How grey-line propo can help out

I don’t normally have much luck in logging Radio New Zealand here. Sometimes it’s due to when I can listen, i.e. the wrong time of day, but other times when RNZ is on air I just can’t receive them. With transmitter power from Rangitaiki of only 100KW it’s probably hardly surprising. However, tonight I was in for a bit of luck and the help of grey-line propagation. As can be seen below from the logs, I received RNZ at 17-14 UTC (18-14 BST), so here the sun was just setting. However, in New Zealand, the sun at that time is just rising and so gave the perfect conditions for grey line propo. Radio propagation along the grey line is very efficient.  One major reason for this is that the D layer, which absorbs HF signals, disappears rapidly on the sunset side of the grey line, and it has not yet built upon the sunrise side. 

So along with RNZ, I managed to hear a few more mainly from S.E. Asia. A nice hours listening
