Both > stations have access to broadband, but what speed will give satisfactory > results? My experience operating remote is with a K3I/O-mini and Remote Rig interfaces. My station is 1,250 miles from where I?m currently located. The K3 transmitter site (Southeast Georgia) is in a rural setting that uses DSL with a downlink capability of about 20 Mbps and uplink capability of about 1 Mbps (the fastest speed available for residential customers). The control location (Boston) with the K3/IO-Mini uses Comcast/Xfinity which provides a downlink capability of 90 MBps and 6 Mbps uplink. With this setup I have no problems using the K3/IO through the K3/IO-Mini with excellent audio and instantaneous management of the radio. At the same, I?m using web-based interfaces (RR-1216H) to control the KPA500 amplifier and Green Heron RT-21 rotor controller. One of the advantages of Remote Rig is that there are various audio codec options available which can be set depending upon how much bandwidth is available. My remote rig setup uses a relatively low audio setting (16 KHz) but the audio sounds fine to my ears and I have no problem with this setup. I haven?t experimented with higher audio settings in part because I have other devices feeding data through that 1 MB Uplink as well. Bottom line is that if you have true ?broadband? at both locations, I wouldn?t expect any problems.

We use Teamviewer to view and control the station automation, it seems to consume around 300 Kbps under most conditions.? The RRC CODEC has a variety of options, some requiring more BW than others. Web cams on the monitor can really increase the BW requirement. They usually work in a differential mode, sending only the changes from the last frame.? A tree outside the window in a little breeze will make a huge number of pixel changes in the shack lighting and the camera really sucks up the BW. Packet-level reliability is far more important than raw speed.? If there are other devices on your sub-net with high throughput, or if your WAN is unreliable at packet-level, it may be impossible to operate. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/1/2018 12:38 PM, David Cutter via Elecraft wrote: > I will soon be building a remote control station about 20miles away.

The diameter of the hole on my Front Panel was 10 mm as measured with my calipers. The diameter of the threaded mount on the encoder is ~ 9 mm while the diameter of the ring at the base of the threaded mount is ~ 10 mm. How is the encoder correctly mounted by hardware to the inside face of the Front Panel? I tried 3 methods without success. 1) First was to just add the washer and nut to the shaft and try and tighten it down with a wrench, but the encoder kept tilting. 2) So, I thought perhaps the inner diameter of the hole in the Front Panel was too narrow because of paint thickness. I scrapped off the paint from the inside of the hole and a bit of aluminum, then the 10 mm ring at the base of the encoder shaft fit in the hole nicely. I could then barely tighten down the shaft with the nut and washer because this ring at the base of the encoder is slightly thicker than the thickness of the front pannel. When I put on the large knob, 2 felt washers were not thick enough to provide resistance to knob turning, so I thought I made a mistake in enlarging the hole. However, the position of the PC board on the back of the encoder was close enough to the Front Panel to allow the attachment of the Control board to the 1/2' posts attached to the back of the Front Panel Board. 3) To solve the felt thickness problem, I put a very thin (0.2-0.3 mm) washer, ~9mm ID, on the threaded shaft of the encoder before inserting it into the hole in the Front Panel to stabilize the tilting problem. I attached the washer and nut to the threaded shaft and now the double felt washers work as described to provide friction against the inner surface of the large knob. However, now the PC board on the back of the encoder extends too far away from the the back of the Front Panel Board to allow attachment of the Control Board to the two posts. So, how to solve this problem?

The best solution is to purchase new Front Panel metalwork. Enlarge the hole for the threaded part of the encoder just a bit. I use a thin knife blade and 3 or 4 passes with it inside the encoder hole will do the job nicely. The other way (not as nice) is to take the encoder to a nearby hardware store and find a washer that has a hole large enough to pass the ring at the base of the threaded portion of the shaft, and use that as a spacer behind the front panel metal. In either case, you will have to tighten the lockwasher and nut enough so the encoder will not twist on the front panel. You must have 3 felt washers under the knob. Two were packed with your encoder assembly and a 3rd one was packed with the Front Panel parts bag. Flush trim (diagonal cutters are not good enough) the leads on both the encoder board and also the back of the control board in the area which might contact the encoder board. The two rubber pads must be placed at the top of the front panel board (on the solder side). If the encoder board can still contact the control board, cut a piece of card stock (a piece of a QSL card will do) and place it between the encoder board and the control panel. 73, Don W3FPR On 9/2/2018 7:30 AM, Ted Salmon wrote: > The encoder plus attached PC board is attached to the Front Panel with a lock > washer and 1/2" hex nut on the encoder shaft.

Any ferrite core will have an FTxxx diameter designation with two digits after the hyphen. That W3EDP antenna is a strong suspect, as is any off-center fed antenna or end fed antenna. They can produce large amounts of RF in the shack. Install a GOOD current mode choke near the antenna feedpoint. One of the best is a stack of 4 or 5 FT240-31 with the coax wound for 4 or 5 turns through the center. That should be placed close to the antenna end of the coax - exception, an end-fed antenna may need to use a part of the coax as a counterpoise (which is why a minimum length of coax is specified for them) - put the choke that minimum length away from the antenna. 73, Don W3FPR On 9/1/2018 11:00 PM, Gwen Patton wrote: > This happens very rarely for me EXCEPT for 30 meters.

Apart from use with satellite-based services (e.g., Hughes, maritime VSAT, etc.), I've found latency is reasonably low even from hotel and 4G connections. Jitter will almost always be the dominating factor, especially when using a remote CW connection. I won't even try satellite remoting; it's a horrible experience. From home or when roaming on my iPhone 's WiFi hotspot connection, my QSK CW experience is almost as good as a local connection. The remote site is on Verizon 4G/LTE service with a 30 GB/month plan. I use PingPlotter software that shows typical ping time under 50 ms. from home to my remote site about 30 miles away. The longest measured latency is the link between the Verizon cell site and the 4G router at the shack. That comprises about 50% of the total latency. In between, the service changes hands among several internet transport providers. I just ran a quick test and see 12 hops before it gets to the destination. The path changes from day-to-day. Back to the OP's question of "what speed will give satisfactory results?" Assuming a K3 with RemoteRig, look at the RemoteRig manual, Appendix A for a table that illustrates data consumption as a function of bit rate and whether dual-channel audio is engaged. For example, 12-bit linear, 2 channel audio (for dual receive) requires 240 kbps. That's not much data. Of course, there's going to be other overhead when running applications on the same link. Any of the high speed "light" packages will work fine with the RemoteRig unless using high bit-rate settings. I've noticed no operating issues when using an account with 1.5 Mbps download and 500 kbps upload speeds and when either VNC or TeamViewer is running in the background. My iPhone's WiFi hotspot typically gives 10/5 Mbps service as long as there's ample 4G/LTE signal strength.

They can produce large amounts of RF in the shack. Hi Gwen, Don is correct. The W3EDP with a large choke Balun, as pictured, between the Unun and KX3 is an OCF Doublet with a resonant frequency of 11 MHz. It is rather difficult, if not impossible, to isolate a dipole end impedance using a choke Balun. The KX3, being at the high impedance point on 30 meters, will experience a rather high RF voltage. A way to determine if the rig is part of the antenna is to use what I call a "touch test." Observe SWR while transmitting, if touching the KX3 antenna BNC jack causes the SWR to change, then the KX3 is part of the antenna. At the extreme, the touch results with a RF burn. I have experience RF burn at 15 watts.

So figure what you paid for the K3 and whatever options/upgrades you bought and go from there. If you are willing to offer the buyer a short term money back guarantee, that will give you a leg-up on a higher price. Consider that the buyer will be buying it as an unknown and may want to send it in for a general checkup and any possible upgrades, so that will affect your asking price by about $250. 73, Don W3FPR On 9/2/2018 10:53 AM, Mike Greenway K4PI wrote: > I have a K3 I am planning on selling to a local here but want to get > some input as to a fair price.?

To confirm, is your SWR 3.0:1 or 2.0:1?? According to the KAT500 manual (page 21) you can use the KAT500 Utility Program to set VSWR thresholds for keying an amplifier, ?Also, you can set an SWR threshold at which the key line will not close to enable the external amplifier to protect it from excessive SWR.? These thresholds can be set for all bands or individual bands. This would presumably work with bypass mode as bypass is defined as bypassing the tuning elements in the tuner?s matching network while the tuner?s SWR meter continues to function and the antenna selector will still switch to the antenna chosen for a particular band. I haven?t made adjustments using the Utility Program so I cannot speak from personal experience nor do I know what the default values are for VSWR threshold as I?m not currently where my ham station is to confirm. You will need to experiment carefully to ensure that you get the intended results. Also keep in mind that the KPA500 protects itself. See page 19 of the KPA500 manual (?Fault Conditions?) which discusses SWR measurements by the KPA500 itself where ?minor faults? in VSWR will result in a 3 dB reduction in output (?Attenuator Faults?) and continues to operate (if the SWR improves the attenuator is removed). In the case of severe SWR problems the amplifier goes into standby (?Hard Faults?). Hard faults require intervention by the operator to place the amplifier in ?operate? presuming that the cause of the excessive SWR has been resolved. The more basic question is what SWR levels the KPA500 will operate. According to the KPA500 manual (page 17) the amplifier is designed for 1.5:1 or less (the amplifier SWR LEDs are green). Between 1.5 and 2.1 the LEDs are yellow, and above 2.1 the LEDs are red. I could not find a reference in the manual that defines at what SWR level an ?attenuator fault? or a ?hard fault? due to high SWR are generated, but this suggests that an attenuator fault presumably happens when SWR is above 2.1 which is why I?m wondering if there?s a typo in your first sentence regarding current SWR. The KAT500 manual (page 21) also notes, ?The Elecraft KPA500 amplifier also works efficiently into a load SWR of 1.5:1. Suggested values are 1.8:1 to launch an automatic tuning operation and 1.2:1 for bypass.?

