> REMARKS FOR THIS TABULATION
>
> Revision date is 2014-11-30.
>
> This work does not describe the RU-series of receivers used in liaison
> service,
> usually with GO-series or GP-series aircraft transmitters.
> Liaison-service
> RU-series systems (after RU-3) have small design differences compared to
> command-service RU-series receivers. Most of these result from the later
> RU-series liaison receiver systems being designed to support either one or
> two receivers per system. That required changing the location of the AGC
> bias resistors from the dynamotor unit to the individual receiver.
>
> This work does not describe the use of the five receivers from in the
> SCR-A*-183/-283 series that were also used for:
> - Observation-service (SCR-A*-185)
> - Compass-service (SCR-A*-186)
> - Liaison-service (SCR-A*-187)
> - General-purpose (SCR-AA-192).
>
> Only receivers and associated components for command set service are
> addressed. The expanded set of coils that was issued for use in other
> service is not listed or described.
>
> Instruction books for 28 of the 35 listed systems are the source for most
> of
> the information provided here.
>
> The instruction books for 7 of the 35 listed systems were not available
> when
> this tabulation was compiled:
> GF-2/RU-3a, GF-4/RU-5a, GF-8/RU-13, GF-9/RU-14
> SCR-AE-183, SCR-AF-183, SCR-AP-183
> Some details associated with these seven systems were obtained from
> alternate
> or partial sources, or inferred from other documented radio sets in this
> series.
>
> This tabulation was compiled by Mike Morrow/KK5F (Athens, Alabama).
> Comments,
