Thank you Steve, I found it and meant to post a link. I got side tracked working on dmrlink.

DMRgateway
by Robert Newberry 23 Jan '16

23 Jan '16

Is there any updates on progress of DMRgateway. Last I knew it was one way. I'm not complaining, I just got my DV3000 and I hope to start working on that this weekend. I have my repeater all ready to go up on the hill. I got my connections mostly secured to DMR-MARC and I got the contact information for brandmiester in the US. Looking forward to turning things loose. Apparently me applying for a repeater ID, has started the rumor mill and my intentions has created some buzz. There is a local digital group up here with a c bridge that is the only game in town. They are mostly focused on emergency communications. I will be focused on fun and technical conversation. Hopefully once this is up and running MMDVM will be next. N1XBM Apparare Scientor Paratus Communicare Allstar Node # 27086, 41540, 41812, 42086, 42658

Saw this online today. It's a complete reverse engineering of the radio, and it may be of interest to some of us. http://hackaday.com/2016/01/19/shmoocon-2016-reverse-engineering-cheap-chin… 73's -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net

Ambe_audio.py
by Robert Newberry 19 Jan '16

19 Jan '16

So I've been looking at the files. I'm hoping that I can designate locally a TG ID that will go out over my ASL network and of coarse in the opposite direction and traffic on ASL will work that ID on my DMR repeater. From looking at this files is the tg_filter in Ambe_audio.py where I would designate this? I guess where I'm confused is I get when I'm connected to Steve's test master how to map the IDd from his network to mine. How do I map a TG ID just for my ASL node? thank you N1XBM Apparare Scientor Paratus Communicare Allstar Node # 27086, 41540, 41812, 42086, 42658

DV3000 arrived
by Robert Newberry 19 Jan '16

19 Jan '16

So I have a few logistical questions. I currently run dmrlink on a installation of DIAL that I plan on being the same node that I want to use with DMRgateway. I think if I understand things right I can bundle dmrlink, DMRgateway, DV3000, ASL node all right on the same RPI2 right at my xpr8300. My thought was having my connections to other IPSC networks and then establishing a TG ID for my ASL node. So I guess I'd expect the email list to pick up with lots of questions. How is the software coming to allow two way communication? N1XBM Apparare Scientor Paratus Communicare Allstar Node # 27086, 41540, 41812, 42086, 42658

MMDVM and Home Brew Repeater
by Steve Zingman 19 Jan '16

19 Jan '16

The current version of MMDVM modem firmware and the MMDVMHost program are functioning well as a Home Brew DMR Repeater. I'm using a pair of Tait T20xx mobiles, the receiver connected to the discriminator and the transmitter connected to the TCXO audio board. The modem is a Arduino Due with the prototype audio board. The MMDVMHost program is running on a Raspberry PI2. I'm using the Raspberry Pi2 version of DIAL. It's Debian Jessie. (it just works) CPU utilization is very low. Audio is good, little or no dropouts. MMDVMHost provides network connectivity to BrandMeister, So I'm able to carry on QSO with remote users. Since ASL 2100 is connected to BrandMeister, My audio is being repeateted out on ASL. I do plan to try out other RF equipment, including Motorola, Kenwood and a Tait T800 repeater. 73, Steve N4IRS -- "Anything is possible if you don't know what you are talking about." 1st Law of Logic

MMDVM limited DMR success
by Steve Zingman 17 Jan '16

17 Jan '16

I had my first QSO using the MMDVM on DMR. Using a pair of Tait 20XX mobile radios and the MMDVM. Current firmware and MMDVMHost software running a Raspberry Pi2. Installed and compiled from the G4KLX repository on github. 73, Steve N4IRS -- "Anything is possible if you don't know what you are talking about." 1st Law of Logic

MMDVM Lessons learned so far.
by Steve Zingman 10 Jan '16

Mike and I have been working with the MMDVM and the Home Brew Repeater code for a couple of weeks. It's very early in the process and I think that unless you like to try to hit at least 3 moving targets, I suggest people wait. 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.
