As promised, I checked for the emergence of the 1181 signal on SpecLab last night
Here is the plot: http://paulc.mediumwaveradio.org/images/11814.jpg Times are BST (deduct 1 hour for UTC). The random yellow dots show that no signal is being received. The first evidence of a signal is at around 2250 UTC and the signal is established at 2305 UTC. The emergence of the signal is consistent with the previous nights observations This map shows the greyline at 2300 UTC: http://paulc.mediumwaveradio.org/images/sunset.jpg Sunset is just reaching Santo Domingo in the Dominican Republic at this time. I note that the two directional plots on Glenn's chart http://tonnesoftware.com/1180B.gif point rather more towards the Dominican Republic than they do towards Cuba.
