Re: [Elecraft] K3 microKeyer 2 setup
Hi Part 2 I'm very nearly there thanks to the help given so far. (i) I managed to get through the 6 - Setting Audio Levels to point 8 on page 46. The next step, adjusting the Balance, has no effect on my ALC levels. Am I right to assume that I can ignore this for the the K3? I've done nothing about the DVK tab as I don't plan on using it just now. (ii) I use Winwarbler in DXLabs for PSK and RTTY. I've set this up for FSK. Should I be using the PSK D and FSK D settings on the K3? (iii) When I run a macro (in Winwarbler) on FSK it puts the K3 into transmit, sends the message and puts the K3 back into receive. However, when on PSK the same macro is sent okay but at the end of the macro the microKeyer 2 clicks but the K3 stays in transmit. What am I doing wrong?

Great, Thanks for the info! On Fri, 2010-09-03 at 22:12 -0400, Don Wilhelm wrote: David, Enjoy the build. Yes, the manual is quite good - my 14 year old grandson was able to complete a K2 build using only the instructions and a (very) few helps from grandpa. Enjoy the build, and you can be rightfully proud of the results. I can offer one assist - the varactor characteristics have changed from the time the manual was written, so the variable filter settings for the SSB filters indicated in the manual are no longer valid - the more narrow CW settings are OK. For instance, a filter width as indicated by the K2 display of 2.00 kHz may actually be 3 kHz or more. The best solution to this problem is to use Spectrogram (or similar) to measure the actual passband width. Refer to my website (www.w3fpr.com) article dealing with K2 Dial Calibration for information about how the set up and use Spectrogram to set the K2 filters. 73, Don W3FPR On 9/3/2010 9:45 PM, david m wrote: Control board finished, started on front panel.

Re: [Elecraft] K3 microKeyer 2 setup
Bill, Your point (i) refers to the microKeyer II manual; I can't help you there. Re (ii), you cannot use PSK D with WinWarbler or most other software. For PSK31 and most other sound card digital modes, you should use DATA A. For RTTY, you can use either FSK D or AFSK A; both work equally well. Re (iii), how are you doing PTT? There have been numerous reports of K3s getting hung up in transmit at the end of messages, coming from people who had configured their software to use both software PTT and hardware PTT in parallel. To avoid this problem, you should not use software PTT unless there is no hardware method available. There are several ways of triggering hardware PTT from WinWarbler/Commander via the mK II, so software PTT is unnecessary with this combination. You can turn software PTT off in Commander by checking the Suppress CAT box under the General tab in Commander's Configuration window. There is more guidance on configuring WinWarbler and Commander for digital modes on the K3 at http://www.dxlabsuite.com/dxlabwiki/K3PSKRTTY . I hope this helps. 73, Rich VE3KI GM0VIT wrote: Hi Part 2 I'm very nearly there thanks to the help given so far. (i) I managed to get through the 6 - Setting Audio Levels to point 8 on page 46.

Re: [Elecraft] K2 Assembly
Hi Ross- The SA612 is identified as an alternate for the SA602 in the manual (see Page 3 of Appendix A, Control Board). I believe there are eleven I.C.s in 8-pin DIP packages. They are all listed in the parts list. Perhaps you can identify that blank one by a process of elimination if it's the only one unmarked. You are likely right about (b). Suggest a note to support at elecraft dot com about the issue. They should be aware of any un-marked parts going out by mistake anyway.

[Elecraft] P3 Understanding the REF LVL Settings and Signal Level in General
I am trying to get a better understanding of the P3 signal level scale (left vertical scale) with respect to absolute signal levels and the S meter readings. I have my REF LVL set to -132 dBm. My first question is: what is a reasonable setting? I merely am guessing at the value of -132 dBm and also I am not quite sure how accurate this is. According to the P3 manual, this is essentially the signal strength at the antenna terminal of my K3 (taking into account the pre amplifier which I happen to have Off). Also, I was monitoring a signal using the PEAK reading capability of the P3 and noticed that this particular SSB signal on 17 meter band this morning read peak about -100 dBm or about a 32 dBm strength over the minimum reading on the scale. I would like to equate this to a rough idea of an S meter reading. By my calculations, this should be a little bit above an S4 reading. Can someone confirm that I am in the right ball park?

