Universal Digital Radio Name Change to UDRX-440


NW Digital Radio has renamed it's forthcoming digital radio platform. Since
its inception, the Universal Digital Radio was designed to be a
multi-application, multi-protocol, and multi-mode digital radio platform.


When announced at Hamvention® 2012 , the radio design focused around a high
integration “radio on a chip” platform that provided both the RF section as
well as integrated modems. The selected device proved to be somewhat
limited and did not meet the high expectations of the design team and was
later abandoned in favor of a modular design that separates the RF and
modem stages.


The new design provides an I/Q interface for detection and modulation of
the RF signal. This affords maximum flexibility for a software defined
modem system, providing a variety of modulation choices at varying data
rates, thus freeing the radio from the fixed modulation and data rate
choices of the earlier design.


When the radio was first announced it was targeted to a maximum data rate
of 56 kilobits per second, based on available modulation choice and the
limitations of the US regulations for amateur radio on the 70 cm band. The
model name of UDR56k-4 was chosen to reflect this set of specifications.
Now that the design allows for additional modulation choices, higher data
rates are available within the specified bandwidth and, along with proposed
rule changes before the US Federal Communications Commission, has prompted
NW Digital Radio to increase the data rates available on the Universal
Digital Radio platform.


The company re-opened the naming of the product, seeking input from its
growing user interest group, and has adopted a new naming convention. The
first radio design is now designated the *UDRX-440*. This model is a
430-450 mHz digital radio with integrated software defined modems, protocol
engine, and Linux application platform.


NW Digital Radio is currently accepting order commitments from individuals
who participated in the Q2-2013 pre-order process. Ordering will be opened
to the general amateur community in late Q1 or early Q2-2014 with delivery
anticipated in mid to late Q2.
