If it's RFI one needs to know frequencies, Az & El, antenna beamwidths, measurement bandwidth, absolute time (not samples) between events etc.etc.<br /><br />Are there nearby radar stations, airports etc?<br />Non-obvious sources. e.g. do you have a car park gate using a microwave sensor?<br /><br />Is there a PLO in your downconversion chain that's lost lock and is searching?<br /><br />This has obviously gone on over a long time period. Is it via one antenna or an array?<br /><br />Lots of questions, but this kind of thing is my forte.
