Commander Online Help Contents
Radios differ in the degree to which they permit receiver bandwidth to be controlled from PC software. If Commander provides bandwidth controls for the current the radio Model, they are presented in the Filters panel on the right side of the Main window, sharing space with the Memory Bank panel; if the Filters panel is not visible, click the Filters & Devices button. Commander uses the concept of a Filter Group to bridge these disparate capabilities: a Filter Group is a named configuration of one or more receiver bandwidth settings. If Filter Groups are supported for a particular radio Model, Commander remembers the Filter Group last used in each mode. Checking the restore Filter Group on mode change box directs Commander to automatically restore the last used Filter Group whenever a new mode is selected.
Early Icom transceivers provide two Filter Groups, whose functions are hardwired: group 1 provides a wide bandwidth filter, and group 2 provides a narrow bandwidth filter. Later Icom transceivers allow the user to reconfigure one or both filter groups to a different bandwidth (by physical replacement, or in high-end transceivers via menu selection), and some include a third group ambiguously referred to as normal. The Icom Filter Group Names panel lets you assign names to each group that are meaningful for the actual filter configuration of your transceiver. With the radio Model set to an Icom transceiver, the Main window's Filters panel presents a Group selector with the choices whose names you've specified. You can activate a Filter Group by selecting its name in the Group selector on the Main window's Filter panel. When you change filters via the radio's front panel, the Group selector is updated to reflect your choice.
Commander's Filter panel provides comprehensive bandwidth control for the Yaesu 1000MP family, including the MarkV and MarKV Field. The Filters panel provides controls that allow direct selection of 2nd IF, 3rd IF, and sub-receiver filters. With the radio Model set to MP1000 or MP1000MKV, the Config window's Filter Grps tab lets you defines 12 Filter Groups, specifying a name, mode, 2nd IF filter, 3rd IF filter, and sub-receive filter for each; you can revise or delete these definitions, and provide new ones. You can activate a Filter Group by selecting its name in the Group selector on the Main window's Filter panel. When you change filters via the radio's front panel, Commander determines whether the new filter configuration matches a defined Filter Group; if so, the Group selector is updated to show the name of the matching Filter Group.
Commander provides mode-specific receiver bandwidth controls for the TS-480, TS-570D, TS-570S, TS-870, and TS-2000 as shown in the following table:
| Transceiver | SSB | CW, CW-R | RTTY, RTTY-R | AM | FM |
| TS-480 | High-cut, Low-cut | Shift, Width | Width | High-cut, Low-cut | |
| TS-570S, TS-570D | High-cut, Low-cut | Shift, Width | Shift, Width | High-cut, Low-cut | High-cut, Low-cut |
| TS-870 | High-cut, Low-cut | Shift, Width | Width | Width | |
| TS-2000 | High-cut, Low-cut | Shift, Width | Width | High-cut, Low-cut |
