Re: [Elecraft] K3 Audio in speaker during transmit.
When I have my rig set for speaker+phones off with the monitor up I can hear myself but it doesn't emit from the speaker. This is how I set EQ settings and what not as it allows me to turn the monitor up louder without producing feedback.

Nevertheless, I hear myself in the speaker during transmit. I have the speaker + phones feature turned off. I thought the speaker should be muted during transmit but it is not. Someone else remarked that the monitor volume should be turned down but I don't understand why that should be necessary if the speaker + phones option has been set to no. I also would like to avoid having to do that because if conditions suddenly turn bad and I need the earphones, it would be a pain to also have to turn the monitor back up.

Re: [Elecraft] Suitable headphones for K3
Hi Jack, I have a Beyer Dynamic DT109 headset.

[Elecraft] Weak audio on 2nd RX
I have installed my KRX3 and have been trying to learn to use it effectively, but seem to have something misadjusted somewhere. When using diversity reception with a beverage on the main RX and a receive 4-Square on the second RX using the BNC input, the audio in my left ear (the Main RX) is much louder than the audio from the right ear. I am not aware of any hearing deficiency in either ear and I have to turn the volume on the second RX up considerably higher than the main RX to have them approach parity. Is this normal? I also see that when I attempt to enable the 2nd RX to work on a different band than the main RX, I cannot set it. Is there still a firmware upgrade required before this feature will become active?

Re: [Elecraft] K3 competition from Icom?
Of course it is competition, in the popularity stakes if not in performance. It may not have as good a receiver performance as the K3 but it looks very good, the receiver is very probably quite good enough for many people and it has a few popular features which are not yet available in the K3 - e.g. the built in spectrum scope, a USB port, more than one antenna output, control for an external ATU. Not everyone feels they need the best possible receiver performance, other issues come into the equation. If the price is good, I expect is will sell well, just like the 756 Pro III it replaces. This does not matter as Elecraft and ICOM are adressing very different markets. It is great to see the major companies producing new radios with higher performance and improved features, it would be awful if this development stopped, so we must not discourage them.

[Elecraft] KX-1 BC interference on 20m
As I have mentioned before, I really enjoyed using the KX-1 on holiday in Europe this year but found that there were several broadcast stations appearing across 20m from about 14.20MHz upwards.

[Elecraft] [K3] Rx/Tx equalization
50 Hz and 100 Hz octave bands are VERY important -- they allow equalization to correct for proximity effect in directional microphones, and to reduce the effects of breath pop. Jim (K9YC), what part of the 50 Hz spectrum will get by a 2.7 KHz roofing filter at any equalization setting? At least on my system I could put 50 Hz at +16 dB gain and 50 Hz will still be down 20 dB. The DSP skirts put it lower. I ask this question because I have been staring at my actual roofing filter plots. So I don't quite understand where you are coming from. Perhaps the devil is in the details and breath-pop energy which would be cut off by the roofing filter/DSP combination is still affecting the transmit-audio gain in deleterious ways. Maybe it is just my lack of understanding of how the K3 works. In this area it is a bit of a black box to me, the price we pay for not soldering.

Re: [Elecraft] KX-1 BC interference on 20m
Stephen - Some of those SW BC stations are pretty strong - as in hundreds of KW. It is possible that what you were hearing is the 2nd harmonic from these stations operating in the 41-meter (7.10 - 7.35 MHz) Shortwave Broadcast (SW BC) band. Given a 100 KW transmitter, with 2nd harmonics 40 dB down from the fundamental (which would be considered reasonably good suppression) is still 10 watts at the 2nd harmonic, or roughly 5 times the output power of a 2-watt KX1. Since the European (ITU Region 1) 40-meter SW BC band starts at 7100 KHz, I think, then it would be normal to hear such signals starting at 14.200 and continuing up in frequency across the rest of the 20 meter band. 100 KW is probably more or less a median power level for SW BC stations, with some running less, and some quite a bit more - as in 500 KW. And, this is real power from the PA. Add to this the fact that some stations get another 10 dB or more from antenna gain in whatever direction they happen to be beaming and we're talking big time competition with amateur signals. Another consideration is that SW BC stations are usually designed to be frequency agile, and so they often have antennas that can be used on multiple frequencies. Such antennas can be efficient radiators of harmonic energy. So, the best hope is to wait for a few more years until the 40 meter broadcasters move above 7300 KHz, which I think is in the works, but I have forgotten just when it is supposed to happen. In any case, the problem you describe will be with us for a few more years. - Jim, KL7CC Stephen Prior wrote: As I have mentioned before, I really enjoyed using the KX-1 on holiday in Europe this year but found that there were several broadcast stations appearing across 20m from about 14.20MHz upwards.

