S 31 a 8A A 74 A 00 N P -- 74 is the level of the current programm (89,3) from the TEF
S C2 a 87 a E2 a 3C N P -- AF Bit enabled (the 8 from 87!) - 7E2 is the freq to check 90,2 (level, USN and WAM is written into TEF's latches)
S C2 a 87 a D0 a 3C a 88 a 01 N P -- switching back to 89,3
S C2 a 87 a D0 a 3C a 88 a 00 N P -- switching back to 89,3 (2 lines for faster tuning - switching from wide band to dynamic band)
S C3 a 5A N P 
S 31 a AA A 24 A 53 N P - reading the TEF now contains the level from the AF check (!) = 24 
S C3 a 5A N P 
S 31 a 8A A 74 A 00 N P - reading the TEF contains our old programm again (89,3) with level 74
