The QDX is about the size of a pack of cards i.e. tiny.
Also, I am having issues booting up my QMX+ rig today. It keeps coming up with a dim display and not initialising.
Without the SignaLink interface or QMX+ I am unable to use FT8 at 8m or 6m, which is a pity. I suppose I could use the IC705 at 6m for FT8. At present I was using the QMX+ for 6m and the FT817ND (dealer modified) for 8m.
