RE: [Elecraft] Bass in audio is good
Excellent job Mike! And if someone doesn't like bass all they need do is adjust the EQ. Now we have a choice. No, adjusting the EQ messes up digital modes. In addition, additional bandwidth below 200 Hz makes the signal illegal on 60 meters where the occupied bandwidth is specified at 2800 Hz maximum. Good engineering practice calls for a default transmitted audio spectrum of 200 Hz to 2800 Hz: http://www.arrl.org/FandES/field/regulations/faq-60.html If you want to act like a spoiled child and be a bandwidth pig, use your EQ to mess up your own signal. Allow the others to occupy 200 - 2800 Hz and be legal on 60 meters without any need to screw around with the EQ and effect other modes. 73, ...

[Elecraft] K3: FW issue, XVTR operation TX power settings
Hi, With latest (MCU 1.88 / DSP 1.70) FW (and also versions sbefore) I have the following strange behavior in transverter operation: K3 SN 533 Using an XV144, set up as XVTR1, 1mW drive power. Tune PWR is set to fixed 5.0 (Config Menu) When I switch to the transverter band and do TAP TUNE, a carrier with the nominal power (1mW Out on K3) is sent. After terminating the TUNE operation, the power settings get messed up, usually the current power setting is dropped to 0.00 mW (seen by double tapping the PWR control). Giving some movement to the knob, has the power setting jump back to the configured value (in XVTR settings) of 1.00mW. This is reproducable, the easiest way is to do issue a TAP TUNE twice and observe the outgoing power and power setting of the K3. Note: This seems to happen *only* if tuning power is set to a fixed value in the Config Menu, and not if Tune Power is set to use current power level for TUNE. Anyone can confirm this?

[Elecraft] K3 #850 is alive
Well K3 #850 is alive and well. Only two problems, KBPF3 filter PCB had L18 snapped off and one lead was cut. So I unsoldered the remaining lead, rewound it, resoldered it to the board, and installed the board at the same time as the KPA3. The other problem was a small scratch on the bottom back cover, which I am sure they will replace. I am not worried about that at all. All the stuff I was worried about like Anderson Power Pole plugs, rattling headphone washers, turned out to be no big deal. Yes I had to redo some steps if I wasn't looking ahead. As I was assembling the front panel I notice their was some room that would cause the headphone washer to rattle, however if you gently push in on the front panel while tightening up the headphone nut with my fingers it took up all the slack. This pressure keeps the headphone nut from backing out. It took me a day to build the rig, a day to finish up the loose ends and do the cals, install the PA, redo the BPF toriod. I took my time and enjoyed the experience over the weekend while attending to call outs from work. I sent one email to Elecraft tech support today about the KBPF3's toriod, not really expecting a reply until Monday. WoW right in the middle of all this software upgrade stuff, I got an email from Wayne. Thanks Wayne for taking the time to answer my questions on how to get L18 going again. First contact as a QRP rig was KA8CPO on 40m CW, second contact was with G3LNP on 40m SSB running 100 watts into my inverted Delta loop. The K3 is a very good experience so far! Order it on 11/27/07 Estimated delivery mid February Got Katigram on 04/25/08 Received it on 05/0208 I almost want to sell it and order up another one. Building and messing with this little rig a ton of fun!

