Re: [RFI] broadcasting interference

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.
