[Johnson] A question from A New BA operator.

Tuning for reduced power in the VIKING II:

In the instruction manual of the Viking II, we find the following, on page 9:

NOVICE OPERATION
"Current FCC regulations require that operators with Novice Class Amateur 
Operator's Licenses limit theit final amplifier input to 75 watts.  This 
may be accomplished with good efficiency by reducing output coupling.

In the "plt" position of the meter switch, the meter indicates 6146 cathode 
current, the sum of plate and screen grid currents.  With 6146 grid current 
at 6 ma. and the amplifier resonant and drawing 140 ma.  cathode 
current,  the screen current will be 30 ma.  and the net plate current will 
be 110 ma.  This is slightly less than 75 watts input with 660 volts plate 
voltage.  Amplifier output can exceed 55 watts under these conditions."

I guess that a similar procedure can be applied to the Valiant?

73's to all.
