Yaesu has just upgraded the FT991 to the FT991A which features a real time bandscope/waterfall-like on the Icom 756 series where the audio is not muted while the bandscope is going. So far I think it is the only HF/VHF/UHF rig to have one. Certainly makes it more attractive in my mind. See: http://www.universal-radio.com/catalog/hamhf/4991.html 73 John AF5CC
