Description
Français : Poste a galène pour l'écoute de la bande hectométrique et de la bande kilométrique; l'amplificateur BF est en deux étages en cascade (écouteur actionnant un micro au charbon par une même membrane). L'ondemètre est utilisé pour le réglage du poste/antenne. Le ticker est remplacé par l'ondemètre faiblement couplé qui hétérodyne la porteuse (et donne un semblant de réaction). Ce poste a galène donne une image de la technique radioélectricité vers 1914. Utilisé pour: l'aviation et le maritime.
