I have been experimenting with D-Star on HF with a friend of mine who is abt.
6 miles away as the crow flies. This works on 10m. There are some 10m D-Star hotspots
coming online in Germany now, and I'm hoping for a repeater/gateway. Don't know
about the U.S. activity. 73, Alex-DH2ID

International DSTAR HF Testing NetWinter Schedule –

Use your ICOM 9100/7100, or STAR Boarded non ICOM DSTAR HF, or the FLEX 6000 series radios with software 1.5 or better and the DV3000 card.

Here is some video of DSTAR HF Voice simplex on a 7100

We routinely have two way communications coast to coast and North to South, South to Canada, Europe and Australia. We have had two way contacts to Japan. And have been heard in South Africa.

We are on each band only for 5 min. or so as to spend less time, if the band is dead we move on earlier. You can go back to a good freq after the net.
MONITOR REF030C to coordinate. WE may need to move early or if the freq is busy. We do not want to step on any AM or SSB activity.

We also use a web page to keep track of who and where we are at -

You also can check-in to this web site anytime 24/7 to find a DSTAR HF Ham to talk to.

We will have a PRENET for 30 min. before the start of the scheduled time. This PRENET is for ‘FREE FORM” contacts. One should check the web site  sign in and find a working freq to work on. When the net starts at the scheduled time, please join the net and follow the freqs.


Sat PM 7:00 E (2400Z)

Sunday AM 10:00 E (1500Z Sunday)(Spend more time on each open band, and start on 80m)

Sunday PM 7:00 E (2400Z)

Tuesday and Thurs night at 8:30pm E (0130Z Wed and Fri)

Check USB/LSB on freq to make sure the freq is clear.
SUNDAY AM, we start with 80m and work towards 6 meters.

h:00 - h:05 6 mtrs 51.180 DV for 5 mins

h:05 - h:10 10 mtrs 29.480 DV for 5 mins

h:10 - h:15 12 mtrs 24.938 DV for 5 mins

h:15 - h:20 15 mtrs 21.380 DV for 5 mins

h:20 - h:25 17 mtrs 18.148 DV for 5 mins

h:25 - h:30 20 mtrs 14.325 DV for 5 mins

h:30 - h:35 40 mtrs 7.285(or another open freq) DV for 5 mins

h:35 - h:40 75 mtrs 3.880 DV for 5 mins Backup is around 7.300. THIS ALSO APPEARS TO BE AN AM FREQ

NCS will check the freq ahead of time to make sure we don’t step on anyone 3KC up and DOWN.