The nut and washer go on the "outside", that is, the front facing side of the front panel behind the main VFO knob. The encoder shaft has to be fully seated on the inside of the front panel with the encoder shaft extending a good distance out, then tighten the nut and washer on the outside of the front panel. To my knowledge there should be nothing on the encoder shaft on the inside of the front panel. My encoder shaft appeared to be too large for the hole, and I was about to "clean" the hole when I gave it one last push and it popped in. Very tight fit but the encoder shaft base was flush on the inside of the front panel. After the lock washer, nut, 3 felt washers and the Main VFO knob were installed on the shaft, the backside of the main VFO knob was parallel to the front panel with nice friction. 2. My kit came with 3 felt washers and I had to use all three to get the right friction that is close to that of my K3. Look in one of the other envelopes there should be another felt washer. IIRC, it was in one of the misc envelopes and not in the Main VFO board assembly bag with the other two washers. 3. My Main VFO board assembly bag came with a 4 pin male header that actually fit the holes in BOTH the encoder PCB and the Front Panel Board. If that male header is installed you may have found the problem as the directions for installation say to use stripped wire. I asked Don about the extra 4 pin male header in my bag and he said follow the wire directions. 4. The bottom side of the encoder PCB will have to have ALL the joints cut as flush as possible because when the Control Board is installed, there is very very little room between the two PCBs. The Main VFO board assembly instructions say you can you use thin paper as an insulator between the two boards. That's about all I know. If I have any of that wrong I'm sure Don will chime in soon and correct me. I'm still working on K2 #7815, just a bit further along than you. Good Luck.

In the case of a 1.5:1 SWR, the load Z is 75 ohms, with a power of 500 watts the line current is 2.58 amps with a voltage of 193.6 volts. At the same time a 1.5:1 SWR, the load Z is 33.3 ohms, at 500 watts the line current is 3.87 amps and with a voltage of 129 volts. Both 75 ohms and 33.3 ohms represent a 1.5:1 SWR with reference to a 50 ohm source. The points being related to the circuit designs, how much current or how much voltage exceeds the component ratings???? Hence we see manufacturers specifying maximum SWR values.???

My question was naive in only asking for speed. Several have pointed out that latency is probably more important because the speed is easy to attain. I need to translate this to the characteristics that the providers use, eg ping, which I know little about. From advice I have received here and elsewhere it looks like I will be safe to continue with the project and to concentrate on achieving the lowest latency at each end - for that I will call upon further advice. 73 David G3UNA -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Paul Christensen Sent: 02 September 2018 14:01 To: elecraft at mailman.qth.net Subject: [Elecraft] internet speed for remote K3S >"My experience is exactly that; look out for latency; that is the killer." Apart from use with satellite-based services (e.g., Hughes, maritime VSAT, etc.), I've found latency is reasonably low even from hotel and 4G connections. Jitter will almost always be the dominating factor, especially when using a remote CW connection. I won't even try satellite remoting; it's a horrible experience. From home or when roaming on my iPhone 's WiFi hotspot connection, my QSK CW experience is almost as good as a local connection. The remote site is on Verizon 4G/LTE service with a 30 GB/month plan. I use PingPlotter software that shows typical ping time under 50 ms. from home to my remote site about 30 miles away. The longest measured latency is the link between the Verizon cell site and the 4G router at the shack. That comprises about 50% of the total latency. In between, the service changes hands among several internet transport providers. I just ran a quick test and see 12 hops before it gets to the destination. The path changes from day-to-day. Back to the OP's question of "what speed will give satisfactory results?" Assuming a K3 with RemoteRig, look at the RemoteRig manual, Appendix A for a table that illustrates data consumption as a function of bit rate and whether dual-channel audio is engaged. For example, 12-bit linear, 2 channel audio (for dual receive) requires 240 kbps. That's not much data. Of course, there's going to be other overhead when running applications on the same link. Any of the high speed "light" packages will work fine with the RemoteRig unless using high bit-rate settings. I've noticed no operating issues when using an account with 1.5 Mbps download and 500 kbps upload speeds and when either VNC or TeamViewer is running in the background. My iPhone's WiFi hotspot typically gives 10/5 Mbps service as long as there's ample 4G/LTE signal strength.

The current is determined by driving voltage and total (complex) series impedance. The choke RF impedance will have a reactive as well as a resistive component, and so does the circuit before the choke is applied. The reactances may be of opposite signs and cancel out, in which case adding the choke may actually make it easier for the common mode current to flow. It is easy to think that one can add a marginal choke and look for a small improvement as a reliable indication that a good choke will be worth the investment or not. Wrong! Only then the choke tried has high enough impedance to dominate the circuit can one judge whether whether adding chokes helps.

BUT the following occurs randomly (no matter band \ mode \ power) with a tendency to repeat more often, from day to day : 1. At some point in the operating cycle (minutes from "ON" - can be 3 or 43) the amp will not key when triggered by my K3. There is a "double click" sound similar to a relay bounce. Usually On the next PTT from the K3 it will key as before, and perhaps a few cycles later this might happen again. 2. Either starting the amp from cold or after some idle time the LCD characters dim, become unreadable and finally disappear. The LCD remains lit but empty. This might or might not fix itself when powering the amp off and on again. At the time of writing this post it is the steady state. 3. The keying issue in "1" above isn't necessarily linked to issue "2", but sometimes both occur at the same time. 4. So far even with empty LCD the amp is amplifying; RF & SWR LEDs indicate expected readings. Any ideas please?

If you don't invert the sidebands, the total Doppler shift is the sum of the shift on two bands. For a satellite in a standard LEO orbit with an uplink at 2 meters and downlink at 70 cm, the total Doppler shift is +/- 3.5 kHz on 2 meters and +/- 10 kHz on 70 cm. If the sidebands were not inverted, the total Doppler shift through the pass would be +/- 13.5 kHz. If you invert the sidebands, the total Doppler shift is the difference between the shift on two bands, or +/- 6.5 kHz. That's far easier to deal with if you're compensating for the Doppler shift manually. 73, Paul, N8HM On Mon, Sep 3, 2018 at 9:13 AM Jim Rogers wrote: > > A common LO (local Oscillator) for the receiver and the transmitter is > the only reason I can think of. > > Jim > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at 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 n8hm at arrl.net From billclarke at nycap.rr.com Mon Sep 3 09:48:32 2018 From: billclarke at nycap.rr.com (Bill) Date: Mon, 3 Sep 2018 09:48:32 -0400 Subject: [Elecraft] K3: Audio settings Message-ID: <8e691120-814a-6e37-6ca8-9495295ef1c5@nycap.rr.com> I have been using my K3/P3 since new in early 2013.

I do not consider it worthwhile for my K3 - the DSP board would have to be replaced. There was a change to the K3 DSP board much earlier that added a low pass filter as well as lower frequency audio response to the original K3 audio. For a time, there wa a DSP board swap program to upgrade the DSP board, but that has now been retired, but you can still purchase the low pass filter add-on. If you have the Rev D DSP board, it is already installed. The new synthesizer will get you the most "bang for the buck" improvement in the K3 RF performance, and the new KXV3B adds the 20 dB preamp for 17 meters and above. The KIO3B can add the USB interface rather than the RS-232 as well as an internal soundcard. 73, Don W3FPR On 9/3/2018 10:56 AM, Josh Fiden wrote: > I have two original K3.

The KXIO2 clock is working properly again. I do not know if it was one of the things below or the combination of all of them but I'll share what I did in hopes it might help someone else. My KX2 was purchased used so I do not know if it was assembled by the original owner or by Elecraft. Step 1: I removed external power and the internal battery. Then I let the radio sit for a couple of days so the backup cap could discharge and things would really be "off". Step 2: I removed the KXIO2 board using the installation instructions as a guide. I carefully applied a small amount of DeoxIT "D Series" cleaner to the contacts on the four headers. (Use VERY little, I could barely see that I had applied any.) This was in case there might be any small amount of corrosion that was not visible. Step 3: I reassembled everything, put the battery back in and connected external power. Then, I used the KX2 utility program to set the clock to match my PC with the "calibration value set to "0". I turned the radio off. Step 4: About a day or so later I compared the two times. The KX2 was a few seconds fast so I bumped the calibration to "1". Having done all of that the radio seems to be about a minute fast after a week. Plenty good enough for me and well within what Elecraft claims it should do. Tim N9PUZ On 8/26/2018 11:00 AM, Don Wilhelm wrote: > Tim, > > I would suggest trying again to recalibrate it.?

I do not consider it worthwhile for my K3 - the DSP board would have to be replaced. There was a change to the K3 DSP board much earlier that added a low pass filter as well as lower frequency audio response to the original K3 audio. For a time, there wa a DSP board swap program to upgrade the DSP board, but that has now been retired, but you can still purchase the low pass filter add-on. If you have the Rev D DSP board, it is already installed. > > The new synthesizer will get you the most "bang for the buck" improvement in the K3 RF performance, and the new KXV3B adds the 20 dB preamp for 17 meters and above.

I did that with a string of pre-K3 ?modern? radios (and quite a few vintage radios with puny audio output), including the K3 for a while, before a major downsizing of stuff. Worked and played great. Now I just use a pair of E?craft SP-3s on my K3, which work fine .. and are a lot easier to move around :-) I have no complaints about K3 audio. Since the days of big 6V6 audio in vintage gear (think SX-28, NC-183D, etc), radio vendors have mostly paid attention to everything but audio stage quality. Maybe the new output stage in the K3S makes a big difference .. not owning one, (unfortunately, E?craft didn't make the new main board available for upgrade) I couldn?t say. But if you pick the audio up at line-out and amplify it with a decent amp and good speakers, you won?t be disappointed with the result.

