I swear, there's about a billion posts in the digital forum that are some variation of "I can't decode FT8 signals."
Well over half of them resolve with: "Install Meinburg, Dimension4, or JTSynch to get your PC's clock accurate enough for FT8, because the default Windows' time management isn't good enough".
K0UA has helped a lot of hams get going on FT8 by personally answering their questions on the phone.
Maybe he should be invited to write this post? No one would be better suited.
