QMX in Digi mode transmits a SINGLE SIGNAL, 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. Digi mode is suitable for single tone FSK modes, which covers the majority of digital modes in use today This includes everything in WSJT-X (except MSK144), JS8Call, some fldigi modes e.g. RTTY, Olivia and more. QMX is also suitable for on/off keyed modes such as CW because it has click-reducing RF envelope shaping. For phase shift keyed modes such as PSK31 or modes involving multiple concurrent tones such as VARA WinLink, SSB (USB) mode should be used.

Assembled kit: The kit will be by default, assembled for operation from a 12V supply. If you prefer it to be built for 9V supply operation, please write a note in the customer notes/comments field at the checkout. NOTE: Assembled kits are built to order, the waiting list is published here https://www.qrp-labs.com/qcxmini/assembled.html - we ship around 50 per week so, if you are ordering an Assembled radio, please accept some waiting time based on this; if you need it urgently then please contact us about it.

The Optional enclosure is black anodized extruded aluminium, very sturdy and elegant. The enclosure size is 92 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.
