Topband: Palomar R-X Noise Bridge

[Carl]

I used a noise bridge to cut all the RG-11 stacked yagi and phased verticals 
phasing lines as well as harmonic stubs here when running a 2 station single 
op contest, before SO2R.

Using the station receiver also works well as the backround noise null is 
easily heard. I did that several times when a 9V battery was dead and 
compared results later, they were right on.
