Hi Jorge,
Its best to ask a few other hams to run the same test at their QTHs.
You could be experiencing 10 kHz-spaced intermod products,
if thats the case they shouldn't show up at other QTHs. They
could be generated outside your QTH but distant from the
broadcast station

Hi Jorge,
I would first confirm the reception on a different antenna and receiver.
Also, see if it occurs every 10 kHz below 3500. It sounds like it might be
in their equipment. I recall a similar situation where there was a 10 kHz
oscillation in a power supply that was causing the signal to reappear every
10 kHz from the fundamental. Just guessing, however.
