15 messages from Madeira, including quite a few clustered in the 0443-0501 UTC period.
As an aside, I ran a special test with custom software designed to record 24 bit I/Q data, vs the usual 16 bit. I was curious whether or not that would improve reception. I ran that data through the decoder twice, the second time stripping off the lower 8 bits, returning it to 16 bit resolution. There was no significant difference to the decoding. There was some variation, a few more messages for some stations, and fewer for others, but overall there was no improvement. While I was hoping this would improve decoding, at least now I know that 16 bit resolution is indeed adequate.
