Re: [Elecraft] K2 SSB audio distorted. Realignment, MIC gain mod etc.
Don, Your suggestions worked. I tucked the wires better away from the KSB2 and replaced R2 back to its original value (VOX is now unusable, but I am fine with it). The distortions are gone with SSBC 1-1 and signal gets a little distorted with more compression but that is normal I think. I noticed that there is quite a different of RF levels between different bands with the same mike. I am considering doing the other SSB mods as you suggested from http://www.qrpproject.de/Media/pdf/SSBModsUK.pdf. It seems that these mods will help with the level difference on different bands. Thank you so much for your help.

Realignment, MIC gain mod etc. Andreas, Yes, do tuck those cables up and away from the KSB2 board. The value of R14 may be OK, but I worry about the 1k at R2, that should be 5.6k so not to overdrive the balanced modulator. In addition to that, you might also put a 2.2k resistor between U5 pins 1 and 2 (it is easiest to mount on the carrier balance trimmer, it goes across the two outer leads - not the center lead). The VOX on the K2 is the one thing that is not the best. If you can use PTT rather than VOX, you will obtain better performance. 73, Don W3FPR On 1/4/2012 2:51 PM, Andreas Hofmann wrote: > Thank you very much for the information Don.

Re: [Elecraft] Amazing!
Hi Mike, That may be true, however, I don't use dipoles because, I can't. This is where a mag loop has an advantage. I dipole needs to be up high and have two supports unless set up as a inverted v. I don't have trees or towers in my yard. My girlfriend has trees but, if I were to put up a dipole, I'm sure there would be a knock on the front door. I can work multiple bands with a mag loop without a tuner and the neighbors can't see it because, it's below the fence line. I can also rotate it. When I lived in another location, I had a tower. I had a rotatable dipole on it. It worked great. I ended up using mostly inverted vee antennas because, the wind didn't bother them as much and they didn't need to be rotated. Plus, I didn't like climbing a tower. ;-) 73, Gary, N7HTS > I'd suggest trying a simple dipole. A 15m dipole is only 22 feet >end-to-end, > and it is very easily set up almost anywhere.

Re: [Elecraft] Amazing!
Ignacy, I agree. That's why I like mag loops. I've built three of them and I'm getting ready to build a forth. They are quieter than my home brewed 30' multi-band vertical and I can pick out signals a little better when band conditions aren't so great. Add the quiet K2 and signals pop out of nowhere.

Re: [Elecraft] Another KPA500 question
I will be a the Orlando Hamcation in Commercial Bldg. 3 Booth 304 with my new switch box 6 rigs and relays to two amplifiers. The switch is designed for 100 watts exciter RF power and as such there is not much chance of RF coupling between rigs. I used a 100mw QRP watt meter connected to AMP 1 while driving AMP2 with 140 watts RF on 40 meters I couldn't see any deflection of the QRP watt meter during this test. I will do more extensive tests while I receive the production boxes. I have been using my prototype switch (the one on my QRZ page with my K3, TS-520S, K2 and TS-870 for over a year now without any RF issues. The new box is much more rugged than the prototype. You can see the prototype switch installed at W3JCB and AC4Q on their respective QRZ pages. Both ops have had no problems with RF coupling. Let me know if you have any further questions or comments. 73's Jerry Henshaw KR5L -- View this message in context: http://elecraft.365791.n2.nabble.com/Another-KPA500-question-tp7134629p7152311.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] K2 SSB audio distorted. Realignment, MIC gain mod etc.
Andreas, Yes, do tuck those cables up and away from the KSB2 board. The value of R14 may be OK, but I worry about the 1k at R2, that should be 5.6k so not to overdrive the balanced modulator. In addition to that, you might also put a 2.2k resistor between U5 pins 1 and 2 (it is easiest to mount on the carrier balance trimmer, it goes across the two outer leads - not the center lead). The VOX on the K2 is the one thing that is not the best. If you can use PTT rather than VOX, you will obtain better performance. 73, Don W3FPR On 1/4/2012 2:51 PM, Andreas Hofmann wrote: > Thank you very much for the information Don.

