Re: [Elecraft] OT: Bose QC Mic Modification
I used to work in the audio industry. Was working for a higher end amplifier manufacturer. We always thought that BOSE actually stood for Bring Other Sound Equipment. It was also often said No highs no lows it must be Bose. Honestly though some of their professional line of amps were quite well made and designed but that was because they farmed those out to us 100% we designed and manufactured them for them. A great set of headphones for anyone who wants external noise isolation and wants good quality audio is the Etymotic ER-4P. I have a pair of these and have gone to an audiologist to have custom ear molds taken and had earpieces made by Westone. Westone makes hearing aids and makes for a wonderful addition to the Etymotic headphones. I can wear these headphones all day at work and not have even the slightest bit of fatigue. The ER4P's are probably the most transparent audio reproduction system I've ever heard. I've not spent large periods of time using these headphones during a contest but I can assure you all that they are completely flat and un-coloring when listening to music. I can't see how they'd be anything less than stellar when listening to the airwaves. Furthermore I can assure you that you'll never find any sort of active noise canceling that will do as good of a job at external noise reduction than the stock ear pieces that come with the ER-4P's. I have used them for a while during a field day and there is NO hearing the generators in the distance! This is crucial in gaining maximum dynamic range when it comes to the AF range. Also if you go to the Etymotic website and see the price don't be too put off by that as they can be found MUCH cheaper on the web!

Re: [Elecraft] Fix the old amplifier......leave the K3 alone!
I agree an inhibit pin is a very good idea. One must always remember to connect it of course. The system needs to fail safe. QSK is not used above HF as much and a radio that automatically allows a delay is far safer than one that produces power immediately unless an inhibit line is used. If that inhibit line was an enable line, I think it would be far safer still. For those who naively carp one should simply speed up ones amplifier - be aware that there are several things that must happen in the correct sequence. The RF relays must switch and settle, then the PA bias must switch, e.g. 350V to the screens for a tetrode. All this before the RF arrives. At HF this is easy, just use a pin diode or a vacuum relay for RF and a triode. At VHF is is much harder. PIN diodes are too detrimental to the noise figure for RF and the 350V screen supply tends to need a relay because of the shunt regulation. Good chunky high power coaxial RF relays available for sensible prices tend to be slow, even with a speed up circuit. They may switch in a few mS but the contacts may bounce for considerably longer. The TX might not mind but the isolation will be poor and the pre-amplifier will suffer. When you are switching a kW VHF amplifier all this really matters and asking for it to be done in less than 10mS is a challenge. Most of it is the RF relays and although small SMA relays do switch RF very quickly, they are only good for a few 100W. There are many K3 features that are totally useless for me. I don't suggest removing top band or AM to save money because I don't need it, so please don't suggest useful firmware features are unnecessary just because you don't need them. -- View this message in context: http://www.nabble.com/K3-and-linear-amp-tp16180386p16219261.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I'd be careful there... I've not built a KX1 yet (but plan to) anyway I just figured I'd take a look at the schematics to see if there was any way to help you out and keep you going on your build. Anyway the NE602 that is on the board specs 8.0V as its MAX Vin. Seems to me like you have a problem with your 6V regulator. If you had a bench supply you could remove the regulator and then hook a bench supply in there once setting it to 6V and could continue on the build.

RE: [Elecraft] K3 and linear amp
If Elecraft could add a menu item that allows the user to select from a list of delay times, including the current value set as a default, then everyone would be happy and not have to make hardware changes to their amps and those with faster amps won't have to do a thing. I for one am not blaming Elecraft for the deficiencies of my amp, but am just asking if they could modify the firmware in the K3 to allow me and others to select from various delay times. So far there's been no response from Elecraft concerning this subject after a few days of discussion on this list. We don't even know if they could easily make the modification in the firmware.

