DIGITAL MODULATION (OPTION UO1) 

Overview 

NOTE 

Digital modulation is available with Option U01. 
 

 
Pressing the MOD key opens the modulation menu. The 

Enable 

key applies the 

currently selected modulation type; indicated in the 

Type

 parameter window. The 

MOD key will become illuminated when the modulation is activated. 
The modulation menu contains all the editable fields for setting and activating 

modulation. Digital modulation settings are constructed across up to four pages: 
-

 

General setup options are shown with the selected modulation type in the 

navigation bar, e.g. 4FSK:
