Re: [Elecraft] KX3-2M module?
When driving a transverter presumably you will be running at 0dbm rather than at 5W. I wonder if the KX3 still experience thermal drift due to PA heating at very low power?

Re: [Elecraft] KX3-2M module?
OK, there has been a lot speculation but nobody has one yet to test. I both run JT65 on eme and WSPR on VHF and 600 meters, so I am fairly experienced in using these modes. I plan to rigorously test the KX3 + 2M for specs and test running these modes with real eme signals. I can run my K3 + 2m transverter (from another mfr) in parallel to compare performance receiving signals. I will test the frequency drift transmitting 3w. I have a EIP-538 mw frequency counter good to 26-GHz which uses an internal TCXO or external 10-MHz reference. I have a Rubidium reference oscillator with short-term stability of +/- 5 E-11 (that is 0.05 or 0.0005 ppm) to use as reference source. That will definitely measure the frequency accuracy and stability of the KX3 + 2M combination. I do not have a set up for measuring phase noise, but the parallel test described above will compare sensitivity using my K3 with TCXO-3/EXREF using an OCXO reference (be my phase noise reference). The OCXO is +/- 5 E-12 with Phase noise = -86 dBc/Hz, -118 dBc/Hz (100-Hz), -119 dBc/Hz (1KHz). I will publish my testing results on my website (I'll post the link when this is done). I also operate microwaves up to 10-GHz: currently have 1296-28, 3400-144, and 10,368-144 MHz transverters. All operate with an LO frequency about 1100-MHz and multiply to the frequency needed to mix with the IF radio. Example: the 10,368 MHz transverter uses an xtal LO = 189.33 MHz which is multiplied to 10,224 MHz and mixes with 144-MHz from the IF radio. the stability of the 189.33 MHz xtal oscillator is multiplied x54 and added to that of the 144-MHz radio. It should be obvious that the stability of the transverter LO is way more important since it gets multiplied. More and more PLL LO's are being used for this so the resulting LO frequency of 10,224 MHz is +/- 9-Hz. At worst case this is added to the +/- 10-Hz of the KX3+2M to provide a frequency error of up to 19-Hz. Wow! I think folks need to settle down and wait a bit until we can provide some independent testing before judging the merits of the KX3+2M. 73, Ed - KL7UW - Date: Tue, 8 Apr 2014 17:08:29 -0700 From: Wayne Burdick n...@elecraft.com To: Walter Underwood wun...@wunderwood.org Cc: Elecraft@mailman.qth.net Reflector elecraft@mailman.qth.net Subject: Re: [Elecraft] KX3-2M module?

But it's the short-term excursions within this range that would probably not work with JT65. Again, I haven't tried it. These excursions are due to the FLL (frequency-locked-loop) algorithm, which obtains data from an EEPROM table having increments of about 0.1 degree C (after calibration is complete). 73, Wayne N6KR 73, Ed - KL7UW http://www.kl7uw.com Kits made by KL7UW Dubus Mag business: dubus...@gmail.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 Message delivered to arch...@mail-archive.com
[Elecraft] KXPA100 et Smarttuner SG230
Hello, My configuration : KX3, KXPA100 (with KXAT100, not used in normal operation), coax line, SG230 (Smartuner), doublet.

[Elecraft] OT: Begali Paddles
When I upgraded to Extra, I bought myself the Begali Adventure Mono to go with my KX3. Needless to say, I have not been on *any* Adventures with my KX3 - yet. Mostly just taking it with me to work and using it during my lunch break. I like the Begali paddle I have. Currently, I have it in the shack on its magnetic base on a piece of steel I took from an old bent up Bencher key. Eventually I'd like to put it with my KX3 *only* instead of moving it back and forth. I'm not a *great* CW operator and I'm definitely *not* QRQ. I putter around 15 - 17WPM but I like nice CW tools. I'm looking to spend no more than $300 and am wondering about the Begali Simplex (which can be had for much less than $300). I have also looked at the N3ZN keys and they are very nice too. I actually had a ZN6 at one point, but sold it. Any thoughts?

Re: [Elecraft] KXPA100 et Smarttuner SG230
We have beta firmware for the KXPA100, now revision 1.28, that causes the KXPA100 to be much more tolerant of SWR and reflected power encountered while tuning an external tuner. As others have suggested, set TUN PWR to a low value between 5 and 20 watts depending on the needs of your tuner, but normal Tx power can be left at 100 watts. The KXPA100 won't tolerate without faulting really high reflected power (above 50 watts) or long duration reflected power above 20 watts or so. See the KXPA100 firmware page on our website. 73 de Dick, K6KR On Apr 9, 2014, at 1:50, Luc Favre luc-fa...@orange.fr wrote: Hello, My configuration : KX3, KXPA100 (with KXAT100, not used in normal operation), coax line, SG230 (Smartuner), doublet.