[Elecraft] Hanging on to your K3
As the world gets ever more populated by the K3 there must come a time when we see a message here reporting K3 s/n *** has been stolen - fingers crossed it won't be K3 145. It occurred to me that being software driven, it should be possible to password protect the K3 in such a way to prevent it starting up until a code or PIN has been entered at the keypad; once this feature became known amongst the low-life such individuals may think twice about lifting a radio that could well be unusable without a great deal of hassle. I'm not thinking about a permanent feature here, more something that can be invoked if for instance you're going away for a while or leaving the radio overnight at a contest field day site etc. Ofcourse this would have implications; for instance doing a forced software upload would presumably overwrite any previously set protection. This would I assume involve putting a layer of security in the downloader to allow access only if you know the name of your mother or pet vulture, favourite war criminal etc, etc but this would also solve the inevitable problems when someone sets the security and then forgets the password.. The point is that anything along these lines shouldn't add too much work either for the user or the folk at Aptos so wonder what, if anything, others think about this idea/request? Sensible suggestions only - I've already had my imagination going overactive and thinking about hidden micro-transponders buried deep in the bowels of the K3 which would emit a GPS traceable signal after 3 unsuccessful log on attempts, coupled with a hidden nozzle that would spray an oil based, infra-red dye over the room and occupants and which would show up on the next update of Google Earth; and if the security was cracked, an embedded code would accompany any signals radiated from the radio which will cause CW Skimmer to alternately flash the user's callsign and *STOLEN* in red letters! 73, Stewart Rolfe, GW0ETF (K3 - 145) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3: Loss of rx signal
Rick, In one way I am sorry to hear that you have a problem with occasional loss of RX after TX, however I am pleased that I am now not the only one to report this problem ! I was hoping that the new F/W releases would rid my K3 of this annoying phenomenon, but that did not happen... I have a sequence which I can use to reproduce the loss of RX, and you might like to try it. POWER 80m LSB 3780 NOR LO CUT=0.15 SAV ALT1 NOR TX ON/OFF ALT1 TX ON/OFF Receive may be dead at this point If not continue with Select USB ALT1 TX ON/OFF Receive dead Of course Y.M.M.V. 73 Stewart G3RXQ On Sun, 4 May 2008 20:51:52 -0700 (PDT), AI1V wrote: When running some CW contacts on 40m, I had the unpleasant experience of having the rx go almost totally dead (very low noise level - no signals) immediately after calling a station. Nothing seemed to recover it so I power cycled the radio in time to hear the other station send ..--.. This happened a couple more times. I hadn't notice this happening before. The only new thing I had recently tried was the ALT1/ALT2 filter settings (pretty cool feature). While it is somewhat unpredictable, the phenomenon appears to be strongly correlated with the use of this feature. I have also found that I can recover from the dead rx condition by tweaking the shift or sometimes the width, but sometimes that doesn't work and I need to power cycle. Since then I've stopped using ALT1/ALT2 and haven't had it recur. Note: this problem appears in the new firmware as well as the last revision. On a possibly related note - I was running the hi and low power tx gain cal procedure after updating the firmware. By mistake I spun the width knob instead of the pwr knob to adjust the power. At some point the filter setup got quite hosed - the width display showed around 4 khz, but the passband display was at minimum width. The next time I tried keying (holding tune) I got the nefarious ERR TXF message! I also noticed that the noise level on the rx was way down (I was connected to a dummy load) from where it was earlier. Power cycling the radio brought everything back to normal and I completed the cal. It appears that something is whacking filter parameters in the DSP - or at least that's what it's acting like. I've reported this to support at elecraft. Nevertheless, the radio kicks butt. The mojo is alive and well - worked 18 states this weekend including the west coast on 40CW loading my rain gutter through an SGC tuner!

I don't understand the question; it seems to me to be a matter of physics. A roofing filter is needed to suppress the image response at the final (DSP) IF. True AM detection requires a bandwidth of twice the highest modulation frequency. By full AM I presume you mean medium wave AM (9kHz channels in Europe, or shortwave AM that uses more than one channel, e.g. 5kHz maximum modulation frequency, so you need a 10kHz bandwidth. The only filter available from Elecraft that has at least 10kHz bandwidth is the FM one, and you therefore need that if you want audio beyond about 2.5kHz on AM. You need an additional filter for any true AM detection with a sensible bandwidth. Not having a filter at all is not an option, becuause of the image response. -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

hi Wayne, On 4 May 2008 at 11:48, wayne burdick wrote: Will TX EQ be made mode and/or input dependent? Setting TX EQ for voice screws up the audio response for digital mode (AFSK A and DATA A) operation. The same is true for RX EQ. I believe both RX and TX EQ are bypassed in DATA modes.

I have two different micophones, one needs heavy TX EQ correction, the other one is good with neutral settings. Is it possible to store a profile for this? Settings per input would not help in my case, because I connect both microphones on the rear connector. You will ask, why do I use a different microphone?

Re: [Elecraft] K3 FIRMWARE UPDATE: MCU 1.87, DSP 1.69 (Finally!)
Joe Subich, W4TV wrote: wider than necessary. With the FM filter, the 4.2 KHz high cut is less than the 10 KHZ of IF bandwidth. Why is the IF bandwidth and audio response excessively restricted with the FM filter? It should be possible to achieve at least 12 KHz of IF bandwidth and 6 KHz or more of audio bandwidth depending on the filter skirts. FM bandwidth is a complicated issue, but I believe that, to a first approximation, you can add the peak audio frequency to the peak deviation and then double it for deviation the other way and the other sideband. This covers the dominant sideband frequencies, but actual sidebands are infinite. The most common VHF deviation is +/-2.5kHz. For communications quality audio, that gives a total bandwidth of about 10.6kHz. I'm not sure how Elecraft define deviation. Maybe they define it as peak to peak, i.e. +/1.5kHz, in which case they might get 3.5kHz maximum safe audo frequency in 10kHz. They probably can't go much above 10kHz, because they need to be compatible with 12.5kHz channeling on VHF, or even 10kHz channeling on European CB and PMR 446. Of course, for lower instantaneous peak deviations, one could get more distortion free bandwidth. I would guess that communications FM devices are designed for communication type RF bandwidths, however it is possible that cheap, or even most, devices don't explicitly limit the audio bandwidth, and simply rely on their being little audio power at high enough frequencies to suffer distortion as a result of IF bandwidth limits. The important points are that the required bandwidth for FM is rather more than twice the maximum audio frequency and that FM communications equipment, whilst maybe not designed to police audio bandwidth, isn't particularly designed for wide bandwidths. -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3:VSWR meter readings?
Anyone else observe this on their K3? I terminate my K3 in a perfect dummy load. I then repeatedly test under SSB voice, then without reason it appears as if the K3;s VSWR meter spikes upwards to a higher reading. It seems to do it on every 4th or 5th voice peak. It seems to settle down back to where it should be, then it mysteriously shoots up. Is this normal or is it just the sampling thats slow or something like that? I initially thought it was a faulty cable or dummy load, however I can make the same observation on all my other microwave dummy loads. I checked all my cables, and they are all in fine condition. The VSWR on the loads are as perfect as they can be. I did redo my calibration at all power levels and thats all fine. There is no observable power drop on the scope and the peak reading wattmeter. Under constant carrier conditions its perfect and does not move. I just don't know what to make of this observation. Initially when I was driving the AMP i thought it might have been a tuned input or RF problem, however the dummy load has confirmed that this issue exists independently without the amplifier. 73 Craig VK3HE Be a better friend, newshound, and know-it-all with Yahoo!

