Hi all,
Below is info from the Icom America web site on the DStar rigs. They work
on the 1.2ghz band, so I'm probably not interested. I was looking for
narrow band digital voice on the low bands. Here's the info.

Fundamental Plan of the D-STAR System
The D-STAR system is an off the shelf, 128K open protocol DATA system that
combines
the analog and digital worlds into a seamless communications network at 1.2
and 10
GHz! Just picture being in your vehicle, helping with emergency
communications with
the 128K DATA - you can visually communicate what is happening simply by
e-mailing
a photo or live video. "A picture is worth a thousand words." The power of
the D-STAR
system is limited only by your imagination!

While the ID-1 transceiver is a vital part of a D-STAR system, you won't
have to
wait for a new repeater to be set-up in your area. This rugged little rig
operates
with current analog 1.2GHz repeaters, plus simplex digital operation with
another
ID-1. Its operating frequency range is 1240-1300 MHz, with FM and GMSK
(Digital)
modulation formats. The ID-1 includes all the usual features that you
expect - 105
alphanumeric memory channels, PLUS full PC control via the USB port (a black
box
1.2 GHz radio!). Now for the fun part... the ID-1 supports a 10BASE-T
Ethernet cable
for the 128K DATA operation! Explore the benefits of wireless high-speed
integrated
digital connections! See your authorized Icom dealer - the future begins
today!
Icom is the first manufacturer to introduce products for this innovative
communication
system. The ID-1, ID-RP1, and ID-RP1L are the basic building blocks for this
system.
The ID-RP1 and ID-RP1L, are the repeater and backbone components of the
D-STAR, while
the ID-1 can be configured as either a mobile radio or base station.

A Brief History of D-STAR
Although our D-STAR products are newly introduced, the D-STAR project dates
back
to 1998.
