Note: the WriteLog.ini file is no longer used in Version 12 – all of the options are in dialog boxes, not in this file. I’m keeping it on the site because there are older installations of WriteLog and those use this file.

You should upgrade to the current version!

This page, in no particular order, reflects the major WriteLog INI settings for ham radios. The bracketed words (e.g., [Configuration]) reflects which section of the INI file the entry should be made or be found.

General [Rigs]

The COMn:= settings in [RIGS], as of version 10.41, are used for ham radio control (only)—but just to control the baud rate and number of stop bits. WriteLog always sets no parity and 8 bit characters for ham radio control, regardless of the COMn: settings.


ICOM [Rigs]

ICOM Split Frequency

Setting this entry to 1 causes the WriteLog Icom driver to send a split on/off command to the ham radio every time it polls the rig for its frequency. This means that WriteLog is sure to know whether the rig is set for split.


Setting this option to 2 causes WriteLog to do the same as setting to 1, but, in addition, if you tune the rig from its front panel more than 500Hz after WriteLog has set it to split, then WriteLog automatically turns the split off.


Note: WriteLog versions 10.30 and older behave like option (2) above for all non-zero settings of this option.

ICOM Rig Addresses [Rigs]

The following entries override WriteLog’s default setting for the ICOM rig address for the various ICOM rigs. All rigs that have ICOM rig addresses have corresponding entries in WriteLog.ini here under the name that matches the name in the Setup Ports dialog including space characters!

Icom IC-781=0x33
Icom IC-756PRO=0x12

Kachina [Rigs]

For WriteLog to talk to the Kachina front panel software, it must know where the Kachina software is installed.


The nn is the number of the COM port the Kachina is connected to, as the Kachina software calls for a different directory for each radio.

Orion [Rigs]

WriteLog by default sets the Orion RIT to 0 Hz on an RIT clear command. However, the rig also disables RIT in response. If you set OrionRITClearHz to a small number, the RIT will remain on.
