Jim,

The noise bridge allows you to tune your tuner for the lowest swr with out 
transmitting on the air.  I first peak my external tuner for max signal and 
then turn on the noise bridge to null out the noise for the best swr. 
Sometimes the settings between max received signal are the same as the 
lowest swr point, but most of the time, the settings are slightly different.

What is the benefit of owning a noise bridge? I have been a ham
since 1973 and have never owned one.  Jim WA6EKS

Hi Dave,

I don't know if the MFJ noice bridge has a bypass relay, but MFJ
tech
support
should know.  Can you let me know what you find out?

HI Bob,

Do you by any chance know whether the MFJ noise bridge has the
bypass
for RF that the Vectronics noise bridge has?  I can order the MFJ
from Ham Radio outlet in Portland.  I'm shy of getting it if
doesn't
have the bypass circuit as I burned the pot in a friend's Palomar
noise bridge a couple of decades back.  The MFJ manual I
downloaded
from the internet doesn't seem to say anything about it.  Maybe I
will phone HRO today and see if they know.

73,
