  1. 14.070 MHz
  2. 14.200 MHz
  3. 14.100 MHz ✔

Why: The ARRL band plan lists 14.100 MHz for NCDXF beacons on 20 m. Hams listen there to gauge how well the band is open without calling anyone.

Huh, didn't know that: The 20 m packet segments in the ARRL plan match the HF segments where FCC rule 97.221(b) allows automatic data control.
