SPO-10 no lock on signal

[Alireza.kh]

since 2.9 i noticed that there is no warning signal sound when the fighters or SAM locked on us.

In a newsletter a few weeks ago ED announced that they are Re coding SPO-10 to be more realistic, adding many new features that haven’t been in DCS before. So it’s safe to say that you don’t need to worry, soon we will have the most realistic SPO-10 in a consumer simulation

 “The updated SPO-10 RWR will consist of four channels with completely independent processing, the same as in the real system. The radar detection calculations are physics based, they calculate the radiation pattern of the transmitting source, the sensitivity of the receiving antennas, and the transmitting power of the emitter. This translates to detecting low-power radar emitters and shorter range and vice versa. Detection range will also vary based on bearing to the emitter source. For certain radars, the range can also be judged based on how frequent the detections are. The system will now only detect emission sources within the operating frequency range of the RWR. For instance, early warning and search radars and some other radar types will not be detected.”

yes i read that and it will be a useful feature. but until that update a hotfix is needed.

It’s been two years, it’s not a directly important piece of equipment to the to ground mission, I think we’ll be okay waiting for them to put all their effort into the most realistic implementation  

For all we know, SPO-10 new modeling could come out next patch. The newsletter didn’t say it was far away, but mentioned it with Petro updates we got last patch

after the patch SA-8 radar lock signal got fixed. but still we get no warning from some SAMs. i tested all of them and with these SAMs we get no warning:

 ZSU-23-4 Shilka, Vulcan M163, SA-2, SA-5, SA-15 Tor, SA-13 Strela, Patriot

are not these within range of SPO-10? or simply game bug?

because in mig-21 i could receive warning from all of them.

MiG-21 SPO isn’t modeled with the limit of frequency range, it sees everything that is radar

When I looked it up, SA-2/SA-3/SA-5 radars are all too low frequency to be in range. But these SAMs almost always used very low frequencies because frequencies that are lower travel farther 
 

Patriot radar is definitely out of frequency range 

For SA-13, its radar isn’t modeled, if it was modeled it would still be out of range. Shilka radar is in Ku band, which means it could be in range or not depending on what side of the band it’s on. 
 

Idk about Vulcan, hard to find info on its radar, same for SA-15 Tor

Sa-3 give warning, it use I band and it is in range. SA-5 and SA-15 are also H band , should be in range. and yes Shilka use Ku band should be in, the C-RAM give warning and i guess it use Ku too. it need confirmation by ED.

There’s also the 740-8,000 PRF range in addition to 7.5-16.6 GHz carrier frequency 

For fan song for SA-2, I see it in E/F/G band, which is below the 6.6 GHz minimum frequency.
