Just been trying to narrow this down lately. I've looked at past threads that seemed to have ended abruptly and others that address maybe half the issue.
From what I gather now, tightening the squelch (increasing the number) is supposed to allow Close Call to focus on stronger signals and eliminate background noise.
Originally with the 536hp I had just kept the squelch on the same number as with my routine scanning. At #2. Close Call picked up a few signals, including a ham radio frequency. So I just figured I would keep it at 2. But after looking deeper into the subject, most of the advice is to tighten the squelch, if not max out the number....not leave it low.
So for clarification, I'd like to have a little insight on a couple issues.
Will keeping the squelch low (like I had at 2) actually weaken the ability for Close Call to pick up signals and activate/alert? Initially I figured I would keep it low and if it broke through with white noise or static then so be it, I would just click it off and continue on. I wanted to be safe than sorry. But after further research, this thought-process seems to be possibly inaccurate. Even though the opposite at first glance is counter-intuitive.
Will tightening the squelch (a high number or maxing it out) actually improve the Close Call function to activate a hit? Reasoning behind this idea is that the scanner isn't listening to a bunch of noise so when there is a spike it activates and alerts. With the squelch low (like at my prior 2) then spikes of activity might just blur into the background more and not activate a hit.
Are any of these thought processes accurate or incorrect? Can anyone add anything to this to put the end to any doubt?
