Good first video.
Re the memories (in the program.) Could the VFO-B frequency be placed under VFO-A's in those memory panels?
In the video, the A frequency was showing as overlaying the B frequency when you created a new memory entry. Not visually good I think.
Tuning. Is the only control via the text fields at the top to the right of the graphic? Or, is there another way, I tried hovering the mouse over the tuning knob in the image and using the scroll wheel, but nothing happened.
I am aware of other tools, some allow the use of a mouse scroll wheel, either over the image of the tuning knob, or when hovering over a digit in the image display. (Fldigi/Flrig like.)
Overall, I'm impressed with what you've created, and would love to help (however I can) to move this forward for all.
PS: I'll do some more tests tonight, and see if I can get you an image of the issue with the netbook and small screen.
