Hi Yes, for me it has a very real advantage. Most of the time the K3 is in 'diversity mode' although I am not strictly listening in diversity as my antennae are pointing in different directions. The advantage for me is that the receivers are locked together as well as they can be - including the filtering.
I'll make up a switch box / balance control. I didn't expect this thread to grow quite the way it has! Thanks for the info. 73 Ian.
