Dv4Mini TFT Raspberry Pi2/3 Image

We have created an Raspberry PI Raspian SDcard image for the PI2 and 3 containing both the DV4Mini abd DV4Mini Compact software. This image will boot up only with a Waveshare LCD TFT screen as seen here:


It requires an 8GB or greater SD card. Will only work on the Raspberry PI3 and Pi2. Use 7Zip software to decompress and either Win32DiskImager to copy the bootable image to an SD card.

You can download the image from here: http://latinovoip.net/dv4mini/dv4mini_combined_LCD35TFT.7z

The original DV4Mini can be found here: http://dv4m.ham-dmr.ch/. Once you download, copy the image, and boot it up. don’t forget to expand the SD card. To do that:

Log in as  user pi/raspberry via SSH or in LXE terminal. At the prompt, type:

sudo  raspi-config

In the config, perform the following:
Expand the filesystem to fill the SD card
Set your locale, timezone, and keyboard for your location to en-US-UTF8 (this has already been done)

It will boot to the TFT screen, not the HDMI monitor. 

If you want to switch to an HDMI monitir, use the terminal or SSH to it, login as pi/raspberry, and do this:

cd LCD-show/


It will reboot and show on HDMI monitor. Do this to switch back to LCD:

cd LCD-show/




Allstar and IRLP Portable Nodes + Raspberry PI


KP4TR IRLP Node 8205

Getting ready for Dayton 2016, so I decided to build 2 portable nodes. One for IRLP, and another for Allstar to take on the road.

The IRLP version is my personal node 8205. It is difficult to build these because of the proprietary and closed environment IRLP operates under, so I may not build any more of these. This uses a Baofeng BF888S radio, which are easy to modify, and make excellent UHF portable nodes.


KP4TR Allstar Portable Node

The Allstar version is not only easier to build, but can be used immediately as a private node or Echolink, or tied into the public Allstarlink network. So I can easily build these using either the DMK Engineering URI FOB, which are wonderful interfaces, or the R.A.L.I interface built by Omar Reyes (K9MAR).

Both IRLP and Allstar version use a Raspberry PI computer. The IRLP is a Raspberri PI2, where the Allstar is a Raspberry PI3. At the time of this posting I had issues using IRLP with the RPI3, but hopefully this has been resolved.


Here’s a video of the IRLP node 8205 and the multicolor LED and synthesized audio.






AIRA Cloud



El AIRA Cloud ha sido creado para mejorar el servicio de conferencia de *AIRA* y Allstar KB9PTI.

En ves de correr desde conexiones residenciales de Internet, ahora la conferencia de Echolink *AIRA* y el servidor de Allstar KB9PTI (28679) esta corriendo en servidores comerciales corriendo “en la nube”. Esto nos da la habilidad de aceptar múltiples conexiones y un ancho de banda mas amplio sin tener problemas de conectividad.

Para conectarse a la conferencia de *AIRA*, se conecta a la conferencia *AIRA* o el numero 1458 usando Echolink en el Iphone, Androide, o desde su casa usando Echolink en Windows.


Para conectarse a KB9PTI Allstar (28679) puede usar su nodo de Allstar para conectarse. Si desean escucharnos via “streaming audio” pueden visitar Broadcastify en: http://www.broadcastify.com/listen/feed/18955


Gracias a Omar Reyes (K9MAR) , Jay Santiago (KP4EOP) , y Ramon Gonzalez (KP4TR) por implementar este servicio.


OpenVue AllStar Node -K9MAR

Nuevo nodo de Allstar fabricado por Omar K9MAR con un RALI Interface. El RALI interface lo pueden obtener aqui: http://latinovoip.net/interfaces-allstar-r-a-l-i-de-k9mar/

Este nodo es un Baofeng BF-888S, una Raspberry Pi2 y el software de Allstar corriendo en Archlinux.

New node made by K9MAR Omar with a RALI Interface. The RALI interface is a soundcard interface that can be purchased here: http://latinovoip.net/interfaces-allstar-r-a-l-i-de-k9mar/

This node is a Baofeng BF-888S, a Raspberry Pi2 and Allstar software runnung under Archlinux.
