Hi, guys. I have a question about S-75M Dvina. Situation: I find a target, get it tracked in "PC" mode, then I switch transmitter off on block I-66 (However the load is switched to Antenna, not dummy) - target diseapers from I-32 beta-epsilon monitors (target is not jamming), but the system is still tracking it! Indicators on the I-88 block still show changing parameters of the target! I can even launch rocket and score a successful kill! How does the system track target without emmitting signal?