Message-ID: <000001d443d5$64894600$2d9bd200$@telia.com> From: SM4MNC, Leif Hoffmann I have just finished building K2 #7836. A very great pleasure and about a ton of fun too, and I sincerely hope that this "100% solder kit" will remain in the future! My kit was from the summer sale and contained the K2, the SSB- module, noise blanker and antenna tuner. Everything went almost flawless: Under Alignment and test, Part 2 there was absolutely nothing to be heard in the headphones! What now? The problem solved itself when I found the bag with the surface mount IF-amplifier U12. The step to mount it was described in the errata and I had just missed that small detail! When installed, there were no more problems here. I did the initial adjustments, the transmitter and receiver were functioning - perhaps the filters did not match perfectly, but that was a "software-problem" to be solved later! The SSB-unit, noise-blanker, and finally the antenna-tuner were built and put in the radio, and everything seemed to work as it should. What an amazing little radio this is!! Two more things: 1. In my K2 there is absolutely no space between the encoder and the front panel. Not even the best flush-cutter in the world will give enough space there. I have read in the Elecraft Archives of paper-bits etc. I have put on double layers of adhesive tape (tape for electrical purposes) with the advantage that it doesn't get dislodged when you remove the control board next time. 2. During the assembly there were some very small (in value) capacitors, that in my kit not were similar to the pictures in the parts list, but thanks to Stephanie, Leony, Johanna and all the other packers of the subassemblies, I could simply rely on the number of the remaining parts (no more - no less) and after a little examination of the parts, the problem got a solution and as the radio is functioning, it seems that I have got all parts in the right places! Overall I can say that building the hardware actually were "the easy part" and I have learned a lot in the process. Thanks, Elecraft! BUT: I have read, and re-read many times both in the main manual and the manual that comes with the KSB2 concerning the adjustments. The envelope with the filter crystals for the KSB2 were marked E850006 and 3228-1, 180611. I could not recognize any of these as a calibration number between 3.2 and 3.9, so I used 3.6 as described, and when I came to the filter setup I did exactly as shown in table 3 - with catastrophic result !! The FL1 - under OP1 and LSB- were so high-pitch that it was practically useless, and this is the filter-setting that I probably will use the most! With an antenna and the loudspeaker mounted I adjusted the freq. to more like 4914.1 - 4914.2 than the 4913.5 that comes from the table. The ideal would of course be to sweep the filters with appropriate equipment - which I have none! So that now I have all the filters (both for SSB and CW) adjusted "by ear". I do have a radio that I can use, even if it's not optimal. It's pleasant to listen to and a couple of good reports "on air" too. I just wonder: How many of the previous kit-builders have experienced the same problems - and done what I have done? Finally: How accurate are the settings over time? The 4 MHz oscillator on the control board is of course the most critical part here. But - yesterday evening I had the radio adjusted to within +/- 10 Hz compared to my big transceiver. When I turned on the K2 today it was about 320 Hz high. I have - again - re-run the frequency calibration procedure, the CAL PLL and now again the display shows inside of +/- 20 Hz. Can this be a temperature problem? It was rather warm in my shack yesterday and pretty cold today when I came in. The small capacitor C22 is of course critical here! And a small suggestion: The adjustment would be much more calm if there were two trim-capacitors. One 8-50 pF(as C22 is), and in parallel with that another adjustable capacitor on 1-2 pF for the fine-adjustment. Naturally, I don't expect this little radio to have the same stability as my big radio, with its X-tal oven and that can zero-in on WWV to within +/- 1 Hz, but on the other hand, I don't know what to expect from the K2. Will it be within +/- 10 Hz, +/- 100 Hz or perhaps +/- 500 Hz? How will it perform under field conditions? Actually, it is not that very important, as long as my #7836 performs "as expected". Can you say anything about what stability I can expect from a K2?

Either use headphones or good quality external speakers for a good audio sound from the K3. The K3 to K3S options will not improve the K3 audio. The new synths will improve the RX and TX phase noise (and usable sensitivity) considerably, and the KXV3B will improve the preamp selection on the higher bands. The KIO3B is more of an operating convenience IMHO by virtue of its internal USB to USB converter and the internal soundcard. Worthy of adding if you do not have RS-232 ports on your computer. If your operation is mainly casual, you will not notice the difference, but if you are into contesting and DXing, the ability to "saddle up" to a strong station close to your operating frequency will be quite noticeable. 73, Don W3FPR On 9/3/2018 2:46 PM, Bill wrote: > In the real world, is that "theoretical" improvement noticeable?

You can easily optimize your filters and calibrate the dial readings on your K2. The 4 MHz Reference Oscillator only needs to be correct just before running the CAL PLL and CAL FIL routines. At other times, it is not used dynamically and only serves as a clock for the MCU. The DAC values for the PLL and BFO are stored in EEPROM and are used in normal operation for displaying the K2 dial frequency, the 4 MHz Reference Oscillator is not used, and it can drift substantially and not cause any variation in the K2 frequency. The BFO stabilty should be good unless you have mounted L33 in a manner where the toroid can move with temperature, and the "Thermistor Board" provides good temperature stability for the PLL Reference Oscillator. If you experience extreme temperature swings when operating, you may be able to modify the amount of compensation by changing the value of RA on the thermistor board. Download the PLL Upgrade instructions from http://www.elecraft.com/manual/E740046%20PLL%20upgrd%20old%20K2s%20-%20Option%20Rev%20E.pdf for details on how to move the RA value. Your K2 should be frequency stable within a few HZ, but give it 5 minutes for initial warmup. There is information about setting the K2 dial calibration on my website www.w3fpr.com. For optimizing the filter response, the only equipment you need is an audio spectrum analyzer running on your computer, and a broadband noise source feeding the K2 antenna. Band noise on a portion of the band without signals can be used if you do not have a broadband noise generator such as the Elecraft N-Gen. Information about optimizing your K2 filters can be found both at my website and at http://www.mmccs.com/mmarc/n0ss/k2_filters_using_gram_v5r17.pdf If you are running a Windows computer and need Spectrogram, it is available on my website www.w3fpr.com.

We had a phone station at Field Day where the operator used his own rig with an internal speaker (I think it was an Icom), and the sound was so grating to my ears that I thought about cutting his coax! I don't know how the operator deciphered the calls and reports. That is a "to be fixed" situation for next year's Field Day. I was at the CW station where we used headphones with the internal speaker turned up only enough to let others nearby hear what was going on, and it sounded OK, but not great. I should have brought my external speakers for the K3 CW station. 73, Don W3FPR On 9/4/2018 9:50 AM, Bill wrote: > Don, you make me laugh.

If you do not have high quality (Hi-Fi) speakers that you can use with the K3/K3S, then the matching SP3 speakers are an excellent choice. I was fortunate enough to pick up a pair of Radio Shack Minimus speakers at a 2nd hand store for $5.00 each - they do very well in my shack. The speakers that will produce all the audio nuances that are possible are those with a wide range response, so Hi-Fi speakers qualify for that aspect. Others with a restricted audio range such as those with DSP will limit the full range audio available from the K3/K3S. In other words, the audio response of the radio should be clearly reproduced by the speakers. The response by the small internal speaker is necessarily limited, but good wide range external speaker will deliver the sound that the radio is capable of. 73, Don W3FPR On 9/4/2018 5:46 PM, Bob McGraw K4TAX wrote: > Yes, well most of those are good sounding and......are larger than our radios on our desks today.

I managed to solve it today. I also have been exploring other issues suggested regarding RF and current in the shack, and have a choke on its way that should help with that, but I received one part first: a new keyboard. I'd been using a Kinesis Freestyle 2 ergonomic wired keyboard for the PX3, but the new one is an inexpensive Amazon Basics 2.4ghz wireless keyboard. I got right on 30m in PSK31 mode, and got ZERO extraneous characters or other garbage in my keyboard buffer. I didn't have much time to experiment, but did have time to test it on RTTY as well and still got no extraneous characters. My guess is that the stray RF was getting into the keyboard's cable between the two halves of the unique split keyboard. That cable is not shielded, or not well, and was a prime target for stray currents or emissions. The wireless keyboard has no such vulnerability, and thus no entry point for garbage. It also would seem that my brief test on 30m PSK was detected by an operator in Wisconsin, as I got an email from "PropNET", something similar to PSKReporter, that logged my signal. The timing, band, frequency, and mode were all consistent with when I was testing, so I was at least heard 1200+ miles from home on 4 watts. I consider that a win, even though it wasn't a proper QSO. I'll still be taking steps to deal with stray RF and common mode current in the shack anyway -- it's good operating practice in any case.

Since the 12CTRL signal resulted in 5V power at the regulator immediately, I racked by brain trying to figure out why The KAT100 would fail to light the LEDs for seconds, sometimes tens of seconds. I decided the problem might have to do with the U1 clock. I put a scope probe on pins 13 and 14 of U1. While the KAT100 fails, these pins would float up to about 1 volt. When it worked, these pins would be at 0 volts, because the chip is sleeping! (the oscillator doesn?t run while the chip sleeps, to save battery power) So, it looked very much like the oscillator wasn?t starting reliably at power-on. I hit the Z1 resonator with a heat gun, with no immediate effect. Later I nudged Z1 with a screwdriver, and the KAT100 suddenly came to life. Not sure if I had a bad device, or just a bad solder connection, I re-flowed the solder connections to Z1 and to pins 12-14 of U1, where they connect. This seemed to work. I let everything cool down overnight, and checked it again in the morning. Oddly, the K2 was giving Info 080 and the KAT100 was failing again! I didn?t have time to diagnose. Today, however, the K2 powered right up, and the KAT100 snapped to attention, both working flawlessly. At the moment, I?m going to declare the mystery as being solved, and ignore the transient Info 080 issue.

A couple minutes over a "few months" is also rather tight tolerance for the internal clock. Even a computer clock can be expected to drift some unless sync'ed with a time standard regularly. The K3 clock is a similar design. It is not a precision long term timepiece like a watch. So, I have to ask - did you ever observe it over several months some time ago? If so, did it have better stability then? If you do not have the subRX in your K3, it is easy to change the battery, so why not just change it for your peace of mind. OTOH, if you do have the subRX and/or the K144XV, I would suggest monitoring it for several months before deciding to change it. 73, Don W3FPR On 9/6/2018 3:49 PM, Petr, OK1RP/M0SIS wrote: > Hi, > > sorry for stupid question. > > The internal clock seems to delaying for couple of mins during few months on > my K3 (built mid 2008). > > Does it means that an internal battery cell life in my K3 is ending? > From k6dgw at foothill.net Thu Sep 6 16:59:46 2018 From: k6dgw at foothill.net (Fred Jensen) Date: Thu, 6 Sep 2018 13:59:46 -0700 Subject: [Elecraft] K3: Menu entries in K3 macros In-Reply-To: References: <47fc11f4-4a78-fb36-2e9f-8cbd401e81a1@foothill.net> Message-ID: <7b0e2820-4c4a-f695-935b-762af3e83972@foothill.net> Thanks Wayne and Mike, my feeble brain did not register that some menu entries have values and don't just toggle.

