(Disclaimer: I'm biased, by definition :)
The K3 also has:
- a 2nd receiver option with identical performance to the main, which
allows you to listen to two bands at once, or do diversity receive
(the 7600 has "dual-watch", but this cannot provide diversity receive
because both receivers always share one antenna)
- an internal 2-meter option (10 W output, all modes)
- much lighter weight -- less than 10 lb, vs. 22 lb (great for
portable/emergency operation, field day, DXpeditions, etc.)
- about 1/3rd as much receive-mode current drain (~1A vs. 3A)
- over 20 dB better dynamic range in most receive categories:
http://www.sherweng.com/table.html- very narrow roofing filters (as low as 200 Hz, vs. 3 kHz minimum for
the IC-7600 -- tightest you can get in the high-performance class)
- extensive support for external transverters, including up to 9
programmable bands
- very wide-range ATU (nominally 10:1, but will frequently match 20:1
or better at QRP levels)
- both VFO A and VFO B knobs
- duplicate mic and headphone jacks on rear panel (good for keeping
cables away from front of the rig)
