Re: [Elecraft] K3 - Should I buy simple now or save for loaded rig?

How difficult is it to keep adding modules on? I would be buying the kit form. Not difficult at all. The only tricky part about building a fully loaded K3 is that the sub-RX is a real shoe-horn job, and you have to remove it to add stuff to either it or the main board, even filters. Thus, I would suggest that you make it the last thing you add. Everything else is a piece of cake. Another alternative. The KX3 is a real nice radio. For about the price of a not-loaded K3 you could add a KPA500 to it and have a 250W radio. It all depends on what you want to do with it when you're done. :) Later, buy the K3 with the KAT500 high power antenna tuner, drive the amp with that, and you've got a real nice 600W station. 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
[Elecraft] Operating from a Hotel
Horrid electrical noise in hotels because of air conditioners. I stayed in a hotel in Redmond, WA. I tried using my KS3 with a 28' wire extending out from the window and a 16' counterpoise which was inside the hotel room. I was not able to receive anything on any band. All I heard was massive electrical noise at above S 20-40. I believe that this electrical noise was generated by variable speed motors in the air conditioning units. Has anyone experienced this? Any suggestions or solutions?

Re: [Elecraft] Operating from a Hotel
Use a coax-fed antenna as far away as possible, even on the roof. Add a choke to reduce noise pick-up on the coax. Your 'counterpoise' is part of the aerial and picks up from its environment as it's bound to do. 73 David G3UNA Horrid electrical noise in hotels because of air conditioners.

[Elecraft] [T1]
Ian, I would stay away from the Elecraft T1 tuner. It is too small, the tuning range is too large, its power consumption is way too low, the leds are too easy to understand, it is too easy to use--DO NOT order the 817 cable that automagically remembers band settings--and it is way too well built even if you build it yourself. It lacks air inside the case, compared to all other tuners on the market. The 9-volt batteries to power it are available at far too many places, and you don't have to replace them nearly often enough. You've been warned. 73, Eric WD6DBM I am to the point of contemplating tuners to go with my FT-817 and (probably) 20m half-wave OCF dipole antenna. Has anyone used the Elecraft T1 QRP tuner? Can anyone speak intelligently to the (de)merits of the device? It gets really great reviews on eHam, but I tend to be overly cautious of eHam reviews. I'm interested in the opinions of trusted sources before I plunk down the green for the kit.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks

Re: [Elecraft] [XG3} Experiences and Opinions?
Bob, The XG3 is quite a capable signal generator. It can do a lot, especially when used with the XG3 Utility program, and sounds like it would be excellent for the purposes you have stated. It is quite stable both frequency wise and output level wise. Drawbacks of the XG3 as I see it is that one cannot simply add an attenuator to obtain extremely low signal levels (for true MDS measurements), the XG3 is not shielded. The only other downside is that it has a square wave output. That is not normally a problem because you would inject the signal into the tuned circuits of a receiver front end, and those tuned circuits turn the waveform into a nice sine wave. 73, Don W3FPR On 9/13/2012 8:13 AM, Bob Molloy wrote: Hi, As I slowly expand my knowledge in homebrewing, I've decided an XG3 should be my next piece of test equipment (after a DMM and a Rigol DS1102E 'scope).

Re: [Elecraft] KX3-MIC COMP Setting / Metering
Well, Mostly because Gary at Elecraft told me he monitors power output since the ALC meter isn't driving right and that is what he recommends. That is difficult in the field on batteries because the target power is variable based on voltage. Also, the meter defaults to ALC when adjusting mic gain making it hard to see power while adjusting since this can't be overriden. I'm also concerned about having a dirty, overmodulated signal, so I'm staying conservative. As near as I can tell, I may be okay with a setting as low as 10-12, and 1 on compression but others are saying they are driving with as much gain as 40+ and significanltly higher compression. This seems to be a pretty broad range for everyone with identical equipment to be properly adjusted (understanding minor differences may occur with different voice characteristics) I haven't had a chance to coordinate a contact with a local friend and I have difficulty listening to my own voice in a second receiver. -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-MIC-COMP-Setting-Metering-tp7562532p7562590.html Sent from the Elecraft mailing list archive at Nabble.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

