NOTE
This supplement describes the RF-596-02 Preselector
Module, a microprocessor-controlled preselector which
improves the R F-590 Receiver's performance in strong
signal environments. This option consists of an R F-578
Preselector and the A 1 Interface PWB 10073-6400.
The A 1 Interface PWB 10073-6400 is used to convert
serial data from the RF-590 to parallel data for use with
the RF-578 Preselector or the 1920-1200 suboctave
filter. The RF-596-02 Preselector Module is the A 19
Assembly of the RF-590 Receiver.
