Hi Johnny,
I can refine your points a bit further, in relation to the KX3:

With the KXFL3 module installed, the KX3 has IMDDR3 in the ~100 dB
range at 2 kHz and blocking DR in the 140 dB range.
> 2. Current drain of K2 is as low as 180 ma;
KX3: as low as 140 mA.
> 3. Built-in ATU of K2 (swr 10:1) is convenient;
Both the KXAT3 and KAT2 will actually match 20:1 or higher in many
cases.
> 4. Built-in speech processor of K2 gives much more talk power;
KX3: 32-bit floating-point DSP => split-band speech processing, TX EQ,
2 DVR messages, etc.
> 5. K2 can deliver more power at 10-15W;
KX3: Max 12 W (5 W typical from internal batteries).
> 6. The V/U operation of FT817 can be covered by H/T
KX3: 2-meter module in the works.
