Smart SDR tunes at random increments..?

I'm running a 6300 with Smart SDR 1.2.1. When sliding the slice around, it snap-tunes at completely wrong increments. I set the tuning step to say 100hz, and it tunes 14.185.1, 14.185.2, 14.185.4, 14.185.6, 14.185.9 ,14.186.1 . A setting of 10hz tunes at 160hz steps. 1 hz tunes at 167hz increments. Settings of 500hz and above tune normally. Note: OK, I see that if you are displaying LESS than 300khz on the panadapter, it tunes correctly. Is this normal? Bob-AB5N

Bob,
Great question. I think what you're noticing is that if you are zoomed way out on the Panadapter, each pixel may represent more than your Tune Step Size. In that case, you may skip points. This is completely normal and is necessary to keep the Slice aligned within the Panadapter. Otherwise the Slice would not track the mouse movement on a really wide Panadapter.
It is probably easier if you understand that while dragging a Slice around on screen, the first thing that happens when the mouse moves is to identify what frequency is represented given the movement of the mouse. Then we apply the Snap Tune function to this. This means that even if each pixel represents 3kHz, the Snap will put it on the nearest step to that frequency.
