Tom,

A noise bridge will null as you approach a 1:1 Swr.  It doesn't require you 
to transmit a signal at all.

The Atom is just a device which reads Max output from the Xmitter.  It 
requires you to transmit and you basically tune for maximum output, or 
smoke.

The old Conway tuning aid was a voltage-controlled oscillator you could hook 
across any meter to read its output.

   Butch or anyone:

I know this will be elementary for some, but can someone give me a little
tutorial on the difference between a tuning aid like Adam, and a noise
bridge?

I have never used a noise bridge, like the Victronics or MFJ, and wonder how
they work in comparison to a tuning aid like the Adam or the one Handihams
used to sell.

Just a little lacking in knowledge here.
