Rudel_chw Posted March 3 Posted March 3 I understand that this sounds is heard when a radar locked target is detected by the R-3R missile, but I get the sound when the target is still around 10 Km away and the LNCH light on the ASP Optical Sight is not yet illuminated, and on the radar screen the LNCH light is also not illuminated. Is this normal behaviour? My belief was that the lock-on sound ahould be heard only once the Launch Authorization is attained. Will record a video to illustrate this better.

Here is a video where you can hear the tone: This is not an IR missile tone, as the aircraft is mounting no IR missiles, only the R-3R SARH Edited March 6 by Rudel_chw For work: iMac mid-2010 of 27" - Core i7 870 - 6 GB DDR3 1333 MHz - ATI HD5670 - SSD 256 GB - HDD 2 TB - macOS High Sierra For Gaming: 34" Monitor - Ryzen 3600 - 32 GB DDR4 2400 - nVidia RTX2080 - SSD 1.25 TB - HDD 10 TB - Win10 Pro - TM HOTAS Cougar Mobile: iPad Pro 12.9" of 256 GB
Schmidtfire Posted March 6 Posted March 6 My guess is that the R-3R seekerhead is detecting reflected energy from the locked target out of kinematic range, generating a tone. MiG-21 radar complex calculates when the target is within missile range, then gives pilot a Launch Authorization. This is from the Mirage-2000C update 18/11/2021: The Super 530D seeker is now simulated and will require to be locked on the target before the missile can be fired. This lock is indicated by a 650 Hz tone (same as the MAGIC lock tone) and by the missile status letter being circled on the VTH. The seeker range should be above the missile kinematic range in most cases but could result in bad surprises in look down scenarios. So it's possible that the same logic applies for a radar guided R-3R on the old MiG-21bis. Here is a very old tutorial from one of the all time greats, xxJohnxx. If you listen closely (difficult to hear), there is a tone when he is locked on, but out of range. So it's been like this from the beginning. That's my theory anyways, but maybe one of the developers can comment on this 1

Hi, Just saw the video and indeed it seems it was like this since the beginning. However, what generates a doubt on my case, is that the official manual states that the sound is heard when there is a radar lock, not before: 57 minutes ago, Schmidtfire said: That's my theory anyways, but maybe one of the developers can comment on this I can understand that the developers are focused on releasing the Corsair, so I don't expect any Updates or Improvements on the MiG-21 until after that release occurs, however I do expect bug fixing to continue, or at the very least an acknowledgement so that users don't get frustrated. It would be great to have someone from Magnitude comment on this, but at this point I no longer expect it to happen. I truly love this Module, but this kind of problems take a lot of enjoyment out of it, so much so, that I'm on the verge of moving on and take another Module instead for study Best regards and thanks a lot for the help.

Schmidtfire Posted March 6 Posted March 6 (edited) It seems like you actually pointed out the solution with the picture of the manual. Perhaps no need to doubt Highlighted in yellow: 1. When the missile head is ready, you will see a MHR (Missile Head Ready?) light on the radar screen and hear a lock sound. It's the Missile seeker head seeing the target. Next sentence: 2. When the distance markers enter the launch zone, the Light LAUNCH will become visible on the radar screen. So the event is divided in two stages: MHR light + Lock sound. Markers within launch zone -> Launch Light visible It's kind of confusing the way it is written in the manual. But I'm quite sure it is correct. Edited March 6 by Schmidtfire

Markers within launch zone -> Launch Light visible Agree, the problem at the moment is that both the MHR and the LNCH lights always illuminate simultaneously, while the Lock tone can be heard much earlier ... perhaps the bug fix would be to just make the MHR light and the sound tone to occur simultaneously For work: iMac mid-2010 of 27" - Core i7 870 - 6 GB DDR3 1333 MHz - ATI HD5670 - SSD 256 GB - HDD 2 TB - macOS High Sierra For Gaming: 34" Monitor - Ryzen 3600 - 32 GB DDR4 2400 - nVidia RTX2080 - SSD 1.25 TB - HDD 10 TB - Win10 Pro - TM HOTAS Cougar Mobile: iPad Pro 12.9" of 256 GB
