Thanks for the explanation John. I am a little puzzled why Mark 
wanted to update every few seconds for something used to display 3 
sec dot QRSS or slower where it takes several minutes for the trace 
to disappear off the screen.... Your 5 minute update seems far more 
sensible. And you are right, doing it from a server at home on ADSL 
brings the ADSL upload speed into the equation as well, something 
many people forget. Remember that 512kbits/s (NOT Mbits...) 
corresponds to only 40kBYTES/s and that is dead slow for large 
files....

I see now that Mark has reduced his file size and display size which 
has largely solved the issue. But I am puzzled when he said the old 
file was 600kB, what I downloaded was most certainly 1.2Mb!!

Sorry to hear about your antennas John, hope you soon sort it out. I 
worked MM0XAU on 40m on your island yesterday and he didn't mention 
storms, only lousy HF conditions..
