Nobody any ideas? If not, does anybody have some idea what the
difference between position 1+2, pos 3 and pos 4 could be? I was
thinking 1 and 2 might be working because of toneburst, but I don't
think Kaffeine uses such a signal and that doesn't explain why pos 3
works if first tuning to 1 or 2 and 4 doesn't work at all.