An elevated counterpoise would probably be the same. Perhaps two decades ago I modeled single radials and counterpoises, and if my memory is correct I believe they all indicated that the wire should point in the general direction of your desired radiation. The above statements assume your radiator is more or less vertical. My (poor) models showed only a slight advantage in that direction?.possibly only a very few dB. My portable antenna for my KX1 is usually a 17 foot radial laying on the ground and a 26 or 27 foot wire more or less vertical, or an inverted L. This is a very satisfactory portable antenna for 40, 30, and 20 meters. However not equal to my linked dipole with an apex up over about 25 feet which is heavier and harder to set up. Sometimes if this 17 foot wire is elevated, it will still tune all 3 bands, but sometimes I need a longer counterpoise wire to tune it up on 40 meters with the built in KX1 tuner. Probably 2, 3, or 4 symmetrical radials or counterpoise or radial wires would be the best solution if possible. The single radial solution is a compromise which is often enough to get you on the air and make some (good ?) QSO?s.

As a contester I face my biggest SWR challenges are 40m and 80m SSB. On 40, my Yagi is resonant at 7045, and the KPA will give me a full-power match between 7000 and 7125 pretty easily. Anywhere north of there, however, I'm above 3:1, rising as high as about 7 or 8:1 at 7295. On 80, I could use the KPA from 3500 (resonant 3550) to about 3750, but would need to switch to the external tuner for anything above that (I only ever go as high as 3850, and extremely rarely at that. Maybe a dozen transmissions per year calling mults). At the moment, I have a Palstar HF-Auto, which is bypassed everywhere except the phone portions of 40 and 80, and the internal tuner in the KPA that's bypassed only on those two bands. The freeware software for the HF-Auto is positively wretched, and the tuner itself is only RF-sensing, not commanded by band data, so obviously I'm looking for a better solution that will allow me to use full legal limit with fast, seamless switching. I would prefer to use the KPA-1500 for as much of the tuning duties as possible, and only dropping to the HF-Auto when absolutely necessary, since quite frankly I don't trust the Palstar to not go rogue on me (a regular occurrence, sadly). As it stands now, I can set the KPA's internal tuner to operate or bypass on full bands only, not in segments. It doesn't seem like a stretch to allow a user to put in limits within a band. ---------------------------------------------------- Regards, Peter Dougherty From dick at elecraft.com Fri Sep 7 15:59:17 2018 From: dick at elecraft.com (Dick Dievendorff) Date: Fri, 7 Sep 2018 12:59:17 -0700 Subject: [Elecraft] Tuning band segments with the KPA-1500 In-Reply-To: <007501d446d1$f7f191a0$e7d4b4e0$@net> References: <007501d446d1$f7f191a0$e7d4b4e0$@net> Message-ID: The intent is that the tuner does this already in normal practice. If you press the ATU tune button at a frequency where the antenna SWR, with the ATU bypassed, is ?low enough?, the ATU setting stored and later recalled is ?ATU bypassed?. Both ATU LEDs are lit when this happens. The relays for this situation are exactly the same as if you turn the ATU off. You can influence the SWR for ?good enough? with a KPA1500 utility function, edit configuration, SWR threshold for SWR bypass. It?s per band and defaults to 1.2 to 1. The amp is rated at 1500w for a 3:1 or better antenna. At 10:1, you?ll need to dial back below 1500W to avoid damaging the ATU. This is what the power too high for bypass SWR fault is for. If the antenna is 10:1, figure on about 850W. The amp does better if the SWR the PA sees is low. 73 de Dick, K6KR Sent from my iPhone > On Sep 7, 2018, at 10:41, Peter Dougherty wrote: > > Is it possible (or might it be possible with a firmware upgrade) to selectively > use the KPA-1500's tuner on only a portion of an individual band? > > As a contester I face my biggest SWR challenges are 40m and 80m SSB. > > On 40, my Yagi is resonant at 7045, and the KPA will give me a full-power match > between 7000 and 7125 pretty easily.

(Apologies to linguistic purists.) A simplified definition might be: A. long enough to work within the maximum limits of the ATU's L-network on the lowest band used B. presents a reasonably low impedance on all bands used (e.g., doesn't look like an end-fed half-wave) ATUs have limited monotonicity and granularity, as well as stray impedances, so in practice there is a third criteria: C. tunable on each band used despite specific L-network idiosyncrasies This third criteria is the hardest one to predict for a given ATU design, as the idiosyncrasies vary with PCB layout and actual component values. They may only impact the highest bands, or for a particular antenna, the bands on which Q is the highest. For our ATU designs, we try to minimize strays and keep the network monotonic by using tightly toleranced capacitors and toroidal inductors. While a wide range of wire lengths will meet the requirements of a "KRA" in the field, we've found from experience that something in the 25'-28' range works on all bands from 40 meters up, and roughly twice this for 80 meters up. Since it's impossible to predict the effect of ground losses, obstructions, deployed wire angles, etc., you may occasionally need to add or remove wire to obtain resonance on all bands used. 73, Wayne N6KR Tom WB2QDG K@ 1103 On 9/6/2018 11:57 PM, JEROME SODUS wrote: > Hello, > > > I want to re-read a post that Wayne n6kr made about a wire-antenna tossed up a tree and the location of a counterpoise; this was relative to portable operating a kx2 or kx3, if I recall correctly. > > > But my archive search has come up empty. > > > My recollection is he recommended placing the counterpoise in a direction opposite to the wire-antenna. > > I need to verify that recollection. > > Hopefully someone has saved that post. > > TIA for any help. > > 73 Jerry km3k > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at 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 thom2 at att.net > -- I'm happy to be anywhere -- Keith Richards From donwilh at embarqmail.com Sat Sep 8 10:13:54 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 8 Sep 2018 10:13:54 -0400 Subject: [Elecraft] searching for post by Wayne n6kr about counterpoise In-Reply-To: <1201e0a0-2f4a-b2a5-4f5c-cbf8b9fcc32c@att.net> References: <703522120.10144.1536292659639@connect.xfinity.com> <1201e0a0-2f4a-b2a5-4f5c-cbf8b9fcc32c@att.net> Message-ID: Tom and all, One of the KX2 Field Testers found that a 58 foot resonator and a 26 foot counterpoise worked well on 80 through 10 meters. I use half those lengths for 40 through 10 meters. No feedline, both the radiator and the counterpoise are connected directly to a BNC to Binding Post adapter on the KX2. The direction of the counterpoise does not make a lot of detectable difference. Antenna modeling may show some difference, but working quickly in the field may not allow you to set up the "perfect" situation - use what you have available. The KX2 internal tuner is a wide range tuner that might even be able to match a metal window frame or the proverbial "bedsprings". Let's face it, this is a compromise antenna that can be thrown into a tree and give us the opportunity to make QSOs in the field. For home station use, a proper antenna up in the air will be better. 73, Don W3FPR On 9/8/2018 9:50 AM, Tom McCulloch wrote: > This is probably NOT what you are looking for but it's about random > length antennas...it goes back to Jan 29, 2017. > > hope this helps: > > I'd call an ad-hoc antenna that works on multiple bands with an ATU a > "Kinda-Random Antenna" (KRA).

For use on 30/20 m only, as little as 12 ft. can be used, and for 20 m only, as little as 8 ft. Avoid lengths which are close to a half- wavelength long or any multiple thereof, which will be out of the KXAT1's matching range. For example, you should avoid using close to 33' if 20 m operation is planned, or 46' if you'll be using 30 m. Use a at least one ground radial, cut to at least 1/8th wavelength on the lowest band used (16' on 40 meters). When possible, use two or more radials, with one cut to 1/4 wavelength on each band.? http://www.elecraft.com/manual/E740054%20KXAT1%20man%20rev%20B.pdf The KX2 manual has slightly different recommendations on page 10. "The wire tied to the red post (antenna hot lead) is attached to a tree or other tall support. The wire tied to the black post (radio chassis ground) is the equally important counterpoise, which is typically laid on the ground. A length of about 25 feet for each wire, matched to the KX2?s output using an antenna tuner (see ATU, pg. 11) will typically provide good performance on 40-10 m." http://www.elecraft.com/manual/E740282%20KX2%20owner%27s%20man.pdf I?ve been using 26 feet in the air and 16 feet on the ground. As for a single counterpoise/radial, there will be more radiation in the direction of the radial. The radial reduces ground losses in that direction. The directions without radials will have more ground loss and thus less signal. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Sep 8, 2018, at 6:50 AM, Tom McCulloch wrote: > > This is probably NOT what you are looking for but it's about random length antennas...it goes back to Jan 29, 2017. > > hope this helps: > > I'd call an ad-hoc antenna that works on multiple bands with an ATU a "Kinda-Random Antenna" (KRA).

Message-ID: <64325923D22D427C94FFDFDD1C191CF1@JRPC> I am using my KX3 as a WSPR beacon at 500mw with a Arduino based controller which provides GPS time sync, WSPR data, and audio. Currently I am running mono band at 1 two minute transmit cycle per 10 minute time block. Now I want to add KX3 band switching to my controller and increase my T/R duty cycle. Watching the PA.I current I see that my current 2 minute ON 8 minute OFF cycle shows a 30c ON ? 46c OFF temp range. Running a 2 minute ON 2 minute OFF cycle shows a stabilized 36c ? 49c range after about 5 ON/OFF cycles, and running continuous transmit cycles stabilizes at 48c ? 53c after 6 cycles. So based on these 3 duty cycles I see a 16c, 13c, and a 5c temperature rise. The 2 on/8 off has the lowest max temp but the widest temp range, the continuous transmit has the highest max temp but the lowest range. My plan would be to have my controller switch the KX3 through 5 bands transmitting the 1 minute 53 seconds on a band and switching to the next band during the 7 second opening. I have done extended temperature calibration with the XG50 so frequency stability should not be a issue. My question is, 53c (127f) is hot, are there any thermo stress issues to the PA or the KX3 in general with running any of these three duty cycles? Obviously I don?t want to damage my KX3.

