Re: [Elecraft] K3 NR
It's remarkable how on any list for any radio, NR is the bugaboo. Everyone expects magic. There ain't no stinkin' magic. To Bill's point, it is far less effective -- to the fact of almost being unnoticable at relatively narrow CW bandwidths. Having used virtually every 3rd party box known to man in the search for nirvana, and been in on much of the use, discussion and some analysis of another high end radio's NR function, I find the K3 NR to be extremely effective on SSB and CW, when the conditions (be they band or radio settings) are right for NR to be effective, which they are not always. As for the conjuration of it all, it's just dynamic filtering, not something mystical (that is what at LMS algorithm does -- there's nothing mystical about LMS, either). Grant/NQ5T It's interesting to hear the differing opinions on this subject. While I found the NR on the O7 to be good, it wasn't exceptional. I thought the NR function attenuated the desired signal, even at the least aggressive setting. The best DSP NR I've heard came from the Omni 6+ as well as the LMS algorithm used in the W9GR DSP box. Both DSP NR occurs in these devices at the AF level, rather than I.F. Just curious, does the K3 implement a true LMS algorithm at I.F. in one of its menu-selected NR routines? Lyle? I've never been too impressed with some of the other contour optimized NR routines like that used in the FT-1KMP series.

Re: [Elecraft] Questions from a Liberal Arts Major
Five DB steps that can be on or off with a flicker fall way short for me as well, a convincing analog meter is 50% of the listening experience at this QTH. I'm trying to figure out how to hear an S_Meter, but I suppose we all listen in different ways. I'm really surprised, after happily monitoring this list in stealth mode for some time while waiting for my K3 to arrive, how much it has begun to sound from time to time like every other vendor/product list, all of which I finally retired from after tiring of these sorts of discussions. Or perhaps I just haven't yet realized how many serious problems my new K3 has :) (returning to stealth mode) Grant/NQ5T UR RST 5 8.39974 9 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 2091 -- alive and well
I know I'm preaching to the choir here. But the ease of assembly and setup, and (at least my initial take on) performance is just outstanding. I thought at first that I would have a terrible time with the one-item- at-a-time menu system, or even even a bit of a problem with the size and control spacing. Not so on either count. Having moved to the K3 after abandoning a couple of versions of another high-end radio, I couldn't be happier. I need to start saving some shekels to add the KRX3 and another filter set. No, it doesn't have the audio heft on AM of an R-390 or SP-600, but I think I can live with that. Maybe it won't be long until the SAM detector shows up -- or the push-pull 6V6 output stage arrives as an option :) In the mean time, it's time to drag the Begali back off the shelf, and work some CW .

[Elecraft] Q re Missing K3 Kit part
I'm missing one lousy part -- a 5/8 nylon standoff that gets mounted on the DSP board (assembly errata E-7, item 3) to provide some spacing from the front panel board. While I wait for Elecraft to see my email on Monday and send the part, anyone know if this is a show stopper, or if I can proceed and come back around and install this after the fact? Thanks ...

Re: [Elecraft] Q re Missing K3 Kit part
Thanks. After looking more closely, I realized that the standoff just provides extra stiffening at the connector. I found a hex nylon standoff in my junk box, that works perfectly. It's was threaded 6-32, but it's a snug enough fit without being screwed in place once the DSP board is mounted. Onward and upward .. :) Grant/NQ5T On Nov 8, 2008, at 2:00 PM, Jeff Wandling W7BRS wrote: It's not a show stopper. It just helps you provide a little extra pressure as you push the FP to the RF board. It's nylon, it doesn't make a connection so there's no apparent impact to the circuit. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] N6XI NAQP RTTY July, 2007 with K3
I'd much prefer to have this sort of thing external to the rig and just use them to KEY the dedicated input on the rig. Couldn't agree more. I think this stuff is made integral, even if barely usable in any other than a lets see if this really works mode, to get the blood heated up, feed the hype, and little else. It's pointless and generally exceptionally poor in performance compared to a simple PC and external software option, which virtually anyone owning the radio has access to for essentially no money. But you can tell from this thread (and old threads on the 7800 list for example), that this sort of think is seen as a wow factor, even if it turns out in the end to be little more than artificial flavor in the icing. I don't know why the developers waste their time, other than at the behest of the marketing department.

RE: [Elecraft] K3: elaborate on the DSP at AF
Bandpass filters, for example, operate at IF and at AF. It would be tedious to list which functions occur at IF and which at AF, and some may change with future firmweare releases. But, it is very important important in at least two areas -- notch (auto and manual) and noise reduction. There is a substantive difference in performance and effectiveness depending on whether these functions are inside the AGC loop at IF or if they're done after the fact at AF. That would be good information to have . Thanks .. Grant/NQ5T ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
