"KX2" musings

[J]

Obviously, there is no KX2..  But if there were a KX2, I'd like to see these
features in one (being a KX1 fan):

 

.         More bands - 80, 60 (CW allowed on 60M channels), 40, 30, 20, 17,
15, 12, 10.  The KX1 with the 3080 kit is 80/40/30/20M.

.         5 watts out using internal battery pack; more with external power
12-15V.

.         Same shape, size, controls, display, layout as the KX1.

.         Same CW-only and SSB receive

.         Same internal tuner concept, but capable of the extra bands.

.         Same paddle key, but two screws to reduce wiggle when the key is
attached.

.         CW sidetone a sinewave to allow for easier spotting.

Interesting "wish list" for a fantasy KX2, Jay.

But- I don't believe there is any way they could add all those additional
bands (with the filtering components required), plus higher output power on
internal batteries, plus an extended range auto-tuner and still fit within
the same size box. Elecraft has some great design folks, but... you'd have
to give on that size "requirement" to stand a chance of ever seeing the
others. If you admit it would take a larger box, then you are close enough
to the KX3 to not make it worth the development costs.

73,

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.
