Thanks. It relies on existing building blocks though, like #MMDVM , #GNURadio and the #DMR trunking controller (DMRTC) which has been in development for more than two years.

Anyone else experiencing #RaspberryPi systems failing lately?

I have a handful of 3Bs and 3B+s that I've been using since they were new and within the past year or two, every one of them has seemingly died. They light up, but don't seem to boot. I've tried different SD cards and power supplies, but to no avail. The last one to go was my #mmdvm hotspot. 😕

Look mom, I made this.

The first release on printable for a MMDVM Dual HS enclosure that is meant to be used without a Raspberry Pi mounted to it but using via USB connection. That's how I do it - and mmdvmhost runs inside a container that I built on my Raspberry Pi next to the svxlink container for fm-funknetz. Nice.

Some bit and bobs I been working on this week, set up two new HS's, duplex HS for #DMR and simplex HS for #YSF #POCSAG

I am really happy with the quality of the boards and work very well out the box with Pi-Star.

#m17 has been removed from #mmdvm Project: https://groups.io/g/OpenDV/message/2311

Looks like MMDVM is dropping support for M17,

Saturday projects:

We now have a 2.55 watt output Full Duplex UHF Pi-Star (DMR) Hotspot driven by a "Broadband 1-930 MHz 2w eBay Amp"

Having to run a -10dB attenuator (since the mmdvm outputs 10mw) to not blow up the amp since it only needs 1mw to run it

Hopefully driving the amp with 13.8v won't hurt it too much because it's only meant to be driven with 12v 👀 ...(Just a little spicy given it's output power heh :blobcat_thisisfine: )

Going to have to take a walk later on and see what it's range is like now :blobcatcheer2:

Just noticed on "Stan" there is a new series coming out this month called "Nightsleeper" and in the trailer it shows a #RaspberryPi with a Duplex #MMDVM hat and they calling it a hacking device

Lazywebs: I'm looking for the current #MMDVM interface specification. I found a really old one (https://www.f5uii.net/wp-content/uploads/2016/08/MMDVM-Specification-20150922.pdf) but there have been a number of additions to the spec such as POCSAG and CW ID commands/modes. I can rummage through the MMDVMHost source to figure it out but I haven't touched C/C++ in a LONG time. I want to communicate directly with an MMDVM board. #hamradio #amateurradio

My MMDVM stack (mmdvmhost, dmrgateway, ircddbgateway) runs on a Raspberry 5 in container. It's ok to ask WHY WOULD YOU DO THAT?

In case you want to, too? Here are the containerfiles: https://codeberg.org/rhaen/container-mmdvm

Friends low-ish cost fullduplex "SDR #raspberrypi hat now properly receives #DMR

Now we just need to learn how to actually configure the #MMDVM side of things.
As it is not like an SDR of which there are less than 10pcs in existence is supported in #Pi-Star or #WPSD.
Not yet anyway.

we have #M17 on a Duplex #MMDVM, Pi Zero 2 W with #WPSD dashboard. Now to wait for my #Module17 board to arrive so can test all this out 😺

#hamradio #digital

Attention #FT70 owners:

This is your monthly reminder that, if you intend to use it for #PiStar / #MMDVM, you can just plug it in to power and take the battery out.

Your battery will thank you.

I have to forget and remember this at least once a month.

#HamRadio #hamr

Meanwhile, on the #hamradio side I bought a Yaesu FT-3D so now I need to get my #pistar #mmdvm duplex hotspots updated and on-tune again.

Es gibt ein neues MMDVM Board für Duplex Betrieb. Es arbeitet mit Keramikantennen auf dem Board.

#hamradio #amateurradio #mmdvm

Jonathan G4KLX war jedoch nicht dazu bereit, noch mehr seiner Freizeit kostenlos für das Projekt zu opfern.
Vor allem, da sehr viele Einzelpersonen aber auch Unternehmen sehr viel Geld mit dem Verkauf von MMDVM-Hardware verdienen, die seine kostenlose Firm- und Software verwenden.

Seit kurzem tut sich jedoch wieder etwas auf seiner Github-Seite.

I started up my MMDVM hotspot for the first time in ages to monitor some DMR talkgroups and look at those beautiful loss and error rate numbers!

#HamRadio #AmateurRadio #DMR #MMDVM #PiStar

Hey, #hamradio community. I have a problem with my #DMR hotspot. I’m trying to update the #MMDVM hat’s firmware to get on #M17, but I can’t because the flash chip is locked. No problem, jumper J1 and pull BOOT low.

Well, this isn’t the popular model. This came on a pre-assembled #NanoPi hotspot, it doesn’t have the same jumpers, and I can’t find any solid information about this hat besides several AliExpress listings. Plus, there’s a screen permanently attached to the top. Can anyone help?

This audio might sound a lot better than the last #M17 net on 17:00 UTC Fri. I checked in on.

The recording done by friend @jared on one the multimode networks @vk3jed maintains here in VK, so basically it my #Module17 hooked to Yaesu FT-7800 going to my #MMDVM mini repeater with M17 to multimode network to #DMR that @jared is using. Also when this filmed I not been awake long 😹

#hamradio #digital @m17_project

bit & bobs to continue the mini repeater builds out Pi Zero 2 W and #MMDVM boards with #W0CHP dashboard software

Just ordered another #mmdvm #hotspot should be here in a couple of day, I'll have this one setup for #C4FM #Yaesu #Fusion #hamRadio

When I started my digital journey years ago, I started with #dstar #Icom ID-91,later getting a ID-92, but it wasn't until I got a ID-51 & hot spot that it really made since to me.

I moved to #DMR a few years ago-Picked that up right away, and understood it quickly
I got a early Christmas present of a #FT5DR - Using it for #APRS now, but hopefully more soon

Well I had an interesting night trying to update the firmware in my #MMDVM #DUPLEX #hotspot V1.3 hardware from #Firmware V1.5.2 to V1.6.1, well lets say it not go to any good plan, some how I damaged one board to the point that the RF stage seems to be dead as it does not receive or send and it didn't accept the new firmware.

The other the same didn't accept the new firmware and the JP1 solder pad half it came away on the solder wick.

So neither took the 1.6.1 firmware 😿

My lunch box #MMDVM hat has had added 3.5" #Nextion enhanced display to the lid, also added a 24V fan for air circulation. The power to all this is via a 12V to 5V buck converter and the fan is connected to the 12V input to that, and the Pi and MMDVM Dual at is connected to the USB socket with short cable.

Also has room to have a battery bank to be add to it in the future if needed

#hamradio #digital #DMR #DMR2YSF

So nice the #Nextion Enhanced drivers are included with the #W0CHP PiStar Dash, so I have connected the display back to my #MMDVM hat attached to the lid of the lunch box

My Duplex #MMDVM on a #RPi3B+ setup, just waiting for #W0CHP PiStar Dash to do it thing so I can connect to it and configure it
