According to the new ITU WRC-15 Allocation per 01-01-2017 it is not longer permitted for some countries
to transmit below 5351.5 kHz. See WIKI
This means for these countries that the official WSPR Dial frequency of 5.2872 is no longer in use for transmitting.
On experimental base an alternative WSPR Dial frequency of 5.3647 MHz is in use.
It may be worth to be QRV at that frequency.
