Doppler radio direction finding
- ... that Doppler DF uses the Doppler effect to measure the bearing of a radio transmitter, although neither the transmitter nor receiver have to be moving? Moell, p.21

- Reviewed Avrodh the Siege Within
Article is quite jargon heavy. I think the hook is interesting, but wonder if it will be to someone less familiar with the jargon. I have concerns about the sourcing, as the first source I checked (Sadler 2010, p. 4.) doesn't support all of the text attributed to it. The article should be checked to ensure everything cited is actually in the sources. It could also use some diagrams to aid with the understanding, much like the Sadler source uses, although the DYK nom won't hinge on this. CMD (talk) 06:59, 23 August 2020 (UTC)
- Alt 1 ... that Doppler radio direction finding is capable of measuring the direction of a stationary radio transmitter despite the Doppler effect being a phenomenon of movement?
- Hi Template:U are you still reviewing this? VincentLUFan (talk) (Kenton!) 06:34, 12 September 2020 (UTC)
Sorry, two weeks at the cottage and start of school. I'll get to this shortly. Maury Markowitz (talk) 15:01, 13 September 2020 (UTC) Alt1 works for me. I have no diagrams to add, and that should not hold up a DYK. All else appears fine? Maury Markowitz (talk) 21:27, 14 September 2020 (UTC)
- Template:U, "article is quite jargon heavy". Maybe you can discuss with Template:U about this. VincentLUFan (talk) (Kenton!) 10:59, 21 September 2020 (UTC)
- Template:PingI made a number of minor edits to gr, but to be honest, this is not particularily jargon heavy and most of the terms do have inline explainations. Maury Markowitz (talk) 14:58, 21 September 2020 (UTC)
- Template:Ping I've made some touchups, can you have another look? Maury Markowitz (talk) 14:58, 21 September 2020 (UTC)
- I brought up sourcing, and specifically mentioned Sadler 2010, p. 4. This has been edited a bit, but Sadler is still used to source "The operator rotated the antenna looking for points where the signal either reached a maximum, or more commonly, suddenly disappeared or "nulled". A common RDF antenna design is the loop antenna, which is simply a loop of wire with a small gap in the circle, typically arranged to rotate around the vertical axis with the gap at the bottom." The text on p.4 is "Traditional approaches to DF – directional antenna, Simplest approach for DF is to mechanically rotate a directional antenna, A peak in the response indicates the approximate signal direction, Not easy to rotate directional HF antennas due to large size, Can use an electrically small loop, Not high accuracy, Problems with polarization – no good for skywaves, 180° ambiguity, Only needs a single receiver, Loop rotated so that the signal is nulled." The source relates to the text, but it does not seem to be the basis for the text. There's quite a bit in the text which isn't in the source. Most sources are offline so I can't check them, but Bauer shows similar issues, and is further reportedly accessed in January 2008, which feels unlikely. CMD (talk) 12:29, 22 September 2020 (UTC)
- The diagram on page 4 shows an antenna consisting of a loop of wire being rotated to sense the null. I added "arranged to rotate around the vertical axis" because it's not obvious from the diagram, although it is on the next page. But that's fine, there's a better diagram in Hunting.

A new reviewer is needed as CMD hasn't edited since September 26th and did not respond to pings. Narutolovehinata5 tccsdnew 11:37, 3 October 2020 (UTC)
Lua error: expandTemplate: template "y" does not exist.
Note: edit conflict. I had just spent an hour writing the following, so I'm adding it anyway. Thanks, Hawkeye! Storye book (talk) 20:28, 14 October 2020 (UTC)
