Portrait : Valdemar Poulsen by J.-C. Montagné.
We don't wish to take off the freshness of the paper of our friend A. Remond, about magnetic recording, but it is advisable to devote words about the danish engineer Valdemar Poulsen.

History of techniques :
De Poulsen au disque dur. Chapitres 1 et 2 by A. Rémond.
La découverte de l'électromagnétisme - Vers un système d'enregistrement...
Nowadays, inserting a cassette in a tape recorder to enjoy music or movies is trivial. However, it is worth to recall, now and again, that the involved technologies did not appear at the first attempt. Eight chapters will tackle the developement of magnetic recording from Poulsen's Telegraphone to computer.

The HAM page :
Qui a voulu tuer le Morse ? by R. Houzé.
Pr Houzé gives hereafter a comparaison between the complicated telematique and the simple Morse code.
Le merveilleux HRO by E. Bourgougnon.
Petite histoire d'un mythe mondial
When radio amateurs talk about HRO, they have always a pleasant remembrance, specially in France, where the pre-war price of the receivr was dissuasive. Post-war prices of military surplus was a real bargain for them.

Atelier :
Le coin de la superréaction by C. Maennel.
An example of a superregenerative receiver using a separate oscillator. This oscillator changes the anode voltage of the superregenerative stage, alternatively starting and stopping high frequency oscillations. This results in a high gain.
