[VHFcontesting] Thoughts on the Digital Modes and VHF Contesting

To be transparent re the "/R" issue and WSJT-x, I can see how some operators might be ok with the current functionally vis a vis "/R".  That being said I'm not enthused about it and I don't really want to get into more detail on this list.   I'd encourage people contemplating using WSJT-x while roving to try this out ahead of time and form the own conclusions and at least be aware of how things work.   

I'm offering my comments re this matter to outline one of the reasons why I as a rover am not enthused about using modes such as FT8 while roving.   I believe I have outlined my views re this functionally this to the WSJT team in the past.  To recap I am grateful to have access to WSJT-x and appreciate the efforts of the developers.  I'll continue to look at the "/R" issue going forwards.