Re: [Elecraft] K3 Configuration
Hallo Ian, In the manual, once you have finished the calibrations, it says to turn off TECH MD. You don't really have to turn off the TECH MODE. The manual, imho, tells you to (suggests that you) turn off the TECH MODE, so that the chance of changing a sensitive menu item by mistake is reduced. I sometimes have it on and sometimes have it off. The SSB power level problems discussed recently on the reflector don't appear to be caused by the calibration at 1mW, 5w and 50W.

I've got a K3 on order, and I'm not worried at all about timing issues switching my amplifier. I use a microHam CW keyer to key all my rigs.

Re: [Elecraft] K3 and linear amp
Hallo Roger, delay times. So far there's been no response from Elecraft concerning this subject after a few days of discussion on this list. We don't even know if they could easily make the modification in the firmware. Elecraft has said in the past, several times, that they will be adding this to the menus sometime in the future. Also The FAQ on the Elecraft web site has the following information (for at least 6 or 7 Months now): === Is there a relay output from the K3 to switch on an external amplifier? If so, is it done via the accessory connector on the rear panel? Yes; it has its own connector (KEY OUT) on the rear panel. The KEY OUT line is a MOSFET, open-drain (equivalent to open collector in a BJT device). It can handle a lot of current AND a lot of voltage. Exact specs TBD. Does the K3 have a variable delay (0-50ms) to control older amp TX relays (i.e., SB-220, L4B, etc.)? Yes. It also has a separate PTT input jack, so you can pre-switch the amp using a footswitch, etc. This delay is provided to prevent hot-switching of amplifiers and the adjustment range will cover any likely need. The variable delay is a feature that will be available after initial shipment. What is the voltage and current limit to control TX amp relays? The keying device is rated at 200 volts, 6 amps. === http://www.elecraft.com/K3/K3FAQ.htm vy 73 de toby ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] WB3AAL out on the AT 22 March
Hello, Today NK8Q, Mark and I will be hiking about 1/2 hour on the Appalachian Trail somewhere north of Allentown, PA. We should both be on the air around 19:00 UTC and will be there until 23:59 UTC. There is a RTTY contest going on today so if the usual QRP frequencies are filled with RTTY, look for us a little lower in the band. Look for Mark de NK8Q on 40, 30 and 20 meters with his Elecraft KX1 and possibly his Rockmite 40. Look for Ron de WB3AAL on 80, 40, 30, 20, 15 and maybe 12m with my Elecraft K2. If 20 meters is busy around the QRP freq. with RTTY, look for me around 14.030 or lower. I have 926 QSO from the AT now with 48 States under my key. Still looking for HI and MT. I also have 24 countries under the key and last time out I worked into Europe with no problems. If you work either Mark or I, please spot us on the DX Cluster and or the e-mail list. This is the last outing for the 2007/2008 season of the Polar Bear Moonlight Madness. Hope to see a moon tonight. Weather now in around freezing with snow coming down. Up in the area we will be hiking the snow is a littler heavier. The system is to be clearing out later in the afternoon. So look for mark de NK8Q PB #4 or Ron de WB3AAL PB #1 from the Appalachian trail later today. 72 and Thanks, Ron Polityka WB3AAL FISTS #10393 www.wb3aal.com www.n3epa.org/ K1 - SN 01011 K2 - SN 01392 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 and linear amp
I think the problem is not elecraft rigs but amplifiers that have unreasonably slow switching times. 10msec or longer is unreasonably slow and I think it's 'unreasonable' to blame the manufacturer of the radio because the amp manufacturer saved a few bucks and used a cheap, slow relay instead of a proper RF relay. You can't blame home-brewers of amplifiers who has to search for reasonable priced HIGH power relays. That's a group of people who were respected by Elecraft builders, isn't it? 73's, Evert PA2KW -- Don't complain. Nobody will understand. Or care.

