[Harp-L] Question for position guys

[David Payne <dave@xxxxxxxxxxxxxxxxxxxxxx>]

I've never been much on positions, although I can figure out 1st, 2nd, 4th and 5th easy enough. Like one a short while back at the Huntington Harmonica club, they called a song in F minor and I wound up playing a D chromatic with the button pushed in the entire time, so that would have been transforming the chromatic to an Eb chromatic and playing 5th position on it. 
But to get that, I was thinking about chords, thinking that if I pushed the button it, I'd have an F minor chord, then I could play in F minor. Now, after I started playing it, I figured out that was 5th position I was doing. 
So, I came across a recording of me back when I was still in school. The song was Em. I was playing an A harmonica.  

What position is that?