Re: [Elecraft] Bass in audio is good
If I could make my K3 sound like its using a Heil HC4 cartridge I would be happy. The Heil HC4 audio sound is ESSB for me! Maybe at sometime in the future transmitting through the 2.1khz filter on SSB will be made possible. A further refinement of carrier point adjustment combined with an adjustable bandpass filter for the TX audio might be another option. It always strikes me how good commercial SSB operators on the marine and aeronautical HF bands sound. Their radios have a precise frequency roll off thats defined in their standards. This standardization produces good outcomes. Regardless of what brand of Aircraft headset you use, you always end up sounding the same on any aircraft HF radio. I think its an ideal that we hams should strive for, this plus clear communications quality audio. 73 Craig VK3HE --- G4ILO [EMAIL PROTECTED] wrote: Mike Scott-7 wrote: I am surprised to hear that people don't like the extra bandwidth in the audio response in the K3.

[Elecraft] MCU 1.88 / DSP 1.70
Wayne and Team, Many thanks for your sterling efforts on the latest firmware. After sorting out an upload problem the end result is a radio which as some might say in |England is cooking with Gas ! I can't comment the number of changes made to modes such as AM, FM and Data which are not my primary interest, but the ones that effect CW and SSB are great. The SSB transmit performance now seems about optimal, with the COMP and ALC working as they should. There are, however more artifacts when using Monitor on SSB. In addition I also appreciate the increased range of the Wattmeter HP settings. On the receive side the DSP filter setting appear to be more stable with band change etc, but I still have the intermittent RX loss after TX. All in all a great job, keep up the good work... 73 Stewart G3RXQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

That extra frequency response takes away from the spectrum available for our fellow Amateurs. Hold that thought Don't even get me started on that ESSB stuff...and why is AM even LEGAL anymore, anyway? It's legal for two reasons: 1) A considerable number of hams like it and use it. 2) No one has come up with a proposal to ban it that hasn't generated overwhelming opposition from the amateur community. Ban AM (particularly from the HF amateur bands) proposals have popped up from time to time since before I became a ham 40 years ago. Always the same basic reason: AM is too wide. Now about tak[ing] away from the spectrum available for our fellow Amateurs - if using the minimum amount of spectrum is the issue, why are any modes wider than a few hundred Hz allowed?

It occurred to me that being software driven, it should be possible to password protect the K3 in such a way to prevent it starting up until a code or PIN has been entered at the keypad; once this feature became known amongst the low-life such individuals may think twice about lifting a radio that could well be unusable without a great deal of hassle. I'm not thinking about a permanent feature here, more something that can be invoked if for instance you're going away for a while or leaving the radio overnight at a contest field day site etc. Ofcourse this would have implications; for instance doing a forced software upload would presumably overwrite any previously set protection. This would I assume involve putting a layer of security in the downloader to allow access only if you know the name of your mother or pet vulture, favourite war criminal etc, etc but this would also solve the inevitable problems when someone sets the security and then forgets the password.. The point is that anything along these lines shouldn't add too much work either for the user or the folk at Aptos so wonder what, if anything, others think about this idea/request? Sensible suggestions only - I've already had my imagination going overactive and thinking about hidden micro-transponders buried deep in the bowels of the K3 which would emit a GPS traceable signal after 3 unsuccessful log on attempts, coupled with a hidden nozzle that would spray an oil based, infra-red dye over the room and occupants and which would show up on the next update of Google Earth; and if the security was cracked, an embedded code would accompany any signals radiated from the radio which will cause CW Skimmer to alternately flash the user's callsign and *STOLEN* in red letters! 73, Stewart Rolfe, GW0ETF (K3 - 145) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

... I sure wouldn't transmit with it, though. It's hugely wide, offering no attenuation of unwanted mixer products. If the filter is too wide, then poor 15 kHz image rejection, aliasing and other unwanted things might happen in Rx.

