Why can't I hear fire tones?
by nokoa3116＠gmail.com [op25-dev] 21 Jun '18

21 Jun '18

Before a fire dispatch they have a few beeps, I don't think it's for paging, I think just attention. They also have a beep everyonce in awhile in the police channel during restricted traffic. I cannot hear those using OP25, interested to know how I might get that to work?

RTL-SDR and OP25 on Linux Mint 64-bit
by mpuppet＠yahoo.com [op25-dev] 19 May '18

19 May '18

Hello everyone, First of all: Thank you to the admins for granting me access to this group! :) I am a musician and IT professional living in southern California, but I have little experience with radio. I recently bought an RTL-SDR dongle (the silver one) and I successfully got it working on Win10 with HDSDR and DSDplus, so I can decode DSD and P25 phase I, mainly. I also have an installation of Linux Mint, 64-bit. I'm running everything on a gaming PC that I built, so it's got a lot of speed and RAM. Before I gained access to this group, I followed this PDF to setup the dongle on Linux Mint: https://ranous.files.wordpress.com/2018/02/rtl-sdr4linux_quickstartv2-18.pdf https://ranous.files.wordpress.com/2018/02/rtl-sdr4linux_quickstartv2-18.pdf I then managed to get OP25 installed. Once I gained access to this group and started to skim over the various tips and tutorials, I took a few days to decide what options I wanted to try: Raspi+OP25? Ubuntu 14.04 32-bit in a VM? Or stick with Linux Mint? I decided to try the Ubuntu 14.04 32-bit tutorial yesterday. I spent the entire day trying to get Ubuntu 32-bit installed in a VM before I realized it didn't like that I was trying to give it 16GB of RAM. 8GB did the trick. But after following the tutorial found here from 2017, OP25 generated a lot of errors and decided to put it down and go back to Mint for a while. Through the tutorials and RadioReference.com, I managed to find a local p25 control channel for the police. So I setup a trunk.tsv file and trunkk.tsv with the groups I wanted to listen to. As of this morning, I was able to run OP25 in a terminal window in Mint, tuned to 470.025, using rx.py. The command I am running is: python rx.py --args 'rtl' -g 65 -f 470.025e6 -N 'LNA:49' -2 -V -v 0 -S 1000000 -q 2 -T trunk.tsv The problem is, I'm not sure if it is working because: 1. I hear no audio (using an external sound module, alsamixer is working properly to route audio to this device) 2. When I run the script with the above command, my terminal window fills up with the error "tuning error +1200". The frequency displays in the lower left corner as 470.025000. Pretty sure I'm doing something wrong, lol. Any help would be greatly appreciated. Thanks, MP

PDF Request - TIA 102 AABC - Trunking Control Channel Messages
by rhodey orbits rhodey＠anhonesteffort.org [op25-dev] 12 May '18

12 May '18

Greets All, I've found references to the TIA 102 AABC standard all across the web and other P25 standards documents, but I've never been able to find a copy of this document itself. Could anyone on this list point me in the direction of a copy? I think it'd be great if these documents were all checked into OP25 source control or uploaded on the Wiki somewhere. I really appreciate any help, thanks! -- rhodey

Public archive / unrestricted op25-dev group?
by Harald Welte laforge＠gnumonks.org [op25-dev] 12 May '18

