[Elecraft] K4 RX dynamic range
Before putting my money up front for the first run of K4D I need to know what is the dynamic range of the K4D RX at 2kHz spacing. K3 is 105 dB and K4D? If it is 20dB lower than K3 than it would be 85dB-correct? __ 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

[Elecraft] KAT500 and K3 Powering sequence

Re: [Elecraft] KAT500 and K3 Powering sequence
George, Thanks for your suggestion. That will work. For some reason I was under impression that I would have to TURN ON the KAT500 first. My KAT500 will be also connected to 12V buss. My interpretation of applying power was wrong. I just received my KAT500 KIT. Thanks again :) Mark WQ7X Mark, My understanding from the manual is that the KAT500 must be on when the K3 is turned on for the Aux connection to work properly. In my shack this is accomplished by connecting the KAT500 directly to the 12 volt buss; that way it is already on when I turn the K3 on. This works well for me. Probable doesn't matters if you elect to not use the Aux cable connection.

[Elecraft] KPA-500 high gain modification?
Interesting. I have build 600W amp with four Motorola MRF150 transistors and I can easily get 600W output with 7W input. This was tested with input attenuator removed. Are those Mosfets in KPA500 that much different? I also would like to purchase the KPA500 but only if I could get 15 dB gain. It would be great to drive KPA500 with KX3 10W and get around 300W output power. I’m pretty sure that KPA500 has some form of attenuator at the input. Mark WQ7X But I would buy a second KPA500 in a heartbeat if I knew I could modify it for 10 watts drive for full output! I think you're being optimistic about full output with 10W drive. The VRF-2933 is rated for 23 dB gain (typical). With perhaps 1 dB loss in the low pass filter, a dB or so in the output transformer, roughly 3 dB in feedback to improve linearity one dB in the input transformer, bias decoupling, gate balancing, and two dB in the input matching comes very close to the roughly 15 dB gain limit in the US regulations. Some of those values are based on application notes from Motorola, MicroSemi and APT for similar MOSFET designs while some values are from Elecraft designers. In any case, the inescapable conclusion is that there is no magic modification to get the additional 2 - 3 dB of gain necessary to get 600W with 10W of driver from the KPA-500. 73, ...

Geoff, You would need more like 35W amp.

I assume that during receive this amplifier would have to be bypassed. 73, Geoff LX2AO __ 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] New 3.41 IMPROVED RX LOW-FREQUENCY RESPONSE in AM/SSB/CW MODES
To me there is no difference between 3.30 and 3.41. Same low freq. response. However, for my needs it is OK. Yes, I'm adjusting shift and width. There is one problem with the new 3.41- the DSP high pitch noise level is higher (3dB or so) than with 3.30. Condition: RF gain at 12 o'clock AF set for normal listening level with good headphones. Antenna switch is being used to ground the antenna. Listen to the band noise on 20 or 17m and ground the antenna. Now compare internal DSP noise to band noise by using antenna switch Do the above with 3.30 and than 3.41. My K3 SN is above 3000. I like 3.30 and I'm hoping that DSP gain distribution/noise level in future firmware will be the same as in 3.30. There is also difference in DSP gain between 3.30 and 3.41. __ 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

Than again the same thing happened 70% of the time. This only happens if NR is engaged on A and B VFO and while switching from A to B. Just did it again-now on the internal speaker. Wow!! it is loud.

