The other day I was messing around and I noticed that the MFJ SWR
bridge on radio 2 was deflecting when I keyed radio 1.  I have a
home-brew all band vertical on radio 2 about 30 feet away from my
tower with the 20 and 15 meter ants on them.  Must be getting
some RF back into the radio 2 SWR bridge.  Probably not good!  73
