Wow. I wonder if the chirpy signals are an artifact of the
receiver. I do remember hearing a lot of chirpy and hummy signals
from fishing boats on the HF marine bands. Its interesting that
all of this is at a pretty constant speed, maybe 20WPM or a bit
more. I can spot some bugs in there but I suspect most were hand
keys.
