Talk:NDB beacon signals
Probably some noise from a running motor. Crossband (talk) 23:03, 24 October 2016 (NZDT)
- A motor emitting intermittent CWContinuous Wave? Among many things that are not a motor, this is likely some device directly related to RFRadio Frequency electronics creating harmonics, could be another receiver at the OP's shack, for example a hand-held scanner with battery saver at the lowest setting (highest duty cycle). I have a crappy Alinco DJ-X11 with oscillators emitting RFRadio Frequency all over the place in up to 30ft distance, creating nicely puzzling pseudo "beacon" (=intermittent) CWContinuous Wave signals.
Please rename this and move this to the unidentified section. Yalek Ywsia1.
this is MPT1327 _arclamp
Actually this is NDB beacon for ONL - o'neill airport Mikideez (talk) 23:18, 22 October 2023 (NZDT)
Mikideez, are you claiming this NDB was picked up over 7,000 kilometres away? OP is in Brussels, Belgium but ONL is in Nebraska, USA --Goliath (talk) 18:04, 1 January 2024 (NZDT)
NDBs can be received very far away when conditions are good. However, ONL is probably Liege on 290 kHzKiloHertz (kHz) 10^3 Hz. See:

The O'Neill airport doesn't even have an NDB listed there, although it may still have one. The VORTAC beacon is on the VHFVery High Frequency (30-300 MHz) band.
You can use OurAirports database to identify many NDBs. Otherwise, try google for NDB + ID + frequency.
This is not RFRadio Frequency interference, not MPT1327, and this signal is not really unidentified. Only the source was.
