slundal Posted February 28, 2017 Share Posted February 28, 2017 Did this as much for my self as well as for everyone else who wants to study the different signal coming from the RWR. There is a complete list of aircraft and ground installations tested in the video description so you can jump back and forth and have a listen. Hope you guys find this useful! :) 2MFFyElZFWE Link to comment Share on other sites More sharing options...
Knock-Knock Posted February 28, 2017 Share Posted February 28, 2017 Cool, thx slundal. I have been thinking about something to train the ears with. If I remember correct, the tone frequency used for the RWR, is the same as which the given radar transmits at. So with a simple frequency modulation tool, and ELINT database, it should be possible to quickly recreate the signales. A simple but easy interface, be it a standalone program, or web based stuff, with just a quick hover over the given source / button. Im not capable of making such a thing, but have been wondering how something could be done - I have no programming skills. - Jack of many DCS modules, master of none. - Personal wishlist: F-15A, F-4S Phantom II, JAS 39A Gripen, SAAB 35 Draken, F-104 Starfighter, Panavia Tornado IDS. | Windows 11 | i5-12400 | 64Gb DDR4 | RTX 3080 | 2x M.2 | 27" 1440p | Rift CV1 | Thrustmaster Warthog HOTAS | MFG Crosswind pedals | Link to comment Share on other sites More sharing options...
renhanxue Posted February 28, 2017 Share Posted February 28, 2017 RagnarDa linked onlinetonegenerator.com in the ELINT thread, if you want to play around :) To clarify, the tone you hear is the same frequency as the transmitting radar's PRF (pulse repetition frequency, that is how many pulses or "packets" the radar sends per second), not the frequency of the carrier. Your average air search radar operates on the S-band (2-4 GHz) and fighter radars are usually on the X-band (8-12 GHz, ish), and you obviously can't hear that. If the PRF is too high/too low to be reasonably audible, or if the transmitting radar isn't a pulse radar (continuous wave radar is a thing), you get an arbitrarily chosen tone instead ("ambulance siren", IIRC).

lemoen Posted March 1, 2017 Share Posted March 1, 2017 This is cool. One comment. It would be much butter if you can cut out all the mission editor bits and just have the tone with the radar name. Play each for 5s or so. This will shorten the video and also make it easier to compare the different tones. Link to comment Share on other sites More sharing options...
BravoYankee4 Posted March 1, 2017 Share Posted March 1, 2017 Hm... thinking of building a gadget based on an Arduino micro and a little tweeter for this :) Link to comment Share on other sites More sharing options...
ward8124 Posted March 1, 2017 Share Posted March 1, 2017 Thanks for posting. Some more feedback, agreed with Lemoen. If we can get the video without commentary and shortened that will speed our "Ear training" up. Also, please include missile warning tones and launches too please. Great work none the less and something I've been trying to understand more. EVGA GTX1080TISC2 Black Hybrid Cooler, Asus Strix X399, Water cooled ThreadRipper 1920X, Dominator 32GB 3200Mhz,NVME Samsung 250/500GB SSDs, Corsair Air 740 case, Acer Predator 34' Gsync curved display + 3x Alienware 23inch 120hz monitors. TM HOTAS, RAZER - Tiamat,Blackwidow, Mamba, Tartarus and Oculus Rift CV1/DK2 + TrackIR5, MFG crosswinds Oh and a very understanding wife. Link to comment Share on other sites More sharing options...
grunf Posted March 1, 2017 Share Posted March 1, 2017 The MiG-21 sound you heard is actually a lock sound, or rather two sounds, 3400Hz and 5400Hz, 0.2 second on, 0.5 second off. Its search radar sounds exactly as the one of M2000C, 1000Hz, 0.5s on, 1.2s off. Link to comment Share on other sites More sharing options...

But yeah I know, didn't plan that far ahead when I made the video. Might make a revised one in the future. :) Link to comment Share on other sites More sharing options...
