How to read the charts

The chart shows the best frequency to use if working from the UK to each area. The dark green (squares) plot shows the optimum frequency and the light green plot shows the next best frequency to use. The dark green blob plot shows the reliability of the path as a percentage that it is likely to be open.These are based on CW, 100W, dipole to dipole and a "fair" reception. Adjust the reliability according to your own station.

Newfoundland

Reliability/Band graph produced by WinCap Wizard/VOACAP
This shows that to work the Newfoundland-based stations from within the UK, 40m (7 MHz)
is probably your best bet after dark and in the early morning/evening
20m (14 MHz) is a possibility from about 1100 UTC until1800 UTC.
Note the possible 10MHz openings early evening- I have never heard IMD
stations on 30m myself.
