Greetings to all,
I just created a page for the RMP group to give the club more visibility on Facebook.
That page will have all the necessary contact information, plus a link to the RMP web site.
I also plan to upload some Field Day pictures and other information on it as time goes by.
Here is the link to the page:

KB5RAB system image for Raspberry Pi 3
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:
https://spaces.hightail.com/space/se06G/files
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.

Based off W1MSG Pi 3 Jessie Image. and includes the following:
Now includes PIXEL Desktop.
- MMDVMHost software by G4KLX https://github.com/g4klx/MMDVMHost
- ircDDBgateway (DStar Gateway software) https://github.com/dl5di/OpenDV/wik...
- MMDVMHost-Dashboard Web dashboard by DG9VH https://github.com/dg9vh/MMDVMHost-...
- MD380Tools Software for creating and loading MD380/390 custom firmware from KK4VCZ travisgoodspeed https://github.com/travisgoodspeed/...
- YSFGateway software by G4KLX https://github.com/g4klx/YSFClients...
- BlueDV Linux software by PA7LIM (Beta Version 09352 ) http://www.pa7lim.nl/bluedv-linux/
- Updated DV4mini software 3/2017 (works with latest 1.77 firmware) and DV4MF2 panel version 12
- Brandmeister XTG Dialer for Dv4Mini by K2DLS http://www.k2dls.net/blog/2017/01/1...
- Various desktop shortcuts for easy usage of key functions as well as readme files for documentation of features and operations. Shortcuts are now also included in a Ham Radio section added to the Pi menu. Readme file and a pdf with sample mmdvmhost.ini settings in zip file with image.
MMDVMHost runs as a service and is set to auto start. Bluetooth disabled to allow DVMEGA to work on Pi GPIO pins and internal WIFI to function on a Pi3 . All log files needed from MMDVMHost, ircDDBgateway and YSFGateway to allow the dashboard to function are written to RAM disk.
Image may be updated periodically to contain the latest versions of the added software. I will keep the current link to the image in this file on BM3148 Facebook group.

Motorola MTR2000 UHF Repeater Dstar Project
Hello Everyone
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.
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

Icom IC-7300 review
Icom IC-7300 is the first direct sampling SDR (software defined radio) available from one of the "big three" japanese manufacturers. This helps it bring a whole new level of performance at an accesible price point, a much more flexible configuration and a set of features only seen in top-of-the line equipment. Real-time panadapter or fully customizable filters are just the tip of the iceberg.
Sure, amateur equipment has been using for a long time various levels of digital signal processing (DSP), but usually this was done in the last part of the receive chain, where it mostly impacted audio quality and not receiver performance. Moving to a direct-sampling SDR architecture means the signal coming from the antenna is directly transposed to the digital domain and instead of all the previously familiar receiver stages (such as mixers, filters, demodulators etc) we are using mathematical formulas applied to the data stream. The advantage of this approach is it eliminates all problems related to real-world hardware receivers (noise, distorsion, losses, imperfections, limitations etc) and opens up a new world on how you can use or visualize RF signals. Goodbye unwanted mixing products, AGC non-linearity, IF chain IMD or filter blow-by. You want a 200Hz to 2250Hz SSB filter ? Just go into the menu, customize it to that value and see how that carrier at 2260Hz simply doesn't get trough; yes, filter width and shape is just a matter of settings, leaving it all to mathematics to carry it out. Basically, the only part that limits the receiver performance is the Analog-Digital Converter (ADC) that samples the RF signal, and those are already very good.
