[Elecraft] Remote operation of a K3
Hi all; I would like to remote my K3 station via the internet. With out spend lots of money. I know there are several programs available that clam remote operation but they don't tell you what else you got to buy. Back in the 90's I used a program called PC anywhere to access my office computer from any where it worked fairly well. An I see it still available is anyone using it to access your host computer in your shack? I am open to suggestion from anyone who has a K3 up and running, One more thing I am disabled an right now I can get out to my shack via a wheelchair, But I done know when I will be confined to my bed most of the time, An before that happens I would like to get the K3 station remoted. Please all suggestion keep off the reflector and answer me direct at w0...@yahoo.com .

Re: [Elecraft] KX3 - ATU Disabled Problem
I have no KX3, nor do I walk on water. I just googled d = 000, ERR TxC, ERR TXS: Out popped a reference to the KX3 Users Manual: I searched the KX3 Users Manual manual says: ERR TXC, ERR TXS: Transmit attempt without first calibrating TX BIAS in CW (TXC) or SSB (TXS) mode Perform Transmit Bias calibration (pg. 33). This is a fully-automated procedure that requires no test equipment I would go to pg. 33 of the KX3 users Manual and Perform and read the transmit Bias calibration. I then search this list for "transmit Bias calibration". That was interesting. Quite a few posts.

Re: [Elecraft] KX3 - ATU Disabled Problem
I wonder if this might be the problem !!! There is a very interesting post with the title: "KX3 production firmware update, rev 0.97 -- very important bug fix, better CW QSK, etc." KX3 production firmware rev 0.97 (with DSP rev 0.84) is now available. It corrects a problem in the power-on/off sequence that could inadvertenly modify EEPROM locations (that is, operating parameters). It has other significant improvements as well. See recent release notes below. ... * EEPROM DATA INTEGRITY IMPROVED: Previously, in rare cases one or more EEPROM locations could be modified during power-on/off cycling. Symptoms included “ERR TXC” or “ERR TXS” messages, AGC turned off, etc. -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-ATU-Disabled-Problem-tp7586823p7586828.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 Message delivered to arch...@mail-archive.com
[Elecraft] KRC2 and TS480
Hi everyone, I have KRC2 band decoder that I used ages ago with my K2 - it still works in that I can toggle bands when I hold the F1 button. I want to use it with my remote TS-480 but the radio CAT isn't currently driving KRC2 at all and I would like some advice on how to get it working, please. Current set up: I have used the Kenwood jumper positions from the KRC2 manual and have a straight through serial cable from rig to KRC2. I am using 4800 baud (W7 and W8 in place) and the radio CAT works with my PC. The KRC2 is certainly in operate mode and I have a 13.8V PSU attached (stating the obvious!) Questions: I suspect I need to apply the handshake jumper between W14 and W17 for the TS-480? Does the position of W7 and W8 matter for 4800 baud? I'm assuming the manual is correct. Can any 480/KRC2 users comment on anything else I have missed? 73 Steve M0BPQ __ 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] K3 line in, line out transformers.
The K3 has isolation transformers for the line input (mono), and line output L and line output R (stereo). There are 3 sets of 2 transformers. In each set, the circuit diagrams shows the transformers in parallel with opposed phase. Please see the K3 Circuit diagram KIO3 Main Sheet 2, top left quadrant. one of each pair is labeled TTC-108 600 ohm line transformer 1.5 KV isolation, the other of each pair is labeled LM-NP-1001 600 ohm line transformer, 6.5 KV isolation.

Re: [Elecraft] IF out to kx3 as panadapter for K3
The transverter IF out from the K3 is a transmit signal. If you connected KX3 to the K3 transverter output then the K3 would be transmitting into the KX3. I wouldn't do that. If you connected the KX3 to the K3 IF output the KX3 would be transmitting into the K3 IF output. I wouldn't do that. You would probably need an attenuator to reduce the strength of the K3 IF output so that the KX3's front end didn't overload. Enough attenuation might prevent the K3 IF output from being damaged.