To: Elecraft Reflector elecraft@mailman.qth.net Date: Saturday, May 3, 2008, 5:29 PM We've just completed the most extensive K3 firmware update ever. The full list of changes is provided below. *** NOTE *** You must use the latest version of our firmware loader (K3 Utility rev 1.1.4.1) or else you won't be able to load all components of the upgrade. It's available on our K3 software page, along with release notes: http://www.elecraft.com/K3/k3_software.htm As usual, if you have any difficulty with the firmware upgrade, send email to [EMAIL PROTECTED] Both Lyle, KK7P (DSP firmware) and myself (MCU firmware) will be closely monitoring your results in case further tweaking is required. I'd also like to thank all of our K3 customers for their patience. This firmware release was delayed several times due to testing, engineering staff vacations, etc. Our field testers have been pounding on interim releases for weeks (thanks, guys). I hope you'll find it worth the wait! 73, Wayne, N6KR * * * MCU 1.87 / DSP 1.69, 5-3-08 This release includes improvements in all areas. Changes are categorized below. NEW FEATURES: * CW KEYING IN SSB MODES: While in SSB modes, you can now send CW without changing modes or using an offset. The other station will hear the signal at your CW pitch. This is especially useful on VHF bands when SSB signals can’t be copied. To enable this feature, go into CONFIG:CW WGHT and tap ‘1’ until you see SSB +CW. * FM MODE ADDED: Requires FM filter installed in slot FL1. Those not needing FM mode can set CONFIG:FM MODE to OFF. To set up a repeater offset: Use the CONFIG:RPT OFS menu entry, then hold ALT to select -/+/simplex (-/+ appear under the FM mode icon). To set up tone encode: hold PITCH, then rotate VFO B to select PL TONE or PL OFF, and rotate VFO A to select the desired CTCSS tone. (When PL TONE is on, a letter ‘T’ will appear near the FM mode icon.) Repeater offsets and PL tones are stored per-band/per-memory. * VARIABLE AMP KEYING DELAY: Added CONFIG:TX DLY menu entry, which sets the time from KEY OUT jack (active low) to first RF in 1-ms steps, from 8 to 20 ms. To minimize loss of QSK speed, use the shortest delay that works with your amp. Most will work with the default (minimum) setting of 8 ms. * LINE OUT ALLOWS RX/TX AUDIO RECORDING: Normally, CONFIG:LIN OUT sets a fixed-level, receive-only output for main/sub (L/R), compatible with digital modes. Tapping '1' switches LIN OUT to =PHONES, where the line outputs match headphone audio, audio level controlled by AF/SUB gain controls, and both RX and TX audio available. * SIMULTANEOUS USE OF MIC AND LINE IN: If the MAIN:MIC+LIN menu entry is set to ON, and MIC SEL = FP or RP, the present mic OR line in can be used for transmit audio. NOTE: Setting MIC SEL to LINE overrides the MIC+LIN menu entry (its parameter becomes N-A). When MIC+LIN is in effect, rotating the MIC control shows MIC GAIN. The op has to set MIC SEL to LINE temporarily to set LINE IN gain. * S-METER ABSOLUTE MODE: Use the CONFIG:SMTR MD menu entry. Set to ABS (absolute) to have S-meter stay constant with preamp/atten settings. Default is NOR (where PRE/ATTN affect the S-meter). ABS mode requires recalibration (SMTR OF SMTR SC). RECEIVE: * SSB RECEIVE PASSBAND EXTENDED AT LOW END (now 100 Hz; was 200 Hz). * AM RECEIVE WIDTH RANGE INCREASED: The WIDTH control in AM mode now has a range of 2.8 to 10.0 kHz. Wider settings provide outstanding fidelity for hi-fi speech and other wide-band signals. This is the *IF* filter bandwidth -- the traditional way to show bandwidth for AM, because the required IF bandwidth is twice the modulation bandwidth. NORM selects an IF bandwidth of 6.0 kHz in this mode. WIDTH settings above 6.0 kHz will not be useful unless you have an FM-bandwidth crystal filter installed (at FL1). * IF A 2.8 KHZ FILTER IS INSTALLED, SSB NORM BW is 2.8 kHz (was fixed at 2.7 kHz). * AUTO-SPOT (SPOT with CWT ON) now works with both very weak and very strong signals. * PSK AUTOTUNE ACCURACY improved. You may still need to use RIT (FINE steps) to tune in signals for best built-in text decode. (Also see CW-to-DATA in the Owner’s Manual.) TRANSMIT: * TRANSVERTER POWER CONTROL: The value set in CONFIG:XVn PWR now correctly sets a fixed power level on the associated transverter band (0-1.50 mW or 0-12W). * POWER

