Which onboard equipment is used to receive NDB signals?

A CDI is commonly associated with course guidance such as VOR, while a transponder responds to SSR interrogations. **Key takeaway:** NDB reception requires an ADF.\n\n**Glossary:** **NDB**: non-directional beacon; **ADF**: automatic direction finder.
