Bert - From a purely technical / functional standpoint (i.e. numbers), and aside from current drain and bells/whistles, the K3's receiver has the edge, and I think most would agree.
The K2's receiver is superb, and I occasionally try to make it my only rig by putting the K3 aside for a few days at a time, as I prefer the K2 for its analog signal path, size, current drain, simplicity, fewer bells/whistles, through-hole design, etc. I usually last only about a day, because for some reason I prefer the sound of the K3's receiver - it just sounds "smoother," more refined, whatever that means. This could be influenced by user interface, controls, display, for all I know. Like you, I operate 100% casual CW (and an occasional QRP sprint) and it took me a while to hear the differences between the two receivers. A contester or DXer might hear the differences faster. Bottom line - yes I think the K3 receiver has the edge, but to a casual op, the differences might not jump out at you, but after a while, you might find yourself preferring it. Everything in life's a tradeoff - the K2 still wins for a lot of other reasons (see above) and its receiver is right up there among the best. I find the advantage of the K3's receiver to be not so much in the sensitivity, but in the selectivity, noise reduction and what you can do with the DSP. There's an op in my area who enjoys working DX and uses only a K2 at 5 watts to do it, and very successfully - after spending an afternoon in his shack watching and learning, I saw he could do more with a K2 at 5 W than I'll ever do with a K3 at 100. It was a humble reminder that it's more about the op, patience, persistence and the antenna. Of course you can do that too with the K3. --Andrew, NV1B On Mon, Feb 20, 2012 at 5:11 AM, Bert Craig <wa...@arrl.net> wrote: > ... > Does anybody feel that the K2's rcvr is equal to or better than that of > the K3, additional bells and whistles notwithstanding? > > Vy 73 de Bert > WA2SI > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
