[Elecraft] K3: Thinking return to K3.

[Wayne Burdick]

(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:

- 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)
