S-75M3; Linebacker II; "Habu" flight...
After launching the first missile (missile guidance -method UPR; APP - method UPR) and Habu starts jamming, the lamp of tracking distance lit off, but still distance boresight is moving like in I-87T/T... Somethimes, when switch 150-75 mode it stops, sometimes not... I think, this is the same problem like Dvina "active guidance".
A question - what is the proper way to use RPK switch in SA-75M/MK Dvina?