My FM measurements were as follows: Frequency was 52.525, did not check 10 meters. 12Db SINAD .47uV -113.4dBm Looses squelch (13) takes .79uV -109.0dBm to break Squelch closes at .33uV -116.5dBm Max modulation acceptance 4.90kHz TX CTCSS deviation .3kHz (at 114.8Hz) Maximum mic deviation 2.0kHz (at 1000 Hz mod frequency) Max overall deviation 2.29kHz (above two tones) Here are the issues. The TX deviation and RX mod acceptance are for narrowband operations. We need the CTCSS to be around .6kHz deviation and mic audio around 4.2kHz or so. Maximum overall deviation should not exceed 5kHz. In the US we are still wideband on these frequencies, in both commercial and amateur service, emission designator 20KOF3E. We need more deviation to sound good here in the US. That said, the recovered TX audio waveform looks great! With mic gain turned up all the way with the Elecraft mic, there was no distortion at all on the mod scope. Looked really nice, better than a $14k Motorola Quantar. Very nice modulation. It also simply takes too much signal to break squelch. Loose squelch should be able to break below the 12dB SINAD point. So, please more TX audio, or a way to select wide/narrow if narrow is needed elsewhere in the world, and better squelch action. So, for now, still on the MASTR II for 6 meters... 73 Josh K6ZRX ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Low SSB Output
Wayne, Currently with the newly released firmware it still takes about 60 watts to drive my Alpha 99 to 1 KW (not 1.5KW) on SSB. Twenty eight watts is all that is necessary on my Omni VII to drive my amp to 1 KW on SSB. Twenty eight watts on the K3 delivers approximately 400 watts SSB on the amp. It is possible to increase SSB output somewhat by turning in CMP, but that is not the answer and should not be necessary. I have redone the 5 watt and 50 watt calibration on all bands, and I do not see any significant change. These measurements were made with PowerMaster and LP-100 peak reading meters. Thank you in advance for addressing this problem and providing a solution in upcoming firmware.

Re: [Elecraft] K3 FM filter required for full AM receive width
Sounds good for SWL. Only downside (a minor one, IMO) is that you might get response from images 30 KHz away. How much weaker is a signal when you tune to its image 30 KHz up/down?

The DSP hasn't suffered at all. Maybe with more antenna gain one might see some overload from nearby signals, but not with my modest wire. I sure wouldn't transmit with it, though.

Re: [Elecraft] K3 FM filter required for full AM receive width
Blast ! you got there before me Dave. I have been modeling some suitable LC filters, but as you say they are a bit wide for transmit. However looking back in my log shows that I haven't had an AM QSO for 10's of years, so it's unlikely I will have one now. :-) 73 Stewart G3RXQ I had plenty of time while waiting for #605 to arrive, so I played around with designs on Elsie. I had a filter tested and rough tuned when the radio came. I don't think I'd want to transmit on AM in our neighborhood anyway. I'd surely come in loud and clear on some device in one of the nearby houses. At least no one can identify you on SSB or CW. Hi. AM's better for a countryside QTH. And thanks, Lyle. I was a bit concerned, but I can rock the width back and forth at the point where it changes roofing filters and never tell any difference. But I seldom see a signal much over S9. Maybe it'd be worse with stronger signals. Dave W5DHM ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K3 Firmware Download Problems. Hopefully solved.
Could be a ground loop problem. At the factory we have had trouble with ground loops upsetting RS232 communication between the device under test and the test controller PC... and are careful about our AC mains power arrangements. We try to keep all AC power cords for test gear, PC, etc. on the station plugged into a common power strip. Sometimes optical isolation of RS232 paths is needed for really complicated configurations, where RS232 and USB paths exist both between the controller PC and the test fixture (which has embedded microcontroller) and between the test fixture and the DUT.

There really is no problem. A SSB transmitter is just a linear translator that moves your baseband signal (audio in this case) up into the RF spectrum where you want it. When you mix to translate the signal somehow you need to get rid of the image. That means either filtering it out (filter-type SSB generator) or cancel it out (I/Q type SSB generator). Regardless, it doesn't matter whether you provide the bandwidth shaping at baseband or after your first mixer. DSP at baseband, DSP at the first IF, or a crystal filter at first IF or second IF doesn't matter. Any will solve the problem for you. I think Elecraft has already thought this out.

[Elecraft] Knob shaft and pot issues
My kit K3 #818 came with the shafts on the four small dual function knobs lose and the associated pots feeling like they were gritty when turned. Sure not as smooth and nice as my ICOM 746! Wonder how many #800 units experienced this problem or is it just me? The lose shafts and gritty feeling when turned reminds me of cheap volume controls on a Chinese radio. And how many have experienced a DOA KSYN3 (synthesizer) board in your kit? In addition, how many of you have experienced missing hardware in your kit making it difficult to complete? I sure would hate to be living overseas, missing US nuts and screws, and waiting for the next boat to arrive with needed parts.

