[Elecraft] Firmware Ver 3.30
Hi, I've had my K3 (S/N 3431) up and running about two weeks. It arrived with version 3.30 installed. I'm understanding from reading here on the reflector that version is beta and is not available for download by K3 owners due to some unforeseen difficulty. Two points. So far I've found no major issues other than S-2 noise on 20 meter where it's not present on my IC-756ProIII. On the other hand I'm somewhat concerned about receiving my radio with unreleased software making me a unknowing test subject. Should I revert to an earlier version to avoid learning about my new radio with unreleased software that will obviously change in the near future. Second point, to Elecraft management. It seems unwise business practice to provide a product to customers that has not gone through necessary testing and release and especially without the customers knowledge. If I'm misunderstanding something here please help me understand and I do apologize if I do misunderstand. Have a good day and 73.

Re: [Elecraft] Any solution to the audio blast issue yet ?
A peak limiter combined with a fast short or open circuit is the only way to prevent ear damage. I've listened to earphones protected by vdr and, although the peak voltage delivered to the headset is limited, the waveform simply flattens off and the audio power pulse is still deafening. This problem I think is addressed by telecom users eg in call centres and has been around a lng time. One of these days I'll make a little outboard suppressor to use with my headphones where-ever I take them. David G3UNA If I may chime in here, I hope very strongly that nobody is using deep- in-the-ear type earbuds with the K3 or any other radio.

If you are like most of us, I think you will find that this rig offers loads of possibilities rarely found elsewhere. Regarding the firmware, the last official regular version was 3.14, which is still offered on the Elecraft website. However, the K3, being at heart a software defined radio, has challenged the usership to make requests and offer suggestions to further add to the value of this fine rig. Thus, the engineers at Elecraft, always in turbo mode, have been responding with upgrades and updates almost continuously. Most K3 owners subscribe to this culture of constant improvement. It seems to be exclusive with Elecraft because management and engineering is so continually tuned in to the needs and desires of its customer base as reflected in the reflector. Indeed, you will find that Wayne and Eric chime in quite frequently, as they always seem to have one eye on the list. Before being released as beta, the firmware is field tested by a small, but critical, group of users that thoroughly exercises the coded functions and reports back with their findings. In most cultures, the code would be released as final, but the relationship between Elecraft and the usership is so dynamic that seldom is anything settled. In comparison, consider Microsoft releases, which are final, until the next Tuesday patch releases come down the pike. So, if you would feel more comfortable with a final release on your K3, you can certainly downgrade to release 3.14, or you can benefit from the constant drive towards perfection with 3.30, which you will find just peachy.

Hi Tom The next beta version due to be released soon, does have a similar feature to that found in your old 850.

So the K3 will show correct readings at a level where the typical S-meter will indicate nothing.

[Elecraft] If I Were King of the World - or - Elecraft Dreaming
Good Afternoon All To toss some more fuel on the fires of ideas for Elecraft gear, a few of my thoughts. The target of our (KB4WYR and myself) current radio buildup project is an upper mid level VHF/UHF/microwave weak signal station. That target is well down the road with probably hundreds of steps between the start and good enough. To that end we decided that we'd build as much as we could. Additionally, we decided that a K3 was going to be one of the foundation stones of that station. The other stone at the very foundation was/is a K2. As these two rigs can use the same set of transverters the K2 seemed like the best starting point. To that end we have built up a K2/qrp with all the bells and whistles (ok I still need to trouble shoot the ATU). The tower and six meter transverter look like the next steps. (That tower is going to be the hard part $$ wise.) So with that in mind, things I'd like to see Elecraft do: 1. High end preamps for all the VHF+ bands they have transverters for. 2. More transverters! Just keep right on going up the ladder of bands. (you can stop when you get beyond light!!!) 3. Amps, esp high power amps to go with the preamps, sequencers and transverters. Now this is an area where the market is NOT saturated! 4. And having nothing to do with VHF+, an MF receive antenna/preamp intended for indoor use. Perhaps take a highend AM broadcast receive antenna system and adapt it to 160 and maybe 80. 5. As long as we're at the bottom end of the spectrum, high end receive converter, antenna preamp system for the sub-550khz bands. 6. More test equipment to go with the wide range of gear available. And with enclosures available for all of it. I think that's enough to keep the folks at Elecraft off the streets and out of trouble for at least one long weekend! It's probably a good thing I'm not King of the World, but it's fun to dream.

I was in a CW QSO on 20 meters at the moment the audio blast occurred. I probably had bandwidth set to 400 Hz, using my 400 Hz filter, and may very well have had the NR on, probably at setting F1-1.

Although the blast startled me, I did have the wits to continue sending my report, before pulling off my headphones and switching the rig off and on in order to stop the sound.

