I think it sounds wrong because the letter “U” is pronounced “yew”, and y is not a vowel. You would never say ‘an yurt’ or ‘an yogurt’. If it was prounced “oo”, then “an oo F O” would sound correct.
But as it is, it just sounds wrong. And whether technically correct or not, I reject it!
Auto up vote for using “an” correctly.

But, a down vote for misspelling.
