How sync works
First run — On startup with an empty database, a full sync downloads the complete FCC amateur radio dump (~200 MB, ~750K records). Takes 2–4 minutes.
Daily delta — Every night at 3:00 AM UTC, the server downloads that day's FCC delta file (changes only — typically a few hundred records). Takes seconds.
Manual full sync — Use "Run Full Sync" if the server was offline for multiple days (daily deltas are overwritten weekly by FCC). Takes 2–4 minutes.
Manual delta sync — Use "Run Delta Sync" to pull today's latest changes on demand.

Add Call Sign to Blocklist
Blocked call signs display a respectful privacy notice instead of their FCC details. The FCC data is still publicly available at fcc.gov — this only hides it on this site.