Re: [Elecraft] K3: SSB - WPX - Filters - Controls
I have made 700 QSO's in WPX SSB contest(part time). I have also tried different adjustment on the K3 including RX EQ. I have to say the same thing It seemed I was always fighting some sort of side band splatter or stations close in on the frequency. Splatter is always in the contest but not as pronounced as with K3. I don't know if it is the freq. response or something else with DSP. I was so tired after few hundred QSO's. I have switched to TS930S. With TS930s it was much better. Signals were much cleaner more dynamic and the splatter not as offending as with K3. I have 2.7kHz filter in my K3. I like K3 very much in CW CONTEST but don't like in SSB contest at all. Also, for some reason the output power from the K3 was fluctuating in time. I had to keep adjusting PWR. My alpha 87A was showing 1500W PEP and than about 900W and so on. Than after 10 second or so again 1500W. Looked to me like ALC action in the K3 was not always the same. I don't connect ALC to the amp. Same thing when I switched to IC-4KL amp.

This is by no means a put-down of the the K3, because I am not sure I am operating the rig correctly. After all it is a SDR and it is new. During my first foray into SSB Contesting with the K3 during WPX, I found that I need either: 1. Understand more about the DSP and the controls for BW, Hcut and Lcut 2. Obtain a narrower roofing filter for SSB - like a 1.8 Khz filter 3. Or both. I spent some time trying to find the sweet spot in the radio for SSB using the 2.8 Khz filter. I don't think I found it. At least, I am not satisfied. I tried narrowing up the filter bandwidth to 2.4 or 2.2some times 1.8. I tried shifting it up and down the bandpass. I tried to use High Cut and Low Cut depending on where the offending signal was coming from. AGC was on Slow with the standard settings. Used the RIT a lot It seemed I was always fighting some sort of side band splatter or stations close in on the frequency. Maybe it was just a crowded 20 meter band, but the same things happened on 40 meters. Do I need to go to a 1.8 Khz filter to give the DSP a break? Do I need to understand and play with the RX more to make sure I am doing it right. I would like to some feedback and comments on how other people set up their K3s for SSB contesting. I want to learn more about this radio. Lee - K0WA In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it.

Re: [Elecraft] K3 SSB Noise Reduction
Lyle, So, with SSB signal S9 and noise S2 with NR= F1-1 signal shouldn't drop to much?? SSB signals always drop about 3dB. Even signals SSB with good S/N. I understand all what you are saying but how hard it would be to increase AF gain when NR is engaged?

Anyone tried it with CONFIG:AF GAIN set LO? I haven't, just wondered. If there was a config control for an offset, it would need to be based on the 4 'strenghts' I think, not on the Fx number, but the digit after the - The first value you see -- the Fx -- has to do with the aggressiveness of the filter. The second value you see specifies the blend of processed and unprocessed audio. Keep in mind always that the denoiser is not a denoiser; it is a signal enhancer. It will act to suppress *everything* until it decides there is some sort of signal present, then act to pass that signal. The more the signal appears to be a pure tone (like CW) the faster and more decisively the algorithm acts. The less it looks like a signal (noisy SSB comes to mind) the slower and less decisively the algorithm acts. This is why the audio level is low to begin with. For CW with reasonable S/N, it usually quickly builds up to the same overall amplitude as without the NR. For SSB with poor S/N, it builds up slowly and to a lesser overall amplitude. Thus, observations that the signal amplitude sometimes or often appears reduced are correct. The disagreements about how much it is reduced are also correct. It depends on the NR settings, the S/N of the signal you are listening to at the moment, the type of signal, the IF and AF bandwidth... FWIW, I usually have mine set to F1-1 or F1-2 for SSB operation. YMMV. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 SSB Noise Reduction
David, There is nothing to think about. There is for sure significant reduction of volume. Just listen to the station on 20m (low noise) using speaker 4 feet away. Adjust the volume (to low level) to the point that you could still understand what the person is saying. Than push NR. I bet that volume will drop to the point that you will not copy the station. Certainly, not compensating for AF gain loss when NR is engaged makes noise reduction function work much better NR in CW works fb. Little AF gain Loss.

