ClemsonJeep, didn't know you were in the DC area! DC101 does broadcast it's call letters on RDS, though it's rare to get it. Actually, the best in the area for seeing RDS is NPR, believe it or not. They usually have an add for their web site, or some such, but they do broadcast the time, which means you can actually get the time set properly on a Mk. 1. I don't remember if there are any other RDS stations in the area, what with the rather weak tuner of the Mk.1
Can't wait to see the wife's Mk. 2 tuner.
Any chance you want to get together to compare installs, etc., sometime?
