[Elecraft] [K3] K3 ACC Connector
Hello all I just purchased an Ameritron ALS-600 amp which does band switching. For bandswitching, they suggest interfacing it with the K3 through their ARI-500 ( for cabling reasons). This set up for the K3 uses the ACC LP Key Out pin to key the amp...not the Key Out RCA jack. The Amp will not key...if I put 40W in I get 40W out. Bandswitching works fine. If I hook the K3 and the ALS-600 in the non bandswitch mode and use the Key Out RCA jack the amp keys fine. I would appreciate any help Joe W1JGS - Joe W1JGS -- View this message in context: http://n2.nabble.com/K3-ACC-Connector-tp2862150p2862150.html Sent from the [K3] 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] [K3] K3 ACC Connector
Joe, Use the ACC for the band switching connection and use the KEY OUT to do the PTT. In other words, separate cables. 73, Bob W5OV -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Joe G Sent: Monday, May 11, 2009 5:05 AM To: elecraft@mailman.qth.net Subject: [Elecraft] [K3] K3 ACC Connector Hello all I just purchased an Ameritron ALS-600 amp which does band switching.

I use a pair of amplified Labtec computer speakers. They sound good, have convenient headset and mike inputs, volume and balance controls. I don't think they look particularly good, but you can find computer speakers of all types. Some you will need to RFI doctor with ferrite beads. They are inexpensive to buy but I had these in my closet from a junked computer.

Re: [Elecraft] External speakers for K3?
By match closely, do you mean physical appearance or impedance? Speaker characteristics for SSB and CW may differ. The best overall compromise I've found over the past 45 years is the Heathkit HS-1661. It is very efficient, as in LOUD, has a thick aluminum cabinet with no vibration or peaky resonance. Radio Shack sells a replacement speaker that fits perfectly if needed. For CW only, the MFJ ClearTone, MFJ-281 is hard to beat. It peaks strongly at 700 Hz and is very sensitive. Cost about $12. The HS-1661 shows up on Ebay occasionally and usually sells for about $30 or so. I painted mine black. Modern stereo speakers will work but they usually have higher power ratings and require more power. Amplified speakers will also work well but could be affected by RFI depending on brand and model.

Re: [Elecraft] External speakers for K3?
Go for two, then you can take advantage of AFX. I use two small black communications speakers, designed for vehicle mounting and optimised for voice and are only 3-4 mm taller than the K3 -- one either side. Really does enhance AFX on SSB and they look good too. And they were less than GBP 7 each! Peter GM8GAX I would like to find or build an external speaker for my K3.

This can only happen if you have CONFIG:SPKRS set to 2. If you set it to 1, the right speaker channel is turned off, so a mono plug can be safely used. In addition to this, an upcoming beta firmware release detects the case where SPKRS is set to 2, a mono plug is inserted, and speaker volume is set to a moderate or high level. (The firmware looks for excess receive-mode current drain due to the AF amp IC going into thermal shutdown.) If this happens, the K3 will automatically set SPKRS to 1, reminding you with a brief flashed message. 73, Wayne N6KR --- http://www.elecraft.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

[Elecraft] K3: Elecraft Utility and second receiver
I installed the second receiver recently, and am totally addicted to the diversity reception. Using my R5 vertical as the second antenna, with my horizontal beam for the main. The R5 is of course useless as a transmit antenna on 40, but it picks up enough signal for receive (no tuner on it). Haven't put any extra roofing filters in the second receiver, and with the lower received signal strength on the vertical I doubt that I will need to. Now to my question: The Utility happily loaded the DSP firmware into the second receiver, but I didn't see how to set up the roofing filter configuration from the Utility, so I did it using the radio's menus. Surely I am missing something in the Utility?