[Elecraft] Reverting Firmware on Wiki
Also available from the main firmware page at: http://www.zerobeat.net/mediawiki/index.php/K3_Firmware and credited to David. There may be some reason at some point in the future where a previous load of the firmware is desirable, but I do think it should be noted that the coders at Elecraft mightfind this to be against their best intent and efforts. Some other brands have had - shall we say - an impossible time of always making the last update the best update, in fact major problems have been added to fully functional firmware after revisions and even complete rewrites. Can you imagine going back to version 1.x because it works better than version 2.x? The idea with K3, which I'll accept until I experience otherwise, is that the last release (most current) will be the user's choice and should be loaded reasonably quickly after it's available. To me, this lofty goal is achievable with K3, and less likely with most of the other brands because they have software by committee, where as Wayne and Lyle can keep control at Elecraft. As a programmer I can say - still not EASY - but manageable. ;-) --- [Elecraft] Reverting Firmware David Ferrington, M0XDF M0XDF at Alphadene.co.uk Sat Mar 22 10:36:37 EST 2008 Sorry if you get this twice - resetSince a few people have asked me how I do this, I've put a page on the Wiki http://www.zerobeat.net/mediawiki/index.php/Firmware_Revertingexplaining how.Please note this is not an official solution by Elecraft, but it's simple and works.I'm not aware of an official reversion process from Elecraft.If anyone has a simpler method etc. please let me know.-- 73 de M0XDF / K3 #174 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Hello Well, after re-soldering what I thought was every connection on my K2 about 5 times because the receiver wasn't working, On the sixth time I found an un-soldered pin.

[Elecraft] K2 BFO Test problems ( Align. and test, Part II )
Hi all, In the process to test and alignement Part II, I have the following issue: I don´t get the correct range of BFO values. In my case the set of values are: - Using CAL FCTR ... 4913,63 Khz. - BFO High Freq. .. 0,00 - BFO Low Freq 4912,60 Khz. When I try to set up all filters following the instruccions on page 93, I have got the correct values in CW Norm. and LSB modes, but I can´t get the correct values in CW Rev. / USB modes. The maximun value that I can get in this modes is 4914,00 Khz. The rest of tests included in this section are corrects Note: In my K2 kit I don´t received ( or I have lost it ) the diode D36 - SMT1B and I have replaced it (temporarily) for an IN4007. Could be this change the reason of my troubles ???. Of course, I checked and re-checked the values and solders of all the components involved in the BFO schematics ( L33, D37, D38, C169, C173, C174, X3 and X4 ) All suggestions will be appreciated. 73´s Toni, ea3gby ( K2 - s/n 6379 in building process ) Looking for last minute shopping deals?

Re: [Elecraft] CW Decode
Frank, Ham Radio Delux has a code reader in its Beta Version in its Digital Master 780 digital sub program. It will copy hand sent Morse to a certain extent, but I can not find a signal on 20 meters this afternoon that it can copy as well as I can by ear. The program does a good job with PSK-31 and RTTY, so I speculate that writing code to decipher hand sent Morse is very difficult. It can probably do a good job with machine sent Morse, but it seems to be very critical of spacing, much more than I am copying by ear. It may be that I am influenced more by content and knowing what is coming next. The bottom line is that I don't think the HRD program at its current development level would be an aid to learning Morse. I don't know a better program to suggest. There are some commercial Morse readers on the market, but I have not tried them. Simon Brown, the author of HRD frequents this reflector, so perhaps he will give us a rebuttal. It may be that I don't have his program set up properly. I am a very new user and that is a strong possibility. For learning Morse I think the old fashioned way is the best way. Start with a hand key and copying by ear. Start slow and work up to a better speed. I have been taken to task by some of the digital generation for that advice, but novices grinding out the code with each other worked for a long while until the FCC in all its wisdom decided to do things differently. I wish you well in getting into Morse. Cookie, K5EWJ --- Frank MacDonell [EMAIL PROTECTED] wrote: Can anyone recommend software for CW decode.

Re: [Elecraft] K3: concern about flexing FP board
I noticed this, too, until I continued with the assembly. It seems like there was a little rubber-like bumper on the PC board near the MV button which pressed up against the 2D fastener (as I recall) at the top right of the radio when the front panel is fitted to the rest of the radio. This provided enough support for the board to keep the buttons from moving on my radio.

