I'd venture a guess that they had RSBN/PRMG receiver removed. RSBN is Soviet/WaPac TACAN equivalent while PRMG is analogue to ILS with alleged cat II capability. However, for the time being it is not confirmed that Smolensk north had either RSBN or PRMG transmittear installed and operating. Seemingly it rather relied on NDB/PAR.
May I have the link to Sverdlovsk forum, to confirm my suspicions, please?
