Re: [Elecraft] [K3] Tune Up of ALS-600
When you set the ALC on CW, this also sets the ALC for your peak SSB power. And you're right - you should adjust the ALC so it just comes on with the drive necessary to get your desired output. That being said, I don't use ALC. My ALS-600 needs about 65 watts to drive it to full output. Rather than mess with adjusting the drive and/or connecting up ALC, I place a relay-switched 2dB attenuator in-line with the amplifier. The attenuator automatically goes in-line when I turn on the amplifier so I can just leave my K3 set for 100 watts all the time. The attenuator is inexpensive and easy to make, and works great. Any full power transmit spikes related to a transceiver's ALC not acting fast enough on the first dit or speech peak will obviously not be there as the transceiver output is already at full power. This attenuator is described in the Articles section of my website at ww.ad5x.com.

[Elecraft] EPan and CW Skimmer
Ya know, even with the LPPAN SDR display up, my eyes are always on CWSkimmer anyway instead of the scope display. So if the EPan is stand alone, that's fine with me. Now if the K3 could just tell CWSkimmer what the IF shift is when changing roofing filters, and CWSkimmer would enhance their software to react to that change, things would be great. Even better, maybe the EPan unit will somehow make that information available. As it is, point and click in CWSkimmer doesn't work if the roofing filter changes. wayne/WA9VEE __ 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] K2 - No TX
Just wanted to update anyone on here who might have been curious. I believe I found the intermittant. In the process of doing the tranmitter signal tracing I found that the problem appeared to be between the pre-driver output and the driver input. With the RF probe I was seeing 6v (!) on the case of Q5 (should have been less than a quarter vrms) and only about 3mv on the base of Q6. So I reheated and added a smidgen of solder to those components, as well as T1 and C121.

Re: [Elecraft] [K2] K2 - No TX
From those measurements, you definitely had a problem between Q5 and Q6. Congratulations on finding it. The much higher than expected RF Voltages seems to mystify some builders - that is *not* a problem nor should it be cause for any alarm, but is normal behavior for the K2 power control circuits. When there is no (or lower than requested) power output, the K2 increases the drive in an attempt to generate more power. The result is that the RF voltage in the *working* stages will increase above the normal (expected) value - when you progress just beyond the failing point, the RF Voltage will drop substantially below the expected value - that should tell you that you just passed the failure point. It makes troubleshooting by transmit signal tracing a relatively easy task. 73, Don W3FPR djmd wrote: Just wanted to update anyone on here who might have been curious.

Re: [Elecraft] Need a kit recomendation (off topic a little)
You might look at the Softrock 40 small board. Great capability. It does have some SMT surface mount chips on it. I am sure you can get some help with them if you need to like I did for the first time. Small, cheap (was $10 in the beginning). It is a receiver or a single band or another kit I think has up to 4 bands and it sends data to the PC and decodes CW and audio SSB and even psk I think. The display looks like a spectrum scope and you click and it decodes or you hear the ssb audio. Neat. The K3 version (vs 40, 20 , 15, 10 meter versiond) can also be used as a spectrum display for the K3 I am told. 73,.

Re: [Elecraft] WD6DBM Builds for the Cycle
I can relate to that. A few weeks ago I had a complicated spinal procedure performed. Recovery is a slow process and the outcome will not be clear for a few more weeks. Last weekend the proper solution to my post-operative doldrums solidified in my head and I quickly ordered a K3 kit along with a KAT3 and KPA3.

[Elecraft] K3 160M Diversity Users
I am about to order filters for the K3 and need some final advice. I have the capability for diversity reception on 160 and 80 and am wondering what is the best filter pair to use for CW. Price really doesn't enter into the equation as a pair of matched 5-poles filters are about the same price as a pair of 8-pole filters. What are your recommendation if I were to get only one pair of filters? Is there any real value to getting a pair of narrow (200Hz or 250Hz) filters as well as a pair of the wider (400Hz or 500Hz) CW filters, or am I just wasting money? Is there a noticeable difference between the 5-pole and 8-pole filters? I would appreciate hearing from someone who has already gone through this and it would save me a lot of mental anguish!

Hey guys, another update on my tuner troubles.

I replaced it with a TL072 which obviously doesn't work since it is designed for dual rails. Long story short, I need an LM358 to replace it. Does anybody have an extra one they could send me?

Re: [Elecraft] New K1 on the way - Band Module Questions
Gary, The 4 band board cannot be modified much. The lower two bands must share the same low pass filter, so you are limited to 40 and 30. A low pass filter that would pass a 17 meter signal would be too close to the second harmonic of 30 meters to effectively reduce that 2nd harmonic. The K1, like all other transmitters must meet the FCC requirements for harmonic radiation. 73, Don W3FPR Gary W. Marklund wrote: I should receive my new K1-2 with KAT1 tomorrow or Monday. I ordered 40M and 30M for starters. I will add others shortly. My question is regarding modification for other bands. I've seen replacement parts lists for 12 and 10 M. Is there any reason the KFL1-4 is limited to 40/30/20 and 17 or 15? What if I wanted to build a four band module as say, 30/17/12/10 meters? Is there something inherent in the KFL1-4 that prevents this?

