Spotted a very interesting post from Tobias, DH1TW on his blog ‘Contesting & SDR‘ titled Does SDR really suck?. He wonders out loud if the performance, flexibility and cost of SDR is so excellent, why hasn’t it taken off? What possible barriers might there still be to it assuming a place matching its promise and achievement?
He identifies the missing link as adequate user interface. He mounts a case arguing for a similar level of investigation and development on the user experience front to match the investment and experimentation on RF and signal processing.
And he acknowledges that there may be more than one user interface solution. Contesting and HFPack have different UX demands as other experts understand. Look at Elecraft‘s K3 and KX1, or the Steve Weber, KD1JV designs, especially the ATS series. And now Tobias argues, SDR gives us the opportunity to re-think user interface design from the ground up.
Who says that the radio controls must be on the front of a black box and located perpendicular to your shacks desk? SDR allows us for the first time to completely redefine and optimize the radios User Interface! Are you serious into contesting? If so, you want to pay special attention to ergonomics. Why not having the control console directly next to your keyboard? Or do you prefer portable, backpack operations? Then your focus will lie on the limited physical dimensions. N2ABPs SDR-Cube is a nice example on this.
A very timely – and well illustrated – read.
