Getting Winlink pat, VARA, and ARDOP working on M1/M2/M3 Macs

Hi all,

I’m sure there are other modern Mac owners who would like to join the Winlink network. As part of my work with the West Middlesex ARES group here in Massachusetts, I worked out a pat configuration that is fully functional with ARDOP and VARA HF modems, despite their being Windows-only applications.

I’ve had this working for about 6 months now, and I’ve finally gotten around to writing the instructions necessary for others to try out. They are in a blog post on my web site at:

It’s also the most recent blog post on my ham radio site,

A caveat: Before folks get too excited, this does involve a piece of payware software called Crossover, which is a commercial version of WINE. It’s available from and costs $74, but it is available as a 14-day evaluation for you to see if it’s worth paying the money. I suspect that it is now possible to make this work with the open source version of WINE, but 1) I haven’t done that, and 2) I’m happy to pay the Codeweaver folks who make running Windows stuff on Macs easier.

I’ve made this configuration work with both an Icom IC-7100 and a Flexradio 6600, so I’m pretty certain it’s adaptable to most modern radios with a USB audio and CAT interface.

I hope hams using modern Macs find this useful.
