On my Garmin Etrex Legend CX sometimes there are little "D"'s on the bars on the satellite page.
What do these mean? Do they have something to do with WAAS?

Yep. It indicates that the satellites are receiving WAAS corrections and these corrections are being sent to your GPS. If you disable WAAS on your GPS you won't see the D's. They may hang around for a couple of minutes but they'll disappear eventually.

By the way, the 'd' stands for "differential." This means you received a timing differential update on that specific satellite. The GPSRs typically only receive this update through a signal sent from the WAAS satellites. WAAS Satellites are any satellite you are receiving with a number of 33 or higher
