Deploy like a team
Local net days and times change — clubs skip holidays, nets move for events, repeaters go down for maintenance, and third-party listings (RepeaterBook, etc.) are sometimes wrong on time zone or day of week. Always confirm on-air or with the club before you rely on a schedule. See something outdated here? Submit an update.
Keep the moat fresh
Wrong tone, retired repeater, or net that moved? Operators use this list on nets and in property assessments — your correction helps the next station.
