YAESU FT-950

C’est avec empressement que je vous signale le dernier produit de la gamme Yaesu, j’ai nommé le FT-950.

ft-950yaesu.jpg

Présenté à la « Tokyo Ham Fair 2007« , le dernier-né de la gamme est annoncé comme un (autre) successeur du FTDX9000. Il couvre HF & 50MHz, avec une puissance de 100W (25W AM) et DSP en émission/réception (Variable Bandwidth, IF Shift, & Passband Contour tuning, Digital Noise Reduction, Digital Auto-Notch Filtering Notch IF manuel). Il disposera en série d’une boîte d’accord automatique.

Plusieurs des options actuellement existantes pour le FT2000 lui seront applicables, notamment le DMU2000 et les pré-sélecteurs « µ-tuning ».

En émission, un équaliseur à trois bandes ravira les adeptes de l’E-SSB.

Pour le reste, fonctions habituelles. En résumé, c’est donc un FT2000 sans deuxième récepteur. Comptez 1500 Euros..
