Thanks for the report Colin. I've noticed a similar frequency shift on the last few passes also. Not sure of the cause though.
As a side note, I've actually found that it's easier to clean up recorded audio files with Audacity if the CW audio frequency is higher than what I feel comfortable listening to. It just seems easier to filter out the noise and then change the pitch if need be.
