My apologies for raising ancient history (I've done this to you before) and I note the earlier "rolling code" issue.

Have you ever looked at using simpler receivers typically tuned to 433.9 MHz (i.e. the centre of the ISM band) and intended for OOK modulation? If so, is it your experience that these have a reasonable chance of at least detecting that data has been sent at some frequency within the band?

This is just a "thought experiment" (i.e. feel free to jump in if it interests you) but I was wondering whether it would be possible to have a suitable wideband RF frontend feeding a signal to e.g. a Tang Nano FPGA configured to implement USARTs of various speeds and frame formats in parallel.

I asked about the RF side on SE earlier, the one useful response I got before it was ruled inadmissible due to being a "request for product recommendation" was that a single receiver probably wouldn't be able to cover the entire band.