Look at the specs for semiconductors and you will find that is only a medium temperature. Actually at 500mW, it is unlikely that the KX3 will be damaged by even a continuous key-down. If you are operating it outdoors, you should keep it out of direct sun. If it concerns you, I would suggest adding one of the aftermarket heatsinks. 73, Don W3FPR On 9/9/2018 12:11 PM, George Pasek wrote: > I am using my KX3 as a WSPR beacon at 500mw with a Arduino based controller which provides GPS time sync, WSPR data, and audio.

I often work DX contests running 5W, including most 160M contests. The stations that are able to work me are those with good RX antennas. That matters a lot in contests like the Stew Perry, where each contact is scored by a formula that includes multipliers for distance and for the power used on each end.? The guy on the other end of a QSO with a QRP station gets extra points for that QSO. A few years ago, I was attempting to work three DXpeditions that were around the Antarctic circle on 160M. I was running legal limit, and they could hear me, but the hardest part of the QSO was me hearing them, thanks to my local noise. I worked all three of them, but at least one of them would not have made it into the log without the Beverage I have pointed in that direction. I also do a lot of contesting running legal limit, and in some contests where power is limited to 100W. I have very good TX antennas for 80 and 40, so a lot of east coast stations are calling me, often with not so good antennas. I'm able to hear and work more of them because of the Beverage I have pointed in that direction. Not everyone benefits from RX antennas -- those who don't care to work weak stations, and those with very low local noise levels, for example. And not everyone CAN install RX antennas -- most of us are lucky to be able rig a TX antenna. That was my situation when I lived on city lots in the middle of Chicago, and even in the WV city where I grew up! 73, Jim K9YC On 9/9/2018 5:58 AM, hawley, charles j jr wrote: > The ARRL recently published a book ?Receiving Antennas for the Radio Amateur?.

Hams in the 40's and 50's [and probably before] used one antenna because antennas are expensive and require space.? None of the ham community I knew when I was first licensed in pre-transceiver days [1953] used separate receiving antennas.? I remember being given a Dow-Key coax relay with a movable spring-loaded pin on the receive side that shorted the RX when in TX for the first TX I built from scratch [2 807's in PP to cancel the 2nd harmonic of 10 m in Channel 2]. Transceivers came along near the end of the 50's and were undoubtedly a huge motivator for the shift from AM to SSB since you were guaranteed to transmit and receive on the same frequency, removing one of the difficulties of separate TX and RX, and zero-beating with no carrier.? Separate RX antennas were the rule in maritime CW at the time, TX and RX sites were separated by miles. Separate RX antennas sort of crept into the ham vernacular much later, mainly in the context of large contest/DX superstations. It is certainly true that while a Beverage RX antenna can produce a really desirable S/N ratio over the TX Inv-L on 160, and you would never want to TX on it, the reason most of us do not have Beverage RX antennas is we don't own enough land.? I believe that Don Wallace, W6AM, who definitely owned enough land had several Beverages scattered around under the multiple TX rhombics.

It's a very inefficient antenna and wouldn't radiate worth a crap. On the low bands we're looking for increased signal to noise ratio NOT maximum gain. 160m verticals can be pretty efficient radiators. They stink on receive because of noise caused by arrival angels and polarization. They hear equally badly in all directions at once. On the high bands nothing beats a yagi/quad/log, mainly because of their increased gain and efficiency compared to the alternatives. With a yagi/quad/log you can point the "gain" in your favored direction and turn your back on "noise". The gain of a yagi/quad/log works equally on TX and RX. R.

It's a totally meaningless reference. Antennas are generally (as in almost always) reciprocal between transmit and receive, so if you suck on transmit you're likely to equally suck on receive. So yeah ... most of us probably can work anything we can hear but that doesn't mean anything other than we haven't managed to screw up the physics of the world. > > 73, > Dave AB7E > > > >> On 9/8/2018 5:00 PM, Fred Jensen wrote: >> During the runup to Cycle 19 [!1957 for me], it was said you could work anything you could hear on 10 with 20 watts to the window screen.

AND -- propagation reporting systems like WSPR and the Reverse Beacon Network (RBN) can provide very good comparisons between antennas IF a LOT of reports from? a LOT of stations is averaged over a LOT of time. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at 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 farrerfolks at yahoo.com From k6dgw at foothill.net Sun Sep 9 16:26:35 2018 From: k6dgw at foothill.net (Fred Jensen) Date: Sun, 9 Sep 2018 13:26:35 -0700 Subject: [Elecraft] ARRL book on receiving antennas In-Reply-To: <97EEB4D9-8B0C-4881-83B9-8C83D438628A@blomand.net> References: <451007983.2122219.1536521144222.ref@mail.yahoo.com> <451007983.2122219.1536521144222@mail.yahoo.com> <2028736865.2530985.1536521775974@mail.yahoo.com> <97EEB4D9-8B0C-4881-83B9-8C83D438628A@blomand.net> Message-ID: <3e683f75-0c0d-99bb-8912-621a8cacfc20@foothill.net> It's the double integral of the power [watts] over all elevation angles 0 to Pi and all azimuths 0 to 2Pi divided by the power [watts] dissipated in the radiation resistance at the feed point.?

But how you measure it? With practical measurement equipment, it is difficult to isolate to a single plane. That may be do-able with fully characterized equipment in a controlled antenna field space or in an EMC lab, but it certainly is not practical in a typical ham antenna installation - and even the radiation resistance is not easily measured. Antenna modeling done properly will provide a much more easily produced result. Comparative results between different antennas can be obtained from a reference pickup antenna, but that can only show the relative performance, we still have to guess at the efficiency. 73, Don W3FPR On 9/9/2018 4:26 PM, Fred Jensen wrote: > It's the double integral of the power [watts] over all elevation angles > 0 to Pi and all azimuths 0 to 2Pi divided by the power [watts] > dissipated in the radiation resistance at the feed point.?

In recent years vertically polarized man-made electrical noise has been a growing problem. I was forced to use a dedicated receive antenna to mitigate severe local noise problems (switching power supplies, plasma TVs etc.) from my surrounding neighbors. Because the only practical transmit antenna option was a vertical (little space), I had to give up on it as a receiving antenna. After some experimentation, I settled on what is essentially a folded dipole antenna cut for 40m, which is very close to the ground. It's about 60 ft long and the wire spacing is about 4 ft, with the lower wire only 2 ft from the earth, with a balun at the feedpoint in the middle of the higher wire. 50 ohm coax runs from the balun to the shack, lying on the ground to further minimize noise pickup. It is strung along a fence on the lot line. On all bands from 40m to 15m, the difference in signal to local noise ratio between it and the vertical transmit antenna and this antenna is considerable, up to 15dB. I suspect it would be a terrible transmit antenna, but it works fine as a receive antenna. DX signals are often heard by it much better than on the vertical. I don't have problems with the transmit signal overloading the receiver input, perhaps because they are polarized differently. The folded dipole feedpoint is about 50 ft. from the vertical antenna. The advantage of the separate receive antenna is that I can use an NCC-1 phasing system box in conjunction with the handy RX ANT In/Out insert point on my K3. It's configured to use the Tx antenna signal from RX ANT Out as the noise signal into one of the NCC-1 inputs, with the other receive antenna connected to the other, and the NCC-1 output connected to RX ANT In. The difference in vertically polarized local noise pickup between the antennas lets me get a deep null on any particular noise source in the surrounding houses. The effect is to allow me to operate when I'd otherwise have to give up and be content with watching the man-made noise waveforms dance around on the P3 screen. Using the NCC-1 introduces a directional effect of course, but as long as the signal isn't arriving at exactly the same azimuth as the local noise it works well. I think that a lot of folks afflicted with strong local noise are using small so-called magnetic loop antennas for the same reason. At times I feel like the Grinch in "How the Grinch Stole Christmas", muttering "...the noise noise noise!". 73, Bob NW8L > title, you're going to have to make a case for them even if you have to > stretch a bit. > > I remember bolting a 115 VAC coil Dowkey relay on the back of my DX100 for > antenna change over in 1960 or so.?

I read the High Temp Limit is set for 60c so I figure I was not dangerously high but just wanted to check if there might be a mechanical preference between the shorter duty cycle with the lower temp but larger temp swing causing more of a expansion contraction issue over time or the higher duty cycle with higher temp but not near as much heating cooling. I know that on some devices the thermo stressing of components due to repeated heating cooling cycles is a issue. This will probably be in continuous use for a while so my concern is the long term effects. I will keep a watch on the temp and maybe add the heatsink as you suggested. tnx George WD0AKZ -----Original Message----- From: Don Wilhelm Sent: Sunday, September 09, 2018 11:30 AM To: George Pasek ; elecraft at mailman.qth.net Subject: Re: [Elecraft] KX3 WSPR Thermo Stressing? George, Actually 53 degC is not that hot. Look at the specs for semiconductors and you will find that is only a medium temperature. Actually at 500mW, it is unlikely that the KX3 will be damaged by even a continuous key-down. If you are operating it outdoors, you should keep it out of direct sun. If it concerns you, I would suggest adding one of the aftermarket heatsinks. 73, Don W3FPR On 9/9/2018 12:11 PM, George Pasek wrote: > I am using my KX3 as a WSPR beacon at 500mw with a Arduino based > controller which provides GPS time sync, WSPR data, and audio.

