Dude, if U are using a SDR that could be a " birdie" also called a spur. I have that issue with my SDR and it gets worse at night when signals are strong.
Hey Dude,
Let me present an opposing view:
1) All these different people located across a wide area, all using different receivers (different manufacturers thus different designs) are hearing it. That says that it is very unlikely to be a spur generated in a receiver. These sorts of spurs tend to be particular to a certain make and model of receiver and can be location specific - it all depends upon the input IP3 (
https://en.wikipedia.org/wiki/Third-order_intercept_point) of the receiver circuit and the input level at the receiver input, thus a function of the the circuit, antenna, location, propagation, etc. A Sony ICF-xxxx will have a different input IP3 than a Drake, etc. and then the spurs will show up in a different place. Pretty unlikely that everybody will have the same type and level of spur.
2) It's unnecessary since WBCQ has admitted to doing it at this point, but someone could also do TDoA on the Kiwi network and if the algorithm resolves to a location, it's also very unlikely to be a spur in the Kiwi SDR.