Re: [Elecraft] KX3 - ATU Disabled Problem
The firmware update released after the KXPA100 was released, had an error that in some cases turned PA MODE on even if there was no amp connected. This automatically sets the KX3 ATU to not installed. Go into the the KX3 menu to PA MODE if it is set to on, just change it to off and you will be back to normal. -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-ATU-Disabled-Problem-tp7586823p7586833.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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KX3 - ATU Disabled Problem
Since your saved configuration did not work, that configuration may have an error. Doing an EEINIT without going through the entire calibration procedure is bound to produce multiple errors of unknown types. If your KX3 is a factory built unit, Elecraft may be able to retrieve the factory configuration file for you. Contact kx3supp...@elecraft.com to see if they can send you the file. You can do *all* the calibration manually. Follow the calibration procedures in the manual. 73, Don W3FPR On 4/8/2014 2:56 AM, VaibhaV Sharma wrote: On Apr 7, 2014, at 11:40 PM, VaibhaV Sharma wrote: Hello, Just a few minutes ago, my KX3 started showing the ATU as “not inst” in the "ATU.x MD” menu.

Re: [Elecraft] K3 line in, line out transformers.
Larry, Note that there are only 3 transformers physically on the KIO3 board (not 6). So only one is used of each pair shown on the schematic. Note that one set is labeled as "ALT" meaning alternative. For that application, the phase is not critical, except that the stereo channels must match. Why it is represented that way on the schematic, only the designer can answer. I am certain it has something to do with the schematic to board layout program that was used. 73, Don W3FPR On 4/8/2014 8:51 AM, Larry Lopez wrote: The K3 has isolation transformers for the line input (mono), and line output L and line output R (stereo).

Re: [Elecraft] KRC2 and TS480

Re: [Elecraft] IF out to kx3 as panadapter for K3
Larry is correct that the Transverter "OUT" is a transmit signal. It is present when the transverter band has been set up in the menu, and the frequency is determined by the menu settings. I suspect the original poster was thinking of the "IF OUT" - which has nothing to do with Transverters - it is simply the IF output if the K3, and can be connected to any receiver or panadapter that can be tuned to the 8.215 MHz IF of the K3. The P3 is one example. 73, Don W3FPR On 4/8/2014 9:38 AM, Larry Lopez wrote: The transverter IF out from the K3 is a transmit signal.

Re: [Elecraft] KX3-2M module?
Dave, My interest in the KX3-2M has almost entirely gone after this news about the frequency stability, and there is no way to lock it to another high stability standard. I have already completed the extended VFO temperature compensation procedure. I suspect that I will either rebuild my own 28 to 144 MHz transverter which was stable enough or purchase a more modern high performance transverter such as the HA1YA unit for driving my SSPA for 144 MHz EME and terrestrial DX, which only needs a few watts of drive.

Re: [Elecraft] Line Out Jack
I'm curious about this. If anyone has reference to an actual 1/8" connector, please forward off list. I don't recall them ever being anything but 3.5mm. 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. They are called out either as 6.35mm or 6.3mm, which is quite accurate because they originated as the fractional inch dimension. 73, Josh W6XU On 4/7/2014 7:11 PM, Don Wilhelm wrote: 3.5mm and 1/8 inch are now the same thing - one place calls them 3.5mm while others use the 1/8 inch designation for the same thing.

The big issue now is manufacturing tolerances that might mean some jack and plug combinations are tight while other combinations may appear to be sloppy. 1/4 inch plugs and jacks are more tolerant of sloppy tolerances i.e +/- 0.01 mm compared to 3.5mm is much greater than +/- 0.01 mm compared to 7 mm (or is it 8mm?). __ 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] K3 line in, line out transformers.
These transformers don't have an industry standard form factor and pinout. Therefore it is standard practice to place pads on the PCB which mate parts from multiple suppliers. It's smart engineering to avoid being locked into sole sourced components. Those transformers called out are made by Tamura and Shinholm (marketed by Bourns). Both make high quality transformers. 73, Josh W6XU On 4/8/2014 8:51 AM, Larry Lopez wrote: The K3 has isolation transformers for the line input (mono), and line output L and line output R (stereo).