Curt, Tx SSB.This is normal. SSB tx signal from K3 is good but I understand that in the future there will be some improvement (firmware). I have adjusted compresion to 25 and than MIC gain to the point that there is no distortion. That way I can get more dynamic signal (good average power).

Fwd: [Elecraft] K3: Interim Build Report
Dave, My K3 arrived with all the parts. SSB: There were many postings about SSB mode (including mine). Some how, there was no response from Elecraft about this. I have many friends in EU who are waiting for that DX/Contest audio from K3 before they decide to order one. I don't understand why Elecraft is not responding to this issue. I just would like to know that Elecraft has intention to improve SSB mode. 73 Mark WQ7X --- David and Dianne on Comcast [EMAIL PROTECTED] wrote: Date: Sat, 09 Feb 2008 18:22:20 -0500 From: David and Dianne on Comcast [EMAIL PROTECTED] To: elecraft@mailman.qth.net Subject: [Elecraft] K3: Interim Build Report Hi Everyone, As I posted here at mid week, K3 #371 arrived from Aptos in fine shape. I have begun the build and thought I would share some comments both positive and negative with all. You opinions of course will most likely be different but here are mine so far: Positive: The kit was packaged magnificently. The care in packaging is first rate. The manual is by far one of the most comprehensive I have seen in building many kits over the years. Clear, concise and detailed but very logical and easy to follow. Build quality of the boards is indeed elegant. Fit and finish is simply excellent. Tolerances are amazing. It is a work of engineering art. Congrats to Eric and Wayne of all of this. They should be proud of their baby. Negative: Yup I have a negative. Of all of the kits I have built over the years, many of them fairly complex, from Heath, LDG, W9GR and many others, this is the first to arrive short parts/hardware. And while the shortage is minor, it is specialized and significant enough to stop me cold in the build process and add yet another week to the final K3 experience. Simply put, it has been deflating. Yet more delay. While Elecraft was attentive to this matter over the phone and in a response from K3Support, I am still not sure if the parts are headed this way as no confirmation has been positively received. This will be my last kit experience. I should have bought it factory assembled as I planned originally. But I bought into the kit mystique. Never again. Concerns: I am both a CW and SSB operator as non-contesting DX'er. SSB TX issues are important to me. Several reports are surfacing here and elsewhere from very reputable sources about the current lack of SSB bandwidth and the lack of more powerful modulation. I urge Elecraft to address these issues ASAP (now perhaps with more priority than the second receiver.) This will be a deal breaker for me if not rectified. IMO it should have been correct out of the box. This K3 will be evaluated against my highly modified Ten Tec Omni V.9 which has for my operating requirements beat out every transceiver on both CW and SSB since its arrival here at this QTH, bar none, including my Pro III which for all its true Rx warts is a pretty darn good value for the $$. I paid my $$ and took my chances and hope that this will all get rectified in the end. And for those of you who may think that I should not air complaints in public, I ask, did yours arrive complete? My $.02 73 de N1LQ-Dave ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Fwd: [Elecraft] K3 SSB width control
Same here. It will go back in my case to 2.5 and 2.7 after I push and hold NORM.

I've got the 2.8Khz filter, and the filter settings in config menu are all normal. When I'm in USB or LSB with the passband centered and I rotate the width control, my width options now are 2.3/2.5/2.7 (2.9 will switch over to the 6.0Khz filter as expected). When I normalize, it is giving me 2.7Khz. I really want to set it to 2.8Khz now and I can't figure out how. I definitely know that I've previously seen 2.4/2.6/2.8 as the width options and 2.8Khz for normalization but I can't seem to get there from here. Are other folks seeing this? Am I missing something - why is the K3 flipping back and forth between these width options? Maybe this whole thing could be solved with 100hz or 50hz granularity of the width control in ssb.

