Hmmmm that's strange - I wonder what's up with 62.5kHz?? Seriously - why would they use that frequency?

Thanks for the heads - up about Q7 and Q8!

I found a minor mistake on the board. Q7 and Q8 need to be rotated 180 degrees before inserting them. I had fixed that a long time ago, installed a new version of designspark, and forgot that I had the old bad copy of that footprint. Oh well.