Re: [Elecraft] The Final Build and order for K3
Hi Jim, I fully understand what you are saying, and agree with you, however my eyesight is not at all what it used to be, so I elected to have them built if for me. It feels wrong, and I really did want to build one, but, the last kit, was such a pain to build compared to how they used to be, I have all but given up on kits. I used to build all the time, PC boards, some Heathkits, etc., but my neck was so stiff after the last build-- from keeping my head tilted up to see through the bottom lens of my bifocals I can't imagine three days of that... I feel like I am cheating to not build it, because I want to see the insides, and get the fun of putting it together, but no more for me I fear.

Is it still planned for high enough stability for JT65B mode and a maximum power of 10w? Hi Lance, I'm not sure where you got that figure. Our postings on this topic are summarized in an FAQ (http://www.elecraft.com/manual/KX3-2M%20FAQ.htm). - Max power is 3 W. - The module is unlikely to support very narrowband modes, because short-term local oscillator excursions at the I.F. (48 MHz) are, in effect, multiplied by about 3. FM and AM modes can be used with normal factory temperature compensation on 2 m. To use CW/SSB, the extended VFO temperature compensation procedure will be required. This level of compensation would also allow the use of narrow-shift RTTY. But JT65 and similar modes on 2 meters would probably require tighter frequency stability. 73, Wayne N6KR I am somewhat curious about the pessimism here. Surely the important characteristic is the short-term stability over the one to three minute time frame, and most of that is going to come from thermal. So if the base oscillator is +/- 1ppm over 0-50 (from the manual and about the TCXO midpoint) this is 150Hz at 2m. A 10Hz drift which is the FAQ number would require a temperature change of the oscillator module of about three degrees, or about a degree per minute. That seem quite a lot to me, particularly if you are applying s/w correction to help the TCXO.

Re: [Elecraft] P3/K3 spurry
I had problems similar to what you describe when I first got the P3. The story is simple: Use a mil-spec RF patch cable between the K3 and the P3. The long story: I tried grounding straps, redoing the station ground system, checking all antenna connections, was sent a couple of replacement cables - and in general wasted a lot of time over a period of a couple of weeks trying to rid my P3 of the odd signals it was displaying. Each replacement cable did improve or change the display. This clued me in that the cable had a direct effect - so I put on my own mil-spec cable - and immediately the P3 was fixed and remains to today. Try replacing the cable with a known quality cable and see if that fixes your problem - before you jump through any additional hoops. Let me know if it does - I would be interested if my solution helps anyone. Use a mil-spec cable if possible - not something of unknown quality.

Hi Ted, I don't have split screen but I do have my external monitor running dual purposes. Most LCD monitors have double or triple inputs these days. And many PCs have 2 or more video outputs. You hook up the P3 SVGA card to the VGA input of the monitor and you hook up the DVI monitor input to the DVI output from your PC. (Your primary PC monitor would run off of the VGA output of your PC). My monitor has a button on the front that allows it to be quickly switched between the VGA (P3) and the DVI (PC) inputs. You would want to avoid a monitor that does not have a dedicated button.

Re: [Elecraft] KX3-2M module?
Yes, and No, to be unhelpfully exact... My TS2000X is "off" by about 1.7kHz compared to other peoples 'dial' settings on 1296MHz. I know this and I compensate, but the higher up the chain you go, the worse the problem gets... Since I have another radio to "do" 2M on (TS2000X) I'm only looking to use the KX3-2M for two things. 1. The occasional use in the field, or from a hotel room (though not so much that to be honest) where I agree, I can probably compensate manually, as long as it doesn't drift too far, too fast but the other reason may be a game killer, as far as I'm concerned. and 2. As the IF for a 24GHz narrowband transverter.

