Anyone here know more about D-STAR?  Basically all I know
about it is that it's digital and fairly expensive in that you need
to get all new equipment to use it (and tied to Icom hardware,
so how's that for a conspiracy theory. :-).

Thanks to a loan from Rhett KB4HG, RARS is testing a D-STAR repeater at
it's Bayleaf (north Raleigh) site. I encourage anyone with D-STAR equipment
to give it a try.

The frequency is 442.550. The repeater call is KB4HG  B (that's KB4HG space
space B). It will "auto-program" it's call in your radio if you have that
function turned on.

We are having some technical issues with the repeater. It does not always
repeat signals we believe it should be hearing and are properly programmed
with the repeater's callsign. And we have some noise from the tower light
at night that may be increasing the bit-error rate on received signals.
More use will help us observe and identify the symptoms.

Coverage is hard to predict. The antenna is at the top of a 250' tower,
with ground elevation at 500', right off of I-540 between Creedmore and
Six-Forks roads. North Raleigh should be good. Everywhere else is highly
terrain dependent. I've talked through it with a handheld in downtown Durham.

The repeater is coordinated to Chapel Hill, and will move there one day
after a bunch of testing. It had been on the air in Sanford for a few
months, behaving pretty well. The move to Raleigh introduced some anomalies
we want to understand.  The RARS 444.525 analog repeater is off the air for
the time being (this repeater uses that repeater's antenna).
