Hi Wolf

One issue noted that may be worth exploring.

For fast waterfall display speeds like listening to VLF natural noise, 
the waterfall speed seems forced to one rate only for any setting I give 
it, whether with the FFT settings or waterfall scroll interval...

And apparently related is the contrast and brightness controls seem to 
do strange things to data already in the buffer when adjusted...

Hope this helps.
