Good day to all,
I will be trying out a few operating system images with the Raspberry Pi 3 in the next few days.
The first custom made image I will try out is the one by KB5RAB, which has a bunch of amateur software pre-installed on it, including the MD-380 Tools package.
Here is the link to get the image, a 16 gig SD card is required for imaging it properly:
Filename is: KB5RAB_8gb_YSF_pixel_031817.zip
Here below are the release notes for this version of the image, along with everything that is included.
The Image supports DMR, DSTAR and Fusion and each mode can be enabled as desired.

Motorola MTR2000 UHF Repeater Dstar Project
Wanted to let all of you know that soon The VE2RMP Radio Group will have a new D-star repeater on 448.625- to replace the MSF-5000 Motorola D-star repeater.
The MTR2000 is a much improved unit and is a everything in one package repeater. Before I go any further I have to say a big thank you to Claude VE2YI our president for supplying the repeater.
Well I brought the repeater home and installed the programming software on an old dell P4 running windows XP. I made up my own programming cable using a db -9 connector at one end and a RJ-45 at the other. It only uses 3 Wires and is very easy to get the information on the internet. I then of course used a USB to serial adaptor as it is very hard to find computers today with a serial port unless it has been added.
Once this was done you take off the front plate of the repeater to expose the MIC-RSS plugs.
This where the programming cables goes.
a lot of information on the internet and some I just used common sense as I have been around Claude for quite some time helping him at the repeater sites so there many things you pick up without realizing it.
Once this is done the only thing left is to take an old mouse cable with the 6 pin din plug on one end and wire it up to the dvptr-1 board.
Pin 1 = Output Audio from the DVRPTR-1 Board
Pin 2 = Ground
Pin 3 = PTT
Pin 4 = input from the FM Demodulator ( Audio coming out of MRT2000)
Once you have indentified these wires then the MTR2000 has a 96 Pin plug in the back 3 rows of 32 . Each pin has a function and again all this information can be found on the internet. I then took stiff wire and soldered small pieces to the 4 wires in question and inserted them into the correct pins on the back.
The computer and software used is a small Beagle Bone Black running an image from Ramish VA3UV who offers his help and support whenever needed. The software work very well and allows for Identifier of the repeater and scheduling for automatically connecting to reflectors for nets at specific times.Here is a photo of the DVRPTR-1 Board and the Beagle Bone black Underneath.
The repeater at the moment is operating at my house as VE2YUU on 442.050 Plus for testing and Hopefully in the next 2 to 3 weeks will be placed up at Ridgewood as VA2RMP frequency 448.625 minus.
Here is the MTR2000 with the cover back and on the air. The repeater is linked to XRF005B so come on and test it I will be listening.
This has been a fun project and I want to thank Claude VE2YI for supplying the repeater and Ramish for all his support over the years when I have had questions and needed assistance.
Hopefully the next project will be with a MTR2000 and a MMDVM Board and a Raspberry PI-3 this will make a repeater that will do D-Star - Fusion (C4FM) - DMR and P25
Take Care and 73 from Cliff VE2YU
