[TenTec] Radio for soon to be newbie General....

[Al Gavenas]

It seems like most hams want to run their rigs with the RF gain
wide open and ride the volume control to adjust the audio output
to a comfortable level.  What you should do, is run the audio volume 
control wide open and ride the RF gain control to adjust
the audio output to the comfort level.

There was something in QST a while back about this and it makes a lot of 
sense.  What comes in the front end of your rig is the sig you
want  along with unwanted  noise.  Hopefully, the sig rides above the 
noise.   The trick is to amplify the sig and not the noise at the
front end of the rig.  By adjusting the RF gain what you want to do
is push the noise down to below the threshold that the front end
of the rig can grab and amplify.  But you do want to amplify
the sig.  The noise blanker helps on some types of noise but I think you 
can knock out more noise with proper use of the RF
gain control than you can with a noise blanker.  The purpose
of the filters in the rig has to do with selectivity and not noise.
Selectivity has to do with selecting the one sig among the many
out there that you want to hear.  Have I made myself clear????

I think a lot of hams need to be educated about this.
