The aurora of 17th March 2015, St Patrick’s Day, was a superb event: It was good enough to propagate signals on 50MHz across the Atlantic<\/a>, which I found particularly interesting. Unfortunately I haven’t had much time to get anything in the blog about conditions on 144MHz, so here’s an effort to get at least something recorded!<\/p>\n

The QSO map for 2m looked like this:<\/p>\n

\""St<\/a>

EI3KD (IO51vw) QSO map for 144MHz during aurora on 17th March, 2015<\/p><\/div>\n

<\/p>\n

The map shows a wide coverage from fairly well north into Sweden (SK0EN, JO99jx\/1884km)<\/strong>, all the way down to Croatia (9A1CAL, JN86dm\/1867km)<\/strong>, with the best distance being to the east, with\u00a0SP4MPB (KO03HT\/1932km)<\/strong> and SP4K (KO03HS\/1933km)<\/strong>.<\/p>\n

Signals were generally quite strong, as demonstrated by a few audio clips:<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t

Chris, SP4K, was a little weak in QSB during our QSO, but I heard him several times before and after at much better strength. At one point I was listening to SP4MPB\u00a0working 9A1CAL and could hear both stations! I only started the recording at the end of my QSO with 9A1CAL (i.e. at around 16:50z) but have at least a couple of hours of audio after then, so might add some more clips as I find time – please leave\u00a0a comment if you have a special request.<\/p>\n

Finally, the full 2m log is here, which can be sorted by time, distance, etc, if you have javascript enabled:<\/p>\n