Re: [Elecraft] Need a kit recomendation (off topic a little)
Hi Alan, Please consider MFJ's 8100K regenerative receiver kit. It provides reasonable shortwave performance, and its regeneration control can be adjusted for ssb and cw reception. The radio's open layout makes it a good kit for beginners, and the $80 price includes a nice case. The kit assembly even requires the winding of one toroid. I used to teach an Introduction to Radio course for liberal arts students, most of whom had never before seen a soldering iron. They had a ball building these radios, and the few radios that did not work when first turned on were easy to troubleshoot. 73, John, no8v Original message Date: Fri, 24 Jul 2009 08:45:05 -0700 From: elecraft-boun...@mailman.qth.net (on behalf of Alan Price w1...@arrl.net) Subject: [Elecraft] Need a kit recomendation (off topic a little) To: Elecraft elecraft@mailman.qth.net I purchased an AM radio kit for my five year old grandson.

Re: [Elecraft] K3 160M Diversity Users
W4UM wrote: What are your recommendation if I were to get only one pair of filters? I would go with either the 500 or 400 8-poles. Is there any real value to getting a pair of narrow (200Hz or 250Hz) filters as well as a pair of the wider (400Hz or 500Hz) CW filters, or am I just wasting money? I have a 200 Hz in my Main in addition to 500 Hz 8-poles in Main and Sub. If you contest or are in huge simplex pileups, there are definitely times when the 200 Hz may be useful. For some reason I don't understand, I have no offset warbling when setting WIDTH to 200 (which enables the 200 Hz in Main and 500 Hz in Sub). Most of the time when listening to weak signals, I use 350-500 Hz WIDTH so a pair of 500 Hz filters is fine excluding the extreme cases of simplex pileups or a strong station nearby (e.g. the CQ 160 CW contest). Is there a noticeable difference between the 5-pole and 8-pole filters? I used 5-pole 500s in my first K3 and have not noticed a significant difference with the 8-poles, but I've not compared them simultaneously. As you stated, there's little cost difference (after the matching charge) so I went with the 8-pole 500 Hz when it became available. I personally prefer a slightly wider BW than the 400 Hz allows but that's another option some choose. You'll love diversity on 160 and 80, especially if you have good RX antennas. I use my TX antenna (similar to a 4-square) in one RX and Beverages in the other, and I use diversity 99% of the time on the low bands. I would never own any rig without diversity now that I've used it. 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/K3-160M-Diversity-Users-tp3322951p3323855.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] LP PAN and Point and Click and other threads (K3)
Just a gentle suggestion from a non-K3 guy. A while back it was brought up that we'd place the model # of the rig being discussed in the subject line of our posts, when applicable. Like, K3 when we were talking about that rig, or K1, etc. Threads of general interest would not have any specific identifier. The purpose was so that people not interested in the thread about a given model # could filter it out. I fully understand that another way to avoid this problem is to buy ALL of the Elecraft rigs so we'd have an interest in everything, but some of us haven't had taken that route (Yet :) ). So I'd respectfully request that we go back to that protocol as some have continued.

Re: [Elecraft] LP PAN and Point and Click and other threads (K3)
Lowly K2, Tom?? For me the jury's still out: my nice analog K2 or the very flexible and feature-rich digital K3. I'll probably never decide, just as I won't bother to decide whether 80 or 40 meters is a better band. They're just different, that's all. They do different things better. As for your suggestion, good point. From the e-mail reflector guidelines on the Elecraft web site: 4b. When emailing about a specific rig or option, please add the rig/option name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) This will be a huge help for those experiencing email overload and will allow automatic filtering based on subject line.

Re: [Elecraft] New K1 on the way - Band Module Questions
I am not sure if you are planning to change the two band modules often but if you are, I think it would be better to use an external tuner like the T1 rather than the optional internal tuner. It makes module swapping much easier. The K1 wasn't really designed for frequent module changes and its not just a matter of plugging a new one in, like with the Sierra. If you have the internal tuner installed, it needs to be removed to change band modules. I have often thought that if one could get along without the internal batteries, the speaker and the tuner, that there would be room for more bands on a larger board or multiple boards. But this would require switching changes to the firmware. Not something for mere mortals to play around with. Enjoy your new K1. I sure like mine. 73 Rick DettingerK7MW On Jul 24, 2009, at 8:13 PM, Gary W. Marklund wrote: Thanks, Sandy and Don. Looks like the two-band modules will give me the flexibility I want.

Re: [Elecraft] K3 160M Diversity Users
I am about to order filters for the K3 and need some final advice. Hi Mike. I have a pair of 400Hz and a pair of 250Hz 8 poles in my K3. I'm pretty active, 99% CW, and rarely use the 400Hz (maybe once a day) and very rarely the 250Hz (once a week). The DSP works extremely well. So of these, I'd recommend the 400Hz, and save up for the 250's later if you decide you need even narrower bandwidth than the 400+DSP can achieve. The 8 poles probably have a better shape factor than the 5 poles, judging by my experience comparing the 5 pole stock Kenwood filters with the 8 pole IRC replacements in my old TS850. With the DSP, I'm not sure you'd notice the difference but as you see I went for the better filters and don't regret it. On extremely rare occasions (e.g. fishing out CW callers in SSB QRM from Indonesian pirates) I have wound the filters right down to the minimum 50Hz and even at that ridiculously narrow setting, the K3 is a joy to copy with no appreciable ringing - miles better than the TS850 and indeed any other rig I've tried. I also use diversity with a 30m fullwave loop. Works great! I'm thinking of getting the AM and/or FM filters next so I can open up the bandwidth to listen to a whole chunk of band at once using an AF spectrum program: it sometimes helps to listen to all the callers in a pileup and to choose a clear slot to call. 73, Gary ZL2iFB __ 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
