Well, that was quick!
I was able to get an order in for one of the first batch of NW Digital Radio DV3000 boards... and it arrived on June 3rd! First shown to amateurs at the 2014 Dayton Hamvention, an initial run of one hundred DV3000 boards were made.
I had already installed the latest G4KLX Dummy Repeater software on my office PC (with support for the DV3000 as well as the DV Dongle) so all I needed to do was setup a Raspberry Pi with the DV3000.
I followed this excellent document written by Jonathan Naylor G4KLX and John Hays K7VE.
The first section of the document details how to prepare the Raspberry Pi for the DV3000. This consists of (a) increasing the clock to the Raspberry Pi UART, (b) disabling the getty (to allow terminal login) running on the Raspberry Pi serial port, and then (c) disable the console on the serial port.
You are then able to power down the Raspberry Pi and fit the DV3000 to the Raspberry Pi GPIO connector.
Then is the process of updating the Raspberry Pi operating system, installing required software libraries including downloading and building wiringPi.
Next you copy over the latest G4KLX AMBE Tools source code from the ircDDB Gateway Yahoo Group and then build the dv3000d AMBE Server daemon.
The resulting dv3000d executable can then be moved to a convenient location and started with sudo ./dv3000d.
sudo ./dv3000d -d will return control back to the console and leave dv3000d running in the background.
Once the AMBE Server is up and running, you can "point" the G4KLX Dummy Repeater or AMBE Tools software at the DV3000 equipped Raspberry Pi. It's a great alternative to the DV Dongle.
My only (little) issue with the DV3000 board is that it sits a little high. This is due to the piggy back connector arrangement that allows other expansion boards to be plugged into the Raspberry Pi/DV3000 combo. My DV3000 equipped Raspberry Pi won't fit into any of my cases! I am contemplating unsoldering the piggy back connector and fitting a lower profile one so I can fit it into my cases. I don't really need the ability to plug another board into the top of the DV3000.
If you have an early release Raspberry Pi board without the two mounting holes you will need to be careful with the 1/2" threaded spacer to ensure it doesn't short out to the Raspberry Pi PCB. It may pay to remove it if you have one of these earlier Raspberry Pi boards.
In short... I am VERY impressed with the DV3000 board. It works well, the build quality is excellent and the inital software support ensures you can have fun with it immediately.
