When i then turn the big VFO knob, the frequeny and zoom center stands still and the spektrum and waterfall moves in the direction i turn the knob.
When i zoom out as far as possible with the Z-, then the spektrum and waterfall stands still and the zoom center and frequency moves to the direction i turn on the knob. When i reach the screen border then the spektrum and waterfall starts moving too, which is ok.
As soon i zoom in a bit with Z+, the frequeny and zoom center stands still again and the spektrum and waterfall moves again.
to be honest, wouldn't it be a lot easier to tune to a station with the vfo wheel, that isn't just broadcasting, if you could use the trail on the stationary waterfall ??
that would massively improve its usefulness or not ?
please consider this usefull function in your next update.
