What is DRAWS

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.”

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” —

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

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.

Pi Cases are back in Stock!

The new supplier has shipped cases so we’ll fill all of our backorders this week.

The price has increased to $15 for new orders.

Thanks for your patience.

Pi Cases – Delivery Update

We received the first article from the new supplier and the design needs tweaking so that the tabs will assemble correctly. We have a new sample in process and I’l keep you apprised.

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.

Pi Cases for the UDRC-II

The Pi cases were designed and supplied by Budd Churchward, WB7FHC. Budd laser cuts the acrylic at a local DIY cooperative here in Washington.

Over the holidays the coop moved and they’re not back on line yet so we are working on alternative suppliers. We should have a first article next week and will be back in stock mid February.

If you have a case on backorder or order one now with a UDRC-II, it will be shipped for free as soon as they arrive.
