1. Unable to perform station searches using the L & R buttons (remote & front panel).

2. Impossible to disable AF. The AF display symbol reflects the menu selection but AF is still always active.

3. AF changes frequency to 98.0MHz every few minutes. This appears to happen while tuned to BBCR1 (99.1MHz) and BBCR4 (93.9MHz), I haven't observed this behaviour on independent stations.

I mostly listen to radio in the middle of the south-central area shown here - see the light blue 99.1MHz patch. With BBCR1 for example, it always switches from 99.1MHz to 98.0MHz within a few minutes. Meanwhile, the AF debug display permanently displays the "WAIT" screen. Changing the preset station away and back again corrects it for anything up to 2 minutes, rinse and repeat.

I cannot 100% confirm this but I think that in areas of weak reception, the 98.0MHz switching tends not to happen.
