Transmitting digital

This may seem like a dumb question but I've been reading the documentation Steve has been posting and then googling different things. I found some stuff about USRP and P25. Are we actually talking it might be possible to tap a discriminator for RX and then feed into a modulator for TX. Let's say for example MSF5000? Obviously using the DV3000 as in the middle. Things certainly seem to be getting more interesting. I'm going to lay hands on this 8300 and purchase as DV3000 to start testing.

DMR
by Robert Newberry 30 Nov '15

30 Nov '15

So I was reading thru the documentation for DMRlink. One thing I found interesting was not only with proper software I can feed this into the USRP channel driver. It also appears this can function as a very basic c bridge. Am I understanding this right? I could could have a handful of DMR repeaters on my own IPSC network and have TG to route traffic to for example Allstar or just route to DMR only in my network of repeaters. I have the repeater it looks like I need a RPI2 and a DV300 it appears everything else is software. N1XBM Apparare Scientor Paratus Communicare Allstar Node # 27086, 41540, 41812, 42086

Re: [Allstar Digital] Allstar-Digital Digest, Vol 2, Issue 25

OK, I realize that I'm a little late coming to the party here...but, is there a BOM (bill of materials) aside from a DMR repeater and a working allstar (been doing it for 6 years...so, I think I can spin up another node...) node? Reason I'm asking is that I've come into the ability to get onto a 500' tower that already has a 440 stick near the top. Now, I'll have to get a 5.8 gig link back to my central net access point (about 8 air miles...Ubnt equipment is your friend), but, also have a moto UHF DMR repeater sitting in a box ready to go, and my local coord body is going to hunt for a pair on narrowband spacing to assign to me. So, assuming I have the repeater (and amp), duplexer, Pi2B, net connection...I think I'll need some dongle (AMBE?) to do the transcoding, another channel driver for allstar...a legit node number (though, I don't see this ever showing up on DMR-MARC like my other machine in Fairless Hills); I only plan on using this as a DMR link into my existing allstar network...) Thinking that the Pi uses the DIAL release? Or is Compton's version workable? saw something about a different channel driver...so, that's on the list to acquire and gen into the system (haven't looked to see if it is part of the distro). Am I missing something? I'll offer to collect FAQ information and re-post as need be (I know what it's like cranking on code and then facing doing the dox...) if that would be a help. And if I'm off base, I'm ok with that and will go back to lurking... 73 all Bryan WB0YLE

DMRGateway repository
by Steve Zingman 27 Nov '15

27 Nov '15

We have started posting the code needed to create the IPSC to AllStar gateway. The 2 repositories that we will use are: DMRlink <https://github.com/N4IRS/DMRlink> This is forked from the original author Cort N0MJS so that we can track the changes needed. If you are going to create and maintain a gateway, you will need to learn and understand DMRlink. It's written in python and runs fine on a RPi. DMRlink is the connection to the IPSC network. The changes are in ambe_audio.py. It has been modified to send the frames out via UDP. There is a added configuration file and a updated subscriber ID .csv file One of the sample programs you want to look at is playback.py This is the code used to create the echo or parrot TG for listening to your own DMR audio. DMRGateway <https://github.com/N4IRS/DMRGateway> This is the code used to get the AMBE frames from DMRlink via UDP format them and send to the DV3000 via UDP. The returned PCM (analog) is sent via UDP to the asterisk USRP channel driver. The code will be posted as it's cleaned up and prepared for human consumption. ;) Our next step is to build the analog to DMR path. DMRlink provides all the pieces needed to do this. 73, Steve N4IRS and Mike N4IRR -- "Anything is possible if you don't know what you are talking about." 1st Law of Logic

DMRGateway BiDirectional
by Steve Zingman 25 Nov '15

Right now we have audio in one direction, from IPSC to AllStar. The program still needs some work to make it easier to use. There will be a configuration file to control what Talk Groups, Time Slices and destination IP to send the PCM data to. There is no modification needed to AllStar. We are using the the stock USRP channel driver available in AllStar. We have the code to send audio from AllStar to IPSC using the same driver. Once we complete initial testing, we will make it available for people to test. The big thing to start is KEEP IT OFF DMR-MARC. Test it on a private network or on you local talk group. We still have a LOT of work to do. Right now, this is a proof of concept. 73, Steve N4IRS and Mike N4IRR -- "Anything is possible if you don't know what you are talking about." 1st Law of Logic

With technology gleaned from: DMRlink (N0MJS) NW Digital Radio Digital Voice Systems, Inc. Jonathan Naylor (G4KLX) DSD (Anonymous) Google N4IRR and N4IRS (INAD) would like to announce the first in a series of digital <---> analog Gateways. As a proof of concept, Virtual Hub Node 2100 is hosting the DMR-MARC to Allstar Gateway. This is a receive only Gateway bridging DMR-MARC. DCI and DMR+ to AllStar. This proof of concept is using no Motorola software or hardware. This is running on a Raspberry Pi2 Later versions of the Gateway will allow 2 way communications with Digital networks. 73, Steve N4IRS and Mike N4IRR AllStar Digital Discussion at: <http://lists.keekles.org/cgi-bin/mailman/listinfo/allstar-digital> All welcome. -- "Anything is possible if you don't know what you are talking about." 1st Law of Logic

Sorry, there was a problem with a user repeater locking up the hub. We are back up. Steve -- "Anything is possible if you don't know what you are talking about." 1st Law of Logic