[Elecraft] K3: N1MM for Field Day
I just proposed to our Field Day chief that we use my K3 this year (with extra precautions to avoid power interruptions, and with a computer available for re-loading the firmware if necessary). BTW I first did some hurried testing with the K3 running off my linear Astron PSU cranked down to 11.0 V (only 10.5 V indicated on the K3 at 100W due to cable drop). At this low voltage and 100W there seemed to be a slight increase in IMD; none at 65W. I now have some experience with N1MM (but not for FD) and like it a lot. So, I also suggested we try it for FD, along with the computer infrastructure needed. Somehow, it just seems harder and harder to get along without a computer What we have been doing for FD is using a DOS program on an ancient laptop for logging... The initial response from the FD chief is concern about log format for submission. I mentioned the information available in the N1MM manual. Question: I think many of you already used N1MM for FD last year. If so, could you please send me some detail of the steps you went through to combine the N1MM output with other information to create the complete submission?

Re: [Elecraft] K3 Power supply
I am using a Jetstream JTPS28M and I am happy. I have a few birdies, but I am not sure which come from the switching supply and which come from the computer. They don't give me enough trouble that I have investigated. The JTPS28M is only $99.95 so I am not sure it is worth trouble shooting and changing caps. The rule of thumb for electrolytic capacitors that that I learned year ago was to change them after 7 years. I suspect that modern caps are better than the ones we had in 1960, but that still may be your problem. There are plenty of places to buy caps on the internet and I don't know any place that it is more convenient to buy local. I live in the Houston area and still need to buy such things by internet. Fry's is only 5 miles away but if they have the part in stock they will have one when I need four. EPO will have four that are old stock or surplus that may not be any better than the one removed. So I buy from Allied or one of the other on line vendors, wait a week and save the gas.

Re: [Elecraft] K3 Power supply
- Original Message - From: Merv Schweigert k...@flex.com I started to try and find the problem and using another receiver I find the Astron SS-30 is generating all sorts of noise. I have used this supply for some time and have not noticed the noise before. Merv, For weight considerations, the SS-30 supplies were selected for the Ducie Island expedition this past year. This problem you mention, or a very similar one, was evident during the VP6DX expedition from the time that Robin started making tests while underway on the Braveheart from ZL to FO. We added extra filtering internally. We grounded extensively. We cleaned the case cover screw holes both on the main chassis and on the cover to improve bonding to the cover. We were never able to make them clean. All supplies performed in the exact same manner. We were float charging small batteries to keep the K-3s and the ancillary equipment running while the gensets were being refueled and having oil changed. The extra capacitance of the battery helped with the DC filtering but most of the stuff was of a frequency that the battery and other filtering could not remove. And we couldn't keep it inside the case. The fact remains that the harmonics of the switcher were a very real problem for us, especially on the lower frequency bands. The most annoying situation was the harmonic signal moving around, slowly up and down the band such that we could not avoid it at times when we were in the middle of a tough one on 160 and were trying to dig it out of the noise floor. We had to wait until the birdie slowly slithered on by or many times I just reached and turned the SS-30 off during a difficult contact. 73 de Milt, N5IA __ 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] K3 Power supply
Wonder what supplies are being used with the K3? Merv, For the shack, I gave up on switch-mode power supplies since I could not find one that produced a low noise floor on all bands. For years, I was unknowingly putting up with a high-level noise floor until I purchased the SDR-IQ and began seeing broad bumps in the viewed spectra response. The bumps were attributed to switch mode power supplies, switch-mode wall supplies, and some USB adapters. By changing switch-mode back to old linear technology and a combination of changing the USB adapters as well as using multi-wound #31 ferrite cores (wound K9YC style) on both ends of the USB cables, I finally have a flat noise floor on all bands. I am sure there are quiet switch-mode supplies out there. But with all the other noise sources I have to contend with, I don't want to be asking myself if some new grunge I'm hearing in the future is attributed to my power supply. My guess is that many of us are living with high noise floors from switch-mode products and do not realize it -- until a PAN adapter is added and the noise floor can be seen. Spotting sharp switch-mode and LAN-type grunge is easy without a PAN adapter, but it's the very broad noise (e.g., gentle rise and fall over 100 kHz) that's deceptive when one tunes the band. The shack supply here is now a surplus linear Agilent 6652A. These sell new in the $4K range but are only a few hundred $$ if you catch the right on-line sales for surplus product.