Re: [Elecraft] Heil life
I don't think I will ever buy another Heil headset. My quiet phones plus were cutting out anytime the cable moved. So I took the phones apart and could not believe how cheaply these things were put together. The soldering of the wires to this little PCB looked like they were done by a 5th grader and was the cause of my problem. There was no heat shrink used on any of the bare wires and so when there was movement of the cable exiting the earpiece it was causing a couple wires to short. I resoldered them and used heat shrink and now they're back to working again. Performance wise I love them. They REALLY cut out the noise from my amp and computer.

Re: [Elecraft] KX-1 BC interference on 20m
Given a 100 KW transmitter, with 2nd harmonics 40 dB down from the fundamental (which would be considered reasonably good suppression) is still 10 watts at the 2nd harmonic, I'm not sure about Europe but the Amateur radio *minimum* standard at HF for 1500 watts is about 45dB down for any spurious or harmonic. While there are lower suppression levels at lower power, it is set at a 50 milliwatt maximum limit. The USA commercial BC standard is in the -80dB range, I can't remember the exact amount. I just dealt with that with an AM BC station 100 miles from here that had a spur on 160 meters that was in the -40dBc range. In all cases there is an overriding regulation that says no matter what the level of spurious or harmonic, the unwanted emission cannot cause interference to a licensed service. This doesn't prevent BC stations from violating rules, especially in the USA with the poor enforcement and poor maintenance, but the rules themselves are pretty strict. -40dB would be considered very very poor suppression. 73 Tom ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I don't know first hand, but I understand the scopes on this and the 7700 are not real time. I just don't see the usefullness if it's not. Competition for the K3? I think not. - 73, Greg - AB7R Whidbey Island WA NA-065 On Mon Aug 25 4:38 , DOUGLAS ZWIEBEL sent: http://www.ab4oj.com/icom/ic7600/main.html not in my opinion! de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Weak audio on 2nd RX
Sigismonti Ronald wrote: I have installed my KRX3 and have been trying to learn to use it effectively, but seem to have something misadjusted somewhere. When using diversity reception with a beverage on the main RX and a receive 4-Square on the second RX using the BNC input, the audio in my left ear (the Main RX) is much louder than the audio from the right ear. I am not aware of any hearing deficiency in either ear and I have to turn the volume on the second RX up considerably higher than the main RX to have them approach parity. Is this normal? Hi Sig, If you swap them and the subrx is still down from the main then something is not right. Gain should be quite close. I also see that when I attempt to enable the 2nd RX to work on a different band than the main RX, I cannot set it. Is there still a firmware upgrade required before this feature will become active? There's a configuration parameter called VFO IND which at some point will allow the sub to be on a different band than the main.

Re: [Elecraft] K3 competition from Icom 7700? yes
Of course it is competition ( IC 7700 ), as some will buy it rather than the K3. It is however an apples and oranges comparison... The 7700 has dual watch which is just like the 756PIII, much better than no second receiverbut far far from a full second receiver( it can't split the main dual watch audio, just vary the audio level between the two) still need the 7800 for 2 receivers. The Pro3 is a great piece of product extremely well executed. The Pro3 scope I prefer to the scope on the 7800.maybe the 7700 is different. I use a scope on the K3 now LP-PAN /or SDR-IQ works great.

[Elecraft] Using K2/100 on QRP
I have the K2/100 with the KPA100 and KAT100 mounted in the separate EC2 enclosure. I would like to use the K2/10 in a portable situation independently, leaving the 100 watt components here in the shack. I have no concern with the uncabling part of the operation, but I am wondering if there is some menu item(s) I must reset after getting the K2/10 separated from its high-powered components. This is the first time I have contemplated such operation since obtaining the amp/tuner about 18 months ago, and I can't remember what if anything I did to the menu items to get both boxes working together. I feel sure that this has been done by many folks who can quickly set me on the right path.

A serial port can be interfaced to USB using a readily available and inexpensive adapter, or, as has been pointed out, by installing a PCI serial card in an expansion slot. A USB device can only be interfaced to a PC that has a USB port and drivers for that particular device. Of course, Icom will ensure that the drivers are available today to connect the thing to Windows. But drivers may not be available for other platforms (as was the case with the RigExpert interface I sold because I could not use it under Linux) and they may not be available at all in 25 years time by any OS which is not an unreasonable time for someone to still be using a radio (even if not the original owner.) Whereas you can be pretty damn sure that RS-232 ports will still be around, and there will be adapters to interface them to whatever type of peripheral connector is popular at that time.

On Mon, 25 Aug 2008 07:04:21 -0700, Mike Scott wrote: Jim (K9YC), what part of the 50 Hz spectrum will get by a 2.7 KHz roofing filter at any equalization setting? At least on my system I could put 50 Hz at +16 dB gain and 50 Hz will still be down 20 dB. The DSP skirts put it lower. I ask this question because I have been staring at my actual roofing filter plots. So I don't quite understand where you are coming from. Perhaps the devil is in the details and breath-pop energy which would be cut off by the roofing filter/DSP combination is still affecting the transmit-audio gain in deleterious ways. Maybe it is just my lack of understanding of how the K3 works. In this area it is a bit of a black box to me, the price we pay for not soldering. Hi Mike, You're looking at the total signal path from mic in to RF out, but you're not considering what happens in the audio blocks that precede the transmitter. Good audio processing for communications uses careful equalization to shape the audio response for maximum use of the transmitter bandwidth, as well as compression and peak limiting to bring softer parts of the transmitted speech up to nearly full modulation level. There's also VOX, that looks at the transmit audio and turns the transmitter on when it sees audio. The compressor, limiter, and VOX all look at transmit audio to decide how to do their thing. If your microphone is producing lots of output on low frequency energy, it will cause the compressor and/or limiter to turn down the gain, reducing your modulation. That LF energy can also trigger the VOX prematurely. Yes, the transmit crystal filter imposes some hard limits on the transmitted bandwidth, but all of that is FAR up the signal chain from the audio processing noted above. The audio chain can suffer from these problems, and it can also produce distortion if over driven. Another point -- proximity effect is a LARGE effect when it is present, easily 15-20 dB of LF boost. It's only present in directional mics, but most pro mics suffer from it. If you're using one of those mics, it's easy for breath pops and other LF noise to be 10-20 dB louder than your voice. So your audio gain may be just fine for your transmitted speech, but pops and LF noise may be distortiing in the audio chain. The value of equalization and dynamics processing for ham radio are discussed in an appendix of http://audiosystemsgroup.com/RFI-Ham.pdf. Good audio processing -- equalization and compression/limiting -- can increase your effective talk power by 6-10 dB! That's equivalent to adding a 400W - 1,000W amp to your K3. Broadcasters learned this MANY years ago -- all of them are carefully equalized and processed. 73, Jim Brown K9YC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] [K3] Rx/Tx equalization
Jim: Very interesting discussion. For those of us who are mostly data mode and CW operators and might make a handful of SSB contacts in a good year, how should we go about adjusting the transmit frequency shaping parameters? What do we measure and what do we tweak? At one extreme would be adjust until it sounds good, but that rubs against my analytical side. Looking at the audio output in monitor mode with a spectrum analyzer misses parts of the audio chain ahead of the transceiver. Ultimately, of course, some make it sound good tweaking is necessary, but I'm looking for some numerical guidance. E.g., equalize so that the spectra below 200 Hz is X dB down from midrange peaks or whatever.

Re: [Elecraft] [K3] Rx/Tx equalization
True story related to your comment below ... I worked my way through law school in the 1970's as a transmitter engineer at a 50 KW AM directional station in the Detroit market. The studio was 15 miles from the transmitter, connected by main and backup broadcast quality telephone lines. One afternoon I'm watching the meters and listening to the monitor speaker when I hear a series of beeps, sounds like a string of Morse dots and then the main telco line goes dead. Switch to the backup line and let the Chief Engineer know. A half hour or so later, same thing happens to the backup line, so crossing my fingers, I switched back to the main and it was working. Later that day, the jocks started complaining that the audio sounded muddy. All the guys at the transmitter thought it sounded fine to them. For those who have not worked in this environment, a 50 KW transmitter room is not silent, as it has several multi-horsepower blowers to keep the transmitter cool. And, the monitor speaker was not what one would use for serious audio reference. We then ran a sweep of the lines that night and sure enough, instead of the 15 KHz response the station paid for, the line cut off around 3.5 KHz. Both of them. It turns out that the beeps were the pair identification tones the telco splicers use when working on cables and what they had done was add loading coils to the program lines, converting them to a standard toll grade quality line. That experience taught me my ears are not a precision calibrated instrument and that I should have more faith in spectrum analyzers.

