QDX - output dropped from ~5W to ~2W


 

Hello list :)

last year I finished my QDX, and I still run it nearly every day :)

Yesterday I noticed the output is reduced by ~50%.
In the beginning it was ~5W on 20m, and ~4W on 10m.
Now its ~2W on 20m and 10m.

As all the stuff is at the attic I'm pretty sure nothing has changed there (same power-supply, same antenna, same cables, same W11-NUC).

Where should I look to? What should I do?

Thanks in advance!

Cheers,
Torsten