Re: [Elecraft] KX3-2M module?
Dave, I do not understand how "a few Hz on 2M equates to a heck of a lot of kHz on 24GHz" A transverter is *not* a multiplier (it is a mixer). A frequency shift at the input should produce an equal frequency shift at the output, so any drift due to the 2 meter source should produce the same amount of drift at the 24 GHz output. i.e. 10 Hz drift in the KX3 output would produce 10 Hz drift in the transverter output no matter what the output frequency may be. Yes, there may be additional drift from the Local Oscillator in the transverter, but that is a different story (there are likely frequency multipliers in the LO chain). So unless what you are referring to is something different than a normal transverter, I do not understand your statement. Multiplying the signal rather than mixing it with a LO will destroy any modulation, so you would be slaved to CW. 73, Don W3FPR On 4/8/2014 4:29 PM, Dave wrote: and 2.

Phase noise is quite low on 2 meters, since the LO for 2 meters is derived directly from the HF-6 meter synthesizer. We'll post measurements on this soon. The 2-meter module can be used on CW, SSB, and some data modes once the temperature compensation is applied.

[Elecraft] KX3-2M module will work well for CW and SSB, even as an I.F. for higher-band XVTRs
There seems to be some confusion on this point. Once a KX3 has had the extended temperature compensation procedure applied, it will have drift of only about +/- 10 Hz in CW and SSB modes on 2 meters. This is not as good as an oven-controlled oscillator (which there isn't room for, of course), but it should be quite satisfactory for SSB and CW use. If you use higher-band transverters after the KX3, using 2 meters as an I.F., any drift in external units will add/subtract to the total, not multiply the 2-m drift upwards. (Unless you're using a frequency multiplier -- that's a different story.) 73, Wayne N6KR __ 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] KX3-2M module?
Dave, The drift at a *transceiver* input is *not* multiplied by a transverter. A transverter is a linear device. Any change in the input frequency results in an equal change in the output frequency. In other words, if you move your 144 MHz frequency (with the VFO) by 12 kHz, how much does the 24GHz frequency change? If you are using a transverter, it should also change by 12 kHz. The same goes with drift at the 144 MHz input. If the 144 MHz signal changes by 10 Hz, the change in the transverter output should also be 10 Hz. I would expect the greatest contribution to drift at 24 MHz would come from drift in the transverter Local Oscillator, not from drift in the driving transceiver. Yes, if you have an intermediate transverter between (say 144 to 1.2 GHz) between your KX3 and the final transverter to 24 GHz, that transverter's LO drift will be added, but that is due to the LO drift in that intermediate transverter, not from drift in the KX3. The drift is *not* multiplied if you are using proper transverters. If you are using multipliers instead of transverters, I concede, but than only CW mode is possible because any modulation on the signal (voice modes) would be so corrupted that reception that demodulation would be unpredictable and result in garbage unless one knew the exact multiplication scheme of the transmitting station. I don't think anyone does that anymore. Now, if your SHF "transverter" is such that a 12 kHz change in VFO frequency at the input results in a much greater change in the output frequency, you have something quite different than a transverter. 73, Don W3FPR On 4/8/2014 6:18 PM, Dave wrote: - Original Message - From: "Bob" To: "Dave" ; Sent: Tuesday, April 08, 2014 9:55 PM Subject: Re: [Elecraft] KX3-2M module?

Re: [Elecraft] KX3-2M module?
Hi Dave, for me the most important reason to buy the KX3 was the 2 m option, too. If Wayne says the frequency will be stable +/- 3 Hz I think nobody will hear that in CW/SSB, you will not even recognize, be it in a contest or while working D4 on double hop ES on 2 m. ;-) Likewise with "normal" transverter use on 10 GHz which we plan to do, too (if the LO is stable enough ... you know there are 2 factors influencing things: freq stability of the KX3 itself which the temp correction takes care of *and* LO stability in the KX3-2M transverter itself). JT65 could be a different matter if the frequency will be corrected every second or such. Even then it might be good enough. +/- 3 Hz is well within the tolerance of JT65. What might be a problem is that JT65's tolerance is for drifting signals, not "jumping" signals. So we will have to see how that works. For comparison the frequency stabilization of the K3+K144XV with the K144RFLK is using a comparable method and I do not have problems on JT65b. But "comparable" is not "similar", of course, i.e. no temp curve correction from memory but a real reference lock. Nevertheless the final effect seems to be the same for me. Maybe Wayne can shine in on that point again. 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 08.04.2014 23:58, schrieb Dave: - Original Message - Sent: Tuesday, April 08, 2014 9:39 PM Subject: Re: [Elecraft] KX3-2M module?

[Elecraft] K2 drifting issue

I've done this and CAL PLL a few times over the last 10 years, I guess ref osc just doesn't like 4000kc I built the K2 kit in 2001 and the rig has seen spotty usage until recently (I retired) and gets daily use.

Re: [Elecraft] P3/K3 spurry
Somewhere, not too far after the introduction of the P3, Elecraft seems to have received some inferior RG-58 patch cables with BNC connectors from a supplier and the problems were several. In my case, at narrow spans [20 KHz or so], the baseline would just drift up. Putting my hand on top of the P3 sent it back down where it belonged. At wider spanss [~100 KHz, I could see that it looked like a very broad spur of variable amplitude. Elecraft sent me a new cable with explicit instructions to cut the old one into small pieces so it didn't show up at a flea market. :-) I did, the new cable solved the problem. Anyone who has worked in manufacturing engineering knows the problem, sometimes it's 2nd or 3rd generation ... your supplier got some bad stuff from their supplier and didn't know about it. It is very important that the case of the P3 be electrically intact ... any overspray on contact surfaces be removed and *all* screws tight. Also, if you have an early K3 [mine is #642], there is a simple mod to increase the first IF output. Just destroy one SMT resistor ... you don't have to unsolder it, just break it with needle nose pliers ... and replace it with a "regular" resistor. Results in less gain requirement in the P3, and got rid of a lot of "grass" for me. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 4/8/2014 11:09 AM, Bill W2BLC wrote: I had problems similar to what you describe when I first got the P3.

[Elecraft] 24 hour Reminder -- Own a Z90 Panadapter and Help a Museum
Just a reminder - there's less than 24 hours to make your offer for the Z90 panadapter. Proceeds to charity.

This Z90 was owned by a customer who is, for medical reasons, no longer able to enjoy ham radio and has asked me to see if it can be put to good use. For those not familiar with the Z90, it's the first product of Clifton Laboratories and is a microprocessor controlled digital panadapter. I believe it was the first digital panadapter kit aimed at the ham radio market. It was the cover story in the March/April 2007 QEX, with part two published in the May/June 2007 QEX. You can learn more than you ever wanted to know about the Z90 at http://www.cliftonlaboratories.com/Z90.htm and if that's not enough detail, additional links can be found at http://www.cliftonlaboratories.com/prior_products_-_no_longer_available.htm The Z90 was produced in one run only, 50 units split between the Z90 with LCD display and the Z91 computer interface model. The Z90 was designed with K2 owners in mind, but it's a general purpose digital panadapter suitable for IF frequencies from 455 KHz to above 60 MHz, although performance drops off above 60 MHz. It works with the K3, but the Z90 does not have the integration bells and whistles for tuning, etc. that later panadapters have. In 2007, a new assembled Z90 with running spares sold for about $700. With the consent of the original owner (and thanks to the permission of Eric and Wayne to post this information on the Elecraft reflector) the proceeds from the sale will go to a local charity, the Lee Fendall House in Alexandria VA. www.leefendallhouse.org Here's the fine print ... 1) The purchaser will make payment directly to the Lee Fendall House and when the payment is received, I'll ship the Z90 and accessories to the purchaser. 2) Although the Lee Fendall House is a non-profit charity, my understanding of the tax code is that donations are deductible for tax purposes only to the extent they exceed the fair market value of "premiums" received. In this case, I believe the fair market value of the Z90 will be whatever the sale brings, so the purchase price will not be deductible as a charitable contribution. You may wish to consult with your tax adviser, of course. 3) I will include - no extra charge - a Z1B buffer amplifier (either kit or assembled) if the purchaser needs that to connect the Z90 to a particular receiver. If the purchaser will use it with a K2, I'll include the Z1B-K2 version of the buffer amplifier. If the Z90 is to be used with a K2, I will also provide a bandpass filter designed to go between the Z1 buffer amplifier output and the Z90 input. 4) In order to maximize the amount the Lee Fendall House will receive, the sale will be to the person offering the highest bid.