Re: [K3] [Elecraft] Rx/Tx equalization
Bad choice of words - what I was getting at is that you are looking at the composite of the microphone and the transceiver's audio processing. It would be useful to look at each separately. This suggests looking at the microphone individually, into an audio spectrum analyzer and also looking at the transceiver response with a swept tone to understand what is going on in both as well as looking at them with normal speech when connected.

I like what Julian said here and I think he is spot on. I do not think it would take much for the wizards at Elecraft to redesign the KIO3 to include both...RS232 and a USB port. users could swap out one for the other and you have USB port. That is so cool about the K3 and its modular design. Again, the whole issues of drivers come up, but I am sure Elecraft would keep up with it all. But that is another expense to redesign the unit and keep up with all the programming of the USB drivers.

Re: [Elecraft] KX-1 BC interference on 20m
Hi Geoff Well, I left out perhaps the most important info in that I don't have the problem on the same antenna with either the K2 or K3. I have mentioned the knock that the KX-1 received. I have subsequently found that the knock has broken the soldered joints holding both earth pins of the bnc socket- looking at them I'm pretty sure they were dry joints anyway. Having resoldered them, most of the BC qrm has gone, but not all. I have the same effect both here in the UK and in Portugal and France, so it's not a nearby fence in this case :-)) I'm sure that I did not experience the problem when I first had the radio and I am wondering if there are further joints which have been disturbed- my son caught the coax with his legs as he walked past my tent and the radio flew off the table really very quickly! I was pleased to find that it still worked. 73 Stephen G4SJP On 25/08/2008 19:21, Geoffrey Mackenzie-Kennedy [EMAIL PROTECTED] wrote: My thought is that the problem was caused by one or more of the natural spurious responses of the KX-1's receiver, not by some harmonic or spur generated by the BC transmitters themselves.

Re: [Elecraft] K3 competition from Icom?
If you notice, the USB port is fixed there. The whole communications interface area of the K3 can be update, modified, and changed as the rig and firmware grows. Elecraft chose the RS232, as a port that so many folks have used in the past. If you listen to hams (like on this list) think about how many are resistant to change. If they had come out with USB and no serial there would have been a cry from the masses of DOS/Win95/OS2/WinME/Win98 users that they could not use their serial ports. Don't get me wrong, I find USB/Serial adapters annoying, but mine has worked great. I get the Belkin ones that Staples sells, and everything has worked fine for me. I would rather have a USB interface, and possibly an Ethernet interface. But I am very happy to know that I have a rig that is getting firmware updates, and the hardware was developed in such a way, that it has the ability to grow and change, as the technology does.

Re: [Elecraft] K3 competition from Icom?
HI Greg and all, Just to clarify at bit, I wouldn't compare the 7600 as a IC-746 less 2m. The 746 series rigs never had a real time bandscope, but the IC-756 Pro 3 and the 7700 are about as real as it gets. If I was going to compare the 7600, I would compare it to an enhanced Pro 3 or a 100 watt 7700. However that's just my take on it. The larger displays also serve as nice platforms for plain English menus (I've always wonder what they do in other countries?) and make nicer displays for PSK and RTTY if you are not using a computer. I love great radios, but I would rather I have great antennas (I don't) and be a great op (sorry to say I am not!). Now time to fire up the K3 and make some contacts anyway. :-) 73 de jay/w5jay.. I couldn't agree more! This is an IC-746 with a few new features and less 2M. So what? It may be nice for the casual operator not concerned with DXing or contesting and cannot afford their 7700. I don't know first hand, but I understand the scopes on this and the 7700 are not real time. I just don't see the usefullness if it's not. Competition for the K3? I think not. - 73, Greg - AB7R Whidbey Island WA NA-065 On Mon Aug 25 4:38 , DOUGLAS ZWIEBEL sent: http://www.ab4oj.com/icom/ic7600/main.html not in my opinion! de Doug KR2Q ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Hi Stephen, It might help if you could identify the SW stations you're hearing, and find out what frequency they're on. What you could be hearing is a very strong signal on the receiver's image frequency, and the only thing you could do would be to add more selectivity to the front end to attenuate the signal on the image frequency.

