2018 – State of the Union

NW Digital Radio has been evolving over the last few years.  Our initial focus was to develop a 70cm radio focused specifically at higher speed digital communications for the amateur radio market.  This is still a goal, however, due to a series of conditions we cannot predict when this will happen.

While working on the various aspects of the radio we have been able to produce a series of products that have sustained the ongoing efforts of the company.

We have learned a lot in the process and will be taking that knowledge into new products going forward.

We at NW Digital Radio are problem solvers, and like the process of assembling a project from components, both hardware and software, and have delivered products based on that model.

For some products this model works very well, like our ThumbDV™, which has been very successful when used with software like BlueDV, WinDV, AMBEserver, DummyRepeater, XLX/ambed, and more.  Thousands are finding that the ThumbDV™ is just the right product at the right price point and are successfully using it to communicate from computer, over the network, to Digital Voice protocols such as D-STAR, DMR, and more.

Other products, such as the UDRC and UDRC II, have allowed the creation of digital communications systems whether D-STAR repeaters,  fldigi workstations, Direwolf sound modem TNCs, or other soundcard DSP based systems.  Many of these projects have come about by experimentation and integration by individual amateurs working with open source software and our boards.

However, as we talk with customers and potential customers, we find that many are more interested in solutions that are prepackaged with hardware, software, and a case.  Basically, they want a “plug and play” solution that requires little to no integration beyond basic cabling to radios and some minor, guided, configuration.

In 2018, you will see NW Digital Radio evolving from a component provider to a solution provider.  We continue to be dedicated to products that leverage open source software and standard platforms, but will be focusing on delivering solutions that are pre-integrated with hardware, software, and packaging.

We will also continue to provide the experimenter and developer a platform that they can access and build upon.

Furthermore, we intend to use the kick starter model on some products where there appears to be an interest in the community, but where we need to know the level of that interest before proceeding with full inclusion of an idea into our product line.  If you find a product on our kick starter list, please support it, the risk to you is minimal, while helping us bring out innovative solutions.

Some of the projects we have under design at the current time include:

  • A networked, multi-speed, TNC for packet radio
  • An Emcomm workstation
  • A device for combining multiple SDR-RTL dongles into a single platform
  • An integrated low power radio/TNC

and more.

Look for these projects to roll out over the next few months.  We think 2018 is going to be a great year to continue to put “The Amateur back in Amateur Radio” —

Kickstarter for a 6 Channel USB AMBE Device

We are pleased to announce the launch of a Kickstarter for a 6 Channel USB AMBE device which is compatible with the XLX Reflector System.  The XLX system creates reflectors for the DCS, DExtra, and DPLUS systems and also supports integration with DMR.

To transcode AMBE+ (D-STAR) and AMBE+2 (DMR/YSF/dPMR/NXDN/P25-Phase 2/…) requires a hardware solution.  This can be accomplished using pairs of ThumbDVs or other USB based AMBE-3000 devices.

Reflector systems may have multiple reflectors (A-Z) that require transcoding simultaneously, which requires multiple streams available and that is where the XCode-3006 comes to the rescue.

The folks behind the XLX system designed a board that can provide up to 6 streams on a single USB port and it is in operation now at XLX950 (XRF950/DCS950/…) which is using the board to cross connect with DMR.

NW Digital Radio is running a Kickstarter to fund an initial build of 50 of these units. 50 units is the minimum production run in order to keep costs down.

This is where you can help:

If you run a reflector, you can obtain a XCode-3006 via a pledge on the Kickstarter at one of two levels.

If you use a reflector, you can help the operator of that reflector by helping them obtain a XCode-3006 via the kickstarter.
If you just like the idea of a six channel AMBE transcoder, and want to help out, there are pledge levels for supporters like you.

This can only happen if we meet the funding goal set for the Kickstarter, and we only have 30 days to reach it.

Having this board available opens the opportunity for other projects such as:

Analog <–> DV Gateways (eg. Allstar, Echolink, … to your favorite DV system)
DV –> Analog Streaming for online monitoring of DV systems

UDRC D-STAR and the Yaesu DR-2X

At the current time the Yaesu DR-2X is not supported for D-STAR using the UDRC/UDRC-II.

Universal Digital Radio Controller

Please use the DR-1X for D-STAR with the UDRC/UDRC-II

Special Pricing on the Purchase of Multiple ThumbDV™

AMBE USB 3000 ThumbDV™

ThumbDV™ – DV3000U

AMBE USB 3000 ThumbDV™

ThumbDV™ – DV3000U

There are some projects that are using multiple ThumbDV™ to handle transcoding digital voice data from one protocol to another.

In support of these projects NW Digital Radio is offering a 5% discount on the purchase of 2 or more ThumbDV™ on the same order, to the same address, through the end of 2017.

To receive this discount, simply order 2 or more ThumbDV™ and in the shipping cart input the coupon code transcode and the discount will be applied to your order.

If purchasing more than 10 items (ThumbDV™ or UDRC) on the same order, contact sales@nwdigitalradio.com to inquire about quantity discounts.

UDRC II – Notice of Possible Programming Error

We have discovered that some UDRC IIs have shipped with a EEPROM programmed to identify it as an original UDRC.

Please review the wiki post at https://nw-digital-radio.groups.io/g/udrc/wiki/UDRC-II-EEPROM-Flashing for details on identifying and correcting this error.

Hamvention 2017 – Dayton

We will be at booth 1105 (Bldg. 1 – next to Bridgecom) on Friday and Saturday this year.

We will not be at the Hamvention on Sunday.
We will have a limited number of ThumbDV and UDRC-II units for purchase, and maybe have a little something new to show you (not the the UDRX-440).

The UDRC-II Enables D-STAR on Many Repeaters

In case you missed the updates on the UDRC Wiki, there are now examples of adding D-STAR using the UDRC-II on many different repeaters:

Universal Digital Radio Controller

Yaesu DR-1X (currently available directly from Yaesu on a special promotion)

Kenwood TKR-750/850

Bridgecom Repeaters (including the 220 band)

Homebrew Systems

Use the message board to share your repeater and hotspot implementations using the UDRC or UDRC-II

If you can get at the discriminator and true FM modulator of a repeater, the UDRC-II gives you a way to add D-STAR.

Holiday Sale on ThumbDV

The ThumbDV™ is on sale through December 25th for $99.95, that’s a savings of $20 over list price.

9.6Kpalousa

It’s time to move from 1200 bauds (it’s been 38 years).
NW Digital Radio will setup a test bench at the Northwest APRS Summer Gathering (Sep 9-11 at Valley Camp) to help get stations operating at 9600 baud packet.  This is your opportunity to get your equipment up and running on 9.6K packet.
We will have spectrum analyzers and deviation measurement equipment setup to make sure your configuration is optimal.
Bring your 9.6K capable hardware or software TNC, your radio, connection cables, and documentation on adjusting the radio’s deviation and TNC levels.
If you don’t have a 9.6K capability.  We will be offering the UDRC for sale on site (or pre-order).  You need to provide
  1. A Raspberry Pi 2 or 3
  2. A 9600 baud packet capable radio with appropriate cable
    • Mini Din 6 on the UDRC to your radio’s interface
    • We will bring a soldering station if you need to put a connector on a Mini Din 6 cable,
  3. A micro SD Card, preloaded with Compass Linux and direwolf
    • We can load your SD Card on site.
  4. A power supply for the radio and the Raspberry Pi (3A recommended)
There will also be examples of messaging applications as well as APRS applications available for running on the Raspberry Pi.
