Two national simplex references and official band-plan links.
What Are the National 2 Meter and 70 Centimeter Simplex Calling Frequencies?
U.S. national analog FM simplex calling references for Technician and higher classes. Use the same transmit and receive frequency; check local guidance and listen first.
| Band | Frequency | Mode / Operation |
|---|---|---|
| 2 m · VHF | 146.520 MHz | FM · Simplex |
| 70 cm · UHF | 446.000 MHz | FM · Simplex |
Calling frequencies are a place to establish contact; consider moving a longer conversation to an appropriate clear simplex channel.
A band plan describes recommended uses. Your license privileges and FCC rules determine what you may transmit. A broad “all modes” label is not permission to use every mode anywhere in a band.
