Operator notes
• Built as a practical operating plan for 23–28 April 2026 from Kosovo.
• Treat 20 m as the primary band. Watch 17 m and 15 m closely during daylight.
• Use 10 m / 12 m as opportunistic bands. Check 30 m / 40 m especially after sunset.
• Adjust daily using live Kp, A-index, F10.7, and blackout alerts.