[Elecraft] OT - How to contact Vibroplex with a question
A local newbie bought a Vibroplex Vibrokeyer at a recent hamfest. He brought it to me to help him get it adjusted. After adjusting the spring tension (too tight no matter how 'loose' the adjustments made it), and the contact spacing, I noticed that it didn't key the keyer to which it was attached... and when it DID (infrequently) cause the keyer to emit a tone, the electrical contact of either level was not consistent. Using an ohmmeter I confirmed that the GND lead of the connecting cable was in deed electrically connected to the base of the keyer AND the the yoke holding the dual levers. But NEITHER lever gave continuity to ground...! Removing the keying levers revealed that this was in fact, one of the few paddles which came with synthetic ruby bearings which had not long ago been crushed by excessive tightening of the adjusting screws. However, given that the ruby bearings were still in place, they provided for the levers to be well above ground potential to the base, and thus to the keyer itself. The ONLY method I was able to find that each keying lever might have been 'electrically connected to the keyer base was via the (contact-return 'tension' spring in each lever. I've tried to find a contact method for Vibroplex but have had no luck finding ANYTHING, unless I want to place an order for parts or service. Does anyone happen to have a phone or e-mail address for Vibroplex? And more importantly, can anyone confirm that the ONLY source of grounding between the Vibrokeyer levers and the base of the paddle is via the contact return springs? If so, man, that's a HORRIBLY POOR connection to be relying upon.

Re: [Elecraft] P3 Understanding the REF LVL Settings and Signal Level in General
My first question is: what is a reasonable setting? It's kind of a season to taste -- whatever gives a pleasing display to your eyes. When the waterfall is turned on, I find that it's best to adjust the REF LVL so that the noise level is right at the bottom of the spectrum screen. That seems to make weak signals easiest to spot on the waterfall. I am not quite sure how accurate this is. I would guess that typically it should be within a few dB. Let's say within one S-unit (6 dB). I plan to add a feature so you can calibrate it against an accurate signal source. ...and noticed that this particular SSB signal on 17 meter band this morning read peak about -100 dBm or about a 32 dBm strength over the minimum reading on the scale. I would like to equate this to a rough idea of an S meter reading. By my calculations, this should be a little bit above an S4 reading. Can someone confirm that I am in the right ball park? What I do is to remember that S9 is -73 dBm (an easy number for a ham to remember) and there's 6 dB per S-unit. So -100 dBm is (100-73)/6 = 4.5 S-units below S9. So between S4 and S5. Another item on my to-do list is a MENU option to change the scale from dBm to S-units and dB over S9. It's not all that hard to do, I just need to clear some higher-priority tasks off the list first.

Re: [Elecraft] P3 Understanding the REF LVL Settings and Signal Level in General
I just looked it up. The XG2 has a specified level accuracy of 2 dB, and 1 dB typical. A professional lab-quality RF signal generator would typically be about twice that good (hard spec in the 1 dB range): http://www.home.agilent.com/agilent/redirector.jspx?action=refcname=AGILENT_EDITORIALckey=843957lc=engcc=USnfr=-536906709.536910813.00 So if you have access to a calibrated lab-quality signal generator, then use it. But the XG2 isn't bad and is about 100 times cheaper. :=) Alan N1AL On Sat, 2010-09-04 at 11:55 -0700, Phil Hystad wrote: Alan, Thanks for the excellent answers.

I would like to equate this to a rough idea of an S meter reading. By my calculations, this should be a little bit above an S4 reading. Can someone confirm that I am in the right ball park? What I do is to remember that S9 is -73 dBm (an easy number for a ham to remember) and there's 6 dB per S-unit. So -100 dBm is (100-73)/6 = 4.5 S-units below S9. So between S4 and S5. Another item on my to-do list is a MENU option to change the scale from dBm to S-units and dB over S9. It's not all that hard to do, I just need to clear some higher-priority tasks off the list first.

