ARLA/CLUSTER: Australia em D-Star chama em 7215 kHz banda dos 40m

Australian D-STAR on 40 metres

Amateur Radio Newsline carries a report about a D-STAR net on
7.215 MHz

AR Newsline say:
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
