Mini-Mixers (MMXs) are mixers that allow tuning a slice receiver inside of a foundation receiver. They can cover a range of +/- 3MHz from the center frequency of the foundation receiver. MMXs are created for the client when slice receivers are created. In other words, MMXs may not be created directly, but are created as a result of the creation of a slice receiver. For debugging purposes, the mmx command allows the operator to dump the contents of the MMX data table.
