  1. Checks incoming signal deviation
  2. Prevents interference to nearby repeaters
  3. Tunes through frequencies to check for activity ✔

Why: Scanning steps through a range of frequencies and stops when it finds a signal. It is a quick way to find out where people are talking.

Huh, didn't know that: Many radios can also scan only the memory channels you have saved.

My radio scans for activity all day. It's basically a teenager with a phone.
