Re: [Elecraft] RFI With KPA500 Full Output on 40m
One or more of the wires going to your system must be resonant on 40 meters and is picking up RF directly from the antenna. I had horrible problems when I had an inverted L with the horizontal part over the house. My alarm is a 'wired' type that has terminating resistors at each of the switches. 1.5 kW on 160 meters simply vaporized one of the resistors, and heated others at the alarm box. I fixed it by winding each of the wires going to the switches around ferrite cores at the alarm box. I also treated the phone line and the wires that go to the battery and the bell box. I used various cores, but the square Radio Shack things worked. No. 31 ferrite mix is recommended. That fixed it, but I replaced the inverted L with a T and got rid of a lot of RF floating around. Since all of your lights are lighting up, I would start with the phone line and the power supply. Remember, at 40 meters you need to as many turns as you can get around the cores. Just passing the wire through a bead won't do it. On 3/17/2012 8:51 PM, Jim Bennett wrote: Just when one thinks all is good in the world...

[Elecraft] (OT) Recommendations for Testing
Ed your SDR-IQ will do a nice job of close in 2 tone ID testing, a better job than my simple spectrum analyser. For IMD testing you do not need a resistive coupler, an ordinary oscilloscope probe used with a couple of turns of wire around the output coax outer will provide sufficent signal for IMD tests (it is not suitable for power measurement or harmonic measurement). I have sent you via direct email a screen shot of my K3 and KPA500 2 tone IMD test viewed on a Perseus SDR. It allows simple and easy measurement of each tone and you may be able to make similar measurements with your SDR-IQ. For harmonic measurement the bar is raised a little. You need a means of sampling via a resistive coupler and/or high power attenuator. The attenuator can be very expensive... The simple wire loop coupler which works for narrow IMD measurements is not likely to have a flat response across the HF and VHF spectrum. You will also need a conventional spectrum analyser for harmonic measurements, although you do not need one of the high cost narrow bandwidth ones... One of 15 ~ 20 KHz bandwidth will suffice. There are several on the market for $1500 or maybe less. I have a TTi PSA1300T hand held analyser which sells for $1500 from Newark which is based on a Palm TX PDA and offers the ability to take screen shots and store them on a memory card. There are several low cost analysers from China on eBay (around $775 plus import charges), however I have no experience of them. 73 Dave, G4AON __ 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] RFI With KPA500 Full Output on 40m
Hi Jim, I think it may be a fact of life with alarm systems since they have wiring all over the house. On mine, high power would signal an alarm identified as a fire alarm. I identified the wires in the alarm panel that went to the smoke detector input screw terminals and added a clamp-on ferrite core. Problem solved. In your case you should identify the cables (probably 4 or 5 conductor) coming from the alarm keypads and clamp on a core on each one. Anybody with an amplifier should probably have a supply of clamp on ferrite cores. Odd things start to happen as you approach legal limit. My heated matress pad would start blinking also on 40 meters. I had to use a larger diameter split core and wrap the AC power cord for the matress pad controller through it several times to solve that one. 73, Mike K2MK Jim Bennett wrote Just when one thinks all is good in the world...

Re: [Elecraft] RFI With KPA500 Full Output on 40m
I had similar issues over the years with my GFI receptacles. I put ferrites on the power leads both at the receptacles and in the main distribution panel but was only able to reduce the problem and/or move it to other bands. I then tried different brands of receptacles and, after trying everything from Lowe's and Menard's, finally found that the Leviton brand GFI receptacles (I found them at Home Depot) completely eliminated my problems.

The web site for SGC does not show any particular expertise or make any claims for purity of signal. Maybe they are great, but I am not convinced.

Ferrite chokes work by adding a parallel resonance in series with the wire that they surround, and a single bead or clamp-on is resonant around 150 MHz. To make it useful at HF we must move the resonance down to the HF bands by winding multiple turns through it.

[Elecraft] RFI With KPA500 Full Output on 40m
I live in a single family townhome (house with lots of HOA rules) and a fan dipole in the attic. With the dipole oriented NW-SE, it was right over my radio controlled garage door opener. Operation at 100 watts on any band would turn on the light, but on 40 meters the door would try to go up and down with my CW keying. The wiring to the opener couldn't be worse from an RFI standpoint - two wire unshielded all over the garage walls and ceiling. I wound up with what we call the trivial solution in math - moved the dipole to NE-SW and now 40 meters only turns on the light. Not sure what there is about 40 meters but that is also the only band that caused a little TVI on one of the TVs as well. The XYL was not amazed! Similar lack of humor to when I had a SB220 linear running parallel 450 feed to a G5RV and turned the call ID units into French! Instead of unavailable it came up with hors de .

Re: [Elecraft] KX3 and Data Mode Interface
This seems a popular topic on the KX3. For computer interfacing the KX3 for running various soundcard programs a simple interface is needed for PTT, Keying, and transmit audio. It is assumed that one side of the IQ baseband will serve for connection of Rx audio to the soundcard. A couple choices are given for PTT: 1) using the Mic-PTT 2) using GPIO input Transmit audio from a soundcard will have to be: 1) isolated 2) reduced in amplitude to drive the mic input properly. RS232 needs to be isolated from KX3 PTT and KEY. An external unit is what looks practical and will need the proper connectors: 1) Four contact mic connector w/ suitable length cord 2) ACC2 connector (if used) 3) standard 3.5mm phone jack for soundcard interconnect (get that from RS) 4) breakout of serial cable RTS line and DTR line 5) connector for KX3 KEY jack. 6) transistors to isolate RTS and DTR 7) resistive divider (pot) for setting Tx audio level 8) miniature pcb isolation transformer for audio A simple interface can be made very tiny using sm components, though may be more than will fit the standard DB9 (9-pin subD) jack shell.

Re: [Elecraft] KX3 and Data Mode Interface
Hi Ed, I also need the same thing, as I am sure many people do. I need to figure out a solution as small as possible, since my KX3 and whatever additional cables/interfaces/6m preamplifier, etc etc. need to all fit in the outside pouch of my laptop computer case for airline travel. Any thoughts would be greatly appreciated. I would THINK that Elecraft probably would provide cables (eventually, anyway) to allow the KX3 to be used on digital modes, but maybe it will take some time after the production units are actually going out the door. I would have expected that field testers already would have determined the best way to achieve this type of operation, Ed. So I think it is best to let the dust settle first and get their input before rushing off to develop some custom interface that may or may not be necessary with the final KX3...

Re: [Elecraft] (OT) Recommendations for Testing
Ed, A very important consideration when measuring the IMD performance of an amplifier (or certainly a receiver), is that the level of any intermodulation products generated by the test equipment must be low enough so that they do not introduce measurement error. Among the usual sources of these rogue IMD products are the spectrum analyzer (for sure if is overdriven), the combiner used to combine the two test tones, and the harmonics generated by the two test tone sources - all of which can be muzzled. Of course the better the IMD performance of the DUT, the more significant is the the error introduced by any test equipment generated products. If you will bear with me (it is late here), and if of any interest to you, I can send you off list later today more detailed information. 73, Geoff LX2AO On March 17, 2012 at 20:19 +0100, Edward R. Cole wrote: I will be testing some amplifiers, soon, and would like advice or links to info on making IMD and harmonic level tests on HF amplifiers. I can generate two-tone modulation and monitor spectrum up to 196 KHz width with my SDR-IQ, but do not have a spectrum analyzer. I have a scope, power meters, 500w coaxial load, XG3, and a couple DMM, plus analog 30v and 30a dc meters.. 73, Ed - KL7UW, WD2XSH/45 __ 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] K2 Update Process?
I finally joined this elite group of Elecraft owners by acquiring a used KX1 a month or so ago, and a used K2 last week. My K2 has a few options already included, but since it's an older unit (#656) and is running firmware 1.02, I'd like to upgrade everything to make it current. Here's what I have: K2 #656 v1.02 KAF2 Audio Filter and Real-Time Clock; Revision A, August 30, 2001 K160RX 160 Meter Module; Revision A, September 8, 1999 KSB2 SSB Adapter; Revision A, Oct. 11, 1999 KNB2 Noise Blanker; Revision B, Nov. 4, 1999 KAT2 Automatic Antenna Tuner; Revision B, Feb 14, 2000 I'll continue to review all the information on the Elecraft website, but it IS a bit confusing with all the permutations over the years. Is there an obvious simple way to upgrade the unit, e.g., just replacing the firmware chip, or does a lot more need to be done with all the options? I don't plan on getting the 100w option, but I suspect I WILL upgrade and get the RS-232 and USB adapters for it. Ideas/thoughts? Thanks.

Finally, I hit the power switch to turn off the rig. That can't be too good for the radio The rig is working fine on regular SSB transmissions. This has happened twice.

Re: [Elecraft] KX3 shipping status update
Just part of manufacturing and production engineering. :-) We had 4-layer boards [signals on the outside, pwr and gnd in the middle to cut down crosstalk], and in the prototypes, multiple thrus got plated to the inside layers. Hey ... prototypes ... we used a couple of marine 12V batteries and burned the plating off so we could use them for testing. The board house sweated the bullets and fixed it for our customers. I've always thought the design engineers should spend some time with the manufacturing engineers. Just because you can think it up doesn't mean you can make it, in quantity, at a profit.

Re: [Elecraft] K2 Update Process?
Bill, Go to the Elecraft Order page on their website and surf to the K2 Spare Parts and Mods section. From there, your point of interest is the K2 A to B mods. Order all within that A to B list and also order the K2KEYMODKT. That will get your K2 up to date. Since there was a change in the crystal specs that occurred at SN 2560, I also recommend that you order the set of 14 matched crystals (if you do not have the KSB2, you only need the set of 7). 73, Don W3FPR On 3/18/2012 10:39 PM, Bill Tubbs, WK6A wrote: I finally joined this elite group of Elecraft owners by acquiring a used KX1 a month or so ago, and a used K2 last week.

Here's what I have: K2 #656 v1.02 KAF2 Audio Filter and Real-Time Clock; Revision A, August 30, 2001 K160RX 160 Meter Module; Revision A, September 8, 1999 KSB2 SSB Adapter; Revision A, Oct. 11, 1999 KNB2 Noise Blanker; Revision B, Nov. 4, 1999 KAT2 Automatic Antenna Tuner; Revision B, Feb 14, 2000 I'll continue to review all the information on the Elecraft website, but it IS a bit confusing with all the permutations over the years. Is there an obvious simple way to upgrade the unit, e.g., just replacing the firmware chip, or does a lot more need to be done with all the options? I don't plan on getting the 100w option, but I suspect I WILL upgrade and get the RS-232 and USB adapters for it. Ideas/thoughts? Thanks.

[Elecraft] P3 at 115,200 baud
I can't find it now, but someone posted something showing a screen capture with the latest P3 f/w and Utility running at 115,200 baud rate. I'd like to know how they got the K3 to go that high? Mine tops out at 38,400 using 4.39 f/w. Richard Fjeld, n0ce rpfj...@embarqmail.com I'd rather be learning. __ 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
