30 days, unless UTC reports a nearby power line carrier system.

  1. After 24 hours
  2. After 90 days
  3. After 30 days, unless UTC flags a nearby PLC system ✔

Why: Rule 97.303(g) requires notifying the Utilities Telecom Council (now the Utilities Technology Council). You may start after 30 days unless UTC says you are within 1 km of a power line carrier system.

Huh, didn't know that: Stations on 2200 m and 630 m may operate only from fixed locations, at least 1 km horizontally from power lines carrying PLC signals on those bands.
