Back in February of 2021, I had a post up about the new 144 MHz on St
Helena Island in the South Atlantic. Now we have the first reception report!
On the 1st of March 2021, Charles ZS1CF in Cape Town heard the ZD7GWM
beacon on St Helena Island over a distance of approximately 3145 kms. The beacon operates on 144.475 MHz with 25 watts on CW into a vertical antenna.
The tropo prediction map above from Pascal, F5LEN shows path and it is
believed that the propagation mode was via a maritime duct just above the ocean.
This marine path from South Africa to St Helena is a relatively common occurrence and successful contacts have been made on 2m and 70cms in the
last few years. It is hoped that the new beacon will give a better picture
of just how often this 3000km+ path opens and encourage others to have a
listen as well.
As outlined in the original beacon post, there may be a possibility of a
144 MHz trans-Atlantic path to Brazil or via TEP to Europe.Link...1) Update