Re: [Elecraft] Operating from a Hotel
If the hotel has a balcony, I have used a MFJ fiberglass extending pole in the past which suspended a resonant fan dipole and an rfi filter in line and it worked well. I tried one of those mini antenna verticals by Super Antenna and it did not perform well from balcony. With a resonant dipole in 20m and 15m I was able to work a lot of DX. The owner of the hotel was cool about the antenna but eventually I decided to outfit my mobile (work in progress) and drive up to the highest points in Malibu instead. I am fortunate that my current consutling engagement is driving distance from home. Today I was able to work KH8S on 40m with a badly tuned hamstick (my turbo tuner and Hi Q are giving me fits at the moment) and 10W (top of Kanan road in Malibu). I agree that it is better to get out of the hotel and do what you can in the outdoor environs.

I use a small electret mike form an old computer. Mic gain of 6 causes ALC activity just below full scale. Reports indicated that COMP to the max (30) produced punchy and undistorted signal. When listening on K3, varying mic gain from 4 to 10 caused very little difference in speech quality. IM in KX3 strongly depends on the combination of power and voltage. See a document in file section on yahoo KX3 site. Too much power at low voltage can cause IMD of -20db. The effect of mic gain and compression on IMD is much lower than that of voltage. Confirmed on P3. KX3 seems to be very sensitive to low voltage as far as efficiency is concerned. For example, at 12V the radio draws 2.2A and produces 10W. About 38% efficiency and 16W dissipation. At 8V (NiMH under load), the radio produces 2.5W and draws 1.8A, for 17% efficiency and 12 W dissipation. Voltage and amp readings from KX3. Setting power to 5W at 12V, the radio draws 1.1A, for 38% efficiency and 8 W dissipation. Not all of it is bad as many other radios stop working 11V.

The issue I was having with the BAND CHANGE parameter has been resolved with KPA500 test load V1.16. __ Hi Jack... Thanks for the reply. Yes, RADIO has been set to BCD since I put the AMP online today. The band changes just fine under the control of the FT-950, so the amp is getting the correct info. I checked to make sure the amp changed with each band selected on the FT-950. It's just when I change bands, the amp will not go from OPER to STBY automatically with the BAND CHANGE parameter set to STBY. The amp is serial number 1041 and the firmware is 1.11 from August 21, 2012. It would be nice for the amp to go to STBY, so I can make sure the auto-tuner is good to go.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
I also had this problem recently: I was using my K3 in the vicinity of several other operators who were using an IC-706MkIIG, an FT-857D, and an IC-7000. All of these other radios produced horrible in-band phase noise. When I asked them about it, they were completely unaware that I was on the band! The other stations were at least 100 meters away and using opposite polarization from me on 20 meters. The noise floor increased from S0 to S3-S4 with the 706 and 857, which were farther away and S0 to S7ish with the 7000 which was much closer. Of course, this was one of the many selling points of the K3 for me. I guess the K2 is also very clean on TX phase noise? 73, --Ethan, K8GU/4.

This driver will *not* automatically install when the 0204 card is first plugged in, but is easily installed from Device Manager via the Update Driver utility.

This driver is dated 11-12-2010 and is version 6.6.1.1 by Creative Labs. Follow Larry's instructions for defaulting the sample rate to 192 K in Windows mixer setup and set the output to something other than the EMU 0204 in NaP3 setup and it should work well. Bill, WA4KBD -- FYI to all reading this thread: The 4GB RAM issue only appears to affect playback. The problem is that the audio will break up/lose sync after a period of time. This only applies, of course, if you actually listen to the output of the SDR. If you select another sound card in the Output selection in NaP3, it will be fine. You really don't need 192kHz for playback, since the widest filter is 10kHz. So any sound card will do just fine, including a built in one. You can still select the E-MU for Input and use 192kHz sampling for input. Therefore, you don't need to give up your extra RAM.

