 ## Call History Files

+
+Place a check in the `Use Call History` box. Call history files are very specific to the contest you are working. Example files can be obtained from [n1mm's](https://n1mmwp.hamdocs.com/mmfiles/categories/callhistory/?) website. They have a searchbox so you can find the contest you are looking for. If you are feeling masocistic, you can craft your own. The general makeup of the file is a header defining the fields to be used, followed by by lines of comma separated data.
+
+An example file excerpt looks like:
+
+```text
+!!Order!!,Call,Name,State,UserText,
+#
+# 0-This is helping file, LOG what is sent.
+# 1-Last Edit,2024-08-18
+# 2-Send any corrections direct to [email protected]
+# 3-Updated from the log of Marsh/KA5M
+# 4-Thanks Bjorn SM7IUN for his help. 
+# 5-Thanks
+# NAQPCW 
+# NAQPRTTY 
+# NAQPSSB 
+# SPRINTCW 
+# SPRINTLADD 
+# SPRINTNS 
+# SPRINTRTTY 
+# SPRINTSSB
+AA0AC,DAVE,MN,Example UserText
+AA0AI,STEVE,IA,
+AA0AO,TOM,MN,
+AA0AW,DOUG,MN,
+AA0BA,,TN,
+AA0BR,,CO,
+AA0BW,,MO,
+```
+
+The first line is the field definition header. The lines starting with a `#` are comments. Some of the comments are other contests that this file also works with.
+This is followed by the actual data. If the matched call has `UserText` information, that user text is populated to the bottom left of the logging window.
+
+So if one were to go to `FILE -> LOAD CALL HISTORY FILE` and choose a downloaded call history file for NAQP and typed in the call AA0AC while operating in the NAQP, after pressing space, one would see:
+
+![Call History Example](https://github.com/mbridak/not1mm/raw/master/pic/call_history_example.png)
+
+Where the Name and State would auto-populate and the UserText info apprears in the bottom left.