Re: [Elecraft] Line Out Jack
All, I was involved on this thread very early in its life because I had remembered having a transistor radio that had a mono earphone jack which wouldn't accept a modern 3.5mm plug. At the time, I thought it was a 1/8 in. jack. The radio was from Japan and it was made around 1959. I suggested that I might be able to find one in my junk box. Well, I went through my entire junk box, as well as a box containing earphones dating back to the 1930's, and found one plug (mono) that had a 2.5mm mono plug on it. Everything else was 3.5mm. Based on all of my searching, I believe that the old transistor radio actually had a 2.5mm jack, and not a .125 inch jack as I thought. I am also concluding that 3.5mm and 1/8in. plugs are the same thing since I have found no evidence that a .125 inch diameter plug has ever existed. If anyone finds one, please let us know!

My recollection is that 3.5mm and 1/8 have always been used interchangeably. I believe (guess) the discrepancy is simply that the plug originated as 3.5mm and 1/8 is the closest fractional inch (9/64 is unsatisfying).Checking specifications from one reputable manufacturer calls out sleeve diameter of 3.5+/-0.05mm for the plug and 3.6mm for the entrance of the jack. As with so many things, I'm sure there's no difficulty finding poorly designed/manufactured Asian parts that deviate.There's no such issue with 1/4 phone connectors.

Re: [Elecraft] Strange RFI question
Slava, I agree with Fred that this is noise from one of the many noise generating devices in our houses today. Square waves are generated by most every piece of electronics equipment in the house, and most consumer products make no attempt at containing them. We really haven't defended our spectrum from the local noise sources very well. The spectrum is actually pretty quiet in your location compared to mine. After about 10 years away from ham radio in the 80's, I came back and was surprised how noisy the spectrum had become. The addition of panadapters visually confirms what we hear. For relief, I occasionally carry one of my homebrew DC receivers away from cell phones, computers, etc. just to listen to the beauty of RF signals on a clear cold night. It is like the difference between fine wine, and Ripple!

I run an SGC 230 on my motorhome into a 33 foot telescoping antenna. I never attempt to tune the Smartuner running 100 watts. I always crank the power down to about 5 watts and tune. Then run the power up. I did the same with a KW rig I owned in an antenna restricted neighborhood in FL many years ago. I tuned a 25 foot commercial flagpole. Always low power first then crank it up. I wouldn't risk damage to my K3 even if the risk is small by dumping 100 watts into a non resonant antenna now matter how fast the smartuner works. At home, I have a SteppIR vertical and a SteppIR beam. I let the antennas tune themselves before ever putting any power out. Luckily, those antennas will change frequency with my VFO or computer or both running HRD without any RF involved.

But later, I was able to reproduce the issue and also fix without the factory configuration. I have the KX3 hooked up to Ham Radio Deluxe (latest version) with serial interface for CAT control. HRD works with the radio for the most part except I noticed this in the Radio CAT commands configuration - | Advanced: KX3 | RF power (High) | Cmd = PC-04, Min = 0.00, Max = 120.00, Prefix =, Suffix = | | Advanced: KX3 | RF power (Low) | Cmd = PC-04, Min = 0.00, Max = 120.00, Prefix =, Suffix = | Notice the Max = 120 part? Those values show up on HRD UI as - RF Power Low = 12 RF Power High = 120 There are two RF power adjustment bard in HRD UI. The RF Power Low slider works OK (has other issues) with the KX3 12 watt limit. But even touching the RF Power High slider causes the KX3 to switch RF power value to 110+ Watts (Yes, without a KXPA100, I wish). Once that happens, the ATU disengages and the radio refuses to transmit. The easy way to fix this is to touch the RF Power Low slider and the radio switches back to under 12W and everything goes back to normal. Shouldn't the KX3 itself handle this gracefully without tripping over the ATU with bunch of errors? I am a brand new HRD user and still getting used to the UI. I reported a major security issue to them a few days ago and will report this issue to HRD team as well. Comments / other ideas welcome.

Luc/Wayne, Yes. It does work fine. I have an SGC-230 connected to one of my antennas, also. The only suggestion that I can make is to make sure that the tune power is above the minimum required for the '230. If the SWR is very high before the system is tuned, the '230 doesn't quite make it all the way if you don't start above minimum required power. The sensitivity is primarily at the lower frequencies.

Re: [Elecraft] KX3-2M module?
I wouldn't be doing that for a couple reasons Stewart. I was advised not to by Elecraft in previous discussions. 1.Wideband transmitted Noise. Under driving the radio PA stageswhile they still have the same gain means that the S/N of the transmitted signal is reduced considerably, a bad thing especially if a high power amplifier is planned on the VHF and above bands where band noise is low and transmitter wideband noise will be heard over a wide area. 2. There are some gotchas with the KX3 and setting the output to a low value in the transverter menus. I have mentioned these before, but the ATU Tune button is dangerous as it will put out a lot more power than what is set in the transverter power setting in the settings! Danger Will Robinson! So, the only sensible and safe way to wire into an external transverter is to use normal HF power output and attenuate with a power attenuator it before the input of the transverter, wasteful in power and heat, but... So aftermarket KX3 PA heatsink and copper heatspreader for SI570 and extra calibration for VFO temperature may be essential for the highest frequency stability. 73 David Anderson GM4JJJ On 9 Apr 2014, at 08:24, stew...@g3ysx.org.uk stew...@g3ysx.org.uk wrote: When driving a transverter presumably you will be running at 0dbm rather than at 5W.

Re: [Elecraft] KX3-2M module?
Stewart, That's a good question. Certainly lower RF output will generate less heat. One issue that would need to be determined is whether the 2M module has any operating mode which would result in a full output spike which would likely destroy 0 dBm input circuit components. This has been documented for many non-Elecraft radios. But let's assume you can turn power to 0.1w at minimum (that is currently indicated on the KX3 PWR control). That would be 100mw or +20 dBm level. That can be attenuated to 0 dBm using a chip 50-ohm load or 20-dB attenuator (which I would be sure was rated for 3w - just in case). Design of transverter IF connections could either be common Rx/Tx or separate (preferred). If common, the transverter will have some sort of IF T/R control so load/atten. could be inserted on the Tx side. Inserting 20-dB attenuation on receive would affect receive sensitivity and possibly system NF. The circuit using a 50-ohm load would couple low power via a 10pF capacitor. You might need to have an adjustable drive level pot following this (make it an L-pad). With operation at this level frequency drift characteristics will likely by the same for Rx and Tx. I can test this concept when I get the 2M module for testing on my bench. 73, Ed - KL7UW -- Date: Wed, 9 Apr 2014 08:24:57 +0100 From: stew...@g3ysx.org.uk stew...@g3ysx.org.uk To: Dave d...@g0dja.co.uk Cc: elecraft@mailman.qth.net elecraft@mailman.qth.net Subject: Re: [Elecraft] KX3-2M module?

The mp3 file is a recording from the K3 in USB mode tuned to the center frequency. They are not all from my own LAN but mostly from my neighbors.

What number should I be setting mine at? Also, I assume that if I use my filters that it will limit the number of signals that CW Skimmer will hear. Any help would be greatly apprreciated.

[Elecraft] Rotten Signals
Dear Elecraft, We are in critical need of a device that will allow us to monitor our *actual* transmitted signal. There are so many rotten signals out there it’s pathetic. Since it would appear the offshore manufacturers are clueless as to the need for clean signals, perhaps pressure can be put upon them to clean up their acts by having increasing numbers of transmit signal monitors in the field. In any case I’d like to know that my signal is clean. The CWops contest last week was the last straw for rotten signals for me. For some time I’ve been using my P3 to analyze others’ signals. If I had a device that is similar in capability to the P3 to monitor my transmitted signal that might suffice. Here I’m thinking CW (spurs, clicks, synth noise…), but something that assists the op with transmitted SSB signals would also be of use. Likewise RTTY, etc. I don’t operate enough phone/RTTY right now to judge whether the P3 is sufficient to analyze one’s transmitted SSB signal. How about it, Elecraft? It seems the P3 has much of the needed function. You’d need some sort of coupler that was fast enough to capture high speed signals, while not passing a harmful amount of signal to the “P3T” (transmission monitor P3). Of course the P3T should easily handle 1500 W, not merely 500 W, to appeal to a broader market. Thanks for listening (I hope). 73, Gary W2CS __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] Configuring: KX3 -- KPA500 -- KAT500
I am planning on configuring my KX3 to use the KPA500 and the KAT500. Has anyone done this and what did you need to do? I already know how to hook up the KX3 to the KPA500 but would like to hear from someone using all three together. In particular, connections between KPA500 and KAT500. Also, follow up question -- if you have a configuration where you switch KX3 and K3 driving the KPA500+KAT500 do you disconnect any K3 involved AUX cables? I presume you would run with the K3 powered off if you are driving with a KX3.