Re: [Elecraft] KX3-2M module?
The K144XV's REF LOCK option uses phase-locking (via a PLL IC) to the 49.380-MHz reference (TXCO). This is extremely stable. The KX3-2M module, when used with the KX3's extended temperature compensation, uses frequency locking (via firmware and a temp-sense IC). So it will "jump" in small increments, typically +/- 3 Hz. This may not be compatible with JT65, though I haven't tried it myself.

Re: [Elecraft] K2 drifting issue
Eddy, The K2 dial calibration does *not* depend on the 4 MHz reference oscillator, except at the time CAL PLL and CAL FIL is done. The data from CAL PLL and CAL FIL is stored in EEPROM and will not change unless those routines are done again. In other words, once CAL PLL and CAL FIL are finished, the 4 MHz reference can drift all it wants to without altering the dial calibration of the K2. Other than for the duration of CAL PLL and CAL FIL, that 4 MHz oscillator only serves as a clock for the MCU and for that purpose, it can have considerable drift without causing any problem. How much is the dial calibration off? If it is less than 20 Hz, that is the limit of the DAC used in the K2, and there is little that can be done about that (unless you want to redesign it). If you are experiencing drift of your K2, you might want to look at the thermistor mod instructions for modifying the value of RA on the thermistor board. If your K2 does not have the thermistor board installed, then you should order E850138 and install it. If you do not have the BFO L33 that has many turns and is secured by a high value 1/8 watt resistor, you should order and install the BFOMDKT. If both of those are installed in your K2, you can change the compensation for the PLL by modifying the value of RA on the thermistor board. See the instructions on page 4 of http://www.elecraft.com/manual/PLL%20upgrade%20rev%20C.pdf. Take heed about giving your K2 sufficient time to warm up to temperature before running CAL PLL and CAL FIL. The spec is for 5 minutes after power on at 25 degC (which is 2 degrees higher than normal room temperature). 73, Don W3FPR On 4/8/2014 6:49 PM, Eddy wrote: With the expert help from Gary and Don, I believe I've finally gotten the K2 SSB audio to sound pretty damn good on both LSB and USB.

Re: [Elecraft] KX3-2M module will work well for CW and SSB, even as an I.F. for higher-band XVTRs
So why did a previous reply suggest that it would not be OK for narrowband use? Anyone who uses a transverter will know that, as the frequency of the lower frequency used and the transverter frequency used changes then the output/input of the chain will change. The multiplication occurs as the chain of frequencies up to where you want to get to multiplies and I really do not expect to have to argue this with RF engineers...

Once a KX3 has had the extended temperature compensation procedure applied, it will have drift of only about +/- 10 Hz in CW and SSB modes on 2 meters. This is not as good as an oven-controlled oscillator (which there isn't room for, of course), but it should be quite satisfactory for SSB and CW use. If you use higher-band transverters after the KX3, using 2 meters as an I.F., any drift in external units will add/subtract to the total, not multiply the 2-m drift upwards.

