The receiver design very very badly needs a four-pole IF filter. Coverage of 15m is essential, and 17m would be nice. The ATU capability needs great improvement beyond the 254 possible reactance combos in the current model. A noise blanker would be great.
But...the most important thing: Design all of this from the start as a straight-forward system without a bunch of tricky add-on boards. Implement it with PCBs the way MFJ (yeah...I know) did their QRP Cub rigs...with most components as pre-installed SMT. Those Cub rigs were very quick to assemble and looked extremely neat...too bad the Cub RF design was so marginal. No fear of that with Elecraft.
