It does not mean this feature is used often. I sometimes (very seldom) need antenna tuner but almost never use the second antenna port. So there were no point for me to pay for this feature. Having said that, I often use SubRx connector for the sub RX. > > Just let me explain and share with everybody how I switch the K3 audio and > why I donot want to do this 'outboard'. > During the last CQ 160 CW at PI4D I had the main transmitting antenna > connected to the K3 Ant1 and a receive antenna to the RX ant connector. > I linked A and B VFO together with same mode, freq and fixed BW (400Hz) > and listened A-B, like diversity. Same here. Nothern and Western antennas combined and connected to the main RX.

When there is need to pull out weak signal from one of the directions I can put one radio into both ears. The switch is near the keyboard so no problems to do switching. But external switching allows also the use of the 3rd radio ( mult hunting on a different band) where one can mix the third radio into one of the 2 channels. This mix can be regulated (balanced) with the resistor pot installed in the same external box. Should I need more options it can all be easily implemented externally. 73, Igor UA9CDC > > By the way: The Ab-Ba setup is implemented in a FT1000MP as a standard > listening method when you listen to main and sub RXs.
