Figure 29: Main Menu, Combiner Setting
When the combiner is enabled on one channel, the second channel will automatically reflect this change.
Additionally, any parameter changes made by the user in one channel will automatically be made for the second
channel, from which the combined signal is partially derived. The only setting that can still be changed individually
when the diversity combiner is turned on is the channel frequency, which allows for frequency diversity to be
implemented. To illustrate the synchronization of settings, the second channel’s settings menu highlight bar will
mimic the navigation path being taken by the user in the first channel.
Note:
Whenever the Diversity Combiner is On, any changes made to the Frequency option (even with Frequency
Diversity On enabled) causes Modulation Scaling for
both channels
to be set to the same value. However, if Mod
Scaling was set to Locked when the Frequency was changed, Mod Scaling will change to Tracking.

Frequency Diversity (Available with Diversity Combiner)
The Frequency Diversity option allows the user to independently change the frequency of each channel when the
diversity combiner is On.
The FreqDiversity option is toggled On or Off using the Enter key on the front panel keypad.
If there are two channels, the Combiner is set to On, and Frequency Diversity is Off, the channels are updated
simultaneously.