Re: [Elecraft] K3 Power supply
Merv, if you're suddenly getting hash from two formerly-clean switchers, I'd suspect something else, such as a bad mains ground on the circuit feeding the supplies or a change in the rig's grounding system that is now introducing some sort of a ground loop return. Have you made any changes to your antenna situation lately? If feeding with coax, are the shields intact and properly terminated at the rig? After over 50 years of fixing electronics, I've yet to find two similar failures in separate gear that were coincident, no matter how often I've tried to convince myself I was finally experiencing the first time. It's always something in common to both. As for power supplies in general, my linear Astron 20 handles my K3 FB. (I don't try to crowd out an extra 1/10 of an S-unit above 100 watts by running the power control wide open keeping the demand comfortably within the Astron's 20 amp ICAS ratings on CW/SSB. If I want to run a 100% duty cycle mode such as RTTY, I back down the power.) The linear supplies may be heavy, but I don't take mine back-packing (the extension cord would weigh more than the supply if I did ;-) So it sits under the operating desk where I don't care how heavy it might be.

[Elecraft] K3 - Data A pitch
Seen this asked before but without response so does anyone know if it's possible to change the centre frequency of the audio in Data A? It's about 1500 Hz at the moment and wouldn't mind being able to drop it a bit unless there's a good reason not to.? Also my (old) manual suggests you should be able to use the dual passband filter for rtty while in Data A but I assume this was a mistake?

But if you do that, you won't be able to take advantage of your narrow filters for PSK31 etc. because your filter will fall outside the passband.

Re: [Elecraft] [K3] NR distortion with 3.11
Yes, the low slope (and perhaps the threshold) for my AGC settings increases the apparent NR distortion. So you have to make a decision better AGC response or clearer audio when using NR. Since I rarely use NR, I have made my choice. It may be that someday soon we may 'have our cake and eat it too' when Lyle works on the NR algorithms, but for now we have to make those choices. 73, Don W3FPR NZ0T wrote: I should add that I recently changed my AGC settings to those suggested by Don W3FPR to make the K3 sound more like a K2: AGC PLS off AGC SLP 002 AGC THR 008 AGC-F 140 AGC-S 010 Any other AGC settings that are better?

[Elecraft] NUE-PSK and the K3/100
I'm querying the group regarding the NUE-PSK settings and an Elecraft K3 ... I'm having some trouble getting the transmit settings correctly. Here's what I've done so far ... after Googling, reading, and experimenting ... MODE: Data A Power set at 20 watts Line Out is from the back of the K3 with the Lin Out menu setting at 20 Line In is to the mic jack wired like NUE-PSK cabling document suggests. Line In menu setting is FP:L (Front Panel Low and no bias) Mic Gain is 30 ... I put the K3 into TX Test mode, then F8 on the modem to throw it into transmit. I adjusted the Mic Gain and the NUE pot to get barely one bar on the ALC meter. Any more ALC than this causes the K3 to show ALC spikes episodically to 6+ bars with great transmit sound distortion. I can only imagine how the signal looks. Through Google, I found several folks doing different types of setups with the K3, so I read all their suggestions and tried to adapt them. I never did get the 4 bars of ALC setting to be satisfactory. It seemed that I was greatly overdriving the output. On the other hand, the NUE-PSK information about the K3 suggests no ALC bars showing. The above settings give me 1 bar on the RF out ... so 10 watts or less. I didn't get any responses on 20meters this morning to CQ so I don't have any feedback on proper settings. Does anyone have any other suggestions for the K3 setup? Finally, I'm not a beginner with PSK31, but I am new to this interface with the K3 ... I have searched the Elecraft relector archives but didn't find anything specific to the NUE-PSK ... Thanks in advance. I take the Digest so will take awhile to respond, unless you respond off list ... gene WG7GW __ 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] K2: HRD Power Control Anomaly
I'm operating my K2/100 (KPA100+KAT100 in EC2) from Ham Radio Deluxe, which works just great. But just now I was playing around with the HRD power control slider and discovered some anomalies. If I set the power on the K2 to say 50w, then move the HRD power slider down to 11 w, the LCD power readout on the K2 follows the HRD slider down appropriately, but the KAT100 PWR RANGE LED stays in HIGH. If I then transmit, the power is actually what I set it to (11w). So does that mean that I'm driving the KPA100 at QRP levels instead of using the K2 PA and bypassing the KPA100??? Moving the slider to other power levels (without moving the K2 power control) results in the same thing - power out follows the HRD slider, but the PWR RANGE LED stays at HIGH no matter if the power is set to 11w. Now if I start with the K2 power control at 11w, first of all, HRD displays 10x the actual power setting (i.e., 100 for 10w). That's easy to get used to. But if I crank the HRD slider up beyond 10w (e.g., HRD slider to 150 or 15w), the actual power output, and the K2 LCD power display, go to 15w, but the KAT100 PWR RANGE LED stays in LOW. Again does that mean that I'm driving the K2 PA to 15w and not going through the KPA100??? Is this a HRD issue or a K2 CAT command issue??? Kinda strange! 73, Randy, KS4L __ 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

