This is TICOM report DF-105 ‘Determination of the absolute setting of the AM-1 (M-209) by using two messages with different indicators’.
‘DF-120 (TICOM 2794) makes reference to another document, TICOM 2795 "Determination of the Absolute Setting of the AM-1 (M-209) by Using Two Messages with Different Indicators".
Do you know if that document has been declassified, and if it is available anywhere?’

I don’t have this file but anyone can request it from the NSA’s FOIA office. If you do get it please share!
