The K3 solves the latter design objectives quite well; while it's IMD is not wonderful at 100W, it's pretty good at the 25-50W level need to drive most power amps, and the real enemy of two radios in close proximity on the same band, phase noise, is spectacularly good. What matters about IMD are clicks and splatter when the signal is loudest, usually when it is driving a legal limit amp. It's a byproduct of my work in the highest levels of pro audio, where I learned not to make the lab measurements of a distortion, but to measure the practical effects of it, clicks and splatter. And modern spectrum analyzers, like the P3/SVGA and lots of SDRs with good software blow away the lab gear for these measurements by at least two orders of magnitude! The frequency resolution of my HP8590D is only 100 Hz, compared to the P3 at a few Hz and the P3SVGA 10x better! Yes, the P3 can display only 80 dB of its 100 dB dynamic range on screen, but the bodies are buried in the range of 40-70 dB down! The K3 is a spectacularly good neighbor on CW, thanks to the carefully shaped keying -- my neighbor K6XX and I, about 3 miles apart, can run legal limit to serious antennas and work within 500 Hz of each other when contesting. And thanks to the control of phase noise, our CQP team could run K3s with KPA500s on the same band with in-line dipoles and Yagis from 80-10M. At home, I learned that could run two K3s and Ten Tec legal limit 3CX800A7 amps on the SAME BAND, 20M and above, within 60 kHz of each other, feeding Yagis separated by 100 ft, colinear to each other, and not know the other transmitter was there! There is FAR more to life than measurements of IMD test signals! A FAR better test of IMD is the measurement of the bandwidth of a signal using spectrum analysis capable of very narrow resolution bandwidth, like the P3 (a few Hz), or even better, the P3/SVGA (a few fractional Hz). Download and study http://k9yc.com/P3_Spectrum_Measurements.pdf and http://k9yc.com/TXNoise.pdf The first link shows measurements of my K3, pre-upgraded synths, driving a Ten Tec 425 (2 3CX800A7s), a KPA500, and another amp I sold as soon as I realized how dirty it was compared to the others. The second link is my analysis data ARRL Labs sent me in electronic form of their measurements of more than a dozen rigs, plotting all on the same graph making comparison jump out at you! It was motivated by complaints by WRTC participants of trash competitors in the same group of sites were generating with rigs like the FTDX1000. BTW -- after I'd done the work for the first link, Warren Pratt, NR0V, inventor of Pure Signal and long-time running partner of Rob Sherwood, NC0B, demonstrated to me that the RX in the $900 ANAN transceiver could display fractional Hz resolution with 120 dB dynamic range with his software (for ANAN) running the radio. I bought one to use in my measurement lab!

Re: [Elecraft] Field Day Operation
Dave, et al, The K3s is one of several 1.8 to 54MHz transceivers that has suffered the consequences of using VMOS FETs in their final amplifiers. And some, even if tuned as well as possible to minimize splatter, will not be considered friendly neighbors on the congested bands of today.

Re: [Elecraft] Field Day Operation
Which begs the question(s), "Why would one engineer a radio that can be 'misadjusted' to create awful signals?" Adjustable keying rise/fall times comes to mind first I guess since there is one optimal shape and rise/fall times. All others are sub-optimal.

Re: [Elecraft] Field Day Operation
Yes, as I understood it, the Icom rise time default is a BAD choice, but recent (e.g. IC7300 and others) radios permitted changing this to a better value, although still behind the cleaner output of Elecraft & Kenwood. The other interesting part of the discussion was the use of “pre distortion”. Again I read this as a way for the exciting transmitter to compensate for non-linearity (and resulting dirty emissions) introduced by a modern semiconductor based “linear” amplifier (one place where tubes excel). All new and interesting stuff to me - and apparently the driving force behind the ARRL “Clean Signal Initiative” to both define better standards, then rate transmitters in ARRL testing against these standards. And of course, encourage/coerce manufacturers to clean up their outputs!

