My Empeg won't change station-frequencies. I got it once then never again (driving daily between two of these stations). The Signal is first best then becomes lower and lower until two (and a half) bars are remaining. Then I only hear noise (so there shouln't be any bars left). I can switch manually to the other frequency and the signal is strong. When I switch to the old frequency where no more signal is present it won't switch back. AF is on.
I heard of a "hack" to watch what's written into the AF-Variable. Is it gone since the latest hijack? Or do I have to press some secret buttons first?