Also interesting is that originally when selecting CODEC, it showed 02-mK CODEC and 05-mk CODEC but after selected CSB then reverting to CODEC, it now numbers them 01-mk CODEC and 04-mK CODECany significance to that? Ok, so setup the JT65-HF for CSB in/out and on the mK II, selected CSB under tab Audio MixerI get the tones when software sends, the rig is keyed, but no power output. While in this config, i.e., CSB on mK II, went to Audio Mixer tab and selected 'Test signal', I get the toneWhen I select mK CODEC on same tab...no tone when selecting Test Signal ??? If I go to the K3 DATA A and change to AFSK, then 'Test Signal', no tone. However if I select either FSK or PSK-D on the K3, I get the appropriate 'Test Signal on the mK II. So, I do not know why the CODEC is not producing tones for DATA A or AFSK...Joe?

But it doesn't turn it back to the center when it stops. This will happen every time you're using N1MM. I suspect other contest loggers do the same. Also, either Windoze, or other Windoze programs may be manipulating the Playback Mixer. Playback Mixer LEVELS may also be the problem. JT65-HF, and other digital software, uses the WAV input to the mixer, so look at its level, and also at the MASTER level control. Neither should be all the way up or all the way down, both should be something like 2/3 up. The thing I'm puzzling about is that you say you're using VOX and it's going into transmit, which means you're getting audio into the radio. OR -- are you using BOTH VOX and PTT? Try VOX ONLY, and see if the radio transmits. If it does, it's getting audio. Another idea -- for a test, plug headphones into the computer headphone jack and see if you hear the JT65 tones when the software is sending. 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

Re: [Elecraft] [XG3} Experiences and Opinions?
Bob, The XG3 is quite a capable signal generator. It can do a lot, especially when used with the XG3 Utility program, and sounds like it would be excellent for the purposes you have stated. It is quite stable both frequency wise and output level wise. Drawbacks of the XG3 as I see it is that one cannot simply add an attenuator to obtain extremely low signal levels (for true MDS measurements), the XG3 is not shielded. The only other downside is that it has a square wave output. That is not normally a problem because you would inject the signal into the tuned circuits of a receiver front end, and those tuned circuits turn the waveform into a nice sine wave. 73, Don W3FPR Bob and Don, I use my XG3 frequently and mostly to check health of my receivers on freq up to 1296. Above 200-MHz the output is a harmonic so output is not calibrated. I think typically output follows (1/n)^2 rule (inverse square of harmonic multiplier) e,g, 432 is -9 dB since XG3 runs at 144 and uses 3rd harmonic. On freq. up thru 200-MHz I find 0 dBm level calib is within 1-dB as measured on my HP microwave power meter. Checking -33 and -73 test levels against 0 dBm into attenuators is very close. -107 dBm suffers some leakage so use of a shielded enclosure is needed (I use a Hammond 1550 diecast box with BNC bulkhead adapter). With use of the box I can add attenuation down to about -145 dBm with no leakage. If I use double-shielded coax I can go to -155 dBm That is eme quality receiver sensitivity on 144. I have even used my XG3 for testing VHF transverters by running 0 dBm at 28-MHz into the transverter in place of IF radio drive. Square wave doesn't present a problem for most testing. Total power out of XG3 200-MHz is the fundamental plus harmonics so may be an issue if tuning circuits that can pass both frequencies. I bought several 7-pole LP filters from CoilCraft to filter all harmonics of the suqare wave when a pure sine wave is needed. Only shortcoming is testing FM radios as there is no provision for modulating the carrier signal. But you can observe quieting of the FM radio with a test signal. 73, Ed - KL7uW __ 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

