If you followed my previous posts and set up the Icom Remote utility the you are now well on your way to wirelessly connected operation of your Icom IC-705, so you will now be setting up client software to use the radio.
In this post I will share the settings for Winlink Email with VARA HF modem. There are not many settings the key ones are the COM Port for CI-V and Sound Device.

First VARA HF Winlink Radio Settings.
Ive selected Icom 7300 as the radio model, this radio uses the same or similar CI-V commands as the 705.
Icom Address which is the CI-V address should be set to A4.
If I remember correctly the remaining settings here are as default.

In the VARA HF Soundcard settings we just need to select the ICOM Virtual Audio device, this is the only setting I updated.
Using the above settings my winlink email works perfectly using the radio over HF.
Hope this helps
