An Investigation of Propagation on the North Atlantic path by monitoring the Canadian Naval Station CFH
last updated on 2 january 2001

Introduction During the night of 18-19 december 2000 CFH was monitored and recorded by several radioamateurs in Europe. The results of this recordings are given here. Certain similarities but also significant differences in the signal-strength versus time pattern can be noticed at the different locations.
Since most measurement were relative, the date of all recordings were 'equalized' to an average value of -30dB_relative
At this moment only the graphs are given, I will leave it to the more qualified to give interpretations of these data
Just before midnight CFH was off air for about 20 minutes. This 'off time' gave me the opportunity to 'synchronize' the various data. The 'on' and 'off' moments give also a good impression of the SNR at the different recording stations.
