They have run into a few problems so stand by
The Dorchester County D-Star repeater system is NOT online. The system was funded by the county and I am told it is on a TV tower at 165ft. The Charleston County D-Star repeater is supposed to go online this weekend.
Dorchester UHF 442.8375 +
Dorchester VHF 145.280 +
All the above information came from Jason Morgan K4SHP & Phil Schreves N7GZT........
The UHF module is on the air now on 440.700+ as KJ4GGV. Please give it a try and let me know how it work from Beaufort County. They have ordered the VHF duplexer and the 1.2 triplexer and they will be on the air as soon as they arrive. It is not on the Gateway yet, but they hope to be on a temporary Internet connection very soon. I look forward to hearing from the area soon.

What is D-STAR?
D-STAR is a new ham radio system which offers digital voice and data communication. It connects repeater sites over microwave links and the Internet and forms a wide area ham radio network. The DSTAR system provides a new capability and functionality to the ham radio world and increases the efficiency of emergency communications.
What can the D-STAR system do?
128kbps digital data and 4.8kbps digital voice communication
The D-STAR system provides not only digital voice (DV mode) communication but also digital data transmission (DD mode). It can exchange various data files such as graphics, images, etc, at 128kbps.
Your voice and data can reach further than ever
Multiple repeater links by radio and the Internet provide long distance communication to virtually anywhere.
Internet application available
The D-STAR system uses the TCP/IP protocol, so when connected with a PC, web, e-mail and other Internet applications are available.
Wireless Internet Access
No matter where you travel within the DSTAR network, you can access the web, e-mail, text messages and multimedia messages.
D-STAR system will be upgraded
The D-STAR system will be enhanced and new D-STAR radios will be released, adding features and performance to the D-STAR system.
Digital callsign squelch (DSQL) & Digital code squelch (CSQL)
The DSQL opens the squelch, only when your callsign is received. When you share a single callsign with a club or group members, the CSQL function allows you to set a CSQL code from 00 to 99 and provides quiet stand-by while other members are talking.
EMR mode operation
When you require the attention of all stations in the area, the Enhanced Monitor Request (EMR) mode operation allows the caller to bypass the CSQL and DSQL setting of the receivers station. During EMR mode operation, all receiving stations will hear your audio, even though they may be muted.
Short message in DV mode
Short messages of 20 characters max. can be sent in DV mode operation.
Internet gateway relay
When D-STAR repeaters are connected with the Internet gateway, the D-STAR system relays the received data over the Internet. Microwave links and Internet gateways can be combined even during one contact. So your message will get through virtually to anywhere in the D-STAR system.
