A KiwiSDR in NZ? Probably just a harmonic or an overloaded ADC.
It is, yeah, in Napier.
Cant find that signal on any other Kiwi's around Hawke's Bay.
Two or three times an actual MW broadcast frequency is often observed when very strong local transmitting stations are present.
In this case 3 x 1278kHz = 3834kHz
Sometimes these are actual harmonics being radiated by the transmitter, sometimes they are externally generated by objects such rusty wire fencing, that is rectifying and re-radiating signals, and sometimes they are produced somewhere in the reception chain.
Many times it can be a combination of all of the above.
Placing some attenuation, or better still an amplitude / frequency slope equaliser ahead of the affected KiWi can often help to minimise such problems.
