Sunday plans

 Probably 500mW 10m WSPR and 5W 6m FT8 later.

WSPR?

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.

ZachTek WSPR transmitter

These are handmade in Sweden, although there is a Chinese rip-off that is available for much less. I think if files are available on the internet there is always a danger of this happening. 

I am not sure what protection registering the design gives, but I guess it must offer some help.

As I understand things, the Chinese rip-off does NOT contain switchable low pass filters, so the harmonic output is unlikely to be very good.

100mW 15m WSPR (Saturday)

For a complete change I am trying 15m 100mW WSPR.

UPDATE 1117z:  Just 6 spots from a station in Austria.  These days, although less sensitive,  there seems to be far more activity on FT8  than WSPR.

UPDATE 1212z:  Still just 6 spots of me from OE3GBB/Q (1233km). If I was starting out, I think you are more likely to have success with QRPP on FT8 rather than WSPR. QSYed to FT8.