Re: [Elecraft] KX3-2M module will work well for CW and SSB, even as an I.F. for higher-band XVTRs
Dave, Are you using a frequency multiplier *applied to the I.F. signal*? If not, then any drift at the I.F., which in the KX3-2M case will be +/- 10 Hz, will simply be *added* to any drift in the final signal. What I said was that this amount of drift might not be compatible with narrowband data modes. This would also apply to modes like WSPR, unless there's AFC in the algorithm that's tolerant of minor frequency shift. I haven't tried WSPR myself.

That is, indeed, pretty much the standard way nowadays. In a transverter, the transceiver input and output are MIXED, not multiplied. So the total frequency drift is the SUM of the drift of the transceiver (in this case, the KX3 with 2M transverter) and the drift of the UHF transverter. Drift of the KX3 with 2M transverter would be multiplied ONLY if you were to use a system that multiplied the TX output to feed the 1.2 GHz transmitter. That's feasible, I guess -- 1296 is the 9th harmonic of 144 MHz -- but the 2M rig would need to TX below 144 MHz to cover all of the band, and the RX would still be MIXED. 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

Erm, yes, and yes. I think that you need to think about what I said that I wanted to use the KX3-2M for before you try to reply to my complaints that it wont do what I want it to do.

Re: [Elecraft] KX3-2M module will work well for CW and SSB, even as an I.F. for higher-band XVTRs
If you're using a multiplier of the I.F., then yes, you will need better stability than we can provide within the constraints of the KX3's hardware. I'll add this to the FAQ for the 2-meter module. If on the other hand you're using mixing to get from 2 meters to the higher bands, the KX3-2M will work just fine for you in CW mode. 73, Wayne N6KR On Apr 8, 2014, at 4:48 PM, "Dave" wrote: > Erm, yes, and yes. > > I think that you need to think about what I said that I wanted to use the > KX3-2M for before you try to reply to my complaints that it wont do what I > want it to do. > > I'm not using WSPR or any other data modes, other than CW, and that seems to > be where we are getting confused... > > Dave (G0DJA) > > Dave (G0DJA) > - Original Message - From: "Wayne Burdick" > To: "Dave" > Cc: ; "Elecraft Reflector" > Sent: Tuesday, April 08, 2014 11:28 PM > Subject: Re: [Elecraft] KX3-2M module will work well for CW and SSB,even as > an I.F. for higher-band XVTRs > > > Dave, > > Are you using a frequency multiplier *applied to the I.F. signal*?

Re: [Elecraft] KX3-2M module?
The specs for frequency stability are not good enough for the JT65 modes (+/- 1 ppm typical over 0-50 C). On 2m, that would be +/- 144Hz. The extended temperature compensation improves that, but it will never be as stable as a K3 with an external reference. Did you expect it to perform much, much better than the specs?

Re: [Elecraft] KX3-2M module?
Actually, with extended temp compensation applied, the KX3-2M module's long-term frequency stability is typically better than +/- 0.1 ppm (+/- 10 Hz). 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 On Apr 8, 2014, at 5:02 PM, Walter Underwood wrote: > The specs for frequency stability are not good enough for the JT65 modes (+/- > 1 ppm typical over 0-50 C).

Re: [Elecraft] KX3-2M module?
Am I reading something wrong? You say that you would need +/- 144 Hz, and Wayne is saying that you can get +/- 10 Hz with the extended temperature compensation. That seems that it would be good enough. I'm also seeing all this complaining about stability, and the only counter example appears to be +/- 1700 Hz at 1296Mhz for a TS2000, which doesn't strike me as all that good either. Is the real issue that there is no support for an external reference?

