40m Projects - Amplifiers

Click to enlarge6AR5 7MHz 1watter linear amplifier by JF1OZL
Many old men said to me that they want to make QSO by the valve-homemade-machine like the old days. I will show you in this page the easiest way to use a home-made-valve-final. Today's rig has the power control system.

Ayant construit un kit de K2 durant l'hiver 2004, la question de la puissance s'est rapidement posée, trafiquer en QRP c'est amusant et formateur en CW, cela devient vite lassant en SSB sur 40 m tant pour vos correspondants que pour vous-même.
