Well you could say that. No SpecLab instances froze, or were harmed, during the decoding of the 8 Chr message in Northampton UK IO92ng16, full decode sent to TX HQ for confirmation.

Based on the last carrier S/N of Alex' last decode this could be the result: http://abelian.org/ebnaut/calc.php?sndb=15.87&snbws=0.000035&snmps=&code=16K21&sp=30&crc=16&nc=8&submit=Calculate
But some hours will fall into daylight, so it will be quite close to the limit again! :-)
