472kHz WSPR

Last evening and overnight until breakfast I was on 472kHz WSPR (5mW ERP). Yet again, very few spots received (4 uniques) making 472kHz hard work.

The noise floor is going up at most RX stations. As an example my own RX noise floor was S1 on 472kHz. It is now S8 with the PC I bought a year ago on its SMPSU. Sadly, this is fairly typical and RX stations are struggling more now. QRP is harder than it was even a few years ago, especially on LF, MF and lower HF. Luckily my noise floor is OK on 10m upwards into VHF and UHF, although I know others struggle.