( http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=310401470794ssPag eName=ADME:L:OU:US:3160 ) First, it IS stereo in and stereo out. There is some confusing wording even on the packaging but it is indeed stereo all around. Someone suggested that the chip MAY not be as advertised. As this IS from China (with a Taiwanese chip) and having dealt with Asia for decades, I opened it (not recommended for the inexperienced, it is glued shut). It is indeed the Via Vinyl Envy USB VT-1620A chip ( http://www.via.com.tw/en/products/audio/usb/vt1620a/index.jsp ). The Via driver from their web site loaded and recognized the chip so I am 100% sure it is genuine. It should be capable of: a.. 2-channel ADC with 90dB SNR, 16/24-bit supporting 44.1/48/96/192kHz sample rates a.. 2-channel DAC with 95dB SNR, 16/24-bit supporting 44.1/48/96/192kHz sample rates I have some photos if anyone is interested. It is a nice little board and looks to be well made. Both the input (Mic) and output (Headphones and SPDIF optical) are standard 1/8 stereo jacks with the output having the additional optical coupler mounted just past the electrical contacts. It works great with HRD but I have no way of testing it for I/Q use as my KX3 is still a dream and my K3 is not equipped for I/Q out. Maybe someone better equipped and more knowledgeable could put this little guy through some tests??? If so contact me. FYI my QTH is Watsonville. BTW, I have no financial interest in this at all.

[Elecraft] [KX3] Antenna Tuner Or Not
I am perplexed and bewildered but not yet bothered. I can't decide on whether I should order the internal 20 watt ATU or not. I have the external T1 ATU and can use that but I would buy the internal ATU if there were significant advantages like ease of use. I plan to use the KX3 in both a portable fashion and mobile in my truck. I will use as mobile with my Hi-Q screwdriver that is tuned for low SWR via an external drive tuner (like N2VZ turbo tuner) so I will not really need an ATU. But, I am not going mobile until the 100-watt amp is available. With portable work, I will be barefoot with the KX3. I use the T1 now with my KX1.

I must admit it took a little fiddling to become stable, but it does work. The only problem that still remains is when I do a lot of fast tuning of my KX3 using NaP3, the system becomes unstable and crashes, but otherwise, it works FB. I should also tell you that I have VAC installed and am using FLDIGI for PSK31. I use my laptop's sound card for that step. This combination seems quite stable, so far. So, don't give up yet.

You really don't need 192kHz for playback, since the widest filter is 10kHz. So any sound card will do just fine, including a built in one.

Re: [Elecraft] K3: external VFO control (for EME)
I have final information for making the K3 work with MAP65v2 for those who are interested in working eme with their K3. Trakbox: http://www.qsl.net/ik7ezn/Trakbox.htm will send transmit frequency to the K3 via RS232 jack. Trakbox reads azel.dat file produced by MAP65 to determine the frequency to operate (it can also point antennas). Trakbox is fairly simple to setup, however is needs a dedicated RS232 line from the computer to the K3. Since MAP65 also requires connection to the K3 serial port using RTS control lines to control PTT this presents a problem (but solvable). Solution one: build a PTT interface for the K3 using a 2n and 1K resistor on the base which is connected to the computer RS232 line pin7 and gnd to pin4. Set com-port on MAP65 to control this line. Set Trakbox com-port for a separate RS232 line to the K3 serial jack. The 2N shorts the PTT jack on the K3. One can substitute an NPN opto-isolator transistor if you wish to isolate computer grounds from the K3. Solution two: Make a small box with two DB9 RS232 jacks to connect to two separate com ports on the computer. Connect pins 2 and 3 of the cable that connects Trakbox to same pins on a third RS232 jack that will connect to the K3. Connect pins 7 and 4 from the second jack connected to the other com-port controlled by MAP65 to the same pins on the third RS232 jack that connects to the K3. This way two com-ports can simultaneously connect to the serial port on the K3 and requires no other interfacing. Essentially a custom wye connection box. USB/RS232 conversion cables can be used between the computer ports and the box if the computer has no RS232 jacks. Two cables required. I received my first eme signal using MAP65 this morning. I have to make up a box for solution-two before I have MAP65 fully interfaced for controlling the K3. I plan to use my KX3 USB/RS232 cable for the second cable until I can purchase a dedicated cable.

