The "QMX" (QRP Labs Multimode Xcvr): a feature-packed, high performance, five-band (80, 60, 40, 30 and 20m) 5W CW and Digi-modes transceiver kit, including embedded SDR receiver, 24-bit 48 ksps USB sound card, CAT control, synthesized VFO with TCXO reference.
QMX may be used in CW modes standalone, or with a single USB cable to a PC for digi mode operation. QMX also incorporates standalone CW, FSKCW and WSPR beacon functionality (no PC connection required).
QMX transmits a SINGLE SIGNAL on FSK signal modes, it is not an SSB modulator with associated unwanted sideband and residual carrier, or intermodulation due to amplifier non-linearity. QMX outputs a pure single signal. QMX is, in the first firmware releases, suitable only for CW and single tone FSK modes, which covers the majority of digital modes in use today. This includes everything in WSJT-X, JS8Call, some fldigi modes e.g. RTTY, Olivia and more. QMX is not suitable for phase shift keyed modes such as PSK31 or modes involving multiple concurrent tones such as WinLink,
The enclosure is black anodized extruded aluminium, very sturdy and elegant. The enclosure size is 95 x 63 x 25mm without protrusions. The front and rear panels are drilled and cut to match the QMX PCB with laser-etched lettering. The enclosure includes four self-adhesive feet and end panel securing screws.
