     @ftg @mossmann i've actually used osmocom-analog on NMT450 before, in a cheeky "nobody will notice if i do this for 20 minutes" way!

     i don't think i can use the 450 MHz band in the UK any more than i can use the 800 MHz band sadly. but yes i like how non-fussy osmocom-analog is, and the code is very readable too. excellent work by, i think, @LaF0rge?

     @whitequark @ftg @mossmann I was not involved in osmocom-analog. It's entirely the work of Andreas "jolly" Eversberg. And yes, it's amazing work. I've had the pleasure of witnessing it from it's very humble brginnings.

     @whitequark cstone did AMPS in GNU Radio a while back https://github.com/unsynchronized/gr-amps

     @mossmann @whitequark
     And now there is also osmocom-analog, so the network side can also be done. With as little or as much SDR as desired.
     http://osmocom-analog.eversberg.eu/

     It also supports the 450MHz NMT450 and MPT1327, so no need to try to find a quiet spot on 900MHz either.

     @ftg @whitequark @mossmann jolly is sadly not on mastodon, not that I know of. His next amazing project is to operate a Siemens #EWSD Digital telephone exchange at #38c3 interconnected with @eventphone powering @c3isdn

     @whitequark @mossmann @LaF0rge
     I think it was by Jolly (sadly don't know their mastodon handle, if they have one). Excellent work in any case.