Re: [Elecraft] K3 2.7kHz filter DSP FC
Hi Guys, I know I am a couple days late on this, but I have been wanting to comment on this audio thing. Billions of folks may be content with restricted audio, but I wouldn't be. Let me first state I do a ton of listening or monitoring on all modes. Right now I am on 7.020 using a wide filter set for 3.6 KHz listening to CW stations coming and going as I work in the shack. A also have a few AM programs on the weekend I like to listen to. With my outboard audio amp and bookshelf speaker system it reminds me of the old days when REAL communication receivers had room filling volume. Let me move away from phone operation and talk digital, I do a little of that as well. Using programs such as HRD's DM780 and MixW if you have a receiver rolling off the low or high end response you will loose the ability to monitor more effectively on modes such as PSK31. Now for you guys that can only think narrow as well as listen that way, let me explain what I do in my shack. When I am monitoring the bands on PSK31, I use the widest filter possible. At the extremes of the rig's bandpass their maybe a problem on transmitting a very low or high tone. However both programs mentioned above have a centering function that grabs the signal and puts it at 1500 hz. If you are using CAT with your rig, this is all automatic, it centers the signal right on 1500 Hz and adjust the VFO accordingly. Say I find a brand new country and find him at 100 Hz using DM780, I hit Center and it moves the station of interests to 1500 Hz. Then I can point and click for a narrower receive filter. I am now ready to transmit. If you have ever gone fishing, you catch more fish with a large net than you do with a small one. You can always throw back in the small ones or unwanted ones. If your receiver is restricted, you will and can miss stations that might interest you! Operators that use DM780 with SuperBrowser know what I am talking about. Just for fun I decide to see how many stations I would missed with a rolled off response on the low end of 300 hz, typical communication grade receiver of yester year. I fired up non communication grade receiver and set the cursor at 70.1 hz, I still got good print on PSK31! So using a channel width of 30 to 50 hz on PSK31 means I could miss up to 7 to 4 station respectively. This doesn't even count for the higher end response! For those that would like to see, I have jpg's of stations received at 70.1 Hz and 3604.3 Hz that printed cleanly I can send to those that are interested. I have other receivers that could do better on the high end, but that is not the point I am making here. Over the years I have a ton of receivers, to be honest I would not know how to classify a communications grade receiver. When I hear communications grade I think heavy, military like ruggedness, and versatility! I never think 300-300 KHz, but that is just me. So end the end, this cool aide drinker would like a choice of favors, the more versatility, the better for me. I hope in the end the K3 has the ability to go wide on IF/audio frequency response and then let me choose how narrow I need to go on all modes. There a lot of reasons to have a nice flat, wide, low distortion bandpass, not just for good sound, but that would be great also! I would be curious to what the K3 ultimate bandpass would be and would that also be completely adjustable? Yes I did glance at the various pdf.s, but didn't see a spec for this. Thanks for letting me add my 2 cents worth. 73 de w5jay/jay.. Paul Christensen wrote: Bruce, as Barry points out, the K3's audio response really needs the ability to extend down significantly lower than the current ~ 250 Hz we're not concerned with the broadcast of music in our service, then the male voice (lowest relevant fundamental of 70 Hz) and certain digital Billions of people are quite happy with the 300kHz cutoff used by the public telephone system (a total of 3.1kHz between 300 and 3.4kHz). The critical frequency for speech communications is the lowest formant frequency; it is the resonances in the vocal cavity that convey speech, not the fundamental. The lowest formant in normal speech (formant 1 for u) spans about 200 to 400Hz, so 250Hz probably is a reasonable compromise; it will include the peak and only slightly distort the lower edge. modes in SSB mode (e.g., PSK31) may be used to establish the lower response threshold. When you use digital modes with the receiver configured for SSB, you are really using the audio path as a final IF of about 1kHz. As long as the audio passband is flat across the actual digital signal, it doesn't matter what its centre frequency (final final IF frequency) is. That's basically the strategy used by telephone modems (except 56kbs ones, which play tricks with the digitisation of the signal). The faster ones use a carrier of about 1800Hz (nominal channel centre is 1850

[Elecraft] Re: K3: concern about flexing FP board
Doug, If your front panel is in the correct position with respect to the PCB and the chassis, there should be an insignificant amount of adjacent-key movement in the Z axis. I'll have Elecraft support contact you to help with this. 73, Wayne N6KR On Mar 22, 2008, at 4:23 PM, DOUGLAS ZWIEBEL wrote: I'm wondering if I left something out or what.

