The MMDVM is a Arduino Due and a small analog board. The modem firmware runs on the Due. The analog board does some filtering and level control. We are running a early prototype board from Jim KI6ZUM. Jim has some new boards in the works, so right now waiting or build your own is the only choice. >>>> >>>> The software is early and buggy, as any new software is. Jonathan G4KLX has done a phenomenal job so far and it only will get better. The test software ONLY works in duplex mode, which is a problem because if your transmit data is not right, you will not get too far with receive. Kind of a catch 22. Jonathan G4KLX says that the deviation should be 3.88 KHz. So on my IFR 1200S that works out to a hair under 4KHz. (analog meter). Now that we have the transmit working OK, not great but OK, we will start on receiver. >>>> >>>> More to follow. >>>> >>>> For INAD, Steve N4IRS >>>> -- >>>> "Anything is possible if you don't know what you are talking about." >>>> 1st Law of Logic >>>> _______________________________________________ >>>> Allstar-Digital mailing list >>>> Allstar-Digital(a)lists.keekles.org >>>> http://lists.keekles.org/cgi-bin/mailman/listinfo/allstar-digital >>> _______________________________________________ >>> Allstar-Digital mailing list >>> Allstar-Digital(a)lists.keekles.org >>> http://lists.keekles.org/cgi-bin/mailman/listinfo/allstar-digital > _______________________________________________ > Allstar-Digital mailing list > Allstar-Digital(a)lists.keekles.org > http://lists.keekles.org/cgi-bin/mailman/listinfo/allstar-digital _______________________________________________ Allstar-Digital mailing list Allstar-Digital(a)lists.keekles.org http://lists.keekles.org/cgi-bin/mailman/listinfo/allstar-digital

MMDVM and DMRlink

Merry Christmas We are working on 2 modules for DMRlink. 1: Support for "HomeBrew Repeater" as defined by DL5DI, G4KLX, DG1HT <https://bm.pd0zry.nl/images/5/54/DMRplus_IPSC_Protocol_for_HB_repeater.pdf> 2: Support for the DV4Mini How many people have or plan to add a MMDVM to their toy box? -- "Anything is possible if you don't know what you are talking about." 1st Law of Logic

DMRgateway
by Robert Newberry 28 Dec '15

28 Dec '15

I was poking around in the files that were installed when I loaded everything on the RPI2. I was specifically looking for documentation on DMRgateway. I saw a PDF that did a pretty good explanation. I was got a rough idea from looking at ambe_audio and DMRgateway.ini. Is there any interest from the group on a round table about DMRgateway? Preferably after the New year holiday?

Bridge errors (lessons learned)
by Robert Newberry 28 Dec '15

28 Dec '15

I wanted to detail some woes I was having with getting my bridge running with the "test master" in FL. (stand by for old buzzard transmission) First off let me explain my setup for the benefit of others. I have a XPR8300 at my house on low power and dummy loads. I am using a HT programmed for that local repeater and the talkgroups I want to monitor. I then setup dmrlink.cfg with two entries one for Steve's master in FL which I called N4IRS_PEER since I am peered to him. I then setup a second entry N1XBM_MASTER since all of my repeater equipment will peer to that as my master. I then configured bridge_rules.py for two entries N4IRS_PEER and N1XBM_MASTER this have to be entered exactly as they are in dmrlink.cfg or things will not work! I then added the talkgroups I wanted to monitor for each entry. Think of this like Mable's switch board from the old timey days. Example DMR-MARC North America is talkgroup 3, time slot 1. So under N4IRS_PEER SRC_TS': 1, 'SRC_GROUP': 3, 'DST_NET': 'N1XBM_MASTER', 'DST_TS': 1, ' DST_GROUP': 3}, Under N1XBM_MASTER SRC_TS': 1, 'SRC_GROUP': 3, 'DST_NET': 'N4IRS_PEER', 'DST_TS': 1, 'DST_GROUP ': 3}, This sends it in both directions. So mistake number 1 I highlighted N4IRS_PEER in red because I accidently called it N4IRS_MASTER. I was getting this error when I would try to TX. File "bridge.py", line 163, in group_voice _status = networks[_target].IPSC_STATUS # Shorthand to reduce length and make it easier to read exceptions.KeyError: 'N4IRS_MASTER' That was my clue, what ever you designate in dmrlink.cfg must exactly match in bridge_rules.py. Mistake number 2 was a really tricky one and I had help to figure this out. When I was testing playback, it just wasn't playing back. There were no errors being generated, which made it extremely tough to troubleshoot. When setting up the repeater I put the channel as mixed mode just to play with the analog side to. Even though it shouldn't work my repeater was registering with my master. It wasn't until I said maybe I should change this to straight digital channel, that playback started working. The last thing was purely a misunderstanding on my part. I misunderstood Steve, and thought I was going to be able to hear myself on ASL 2100. I was banging my head against the wall not understanding why it wasn't working. How ever if someone from this group was on at the same time as me on the same TS/TG we could talk to ourselves. I hope this helps anyone coming after me attempting to do this. Now I gotta order a DV3000! Bob/N1XBM

