Propagation prediction for NL6/AA7CH NA-157, Kayak Island, Grid BO79qt
Below is propagation forecast for all 40 zones. Special thanks to Jari Perkiömäki, OH6BG/OG6G for VOACAP software. The forecast is based on average Solar Spot Number, SpiderBeam antenna for 20 and 17 m and Verticals for 30-80 m on TX side. 3 el. Yagi @20 m and dipoles for 30-80 m were used at RX side for modeling.
The forecast is slightly different from that for NA-042. Kayak Island is located 120 km (75 miles) southeast from Hinchinbrook Island.
You can have your own propagation prediction entering your Grid Locator to the window on the right. The outcome will be a bunch of charts which might be somewhat difficult to read. You should look at blue REL line, when it is above red dash-and-dot line, then you should tune on your radio and turn antenna to Alaska.
Real propagation and, therefore, possibility to make QSO can be quite different from the pictures. Ionosphere in high latitudes is very dependant on aurora, so with solar index K=2 and above European paths can be very challenging. With K>4 there might be total blackout with no propagation on any band to any direction. However, strong Aurora might cause some openings on 10 and 12 m.
Local noise level, antennas used and output power on receive side will definitely affect on signal-to-noise ratio on both ends of the QSO path. Red dash-and-dot line on the chart represents quiet conditions on RX side.