Re: [Elecraft] Bass in audio is good
I don't think there is any doubt that Elecraft will not satisfy everybody until the transmit bandwidth is made fully customizable, just like the receiver. I understand that this is also Elecraft's intention. It would seem to make sense to have a CONFIG option that works just like the hi/lo cut for the receiver. With suitable limits for the settings there would be no need for a special ESSB mode. In my book this ought to be relatively high on the priority list, just following straightening out the peak power issues. We already have a world class receiver here, but a little distance to go for a world class clean, powerful transmitter.

[Elecraft] Problems after downloading latest firmware
After downloading 1.88/1.70 firmware, I have had problems. First, I noticed that the receiver came and went on 40M. Then, I switched to 20M and noticed aERR PL1 message and found that 20M receive was also acting strange in the same way. I looked up the ERR PL1 code in troubleshooting and found that the VCO voltage was out of range. So I went into CONFIG: VCO MD and turned to CAL. K3 went through a CAL sequence. Now I have a E 5 ERR VCO message. Where do I go from here to bring my K3 back to life?

[Elecraft] CW to DATA with paddle
Hi guys, today I tried to use my paddle trasmitting in FSK mode as mentioned on the manual at page 32. The TX and RX decode work very well but I found trouble using IM (immediatly exit) or BT (extented timeout). Pratically speaking the above two command don't work ... after write some words the K3 remain in a data idle state for about 4 seconds and after switch to RX mode. The manual said: To cut short the idle transmit period and exit to receive mode, send ..-- (IMmediately exit). This character is not transmitted as data. But in the reality the IM is trasmitted and the K3 continue the idle for 4 seconds. Some of you have tested this feature ? Maybe I'm doing some wrong ?

RE: [Elecraft] Bass in audio is good
Most HF users want AM and ESSB (occupied bandwidth greater than required for communications quality - 2.6 to 2.8 KHz) banned. Unfortunately, certain special interest groups continue to drive the debate. Hi. There are also a lot of radio amateurs that are concerned about the fact that such restrictions in bandwidth will harm the experimenting part and freedom within amateur radio. Radio amateurs has always been experimenting with different microphones etc. trying to make it sound as good as possible. That is a part of what amateur radio is all about (for some). Implementing strict commercial bandwidth limitations within amateur radio is not a good idea. My view is that as long as we try to make our transmitted signals as clean and splatter-free as possible there should be no problems. When i tune across the bands I see a lot of distorted splatter stations on the spectrum scope on my IC-756pro3, especially on 20m. This is because a lot of radio amateurs use way too much microphone gain (high ALC-action) and/or compression/processing resulting in very wide occupied transmitter bandwidth. This is also consistent with the findings of SM5BSZ, Leif Asbrink. Check his articles here: http://www.nitehawk.com/sm5bsz/dynrange/alc.htm http://www.nabble.com/file/p17066871/russian%2Bstation%2Bsplatter%2B1.jpg wide splatter station on 20m My experience is that all these splatter stations are a lot bigger problem than if someone transmits with 3,0kHz or 4,0kHz in SSB. If one shall focus on bandwidth, one must go for the area where something should be done. Maybe a lot more education is needed for new radio amateurs (during licensing) regarding ALC-settings and checking transmitted signals on a spectrum scope to avoid splatter. Some improvements has been done in recent years since many radios now uses Digital Phase Shift Network modulation in SSB (DPSN). This also gives better opposite sideband suppression. The transmitted signals are more brick wall than on some older equiptment I think. Going from 2,8kHz to 4,0kHz TX bandwidth on the Omni VII does not create a very wide signal as long as it is clean and not distorted. Too much ALC-action will create splatter regardless of IF-filter bandwidth. http://www.nabble.com/file/p17066871/Omni%2BVII%2Bwith%2B4kHz.jpg the Omni VII with 4kHz SSB TX There are also facts like some radio amateurs have problems with hearing loss, cutting away the audio to a narrow range (200-2800Hz) will make it difficult to read for some people. The area between 100Hz and 4kHz are the most important for the human ear. This can be confirmed by several scientists working with speech intelligibility research : http://www.polycom.com/common/documents/whitepapers/effect_of_bandwidth_on_speech_intelligibility_2.pdf That is why I hope such bandwidth limitations within amateur radio never will be implemented.

