I've put a bounty on this protocol support. It's more common than POCSAG in the US as well, as far as I can see. What I'd like to see from the bounty is the abilty to receive and decode FLEX like multimon-ng ideally for both 2FSK (1600/3200 bps) and 4FSK (3200/6400 bps). I don't know of any available FLEX transmitting software so for testing one would need to be in an area with FLEX signals, but if not it might be possible to collect some sampled signals off the air for replay via sdr.

Hi!

I'm in possession of pager testing equipment that's capable of transmitting FLEX. I don't own any FLEX receivers however I'll be willing to help in the near future. :3

Moved from #474
Volleyoghurt commented 23 minutes ago •
In the Netherlands we use Flex (P2000) for emergency services.
Is it possible to add this feature to the mayhem software.

The decoding of the software is already been done for Linux.
https://github.com/EliasOenal/multimon-ng

More information about the protocol.

http://jelmerbruijn.nl/motorola-flex-p2000-decoding/
Frequency is 169,650 MHz
I don't have the knowledge to convert it to the mayhem software.

The best possible solution is the have a RX and a TX option.

Thanks!

As mentioned in #483. https://github.com/craigshelley/multimon-ng/blob/master/demod_flex.c might be a good start.
