You could adjust the tuner without causing QRM.  You could also adjust the 
tuneer for a good match on frequencies outside the ham bands, although there 
is probably not much advantage in doing this.

Subject: MFJ Noise Bridge General Quiry

Hi, all.

Please forgive this quiry, since I'm certain that, for many on the list, it
is rather elementary.

The recent discussion of the MFJ noise bridge, and its possible
discontinuation, is making me want to learn more about the product and its
potential usefulness for me.

Right now, when I am working with antennas and my Tentech 238A manual tuner,
I use the LDG TW1 to measure SWR, and both forward and reflected power.
Although I do find the TW1 to be less-than-totally accurate, especially on
the lower bands in comparison to the SWR/watt meter on my TS590, it has been
sufficient in meeting  my needs at least for the most part.

Is there a compelling reason why I might want to consider purchasing the MFJ
noise bridge?  In other words, what could it help me with that the TW1 is
unable to do?

Of course, one could always make the argument that the MFJ noise bridge
could serve as a useful back-up, should my TW1 die, which may be a good
enough argument in and of itself.

Just thinking out loud here, I guess.
