MDARC has updated our D-STAR repeater to new equipment.? We are using a controller called Multi Mode Digital Voice Modem (MMDVM) and have initially enabled D-STAR, DMR and C4FM/YSF. Here are some details.

The repeater, when idle, will listen for all enabled modes.? When it hears an inbound transmission, it will repeat that transmission and temporarily expect the response transmission to be in the same mode.? So if a D-STAR user calls out and someone responds (could be local, could be on a linked reflector), the repeater will listen up to 20 seconds just for D-STAR.? If the QSO ends and there is no response, then after 20 seconds, the repeater will go back to listening for D-STAR, DMR and C4FM/YSF.?

In the above scenario, if a DMR user calls out and gets into a QSO, then the same process will happen.

Our hope is that no one DV mode will "take over" the W6CX DV repeater, but at the same time, users of all three modes will have fun using this wide-coverage repeater.? We will work with our members to ensure users of all enabled modes have a fair shot at using the repeater.

Online Forums

MDARC has created a new Digital Voice forum called W6CX-DigitalVoice. We want to move current w6cx-dstar forum activity to this new forum.? Current subscribers will soon receive an invitation to join the new forum.? Others can ask to join at /g/W6CX-DigitalVoice/join .

D-STAR

For D-STAR, users are free to issue linking commands from their radios to link to any REF, XRF, DCS or XLX reflector they wish.?

DMR

Our DMR system will be connected to the BrandMeister network. There will be one static talkgroup (Diablo 310606) on Timeslot 1 -- this TG is meant for users in the Mount Diablo region.? Users will, of course, be able to dynamically activate BrandMeister talkgroups of their choice.? PLEASE USE TIMESLOT 2 FOR DYNAMIC TGs.? Dynamic TGs will drop after 10 minutes of? local RF inactivity.

C4FM

Our C4FM/YSF/Fusion mode is linked to YSF80280 - US-Contra-Costa - Wires-X80280.?

Tip: Listen AND check your radio before calling out

There are many other MMDVM multi-mode repeaters operating in the world.? A well-known one is K6PUW in Southern California.? On Oat Mountain overlooking much of the Los Angeles basin, this repeater has 4 DV modes enabled, and users of all 4 modes have learned how to use it.? Key is that before calling out, they first check their radio to make sure the repeater is not busy.? All radios have a display showing if a signal is being received.? If we see the repeater is transmitting but we don't hear anything on our radio, then we'll know another mode is using the repeater right now.? K6PUW users just wait a while, check their radio and when the repeater is no longer busy, they call out with their favorite mode and radio.

What’s Next

If you are new to the DV modes, we'll be happy to work with you to get going with whatever of our 3 modes you have chosen.? If you are a long-time DV user and have a suggested improvement to how the W6CX DV repeater should be managed or configured, please let us know.

We'll be posting more info in upcoming notes.? Our goal is to allow our users to really enjoy these Digital Voice modes.

I'm trying to update my settings which I could do just two weeks ago at?. This website appears to be down. Where do we go now to do this as I was registered in D-Star with this gateway? If I try to log on here, it says my callsign/password is not valid.?

Ken,

Regarding callsign registration page -- Sorry about that.? I am writing a post that will explain what’s going on, but basically our D-STAR callsign registration page is down and will be for about 3 weeks.

During that time, if someone registered at W6CX needs to add or change terminals on their callsign registration account, I will need to ask the Trust Server Team to remove them from the W6CX connection and the person can then re-register at another gateway, for example, the REGIST gateway.

I see from that you currently have 2 terminals – the standard one with a space in the initial or module letter, and another with a Z.? I suspect the latter has the AccessPoint box checked.

What kind of new terminal or changes to your current terminals do you need to make?? I will be happy to help you re-register so you can proceed with the changes if that’s what you’d like to do.

If you could remove me that would be great and I can re-register. Thanks Jim. Just email me when that is complete or post here.

Larry,

Thanks very much for collecting those posts (and formatting them!) into one document.? It makes a nice overview of the digital voice project.