[Elecraft] OT- Using two coaxial cables as a balanced feeder
Sorry to take up bandwidth here, but as there are some very knowledgable folk on list I thought I would run this query. I've been playing with a balanced feeder for my quad - DJ4VM driven element cut for 20M. I have 30M reflector. The impedance is very low on 30M and it does not like the 450 ohm line. I got over this by putting a 9:1 step down transformer, which works OK, but I suspect it may be lossy on the other bands where it is not needed. I thought it would be a good idea to make a balanced line from two pieces of RG213 to reduce the ohmic losses of the cable (the run of 450 ohm measures 6 ohms DC) and get a closer chacteristic impedance to the the quad on 30M I made two lengths of RG213 coax with the inner and outer of each cable parralled and the two cables stuck together with insulating tape as a balanced line This did not work at all well for some reason. I have also (as per the RSGB Rad Com Handbook and seen nowhere else) rearranged the cables so that the braids are connected together and grounded with the two inners providing the balanced line. On a small version of the DJ4VM quad as a test antenna, which is only a couple of ohms on 20m, the K2 sounds dead. removing the braid and using the feeder as a long wire brings the signals way up. My query is this. Is there an error in principle in using two pieces of coax as a balanced line, which would imply the handbook is wrong or am I missing something. I did wonder if the braid, used in this manner has a different velocity factor to the inner and whether this could be the problem - or am I trying to do the impossible? I have experienced a related problem in the past when I used a smalll loop antenna on 160M - about 25 ft on each leg, mounted vertically. The botton being about three feet above ground. The design was by Paul G4LNA as can be seen on the link below http://www.geocities.com/g4lna/pages/myant.html Fed with 50 ohm coax through a step down transformer with one side of the secondary going though a series capactor to one side of the loop, the other side of the transformer connected to the return of the loop. This antenna worked very well on 160 - but if fed with 450ohm line through a balanced ATU, did not radiate at all despite a low SWR. Any ideas welcome off list. 73 -- John Petters www.traditional-jazz.com Amateur Radio Station G3YPZ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KX-1 BC interference on 20m
Stephen and Ed, I was thinking along those same lines. On 20 meters, the KX1 LO signal is below the RF signal, so a strong BC station in the 4.1 to 4.3 MHz range could push itself through and be heard on the upper end of the 20 meter band. If you have no stations on that part of the spectrum, you can likely reject the assumption of an image response. The KX1 design faced many challenges in order to stuff all that performance in a small space, so the design is a bit of a compromise. The front end suffers from responses in the presence of strong RF energy just like any other Gilbert cell mixer connected in the receiver front end (with no RF amp stage for isolation). My understanding is that the Gilbert cell mixer can generate 'funny stuff' in the presence of strong RF energy fields like might be found in Europe - in reading EMRFD, I find that Wes Hayward does not even recommend the gilbert cell mixer for use in receivers that will be used on the Eastern side of the US for this very reason. In addition, the DDS does have some spurs that can be mysterious - if the offending signal tunes more quickly than normal signals, you are likely hearing the result of one of the DDS spurs. The KX1 is a good design, but it just is not perfect in all ways. You may be hearing the result of one of these imperfections - OTOH, you *could* have a problem there.

