What makes the scanner receive better? Min or Max squelch?

Well Minimum squelch helps you receive DISTANT transmissions better. That's really the only use for minimum squelch. Maximum squelch will block out transmissions that are either distant, or even nearby. With MAX squelch set, a signal needs to be VERY close to your scanner or the scanner won't pick it up. As a rule of thumb, turn squelch to the point just after the hissing noise stops.

A better antenna.......


I would think that your scanner is more "sensitive" when you minimize the squelch. I always set mine at the threshold, just before it creates static. The more you open it up, you block weaker signals. But I am no expert.

It depends how you define the terms ('min/max squelch' and 'better'.

Yes, I'm serious.

If by better you mean the most transmissions, that means one way. If by better you mean with the least noise on received transmissions, that means the opposite.

Minimum and maximum squelch are not firmly defined terms. To some, maximum squelch means the point just before the squelch opens. To others, maximum squelch is the setting which requires the strongest signal to open the squelch (the setting opposite open squelch).

Most people set the squelch just above the open squelch threshold in order to receive as many transmissions as possible, although some will have considerable noise on them.

If you only want to receive signals with little or no noise on them, set the squelch as far from the open squelch as possible.

Open squelch is the point at which you hear noise with no signal present on an open channel (one not using CTCSS or CDCSS).
