MeshCom is a great project for off-grid messaging using low-cost and low-power-consuming hardware. The platform used LORA to be able to build a mesh.
Have a look at the setup I build and how this all works. Thanks to great team building and maintaning this!
From a good friend I was given a Rohde & Schwarz SMDU which needed some love and care.
Martin, DL8RI, did a phenominal job in documenting his SMDU repair work on this website:
I followed a lot of the work he did. In my SMDU the two main problems were a faulty power supply and the famous power switch that didnt work anymore.

Please check out this great documentary on HAM radio produced by students from the School of Visual and Media Arts program at the University of Montana in 2022. Aired on Montana PBS on November 24th, 2022.
I always like the MD-9600 as a radio but disliked the firmware. Therefor I got really excited that I read that OpenGD77 got ported to this radio. I started with a v2 hardware radio and installed the Alpha version that got released early march. Without any expectations (as it was an alpha version firmware) I was very very impressed.
I was so impressed I searched for a v5 firmware radio which I got a couple of weeks ago (after long long searching). Not having had much time I got to unpack the radio for installation of the OpenGD77 firmware.
To my surprise I learned last night the first beta-build was available already. It took me 20 minutes or so to install the firmware and load the OpenGD77 codeplug and contact list.
All information on the OpenGD77 firmware for the MD9600 can be found here:

Someone made a very nice overview on the mapping of keypad controls (OpenGD77-MD9600).
Overall I’m really excited about this firmware – I love the OpenGD77 codeplug editor, and now the MD9600 is a true HAM Radio DMR radio. I use it in my shack as a fixed station radio only.

After a long period of alignment and working on the non-US 501(c)(3) equivalency determination, DARC is now finally non-US 501(c)(3) equivalent and able to receive grants from the ARDC Foundation.
Please have a look at the press release here:
after I installed 2 Diamond X5000 antennas on my roof and I played a bit with my 23cm transverter from SG-Lab ( http://www.sg-lab.com/TR1300/tr1300.html ) I wanted a dedicated 23cm FM transceiver. On E-bay there was no real offering and the Kenwood (tm741) I got from a friend unfortunately died (controller) before I could even test it ;-).
So I found the 23cm NBFM TRX project from Bas PE1JPD from Holland:
This is a really nice kit for a very good price ( €157 )and I decided to order it. Very well packaged I received the kit very quickly and Bas even added an additional PCB which takes the display, mic connector and all other switches and buttons (for mounting behind the front display) – this saves wiring.
So today (01.06.2019) I got both the receiver and transmitter working correctly and I tested succesfully on a couple of 23cm relais in the region. So the following is open:
