Propagation predictions for AL3/AA7CH  NA-042, Hinchinbrook Island, Grid BP60sl

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 for RX side modeling.

 

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.
