Hi Tom,
The noise bridge that I and Jim, w8qlr, use is from Vectronics (MFJ) and is
the model VEC512. What We like is that the noise that you null is pulsed
and is very easy to distinguish from other noise.

No, I do not know where you can buy a noise bridge, but I bet others on this
list will know.
We'll see. ... Depending on how things go here, I may be in the market for
one myself. In the mean-time, I'm going to try working with the Remy Simard
talking SWR meter, and see how far that gets me.
