Narrative:
Passing 2000 ft MSL after takeoff when we got a clean intermittent configuration warning horn. Recycled gear and flaps without success. Lowered flaps to 1 degree to silence horn. Ran configuration checklist without success. Called dispatch to put call through to maintenance. Was overweight for landing back at our departure airport. I was in and out of icing conditions after takeoff with temperature less than 10 degrees centigrade and in visible moisture. Since flaps were out and a limitation exists with holding in icing conditions with flaps deployed is prohibited; I continued on course to our filed destination to get out of icing conditions. Also; I had the IAS disagree light on. This was a repeat write-up. Could not correct either malfunction so an emergency was declared and I diverted to an enroute airport. Made an uneventful overweight landing at 151;300 pounds.
