I'm sorry I didn't get a chance to look at this last night. I'll take a look tonight after work.
I'd like to remind everybody that there is a write-up on how to create recipes in the documentation folder of CabConverter. At first glance, I think the problem with this one is in the QSO portion where we're using an unknown tag. It should have been something like STX or SRX for the sent text and received text fields.
Also, if you run CabConverter from the command line it will show error messages for what when wrong during the recipe's parsing.
More tonight. 73!