Also it will match it to a lower SWR than an LDG tuner. The measurements indicate that the tuning ranges internal to the K2, K3 and KX3 are all superior. At least that is what all the numbers say.

Phil, As you note, there are several factors to think about. However, one thing that I always consider when choosing options is resale value. You may love your KX3 forever and it may be part of your estate sale. On the other hand, some day you may want to sell it to finance the purchase of a KX4 or other goody.

Re: [Elecraft] [KX3] Antenna Tuner Or Not
Phil, I only use non-resonant wire antennas fed with ladder line through baluns (4:1 and 9:1). The K3 ATU (and I think Wayne said that the KX3 transmatch had essentially the same design philosophy) handles the 160M full-size delta loop on top band through 6M, and the 80M dipole on 80M through 6M, without flinching. The challenges to the transmatch are pretty severe some times, especially during rain and snow, but the *Tuner* handles it with ease. [With experience, I can now judge the rate of precipitation by the amount of touching up required by the transmatch (seriously)]. While I didn't much like it and I doubt that it was very efficient, I found one of my friends operating my K3 using the 80M dipole loaded on 160M with apparent ease so far as matching was concerned. I assume that the ladder line became part of the radiating portion of the antenna in this particular case. The other advantages, of course, are the nice integration of the Elecraft ATU with the radio, plus if you take the radio into the field a lot like I do, it's one box and a couple of cables fewer to concern yourself with. If one has the option, buying the radio and the matching device from the same source (that would be Elecraft) makes a lot of practical sense. During tuning, the K3 ATU I also very quiet compared with another transmatch I once owned. 73, Gary VE1RGB -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Phil Hystad Sent: September 13, 2012 3:13 PM To: Elecraft List Subject: [Elecraft] [KX3] Antenna Tuner Or Not I am perplexed and bewildered but not yet bothered.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
Although the dominant competitive specs these days are receiver measurements, the cleanliness of the K3 should get more press. It is perhaps a tough moral sell but drop-dead easy in the multi-TX market. And Field Day is the most popular activity in US ham radio. In addition to enhancing K3 sales, more awareness should also stimulate Elecraft's competition, perhaps some day making a big improvement in inter-station interference everywhere. There may even be a viable argument that Elecraft has advanced the state of the art enough that eventual tightening of regulatory spectral purity standards for new rigs will be merited. Some may balk at that, but note that we are no longer allowed to operate spark, much to everyone's satisfaction.

As Wayne pointed out, phase noise may limit receiver sensitivity (if it's not limited first by other factors), but most hams have never thought about it that way. I suspect, in practice, that in other transceivers phase noise is not the limiting factor in sensitivity - mainly because the front end design is shoddy compared to the K3. Front end noise figure is perhaps a larger factor in many cases. The main real-world problem is that the K3 is a minority in the general ham rig population. Maybe someday, the K3 penetration rate will be high enough that we can hear it in how quiet the bands are. Crowded but quiet between signals that is. __ 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
Re: [Elecraft] [KX3] Antenna Tuner Or Not
Gary and all the others who responded to my question (on and off the net)... Thanks for your comments and suggestions. I have made up my mind. I will be ordering the KX3 Internal ATU with my KX3 order. I hear of a price increase -- that has not happened yet has it? Maybe I should place my order when I get home from work this afternoon. 73, phil, K7PEH PEH's iPad On Sep 13, 2012, at 12:19 PM, gary bartlett garybartl...@accesswave.ca wrote: Phil, I only use non-resonant wire antennas fed with ladder line through baluns (4:1 and 9:1). The K3 ATU (and I think Wayne said that the KX3 transmatch had essentially the same design philosophy) handles the 160M full-size delta loop on top band through 6M, and the 80M dipole on 80M through 6M, without flinching. The challenges to the transmatch are pretty severe some times, especially during rain and snow, but the *Tuner* handles it with ease. [With experience, I can now judge the rate of precipitation by the amount of touching up required by the transmatch (seriously)]. While I didn't much like it and I doubt that it was very efficient, I found one of my friends operating my K3 using the 80M dipole loaded on 160M with apparent ease so far as matching was concerned. I assume that the ladder line became part of the radiating portion of the antenna in this particular case. The other advantages, of course, are the nice integration of the Elecraft ATU with the radio, plus if you take the radio into the field a lot like I do, it's one box and a couple of cables fewer to concern yourself with. If one has the option, buying the radio and the matching device from the same source (that would be Elecraft) makes a lot of practical sense. During tuning, the K3 ATU I also very quiet compared with another transmatch I once owned. 73, Gary VE1RGB -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Phil Hystad Sent: September 13, 2012 3:13 PM To: Elecraft List Subject: [Elecraft] [KX3] Antenna Tuner Or Not I am perplexed and bewildered but not yet bothered.

