Butch,
Great Explanation! The only thing that I'd like to add is that even though
the Vectronics VEC512 has a bypass circuit in it, always remember to turn it
off before transmitting. I've messed up a few times and no damage, but the
relay in the noise bridge is very small and won't take much abuse, but its
better than a fuse you'll have to replace every time you transmit by
accident.