Re: [Elecraft] OT- Using two coaxial cables as a balanced feeder
John, Your pair of 50 ohm coax lines has twice the loss of a single coax line and the characteristic impedance is 100 ohms, so I would expect its loss to be much greater than using the 450 ohm line with no lumped transformers (the feedline itself will act as an impedance transformer, and a quite efficient one at that. Can I suggest that you might use a length of 450 ohm (or better yet open wire line) that is about a quarterwave at 30 meters as a matching section. That will transform the input impedance to something much higher, then run 450 ohm line to the shack. It is not unusual to use 450 ohm ladder line with a widely varying range of antenna impedances. Even when operated at high SWRs, the ladder line (when dry) has a very low loss. If your tuner has a limited range and cannot properly match the feedpoint impedance of the feedline, adding (or subtracting) a length of line to the feeder length can bring it into a range that your tuner can match. I would suggest adding or subtracting in 1/8th wavelength increments until you get it close to the desired range and then go to 1/16th wavelength additions or subtractions. The feedline acts like an impedance transformer when it is operated with an SWR other than 1. 73, Don W3FPR john petters wrote: Sorry to take up bandwidth here, but as there are some very knowledgable folk on list I thought I would run this query. I've been playing with a balanced feeder for my quad - DJ4VM driven element cut for 20M. I have 30M reflector. The impedance is very low on 30M and it does not like the 450 ohm line. I got over this by putting a 9:1 step down transformer, which works OK, but I suspect it may be lossy on the other bands where it is not needed. I thought it would be a good idea to make a balanced line from two pieces of RG213 to reduce the ohmic losses of the cable (the run of 450 ohm measures 6 ohms DC) and get a closer chacteristic impedance to the the quad on 30M I made two lengths of RG213 coax with the inner and outer of each cable parralled and the two cables stuck together with insulating tape as a balanced line This did not work at all well for some reason. I have also (as per the RSGB Rad Com Handbook and seen nowhere else) rearranged the cables so that the braids are connected together and grounded with the two inners providing the balanced line. On a small version of the DJ4VM quad as a test antenna, which is only a couple of ohms on 20m, the K2 sounds dead. removing the braid and using the feeder as a long wire brings the signals way up. My query is this. Is there an error in principle in using two pieces of coax as a balanced line, which would imply the handbook is wrong or am I missing something. I did wonder if the braid, used in this manner has a different velocity factor to the inner and whether this could be the problem - or am I trying to do the impossible? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Being the not-so-proud owner of several pieces of once expensive but now useless junk, I'm somewhat sensitive to future issues that might prevent me from using hardware I purchased. In other words, the DON'T upgrade or else mentality. With the K3, the only potential weak link I see is the K3UpdateUtility. Will it still run on Windows 2018, Mac OS XII 12.2, or Ubuntu Zesty Zebra? If I find a Brand new in box K3 SN 2000 on eBay 10 years from now, will I be able to load firmware version 2.32 on it? I totally understand that manufacturers can't support their devices forever across all possible platforms. But I'd feel better about my purchase if there was a public spec that detailed how to upload firmware files. Next best thing would be if source code to the K3 Update Utility(s) were available. 73 -- Joe On Aug 25, 2008, at 3:26 PM, Doug Faunt N6TQS +1-510-655-8604 wrote: [snip] I resent facing scrapping a perfectly good bit of hardware because of the upgrade or else mentality.

Dave, That Win98SE surely has real serial ports. I strongly suggest that you use one of the real serial ports. IIRC correctly (it has been years), but the USB support in Win98SE was flaky at best - the situation did not get much better until Win2k, and by then Win98 was fading into the background - even the 'SE' version of Win98 was a patch at best, but the real serial ports worked just fine. You can unplug one of your existing serial connections long enough to load the new firmware on your K3 and then revert to the normal use of that port.

Re: [Elecraft]RS-232 and USB with Elecraft.
I'd bet dollars to donuts that if this board was redesigned that what would happen is that an FTDI chip (or similar) would be dropped in and put onto a board that replaced the KIO3. Guess what The USB to UART converters are identical to that solution. The only difference would be that you don't have the RS232 level signals that have to go through the RS232 chip that is in the KIO3 right now... It doesn't really change much. Granted it puts every one on a level playing field as to what USB chip is used but buying the USB to UART converter from Elecraft does just that as well.

That is so cool about the K3 and its modular design. Again, the whole issues of drivers come up, but I am sure Elecraft would keep up with it all.

By using a standard RS-232 port Elecraft has provided greater flexibility. If they had provided a USB port then everyone is stuck with it. A serial port can be interfaced to USB using a readily available and inexpensive adapter, or, as has been pointed out, by installing a PCI serial card in an expansion slot. A USB device can only be interfaced to a PC that has a USB port and drivers for that particular device. Of course, Icom will ensure that the drivers are available today to connect the thing to Windows. But drivers may not be available for other platforms (as was the case with the RigExpert interface I sold because I could not use it under Linux) and they may not be available at all in 25 years time by any OS which is not an unreasonable time for someone to still be using a radio (even if not the original owner.) Whereas you can be pretty damn sure that RS-232 ports will still be around, and there will be adapters to interface them to whatever type of peripheral connector is popular at that time.

And unless one has a rigorous, structured software testing effort, problems such as those with DSP and NR will come back and bite you every time.

