Regarding http://physics.princeton.edu/pulsar/k1jt/FT8_DXpedition_Mode.pdf This will kill the other digital modes and will finish off CW. Plenty a DXpeditions will appear, people on vacation destinations with semi or not rare prefixes, each on their own Fox frequency away from ‘normal’ FT8 frequencies. For the same some or many will become a fox with their home call for everyday work; FT8 contests will now with near 100% certainty be organized meaning that more designated spectrum of the other modes will be hijacked; People without SDR’s won’t be able to operate in the 2700 up to 4000 Hz spectrum; Ultimately what keeps one away from fox not answering 5 stations but e.g. 10 or more stations at the same time provided one has a performant PC and an SDR? I assume nothing. Some day may be not you but certainly someone else will break the open/not open code and provide that 10 or more station answering at the same time ability. All hell will then even more break loose on the bands; With FT8 Dxpedition's QSO rates I predict that even SSB activity will suffer. The high QSO rates (5 or 10+) over other modes will be favoured by DXpeditioners, more income from QSL cards, instant LoTW uploads and donations. Physics scientist and Nobel prize winner or not, I’d say think first doctor then act. PS To the point and on-topic replies please. For the hate mailers if you feel the urge, honestly I couldn't care less.
