Thank you, appreciate it.

I apologise for saying no airports, it is apparent from the log that some must have got some but not any of the ones I checked.

I re-installed Plan-G 3.2.2 today and rebuilt the database from X-Plane 11.  After doing this there are no communications frequencies associated with airports.

I tried going back to 3.2.1 and rebuilding but had the same issue.  See below extract from log.
