Hi Marlin,
Well you have a nomenclature problem - DD (Digital Data) refers to the
Ethernet encapsulation within D-STAR protocol at 128K and is only
currently available on 23cm using the ID-1 radio (and RP2D module).
If you key your mike and the repeater comes back with an ID, you have
basic configuration correct for your radio (IC-2200H + UT-118 is
probably the most primitive and lowest functionality of any Icom D-STAR
radio, save maybe the V/U82 handhelds). D-STAR radios that are not
linked to a busy reflector can be notoriously quiet - so put out a few
CQs on the repeater to see if anyone is out there. (If everybody just
monitors and never talks, the repeater will sound empty).
As far as D-RATS goes, it uses DV-DATA (sometimes called "slow data").
DV-DATA is a bit-stream that is combined with the digital voice stream
and provides about 950 octets per second of half duplex data traffic.
What KK7DS has done with it is truly remarkable. In most areas, on air
D-RATS is usually on simplex or via pre-arranged schedule. Your best
support for D-RATS questions can be found at

Welcome to D-STAR.

I need help. I have an ICOM IC-2200H with the UT-118 freshly
installed. I have a gateway account on my local D-Star repeater. I
logged on and I think I checked all the boxes and got one IP.
I "think" I have configured my 2200H correctly.
I sorta understand the DV, but I never hear anyone on the radio.
I am primarily interested in DD. I have D-Rats installed on my
computer. I can connect to the def.d-rats.com ratflector. I also made
a serial cable from the ICOM to my computer. D-Rats connects to the
radio and when I "ping" or "chat", the ICOM hits the repeater, BUT I
never seen any other stations (unlike when i'm on the RAT PORT).
I was hoping all the DD (D-Rats) users on all the linked repeaters to
my local repeater would pop up and I could chat and email them. Am I
doing something wrong or am I totally confused about D-Star and what
it can currently do???
