UDRX Pilot Boards have Arrived

After dealing with component shortages and Holiday schedule, the UDRX pilot boards arrived this afternoon from our assembly house in Renton WA.

The boards now go into the lab for initial bring-up, then they will be split into 3 task groups:

  • SW Driver additions and updates
  • IQ audio and RF path
  • PA and RX/TX switch

There are a substantial number of relatively minor changes to the design, in addition to the major change in form factor to accommodate the switch to the R-Pi 3.

I will provide an update on our progress by Hamcation in Orlando next month, where the pilot units will be on display. There is still significant work ahead, before we can determine if the pilot run can move to production.

Thanks for your patience and support,
Bryan K7UDR

UDRC: The Linux in the Ham Shack Interview

The good folks at the Linux in the Ham Shack podcast interviewed John (K7VE) about the UDRC and other topics.

The segment starts at minute 16:30 of podcast #166

UDRC Status

The UDRC Rev 2 is now operating in the field with our Beta sites. Rev 3 pilot run should be completed this week and, pending confirmation, we will release it to production next week and start accepting orders.

We’ll be demoing the various modes at Dayton Hamvention. Stop by and see us at Booth EH0515 right around the corner from Yaesu.

Native MacOS Application for ThumbDV™ and PiDV™

 

 

Buster on App Store

 

Jeremy McDermond, NH6Z, undertook writing a native application for Mac OS® and it is now available on the  Mac App Store.

Buster is not a product of NW Digital Radio and support requests should go directly to Jeremy.

Jeremy has stated that the source code will be made publicly available via GitHub and he is open to collaboration for future versions.

It works with a ThumbDV™ on a Mac OS® USB port and with AMBEserver™, locally or over a network.  AMBEserver can support either the ThumbDV™ or PiDV™.

This application has been in beta for several months and is both stable and feature rich.  It takes advantage of several Mac OS® specific services.  For example, it will use Apple Core Location service to determine your current location and reports it via D-STAR.  It also provides mapping of remote stations who are reporting position.

There is one known issue:  The way that Mac OS® powers USB ports during its sleep state may cause communication issues with the the ThumbDV™ upon wake up.  Most casual users will not experience this condition. The condition is resolved by removing and re-inserting the ThumbDV™ into the USB port.  Linux and Microsoft Windows sleep state does not exhibit this condition.  Since FTDI USB drivers are not written by NW Digital Radio, buyers of the ThumbDV™ should consider this when making a purchase decision.

UDRX does Raspberry Pi 2

We have moved from our custom linux SBC to the Raspberry Pi 2. This has a number of advantages:

  • Higher Performance
  • Lower Cost
  • Better Software Support
  • Easier for Developers to migrate SW to the UDRX
  • Future processor migration path, assuming header pinout compatibility

Of course nothing comes for free and there has been additional SW work migrating from a 3.x to 4.x kernel. Packaging has also been affected, but the overall package is simpler and better for final assembly. We are testing now using our existing RF Deck and a 40 pin adapter cable.

We are engaging with a Contract Manufacturer for Turn-Key Production, including custom extrusions. Engineering is moving forward towards a pilot run, once the Pi2+RF Deck is qualified at full power.

Expect the next update in January

Jeremy McDermond joins NW Digital Radio

Jeremy McDermond, NH6Z, has joined our team.  Jeremy is Vice President and a member of the board of directors of TAPR (www.tapr.org) and well known in the amateur community for his work with Software Defined Radio (SDR). He is author of Heterodyne, a software defined radio application for MacOS X and iOS devices supporting the OpenHPSDR (www.openhpsdr.org) project hardware.  Jeremy’s latest creation is Buster, a recently released application supporting the ThumbDV and PiDV on MacOS X.

You may have seen Jeremy speak at a variety of conferences including Dayton Hamvention, MicroHAMS digital conference and TAPR/ARRL Digital Communications Conference.  He has been active in the Summits on the Air (www.sota.org.uk) hiking to the tops of many mountains in the Northwest United States to make QSOs with his trusty KX3.  He also operates the T2OREGON APRS-IS server.

When not immersed in ham radio, Jeremy serves as Network Engineer for a small web hosting provider in Corvallis, OR and has been a UNIX systems engineer for nearly 20 years.  He is also a member of the Oregon State Bar Association and practices law in a variety of fields.

We are excited about adding Jeremy’s skills to the team and look forward to his contribution to the UDRX and other products.

FlexRadio Systems® and NW Digital Radio Offer D-STAR Compatible Solution

FlexRadio Systems®, the premier manufacturer of amateur radio SDR transceivers, will soon release an update to their SmartSDR™ software in support of the JARL’s D-STAR standard through installing the ThumbDV™ Waveform Module into SmartSDR™.

Owners of FLEX-6000™ Signature Series transceivers may add AMBE encoding/decoding to their radios by inserting the ThumbDV™ into one of the available USB ports.  Use of D-STAR digital voice mode will then be enabled through SmartSDR™ software.

“The partnership of NW Digital Radio and FlexRadio Systems forged at DCC last year has yielded a unique opportunity for FlexRadio owners to add the D-STAR mode to their FLEX-6000, as a component of our growing digital voice offerings.” said Steve Hicks, N5AC, VP Engineering for FlexRadio Systems®.

“It’s been great working with Flex to add D-STAR to their world class SDR and are excited about being a part of their ongoing development of digital voice modes.” said Bryan Hoyer, K7UDR, CEO of NW Digital Radio.

HF D-STAR is a growing mode with daily nets on all bands from 80-6 meters, as well as local VHF/UHF simplex and repeater networks.  For more information about HF D-STAR net operations please visit D-STAR HF Net

A real-time HF QSO finder can be found at HF D-STAR QSO Finder

The NW Digital Radio ThumbDV™ digital voice dongle will be available directly from FlexRadio Systems®, as well as from NW Digital Radio.

John Hays (K7VE) from NW Digital Radio and Steve Hicks (N5AC) from FlexRadio, will be available for questions, at the Huntsville Hamfest.