Re: [Elecraft] [K3] Serial port RTS problem [was: Different mode]
It may be a too obvious comment, but the easiest way to tell what is going on is with a serial breakout box. If you get one with LEDs you can visually watch the status of the control and data lines in real time.

Re: [Elecraft] K3 - Channel hopping across bands
Dave G4AON wrote: The next beta version due to be released soon, does have a similar feature to that found in your old 850. Unfortunately the K3 doesn't have a V/M button like most radios (such as yours and my TS-480SAT), so it will still require the memory contents saving to VFO before you can transmit. Wayne told me that the channel hopping memories will soon load all the attributes so you will be able to transmit from them without an extra step. The regular memories already (in the latest beta) support live reception and will switch bands as appropriate. However I would have thought the clicking of relays as the radio switches from band to band would discourage anyone from actually scanning a set of memories in different bands. - Julian, G4ILO.

Re: [Elecraft] Serial port RTS problem [was: Different mode]
Hi Don, i had just come to the same suspicion when I read your email. And we are right. My homebrew desktop system (Tyan Tiger dual AMD board) works fine. This is a Dell problem. I will look around to see if there is an updated serial port driver that fixes this. I will be pleasantly surprised if there is. In all likelihood, I will simply have to eschew using these control lines on this machine. Bill W5WVO Don Wilhelm wrote: Bill, Just out of curiosity, I tried it here too.

[Elecraft] Elecraft CW Net Announcement
Good Evening, This week was rather pleasant. I got a lot of work done inside and out and then, on Thursday evening got caught in a long novel. I was able to put it down the first night but last night (or should I say this morning?) I read until 3 AM! And then again today until I finished it. Wow! I normally don't read much fiction but was so enchanted that I was living inside the story. It has been far too long since I have had this pleasure. I used to read a lot of fiction but in recent years (the last ten or so) I have been deluged in a mountain of textbooks, trade magazines, and journal papers. Reading for fun is only a small part of my life left to my monthly Analog subscription. I have been reading it since around 1963. However, now that I have completed my novel I must go back to living in the real world again. Propagation on twenty and thirty meters was good this week. Even before the new sunspots appeared the conditions were good. I do believe it is due to the sun angle and the change in season. The sun is rising later each morning and setting much earlier each evening. This has caused the ionosphere to be different than it was only a month ago when conditions were not as good. Hopefully we can plot a trend line but I know that is never a predictive certainty given how odd propagation and solar conditions can be. The best measure of success is a simple CQ. Listening is not a good way to determine if the band is dead. If no one calls none of us can hear them. A Zen coan if ever there was one :) Please join us tomorrow evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP relay help) Sunday 2300z (Sunday 4 PM PDT) 14050 kHz Monday 0100z (Sunday 6 PM PDT) 7045 kHz Stay well, Kevin.

[Elecraft] [K2] RE: KAT100 error
Don I posted these two post on the reflector via the web site and they are still showing as pending so I am trying to do it through email. If two post show up . my apologies. Good morning Don and thanks for the reply. I ran the test on the K2 into a dummy load. It tunes great on all bands and the only time I see the HiCUR message is if I max the power out setting. Actually I think it starts at around 13.8 and above. So, I pulled the Firmware to re-seat it and low and behold the number 1 slot doesn't look quite right. I do get continuity from the socket's solder pad to the pin on the firmware, but perhaps it is not enough? I will order a new socket today and once that is installed I will go from there. If this socket is in fact bad, could it have caused the firmware to go bad as well ... should I also replace it? I only ask because of the time involved for any orders to reach me from Elecraft. Thanks for your help Don, I will post my results once I have replaced the socket. POST 2 UPDATE:KAT100 Issue Removed the 20 pin socket for the firmware and replaced with a new one. Same problem. I also received an email from WB4DAD suggesting I try replacing the diodes at D1 and D2. He said he had a problem with his KAT100 that sounded a lot like mine and that fixed it for him. I have an email in with Elecraft support to get their thoughts on this. In the meantime I ordered the diodes today so I will have them just in case.

When I set the antenna to 2 and turn off the K2 and then back on I noted the antenna back on ANT 1 I also noticed when first powered up the lights on the KAT100 are bright but then dim a bit.

(Using a dummy load as well as an antenna) I checked the solder connections in the KAT100 and retouched a few. I noticed no change in behavior. I put the radio away for a few days and revisited the problem today Before doing anything I did a SWR Bridge alignment on the KPA100 just to be sure nothing had changed. I adjusted for 0 voltage using a DMM as instructed in the manual. Currently, the tune sequence gives a 1.0-1 reading on the K2 meter but the scale lights on the KAT100 do not light up while tuning or when keying. The antenna and power lights are working properly. When keying 100 watts into a dummy load the power is reduced by various amounts depending on the band and the K2 shows HI Refl, the same symptoms using an antenna.

