I have a question that might be silly don't know but I'm going to ask anyway. I have two banks set up in my 2096 with ONLY hits in my area with TONES so I have the squelch totally off when I listen to those two banks ONLY. I've noticed with the squelch all the way down it scans like very slow , I can turn it to about oh 11 o'clock and it scans normally or faster anyway , when I turn it all the way it's like lightning...question is why is that ? squelch controls speed ?
