David Can't agree more with what you say about the KX3 ! The KX3 is a superb piece of engineering In my circumstances as apartment dweller with very limited antenna options - WSJT modes allow me to still operate and make QSO's - thanks Joe Taylor! In other circumstances there wouldn't be an issue I envy your EME escapades! Enjoy! Dan VA3MA
