I just don’t see a problem here.

I've been working on QRP WAS on Topband for several years, and last fall was down to needing WV, SC, and VT.  All QSOs were CW, and made during contests. A major reason those states are tough to work QRP is that Topband ops stay up late during contests, but go to bed when the band closes to EU. Another is that if a station includes one RX antenna, it's beaming to EU.

I use WSJT modes a lot on 6M chasing grids, and last fall, started monitoring the 160M JT65 frequency. Over about five months, I logged (SWL) more than 950 different stations from every US state except VT, most VE provinces, all continents, and about 20 countries. A sked produced a QSO with a station in the WV panhandle. On an average night I copied at least 30-40 stations running JT65. Rarely did I hear more CW stations than I could count with the fingers of one hand. One night I made the only QSO with EU (an SM station) of the season, and running about 1kW; the dozen or so EU stations I logged (again SWL), are the only ones received here in more than three years! EU is not easy on Topband from NorCal.  And by the way -- all that JT65 activity is packed into about 2 kHz of bandwidth!

IMO, traditional topband operation IS a dying thing. How many OTs will deign to respond to a weak CQ from an op new to topband to provide encouragement?  How many of us find topband noise levels growing every year? How many of us take the time to chase down and kill the sources? How many of these sources are out of our control? How many of us have space for decent 160 TX and RX antennas?  I do --  three TX and four RX -- but I'm one of the lucky few. And my noise level increases every year.

K1JT's WSJT modes offer a solution to the noise issue, by their ability to decode signals 10-15 dB deeper into the noise than even the best CW ops can copy.  Many of us have fun on 6M making QSOs via meteor scatter using K1JT's MSK144.