Just gather all the watts actually radiated by the antenna and divide it by the watts you put into Rr.? Unfortunately, I did not really address Bob's question ... "How do you sweep up all those watts?" :-)? That is a nearly intractable problem at HF unless you'll tolerate significant inaccuracies and assumptions.? It's much easier at UHF and uWaves. An alternative is to measure/compute the losses.? Did something similar on a 10 KW FM broadcast TX, calculating the power it took to heat the exhaust air on the premise that the rest went up the coax to the antenna and I knew what the PA input power was. KFBK in Sacramento CA [1530 KHz] eliminated a lot of the unmeasurable variables by employing a Franklin antenna [center-fed half-wave vertical] over the rice fields of the southern Sacramento Valley [nearly always standing water, and always wet]. The center-fed vertical exhibits far less ground losses than bottom-fed monopoles ... at 50 KW, it's colloquially known as the "Flame Thrower of Sacramento."? It may be the only Franklin left in NA.? KFBK is also famous as the birthplace of the RCA Ampliphase transmitters and the radio birthplace of Rush Limbaugh. NEC models coupled with terrain models can be used to establish upper and lower bounds on antenna efficiency with pretty good fidelity to reality.?

We wanted to compare the new antenna against the big rhombic that had been used for many years for the 20 meter bulletin and code practice transmissions. So, for a week or two, we did test transmissions after each scheduled transmitting session. We would switch between antenna "A" and antenna "B", send long dashes, and ask listeners to send in QSL reports. (Which antenna was "A" and which was "B" varied randomly for each test.) I collected the reports and plotted them on a map of the US. We found that the rhombic was a little better directly on its boresight to the west (toward southern California from Connecticut) but the stacked Yagis had a much wider beamwidth so were better over the country as a whole. By the way, you don't have to transmit to compare two antennas if your receiver has an accurate S meter. Just switch between the antennas and compare S meter readings.

I'm familiar with measuring broadcast fields for both directional and non directional systems.? The variances over the seasons with varying moisture levels in the ground and the difference with and without vegetation is clearly measurable and predictable.? But still the efficiency of the radiator was not clearly defined. As to hams, I suppose we individually evaluate a given antenna under the conditions we have available.? From that we can say that given antenna ZZ is more or less efficient than antenna XX.? What ever that XX antenna happens to be.? While others may say that their XYZ is the best antenna they have? ever had,? this may be true, that is until one may find another antenna to be better. What ever "better" is defined.?? And again, each of us will have objectives in terms of what our antenna and station must attain.??? As Rob Sherwood said when asked "what is the best receiver", his answer; "what ever satisfies your needs and you feel as comfortable to operate and can afford". ? ? I suppose antennas are much in the same vein of characterization. Yes, at VHF and UHF there are means and facilities to accurately measure antenna efficiency.?? Usually we find those to be in the 60% to 80% range.? Unfortunately some of the applied power is converted to heat, the result of IR loss,? and thus is lost in terms of electromagnetic radiation. ?? Again the means and the equipment required, as Jim K9YC stated, generally is well above and beyond the means of most hams.???? Some years ago I was fortunate to have supervised access to the antenna test range at the Motorola facility in Florida and also at the anechoic chamber owned by IBM in S. FL.?? These supported my graduate studies. No further answers required on my part.?? I've launched into a "reading" project to further educate myself on the topic. 73 Bob, K4TAX On 9/9/2018 5:48 PM, Fred Jensen wrote: > Yes, very straightforward theory.?

"The WWV antennas are half-wave vertical antennas that radiate omnidirectional patterns. There are antennas at the station site for each frequency. Each antenna is connected to a single transmitter using a rigid coaxial line, and the site is designed so that no two coaxial lines cross. Each antenna is mounted on a tower that is approximately one half-wavelength tall. The tallest tower, for 2.5 MHz, is about 60 m tall. The shortest tower, for 20 MHz, is about 7.5 m tall. The top half of each antenna is a quarter-wavelength radiating element. The bottom half of each antenna consists of nine quarter-wavelength wires that connect to the center of the tower and slope downwards to the ground at a 45 degree angle.

I am getting power out on the LP-100. Any ideas on what I could be missing? 73, N2TK, Tony From alan at wilcoxengineering.com Mon Sep 10 19:44:17 2018 From: alan at wilcoxengineering.com (Alan D.

This is the industry standard handheld meter for electronics work. 4.5 digit display, 0.05% accuracy, extensive capacitance measuring capability, temperature measurement with included probe and legendary Fluke quality / reliability / durability. This model is still in production today and is Fluke?s top-of-the-line electronics handheld meter. I purchased this new in 2010 and it has since been used only in my lab while I had my consulting business. I?ve since retired and moved to a condo, so no longer have need for an instrument of this accuracy. This unit is in mint condition. It has always worked perfectly. Your purchase includes the meter, all original accessories including probes, the thermocouple probe, original box, manual, paperwork and DVD. I?m also including another like-new set of Fluke industrial probes with interchangeable tips, including alligator clips, clamps and clip-on hooked probes. Also included are some Probe Master mini-clip-on probes, BNC adapters, etc. The street price for this meter is currently $387. I?m asking $220 for the meter, accessories and additional extras including USPS insured Priority Mail shipping to the lower 48. Payment via PayPal. Photos by request. Contact me via email if interested. My email address OK on QRZ.

AMBC ground systems would still be needed (unless sited over salt water) to maximize ground-wave coverage even if they were center-fed vertical dipoles. The field intensity produced by a ground-mounted, center-fed 1/2 wave dipole is the same as a voltage-fed (at the tower base) vertical radiator. The majority of omnidirectional, high-power AM stations use anywhere between 180 to 195 degree towers, voltage-fed at the base. In essence, they behave like vertical dipoles and in each case, they employ extensive radial systems. With either feed, maximum RF current occurs at the mid-point, and maximum voltage at either end. I don't recall if the Franklin was developed before or after studies showed that multi-lobe skywave radiation is minimized with 190 degree monopole radiators. That's the reason why so many legendary high-power stations use a tower height slightly longer than a half-wave while ground field intensity is essentially identical to the half-wave radiator.

AMBC ground systems would still be needed (unless sited over salt water) to maximize ground-wave coverage even if they were center-fed vertical dipoles. The field intensity produced by a ground-mounted, center-fed 1/2 wave dipole is the same as a voltage-fed (at the tower base) vertical radiator. The majority of omnidirectional, high-power AM stations use anywhere between 180 to 195 degree towers, voltage-fed at the base. In essence, they behave like vertical dipoles and in each case, they employ extensive radial systems. With either feed, maximum RF current occurs at the mid-point, and maximum voltage at either end. I don't recall if the Franklin was developed before or after studies showed that multi-lobe skywave radiation is minimized with 190 degree monopole radiators. That's the reason why so many legendary high-power stations use a tower height slightly longer than a half-wave while ground field intensity is essentially identical to the half-wave radiator.

A standard USB cable is all you need between the computer and the K3S. Be certain you do not accidentally try to plug it into the RJ-45 jack because that will damage the jack. Make certain the RS232 menu parameter is set to USB. If you also have the P3, you should be using the CBLP3Y cable between the K3S and the P3 (and the setup is the same as the USB). If you are currently using the RJ45 dongle on the K3S to connect with the P3 and plugging an RS-232 cable (or adapter) into the P3 PC connector, that should work too. If this is the connection you have to the PC, set the RS-232 menu to 38400 baud. You must tell WSJT-X which COM port is connected to the K3S - yes, a USB port with an adapter inserted will have a COM port assigned by the computer. That also goes for the K3S connected with a straight USB cable (the USB to RS-232 adapter is in the K3S). 73, Don W3FPR On 9/12/2018 4:06 PM, Richard wrote: > K3S, Mac Sierra 10.12, WSJT-X version 1.8.0. > > Everything is working perfectly.

It was ten feet long on the vertical end sections, something like 40 or 50 feet long on the horizontal sections, fed in the middle of one of the ten foot verticals, and the lower horizontal wire was about five feet off the ground.? The idea was to get low angle vertical radiation with some broadside gain, which in retrospect was a dumb idea given the horrible ground conductivity in that area.? It turned out to be the very worst antenna I've ever used for Field Day and we had our worst score ever as a result ... and this is from two guys who in the year 2000 (with totally different antennas ... hi) set was was then the all time record for 1B 2OP - Battery with 970 QSOs and an even 10,000 points.?

I was cleaning my bedroom, and since my radio was in there, I had it on tuned to the 15 meter cw band while doing my chore. A weak station started calling cq on the frequency I was tuned to. It was a German station, so I answered his call. After exchanging names, RST, and QTH's, he told me that he had a visitor in his shack from my hometown. I asked him if his visitor's name was Hank. You could hear the excitement in his cw as he confirmed the name. You see, Hank's daughter and her boyfriend had been at my house the evening before for a visit and dinner and Hank was one of the topics of conversation. After about a thirty minute QSO, mostly about Hank and his family, I took my copy of the QSO to his daughter to share with her and her family. Since Hank was in the Air Force, he was gone from home a lot and this QSO was very special to them. And I can't even imagine the odds of this coming together. And the room cleaning probably didn't get finished that day. BTW, the rig was a National NCX-5(loved that radio). Antenna was a dipole about 15ft. up in a pine tree. George NC5G (ex.

The antenna was lifted over his head and placed in the cradle at sunset. Two hose clamps held it down, tightened, likewise, with his arm reaching above his head. His safety belt was a piece of rope tied around his waist and the pipe. There is no limit to the love and dedication a Father will go to to support and encourage his son.

You need to have the FTDI drivers. You can download them from https://www.ftdichip.com/FTDrivers.htm. The first step is to get your computer to enumerate the COM port associated with the USB to serial adapter. Having that number, put it into the KX3 Utility PORT tab and Test Communications.

In fact you probably should uninstall them to allow the Apple drivers to do their job. But this isn?t an I/O issue. This looks like there is a corrupt file the application is trying, but failing to read. There should be a crash dump that was created when the program crashed. Open the Console app (in /Applications/Utilities) and look in the various directories it shows for an appropriately named crash log. That should tell us a lot more. One question - did you try to copy a file from a Windows machine into the Mac for this application? Perhaps David (the app author) might want to jump in here as well. He might have a much better feel for why we are seeing these errors. 73!