Re: [Elecraft] An interested link
A good link for learning how to generate splatter. ESSB has no place on the HF bands. Just about everyone of these ESSB stations cause a lot of interference on adjacent frequencies. This curse called ESSB has spread around the world. Just about every second JA SSB station that I hear has such excessive amount of bass frequencies. Its bad enough having to deal with accents without someone sounding like a monkey in a drain pipe. The YB stations are the worst. Ask anyone about the splatter on the 40 meter band caused by YB stations running ESSB equipment flat out. They are causing havoc on the CW end of the band with buckshot. This ESSB practice has become the ham version of CB amplified microphone practice, all knobs to the right! It was such a pleasure tuning across the 20 meter band with the Scandinavian contest running. All the Scandinavian stations were all using excellent communications quality well processed audio, it was a pure delight to my ears. Even stations that were S1 could be understood. I must also congratulate all the Scandinavians for operating their equipment with such professionalism. There was hardly any splatter from most of the big guns. 40 db over S9 signals and all were clean, amazing. I was using a club station K3. The Narrow SSB filters combined with DSP filtering are superb in contest conditions. I even had 1 or 2 stations pegging the K3's S-meter. I just adjusted the narrow bandwidth and they were gone like magic. The good think about contests these days is that you dont hear any ESSB bassy audio stations around.

[Elecraft] Re： An interested link
I would like to add that we, VR2, are also suffering from CB type splatter generated from YB stations. Their audio is just so easy to be recognised. Again, it has been what I experienced on air and without any intention to bad month any individual YB station. 73 Johnny VR2XMC 寄件人﹕ juergen piezo plebia...@yahoo.com 收件人 Elecraft@mailman.qth.net 傳送日期﹕ 2009/9月/27 (星期日) 11:22:11 AM 主題： Re: [Elecraft] An interested link A good link for learning how to generate splatter. ESSB has no place on the HF bands. Just about everyone of these ESSB stations cause a lot of interference on adjacent frequencies. This curse called ESSB has spread around the world. Just about every second JA SSB station that I hear has such excessive amount of bass frequencies. Its bad enough having to deal with accents without someone sounding like a monkey in a drain pipe. The YB stations are the worst. Ask anyone about the splatter on the 40 meter band caused by YB stations running ESSB equipment flat out. They are causing havoc on the CW end of the band with buckshot. This ESSB practice has become the ham version of CB amplified microphone practice, all knobs to the right! It was such a pleasure tuning across the 20 meter band with the Scandinavian contest running. All the Scandinavian stations were all using excellent communications quality well processed audio, it was a pure delight to my ears. Even stations that were S1 could be understood. I must also congratulate all the Scandinavians for operating their equipment with such professionalism. There was hardly any splatter from most of the big guns. 40 db over S9 signals and all were clean, amazing. I was using a club station K3. The Narrow SSB filters combined with DSP filtering are superb in contest conditions. I even had 1 or 2 stations pegging the K3's S-meter. I just adjusted the narrow bandwidth and they were gone like magic. The good think about contests these days is that you dont hear any ESSB bassy audio stations around.

Re: [Elecraft] An interested link
The History section of that web site applauds the fact that ESSB enthusiasts have been able to push their 3 KHz bandwidth rigs to 4 KHz and beyond using external equalization, and it points out that the leading edge for EESB is now moving past 6 KHz in transmitted bandwidth thanks to some of the new SDR rigs. Here are a couple of illuminating and disturbing quotes: It's becoming more recognized that the improved fidelity of ESSB has signal-to-noise advantages over the old traditional forms of narrower SSB ... with the decline of new amateur radio operators to populate the bands, the wider bandwidth necessary for high quality SSB is not as much of an issue as it was 10 or 20 years ago. One of the hams lauded in that section for his work with ESSB lived near me when I was still in Scottsdale, and you could hear his splatter as much as plus/minus 8 KHz when he was on the air with his buddies on 20m in the evening. He was a casual friend of mine so I mentioned it to him, and his dismissive answer was that he must be overdriving my rig ... even though I told him that I had checked for that by using a piece of wire for an antenna to keep his signal below S7. I often monitored those guys while I was doing work-related stuff on the computer. They constantly tweaked their equalizers and critiqued the sound of each other's modulation, but I never once heard any of them check to see how wide they were. I have no problem at all with people experimenting with ESSB as long as they avoid interference with other activity on the band, but promoting ESSB as a mainstream mode on the HF bands seems to me to be the same as advocating an across-the-board return to AM, complete with its power inefficiencies and waste of spectrum. I just don't get it. It's just another reason for me to stick with CW, I guess ...