[Elecraft] K3: using vox as PTT for digital modes
Hi I tried using VOX as the PTT for digital soundcard modes but that doesn't seem to work. That would be a neat feature addition as I do have a second soundcard in the PC dedicated for HAM digital modes, so no windows sound will trip the VOX. I was using a signalink SL1+ before that basically activated PTT when detecting audio out of the PC. So Wayne please add it to the todo list ;-) 73 de K6TE Wim Looking for last minute shopping deals?

Re: [Elecraft] [K3] Disable 5mHz
David Douglass wrote: Quick question, can I turn off the 5mHz band, so when I scroll through the bands using the up and down band buttons, it doesn't show up?? We don't have access to this in Australia, and I don't have any real interest in listening in!! A mapping function which will allow you to disable a band or bands is on Wayne's list. It would not only be useful for those of us who want to ignore 5 mHz, but for contests, for example when you might want to temporarily disable the WARC bands. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3: using vox as PTT for digital modes
I'd rather not see this on the todo list. I feel the PTT on the DB9 is more than ample and will prevent many others from sending many windows sounds over the air. Most software will key a rig over CAT commands and this is the way this should be done.

Re: [Elecraft] K3: using vox as PTT for digital modes
I tried using VOX as the PTT for digital soundcard modes but that doesn't seem to work... A while back I used VOX in DATA A mode. Haven't tried it in a while, but the intent is that it work. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] OT: Bose QC Mic Modification
I second Brett's comments re the use of custom fitted in-ear monitors (IEMs) for great isolation and sonic clarity. Properly fitted, they are very comfortable, provide about 25 dB of external isolation and you hear exactly what your receiver is producing. I do live sound monitor engineering on a weekly basis and have used a variety of low, mid and high-end IEMs ($60-$500+) over the years. The best price/performance I've found so far is the Live Wires IEMs. They are not cheap ($249) but for the money (IMHO) there is nothing better.

[Elecraft] Elecraft CW Net Announcement
Good Evening, Another snowy week has passed. The daffodils are sprouting but the snow makes them slow in growing. There are some crocuses and snow drops showing though. I was surprised by the snow a few mornings back. It awoke me when the sun hit the tree over the house and the snow started falling in large clumps. When I had gone to bed it was raining heavily. Sometime during the night we received four inches of snow. I have listened to 20 meters only a little this week. I had many errands to take care of and projects to finish. Now for a little time on the air. From what I read yesterday we have another year of low sunspot numbers to contend with. But that does not always mean the bands are dead or weak. I tried for a sked into Alabama only to be greeted first by a G0 station and later in the week by a DK station. Seems 20 m was a little long those days :) 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 warm, Kevin.

[Elecraft] KPA100 initial tests
Just a minor problem and looking for some advise. All resistance checks are fine.All voltage checks are fine except Pin 27 on U1 It's showing about .5 volts. Also noted that the LED on the K2 is at the top of the scale. Based on the charts in the back of the KPA100 manual, Pin 27 should go low when the amp is in TX. The LED on the K2 seems to support the fact that hooking the amp up puts the rig in transmit. Naturally, I have some digging to do but was curious if there is anything in particular I should be looking at. Also,I had the power adjusted on the K2 to around 10 watts while doing these tests. Is it possible for the KPA100 to sense the power level of the rig and go into TX. Any thoughts?? Thanks and have a great weekend all 72 Jerry N0JRN ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
