[WriteLog] split feature request

[Wayne, W5XD]

/It would be handy to put some simple control like %S in the exchange message, that will set SPLIT before
transmitting./

Limited way. (But I have another, more complete, solution below...)
This can be done with recent versions of WriteLog using the $GTnnn, but 
with a limited set of rigs: K2, K3, Kenwood, FTDX-9000,5000,2000. The 
reason for the limitation is that WriteLog only supports sending custom 
commands to those rigs that have ASCII characters on their COM port 
protocol.

It takes some head scratching to figure out what "$GTnnn" means and how 
to put that in WriteLog's F-key memory setup, and you also have to make 
some writelog.ini entries in [Elecraft_K3_commands] or [Yaesu_commands], 
etc. Use the WriteLog Manual entry in Windows Start menu, find the 
"Search" tab and search for "commands" and look for the [xyz_Commands] 
and also for Tools Keyboard Shortcuts

Way you can try today.
Another alternative that also could be made to work with recent versions 
of WriteLog, and that would work with any rig that WriteLog already 
supports (including the FT-1000MP you mention) is to write a custom 
keyboard processor. See the documentation at:
     http://writelog.com/ExternalShortcuts/

In fact, what you are requesting is really a beginner's programming 
project. And I think its ideal for such a project because its use is so 
specialized that I don't see a good reason to provide and support this 
feature for all WriteLog users. So I could not help but demonstrate that 
fact, and have placed the following zip file on writelog.com:
     http://writelog.com/Downloads/WriteLogSplitCommands.zip
The honest truth is that writing the code in that download took me less 
time than composing the rest of this email, which is instructions on how 
to install it.

Instructions:
Download the above zip file.
Unzip it into a temporary location.
You will get a number of files when you unzip, but I have included all 
the sources such that the free version of Microsoft Visual Studio can 
build it from source. But I have also included a built version of it, so 
all you need to do to try this out is follow the install instructions at 
the bottom of http://writelog.com/ExternalShortcuts/, which I customize 
here:

1. From the unzipped temporary location, find the file 
bin\Release\WriteLogSplitCommands.dll

2. Copy that file into your WriteLog install directory \Programs. You 
specified this when you installed WriteLog, but by default it would be:  
C:\Program Files (x86)\WriteLog\Programs on a x64 version of Windows, 
and without the "(x86)" bit if you have 32 bit windows. Just find the 
right directory and copy WriteLogSplitCommands.dll into it. If you have 
the default Windows User Access Control turned on (and I recommend you 
do! but that is another topic) it will ask for admin privileges to make 
the copy.

3. Edit writelog.ini. Find the [configuration] section and add these two 
lines:
ExtShortcutAssembly=WriteLogSplitCommands
ExtShortcutClass=WriteLogSplitCommands.ShortcutProcessor

4. The next time you bring up WriteLog, have a look at Setup keyboard 
Shortcuts. It will have these new entries under "Commands to run":
Use this one to have the keyboard processor save your current split 
configuration. It remembers your TX frequency.
     External: Save TX freq

Use these 10 to send F-key message Message01 through Message10. But with 
the special behavior that before sending the message, the keyboard 
processor sets the rig to split, and to the TX frequency you saved using 
"Save TX freq".
     External: Split Message 1
     External: Split Message 2
     ...and so on, through Split Message 10.

With all the above, then, you do the Save TX freq just once on a run 
frequency.
Click in the bandmap.
Then hit the F-key as programmed for "External Split Message n". And you 
get the behavior you requested.