Re: [Elecraft] WTB - Kent single lever paddle
Ralph, I do not have a single lever paddle for sale, but I suffer from similar problems. If you cannot find a decent single lever paddle at a price your ham budget can afford (the Bengali is outside my price range), I suggest that you try one of the K1EL keyers in Ultimatic mode - it works for me - it makes a standard paddle respond almost like a single lever paddle, press the dash and it gives dashes, press the dot and out comes a dit - it just feels right to my brain. I have been asking periodically that the Elecraft built-in keyers support Ultimatic mode for folks like us, but so far, it has been low on the priority list (but is not being ignored). 73, Don W3FPR Ralph Tyrrell wrote: Well I think I do.

I optained an MK-33 Whiterook single lever key and it works well, but has no adjustment and is not heavy enought to stay put without putting my other hand on it to hold it. So any comments from Kent single lever key owners? Does anyone want to sell one? Does anyone in the US sell them?

Re: [Elecraft] K3 Utility RS-232 ComPort4
Since I was messing with computers, and I had everything to hand, I just tried installing the Prolific drivers, from their website, on a W98 machine that I'm configuring, and then the K3 download program. It all worked as advertised, no problem, so it does work, at least sometimes. Just think, if the K3 had nothing but the USB interface how difficult this would be. At least, you could use a real serial port, if necessary. 73, doug From: Dick Dievendorff [EMAIL PROTECTED] Date: Mon, 25 Aug 2008 19:39:19 -0700 Content-language: en-us The K3 Utility gets its inventory of COM ports from the registry.

Re: [Elecraft] Firmware and DSP Upgrades
Bob, I can assure you that each released 'beta' firmware version has received testing by the Firmware Test Team, and we are *not* the programmers. Often times we are looking at a specific function that has been added, but we also try to ring out the normal operation of the radio as well (regression testing). Sometimes we miss, and the residual problems are not discovered until the firmware is released to 'beta' status. When the problems discovered by the users of the 'beta' release are solved, the firmware is released as a 'public' release. Now, consider that those problems identified by those trying out the beta version and being worked at the same time as the new and added functions are being worked by the Firmware Test Team, the result is that there are few 'public' releases at this time. The newest firmware with the latest fixes as well as new function are to be found in the 'beta' releases. Sorry, but it is a situation of limited resources doing the best we can to provide you with the 'latest and the greatest'. In time, the new functions should diminish, and you will see more fixes in the firmware releases. Right now, the concentration seems to be on enhancing the sub-receiver functions. Be patient, the comments from general users are not being ignored, but they may not be mainstream at this time. 73, Don W3FPR BOB PHILBROOK wrote: I don't know to what extent or to what degree the tests of K3 firmware and DSP upgrades must reach before being released for general use. However, it is apparent to me with the numerous issues with NR and DSP that more needs to be done before K3 software products are released for general use. While I have no aversion to software upgrades, one does not want to trade one set of problems for others. This, unfortunately, appears to be happening more and more as the software becomes more extensive in capabilities. I don't know if Elecraft utilizes such techniques, but independent verification and validation (IVV) of software has proven time and time again to work. One cannot expect a software developer to adequately test his work. Independent testing by a third party against approved criteria catches many bugs and problems developers fail to see. And unless one has a rigorous, structured software testing effort, problems such as those with DSP and NR will come back and bite you every time. Having software tested by the developer often leads to the old problem of two steps forward and one in reverse with software releases. I make the suggestion that more time be spent proofing firmware and DSP upgrades and for Elecraft to employ software IVV.

Re: [Elecraft] WTB - Kent single lever paddle
Hi Ralph, So any comments from Kent single lever key owners? Does anyone want to sell one? Does anyone in the US sell them? I bought the Kent Single-Level paddle ($140) from HRO here in Denver a few months ago. Having seen some discussion on this reflector I thought I'd give it a try. I've use Iambic keying with dual-lever paddles since the beginning of my ham career and have found that switching to a single-lever technique is not for me. I'll sell this Kent paddle with an attached shielded cable and 1/8 plug for $125 shipped. If interested let me know.

Re: [Elecraft] WTB - Kent single lever paddle
Take a look at N3ZN's single lever key: http://www.n3znkeys.com/modelznSL.html While the price might be a bit higher than you're looking at, his keys are excellent quality and craftsmanship. I prefer my N3ZN iambic key over the revered Profi sitting beside it in the shack. The Profi has better and more solid feeling space adjustments, but the ZN paddle just feels better in action.
