The 1108 is supposed to have a sync detector not the 1105 as far as I can
tell.

Agreed. It does not even have SSB reception so it is highly doubtful that it
would have the complexity of a Sync-AM detector, and not promote that fact!
If it is actually making a heterodyne on each AM station as you tune it in,
it would seem to be defective. If it is only on some, then the tone is
probably caused by image frequencies from other stations - a weakness of the
receiver design.
