ZS4TX at dawn

Interesting to see how ZS4TX heard my 14MHz, 1W signal compared to the 0.2W sent by M0VIK/MM (he uses his 'MM' as a prefix, but I give it as a suffix, as it's meant to be).  The plot has adjusted M0VIK/MM's output to a 1W equivalent.

Despite being to the NE of me, and thus experiencing the day advance about 30 minutes ahead, I was heard by ZS4TX 30 minutes before M0VIK/MM this morning.  But I was quickly outstripped as the benefits of a boat on water, even when it's moored in a harbour, came into effect.  

Note how the difference at peak 'greyline' time was 6dB in favour of M0VIK/MM, whereas for the rest of the period, it becomes about 15dB in his favour.