Re: [Elecraft] KX3-2M module?
Frequency drift +/- 10-Hz at 144-MHz may be fine for running digital-mode eme. I typically think of keeping drift <20-Hz as a requirement. It will depend on how rapid the frequency changes and how big the steps. JT65 is fairly adaptable to some drift. When I am in the "heat" of an eme contest with 5-7 stations calling me simultaneously on or near the same frequency (within 100-Hz) I select 20-Hz DSP bw to exclude another station capturing the decoder. I have worked stations that have drifted 30 to 50-Hz through the course of a contact by merely reseting the center frequency to follow the change at discreet times. If drift is faster than 50-seconds then it becomes a problem since one does not want a frequency change during a given sequence period (Nom. 1-minute). I have discussed a few "fixes" off list with David Anderson if it turns out one is needed. **This is only important to the eme'r or mw operator so will not affect the majority of users.** On mw the frequency stability of the IF radio (KX3) is added to the stability of the transverter since they mix signals. Many use PLL's for the mw transverter; for example on 10-GHz the frequency is held to 9x the synth frequency and resulting error is probably not more than 9-Hz and more likely half that. +/- 19-Hz frequency uncertainty on mw is actually very good. Might be a problem for mw eme'rs so the KX3 might not be the radio to use. EME Dxpeditions commonly do not operate above 2.3 GHz (LOx2) so the requirements are not as tough. Far more common is 50, 144, 432, and 1296 MHz eme dxpeditions (which makes KX3 very handy due to size...same issues as with portable IOTA, SOTA type operations). So we will find out when I have one to test! 73, Ed - KL7UW From: Wayne Burdick To: g...@keskydee.com Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] KX3-2M module?

[Elecraft] Strange RFI question
Hello everyone! I'm not sure if this is the correct forum for this sort of a question but i figured i'd give it a shot. I've been going out of my mind with this strange signal pattern i've been seeing on my new panadapter connected to my new K3. I first saw it on 20 meters. It seems to be the same signal pattern, spaced evenly, at 61 kHz intervals. Something tells me that it could very well be outside of my shack. I've got the street power lines 15 feet in front of my house, with a big transformer on top of a pole. I just took a video of the whole thing and you can also hear the sound of it, especially while i tune it up and down. Here's a link to the video file in my DropBox: https://dl.dropboxusercontent.com/u/111549/rfi/strange_rfi.wmv Sorry for the format. This screen capture program only does Windows Media Video. I've gone to a point where i've disconnected everything in the shack. Literally. And i could still hear it. My Yaesu 857D also hears it, with the same antenna hooked up to it, so that tells me its not my K3 or the panadapter (for that matter). I also tried hooking up another antenna (i have a home made fan dipole) and i can still hear it. So its not the antenna (right?). I'm very open to any suggestions as to what to do? How to narrow it down? Thanks a bunch in advance! Slava, W2RMS P.S.

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.

Re: [Elecraft] Strange RFI question
Slava, I can't make the link work but regularly spaced signals are a classic sign of a Switched Mode Power Supply [SMPS]. I host the local wireless company's RAP for our neighborhood on my tower, in return we get the backhaul speed [17 Mbps] for free ... yes, we power it. Really great for Andrea's Netflix addiction. They recently replaced the gear, and it is now powered by a UPS in our shed with an SMPS with raucous noise peaks every 26 KHz +/-, they move around a bit. Since the wireless company seems to be preoccupied with getting new customers, I'm going to wind a couple of toroid chokes and see if I can fix this. Wall warts are in most cases these days SMPS. So are LED lamp power supplies. I'll send you a screen shot of mine if you'd like, their UPS is connected to a cable to the top of the tower and down to the router at the bottom ... resembles a 160 Inv-L. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 4/8/2014 6:34 PM, Slava Baytalskiy wrote: Hello everyone!

I believe you have identified an HRD problem. When the KXPA100 is enabled, the KX3 ATU is disabled.

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.