Many "tips" that have come in over the years have been incorporated into the K3 Kit Assembly manual. Build the K3 just like you walk, one step at a time, and it will go right together. At this point a great many K3 kits have been assembled quite successfully by very average Hams, some as their first kit ever. 73, Ron AC7AC -Original Message- The YouTube video is cute but not sure it is really helpful.

[Elecraft] Amazing!
I thought I would share my story of what happened over the holidays. I live in Cheyenne, Wyoming but, spent most of the week before the new year in Fort Collins, CO. My girlfriend lives there. We have been dating for about seven years now and she suggested that I bring one of my HF rigs and operate from her house. I don't know why I had never thought of that before. I took my K2 and a home brewed magnetic loop antenna. The mag loop is about three feet in diameter and sits three feet off the ground. I set it up in her back yard which is pretty much surrounded east and west by her house and the neighbors house. I operated mostly 15 meters and some 17 meters at 5 watts QRP. One morning I fired up the K2, set it for 5 watts and started calling CQ. A faint signal came back. It was a ham in Scotland!!! For those of you that have beams, it's probably no big deal. We were both running 5w and he was using a K1. I also worked two French stations that morning, all QRP with a mag loop three feet off the ground. I know that most of it has to do with propagation and the antenna. In this case mostly propagation. At least that's what all the books say. Theory, theory, theory. I say to heck with theory! I experienced something beyond theory! It was MOJO!!! So stick that in your theory pipe and smoke it. ;-) Why is it that when I'm working with my K2 or K3, most of the responding stations are also using an Elecraft rig? MOJO! MOJO! MOJO! That's my theory.

Re: [Elecraft] Trying to get to grips with the KDSP2 Filter
Ray, Think about how you are going to operate with data modes, and how you have the RTTY filter set aligned (or will align it) - that will tell you how to set the KDSP2 RTTY parameters. If you will always use the full SSB filter width passband when using digital modes, perhaps the RTTY filters that are set as default are OK for you. My recommendation is that you set the RTTY IF filters to widths of OP1, 1.00, 0.70, and 0.40. Set the passband for the OP1 filter the same as you have for SSB, and center the passband for the more narrow filters at 1000 Hz. Then set the center frequency of the KDSP2 filters to 1000 Hz. In use, tune the desired signal to the vicinity of 1000 Hz in the waterfall display so you can switch in the narrow IF filters and/or the DSP filters to reduce QRM. Why choose 1000 Hz for the center (you might ask) - well, the K2 BFO has enough range to allow that frequency, but not much higher. Also, MMTTY has a mark frequency setting of 910 Hz that works with that center frequency. 73, Don W3FPR On 1/4/2012 10:13 AM, Ray G3XLG wrote: > Thanks Ken& others who replied directly.

Re: [Elecraft] Fwd: Re: KX3 Display LEDs
Good morning Igor, You are correct, to a point. When you have a thousand units of weight, in Spanish, you do NOT say you have "Kilo Kilos of X". You say you have "mil kilos of X". Likewise, when you travel a thousand units of distance, in Spanish, you do NOT say "Kilo Kilometros", You say "mil Kilometros". Milli is used as a prefix for terms to indicate 10 to the minus 3rd, but mil is used as a separate word to indicate 10 to the 3rd.

Re: [Elecraft] K2 4MHz Adjust...
I suggest you use the N6KR method to set the 4 MHz reference oscillator. Refer to my website www.w3fpr.com article on K2 Dial Calibration. Note that the actual frequency may not be at 4 MHz. You may use any AM station that has a known carrier frequency rather than WWV. If you use a standard station that transmits only a carrier, you will still have to use SSB mode, but switch to CW to adjust the pitch equal to your sidetone pitch. 73, Don W3FPR On 1/4/2012 8:38 AM, EB1TR wrote: > Hello to all, this week (my last hollidays week) I thought it would be a good > idea to adjust the oscillator 4MHz my K2. > > I performed the steps as it is described in several ways but the result is > always the same. > > 40 meters LSB 200Hz shift > 40 meters USB 1.5KHz shit > > In other bands the results are always similar.

Hello to all, this week (my last hollidays week) I thought it would be a good idea to adjust the oscillator 4MHz my K2.
