Beamscanner Posted August 24, 2017 Posted August 24, 2017 Squadron: VFA-211 Base: John C. Stennis (CVN-74) Location: en-route to (or already in) the Persian Gulf Time: Feb 2002 Mission: Carrier ops Starting at 43 seconds you can hear a few different emitters coming from the RWR in the video. These emitters are likely from the Carrier itself. This probability is reinforced by the fact that the RIO moves the camera to look at the radars themselves at 1:37. This is 'Constant' (otherwise known as raw, PRF, threat, emitter) RWR audio. Wikipedia suggests that VFA-211 had F-14As at this time, which would imply that this is raw audio from the ALR-45. If its the F-14B, then it'd be audio from the ALR-67. https://en.wikipedia.org/wiki/VFA-211_(U.S._Navy) 1
RaceFuel85 Posted August 24, 2017 Posted August 24, 2017 Yes, at that time VF(A)-211 were in F-14A's. They went on their final F-14 cruise in 2003 and transitioned to the F/A-18F in 2004.

Beamscanner Posted August 24, 2017 Author Posted August 24, 2017 (edited) I wonder if Heatblur has unique radar audio planned like they did with the viggen..? I know other devs have refrained from it since documentation that explicitly details raw audio is nearly impossible to come by. In some cases manuals only talk about synthetic audio, because thats the only audio difference between RWRs. More on that here: https://forums.eagle.ru/showthread.php?t=171083&page=4 Heatblur did say that they had "rare" reference material for the radar and RWR. thank you so much! No problem!! I save all RWR videos I come across. They are jewels hidden in the ruff Edited August 24, 2017 by Beamscanner
uboats Posted August 24, 2017 Posted August 24, 2017 yup, it's rare. anything related to rwr is sensitive will adjust the sound effect of rwr later [sIGPIC][/sIGPIC] My DCS Mods, Skins, Utilities and Scripts | Windows 10 | i7-4790K | GTX 980Ti Hybrid | 32GB RAM | 3TB SSD | | TM Warthog Stick | CH Pro Throttle + Pro Pedal | TIR5 Pro | TM MFD Cougar | Gun Camera: PrtScn |

Naquaii Posted August 24, 2017 Posted August 24, 2017 Unfortunately that is most likely not RWR audio but instead interference in the camera itself from the radar emitters. The rwr did not have an external speaker so unless it was plugged into the ics system a camera like that would not hear them and it doesn't seem to be as you can't hear anything else from the ics, only cockpit noise. This seems to also be confirmed in the comments to the youtube video. The F-14's ALR-45 and ALR-67 used/uses standard warning tones, not sounds generated from the characteristics of the received pulses. This functionality instead was found in the electronic warfare suite (most likely related to the jammer) and could be listened in on by the RIO via a separate switch. That audio would be much more like the Viggen's rwr. 2
Beamscanner Posted August 24, 2017 Author Posted August 24, 2017 Unfortunately that is most likely not RWR audio but instead interference in the camera itself from the radar emitters. Seems pretty clear for interference, though I guess they are pretty close to emitters. :( My parade is ruined!

Naquaii Posted August 24, 2017 Posted August 24, 2017 On page 19-7 of the F14AAP-1 there is a "Glossary of tones" table which lists the ALR-67 and AN/ALQ-126. It mentions that the ALR-67 has a low to high frequency tone determined by scan rate and prf of threat radar, so the prf affects it but it isn't raw prf. The AN/ALQ-126 is listed as having raw prf sound though. The ALR-45 is listed as having the same tones as the ALR-67 in the earlier versions of the F14AAP-1. It is a difficult matter to find good reliable info on, for natural reasons! Unfortunately as there is no speaker in the cockpit for these systems a recording of these would somehow need to be patched into the ICS. Still a nice video though! :-)

The AN/ALQ-126 is listed as having raw prf sound though. The ALR-45 is listed as having the same tones as the ALR-67 in the earlier versions of the F14AAP-1. So it has several different synthetic tones to choose from based on PRF and Scan? So like it has a tone for pulse radar equipped fighters(low PRF, sector scan) Pulse doppler fighters(med-high PRF, raster scan) pulse SAMs(low PRF, quick scan/no scan) pulse doppler SAMs(med-high PRF, quick scan/no scan) search radars(low PRF, long scan) ?
Naquaii Posted August 24, 2017 Posted August 24, 2017 (edited) Yeah, that's possible, problem is that it's a very broad reference so could mean quite a few different things. Could also just be a reference to having a threat library to identify different emitters and categorise them as that would work by comparing parameters as those. So it could very well just be that it means that it has something very similar to the current A-10 and F-15 in DCS. What I do like about the F-14 is that it seems like we have the choice between a more f-15 and a-10 like implementation (at least the ed-versions) and one which is quite like the ajs-37.

Beamscanner Posted December 3, 2017 Author Posted December 3, 2017 (edited) I think there might be some ALR-67 synthetic audio in these videos, if you were still looking for something. (a lock-on tone?) (11 seconds in, 'new guy' audio?) (and yes i realize this is a different aircraft. But it uses the same ALR-67) Edited December 5, 2017 by Beamscanner
