Mult Chaser is a free add-on program for N1MM Logger that displays contest multipliers on a map as they are worked. The program reads from the specified N1MM Logger database after each contact, provided that Mult Chaser and N1MM Logger are both configured appropriately.
Minimum System Requirements
- Windows XP Service Pack 3 or Later
- Microsoft Visual C++ 2010 Redistributable Package (x86)
- N1MM Logger or N1MM Logger+
The following instructions assume that N1MM Logger is already installed on your machine and that you have already prepared your contest in N1MM logger.
- Configure N1MM as outlined in the UDP Broadcasts Section
- Download the latest Mult Chaser ZIP and the desired Configuration ZIP file to your computer.
- Unzip the Mult Chaser ZIP file and the Configuration ZIP file to the directories of your choice.
- Open or run MultChaser.exe.
- On the File menu, click Open Configuration.
- Browse to the directory with the unzipped Configuration files, select the desired XML file, and choose Open.
- On the File menu, click Open Log from Other Database.
- Browse to the appropriate N1MM Logger database (MDB) file, select it, and choose Open.
- In the Select a Contest dialog, select the contest of interest, and choose Open.
- That's it. The program should be up and running.
Selecting the Configuration
Each time you re-start Mult Chaser, the latest configuration is automatically restored. To switch to a recently used configuration, point to Recent Configurations
on the File
menu, and click the desired file name. To switch to a configuration not available on the list, click Open Configuration
on the File
menu, browse to the desired XML file, and click Open
Selecting the Log
Each time you re-start Mult Chaser, the latest log is automatically re-loaded. To switch to a recently used log, point to Recent Logs
on the File
menu, and click the desired file name. To switch to a log not available on the list, click Open Log from Current Database
or Open Log from Other Database
on the File
menu, browse to the desired N1MM Logger MDB file, select it, and then select the desired contest log from the database. The name of your currently open database is used in place of Current Database in the first instance, and this allows bypassing of the database selection process.
N1MM Logger Run State
Mult Chaser does not require N1MM Logger to be open. Mult Chaser simply reads the specified N1MM Logger database. When N1MM Logger is open, Mult Chaser automatically re-scans the database as each QSO is made.
Mult Chaser configurations consist of two parts, a configuration file (XML) and a bitmap file (BMP). The bitmap file must be located in the same directory as the configuration file.
Mult Chaser allows the map display to be restricted to certain bands and modes through the Band
Keep on top
On the Tools
, menu click Keep on top
to prevent Mult Chaser from being hidden behind other programs such as N1MM Logger.
Limits on Automatic Scanning
As long as UDP broadcasts are enabled correctly, the map updates after each QSO. However, N1MM Logger does not send a message to add-on programs if contact information is edited or deleted. The easiest way to refresh the map in that case is to make another contact in the program. Another option is to re-select the current band or mode filter.
The Colors sub-menu under the Tools menu has options for changing the colors displayed on the map. The selected colors are saved for future use, but the default color scheme can be restored at any time by clicking Reset to Default Colors.
N1MM Logger sends data to external programs using UDP broadcasts. Some broadcasts contain information about the mode and frequencies of each radio. Other broadcasts indicate that a new contact has been logged.
Mult Chaser uses contact broadcasts and plans are in place for it to use radio broadcasts. Each contact broadcast is used to trigger a new scan of the contest log in the open database, which in turn is used to update the map. In future versions, radio broadcasts may be used in order to have the band and mode filter automatically track the selected radio
The N1MM logger.ini file must be updated to enable UDP broadcasts. The ini file must contain an [ExternalBroadcast] section. The following example of the [ExternalBroadcast] section is recommended.
The destination port defaults to 12060 in Mult Chaser. This value can be changed by clicking UDP Port... on the Tools menu. The new port setting takes effect immediately.
