VARA HF Winlink Express E-mail Over HF
VARA HF is faster than ARDOP. To get the full benefit of VARA you will need to purchase the upgrade. I have not done that because the free version works FB. I’ll go over the installation, settings and use below. It is fully integrated into Winlink Express.
See my previous article on Winlink Express ARDOP E-Mail Over HF.

VARA HF Tips
TIP #1 Use “Slow AGC”
TIP #2 Receive bandwidth should be wide enough to extend outside of the red guide lines.
TIP #3 When sending an e-mail you can put “//WL2K” without the quotations as the first word in the subject line and it will bypass SPAM filtering in the Winlink system.