If so, the other thing to consider is the adapter to the TRRS plug and the audio levels for Microphone or Line in your computer. Make sure you computer does not have the mic disabled. If windows, check the soundcard settings - there is something similar with a Mac, but I am not a Mac user. Recent upgrades to Windows do mute the microphone or line input. 73, Don W3FPR On 9/14/2018 11:48 AM, ke1b at richseifert.com wrote: > > I am trying to connect a KX2 (which has a standard headphone output and microphone input on separate 3.5mm jacks) to a laptop that has an integrated (4 pin TRRS) microphone input and sound output.

As Jack mentioned, the FTDI drivers are now provided by Apple and are included in all versions since OS X 10.9. You should uninstall the D2XX drivers.? Also try deleting the KX3 Utility app, and it's preferences file, and download again from the Elecraft web site and reinstall. The preferences file is located in the /Users/your_user_name/Library/Preferences folder on the Mac. The Library folder is usually hidden. A quick way to get there is to click the "Go" menu in Finder and press the "option" key. The Library folder will then appear in the Go menu. The KX3 Utility preferences file is named "KX3UtilPrefs".?

First, I verified that the audio output from the KX2 was working; it drove a pair of headphones just fine. Then I verified that the external mic input to the computer was working; I connected a real microphone and was able to record audio using Audacity. Then I thought about it, and realized that the KX2 output is STEREO, whereas the computer mic input is MONO. So I tried a MONO 3.5mm cable instead of the stereo cable, and voila! Audio going from the KX2 to the computer, verified by making a couple of FT8 contacts. Thanks to all that responded. FYI, this is a real minimal configuration. The ?computer? is an Asus Transformer, 1 lb tablet running Windows 10, and the radio is a KX2. I can carry the whole shebang in one hand. Plan to use this with a Buddistick from French Polynesia, going to Moorea and Bora Bora next year. Probably won?t be able to work many NA with only QRP and a Buddistick, but I?ll see what I can do.

This may be true for Mac laptops mic inputs as well. So if your KX2 has audio out with nothing connected, you might try that. As the mic jack has DC on it to power the microphone it assumes you?re plugging in, you?ll obviously need to capacitively couple your audio source. The 2k resistor draws the DC current to fake out the Mac into believing you plugged in a mic. I shot 2 days trying to track this down when it happened to me. > Now that I have a *working* configuration (with a simple mono cable), I may optimize it by making a cable that takes the two stereo outputs from the KX2, puts a series R-C combination on each (a few hundred ohms and a microfarad or more, to block the DC), and then ties them together to a mono plug. That should work and keep everyone (the computer and the KX2) happy.

Our mains power had been out for about 18 hours. I fired up my KX1 (on internal batteries, it reported a mighty 1.8 watts into my OCF up 15' on 20 m.) at about 20:00. My CQ call was answered by a gentlemen in Ohio who identified himself as a clergy person. After comforting me with compliments about how good my signal was, he ended the QSO by wishing me, "May God richly bless you and give you light." About 15 seconds, the lights came back on.

Last Saturday?s physics-be-damned results: several solid SSB QSOs on 20 and 17 meters all over the country, including KH6, with a prototype AX1 dual-band whip and a KX2 used HT style.

Thus if phased correctly, and we are only using one mike, the positive modulation peaks will be greater than the negative modulation peaks.? There is advantage to this with regard to AM stations.??? At the same time, when multiple mikes are used then they all must be "in phase" in order to prevent a comb effect of frequency cancellation.? It is standard convention that a positive pressure on the mike diaphragm, then amplified to the speaker system causes the cone of the speaker to move forward or compress the air into the room.? Positive pressure thus causes positive pressure.?? Some audiophiles claim they can hear the difference.?? The jury is still out on that point. From a SSB point of view, it starts basically a modulated carrier, i.e. AM, which then has the carrier suppressed by the balanced modulator, and then one sideband removed by passing the DSB signal through a sharp and steep side filter to produce SSB.?? Hence, then one can theoretically attain more positive modulation than negative. ? Don't confuse amplitude energy with frequency spectrum energy. ?? At the same time, in a SSB transmitter, excessive audio can over modulate the carrier, before carrier suppression and before the sideband filter, and the same effect as over modulating an AM transmitter will exist.? Distortion and splatter. ?? Look at the opposite sideband of a signal on the air while using a SDR or spectrum display.? Clearly some signals will show these artifacts while others do not exhibit the artifact. Final rule, except in a SSB transmitter the positive output is limited by the available capacity of the amplification stages which must remain linear.? In the SSB world,? maximum PEP value capability is the ceiling.? On the other hand, in an AM transmitter, the modulation must be limited to 100% negative so as not to cut the carrier, but can be allowed to exceed 100% positive, in fact upwards of 125% to 135% is quite normal, as long as the transmitter is capable of handling the increased positive peaks without distortion.?? Makes for "loud" AM stations.? And of course there are "processors" which control the negative going values while enhancing the level of the positive going values in order to enhance the modulation. ? Of course if the hams AM transmitter is not capable of 135% positive modulation, splatter and distortion would be generated making for unfriendly neighbors near the frequency. Oh my, this is a lot more than I care to recall. 73 Bob, K4TAX On 9/14/2018 3:24 PM, Nicklas Johnson wrote: > An audio engineering friend noticed in some voiceover recordings something > that I've also noticed in my own waveforms, that a lot of the time, human > vocal cords seem to produce a biased waveform (seemingly a positive bias > most of the time). > > I vaguely remember reading either here on this list, or maybe in QST, > something about this as it relates to setting microphone gain (and bias) so > that the resulting modulated signal is making more efficient (I'm probably > not remembering the right word) use of the available amplitude (ie, not > hitting the peak early on the positive side, but falling well below it on > the negative side). > My Google-foo isn't working out for me today though; does anyone remember > an article or posting on this topic and/or have a link to it?

WAY back in the '50s, AM broadcasters used a device that constantly monitored the waveform and constantly flipped the polarity to keep the hottest peak so that it increased instantaneous TX power.? That's because with AM, distortion is created at carrier cutoff.? I remember building a negative peak clipper circuit back in the '50s. Here's an AES paper by R A Greiner (and probably one of his EE students) that studied the audibility of absolute polarity (that is, the same polarity in the playback system as in the recording system). http://www.aes.org/e-lib/browse.cfm?elib=6950 Several recording and sound engineers who were members of a professional organization called SynAudCon demonstrated that they could accurately tell by listening whether the polarity of a system was correct. Note that we're NOT talking about polarity difference between channels of a stereo recording. 73, Jim K9YC On 9/14/2018 2:13 PM, Bob McGraw K4TAX wrote: > From my AM broadcast days and my pro audio days, yes it is not unusual > to find that a given mike has more positive output than negative > output in terms of the voltage waveform.

I have heard of some builders who have reduced the height of C135, but that is a risky situation, you may short the plates of the capacitor rendering it useless. A better solution is to replace it with a capacitor that is smaller. Do you have the KSB2 kit? If so, there is a spare small 0.01 uF capacitor in that kit. It has leads for .1 inch lead spacing, but spread them out so they will go into the holes in the RF board. If you do not have the KSB2, but do have the KPA100, you can borrow one of those small capacitors from the KPA100 kit and order a replacement p/n E530019 - 0.01uF capacitor 0.1 inch lead spacing from parts at elecraft.com. 73, Don W3FPR On 9/14/2018 8:37 PM, AE0MM via Elecraft wrote: > C135 on my K2 RF board sits 1.1mm higher than the 2d fastener.

I had a NC101X receiver that my dad bought for me at Henry Radio on Century Blvd in LA for $60. While waiting for what seemed like decades for my license to arrive, I built a 6AG7 crystal oscillator for my transmitter. I had one crystal at 7085. My license finally arrived and I was officially KN6HMO. I called CQ endlessly and no one answered. I set up schedules with a few locals a few miles away and they heard me, but no one else. A few weeks later someone gave me a 815 dual tetrode. I went through my junk box and found enough parts to build an amplifier. I tested it by listening on my receiver to make sure that the output was tuned to 40 and not some harmonic. The sun went down and I started sending CQ. A station in Texas returned my call. It was a thrill that hasn't been repeated in the following 65 years.

I enjoyed a short SSB QSO today from ZL with K6JL (Terry). And while I am sure Terry?s station was doing a lot (all) of the hard work- the station at this end made it a lot of fun - new K2 built a few months ago running around 13W into a 43? mostly random wire - one end at about 22? (Squid pole) and a counterpoise of the same length.

Here is a link to the diagram used in the video. My only connection to Win4K3Suite is that I'm a happy customer and continue to be impressed by how stable it is and how well it facilitates the creation of virtual K3 CAT feeds which are transparent to software and hardware you are using in your shack. The video is very detailed and if you find this interesting, you might find it useful to jump back 10 seconds and forward 10 seconds at a time using the 'J' and 'L' keys while you are watching from youtube.com.

For example about 3 years ago I decided to try QRP CW on 160 meters. I live in Alaska and the nearest significant ham population is in Seattle, which is about 1500 miles away. I have an inverted L and only a mediocre radial field. QSO?s over about 1500 miles have usually been quite difficult if not impossible with my 100 watt rig. For a transmitter, I quickly constructed a breadboard 5 watt battery powered transmitter, which probably did not meet FCC specs, but my reasoning was that the nearest active hams were over 40 miles away, and probably no one would hear my flea powered rig anyway. I did not have a battery powered receiver, so I tacked on temporary 1500 pF capacitors across each of the 80 meter antenna coils in my trusty modified KX-1. Previously the KX-1 was rather deaf on 160 meters, but with the mod it received about the same as my regular station receiver. In only a few hours of operation in 2 or 3 contests I worked about 6 west coast states, Texas, and Japan. Most of the QSOs were over 2000 miles. I was very surprised that this would even be possible. So please continue to try things which seem to be logically impossible. If you have a KX-3, go out in the woods during the next contest and try 160 meters, perhaps with a low dipole in the trees. Good regional contacts should be very possible, and with none of the noise present in urban areas should be a very relaxing experience.

