Hi
     My noise bridge is an old fuse protected type. I have a hard time 
getting the little fuses, but it does a great job for me. It is especially 
helpful in those areas of the band that are out side the ham band.

God bless,
Mark
God loves You!

I have a new one from MFJ that is really a reseller for another
company.  It is RF protected up to 300 watts I believe.  A relay is
used to take the unit out of the circuit.  I used it to tune my
external tuner for minimum SWR.  I had to turn the RF gain way down
to hear the change in noise.  The noise pulses, but it is hard to
hear the change with the RF gain up and AGC turned on.  I haven't
used it much, but it worked fine for me.
