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.

Installation

Even though it is integrated into Winlink, you will still have to install it. It is easy to do.

The download link is here: VARA Modem.

Settings

After installation, you will see it in the drop down list under “Open Session.”

The first time you open it you’ll have to do some setup. See my screen captures below:

 

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.

I'm an Amateur Radio enthusiast. I love the hobby and experimenting with radios, antennas and software. On my YouTube channel I upload videos on the Icom 7300 and Icom 7610 along with Ham radio software programs. I hope to inspire people to try new things in Amateur Radio.

    Aside from the 2 monthly costs there seems to be no others. I remember WINLINK modems being way overpriced and beyond practical justification. Other than the 2 subscription costs are there any additional other than the an existing “normal” ham station assembly? N3HKN

    Hi Richard,

    Nice to hear from you and thank you for commenting here. Correct me if I am wrong, but registration fee for a key to Winlink Express and VARA are one time, not monthly.

    Just purchased VARA so I’ll let everyone know what the difference is.

    I hope all is well with you and yours, please take care and best 73!
