Defining Sub-bands

The band associated with a spot's frequency is determined by referring to a Sub-band Definition file. If the notes accompanying a DX spot do not specify a mode, then SpotCollector chooses the mode based on the spot frequency by referring to the Sub-band Definition file. A default Sub-band Definition file is included with SpotCollector; you'll find the pathname of this file specified in the Sub-band Definition panel on the Configuration window's General tab.

You can edit the specified Sub-band Definition file to better meet your needs using your favorite text editor, e.g. Notepad. After saving your modifications, click the Sub-band Definition panel's Select button, navigate to the modified file, and click the Open button; SpotCollector will then begin using the new definitions.

Entries in a Sub-band Definition file must obey the following rules:

* each line of the file defines a sub-band, sequentially specifying a lower-frequency limit (in kHz), an upper-frequency limit (in kHz), the default mode name, and the band name. The following four entries, for example, define 15 meter sub-bands:

21000,21070,CW,15M

21070,21110,RTTY,15M

21110,21200,CW,15M

21200,21450,USB,15M

* sub-band frequency ranges must be non-overlapping

* sub-band entries must be sorted in order of increasing frequency

* valid mode names are AM, CW, FM, LSB, RTTY, USB, and any mode defined in ADIF

* valid band names are 160M, 80M, 60M, 40M, 30M, 20M, 17M, 15M, 12M, 10M, 6M, 4M, 2M, 1.25M, 70CM, 33CM, 23CM, and 12CM
