Hi Dave,
I was only repeating what I heard from another ham who was working
commercially with the APCO P25 standar who was expressing his opinion of the
DStar radio. I would not buy one because it has not become standardized
with other manufacturers.

The Icom radios use a completely digital mode at 4.8KBPS. 3.600KBPS is used
for the voice while 1.200KBPS is used for forward error correcting and other
data. The low-speed d-star takes up 6.25KHZ. The high-speed d-star data
mode can transmit at 128MBPS on 1.2GHS. The bandwidth is 1.25MHZ. Check
out more specifications on the Icom America webpage.
