Talk:Unknown "whistle" signal on 49m broadcast band
Could be a pirate beacon, but could also be RFRadio Frequency interference from some electronic device which cycles like this. Note that the interval between "whistles" is not constant.
Someone with knowledge of pirate beacons may identify this if the frequency matches any known pirate beacon. Vhf explorer (talk) 05:31, 27 August 2026 (NZST)
On a second thought, perhaps this is not RFIa specific subset of electrical noise on the Electromagnetic interference (EMI) spectrum if it's heard on the exactly same frequency on many webSDRs. Unless Kiwi SDR itself creates this kind of RFIa specific subset of electrical noise on the Electromagnetic interference (EMI) spectrum. Also if this is affected by propagation effects then it's not local RFIa specific subset of electrical noise on the Electromagnetic interference (EMI) spectrum.
