QDX reference on QMX web page

 

I thought this was brought up before (and fixed), but I was just showing a friend the information about the QMX and he pointed out this mistake:

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. QDX is not suitable for phase shift keyed modes such as PSK31 or modes involving multiple concurrent tones such as WinLink,

I thought I'd pass that along.
