Re: [IRCA] 1181 viewed from Scotland

[Paul Crankshaw <paulc@xxxxxxxxxxx>]

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:

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.
