G4KLX creates new FM Repeater Controller software with UDRC Support

From the repository at https://github.com/g4klx/FMRepeater

“These are the source files for building the FMRepeater. This is a simplified version of the old Analogue Repeater that has existed on the OpenDV GitHub repository for many years. It has the following features:

  • Seperate id and beacon texts.
  • Timeout can be one of three styles, or no timeout.
  • Optional callsign at repeater open or close, or both.
  • Id may be suppressed if too close in time to a previous id.
  • Optional kerchunk timer.
  • Selectable acknowledgement style.
  • All ids and acknowledgements have selectable frequency and speed.
  • Minimum talk time before an acknowledgement is sent.
  • Built-in string audio bandpass filter.
  • Repeater control via an Arduino or a UDRC.
  • Audio I/O via any supported sound system, including the UDRC.

It builds on 32-bit and 64-bit Linux as well as on Windows using Visual Studio 2017 on x86 and x64.page on the LCDproc website for more info.”

G4KLX adds UDRC support to MMDVM

From the repository at https://github.com/g4klx/MMDVM-UDRC

“This is the source code of the MMDVM program/daemon that supports D-Star, DMR, System Fusion, P25, and NXDN modes via the UDRC Pi interface.

It will provide all of these modes in simplex mode, and all bar DMR in duplex mode. It is not possible to get DMR to operate in duplex mode via the UDRC. If you want full duplex in all modes then you will need to run a full MMDVM system including hardware.”

Help NW Digital Radio with your view on GPS for next generation UDRC

NW Digital Radio is seeking input for the next Raspberry Pi based Amateur Radio digital station platform.

The new Raspberry Pi HAT will contain a CODEC (sound card) based on the successful UDRC II and will include two amateur radio packet standard mini DIN-6 ports allowing one or two radios to be connected with PTT and SQL detect and support programs/protocols such as:

Direwolf – providing multi-speed packet radio modems (2 channels) [APRS, RMS, Xastir, URONODE, …]
wsjt-x – K1JT family of digital modes including FT8
fldigi/flrig/… – digital modes
dstarrepeater – D-STAR hotpsot/repeater
and more

This will be an integrated package, in a custom case, with available pre-built images requiring minimum configuration.

Please participate in the survey, and give your opinion on GPS integration. It is only one multiple choice question and should only take a minute of your time.

Take the Survey

Thank you.

Feel free to forward this email to appropriate individuals and mailing lists.

Last Chance for the XC-3006

Today is the last day to order an XC-3006 6 Channel AMBE Vocoder. We’ve received 22 of the 25 orders required for an assembly run. We need 3 more to make the run.

If you are one of the 30 Kickstarter Backers and you haven’t received your discount coupon please email me.

Thanks,

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” —

Your NW Digital Radio team.

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

The link to the Kickstarter is:

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
