I think it is for changing the frequency of the radar. One for peace time, and one for war.
Vympel is right. The switch has 3 positions (from botom to top) - "Lambda 2", "Lambda 1" and "Auto". The greek symbol λ "Lambda" is used to name the wavelenght. As frequency is the speed of the wave travels/wavelenght, with wavelenght changing and speed = const, the result is different frequency...
It has no effect in the sim as far as I know. In real life it is used so potential enemys dont record your frequency and do a better job of jamming the radar in event of a war.
This video is nothing spectacular. I just want to show how to set up parameters to find that F-117. Btw. I did not switched off transmitter after I have found the target - that was mistake and only IRZ saved me. Not to mention that I should not switch on and off transmitter so repeatedly but I should use dummy thing instead.
why do we need to switch the transmitter off after tracking a target? how will the missile hit it's target?
and how does changing the antenna mode from operational to dummy might help me?
Switching the transmitter to the dummy load has the same effect as switching it completely off: It stops transmitting. Which means that it doesn't provide a target for HARM missiles anymore.
1) Switching off and on transmitter in such repeated way can cause harm to the transmitter so I should use dummy load. 2) Switching off transmitter or use of dummy load needs to be done after several seconds or HARM can be launched against me. When I started to search for targets I used only several seconds scan - I should made one last turning off or use dummy load just before firing missile to minimize time exposed to HARM attack. Though I was very lucky - IRZ saved me in the last moment. Btw. my best results from Libya are when Wild Weasels are unable to launch single HARM despite my killing of three to four aircrafts.
Note variouse type of jamming - most of them not seen in SAMSIM!!!
Wow, how do you find such amazing videos?!
I've heard about these various jamming techniques, but I've never seen actual video of what it looks like!
It's also nice to see this upgraded SA-3, with some of the analogue dials digitally superimposed over the display. Maybe Hpasp could give us the option of having it too?
we can see how the missile pass near "Saman" target, without exploading. There was a comment in a forum, that this is due to the radiofuse, which cannot detonate agains targets with low RCS (the value mentioned was <0.3 m2, for "Saman" RCS is 0,36-0,51 for type 1 and 0,56-1,03 - for type 2) Saman
If that's true, it appears that Col. Dani used K3, or RCS of F-117 is bigger than uppermentioned...
In the end of this video: we can see how the missile pass near "Saman" target, without exploading.

The shape of F-117 and any other stealth aircraft is optimized to reduce the reflection towards the most probable observers, e. g. SAM and aircraft radars. This means that its RCS diagram will have not only deep gaps, but also a few sharp spikes, up to several square meters, or even tenths of square meters, in directions from which its illumination with such radars is highly unlikely. For example, if one would place a radar directly under the passing F-117, pointing towards the sky and illuminating it from below, its flat belly would create a very powerful return signal, on the order of several tenths of square meters. This means, that if missile would pass directly below, or above the F-117, its radiofuse would have no problem with return signal. There are also few narrow "bright spots" from other directions as well. On the opposite, if it would pass in the area, where its RF signal will be reflected to the different direction, it will most likely fail to detonate. I guess that Col. Dani had as much luck with this as with anything else. IIRC, his first missile failed to detonate, and only second did the job.
Also, the RCS of Saman is not that low, remember that mentioned values are for frontal RCS, not for the one from the side, where it will be much bigger due to reflection from its body and especially fins and rudders. My bet is that a failure to detonate was due to the faulty radiofuse - remember that the newest of these missiles were manufactured around 1990, and by the time of these trials have already exceeded their guaranteed shelf life.

I am agree with all your arguments, dear Lonewolf, I just wondering is it true, that missile radiofuse has dificulties against small RCS object (since I havent find such data). If true, and having in mind that Col. Dani hasn't idea what was comming against them, it appears he was really lucky (as no evidence of using K3 mode was mentioned from Z. Dani, nor in Anicic book).
Pity, that Hpasp is too bussy with doing a Christmass gift for Faroukh, Max and other childrens, and cannot help in this one...

Fully agree with your assumption.

The switch at the bottom right, I think Hpasp said before that it's for toggling between Automatic fuse selection, proximity fuse or command fuse detonation modes.
