Re: [Elecraft] K3: Any gain with a new synth?
That’s interesting. The K3 and K3S use the same DSP algorithm (same firmware) to accomplish NR. In what way do you perceive it being different? Are the settings (AGC threshold, etc) the same on the all of the radios? Grant NQ5T > On Sep 6, 2015, at 11:28 AM, george fritkin via Elecraft > wrote: > > I have 2K3s and the new K3S.

Re: [Elecraft] K3: Any gain with a new synth?
George, Just to confirm -- you are referring to the Noise Reduction function that is evoked by pressing the "NR" button; correct? If so, why should it be ANY different at all from that of the K3, given the same firmware revision level, in which case I would assume the exact same algorithm is in place for both radios? 73, Dale WA8SRA > I have 2K3s and the new K3S.

Re: [Elecraft] K3: Any gain with a new synth?
That’s kind of what I’ve been thinking too, Bill. With my often high noise level suburban location combined with modest wire and vertical antennas I think it would be overkill and not worth the investment. As it is I often joke that the K3 for me like driving a McLaren to the grocery store-way more than I need. That said I’m not parting with it ! Thanks Elecraft for at least giving us the upgrade option. 73, Brian K3USC (since 1962) > On Sep 6, 2015, at 9:16 AM, Bill wrote: > > Thank you for all the answers - here and email.

Re: [Elecraft] K3: Any gain with a new synth?
Bill: I just finished installing the new boards in both my K3's. I did one radio complete and then did a quick test on 80m and 20m with both radios. I found the new boards quiets the receiver down somewhat and makes it easier to pull out the weaker signals. I have pretty quiet conditions at my QTH, all utilities are underground. My simple test was comparing Rig A (New KSYN3A boards installed) to Rig B (Old KSYN3 boards installed). I have not done any real tests to further evaluate the new boards, but in my case they have helped somewhat Maybe the new boards do really help, or perhaps it was me sub consciously wanting to believe that to justify the cost. 73 De Mike VE3YF http://www.ve3yf.com __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] K3: Any gain with a new synth?
NK7Z has some A/B comparisons that show some improvement and I thought I heard the same differences during a contest. However, I bet you won't see that much difference using LSB on the lower bands. I am quite jealous of your noise levels. On Sat, 5 Sep 2015, Phil Wheeler wrote: Bob, I noticed an improvement right away just by tuning 20 CW during a very active contest weekend.
