[Elecraft] K2 S-meter calibration (CW-CWRV-USB-LSB) ?
Hi K2 builders; I do have calibrate my S-meter following exactly what is tell in the building manual. I do have done this allignement CW normal mode. What I see while switching between CW reverse and USB and LSB mode is that the right led indication does not indicate most right on other modes ??? I see a little difference in S-meter indicaton bewteen CW normal and the 3 other modes ?? The S-meter indicaton is dropping one led from right. The most right led indication is done with RF control fully counter clockwise of course. Is this normal,I do have allign my filters and BFO settings all correctly. Yes I now,I am talking about details now,and what I see while playing with my new toy hi. Next days I start to build my KPA100 unit. Great building kit for sure...

Re: [Elecraft] Noisy RX redux
Hi Mike, For those wondering what Mike found. There are two ways to go. A complete DSP board swap or a DSP board modification. K3DSPUPGD for $109.95 (this is the board swap) or K3DSPLPF for $39.95 (this is the board mod) Both items can be found here: http://www.elecraft.com/order_form_parts.htm Serial numbers might not be the best clue for those buying a previously owned radio. The previous owner might have already made the improvement. 73, Mike K2MK Mike Reublin wrote I found the mod.

Re: [Elecraft] KX3 Receive Noise
Try going into the menu and turning on the RX I/Q out. I noticed on my kx3 with the latest firmware, there is a sharp hum and audio distortion while the RX I/Q out is disabled. The noise is so piercing I can't use headphones with it.

Re: [Elecraft] K2 S-meter calibration (CW-CWRV-USB-LSB) ?
Jean, You can adjust the CAL S HI menu in CW reverse or LSB or USB to compensate for that discrepancy. If you have a signal generator that produces a 50 microvolt (-73 dBm) signal, use that to adjust the CAL S-HI menu parameter. 73, Don W3FPR On 7/5/2013 4:30 AM, Behiels JeanPierre wrote: Hi K2 builders; I do have calibrate my S-meter following exactly what is tell in the building manual.

[Elecraft] K1 TX output low on 2 of 4 bands
My K1 (#1066, built 11 years ago) is a four-bander with ATU and internal battery pack. In May I built an Elecraft W1 wattmeter and used it to discover that my TX output (When Out in the menu is set to 7.0W) is only 1.2W on 15 meters. At that time, all other bands showed an output of 5W. However, last night, after an afternoon of using my K1 while fruitlessly trying to tune up a new antenna, I noticed that the output on 20 meters was also now down, measuring 1.5W. I strongly suspect that a component failed due to TX'ing into high SWR while trying to adjust the antenna I was working on. 40 and 30 meters still seem to be okay. (My guess is that 15 is low for the same reason--I just didn't discover it in a timely fashion like I did with 20 meters). So, anybody have a suggestion for where to start with troubleshooting? Should I suspect the filter board? Any components in particular?

Any RF board component failure would affect all four bands, not just 20m and 15m.

This definitely has NOT happened to your K1. Rest assured then that nothing was hurt on your K1 during your antenna tuning efforts. When some bands still function well, but others do not, it is a certainty that the problem is on the filter board. You have an older K1, and possibly an early KFL1-4 filter board. The 16 trimmer capacitors that are on the KFL1-4 were originally white-body capacitors that were very prone to spontaneously changing their effective value. A couple of years after the KFL1-4 was introduced, Elecraft changed all 16 trimmers to a much more stable design with a light blue body. Look at the four rows of trimmer capacitors on your KFL1-4, which are easily observed from the back of the K1 even without removing the KAT1. If they they do not have light blue plastic bodies, then you have the old troublesome original trimmers in place. You'll need to get the replacement trimmers and install them. Those are almost certainly the source of your problems. OTOH, if you have the newer blue-body trimmers, you will still want to re-align your KFL1-4 to restore full output. In fact, you'll want to do that if you have white trimmers, just to verify that output can be restored in the interim before change out. When I still had those old trimmers on mine, I needed to re-peak 15m and 20m on my KFL1-4 every few months due to the drop in output power I observed. So did a lot of other people. After such results, Elecraft supplied a set of 16 blue-body replacements. It was *not* a lot of fun removing 16 trimmers and replacing them, but it was worth it. I recently re-peaked my KFL1-4 after more than eight years since last performed, and found essentially no pre-peaking degradation. 73, Mike / KK5F __ 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 Antenna Tolerance
Hello Tom, I've just finished my K2 bare bones, and would like to get on the air. What SWR will the finals tolerate without harm? I'm using a ground mounted trap vertical I have used my old K2 (#01118, modified for 5 watts output) also without an antenna, but without deletions of the finals, so the SWR was infinite. But if you use the upper output limit of your K2 this operation mode could be deadly. -- 73/72 de Ingo, DK3RED - Don't forget: the fun is the power! www.qrp4fun.de - dk3...@qrp4fun.de __ 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] OT P3 video of RFI, ideas?

Video recording: http://www.flickr.com/photos/ak5x/9214448105/ It is not always there. When it is there in the 20-meter band there are siblings almost as strong at the following frequencies: 13.975 14.032-the recording 14.126 14.220 14.282 14.469 In addition, there are less strong signals that follow the pulsation; one is visible on the recording at 14000 (far left on the P3). They are also in the 17 meter band. They are not in the 15 meter band or above. I have pulled the big switch and it is still there on battery power. My suspension is a neighbor with plasma television. Is this what plasma TV looks like?

