Using Logic-Analyzer to reverse-engineer ISM-band ASK/OOK encoding, possible?
I did exactly that in a previous project, I didn't use the open logic analyzer but the bus pirate which uses the same software.

I used this to decode the protocol for another project that sniffed RKE data.

Hope this helps.