Re: [Elecraft] Bass in audio is good
I am surprised to hear that people don't like the extra bandwidth in the audio response in the K3. For me I have been reluctant to check into a regular rag chew net until I could have some extra low frequency response. I knew that the K3 wouldn't measure up and I didn't want the K3 to be seen in a poor light. Yes I am quite familiar that this is the opposite of good dx performance but these guys don't care about dx at all. They care about comfortable listening. I of course care about dx when I want it and rag chew when I want it. Now I can have both. AM sounds so much fuller now also. I wouldn't want it any other way. Mike Scott AE6WA Tarzana, CA K3/100 SN508 - Hi Mike! I agree with you. I also like the more full audio and I really would hate to see the K3 restricted in hardware or software. Adding a SSB TX bandwidth menu for adjusting this to each users preferences would be fine: 2400 Hz : 300 - 2700 Hz 2600 Hz : 200 - 2800 Hz (default ?) 2800 Hz : 200 - 3000 Hz 3000 Hz : 100 - 3100 Hz (requires 6kHz IF-filter) 3500 Hz : 70 - 3570 Hz (requires 6kHz IF-filter) 4000 Hz : 50 - 4050 Hz (requires 6kHz IF-filter) One can also use a microphone with low cut (the Kenwood MC-90 is great and fits directly on the K3 without re-soldering the 8-pin connector). This one has a low cut with 2 positions, and it has a great audio response for SSB. It is a 250 ohm dynamic microphone with two replaceable microphone heads. For ragchew on a quiet band it is nice to have some more low end and bandwidth.

[Elecraft] K3 - Roofing filter for SWLing
I read, with interest, the discussion about the K3's inability to copy (or perhaps a better way to say it is to reproduce the audio of) shortwave broadcast stations well without a wide FM filter. I just wondered if there is not, or could not be made, a provision to have no roofing filter for someone who wants to listen to shortwave. I haven't done a lot of shortwave listening but is there actually even a need to have the selectivity benefits of a roofing filter for SWLing? Perhaps there is. I am still awaiting my K3 so I ask this as an anxious observer, but I do have the extra bandpass filters as part of my order. Since receivers for years did not have roofing filters, it's obvious that some receivers can operate without one. This would just let the DSP provide the necessary selectivity. The K3 may not have, or want, that ability. I realize that asking for a super-deluxe receiver to be able to remove a roofing filter is a bit like buying a Rolls Royce without the engine and replacing the engine with a riding lawnmower engine. Just a curious question... while I impatiently wait.

Re: [Elecraft] Perfect K3 Speaker
Hi Bruce, For communications bandwidths, a sturdy 4-ohm, 3 or 4 diameter mobile speaker (non-powered) does a great job. For a bit more fidelity and to take advantage of the K3's stereo speaker outputs, I use a pair of good quality bookshelf-style speakers (again, non-powered). Right now I'm using Best Buy's Insignia, 4-inch, 3-way surround speakers, which sound quite good, although they're 8 ohms rather than 4 so the available per-channel peak power will be lower. They're about 4W x 8H. I had been using just a single speaker, but having two allows me to get L/R separation of the main and subreceivers, as well as take advantage of the K3's AFX simulated stereo mode. 73, Wayne N6KR Hi. I am awaiting my K3 to be ready including all the options I ordered (DVR etc.). I am planning on connecting two small bookshelf speakers (Proson Sat 51RR) who have excellent audio. I am currently using these on my IC-756pro3, and they sound a lot better than any amateur radio speaker. If one really wants to reveal the details in the received audio I can recommend the AKG HSD-271 headset (with dynamic microphone). These are outstanding in every way, and sounds incredibly clear and neutral. The electret mic version of these are the HSC-271.

[Elecraft] Good Amateur Practice (WAS: Bass in audio is good)
Most HF users want AM and ESSB (occupied bandwidth greater than required for communications quality - 2.6 to 2.8 KHz) banned. Unfortunately, certain special interest groups continue to drive the debate. Yes, and they're called Hams or Amateur Radio Operators, too. The same debate was just as hotly argued years ago. Then it was most Hams wanting those absurdly spectrum wasting phone or voice transmissions banned. CW was much more efficient. Then, after AM phone was well-established, there was a similar movement to ban the absurdly difficult to tune and interference-prone single sideband transmissions from the Ham bands. Fortunately, all of those failed and Amateur Radio remains an experimenter's haven. Good Amateur Practice does not mean the best signal commercially-designed equipment can produce. Good Amateur Practice has always come down to a value judgment considering the equipment and mode being used and the experience and skill of the builder/designer/operator. I hope it always remains so. Indeed, for many of us, experimenting, tinkering and learning about equipment and modes, both old and new, is the reason we're Hams. For me, that will always be so.

[Elecraft] K3 Firmware 1.88
I am happy to say that firmware v.1.88 appears to have corrected my low output on SSB. I went to CONFIG: TXG VCE [T] and dialed in 1.5 dB.

