Thoughts on VoIP to DV3000
by Matthew Pitts 07 Nov '15

07 Nov '15

All right guys, Here are some of my thoughts on this: 1) We will need the DV3000 to get D-STAR AMBE into the system. 2) We should be able to get DMR audio into it without needing an external AMBE chip; however, it may require an addition to the repeater programming software that isn't standard to activate the capabilities. 3) Wires-X is an unknown at this point, though I suspect we can accommodate it somehow.

DCI
by Robert Newberry 05 Nov '15

05 Nov '15

So I've been looking at DMR networks. I am across EWARN which appears tied into DCI. They have all kinds of links going on all of the different formats. Even a allstar node. Anyone know anything about this and how they're doing it? N1XBM Apparare Scientor Paratus Communicare Allstar Node # 27086, 41540, 41812, 42086

If you're not seeing it then I must have it wrong. I'm trying hard but I think I'll get egg on my face. Page three says the gateway uses ulaw audio format to transfer linear digital audio to the repeater. The dstar channel driver uses ulaw audio in digital frames too. I believe you'll need a dongle of sorts. I feel like I'm stepping in some deep shit. Allstar network wasn't even in my vocabulary two years ago.

DMR-DSTAR bridge
by Robert Newberry 04 Nov '15

04 Nov '15

Has anyone successfully used the hytera repeater to feed the data stream into the dstar channel driver on allstar. There is a document on it on the ham-dmr.de website. Wondering what your thoughts are on how it sounds? We have a friend who is an over the road truck driver. He uses his DV dongle to connect to a xrf reflector to connect to us on analog and it sounds fine both ways. Looks like a good way to get DMR on allstar. One time slot for allstar and the second for what ever talkgroup you wish. N1XBM Apparare Scientor Paratus Communicare Allstar Node # 27086, 41540, 41812, 42086

Thanks to Mike N4IRR being impatient, I received my DV4Mini today. I have it running on a Odroid C1 under Jessie. The UI is running on my Linux work station. Played a little with D-Star on the DCS006 Z. Seems to work. Have not had a real QSO yet. Played around a little with DMR+ More to follow.

USRP

Just to get things started. The USRP channel driver is a very useful tool for getting PCM audio in/our of allstar in a pure digital format. We used this to transfer decoded AMBE from DMR to Allstar with this snipit of code: *#define USRP_PCM_SAMPLES **160* * #define USRP_VOICE_FRAME_SIZE (USRP_PCM_SAMPLES*sizeof(short)) // 0.02 * 8k* * #define USRP_ENDPOINT "192.168.1.180"* * #define USRP_PORT 32001* * enum { USRP_TYPE_VOICE=0, USRP_TYPE_DTMF, USRP_TYPE_TEXT };* * // udp data header* * struct _chan_usrp_bufhdr {* * char eye[4]; // verification string* * uint32_t seq; // sequence counter* * uint32_t memory; // memory ID or zero (default)* * uint32_t keyup; // tracks PTT state* * uint32_t talkgroup; // trunk TG id* * uint32_t type; // see above enum* * uint32_t mpxid; // for future use* * uint32_t reserved; // for future use* * short audio[USRP_PCM_SAMPLES];* * };* * static DV3000_UDP *udp2 = NULL;* * static int seq = 0;* * void sendAudioToUSRP( void *buffer, int bytes )* * {* * struct _chan_usrp_bufhdr packet;* * unsigned char *recvBuffer = (unsigned char *)&packet;* * int packetSize = sizeof( struct _chan_usrp_bufhdr );* * memset(recvBuffer, 0, packetSize);* * if (udp2 == NULL)* * {* * char address[] = USRP_ENDPOINT;* * udp2 = new DV3000_UDP();* * udp2->openSocket(address, USRP_PORT);* * if (packetSize != ((USRP_PCM_SAMPLES * sizeof(short)) + (8 * sizeof(uint32_t))))* * printf("Alignment error");* * }* * memcpy(packet.eye, "USRP", 4);* * packet.keyup = 1;* * packet.seq = htonl(seq++);* * packet.type = USRP_TYPE_VOICE;* * memcpy(packet.audio, buffer, bytes);* * udp2->writeSocket(recvBuffer, packetSize);* * }*

Welcome to AllStar Digital
by Steve N4IRS 30 Oct '15

30 Oct '15

Welcome to AllStar Digital. I wanted to move the discussions of Digital modes built on AllStar off the regular list and on to a place we can discuss without bothering the analog only people. At least for now, anything goes. I do not want to move or replace the normal list yet another list. Standard AllStar questions should still be on the app_rpt users list. -- ,,, (o o) -----ooO-(_)-Ooo------ --- N4IRS was Here ---
