Good Morning Domenico:
In step 7 you wrote:
7)Without moving the audio and RF setting of the receiver start to play
tuning and adjusting everything is possible in your preamplifier i.e.
capacitors and inductances of the input network as well potentiometers
to set the active device current until switching the noise source ON and
OFF the maximum variation on the AC voltmeter is reached and this
condition correspond to the lovest possible Noise Figure obtainable
Looking for MAXIMUM variation in noise...is this correct or should it be looking for MINIMUM variation??
Than ks..I'll give it a try.