Re: [Elecraft] K3 FM filter required for full AM receive width
Jerry Flanders wrote: for SWL. Only downside (a minor one, IMO) is that you might get response from images 30 KHz away. How much weaker is a signal when you tune to its image 30 KHz up/down? Less than 30kHz. The whole point of the exercise is to use wide filters, so, assuming that the interference is from a carrier and appears in the demodulated audio, the image can be 25 (5kHz audio) to 20kHz (10kHz audio) away from the carrier (20 and 10kHz from the passband edge). If the interference is from an audio component at the extreme of the bandwidth and the transmit is the same as the receive bandwidth, the carrier can be 20 to 10kHz away (although in the latter case would have other problems). In practice, I would expect the carrier to get past a weak filter better than an extreme sideband frequency. Note this means that if the signals are trying to reproduce audio up to 10kHz, the adjacent channel will be an issue. -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Is it just me or ......
No, it's not just you. Count me in as well. I am in the same boat as you. I don't care that much about AM and FM although I do ultimately want it, but I do want SSB to work at full power. I am also worried that the extension down to 200Hz is just waisting power that contributes very little to getting heard. If anything I would want the total transmit bandwidth to be reduced to 2400Hz (300-2700Hz) which is pretty well the standard filter bandwidth for a fixed no-DSP transceiver with just one filter. But as I said earlier today, to please everybody these things need to be configurable. And this got to be the top priority at Elecraft.

Re: [Elecraft] SSB output with new firmware
Ian et al, I did the same thing but found out later that my SSB audio sounded a little gravelly as if I was overdriving early stages of the mic audio amplifier. This was true even with no bars of ALC showing and with both my MH2 mic and another backup microphone. After a lot of tests and trials I finally discovered the problem disappeared when I set CONFIG.TXG VCE back to 0 db which seemed to make little difference in my ssb power output anyway. So 0 db is where I shall leave that setting. Don K7FJ Hi all, I installed the latest firmware this morning but have only just got around to testing. To be sure, I reset the radio and started the at the beginning, calibration and all. Having done all of that I set the CONFIG:TXG VCE menu item to 3.0 dB. The rig now almost gets to the set power on voice peaks. I would like a little more but it is close enough and *way* better than the 50% I was getting previously.

[Elecraft] K3 Single Band SWR problem
My first real problem (or operator error?) with K3 SN 608 just occurred. I got on 20 CW with my usual antenna (a resonant dipole) and the K3 is showing a 2:1 SWR and folding back power. I bypass the tuner with this antenna since its SWR is in the 1.2 to 1.3 range. My external SWR meter shows the usual 1.3. If I engage the K3 tuner it will tune to a 1:1 indication on the K3 meter and register the requested output power, but the actual output power measured externally is in the range of 70 to 80 W for 100W on the K3 meter. Next I tried a known good dummy load and the K3 acts the same with it - indicates a 2 to 1 SWR. Interestingly, it works fine with the dummy load on all the other bands (shows 1.0 to 1 SWR) except 20. It has worked fine before on 20 with this same antenna and as far as I know nothing has changed. I'm running firmware version 1.78. Will welcome any ideas or suggestions Thanks ...

RE: [Elecraft] Bass in audio is good
'Information rate' is I suppose the let-out. Information rate is not a let out in analog voice. I would have thought that the use of ESSB would come close to breaking the rules on Emission Standards as imposed by some regulators, e.g. FCC Amateur Rules section 97.307 which says in part 'No amateur station transmission shall occupy more bandwidth than necessary for the information rate and emission type being transmitted, in accordance with good amateur practice'. This is key and should be enforced. Many years ago Bell Labs (and others) proved rather thoroughly that 2.4 to 2.6 KHz was more than adequately for communications purposes. Their tests were specifically in relation to toll grade audio for long distance telephony. The FCC rules specifically required a maximum bandwidth of 2.6 KHz on the US 60 meter channels. That should provide a strong example of what FCC and NTIA consider to be the maximum bandwidth necessary for single sideband operation in amateur allocations. Most amateur transceivers use 2.4 KHz bandwidth filters for SSB generation - even cascaded 2.4 KHz filters with an effective bandwidth in the 2.2 KHz range. The default SSB transmit bandwidth for the K3 should be 300 - 2900 Hz or 200 - 2800 Hz in order to not be excessively wide and meet the FCC regulations for use on the US 60 meter allocation. 73, ...

