In the morning I always listen to the radio in the bathroom and I notice that around 5:30 am the signal weakens considerably and a French radio station comes in that gets stronger and stronger. After about 20 to 30 minutes you have the French station completely and in reasonably good quality and nothing can be heard from the other station. This doesn’t happen every day, but it happens very often every week. How come?
The frequency is still on the correct MHz.

It is a pity that I have so little information about your question: do you live close to the French border, or near Wallonia?
I assume you are listening on the FM band. In that case, the time of day, weather conditions, etc. do not really affect reception. The latter is the case, and to a large extent, on the long, medium and short wave bands. But for the FM band, there are very few phenomena that affect reception, and they certainly don’t happen every day.
I see two possibilities. Or there is a French-language channel that broadcasts on exactly the same frequency as that of the station you are listening to. But that chance is small. I rather suspect that you have to look for the fault in the … imperfection of your radio. Due to the operating principle of most FM radios, they are also more or less sensitive to transmissions on a different frequency. Why that is so is rather complicated. I would try with another radio in the same place, see if you find the same phenomenon.
If that doesn’t fix it, I’d like to help you further!