bridge one way audio
by Robert Newberry 27 Dec '15

27 Dec '15

So I started this morning working on getting things setup so that I can peer to the test master in FL and be able to listen to myself on 2100. So in my /opt/dmrlink/bridge I edited it to have the information Steve provided for the test master. I also setup up a master to point my repeater to. I setup my bridge rules for TG 1 and TG 3 just to keep it simple until I understand things. I hear people when they come up on North America, but my audio isnt heard on ASL 2100. I also put in my bridge rules the test master with both TGs and their destination to my master I also reversed this on my master entry pointing everything back to the test master. I get this error when I TX. Unhandled Error Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/twisted/python/log.py", line 73, in callWithContext return context.call({ILogContext: newCtx}, func, *args, **kw) File "/usr/lib/python2.7/dist-packages/twisted/python/context.py", line 118, in callWithContext return self.currentContext().callWithContext(ctx, func, *args, **kw) File "/usr/lib/python2.7/dist-packages/twisted/python/context.py", line 81, in callWithContext return func(*args,**kw) File "/usr/lib/python2.7/dist-packages/twisted/internet/posixbase.py", line 614, in _doReadOrWrite why = selectable.doRead() --- <exception caught here> --- File "/usr/lib/python2.7/dist-packages/twisted/internet/udp.py", line 246, in doRead self.protocol.datagramReceived(data, addr) File "/opt/dmrlink/bridge/dmrlink.py", line 1171, in datagramReceived self.group_voice(self._network, _src_sub, _dst_sub, _ts, _end, _peerid, data) File "bridge.py", line 163, in group_voice _status = networks[_target].IPSC_STATUS # Shorthand to reduce length and make it easier to read exceptions.KeyError: 'N4IRS_MASTER'

Playback success
by Robert Newberry 26 Dec '15

26 Dec '15

So I finally got playback working. Kinda got lead into thinking I was on the right path. I set my repeater for mixed mode thinking I could use analog in my initial testing phase, obviously not for IPSC, just dub stuff around the house. Anyways it actually registered like it was working, but it would never playback. I had asked for help and found out, that mixed mode will not work. May seem like a no brainer but it caught me. SO MAKE SURE YOUR REPEATER HAS A DIGITAL ONLY CHANNEL. Anyways now I need to bridge the rest of my talkgroups and test on ASL 2100, then I'm buying a dv3000. Thank you to everyone on the list that responded to my help request. N1XBM Apparare Scientor Paratus Communicare Allstar Node # 27086, 41540, 41812, 42086, 42658

So in dmrlink.cfg I have my RPI2 as a master. I've pointed my repeater at my RPI2. That all seems fine, where I'm confused is how does the software know how or where to echo the audio back to?

Round table

Family commitments prevented me from listening to all of the round table. I like the idea since we're all hams and communicating over the radio is what we do. I love to participate in another if it happens again. N1XBM Apparare Scientor Paratus Communicare Allstar Node # 27086, 41540, 41812, 42086, 42658