Re: [Elecraft] Getting ready to order a K2 - which options
The ATU, in addition to ATUing, adds a second antenna socket. The 160/RXant option adds 160 meters and an RX antenna socket, along with the firmware to receive on the RX ant and automatically transmit on another. Some find the noise blanker to be important.

Re: [Elecraft] Getting ready to order a K2 - which options
Burke, It depends on what you want to accomplish with your K2. Yes, the KSB2 will allow you to use digital modes - the K2 also has a 3rd set of filters that can be set up called the RTTY filter set (turn it on or off in the secondary menu). The K160RX adds a receive antenna and the 160 meter band. The K60XV option adds 60 meters and a transverter interface. The KAF2 adds a peaked audio filter that is very nice for CW. The KDSP2 (which goes in the same place as the KAF2 - you can't have both) adds audio DSP to provide brick wall selectivity as well as Noise Reduction. The KNB2 works well with impulse noise (like auto ignition noise) if that is a problem at your location. The KIO2 allows you to control the K2 from a computer or use an automated logger. That is the list unless you want to consider the internal battery or the tuner or the KPA100 73, Don W3FPR On 9/13/2012 3:22 PM, Burke Jones wrote: I am getting ready to put in an order for a K2 kit.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
Hi, Agreed on both points. Others have pointed out that wideband noise on transmit is often much higher than the phase noise produced by the synthesizer. My neighbor (3 doors = 240' away) is a good example of noise produced by the transmit amplifiers rather than the synthesizer. He uses mostly CW and his IC-756 has strong wideband noise even with key up (I am sure he does nut run full QSK). The key up noise must be produced by his amplifier chain, not the synth. It of course also completely rules out noise from my synthesizer as the cause. AB2TC - Knut Alan Bloom wrote snip Assuming the same synthesizer is used for the transmitter and receiver, then phase noise should affect the receiver and transmitter equally. Those guys using transceivers with poor phase noise should also have been wiped out on receive, even though the interfering K3 was clean. I suspect the problem is broadband amplitude noise generated in the power amplifier chain. That would affect the transmitted noise but not the receiver performance.

What has been pointed out here and what Lyle said yesterday (see below) and what others have pointed out in their own ways has demystified a subject that, once couched in simple words, is not so hard to understand. Put another way, so many of the offending transceivers run the transmit IF wide open to insure sufficient drive to the final amplifiers and rely on ALC feedback to reduce the gain as necessary. This assures that the phase noise from multiple synthesizers and low level noise in the amplifiers themselves will *all* appear in the output as much as 20 dB higher than a rig like the K3 where the IF gain is properly controlled. 73, ...