Re: [Elecraft] K3 microKeyer 2 setup
Rich Thanks for pointing me in the right direction. I am so close to a solution but can't cross the finish line just yet. I followed your instructions and managed to get it working for PSK. I even had a qso. Now I've got the RTTY working but for some reason the PSK is playing up again. I get the K3 switching on but there doesn't seem to be any power getting out and the transmit has stopped switching off again.

[Elecraft] Odd behaviour
Hi, Firstly, I'm not generally an SSB operator (in fact I've not done a whole lot of operating since May, but thats another story), but today I took K3 #2184 out for SSB Field Day, MCU v2.05 FPF v1.10 DSP1 v2.6 DSP2 v2.6 DVR v1.03 Anyway, Issue 1. I was using the DVR, and when I selected just 1 play of a memory, and 'late' in that playback, decided to press and hold the same button. At the end of the first playback, the K3 took a long time to switch back to rx (even though it had finished transmitting). Issue 2. While in the 4-5 second gap between DVR transmissions, I was using the sub receiver to tune for multipliers, I would have liked to have been able to see the sub receiver frequency now and again (possibly when the K3 was tx'ing). I would be interested to hear what anyone else thinks of this. Now, hands up, it's the first time I've really used it for SSB, so both of these could be operator error. Oh, and I did have a lot of fun!

[Elecraft] P3 Com Port Issues
My P3 (#318) was delivered last week. This morning I finally got time to assemble it. What a joy! I installed the P3 with the computer serial cable routed through it to the K3.

Upon connecting the P3 today I get Com Port errors (port already in use) when trying to use the logging software. I made no changes to the logging settings, simply routed the serial cable thorough the P3 as designed. Using today's version of K3 firmware. I seem to recall a thread on this subject some time back but can't find it when I need it. Can anyone point me toward the resolution?

[Elecraft] {KX1} DX question
Does anyone know the basis of the distance reported under Details in QRZ.com entries? I recently worked HB9FBG on 500 milliwatts with 6 regular AA Eveready batteries (at least that's what my inline wattmeter said) on a 40 meter dipole up in my attic. The distance from me to HB9FBG was reported as 3947.8 miles. Does anyone know if this represents GPS miles, a straight line approximation, miles reported from some table derivation, miles that represent some approximation of a radio signal's trip up to the ionosphere and back down...? I'm no math genius when it comes to trig but it seems that there could be quite a mileage distance. Also, the .8 in QRZ.com's mileage suggests some technology is at work!

Re: [Elecraft] Z10000 installatoin in K2
The reason for an SMA is that it mounts in a 0.25 inch (6.35mm) hole and can be fitted onto a K2 rear panel with all possible options installed. It was not possible to get a BNC to work under all conditions of K2 options. The particular SMA provides shielding integrity, unlike using a panel mount BNC with a solder lug and center conductor loop.

Thanks guys: I appreciate very much your response. I have every option available in my K2 Jack and I really didn't want to drill another hole in the back panel. I understand the need to keep any stray signals out of this circuit and figured that's why you elected to use the SMA. I just wonedered if I was overlooking something by electing to use the RX ant BNC. I have no room at my QTH for a receive only antenna so using that connectors satisfies my need and makes for a very clean installation. SO, back to the bench so I can finish this little project.

[Elecraft] K2 IC identification
Hi Ross, I had a similar moment of worry when I looked at some of the ICs under an illuminated magnifying glass and just saw a blank top with, apparently, no ID markings. Then by accident, I slightly tipped the top face of the IC away from the light so the top was illuminated tangentially and voila - out popped the lettering in a faint silver glow. In my case, it seemed the silver lettering was very difficult to see if illuminated directly with a bright light source. Try gently re-orienting the IC under the light and see if you can make out the letters any better. 73, John VK7JB This email was sent from Netspace Webmail: http://www.netspace.net.au __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] K2 assembly
John, WOW, only 2 away from the 7000 mark! If you are looking at the really old K2 postings, there are many that have been made null and void by the updated boards. Remember that you have the updated boards in your kit, and you should not have to do any cuts or adds when you add the options. I have 'repaired' several new K2s where the builder tried to add the cuts and wire adds to the K2 control board when installing either the KIO2 or the KPA100. If those builders had read the instructions correctly, it would have been apparent that those changes were only to be done for K2s with serial numbers below 3000. In other words, read and understand, and if you have questions about the understanding part, ask here on the reflector. Enjoy the build, and when finished, enjoy the K2. Additional note (not on my webpage yet) -- when setting the filters on recent K2s, you will find that the wide (SSB) filters are actually much wider than the width indicated by the K2 display - and as a result, the suggested settings for the SSB filters listed in the manual will not work well. The cure is to use Spectrogram (or a similar tool) to measure the actual bandwidth. Refer to my webpage article on K2 Dial Calibration for more information. 73, Don W3FPR On 9/4/2010 10:11 PM, zen...@netspace.net.au wrote: Hello All, seems there's a burst of K2 assembling going on in the world.

