The “QDX” (QRP Labs Digital Xcvr): a feature-packed, high performance, five-band (80, 60, 40, 30, 20m) 5W Digi-modes transceiver kit, including embedded SDR receiver, 24-bit 48 ksps USB sound card, CAT control, synthesized VFO with TCXO reference. QDX transmits a SINGLE SIGNAL, it is not an SSB modulator with associated unwanted sideband and residual carrier, or intermodulation due to amplifier non-linearity. QDX outputs a pure single signal. Also available as a 20, 17, 15, 12, 11 and 10m version which produces a little lower output power around 3.5 to 4 Watts at 10m. Many thanks to Ross VK1UN for extensive tireless assistance in the filter design and experiment for the high bands version. QDX is suitable only for 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 on/off keyed modes such as CW because it does not have click-reducing RF envelope shaping; furthermore it is not suitable for phase shift keyed modes such as PSK31 or modes involving multiple concurrent tones such as WinLink. https://youtu.be/j6Vnh8eiEpg There is a good video called “JS8Call Overview and Settings 2021” at https://youtu.be/Fu0BZqTRPXQ