Re: [Elecraft] Rotten Signals
Gary, The Sensor: input on the rear of th P3 is there for that purposehowever, the device has not been announced by Elecraft to date despite repeated requests. I too really do want to be able to monitor my TX signal, one of the disadvantages I have is that I operate Portable from my Motorhome 24/7 and as you can imagine, this constant changing of the station setup leads to mistakes or oopsies when setting up..:-) I also beg Elecraft to listen to our pleas 73 Gary On 10 April 2014 09:19, Gary Ferdinand alapa...@taconic.net wrote: Dear Elecraft, We are in critical need of a device that will allow us to monitor our *actual* transmitted signal.

Re: [Elecraft] Configuring: KX3 -- KPA500 -- KAT500
Phil, This should work well. You'll want to install the latest firmware on all units (use the beta if it's more recent than production). In particular, we recently updated the KXPA100 to be more tolerant of SWR swings when driving into an antenna tuner. 73, Wayne N6KR On Apr 9, 2014, at 4:23 PM, Phil Hystad phys...@mac.com wrote: I am planning on configuring my KX3 to use the KPA500 and the KAT500.

Thank you for all your replies to my email below. I have already summerised your input (of course, with credit and copy right to you) and passed to local ham societies for their reference. This is a great mail listing and I have been benefited from the learnt radio professions. Thanks a lot. 73 Johnny VR2XMC 寄件人︰ Johnny Siu vr2...@yahoo.com.hk 收件人︰ Elecraft elecraft@mailman.qth.net 傳送日期︰ 2014年04月4日 (週五) 11:05 AM 主題︰ OT: application of directional Quad in UHF Hello Elecrafters, It is off-topic and you can press 'DEL' now. Hong Kong is quite a hilly place in the rural areas. Local ham societies are often providing radio communication support services to charity organisations having fun raising sports activities in these areas. We have to set up UHF repeaters at the hill tops. Purely from the radio text books, a 3 element quad gives better performance than a 3 element yagi. However, I seldom see using directional Quad in the UHF repeaters. Apart from performance, are there any disdvantages (or advantages) of using directional quad instead of yagi in UHF repeaters? Could you share with me your experience in US? Thanks for your help in advance and please reply off-the-list to reduce the traffic in the mail listing (oh, yes, not forum!!) 73 Johnny VR2XMC __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Configuring: KX3 -- KPA500 -- KAT500
phil, I'm doing exactly that - I have a KX3 and a K3 that share a KPA500, KAT500, and several antennas. I went by the diagram in Fred Kady's book on the KX3. Works like a charm. I can get up to 250 watts out with the KX3 driving the amp at 12 watts. And, no, I do not disconnect anything when I want to use the KX3 with the amp and tuner. Just make sure that (1) the K3 is powered off if you are using the KX3, and (2) your coax switch connecting the two radios to the amp has very good isolation.

Most modern rigs have a monitor function lets the operator listen to his transmitted audio, and I'd bet that many of those who sound the worst have another rig that the COULD use to listen to their own RF signal. 73, Jim K9YC __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] Rotten Signals
I like the CQ messages with a different voice that comes back to you. Usually the CQ message from a certain area is really bad sounding but the real ops sound much better. Sadly I believe many intentionally distort their audio to make their signals wider. Mike W0MU On 4/9/2014 11:09 PM, Jim Brown wrote: On 4/9/2014 6:56 PM, Milverton M.

[Elecraft] Audio interface issue.
I have blown up computer motherboard audio line inputs on three computers and two USB audio adapter dongles trying to run RTTY or PSK. The Line Out is set at nor 15. There was a direct connection from Line out to the rear sound line in.There is a large ferrite 51 mix choke on the cable. There was a ~20dB pad in line going to the mic input on the dongles. The antennas are 150' away 75' up, and I am running 500W. The line output is transformer-coupled, right? It appears there is some sort of transient that's killing the input to the audio codecs. Does anyone have experience with this problem? -- Dick - N7XU __ 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 Message delivered to arch...@mail-archive.com
