Good information! I've seen WX0V's vids on YouTube on the 7610, nicely done vids. The 7610, although a superior scope to the 7600, still has the same issue for me. The firmware won't allow you to heighten the "blips" vertically. Such a short screen area prevents you from seeing weak signals. The P3 has a much taller screen area and can. I'm hoping the K4 will be able to too.