Re: [Elecraft] OT P3 video of RFI, ideas?
Rick - I put a couple big clamp-on's on the power cord. No help. The only other cable going to that TV is a heavily shielded HDMI cable from the Denon A/V unit. From what I understand, the RFI is generated in the plasma cell area, and not on any cables. I may be mistaken, but I believe the best way to suppress plasma TV generated RFI is with a 12-gauge shotgun. And, believe me, if (1) it was legal, and (2) not so expensive - I'do just that to ours!!! :-) :-) And, no - don't do that to your neighbor's TV!! Actually, that Samsung TV gets little use these days. Our main TV is a 65 Panasonic Viera plasma set that surprisingly generates no RFI crud.

Re: [Elecraft] OT P3 video of RFI, ideas?
The plasmas were not really 'outlawed' - but California made sales there a problem because they are rather inefficient users of electrical power. (As in close to a KW to create a picture on early models.) - That said, their picture is usually vastly superior to the LCD sets, even those with LED backlights.

Re: [Elecraft] OT P3 video of RFI, ideas?
Bill, I have a 50 inch Panasonic plasma and when it is on, lower bands 40 meters and below are near useless. It causes some problems for me on 20 meters and up but it gets less as the bands go up. My P3 display is similar to yours. Otherwise it’s a great TV, great picture. I have tried several things but only thing that has helped, especially on 20 meters and above is to move ham antenna further away from my house.

Re: [Elecraft] OT P3 video of RFI, ideas?
In the UK there has been a great deal of interference caused by plasma screens. The QRM is radiated by the screen and gets worse with age as the power to the backlight increases to compensate for reducing emissivity. Recently Panasonic, the main culprit, have been replacing plasmas with their latest LCD model that have much better pictures and no rfi. Current LCD models now have much improved performance and have better pictures that the plasmas that are now being phased out. A campaign has been waged by concerned amateurs and details can be found at http://www.ukqrm.org.uk/ Best of luck 73 Peter G3SMT From: WM3M w...@live.com To: Bill Hammond wham...@aol.com; Elecraft Reflector Elecraft@mailman.qth.net Sent: Friday, 5 July 2013, 17:45 Subject: Re: [Elecraft] OT P3 video of RFI, ideas?

Re: [Elecraft] OT - anyone have experience with effects of metal roofs on antenna performace?
SWR is a pretty coarse indication of interaction. Interactions can change directional antenna F/B and F/S ratio by 6-10 db easily (assuming you have it in the first place) and hardly affect SWR. At least, this is my experience from antenna modeling. However, we have to live with the hands we're dealt. Without any field strength measurements or calculations, one probably won't detect much. Ignorance is bliss. 73 de Brian/K3KO On 7/5/2013 20:13, Ignacy wrote: I had verticals on concrete, roof shingle and metal roofs. Always radials lying on top. The metal roof was the best by far.

[Elecraft] Custom 700 Hz 8-Pole INRAD Filters--You Should Get in Queue!
Hi Everyone, I recently purchased and installed the 700 Hz Custom INRAD filter from Gary-KI4GGX of www.unpcbs.com. In the nearly two weeks that I have had this filter installed in my K3, it has become my primary CW filter for this rig. I am not a contester but rather a search and pounce DXer for many years now (35+). My first rig as a novice was a Heath HW-8 in 1977. It was a QRP CW rig running 2-3w CW with an audio filter at 750Kz. I worked 38 countries with a dipole with that rig. It taught me to learn to listen for CW DX using a broad filter bandwidth compared to most of the standard bandwidths used these days. I have been using an INRAD 8 pole 500 Hz CW filter in my K3 since I got it in 2008. But I had been thinking about Gary's 700 Hz filter for a while now and I finally decided to take the plunge two weeks ago. For me this had turned out to be the perfect CW filter. I find myself using it exclusively now in all but the very most difficult situations. (Remember I do not contest.) It allows me to cruise the CW bands from a wider perspective helping me to gain a more macro-orientation to what's on the CW bands and making me use my brain more to differentiate between the CW signals I hear. It's a very comfortable filter to listen to. For me this filter is a keeper here for sure. As for Gary and unpcbs, both remind me of an extension of Elecraft. Excellent quality product with superior service on top of that. If you are thinking of pre-ordering with Gary for an upcoming INRAD Customer 700 Hz filter batch, I can highly recommend that you do so. I really like this filter.

Re: [Elecraft] K3 es AIRMAIL
Airmail is one software and RMS express is made by the Winlink group. I use RMS express with my K3 and my K2 and KX3. It works fine business on Winmor. Hope that helps.

Re: [Elecraft] K3 es AIRMAIL
NAVMARCORMARS (Navy Marine Corps MARS) uses RMS Express with Winmor for MARS message traffic. It works very well on HF AND Winmor TelNet. I use it with a K3 with NO problems. It supports K3 interfacing for rig control. If HF communications are poor due to solar storms, etc., it can be used to send messages via TelNet.

Re: [Elecraft] OT - anyone have experience with effects of metalroofs on antenna performace?
This note is for the log/web manager. I note that each time somebody comments on a thread ( the recent ones on metal roof), a new email is sent to all recipients. This is a nuisance cluttering the inbox. My experience with blogs is all comments are retained on the server Under one heading, and an email is sent daily to anybody interested in that subject upon request. Hope something could be done about that.
