A New DV4mini Arrives On Scene

DV4mini USB StickWireless Holdings sells leading edge modules and accessories to Ham Radio operators. Wireless Holdings has been in the digital gadget market over 40 years, and leverages a network of professional engineers to bring the latest digital gadgets to the market.

Why would anyone be interested in a DV4mini USB Stick? First I should explain that the DV4mini is a miniature, low power transceiver which you can use around the house or portable with any HT capable of one of the four digital modes. DSTAR, DMR Plus, Fusion or P25. Download a copy of the DV4mini manual for more detail.

In my case, even though  I live in an area tightly packed with analog RF, there are no digital repeaters close enough to reliably access with an HT. Unless I connect my CS700 to my roof antenna, I cannot reach the DMR TRBO repeater in my area. Visit DMR-MARC if you want to know more about TRBO for Ham Radio.

So using DMR with the DV4mini (although not TRBO) gets me connected to the digital world using DMR Plus (Hytera systems). I cannot speak about DSTAR, Fusion or P25. My only experience has been using DMR Plus. I don’t spend a lot of time with the DV4mini however I had the pleasure of having a QSO with a Ham from Japan a few weeks back.

My 70cm DV4mini has worked flawlessly since I purchased it some months ago. As I mentioned in a prior article, I built up a Raspberry Pi with the necessary software to run the DV4mini console. If anyone is interested in my notes about building up the software necessary to run the DV4mini Console and other Raspian Jessie ramblings,  stop by my homebrew Ham Radio Forum.

Recently I received an email stating that Wireless Holdings will start selling the DV4mini  in a 2 meter version. Just in time for Dayton Hamvention!

Install DV4Mini Console On Raspberry PI

DV4mini Console SoftwareAs a retired ‘NIX Systems Admin I still have to find out what makes things tick.

So I decided to build a Raspberry Pi 2 model B using a 32Gb Micro USB Card and the vanilla copy of Raspian Jessie 8 into a fully working DV4mini Console.

I used Putty with the DHCP provided IP address to run raspi-config expanding the file system and to change default localization settings.

Then it was on to installing x11vnc so I could work from my Windoze desktop using Tightvnc. Next it was getting the Edimax Wireless card online. From there I installed Mono 4.0 (Note: an 8GB Micro USB Card will run out of space while installing Mono 4.0) and finally the DV4Mini Console.

Since I created a series of crib sheets, I put a home-brew forum together as a central repository for my notes.

For those interested, go straight to my work-in-progress forum at KE2YK’s Ham Radio and Systems Forum. BTW, You don’t need to register to poke around its contents.
