As a complete unit, they are fully two-way interchangeable. With one exception,

module assemblies within units are also two-way interchangeable. The different part

numbered modules used in the units and their interchangeability are as follows:

1-16. Proper operation of the TCS-4B transmitter requires use of a broadband HF

antenna which is not supplied. No damage to the TCS-4B will result if a narrow-

band antenna is employed. However, the received signal power vs. frequency at

the RCS-4B receiver may be so limited by the transmitter antenna radiation loss that

an accurate picture of ionospheric propagation conditions may not be possible. All

cables to connect the TCS-4B to the antenna must also be supplied. The TCS-4B

employs a type HN connector for RF output. All connectors and adapters from the

HN output to the user's antenna cable must be supplied. Test equipment for servicing

and fault isolation of the TCS-4B are not supplied. Recommended items are listed

in Section 5.
