  2. 146.94 MHz
  3. 146.55 MHz

Why: The ARRL 2 m band plan lists 146.52 MHz as the national simplex calling frequency. Hams monitor it and then move to another simplex frequency to talk.

Huh, didn't know that: The plan also lists 144.200 MHz as a separate National calling frequency, in the SSB part of the band.