Re: [Elecraft] Antenna Tuner Or Not
So, are there advantages to the internal KX3 ATU over the T1. I believe the tuning range on the internal ATU is very wide. Someone on the reflector compared the tuning ranges of all the Elecraft ATUs and it is wider than the T1. I posted such information last month, summarized now as follows: ELECRAFT ATU L AND C CONFIGURATIONS The reactance configuration for all Elecraft ATUs is an L-network of series inductance, with a capacitance connected to common before (radio side) or after (antenna side) the inductance (but not both) by a relay. It is a classic low pass filter. KAT1, Configs=1020, L=0 to 4.9 uH (16 steps), C=0 to 300 pF (32 steps) KAT2, Configs=131068, L=0 to 20.7 uH (256 steps), C=0 to 2420 pF (256 steps) KAT3, Configs=131068, L=0 to 17.4 uH (256 steps), C=0 to 2600 pF (256 steps) KXAT1, Configs=124, L=0 to 4.5 uH (8 steps), C=0 to 140 pF (8 steps) KXAT3, Configs=131068, L=0 to 15.9 uH (256 steps), C=0 to 2680 pF (256 steps) T1, Configs=32764, L=0 to 7.5 uH (128 steps), C=0 to 1300 pF (128 steps) The last two entries show a significantly greater range of reactance that the KXAT3 can insert...double the inductance and the capacitance of the T1. It *always* surprises me though, that in Elecraft-world all manner of antenna deformity is to be handled by an ATU magic bullet. Small-conductor ATUs are never your friend, if an antenna/feedline could be used that doesn't require tuner reactance.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
Us old f*rts have got to quit thinking analog. K3 CW is not keyed. It's effectively data-graphed and fed directly into a digital-analog converter (DAC). Remember, ZERO SIGNAL OUT in TX state is A STREAM OF DATA VALUES sent to a DAC that is RUNNING, not a stage that is switched off. The keying circuit is a subroutine. Paddle dash dot and Key In are read as a binary state on three lines to a CPU that go low when input is grounded. Shows up as a value in a register. There may be a bit more (or less depending on your point of view) to the lack of choice than it seems. When I look in the schematic for TX RX switching, all I see is unshaped on/off diode circuits all over the place that are switching from a common line or two, transiting the K3 circuits from TX state to RX state. You cannot follow the key line to an analog circuit that is turning an oscillator on and off, or breaking the feed of a steady oscillator to a following stage. So there is no capacitor to discharge for shaping the CW waveform, no resistor to adjust. This is not at all like my FT1000MP, where very loosely controlled cap values made some MP's clicks far worse than others. The K3 lets the RX to TX state change complete before it feeds the DAC any data that implies signal power output. Turning on the CW baud consists of some subroutine feeding some other subroutine numbers that are sent to the DAC, AFTER the K3 has gone RX state to TX state. Reverse for RX to TX. On the straight key side of 15 kHz TX IF, it's nuthin but arithmetic. The shape of the CW baud rise and fall transitions is a pile of numbers. It is oh so possible to monkey with the numbers to get a clear baud transition that has no artifacts in the adjacent channel once transmitted. And a baud transition, by the way, that is impossible with any analog component switch. Having a choice of keying waveshapes means that there has to be alternate piles of numbers or subroutines, and the extra running code to switch them. Why bother. They made it the cleanest CW signal on the band and went to work on something else. 73, Guy.

Re: [Elecraft] Antenna Tuner Or Not
For those that don't know Robert Heinlein: TANSTAAFL= There ain't no such thing as a free lunch. There is wisdom here. What Mike is saying is that, even though your auto-tuner may find a match to make the transmitter happy, there may be more efficient ways of coupling your signal to the ether. IR losses (Ohms law) within the tuner can eat up a fair amount of your QRP signal. This loss is higher when the inductor is wound with teeny-tiny wire. This is the case in some of these small internal ATUs. So, bottom line- 1. The internal ATU can make it possible to operate using an antenna that presents a wild reactance that must be cancelled out to make the transmitter happy. 2. When an antenna system (i.e. feedline plus antenna) requires a fairly large inductance to cancel out capacitive reactance in the system, this inductance can be provided by the nifty little ATU. 3. If the ATU has small diameter conductors creating this inductive reactance, the Ohmic losses in the wire adds up quickly. 4. The smaller the wire used for the inductors, the higher the losses. 5. To maximize your actual radiated signal, optimize your antenna system to require the least inductance to resonate it. 6 alternative to 5 (above), you could build an external ATU with a large roller inductor made from heavy gauge conductor. 7. For most situations, ignore 1-6 above, and just get on the air. 8. No matter what, Have fun! 8-) 73, Bruce, N1RX It *always* surprises me though, that in Elecraft-world all manner of antenna deformity is to be handled by an ATU magic bullet.

