A church nearby to my QTH decided to install an LED string to the church
steeple cross. The RFI was very bad on 160m.
The problem was a very dirty Hanley LED driver switch-mode supply. Replaced
with a Mean Well unit and now all is quiet.
I made a YouTube video showing the isolation, testing and solution. Some of
these LED drivers are EXTREMELY noisy, but they don't need to be!
