ThumbDV™: DUTCH*Star Support Under Development

Fred (PA4YBR) at DUTCH*Star has been working on support for the ThumbDV™ in his Node DV/WinDV program.

It is now in beta test and working well.  Watch for more information at http://dutch-star.eu/

ThumbDV™: Now Shipping!

The ThumbDV™ first production run was completed and tested today and pre-ordered units will ship this week.  We have a bit of a backlog, so it may take a couple of days to ship all pre-ordered units.

To those who ordered in anticipation of the product, thank you for your patience.

This also means we have units in stock for new orders for shipment this week.

ThumbDV™: Ordering is Now Open

Now available from NW Digital Radio, a USB based version of the popular DV3000 AMBE™ vocoder board. The new product is the ThumbDV™ (model number DV3000U) and is available for ordering for $119.95, plus applicable taxes and shipping. Initial shipments for the ThumbDV™ are projected for the 3rd week of December, however, we cannot guarantee the shipment date until the production run is completed.

ThumbDV™

There are a limited number of ThumbDV™ units available in December, so get your order in early. We will do our best to ship in time for Christmas (US/Canada), pending any production delays. NW Digital Radio will be closed December 18th to the 29th.

Our DV3000 product, which is designed to be the vocoder for our forthcoming UDRX-440 digital radio, also acts as a popular add-on board to the Raspberry Pi single board computer and is now deployed in 25 countries around the world. This capability allows network communication through the Internet to the global D-STAR network using a computer with a microphone and speakers. The ThumbDV™ makes this functionality available on Linux, Windows, and Mac OSX* computers through a USB port in a thumb drive/dongle package. We invite developers to extend use to other platforms.

Current products in the AMBE USB space use the older AMBE-2000 series of vocoder chips which do not support additional digital voice radio standards such as DMR, System Fusion, dPMR, NXDN, P25 Phase 2 HR, and others, which can be addressed by the newer AMBE-3000 series vocoder chip as found in the DV3000 and ThumbDV™, pending further 3rd party software development.

* DummyRepeater performance is currently not satisfactory on OSX and ircDDBGateway has not been ported. We do not recommend purchasing the ThumbDV™ for exclusive use on Mac OSX at this time.

Watts Up with the UDRX

After taming some parasitic oscillation, the UDRX is now driving the Power Amplifier Module successfully. We’ll be optimizing the output filter and RX/TX switch next, which will require a minor board spin. Preliminary thermal analysis shows we’re in the ballpark for dissipation. We’ll have detailed analysis after the built-in monitoring is brought up and we evaluate Mitsubishi’s newer version of the module which has better shielding and thermals.

We still have a ways to go, but firing up the PA is a significant milestone.

Pacificon 2014

George, W5JDX,  from AmateurLogic.TV came by and interviewed John, K7VE, about our current and soon to be released products. Starts at 48:50

Delivery is in the eye of the beholder

Just finished showing the APRS 9600 Transmit Demo at Pacificon.

Dennis has the IQ Receiver socket pushing data thru to his workstation allowing post processing of the eye pattern. Here’s a snapshot:

At this point we’re pretty comfortable with accepting orders for the UDRX this year for delivery in Q1!

I will continue to post progress updates as we move forward.
