13.5.2.

 

Radio M&C 

The RS-232, RS-422, or RS-485 (depending on configuration) Radio M&C signals pass from the BDE computer 

through the RF M&C port of the base modem and are modulated and demodulated.  These M&C signals are 
diplexed with the Pedestal M&C signals before passing through to the above decks modem.  The Pedestal 

modem then converts the RF Signal back to RS-232/422/485, before routing to the M&C port of the above 

decks radio equipment via an interface cable.

 

13.5.3.

 

Channel Identification 

There are four base frequencies used in the 400MHz FSK modem assemblies:   

•

 

The BDE Modem Transmits Pedestal M&C at 452.5 MHz  

•

 

The BDE Modem Transmits Radio M&C at 447.5 MHz 

•

 

The ADE Modem Transmits Pedestal M&C at 465.0 MHz 

•

 

The ADE Modem Transmits Radio M&C at 460.0 MHz