[Elecraft] K3 SSB average power output
With SSB mic level adjusted to the max level (ALC to the max)the average power measured on external meter is only 4 Watts with distorted audio (power output set at 110W). If I use external compressor the average power is still only 4 Watts. This is done with CMP gain at zero. This is not normal. Contest or ESSB guys will not like that. With K3 compression to the max average power is about 8 Watts. K3 is a great radio but not in the transmit SSB mode. If Mic gain is adjusted properly so there is no distortion than the average power is even lower. I'm sure that this could be improved in firmware. If not than K3 would not be that good in the contest and Dx -ing on SSB Anybody has the same experience? I remember that Toby from Bavarian DX Club and some other guy was talking about SSB audio. I'm not complaining but I would like to have SSB signal comparable to radios like TS850, Ft1000D and so on. I hope that Elecraft will put this on their agenda. Beside that, K3 is superb TRX-the best.

Fwd: Re: [Elecraft] K3 SSB average power output
My mistake. Sorry. I should be more precise. I should point out that I was comparing to FT1000D. Never mind that my meter is showing 4W. Every meter will show different average output power. And yes I have two peak power meters. Am I correct if i say that peak power meter will show let say 100W with 3dB and 20db compression. That tells me nothing about average power and I'm very interested in average power in SSB. That is what makes signal stronger at the receiving side. If we are interested in just peak power than why bother with speech processors. Anyway here is the comparison: FT1000D 7W CMP off 30W CMP ON K3 4W CMP off 20W CMP ON MIC: HC5 and Goldline PRO And yes both TRX peak power was set at 90W. K3 peak power on 20m 90W with TXGN at 3dB. On CW 120W. All what I'm trying to say is that perhaps K3 SSB signal could be made more dynamic.

You need a peak reading wattmeter. If anyone ever uses an average reading power meter to try to figure out the talk power of a radio, I guarantee you that they are putting out crude. Even with the K3 compressor set up more than it should, your peak to average ratio is very high. I have the Autek (sp?) peak reading meter in line, and it shows exactly what is going on. On SSB, I get 100 + watts, as I talk. On CW, I get what I dialed into the K3, and on PSK, I get around 10, based upon the audio gain settings. PLEASE! Never ever use an average reading wattmeter for anything other than key down observations. Invest in a peak reading meter. I like the Autek because it has two meters, peak reading forward power, and peak reading, auto adjusted SWR reading. One has to do nothing but look at this meter to tell what is going on. tom k8tb mark roz wrote: With SSB mic level adjusted to the max level (ALC to the max)the average power measured on external meter is only 4 Watts with distorted audio (power output set at 110W).

[Elecraft] K3 #296
I like my K3.RX is so quiet. Very crisp CW tone and super clear SSB reception. However I have some small problem's : 1. On SSB with headphones plugged in and noise reduction engaged, during transmission the audio comes from the internal speaker in the form of short bursts. It is impossible to transmit with NR in ON position. In the menu, speaker is on 1. This will happen more often if RF gain is decreased and when shift is being adjusted. VOX is ON. 2. On SSB only. When NR is engaged noise drops but also the level of the main SSB signal will drop significantly. On CW is perfect. I'm sure that this could be corrected in software. The one thing I don't like about VOX is the fact that its sensitivity is NOT independent of MIC gain like in FT1000D. This probably cant be changed in software. For those who didn't try very good quality MIC on SSB I strongly suggest to do that. The transmit audio is superb. HC5 is good but doesn't even compare to Goldline Pro or condenser MIC. Question: Do I need 6kHz filter in order to try ESSB. Can't find it in the menu.
