The AR Newsleine carries a report about a D-STAR net on 7.215 MHz
The report suggests if you have interest in digital audio on the High Frequency bands you might want to tune your D-Star equipped transceiver to 7.215 MHz at noon UTC. This to see if you can take part in a D-Star test net operating from Australia most mornings.
The net control is Brian Farrar, VK2AH, in New South Whales who says the best contacts so far have been from his location to the city of Horsham about 550 miles away. Farrar says that net participants have tried other bands with no much success but 40 meters seems promising.
VK2AK is not only on for the net but also tries 40 meter D-Star at other times of the day as well. While operating he also monitors D-Star Reflector REF003 and does put out alerts when he is looking for D-Star contacts from his QTH down-under. (VK3TOM, D-Star Remailer)
The Emission Designator of a D-STAR transmitter is understood to be 6K00F7W. This indicates a Necessary Bandwidth of 6 kHz. An article by the Utah VHF Society on D-STAR occupied bandwidth and channel spacing can be seen - http://www.utahvhfs.org/dstar_channel_spacing.html