[Elecraft] Elecraft CW Net Announcement
Good Evening, Another chilly week. This has been the shortest and coldest summer since I have lived in Oregon. Folks here are talking about summer coats and gloves. They are not kidding! I have only had a couple t-shirt days and those are spaced out on those rare days when the temperature got over 70 degrees. However, there is a silver lining to that grey cloud: the fire danger has been very low. Just means we have to wait for next year to feel warm. Summer started late, is finishing early and was interspersed with many cold snaps so we had maybe three weeks of warm weather total. Even the leaves are changing and the critters are making plans for winter. I have not been on the air much this week but when I was on 80 meters copy was very good. Unfortunately all of that was local. No great shakes for DX contacts but it was fun to call CQ and see who was out there. Casual chats which were tailended by other curiosity seekers was a nice way to spend a few hours on the radio. No points to worry about, no pile ups to fight, just work a few people and find out what they are thinking. Once I make contact I rarely talk about radio since it is obvious that I have one. It is more fun to talk about the garden or the outdoors or just whatever comes up. No pressure to perform just a simple chat. And, since they are locals, we can talk about how cold it is without someone thinking we are a bit whacko :) Please join us tomorrow afternoon and 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 2200z (Sunday 3 PM PDT) 14050 kHz Monday z (Sunday 5 PM PDT) 7045 kHz Stay well, Kevin.

Re: [Elecraft] K2 IC identification
John. Well, I suspect the situation will get even worse with a bit of time. The first thing I noticed was that the resistor color coding did not have the color saturation that was used several years ago, and then the printing on the ICs became more elusive. If you can think like an automated insertion machine, you will have no problem, just expect that 100+ parts that are NE612 will be loaded into your hopper by someone who only reads the label on the shipment from DigiKey, etc. In that case, there is no need to read the actual device markings. Manufacturers are responding to the needs of the board assembly houses which do not need people readable markings. We hams will just have to be tolerant and creative in ways to order and identify the parts that we order. 73, Don W3FPR On 9/4/2010 10:26 PM, zen...@netspace.net.au wrote: Hi Ross, I had a similar moment of worry when I looked at some of the ICs under an illuminated magnifying glass and just saw a blank top with, apparently, no ID markings. Then by accident, I slightly tipped the top face of the IC away from the light so the top was illuminated tangentially and voila - out popped the lettering in a faint silver glow. In my case, it seemed the silver lettering was very difficult to see if illuminated directly with a bright light source. Try gently re-orienting the IC under the light and see if you can make out the letters any better. 73, John VK7JB This email was sent from Netspace Webmail: http://www.netspace.net.au __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] Elecraft CW Net Announcement
Kevin. Oh for your temperatures. We here in North Carolina have been having a battle with the record for the most days over 90 deg/F. Right now, we are 10 days ahead of the record in 2007. Global warming speculation anyone?? 73, Don W3FPR On 9/4/2010 11:08 PM, Kevin Rock wrote: Good Evening, Another chilly week.

Global warming and Global cooling at the same time? WOW! Did someone come up with a weather machine and not tell us. 73 ES CUL John Klim N3KHK -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Don Wilhelm Sent: Saturday, September 04, 2010 11:47 PM To: Kevin Rock Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Elecraft CW Net Announcement Kevin.
