In fact, impedance transformer was by-passed also.
Now it is fixed. I have driver stage to the variometer through the 
transformer. Neon lamp lights up more !

Please check next transmission

Thank you.

Dom.

        The power reduction that i'm now using is the built-in circuit
        of the PA (ex-marine reserve transmitter): one relais takes the
        output of the driver stage and <br>
        brings it directly to variometer. <br>
        <br>
        To match my antenna it is necessary one transformer before the
        variometer.  I'm now checking if there is some impedance
        mis-matching when final stage is by-passed.<br>
        So, work in progress.<br>