[Elecraft] K3 ERR VCO after loading new firmware and doing VCO CAL
If you see ERR VCO on VFO B after attempting a VCO CAL, it could indicate that the new firmware load process did not complete. Specifically, some data needed by the K3's synthesizer may be missing. It is stored in something called the FPF (front panel flash memory). If you see these errors -- or if you hear anything odd when tuning the VFO, such as disappearing background noise -- you should try re-loading the FPF data. To do this: 1. Make sure you're running K3 Utility version 1.1.4.1 or later (do Help/About K3 Utility). 2. Try re-loading everything a second time by clicking on send all new firmware to K3. 3. If you don't see any error messages after the load, try the VCO CAL again. If that doesn't work: 1. In K3 Utility's View menu, turn on Advanced mode. 2. Click the Load checkbox for the FPF component (right after MCU). 3. Click on Send Checked Items to K3. (If this button is grayed out, try turning Advanced mode off and back on.) 4. Turn Advanced mode back off. 5. Try VCO CAL again. If this fails, please contact [EMAIL PROTECTED] and include in the e-mail the following: - your K3 serial number - the present firmware revisions loaded into the K3 (as indicated by either K3 Utility or from the K3's CONFIG:FW REVS menu entry) - the entire Activity Log text from K3 Utility (you can drag the mouse over the entire contents, starting at the top and going down and to the right, then do ctrl-A to copy it, then paste it into the e-mail) tnx Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] VFO AB
Julian and All, This kind of thing emphasizes the value of something I suggested previously. I think the manual should be downloadable in Word, or some equivalent, and then updated by just revising the individual pages. A revision page would be designated by the page number plus an appropriate letter or decimal follower, like 43.1 or 43.2, etc. You would only have to download the overall manual once, and then just download revision pages. If you put the manual in a loose leaf binder, revisions are easy to insert. This method is used extensively in professional reference material. Manual updates can also be indexed and dated (as should revision pages). If we are going to have a radio that is continuously upgradeable, I think the manual should similarly be upgradeable in some fashion like this. That way you don't have to be constantly looking for errata sheets which might alter the procedure you are looking for. Just my humble opinion!

re: [Elecraft] K3 - Latest firmware (last nite) FM test results, not good for U.S.

I am certain that these problems will be addressed in a subsequent firmware update... and hope it will be soon. I've tried some of the other enhancements... I love the ability to send CW while in SSB mode with an offset that will allow a station zero beat (on ssb) to hear the CW. Thanks guys, for adding this feature... and for all the tremendous work on firmware to enhance and improve the K3 experience. 73, Joe - W1AIU ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Listen for GM4ESD on the 40m Elecraft SSB net tonight
Gents, Come join the net and listen for Geoff. I have thunderous sky here, but I'll do my best (?) Windy KM5Q K3 #674 Good evening Windy, 40m almost woke up here last night, good contacts into Chile etc. If I can stay awake I shall be listening / calling on 7.190 MHz +- tomorrw morning at 0100 UTC (0200 local time). I will have to use my homebrew receiver as my K2/100's receiver cannot cope with the BC station at 7.190 MHz, but will use the K2/100's transmitter to make things 'legal'!! 73, Geoff GM4ESD ELECRAFT SSB NET MONDAY THURSDAY EVENINGS 0100 UTC on 7.190 MHz That's evenings local time in the Americas.

[Elecraft] Bass in audio is good
Hi Joe, I don't run ESSB here BUT...I prefer the revised K3 firmware as it now is. Apparently many others feel the same based on responses in this thread. You are certainly entitled to your opinion and the rest of us to ours as well. 73 de N1LQ-Dave ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Manuals
In a recent message, David Yarnes [EMAIL PROTECTED] writes I think the manual should be downloadable in Word, Gosh, I sincerely hope not, David; I for one do not wish to have to start installing another Microsoft product. How about Corel WordPerfect? No! Let's stick with Adobe Acrobat Portable Document Files. Most people have Acrobat on their PC and can print out in whatever size of paper they choose. Just my humble opinion! Mine too. 73 -- David G4DMP Leeds, England, UK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] Bass in audio is good
In a message dated 5/5/08 5:14:48 PM Eastern Daylight Time, [EMAIL PROTECTED] writes: Many years ago Bell Labs (and others) proved rather thoroughly that 2.4 to 2.6 KHz was more than adequately for communications purposes. Their tests were specifically in relation to toll grade audio for long distance telephony. Which is *not* amateur radio communication! Things like QRM, QRN and selective fading are not usually encountered in landline telephones. Note also that despite the quality standards, people often have to repeat themselves on the telephone, spell out words and names, etc. The FCC rules specifically required a maximum bandwidth of 2.6 KHz on the US 60 meter channels. That should provide a strong example of what FCC and NTIA consider to be the maximum bandwidth necessary for single sideband operation in amateur allocations. No, they shouldn't. The 60 meter channels are shared with other services. Amateurs are secondary users there, and must conform to the primary user's standards. Most amateur transceivers use 2.4 KHz bandwidth filters for SSB generation - even cascaded 2.4 KHz filters with an effective bandwidth in the 2.2 KHz range. The default SSB transmit bandwidth for the K3 should be 300 - 2900 Hz or 200 - 2800 Hz in order to not be excessively wide and meet the FCC regulations for use on the US 60 meter allocation. Agreed! But that's only on 60 meters. Should we stop using LSB because other services don't generally use it? Should we channelize our bands because that's what other services do? I say there's room for all. 73 de Jim, N2EY ** Wondering what's for Dinner Tonight? Get new twists on family favorites at AOL Food.

[Elecraft] FM test results - not good for U.S.
I'm a retired career two-way radio tech and I'll add a me too to Joe's FM-mode observations below. He's correct. 73!
