I am trying to use cross band SO2V with my new K4D. For instance, I have my VFO A set to the 20m band, and the VFO B set to the 40m band. A/B (or B/A) does not work any more as the appropriate band filters are not selected. (Split not working is somewhat understandable, but A/B not working is a bug in my mind.)
