obtained in the middlc of the core thread length and maximum output will be obtained at both sides of
the true null point. Slowly and carefuily turn the core to obtain minimum output.

A-m i-f alignment can be eliminated except
when necessary. The ceramic filter CFT is factory
preset and if transformer IFT Al is shielded by
shield case. The intermediate frequency of the set is
characterized by the ceramic filter because a ceramic
filter has a peculiar vibrating frequency which depends
on its size.
