Do you have equipment to test all that? a flex pager? You could open a bounty on this, send a pager to somebody who wants to work on your bounty. Otherwise is very unlikely that somebody would work on this.

RX would be nice given the P2000 system in the Netherlands runs on this, I can read the message via

rtl_fm -f 169.65M -M fm -s 22050 -p 83 -g 30 | multimon-ng -a FLEX -t raw /dev/stdin

fierytechknowhows commented 3 years ago

I have an rtl-sdr with sdrsharp software to recieve the signal and pdw pager decoding software to decode the flex pager signal.

epvuc commented 3 years ago

Flex receive (and sure, TX also) would be pretty great, as it's getting to be much more prevalent than POCSAG. multimon-ng can decode Flex as well as POCSAG with no problem, so it's probably not terribly different.

Flex TX is pain compared to POCSAG. Constant broadcasting and slots have to be in the correct place and you can only send a page 1 per four minutes to a pager iirc
