Hi Roy - It doesn't appear that there are numeric range checks. In fact there's no requirement that the fields are numbers.
You can actually log a value such as 5NN or None - it does not matter. You just cannot leave the CALL, SENT, or RECV fields blank.
The EXCH and NR fields can be left blank, or you can log the other op's name and state abbreviation or section abbreviation (for example) if you wanted.
