Sorry, Graham, but you are wrong. Last night's results did not "give 
a good working compromise between real and false detections." There 
were several very plausible but false decodes. These appeared much 
more frequently than they do on OPDS which in any case gives enough 
additional information on signal quality to be able to spot most 
false decodes. It's a nice idea, but the real/false threshold is set 
much too far towards 'real', making the resultant information next to 
useless. 

And what is the "200%" fade figure all about? I am 1000% sure I don't 
know.
