I cannot get the RDS-stuff to work.

I've tuned to the Danish P3 channel at 91.7 with all three RDS-funtions enabled (TA, AF etc).

When I get to Horsens, half way to my destination, the signal looses quality to around 2/3 of the bars indicated. At that time the P3 channel is available with full signal strength at 90.7 but no switchover takes place.

Upon arriving at my destination in Vejle, the 91.7 signal is around 1/3 and the 90.7 is still full signal. Still no switchover has taken place.

This has been consistent for 2-3 days.

Is that a know bug, or am I doing something wrong? (The channel IS stored in a preset)