12 May '18

I'm just quoting an (anonymized) excrept from an IRC conversation I had: ==== 19:42 < fooo> Does anyone know Max who is the main contributor to OP25 project? We're trying to run OP25 on XTRX and with many forks it's a bit difficult to understand what works and what doesn't (not to mention the setup is completely non-trivial by itself) 19:45 < Baaaaaaar> i guess.. no one? wasn't that abandoned years ago? 19:46 < baaaaaz> just receiving? maybe it's easier to get it working with rtl-sdr first and then work from there 19:50 < fooo> Not really abandoned - last commit Apr 27, 2018 19:50 < fooo> "max" branch 19:50 < fooo> There are also several forks which were never merged... 19:51 < fooo> baaaaaz, It doesn't really matter rtl-sdr vs XTRX since it's GnuRadio. It's that most how-tos are completely outdated and are not compatible with the modern GNURadio... 19:52 < fooo> Ideally we'd like Tx too - I saw someone on YouTube showing Tx and OP25 has a repeater mode. But yes. at least Rx would be nice 19:53 < baaaaaz> I see 19:54 <@LaF0rge> fooo: just contact their mailing list? 19:54 <@LaF0rge> Baaaaaaar: it's less abandoned than DECT or TETRA 19:55 <@LaF0rge> fooo: op25-dev(a)yahoogroups.com 19:55 < fooo> LaF0rge, Ok, thanks. 19:56 < fooo> Just curios - does he has any page/blog/LinkedIn? I don't think I've ever seen him at OsmoDevCons? 19:57 <@LaF0rge> fooo: none of the OP25 guys has ever showed up in person at any event. I guess they were originally from AU, so quite a bit far? 19:57 < fooo> AU = Australia? 19:57 <@LaF0rge> fooo: yes 19:58 < fooo> I see 19:58 < fooo> Looking at the commit history it's pretty much only Max who is contributing 19:59 <@LaF0rge> but maybe I remember wrongly. In any case, you won't find any APCO25 in Europe [not that I know of] so the "classic Osmocom people" have limited use for playing with it 20:17 < fooo> Btw, https://groups.yahoo.com/neo/search?query=op25 returns empty result 20:25 < Baaaaaaar> like i said... dead 20:29 < fooo> I don't think the project is dead, they just don't know/want to run it as a real community project... 20:29 < fooo> I mean they probably just care about scratching their own itch. Which is not bad, it's just not community 20:30 <@LaF0rge> the op25-dev mailing list is active. I'm following it. Many posts in april, few in may 20:31 <@LaF0rge> op25-dev-subscribe(a)yahoogroups.com should work 20:33 <@LaF0rge> https://groups.yahoo.com/neo/groups/op25-dev ==== All the above are long-term Osmocom developers. So as you can see, it's easy to jump to wrong conclusions, if most development happens out of master, and if the yahoo group is restricted/hidden and not publicly archived :) I'm not saying the fault is with OP25. If people want to jump to quick conclusions without informing themselves properly, they have no right to complain. And of course it's the OP25 developers decision how to run their project and their communications mechanisms, but I couldn't help but wonder and raise the questions below: Is there any specific reason that the op25-dev yahoo group is * restricted (i.e. no public archive) * not listed in the yahoo group index (makes it hard to find) I would argue that it's a FOSS project, and information related to it should be public rather than hidden. I also have an archive of op25-dev at least from March 2012 onwards that I'd be willing to share. We could import it into the lists.osmocom.org mailman so would have a web-accessible archive that can be indexed by search machines, etc. You could of course also migrate to a list on lists.osmocom.org, but that is of course a separate question, and always causing lots of fall-out, with everyone having to update their filter rules, aliases, etc. - so maybe not such a good idea. Let me know what you think about any of the suggestions above. Do with them what you like, it's just a friendly comment from your friends involved in other Osmocom projects... And btw: If anyone ever wants to show up for OsmoDevCon, please do reach out, we'd be more than happy to learn about OP25 and the people behind it!

Christmas Announcements 2017
by ikj1234i＠yahoo.com [op25-dev] 06 Apr '18

ANNOUNCEMENTS =============== 1) New Web site Our new web site is now on the air! I'd like to thank Matt Ames for his efforts and hard work in reworking content to fit the new format. I'd also like to take this opportunity to thank our hosts at Osmocom, Harald and Holger, for kindly offering this free resource and home for the project. web site: http://op25.osmocom.org/ git repo: https://git.osmocom.org/op25 2) Recent additions and updates Several updates have recently been pushed and are in the 'max' branch of the repo. In addition to bug fixes in both transmitter and receiver applications and libraries, there are a couple of new features: * remote terminal: the curses terminal may now run in a separate process or on a separate machine from rx.py, with connectivity via UDP. * dstar transmitter configuration: the dstar specific config options for repeater 1/2, mycall, and urcall are now supported. 3) CPU usage reduction effort Except for the actual speech decoding process which remains unchanged, the channel tuning and demodulation logic has undergone some streamlining. The result should be a significant reduction in CPU usage in rx.py, especially during idle periods. It's possible some of these optimizations may be slightly too radical; it would be good to receive feedback from all users, but especially from those with- * crowded bands with close channel spacing * p25 phase 2/tdma talkgroups * "center frequency" set to zero in the trunking tsv file 4) New multiple rx app Released today (Dec. 25, 2017) is a sneak preview of a new receiver app, multi_rx.py. It should be considered alpha test grade. The highlights: * receives DMR/YSF/P25(P1) (DSTAR almost finished) * an arbitrary number of concurrently active SDR devices * arbitrary numbers of channels/frequencies For more information see the README file in the apps/ directory of the repo. All of these additions have been pushed to the 'max' branch of the repo. If you have a previous installation of OP25 you should change to the 'build' directory of that installation and do sudo make uninstall prior to pulling and building the new version.

Streaming audio from OP25/Raspberry Pi
by John Ackermann N8UR jra＠febo.com [op25-dev] 22 Mar '18

22 Mar '18

I just got my RPi scanner set up to stream audio to an Icecast server. Graham did all the hard work to figure out how, so he gets all the credit. But I did collect the information together in a blog posting here: http://blog.febo.com/wp/?p=307 I'm also going to update my plug-and-play image file to include this. It may take me a couple of days to get that ready. 73, John
