I received my 6400 (no knobs) about a month ago and things are working great and I am making contacts. After using the radio I now understand why people like knob radios. Smart SDR does not provide a way to store all radio settings as one would expect. When you leave a knob set or a menu setting set it stays there in analog radios. The mic and TX profiles make sense but the Global profile does not. In my operations I operate SSB CW and FT8. I would like to make a global profile for each of these modes covering all bands so when loaded I have a know configuration and don't have to remember to tweak the power for the linear or remember to set the tune step or turn on the NR or set the sideband to name a few. Looking at the list of stored items for global profiles shows that only a select few items are stored. Changing bands in WSJTx to 40 or 80m always requires me to set USB because the radio always reverts to LSB on these bands. It would also be great if one of the user generated global profiles could be set as default and loaded at startup. I see a number of other posts that talks about similar issues. I'm just adding my two cents to the pile. Lets hope these issues have some priority just because of the number of posts I see. Otherwise electronically the radio is some great engineering!
