The W3DHS was placed in service in 2008 as a stand-alone Digital repeater. In August 2013 it was placed on the U.S. Trust system. The gateway server is running ICOM’s G2 software, DPLUS and the IRCDDB gateway add-on supporting fast updating of DPRSAPRS data and CCS call sign routing. The repeater is sponsored by the BaCo ACS group an auxiliary of the Maryland ACS organization.

Configuring your transceiver to access the W3DHS repeater and gateway via RF
Your ability to reach the repeater via RF will depend on the height of your antenna system, local terrain and transmit power. In some cases you will be capable of hearing the system but will not be able to access the repeater via your transmitter.
W3DHS C is currently linked to REF025B where it will remain linked to 25B for the foreseeable future. W3DHS B is linked to REF062C. The repeater is auto unlinked and linked during scheduled nets, scheduled exercises and emergency operations.
W3DHS is linked to the KB3TOG repeater. This link has has increased the effective range of both systems: Northeast through to the Maryland/Delaware border; north through to Lancaster, PA; east through to some areas of the eastern shore; south through to Alexandria, VA; west through to western Frederick, County.
To access W3DHS via RF:
My Call: your FCC assigned call sign
Your Call: CQCQCQ
Repeater 1: W3DHS C (module letter must always be in the 8th position of the Repeater 1 field)
Repeater 2: W3DHS G (the G is in the 8th position)
Valid values for the 8th position of the Repeater 1 field:
C – 2M module
B – 70CM module
A – 23CM module
If a “G” is not in the 8th position of Repeater 2 you will hear audio from linked gateways, however, when you key up your audio will not be routed via the gateway to the reflector. It will only be broadcast via RF on the local repeater.
Please Observe Proper D-Star Etiquette.
When operating on the repeater please announce yourself with “this is <your FCC assigned call sign> listening on ,W3DHS, over”. This informs other linked stations that you are not on their local system and the use of “over” indicates you are through transmitting and awaiting a reply. Remember D-Star repeaters and most D-Star radios do not use courtesy tones when a microphone is un-keyed.
When using a gateway enabled repeater conversations are broadcast over all repeaters linked via a reflector. Remember to pause between transmissions and wait at least five seconds after the station you are speaking with un-keys before transmitting to allow another station to break into the conversation. Pausing between transmissions also provides repeater administrators and stations an opportunity to unlink their local repeaters via RF.
When using a D-Star radio equipped with GPS, on a gateway enabled repeater, ensure that your radio is not set to automatically broadcast your GPS coordinates. If it is set to automatic the radio will transmit location information while others are speaking and interfere with their transmissions. Set your radio to broadcast GPS coordinates only when you key the PTT to transit audio.
Please use the contact form if you have any questions about D-Star or the use of the repeater system..
Enjoy the expanded system and coverage…
