1-14. An RCS-4B may be supplied with a Unit 2, HF Receiver either part number

4028-1000 or 4028-1100. These units are fully two-way interchangeable, and the

different part numbered module within the units is also two-way interchangeable.

The different part-numbered module in the 4028 unit is Sweep Synthesizer Assy,

either 5030-1001 or 5030-1101.

1-15. Unit 1, 6025-1000, of the RCS-4B may include a standby battery supply

assembly that is either a rechargeable type (P/N 6025-1018) or non-rechargeable type

P/N 6025-1008). These different part numbered assemblies are not interchangeable.

Specific information on the battery supply is provided in paragraph 2-21 and 4-53.

1-16. AIRCRAFT INSTALLATIONS. For airborne applications, the RCS-4B is

supplied with a special aircraft installation kit. Aircraft installation using this kit

is described in paragraph 2-10.

1-18. The RCS-4B receiver requires an antenna capable of efficiently receiving HF

signals from 2 to 30 MHz. Best measurement results will be obtained if the RCS-4B

receiver uses the same antenna as is used for the communication receivers. The 6043

power divider (supplied with the RCS-4B) provides for connection to three antennas

with power divided to the RCS-4B and up to three communication receivers. The

RCS-4B accepts a 50-ohm unbalanced signal input. If a balanced feed antenna is

used, a suitable receive balun should be installed. Test equipment required for

fault isolation and servicing of the receiver is listed in table 5-1.

1-19. SPECIFICATIONS

1-20. Table 1-1 lists the performance specifications for the RCS-4B receiver.

Performance data are base-d on the standard system configuration.
