Functionality of the Mercury6e

49

For example: In the NA region, setting a frequency of 902,999 kHz results in a
setting of 902,750 kHz.

When setting the frequency of the module, any frequencies outside of the valid range for
the specified region are rejected.

Frequency Hop Table

The frequency hop table determines the frequencies used by the M6e when transmitting.
The hop table characteristics are:



Contains up to 62 slots.



Valid frequencies for the region currently selected.



Changes not stored in flash, thus changes made are not retained after a power cycle

or a restart of the boot loader.



Inability to change individual entries after uploading without reloading the entire table.



Frequencies used in the order of entries in the table.

If necessary for a region, the hop table can be randomized to create a pseudo-random
sequence of frequencies to use. This is done automatically using the default hop tables
provided for each region.
