I know that a while back there was a grc flowraph of op25 that handled DES. Any chance of a pybombs recipe for op25 that handles RC4 as implemented in Advanced Digital Privacy?

Migration of op25.osmocom.org ?
by Harald Welte laforge＠gnumonks.org [op25-dev] 10 Jan '17

Dear all, the op25.osmocom.org site is currently a lxc (linxu container) setup on one of my servers, and it frequently locks up the entire container every so often, without any reason why. I have failed to find the root cause of this and given up by now. As all of the other osmocom projects have meanwhile migrated away from trac to the redmine based setup at http://projects.osmocom.org/, I would stongly suggest the OP25 project to migrate there, too. This would include: * migration of the wiki pages (Holger has some semi-automatic process for that which imports the content but still requires manual fix-up of a lot of formatting) * migration of the tickets (Holger also did that programmatically for the other projects) * import of the SVN repository to our git server (see http://git.osmocom.org) Is there a way we can encourage the current active OP25 community to go ahead with the above migration? In the end, the closer you align in terms of infrastructure with the other osmocom.org projects, the more likely it is that the content will be available, systems and software updated, content backed up, etc. I think in the end, it would be better for everyone - including me for being responsible that the site is currently down very often.

APCO P25 Decoding error (aUaUaU...) [5 Attachments]
by pindrop82＠yahoo.com [op25-dev] 14 Nov '16

Greetings, Was able to install (Ubuntu 14.04) and have a working APCO P25 receiver, but when i run scope.py to decode the primary CC i am getting aUaUaU....error (see attached terminal error). It only works partially (audio interrupted or broken) when i omit the secondary CC (866.0750) from the trunk.tsv file. The problem may be the secondary control channel in the trunk.tsv file. When I add the secondary CC on the trunk.tsv it does not go to primary channel. P25 receiver attempts to decode on the alternate CC. Have not been able to fix that issue. I am using the same NAC for both CC! Command Line: ./scope.py --args 'rtl=0' -N 'LNA:40' -S 960000 -f 868.06250 -o 20000 -q 44 -v 0 -V -T trunk.tsv Attached trunk.tsv, talkgroups.tsv, terminal error, traffic screenshot and constellation screenhot. Any help would be appreciated. Best Regards, TJ
