About Us

Multus SDR, LLC designs, builds, and supports software-defined HF radios and the accessories that go with them.

This shop is for people who like building their own shack. The line runs from small accessories up to stand-alone transceivers, including the Proficio MKII and the Ultimus. A build service is available for most products if you would rather have it assembled.

Questions, schematics, and assembly notes are on the groups.io list: https://multussdr.groups.io/g/main
