The impression I am getting is that WSPR is going down in popularity whereas FT8 is going up. I was considering buying a dedicated multi-band WSPR TX and WSPR RX. I am having second thoughts.
WSPR needs less bandwidth (about 6Hz) than FT8 (about 50Hz) but WSPR is more sensitive by about 10dB. Maybe many cannot make use of this because of local noise. Also FT8 allows 2-way QSOs.
Last evening I tried 40m WSPR and FT8. On WSPR I spotted nobody, whereas on FT8 I spotted 12 stations in a similar period.

Hi Roger,
I still believe WSPR is a popular mode.
Have made WSPR transmitter using wemos D1 & Si5351 modules recently learning how to code.
I then found a WSPR board by a Online Radio club that goes ontop of a Raspberry pi and presented to our radio club one evening. Everyone was impressed and some of the newly licensed found out what WSPR mode is and were asking questions. So the club asked me to order boards and components.
Its going to the first club project of the new year.
