One of my buddies is selling his 847, but it's one of the unidirectional models. Will I still be able to take advantage of doppler tracking and digital modes with it? Or do either of these require bi-directional CAT control? I'm not too pressed about seeing the frequency on the screen, just about it actually controlling the radio. Needless to say I've been spoiled with USB CAT control with my 7300 for some time now.
