630m WSPR general shows a lot of bogus decodes in the last 24 hours list
I striped non plausible locators decodings.
I have good receiving results but it is very rare to get over the 8000km barrier here.
The best DX seen here is ZF1EJ a little over 8000km
K9FD BL11je is only once? seen in EU by LA2XPA
while VK4YB QG62 is never copied in EU possible also because the wrong TX times?

Listening with headphone on the Flex1500 QRN level is high constant cracking sort of thunder storm QRN seems not to hurt WSPR decoding.
The 24*7 drifting hum QRM possible originated by solar power converters that insert power in H.V. transformator stations . Can be 50kM or more away
474.3 in the 630m band just below the DX window
S9+10 on Beverage in JO33hg
in the P-SDR receive window below it shows like drifting carriers.
the geen line indicates the WSPR decoding window 475.600 - 475.800 kHz
sounds like here:
https://youtu.be/YgDhRYLkAyI
This Powerline QRM is slowly moving into the 475kHz band it is not only the carriers but also high noise
Receiving of weak signals will become very difficult in all bands in future.
A lot of the solar PV-inverters produce high noise . The institute KEMA we use to have is ended
Our Government need to save .. Never the less the amount of tax money needed is never enough.
For less service.
