2m WINLINK gateway HB9AK-1 adds VARA FM

Submitted by HB9AK on Sat, 2018-07-07 21:14

The 2m 'multispeed' gateway HB9AK-1, that is offering packet radio access to the WINLINK network with different modulations and speeds (AFSK 1200 Bd, BPSK 1200 Bd, BPSK 2400 Bd, QPSK 2400 bps, QPSK 3600 bps) has now added VARA FM (both 1200 and 9600) as additional modes of operation. The gateway listens in all modes for connect requests and answers in the respective mode. VARA FM (9600) reaches a throughput of up to 80 kBytes/min, a more than ten fold increase compared to conventional packet AFSK1200.
For connecting HB9AK-1 in VARA FM, use direct de-/modulator access in your FM rig for both modes (1200/9600).

Amateur Radio Safety Foundation, Inc.

Winlink Global Radio Email®️ is an all-volunteer project of the Amateur Radio Safety Foundation, Inc. (ARSFI), a non-profit public benefit corporation with no beneficial owners.

Please give to ARSFI if you use Winlink radio email or correspond regularly with someone who does. By donating $25 each year you will do your part to improve this system and keep it running. Donations are tax-deductible by most US federal taxpayers. This is the best way to say "thank you" to Winlink volunteers! You can also purchase a registration key for your Winlink Express software. That's different than a donation! And is another way to contribute.

WANTED:

Outstanding Volunteers

The Winlink system is run entirely by volunteers. Those called Gateway Station Sysops, who support and run over a thousand stations around the world, are special. They are essential for providing the radio network that allows us to use Winlink radio email. Without them, there is no Winlink. If you use Winlink radio email, make sure to thank your sysops by sending them an email to their RMSCALLSIGN-at-winlink.org address.You can find their contact information by mousing over their call sign on the RMS List tab here.

Apart from the Gateway Station Sysops and Development Team, there are other volunteers that run e-mail groups and tutorials, manage user accounts, register software, update the network's assets and catalogs, test and debug products, provide training, and independently write software. They all work together to keep the Winlink system running smoothly. Thank you to all the hardworking volunteers, authors and developers who contribute to the Winlink system. Some are exceptional and deserve special praise:
