> This work does not describe the use of any listed receiver in liaison receiver
> service, such as used in SCR-A*-182, SCR-A*-185, SCR-A*-187, or SCR-A*-192
> systems.  Only the coils specified in the command set instruction book are
> shown.  The expanded set of coils that was typically assigned for liaison
> receiver service are not listed.
>
> Some systems were supplied on multiple dates and order numbers.  Those listed
> here are the earliest that I have found.
