use and provide details to Ofcom.

Amateur Radio will retain access to the adjacent bands, but Ofcom has put procedures in place to remove even those frequencies from Amateur Radio access, if necessary in the future. Ofcom said earlier this year that with military and other government use of the 2.3 and 3.4 GHz spectrum ending, “we believe an award of the spectrum for high power use is likely to deliver greater benefit to UK consumers and citizens than continued amateur use.” Ofcom was required by the Ministry of Defence to adequately protect its systems from Amateur Radio interference in both the released spectrum and in adjacent bands.

“The MoD’s plans are part of a government commitment to release 500 MHz of spectrum by 2020,” Ofcom explained in its order. “This commitment to opening up spectrum for new civil uses is based on growing demand from UK consumers for spectrum-hungry devices such as smartphones and tablets.” Ofcom said that use of mobile data devices more than doubled in the 18 months leading up to January 2012. “Indeed, the 2.3 and 3.4 GHz bands are identified in Ofcom’s ‘mobile data strategy’ as having the potential to support even better mobile data services for citizens and consumers in the coming years,” the regulator said.

Ofcom said it was making 2300 to 2302 MHz available for amateur use, but licensees first must obtain a Notice of Variation to their licenses. Hams in the US have secondary access to 2300 to 2310 MHz, 2390 to 2450 MHz, and 3300 to 3500 MHz. — Thanks to RSGB, Ofcom
ARISS: Ham Video Commissioning – final
15-04-2014
Soumis par: ON4AVJ
The final Ham Video Commissioning Pass 4 is planned Sunday April 13 at 18.23 UTC.

Configuration 4 will be used:
  • ARISS antenna 43
  • Frequency 2395 MHz
  • Symbol rate 2.0 MS/s
Koichi Wakata will operate OR4ISS.
Ground stations F6DZP and IK1SLD will receive the signals and stream the video over the BATC server.
The video is expected to be received during 5 minutes.

This will mark the end of the Blank Transmissions.

We thank the operators who filed reception reports of blank transmissions. Your participation to the Ham Video testing campaign has been invaluable.

No decision has been taken yet on the future use of Ham Video. We will keep you informed on any progress.

ARISS: video blank transmissions
11-04-2014
Soumis par: ON4AVJ
Presently, Ham Video is transmitting permanently a “blank” image and no audio in configuration 5:
  • ARISS antenna 43
  • Frequency 2369 MHz
  • Symbol rate 1.3 Ms/s
Reports on reception of blank transmissions are very welcome. Reports can be filed via this webpage: http://www.spaceflightsoftware.com/ARISS_FSTV/submit.php.

Participants using the Tutioune receiving software can record as well as stream detailed parameters of the received signal. Please see: http://www.vivadatv.org/.

Reports are available at http://www.vivadatv.org/viewtopic.php?f=66&t=294&p=785#p785.

Thank you for your participation to the Ham Video testing campaign.

Afin de créer de l'activités en D-Star et faire de nouveaux adeptes, la section UBA de Thuin indicatif ON6TN à décidé de mettre un QSO D-Star en fonction à partir du samedi 6 avril 2013.

En voici les modalités: chaque samedi après midi à partir de 15 h 00 heure local se déroulera le QSO européen en D-Star. Nous serons probablement sur le réflecteur 028 au début. Notre objectif est de faire découvrir le D-Star et également de faire trafiquer les OMs de la section. Évidemment nous invitons tous les OMs à participer à ce nouveau QSO européen en D-Star

A new Next Generation Beacon
02-04-2013
Soumis par: ON4AVJ
Today, Saturday 30 March, is the 56th anniversary of OZ7IGY and also the launch date for the new 70 cm beacon based upon the Next Generation Beacon platform: http://www.rudius.net/oz2m/ngnb.

The 70 cm beacon is now frequency and time locked to GPS. The sequence is timed to start at 00 second sending PI4 followed by a short pause then CW ID sending callsign and locator, then pause and carrier until next cycle. The nominal frequency remains the same, i.e. 432,471 MHz. To decode PI4 tune your receiver to 800 Hz below the nominal frequency, just like you do when you want to decode a normal CW signal at 800 Hz. On most radios this is a USB dial of 432.470.2.

At the same time the 6 m, 4 m and 2 m beacons have also changed MGM to PI4. The CW callsign, locator and carrier remain the same.

PI4 is a digital modulation (MGM) specifically designed with beacons and propagation studies in mind.

Download PI-RX to decode PI4: http://www.rudius.net/oz2m/ngnb/pi-rx.

PI4 encoding examples in Arduino C, Atmel C, Delphi Pascal, Microsoft Visual Basic and Microsoft C++: http://www.rudius.net/oz2m/ngnb/software.htm.

PI4 online encoding and frequency calculation: http://www.rudius.net/oz2m/ngnb/pi4encoding.php.

PI4 specification: http://www.rudius.net/oz2m/ngnb/pi4.htm PI4 is a cousin of JT4, JT9 and WSPR.
