QRP Labs QMX SSB beta firmware relased (qrp-labs.com)
This is the beta release page for the SSB firmware for QMX/QMX+ transceivers. This is a very complex project. The beta release here is provided without warranty, for brave beta testers who wish to try out the firmware and report back on any issues found or suggested enhancements. The firmware runs on both QMX and QMX+; for convenience from now on, this page will state "QMX" but that means equivalently QMX or QMX+ unless otherwise stated.
