by Raymond AUPETIT 31 Jan '14

31 Jan '14

Bonjour Une info de F6CPI et F5RUJ. Bonne lecture et 73 de Raymond.F-15873. A diffuser largement SVP. Tout le monde pourra acquérir l'objet, membre UFT ou non. Pour le moment c'est juste un sondage pour tester la faisabilité du projet. Le manip serait une pioche réplique d'un modèle ancien en laiton mais pas aussi sophistiqué que celui représenté sur cette image! ____________________________________________________________________________________________________________________________ Communiqué de l'Union Française des Télégraphistes Le modèle de pioche Marconi utilisé sur le Titanic Il ne représente pas celui du trentenaire En mai 2015, l'UFT aura 30 ans ! A cette occasion, nous avons le projet de vous proposer d'acquérir une belle "pioche" commémorative de cet évènement . Nous ouvrirons une souscription prochainement, dès que le modèle sera défini . Auparavant , afin de connaître le nombre d'YL et d'OM intéressés à priori par cet achat de manipulateur "collector", envoyez dès maintenant un email à Christian F9WT f9wt(a)ref-union.org . Le prix de cette pioche devrait être proche d'une centaine d'euros.

Fw: [examen_f0_f4] Examen n° 17387 du 24/01/14 à Nancy
by Raymond AUPETIT 28 Jan '14

