Winlink Express and VARA HF modem software over PowerSDR KE9NS v2.8.0 and the Flex-5000 SDR

NOTE: Best viewed in 1080p or 4k

This is a quick video showing successful operation of Winlink and VARA HF modem software, using a Flex-5000 running PowerSDR ke9ns v2.8 software to send an email over HF radio.

A "Virtual Audio Cable" (VAC) is used to link the Audio between PowerSDR and Winlink/Vara software. I use Voicemeeter Banana drivers.

A CAT com port pair is used to link the PowerSDR and Winlink/Vara software for frequency, mode, power level, etc. I use VspMgr for creating COM port pairs.

PowerSDR VOX is used to PTT the radio. If you do not have VOX capability, try using the COM port PTT. Do not try to use CAT enabled PTT operation as its too slow.

There are the download links to Winlink and Vara HF as well.

I have also successfully used Winlink and VARA FM modem over 2m using my Flex-5000 and the FM data mode.
