 Hello

this is my 144 MHz GS35b Amplifier.

It´s a modified DJ5RE Design.

On top you see the blower, left is the HV- Capacitor, down under is the flapper, in the middle is the GS 35B and right is the lambda/4 output.

 The Blower is by a Central Oil heater.

 The plumber said: it runs for month without any Problems

 Or are you freezing, during the winter time?

 All right! Thats what i need and the best of this blower is...

 It´s free, but used. Ask your local plumber...

 Good luck!

This is the Aluminium frame.

More Details you will find in DUBUS Article by  DJ5RE.

In Test construktion .Maybe there is a finished photo later



The original DJ5RE design is resonant on 130 MHz. To tune to 140-150MHz you have to cut the stripline

2,5 cm .