28 Jan '14

Bonjour Comme promis, de temps en temps je vous transfère un msg de la liste F0-F4 suite à passage d'examen. En voicii une récente qui peut lancer de nombreuses discussions ! 73 de Raymond. F-15873 Bonsoir à tous, Ci-joint le compte rendu de Baptiste qui a réussi l'examen le 24/01/14 à Nancy. Mes commentaires sont en rouge. Dans ce compte-rendu, nous revenons sur l'utilisation de la calculette à l'épreuve de réglementation : il semble que les centres de Nancy et de Villejuif autorise la calculette alors que le centre de Toulouse ne l'autorise pas. Un point qui mériterait à être éclairci lors d'une prochaine réunion de travail ANFR/association. 73 de F6GPX Jean Luc Bonjour, J'ai passé cet après-midi (24/01/14) mon examen radioamateur avec succès, à Nancy, à l'issue d'une préparation rapide d'un mois. Votre logiciel m'a fort aidé dans cette préparation et je vous en remercie mille fois ! Pas de remarques sur les questions posées, elles étaient toutes dans la base. Un petit détail cependant, j'ai lu sur divers forums qu'il y avait un doute sur l'autorisation de la calculatrice pour l'épreuve de réglementation. Pour ma part, j'avais envoyé un mail à l'organisatrice avant l'examen qui m'a répondu ceci : la calculatrice est autorisée pour la totalité de l'examen (réglementation et technique) ; celle-ci ne doit pas être programmée avec les formules Précisions sur l'examen du 6/1/14 (message précédent, n° 491). Suite au compte-rendu de Baptiste, j'ai demandé à Antoine qui m'avait fait son compte rendu il y a quelques jours des compléments d'information sur ses conditions d'examen et, en particulier sur l'utilisation de la calculette à l'épreuve de réglementation. Sa réponse est sans appel : "De mon côté, c'était totalement cool : aucun contrôle du modèle de la calculatrice, calculatrice possible pour les 2 épreuves. Aucune info particulière avec la convocation. Ce qui est sûr, c'est que la surveillante (à mon avis, une agente administrative sans compétence technique) avait un manuel d'instructions sur son bureau. Mais était-ce un manuel pour le logiciel d'examen ou pour tout l'examen ? Je ne sais pas dire, ne l'ayant pas vu de près. Bon courage pour forcer à l'ANFR à s'harmoniser ! " Effectivement, il va falloir que l'ANFR nous explique pourquoi les règles sont différentes selon les centres d'examen. Soit le centre de Toulouse fait du zèle, soit les autres centres (Nancy et Villejuif) ne suivent pas les consignes du siège... Pas de remarques sur les questions posées, elles étaient toutes dans la base. Ci-joint mon compte-rendu (scan joint), avec les questions dont je me souviens. Je ne me rappelle plus de toutes les réponses toutefois. Réglementation : - Schéma avec un un câble et une antenne avec indication : Puissance d'émission (Pém) = 10 W et puissance réfléchie (Préf) = 4 W. Quel est le TOS ? Taux de puissance réfléchie = 4/10 = 0,4 (ou 40%), TOS = racine (taux de puissance réfléchie) = racine (0,4) = 0,6324 = 63% (arrondi). Pour avoir un calcul plus simple, réalisable sans calculette, il aurait fallu avoir des valeurs en volts (et non pas en watts) ; dans ce cas, la réponse aurait été 40% (=4/10). - Schéma avec un un câble et une antenne avec indication : Ze = 190 ohms et, sous l'antenne, Za = 300 ohms. Quel est le ROS ? Réponse : ROS = Z plus forte / Z plus faible = 300 / 190 = 1,58 / 1 (arrondi). Ces deux questions sont impossibles à résoudre sans calculette. Les candidats passant leur épreuve à Toulouse vont être gênés. Ou alors, la base de données des questions n'est pas la même... - Comment s'épelle F8DAX ? Foxtrot 8 Delta Alpha X-ray - Comment s'épelle F4WTP ? Foxtrot 4 Whiskey Tango Papa - Préfixe de l'Albanie ? ZA - Puissance dissipée maximum en dessous de 28 MHz ? 500 W - Statut de la bande des 50 MHz (réponses proposées : fixe et mobile, mobile uniquement, ...) réponse : tous les types de station sont autorisés : fixe, portable, mobile (et même maritime mobile). La bande des 50 MHz est, depuis la décision 12-1241 est une bande "normale", sans restriction. - Pour émettre, il faut : (réponses proposées : être membre d'un radio-club, avoir un indicatif (bonne réponse), s'être inscrit à l'examen, avoir réussi l'examen) - 2 produits d'intermodulation d'ordre 3. Les produits d'intermodulation d'ordre 3 sont les mélanges des 2 fréquences (F1 et F2) présentes à l'entrée d'un amplificateur non linéaire. A la sortie de cet amplificateur défectueux, on trouve des mélanges de 3 fréquences comme par exemple : 2 x F1 + F2 ou F1 - 2 x F2 ou encore 3 x F1. Nouvelle question, jamais posée (y compris dans la partie technique du programme) ; les questions portant sur les produits d'intermodulation étaient, jusqu'à présents plus générales et sans calcul. Technique : - 2 résistances à décoder, une a "la tête en bas" La présentation d'une résistance " la tête en bas" (code couleur à lire de bas en haut) est assez rare. A ce jour, un seul compte rendu avait mentionné cette présentation) - Entrée : 40 W, Sortie : 10 W ; quel est le gain (en dB) ? rapport de puissance = Ps / Pe = 10 / 40 = 1/4 correspondant à -6 dB. Attention au piège avec une puissance de sortie plus faible que la puissance d'entrée (atténuation) - Veff = 10 V ; calculer Vmax réponse : Vmax = Veff x 1,414 = 14,1 V - circuit RLC, calculer Q. formule : Q = racine (L/C) / R - période d'un signal avec lambda = 2,5 cm ? calcul de la fréquence : F(MHz) = 300/ (L(m) = 300 / 0,025 = 12000 MHz ou 12 x 10^9 Hz, durée de la période : t(s) = 1 / F(Hz) = 8,33 x 10^-11 = 83,3 x 10^-12 = 83 ps (picosecondes). Nouvelle question, jamais recensée dans les comptes rendus précédents. - schéma avec un transistor , une résistance de 1,5 kohms sur la base et 1 kohm sur le collecteur. Indication : Ic = 1,5 mA et beta = 150. Déterminer Ibase réponse : Ic = Ibase x beta, donc : Ibase = Ic / beta = 1,5 mA / 150 = 0,01 mA = 10 µA - une bobine de 4 mH a 5 spires. Quel doit être le nombre de spires pour que la même bobine fasse 16 mH ? (réponses proposées : 10 (bonne réponse), 15, 25 et 20). La formule générale est : L(H) = F x n² x D². En conséquence, en doublant le nombre de spires, on quadruple la valeur de la bobine Au plaisir de vous croiser sur les ondes, Merci encore !
