Band Spotter

4-4 Band Spotter


The Band Spotter window shows spots close to your current frequency. The spot colors are determined by rules in the DX Spot Manager that set spot background colors. The band Spotter gets spot information from the DX Spot Manager, so the DX Spot Manager must be open. Spots from the current folder are used. For example, if you select the Inbox DX Spot Manager folder, all spots are shown. If you set up a rule to move spots to a different folder, you can select that folder to show its spots. To display spots, the folder must be a sub folder of the Inbox, or be a Band Edge folder.

Multiple Windows

You may open as many Band Spotter windows as you wish to monitor band segments, or provide views of the same band with different resolutions. Click VFO Hold on the Band Spotter toolbar to freeze the center frequency of the Band Spotter window so that the frequency coverage is held constant when you tune your radio. The settings for each window are independent.
