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

Re: [Elecraft] K3: Any gain with a new synth?

Thank you for all the answers - here and email. I appreciate the candidness. Unfortunately, for Elecraft, I have decided to keep my K3 as it is. In my instance, I don't see enough potential improvement to justify the expense and labor (considerable to get the rig to the bench and back). I

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

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

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 >

Re: [Elecraft] K3: Any gain with a new synth?

I have my "old K3" on QTH.com, priced at what it would take to get it. Meanwhile it is still on my operating desk and if no one wants it, then it will stay right here, hooked up and ready to roll. Who knows I might try satellite again and a second K3 so I can run full duplex with my K3s works

Re: [Elecraft] K3: Any gain with a new synth?

I have 2K3s and the new K3S.  The noise reduction function much better on K3S 73dsGeorge, WGF On Sunday, September 6, 2015 8:35 AM, Jim Rogers wrote: I have my "old K3" on QTH.com, priced at what it would take to get it. Meanwhile it is still on my operating

Re: [Elecraft] K3: Any gain with a new synth?

I have two K3s and now a new K3S.  I not sure the sync card makes much difference, but the noise reduction is now outstanding. George, W6GF PS: A great radio was made greater On Saturday, September 5, 2015 9:39 AM, Phil Wheeler wrote: Bob, I noticed an

Re: [Elecraft] K3: Any gain with a new synth?

Bob, I noticed an improvement right away just by tuning 20 CW during a very active contest weekend. My ability to pull out weak signals was much enhanced. But I do agree completely with you for Bill's purposes "I don't contest or DX - just rag chew on 160/75/40... ". 73, Phil W7OX On

Re: [Elecraft] K3: Any gain with a new synth?

Bill, I upgraded the synth and have not noticed any difference whatsoever.  That is not to say there is none, only that I could not tell any difference since I could not do any A/B comparisons. I am very skeptical of those who claim to have noticed a difference without having done an actual A/B

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

[Elecraft] K3: Any gain with a new synth?

My K3 is from early 2012 - ser: 62xx. I don't contest or DX - just rag chew on 160/75/40 - makes a super 500 Watt station. Rarely do I touch any controls other than the VFO or band switch. My QTH is very low noise - typical local daytime noise level barely registers on the P3 (think S-0).

[Elecraft] K3: Any gain with a new synth?

I consider myself a casual operator. I get on when I can, avoid the contests, rag chew a lot, and have fun. I mostly work SSB with my K3 but am working on code speed. I use WIN4K3 as a control program and panadaptor.   These differences are purely subjective and without measurement. All
