Squelch Settings

I've noticed that when I put the radio into scan mode the scanning will stop on channels at random, I keep turning up the squelch for the radio and have SQL tight checked for the channels. It seems like I have to make the squelch much higher if I make it a scanning radio instead of just monitoring one channel. Does anyone else have to do this as well?
The model is F121S
The squelch is set at 240 and the sql tight offset is 255 and the radio still gets hung up on channels where there is no traffic.

hmm I checked my CS-F100 file in Set Mode and mine is set at 75

I have noticed with another Icom, it would lock up on a channel in scan mode until I touched the monitor button briefly, and then it would resume scanning.

I have to have mine set to 220, but I don't have ctcss tones turned on. Do you?

Reverse Burst Timer 0.300

RX AF Filter NORMAL

User CTCSS freq 88.5 not sure why, it that the default?

Some of my radios have "hysteresis" type squelch and they tend to have the same behavior.
I think this is common with radios that use H squelch.

ah ha, that makes sense.
I'll have to do some testing to see what the impact of my higher squelch setting is.
Hopefully the h squelch will adjust
