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.

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.

The $800 Tri-Mode Repeater: UDRC™ + Yaesu DR-1X

UDRC™ – New Wiki Post

There is a new Wiki entry on using the UDRC™ on packet radio with the direwolf soundcard TNC

See: Wiki Post

Using the UDRC™ + Raspberry Pi 3 + 7″ Touchscreen Display + a FT-817 (or other radio) makes a great little desktop Xastir based APRS viewer.

Hamvention® 2016 – UDRC Rollout

Members of the NW Digital Radio team just returned from Hamvention® 2016 in Dayton, OH.

We had a Yaesu DR-1X repeater setup on 440+ running System Fusion Digital, Analog FM, and D-STAR using the UDRC in conjunction with the DR-1X’s internal controller.

The booth is located very close to the exit of the main Yaesu booth and a lot of folks passing by noticed the repeater and when the functionality was shown, most who owned a DR-1X immediately purchased one or more UDRCs.

Xastir + Direwolf were also demonstrated using a FT-817 transceiver and UDRC board.  This combination can be configured and operated at either 1200 or 9600 baud packet.

Software and instructions for the UDRC will roll out in the next few days.  It was necessary to repackage the Compass extension to Raspbian due to changes made by the Raspbian development team.  All users of the UDRC need to use the Compass distribution as their operating system to support the necessary drivers.  The code will be available as open source via Github for those interested in the enhancements.  Also, please use the Compass distribution for dstarrepeater package if using the UDRC for D-STAR either as a hotspot or as part of a repeater.

More to come in the coming days and weeks.

We would especially like to thank our UDRC beta testing team for valuable field experience and feedback.
