Testing with NOAA-19

I've got my software to the point where I can just click on a button and it will record (and perhaps decode) that pass. I have come to the conclusion that my Doppler corrector isn't good enough, so I'll have to re-engineer that. I don't support all the modes & modulations & baud rates that I need yet, but am working on it. Some, for example, APT I'm still having to do by hand. When the weather cools down, I'll start to design a much better Gnuradio backend which will allow me to construct & control flow graphs better than the GRC ones I'm currently employing. Anyway, to end on here's a pretty picture that I just decoded from NOAA-19 on my RTL-SDR dongle:
