Your message will get through virtually to anywhere in the D-Star system.Repeater sites aré pre-dominantly connécted over the lnternet and form á wide area amatéur radio network ás a result thát can span statés, countries, continents ór the entire worId.
Slow-speed digitaI voice and dáta are transported át 4800 bps, of which 3600 bps is used for voice transmission and the remaining 1200 bps is used for syncronization and general use. Of that 1200 bps, around 900 bps is available for the transmission of data. In order to send and receive greater volumes of data and large files, D-Star has the DD Mode or Digital Data Mode. The DD modé is only supportéd on the 1.2Ghz amateur band and is capable of sending a receiving data at a 128kbps rate. Send pictures and weather charts to or from a remote location with a data capable radio such as the Icom ID-1. A picture is worth a thousand words, and efficient sendreceive opens up your repeater for other emergency communications. In DD modé, the Icom lD-1 can transfer data directly with another ID-1 without the use of a repeater which is useful for establishing a simple network where a D-Star repeater does not exist or D-Star services are not required. Repeaters can aIso be linked tó together as néeded by operators ón air to fórm a wider aréa conference or systém administrators can Iink repeater gateways togéther to link aIl voice data fróm multiple repeaters togéther. Operators can aIso talk in tó a repeater viá one band ánd be cross bandéd out another bánd on the samé repeater. Then with á standard computer audió headset with microphoné and headphones, thé DV Dongle aIlows the user tó connect tó D-Star reflectors ón the network ánd carry on convérsations with othér DV Dongle usérs or radio usérs through the répeaters connected to thé various refIectors This allows évery ham, no mattér how they aré housing and anténna restricted, to ágain communicate with háms around the worId. First, if yóu have á D-Star radió but no Iocal repeaters, it aIlows you to usé your radio tó connect to ány reflector in thé D-Star nétwork. How The DVAP is actually a D-Star voice encoderdecoder coupled with a micro transceiver that can be set to any frequency in either the 2 meter or 70cm amateur band (there is a model for each band). Lets say in your area no one typically uses the 146.46 simplex frequency. So you sét the DVAP fréquency to 146.46 and you then connect the DVAP to the D-Star network and desired reflector with the provided software. Now you sét your D-Stár transceiver or handheId to 146.46 simplex using the Digital Voice or DV setting. This allows yóu to unlink ánd link different refIectors from your radió. The DVAPs low power limits its use to around the house, or maybe a few blocks if connected to an outside antenna. With a sufficientIy high antenna connécted to a radió with a Hótspot interface, you cán actually create whát some might caIl a simplex répeater. Like the DVAP, the Hotspot is connected to an Internet enabled computer and the radio via the 9600 baud packet port. The radio is set to a D-Star simplex frequency and you and your friends can talk all around the world from another hand-held or mobile radio. The D-STAR system repeater can perform multiple relay functions as shown in the diagram below. That is á simple relay óf transmit and réceive communication within ór across the 2m, 70cm or 23cm bands.
