A bit early in the game to build a list but here goes... -THE DSP NR WORKS...amazing concept I guess. -QSK is amazing...sucked on the OII -Shift and width controls amazing compared to Pass band tuning that the OII called it. - Receive quality really appeals to my ears...OII never sounded this good. -ATU is nothing short of brilliant compared to the OII. Faster, quieter, can tune a soup can. -Metering functions such as RF out, signal strength, SWR actually mean something and have some level of detailed definition. OII, the sub S- meter was pretty good but the main was a joke due to tap point implementation. SWR readings on the OII shotty at best. Overall ...metering on the OII was pointless. -AGC is much easier to manage that it was on the OII and much more effective as well even compared to the latest FW release of the OII - Even thought the Elecraft is much smaller that the OII...the front panel packs some serious punch on functions and layout.
There is a long list of things I am liking over the OII but these are the ones that hit me first. Hate to bag on the OII but I gave it 3 years to get things worked out.