Randy, If your K2 firmware is less than version 2.02e then the problem is with your K2 firmware. If the firmware is 2.02e or greater, then HRD is the problem. What version of HRD are you using? If it is an older one, that may be your problem. See the K2 Programmer's Reference. The Extended form of the PC command must be used to change the power from the low range to the high range. I don't know whether Simon has implemented the Extended version of the PC command in his software. You may want to ask that question on the HRD forum. I cannot check it out here, I have only the QRP K2 and no KAT100. 73, Don W3FPR Randy Moore wrote: I'm operating my K2/100 (KPA100+KAT100 in EC2) from Ham Radio Deluxe, which works just great. But just now I was playing around with the HRD power control slider and discovered some anomalies. If I set the power on the K2 to say 50w, then move the HRD power slider down to 11 w, the LCD power readout on the K2 follows the HRD slider down appropriately, but the KAT100 PWR RANGE LED stays in HIGH. If I then transmit, the power is actually what I set it to (11w). So does that mean that I'm driving the KPA100 at QRP levels instead of using the K2 PA and bypassing the KPA100??? Moving the slider to other power levels (without moving the K2 power control) results in the same thing - power out follows the HRD slider, but the PWR RANGE LED stays at HIGH no matter if the power is set to 11w. Now if I start with the K2 power control at 11w, first of all, HRD displays 10x the actual power setting (i.e., 100 for 10w). That's easy to get used to. But if I crank the HRD slider up beyond 10w (e.g., HRD slider to 150 or 15w), the actual power output, and the K2 LCD power display, go to 15w, but the KAT100 PWR RANGE LED stays in LOW. Again does that mean that I'm driving the K2 PA to 15w and not going through the KPA100??? Is this a HRD issue or a K2 CAT command issue??? Kinda strange! 73, Randy, KS4L __ 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 No virus found in this incoming message.

Re: [Elecraft] K3 Power supply
Jim, I take it you were commenting on the S-meter. I don't have the rig anymore; I sold it to buy the K3. It was generally working very well, and it behaved this way from day one (I bought it new around 1992) and I never saw a need to align it. The buyer has not complained. My statement was based on starting at S-9 and applying attenuation 6 dB at a time. My memory may be slightly off, but generally I saw the same behavior in the 1000D as in my old IC-735. The meters would be quite good above S-7. Starting at S-7 and attenuating another 6 dB they would indicate about S-5, and after another 6 dB the needle would be at 0. I remember memorizing this and using it to give reports. Because it seemed so consistent between the two rigs, I formed the opinion that it was the consensus of the manufacturers, and again saw no reason to question the 1000D's alignment. Of course, with preamplification on, the meter would start moving at a lower level, maybe S3. Over the years I have seen comments in articles that have seemed to avoid generalizations and instead said things like S-meter calibrations vary a lot from receiver to receiver. I wouldn't be surprised if Yaesu had changed the AGC parameters sometime during the long production run. 73, Erik K7TV - Original Message - From: Jan Erik Holm sm2...@telia.com Cc: elecraft@mailman.qth.net Sent: Monday, May 11, 2009 8:25 PM Subject: Re: [Elecraft] K3 Power supply Sorry but this is totally wrong. In this case your FT-1000D was either broken or not aligned properly. If you still have it align it per the service manual and you will see something totally different. 73 Jim SM2EKM -- Erik N Basilier wrote: Merv, My experience with the FT-1000D was that the S-meter didn't start to move until the actual signal strength reached S-5 or so.
