[d-star] d-star update

[Erik Jacobson]

A couple minor d-star updates...

Working with a friend of mine (K0TG), I have changed the club call for the 
d-star system at 443.450 to be K0UW (renewed today).

I'll be able to use that long-term.  Thanks to Matt for letting me borrow
W0USD.  This means I'll move ahead learning about the gateway software one
of these evenings.

I installed the VHF RF deck and a 2-meter duplexer should be here on Friday.
Right now, the transmission antenna is a 30 watt dummy load.  It turns out
it doesn't get out so well right now :)

The duplexer won't be available instantly as it needs to be tuned and I need
some other parts I haven't ordered yet; but soon!

I'm not exactly sure what frequency pairing it will end up with yet; but I'll 
let you know when it sprouts up on the air from my house.  It may be something
strange at first.

Also, I de-coupled my 220MHz machine from my equipment rack.  It's still
sharing the power supply but is otherwise separate.  So if the d-star stuff
ever moves to a new home, it won't be tangled in to my other system so bad.
(This is more for the benefit for the folks who stopped by my house to
initially set it up).

I haven't talked to many people yet but I had one long conversation with
a friend that lead me to believe the current coverage is either as good or
better than my original UHF system.  I don't have scientific data though.

Thanks :)
