@KN6FVK Hey John,
I just looked at your account and you have 3 logbooks. Two pota and one regular logbook. It doesn’t look like either of those 3 are a contest logbook though so exporting to a Cabrillo wouldn’t work right as there is no exchange fields to pull from.
When participating in a contest you’ll need to goto the contest page (World Radio League) and then select the contest you want to enroll in and either click the ‘Join for free’ button on the main contest list page (link above) or go into a specific contest and click the ‘enroll now’ or ‘join for free’ buttons. This will create a contest logbook with the correct exchange fields. Then once your done you can export to a Cabrillo file.
I hope this makes sense.
Thanks & 73
