    * provides band navigation buttons with a 5-deep memory for each band and automatically save the current frequency and mode into the appropriate memory when that frequency remains unchanged for more than a user-specified time interval

    * displays DX spots (requires SpotCollector 2.7.3 or later)

 - displays the alternate VFO (VFO B or the Sub VFO)

 - expands multi-radio support from 3 to 4

 - makes the following parameters accessible via DDE (tnx to Ben PG5S and Larry N8LP)
   alternate VFO
   transmit frequency (primary VFO if not split, alternate VFO if split)
   radio status (receive or transmit)
   radio model
   radio name

 - includes substantially rewritten online documentation

Clicking the Main window's new Bandspread button displays Commander's Bandspread window, which provides a vertical slide rule dial showing range of frequencies around your radio's current frequency, and a Band panel containing an array of buttons corresponding to the 160m through 2m amateur bands. You can resize the Bandspread window both vertically and horizontally.
The Range panel determines the range of frequencies depicted on the slide rule dial. You can vary this range from 1 kHz to 100 kHz in six steps; your radio's current frequency will always appear centered in the dial.
Clicking on the dial will QSY your radio to the associated frequency. Double-clicking the dial will QSY your radio to the associated frequency and then reduce the range by one step, unless the range is already 1 kHz. Allowing the mouse cursor to hover over the dial will produce a small popup showing the associated frequency to which your radio would be QSY'd if you were to click or double-click.
Commander remembers the last 5 frequencies you visited on each band, and the mode in use for each such visit; this information is stored in a Band Stack associated with each band. If you QSY the radio, and then let it remain on a frequency for longer than the dwell time setting, the new frequency and mode will be saved on the appropriate Band Stack. The Bandspread window's Band panel contains a button for each band between 160m and 2m. Clicking a band button sets the radio's frequency to the most recent frequency used on that band, and sets its mode to the mode in use at that time; the Band Stack is then advanced, so that clicking the same band button a second time sets the frequency/mode to the next-most-recent frequency/mode used on that band. Using this mechanism, you can QSY to the most recent 5 frequencies.
The memory used to provide the slide rule dial and Band Stack are freed when the Bandspread window is closed.

Viewing and Selecting DX Spots
If SpotCollector (version 2.7.4 or later) is running and Commander's Bandspread window is open, then SpotCollector will automatically send to Commander spots of DX stations operating on the transceiver's current band that meet SpotCollector's current filter criteria (with the exception that wildcard characters in the Call and DXCC filters care not handled). Commander displays each DX spot on the Bandspread window's slide rule dial unless its age exceeds the specified lifetime. The size of the font used to display DX spots can be specified as a function of the slide rule dial range, making it possible to use larger font sizes with smaller ranges. DX Spots that are close together in frequency are separated horizontally to form a list of up to 8 spots; for busy frequencies and a long lifetime, it may be necessary to expand the Bandspread window horizontally to see all of the spots; alternatively, zooming in to a smaller dial range may separate the spots, or a smaller spot font size can be specified.
allowing the mouse cursor to hover over a DX spot displays a small popup window showing the spot's callsign, transmit frequency, QSX (listening) frequency if operating split, mode, UTC time last spotted, and spot notes
if a spotted DX station is not operating split, clicking its callsign in the callsign display will set the radio to the spot's frequency and mode; if the spotted station is operating split, then clicking its callsign will place the radio in split mode with dual watch enabled (if available), and the VFOs set to the appropriate transmit and receive frequencies for split operation
 double-clicking a spotted callsign sets the radio to the spot's frequency and mode as described above, and then reduces the slide rule dial range by one step, unless the range is already 1 kHz.
When the radio QSYs from one band to another with the Bandspread window open, Commander clears the DX spots from the slide rule dial, and SpotCollector sends Commander each Spot Database entry on the new band that meet its current filter criteria (subject to the above-mentioned wildcard character limitation). Thus Commander always displays that subset of SpotCollector's filtered Spot Database entries that are operating in the range of frequencies shown on the Bandspread window's slide rule dial
The memory used to maintain and display DX Spots are freed when the Bandspread window is closed.

Commander 5.1.1 is available via www.qsl.net/dxlab or via this reflector's Files area.