Re: [Elecraft] Field Day Operation
There are some things in a transmitter that just should never be adjustable. There is an optimum rise time and waveshape for minimizing clicks. It is what it is, it's the best you can get, and there is no reason whatsoever to change it. Nearly a lifetime ago at a college ham station, there was a very large bright red button on the amplifier rack labeled "Do Not Press." Most every visitor did and discovered that nothing happened ... until they let go ... at which point a loud fire bell sounded. It could be silenced by pressing and holding the button. Give someone a knob and they will turn it. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County Steve L wrote on 7/1/2023 10:34 AM: George, The IC7300 was among the better commercial transceivers in terms of spurious emissions, clicks, splatter, etc. It wasn’t at the top of the list (the K3s is however), but was in the “better” category.

It's good to see that Rob has finally started paying attention to dirty transmit, but I started working on this ten years ago. My first publication was jointly with K6XX, the second an analysis of ARRL Labs data that they sent me in electronic form. The third consists of measurements in my own lab, using the P3/SVGA in my second radio. http://k9yc.com/K6XXAmpTalk.pdf (Published Nov 2013) http://k9yc.com/TXNoise.pdf (published July 2014) http://k9yc.com/P3_Spectrum_Measurements.pdf (published March 2015) When I leaked an early version of the ARRL data analysis to someone I strongly suspected would make sure that Yaesu saw it, they issued a firmware update that brought their flagship radio, the FTDX5000 from absolute worst to roughly even with the second worst, ICOM 7800. The March 2015 shows before and after measurements of a neighbor's Yaesu rig. While Rob is a great engineer and has done a lot to improve our receivers, there are some things he doesn't understand, and refuses to listen to what I've told him to fill in his gaps -- that audio is dynamic, and that traditional RF test signals are not the way to test SSB rigs. Rather pink noise, which has been used in pro audio for more than 40 years, is a far better test signal to expose defects in rigs, an example of which is, again, Yaesu! 73, Jim K9YC 73, Jim K9YC __ 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] Field Day Operation
Thanks, I just extracted that period from my log (DXBase) to take another look after all of these years. I operated only 20-meter SSB and took a break from 0718Z to 1347Z. There were a lot of two QSO/minutes and some three QSOs/min. So it's more like 88 Qs/hr :-) This predates my K3, so I was using a TS-870 and HB 3-el Yagi@45 feet.

He (and the others) shoulda known better. The only reason I continue to operate SSB on Field Day is because my two sons operate with me and, since they don't know CW, this allows them to participate with me, which so far has made it worth putting up with the circumstances I complain about.

Re: [Elecraft] Field Day Operation
I don't understand the knock on SSB. (I'm a few away from Honor Roll on CW so I do that mode too). I haven't operated FD for years, since I've outlived the guys I used to mountain top with and it's to damn hot here in the valley to be in the field. (107F as I write). But looking back some years I operated either 1E or 1D and single-handedly worked 1040 Qs in 2001, 1357 in 2004, 1532 in 2005, 1093 in 2007 and slowed down to 1075 in 2009. All on SSB and 100W. With a regular logging program and no voice recording. You simply have to be nice to the inexperience operators and coach them along. I never have understood the contestor types who get so wound up, frantic and rude. My 2 cents.

I made almost 400 CW QSOs, K3 and 80m dipole/window line/MFJ tuner. I had a 98% success when calling and many replies, often multiples, when running. There were MANY strong signals on 40 and 20 at all hours I was on, so I didn't do 80. Almost all CW was good, partly thanks to computer keying, and I encountered maybe three poor ops, not rude, just inexperienced/unpracticed. I like SK and used it about 30% of the time.

Re: [Elecraft] Field Day Operation
Wayne, I suspect that after the software becomes more stable, and more folks use the K4, it will replace the K3 for DX operations... The question now becomes, will it fit in a RIB setup.

Re: [Elecraft] Field Day Operation
I used a kx1, operating FD with emergency power (batteries internal to kx1). I used two sets of batteries. The maximum output was 1.5 watts but after 2.5 hours of operating power output dropped to .5 watts. So, I used another set of fresh batteries to operate a total of 5.5 hours. I made 70 contacts on 20m and 59 on 40m. Of course I have large antennas. However, I was surprised by how well the receiver did using my home-station antennas (yagis)! Dynamic range was not an issue but there was some I-F "blowby," on very strong signals but many dB down from other signals. ...amazing performance for such a simple radio. 73.
