How do you properly set your squelch?

This is both a question I get asked all the time, and sometimes not enough!


What you need to know

The squelch is the threshold for the amount of signal required to trigger the scanner into receiving a signal.  

Setting the signal too low will allow any signal level to come into your scanner.   This is useful for weak signal listening or DX operations. Many operators using HF will keep their squelch open.

Setting the squelch too high will block all but the strongest signals from coming into your scanner.

Make sure you set your squelch on a frequency setup for CSQ or Carrier Squelch.   Do not adjust your squelch on a frequency that is setup to require CTCSS or DCS, or that is digital.

Turn the squelch down until you hear the white noise on the frequency and then dial it back to the point where the radio was quiet.   This is the minimum setting required to keep your sanity and your radio quiet 🙂
