GAC and HRPT at the same time #13

I have a recording sampled at 10MSPS with HRPT and GAC being transmitted at the same time. image How would I be able to split the two into separate WAV files for demodulation? I assume GNURadio is my friend here, but whenever I try it it spits out garbage. I tried to high pass filter the GAC and low pass the HRPT, but for whatever reason, it does not work.

Any ideas as to how to demod it?

Thank you very much for your time! :)

I just realized I didn't attach the recording. Here is a less-than-one-second recording (I couldn't fit anything longer). baseband.zip

I tried this flowgraph I made (terrible to say the least). It seems to filter HRPT alright, but GAC is terrible. Also, for whatever reason, HRPT is attenuated :( image

That looks like it should work, I will have a better look when I get home from work.