Re: [Elecraft] [K3] Phase Noise / CW Key Clicks
I too have heard such comments. My fervent hope is that someday someone will write a piece of SDR software that quantifies such things by callsign during a contest, and then posts the results to a web site afterward. I'm pretty certain that it's technically feasible right now to do so, at least for CW. Isolate a callsign just like CW Skimmer does when decoding text, and then look for surrounding bursts of spectral energy that track the main signal.

Re: [Elecraft] USB Sound Adapter
Simple question: I also jumped at the first message, what a deal, as I would like to get going on JT65 in a couple weeks. I ordered and received the same bubble pack, same (looking) dongle, but it clearly states on the manual that the mic input is mono. Is it not what it appears, like, is it a stereo jack that takes two signals in with a common shield?

( http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=310401470794ssPag eName=ADME:L:OU:US:3160 ) First, it IS stereo in and stereo out. There is some confusing wording even on the packaging but it is indeed stereo all around. Someone suggested that the chip MAY not be as advertised. As this IS from China (with a Taiwanese chip) and having dealt with Asia for decades, I opened it (not recommended for the inexperienced, it is glued shut). It is indeed the Via Vinyl Envy USB VT-1620A chip ( http://www.via.com.tw/en/products/audio/usb/vt1620a/index.jsp ). The Via driver from their web site loaded and recognized the chip so I am 100% sure it is genuine. It should be capable of: a.. 2-channel ADC with 90dB SNR, 16/24-bit supporting 44.1/48/96/192kHz sample rates a.. 2-channel DAC with 95dB SNR, 16/24-bit supporting 44.1/48/96/192kHz sample rates I have some photos if anyone is interested. It is a nice little board and looks to be well made. Both the input (Mic) and output (Headphones and SPDIF optical) are standard 1/8 stereo jacks with the output having the additional optical coupler mounted just past the electrical contacts. It works great with HRD but I have no way of testing it for I/Q use as my KX3 is still a dream and my K3 is not equipped for I/Q out. Maybe someone better equipped and more knowledgeable could put this little guy through some tests??? If so contact me. FYI my QTH is Watsonville. BTW, I have no financial interest in this at all.

Re: [Elecraft] K3 Speaker plug
Bill, I do not understand the utility in connecting both the left and right speaker outputs to a single speaker - but I don't think it will do any harm. Connecting the audio amplifiers together is different than shorting the right channel to ground by inserting a mono plug. Why not connect to stereo speakers and enjoy the AFX or if you have the subRX, the combinations of main and SubRX receive in each ear (speaker). Spread the speakers out so the left speaker is in the left ear and the right speaker is in the right ear. If you put the speakers close together, you will not observe the effects. I do believe corrective actions have been taken for the audio amplifier shorted problem, but my memory is fuzzy about what and when. 73, Don W3FPR On 9/13/2012 3:04 PM, Bill Wiehe wrote: Just want to be sure that I understand the External Speaker Jack stereo vs mono plug operation.

[Elecraft] [K3] Thank you Elecraft
I was trying to figure out why my K3 wasn't transmitting in CW as part of screwing up my courage to try a first CW QSO. (I want to wait a while yet and do more listening before I actually try.) I fired up the K3 utility to check that the 2.7KHz filter was enabled for CW transmit. It was. Oh rats, I'll actually have to read the manual. Well, I noticed that I was a bit out of date on firmware updates, so I saved the configuration file from the K3 and clicked install all. W1AW code practice switched in and out as the K3 reset itself during the firmware loads. I wondered if the reload had fixed the problem so I cranked the power way down, found a clear spot on the band and keyed my call. VFO B showed up with the message VOX=OFF. Aha! You need to turn VOX on for QSK mode. Problem solved. No manual referenced. The UI is as good as the rest of the radio.