I brought my KX3 along, and one evening I had a few spare minutes while camped near the Sophie Islands.? I threw my wire up in a very wet tree, and laid out a counterpoise on wet, thick underbrush.? I didn't have a chance. I tuned around a bit on 40 CW, and to my astonishment heard a guy also camping out on a lake in Arizona, having a QSO with another station.? When they were done I called him, signing WD6DBM/VE7.? He kept calling QRZ QRZ, but eventually we made it.? What a thrill!? Wire in a tree to wire in a tree!

I placed 5th in North America and worked all over the world. I went fearlessly up and down the band answering CQ's, most of which answered my first call. I guess I should mention that my antenna is a full sized quarter wave elevated ground plane made from Rohn 45 with insulated broadcast section at the feed point, which is 27 feet above ground. There are 7, full sized radial suspended at 27 feet, drooping to 15 feet at the ends. My QTH is on a high ridge, more than 300 feet above average terrain for 30 miles in each direction. Electrical noise level is low and I don't use receive antennas. I guess the old saying from real estate is applicable... location, location, location. The antenna is the key factor, but the radio is incredible. 73, Dave, K4TO On Sat, Sep 15, 2018 at 2:00 AM Frederick Dwight wrote: > I have been a ham for 64 years and continue to be surprised.

It all started with the CQ WW CW DX Contest in November, 1979. I decided to do 15 meter single band entry with my basic 4 element monobander at 70 feet, a Drake TR-7 and a kw. The band started off as usual, open to JA, a few SA and Carib stations. I had expected 15 to go dark by 01z but to my surprise it was still going. The log was slowly filling with JA, SA and Carib but now there started to appear goodies such as HL9, UA0, VK, ZL and some other Pacific station. So it sent, hour by hour with no let up in sight. By 08z the opening shifted and now there were eastern EU stations coming through! Yeah -- wow. By 09z the opening to EU closed and I thought I might get a little sleep but first I checked long path. I swung the beam to 220 degrees, the band noise came up and my tuning produced some amazing stuff -- a VK6 (who asked for my zone 3 times -- he couldn't believe it), 9V1 and a host of goodies from SE Asia and even stretching into UL7. Even a EU or two snuck through. By 10z the path closed but lo and behold 15 was now waking up as it normally would with Carib stations and ZS. Within a short time, it was open to EU and it was off to the races. I had never experienced anything like this before or since. Truly an amazing 30 hours because the band didn't actually close until 03z the next night. As for results, 1173 QSOs, 95 countries and 37 zones. Number 5 in the world, top US and a USA record score.

During a recent bout of paper log archaeology, I rediscovered a QSO I logged as a teen, in 1972. I was just minding my own business, tuning up using a Heath DX-20 driving 3 feet of coax to a 40 W incandescent bulb. Then a guy in Illinois called me.... Some years later I was using a home-brew rig (the ?Safari 4?) while visiting my Mom in Arizona. The battery was nearly depleted, the rig putting out only 200 mW. The antenna: 8 feet of wire running directly from the rig through a window to a clothesline. Tuning slowly, I heard a CQ from Rwanda (9X5). I called him and got a ?QRZ?? With a *lot* of patience on his end, we completed a basic QSO. No computer, no narrow filtering, no noise blanker. I would?ve gone nuts for a KX2 back in those days. 73, Wayne N6KR ---- http://www.elecraft.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at 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 w1rm at comcast.net From wa8jxm at gmail.com Sat Sep 15 12:42:52 2018 From: wa8jxm at gmail.com (Ken) Date: Sat, 15 Sep 2018 12:42:52 -0400 Subject: [Elecraft] Craziest / most rewarding QSOs In-Reply-To: <000701d44d04$1e289110$5a79b330$@comcast.net> References: <000701d44d04$1e289110$5a79b330$@comcast.net> Message-ID: The one that comes to mind was via OSCAR III in 1970.?

(my call is N7CQR). So naturally I responded because it?s unusual to work anyone with your same suffix. It turned out that not only was he in my town, but that we were friends from many years past when we played music together (old time string music-?pre bluegrass?) At the time we were playing somehow the subject of ham radio never came up! Moral is always talk about your hobbies! On a more current note-I was reading a previous post where one of the folks was commenting on the high noise levels we experience today. A remedy of sorts is to escape the urban area if possible. Today was the HF campout (we do this every summer) for our local ARES group up in the Mt.Hood Nat?l forest of Oregon-near Timothy Lake if anyone knows where that is. I took the KX2 and a loop antenna (W4OP)about 6 feet high, which I use extensively on SOTA and other outings. Lightweight and goes up in about 3 minutes. Anyway, I set it up and a crowd gathered and someone commented that it didn?t seem to be working as there was no band noise (20M),and another ?the bands are dead'. I sat down,put out a CQ and in 5 minutes worked a slew of stations from Minnesota,Arizona, and other locations around the country. 5 W to a small antenna. Yes-there was almost no noise-just signals. Try it if you can?I?ve been licensed since 1966 and having more fun than ever and getting in shape hiking the SOTA summits.

This is also a symptom of dirty or failing relay contacts, and of junk coax connectors and adapters. And of poorly installed connectors, and of connectors that are not wrench tight. Definition of junk coax connectors and adapters -- they don't have Amphenol or a MIL-spec number stamped into them. If you bought new connectors or adapters at a hamfest or flea market, they're almost certainly junk. All connectors are not created equal -- if, for example, the female center is larger than the male center, they may not make good contact. This is a common problem with junk connectors of all sorts, not only coax. F-type are an exception to that branding -- Snap N Seal is one of the good brands. 73, Jim K9YC From wes_n7ws at triconet.org Sun Sep 16 14:44:29 2018 From: wes_n7ws at triconet.org (Wes Stewart) Date: Sun, 16 Sep 2018 11:44:29 -0700 Subject: [Elecraft] Craziest / most rewarding QSOs In-Reply-To: <700B8B09-7190-4A5E-B715-2C9F536719C0@sy-edm.com> References: <1436e87d-e768-ae8d-59c1-46823279731f@cis-broadband.com> <700B8B09-7190-4A5E-B715-2C9F536719C0@sy-edm.com> Message-ID: This is a support group.?

There is still a lot of mystery and mystic in propagation and sunspot prediction, but a lot of antenna theory of the 1960's has been hardened in science. The foundation of electromagnetic radiation is soundly grounded in Maxwell's Equations - but they are a difficult study all in themselves. I give a lot of credit to LB Cebik W4RNL (SK) for his modeling skills and studies into antennas of various types. 73, Don W3FPR On 9/16/2018 6:57 PM, donovanf at starpower.net wrote: > Hi Bob, > > > You and W4MLE (SK) are both correct about antenna and propagation > theory, based on the universally accepted definition used in science and > engineering: > > > Theory: a well-substantiated explanation of some aspect of the natural > world, based on a body of facts that have been repeatedly confirmed > through observation and experiment. > From cliff at cliffclark.net Sun Sep 16 20:05:56 2018 From: cliff at cliffclark.net (Cliff Clark) Date: Mon, 17 Sep 2018 00:05:56 +0000 Subject: [Elecraft] CW Transmit Text Decode is off Message-ID: I love my KX2, and I thought I would use the TX only CW code to practice, but I'm having a problem.

It sounds like your "L" being decoded as ED is a result of a slight pause between the leading dit and the following part of the dahs and ending dits. Similarly, "R" coming out as ED is the same problem - a slight pause after the first dit. 73, Don W3FPR On 9/16/2018 8:05 PM, Cliff Clark wrote: > I love my KX2, and I thought I would use the TX only CW code to practice, > but I'm having a problem. > > I turn Vox off so there is no RF out. > > I'm sending some letters like L that end up as ED, or something an R ends > up EN.

Look at the entire system and pick out the elements that are common to the affected bands. 73, Don W3FPR On 9/16/2018 2:55 PM, Scott Manthe wrote: > I appreciate the comments and that good RF connectors are important, but > how would a bad connector cause the KX3 to only lose sensitivity on > 30/40 meters? > > 73, > Scott N9AA From rollen at comcast.net Sun Sep 16 20:50:35 2018 From: rollen at comcast.net (Bert Rollen) Date: Mon, 17 Sep 2018 00:50:35 +0000 Subject: [Elecraft] Entertaining Tales In-Reply-To: References: <1223686843.14814568.1537138665255.JavaMail.root@starpower.net> Message-ID: LB was a friend of mine and an amazing guy.

There is still a lot of mystery and mystic in propagation and sunspot prediction, but a lot of antenna theory of the 1960's has been hardened in science. The foundation of electromagnetic radiation is soundly grounded in Maxwell's Equations - but they are a difficult study all in themselves. I give a lot of credit to LB Cebik W4RNL (SK) for his modeling skills and studies into antennas of various types. 73, Don W3FPR On 9/16/2018 6:57 PM, donovanf at starpower.net wrote: > Hi Bob, > > > You and W4MLE (SK) are both correct about antenna and propagation > theory, based on the universally accepted definition used in science > and > engineering: > > > Theory: a well-substantiated explanation of some aspect of the natural > world, based on a body of facts that have been repeatedly confirmed > through observation and experiment. > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at 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 k4ar at comcast.net From cliff at cliffclark.net Sun Sep 16 21:40:35 2018 From: cliff at cliffclark.net (Cliff Clark) Date: Mon, 17 Sep 2018 01:40:35 +0000 Subject: [Elecraft] CW Transmit Text Decode is off In-Reply-To: <6d04b9a2-b141-ecf7-1d55-3afd0cf0b7c2@embarqmail.com> References: <6d04b9a2-b141-ecf7-1d55-3afd0cf0b7c2@embarqmail.com> Message-ID: Well, I think I might know what is going on then.

In other words, principles that have been proven by the scientific method. As a scientist, I have always believed that if you think there's a difference between theory and practice, you don't know enough about one or the other. That is, you don't understand the problem, or you don't understand the known science. Most REAL problems and systems are complex, whether technical or political or financial or business. As Don said, there ARE things that we as a civilization haven't learned yet, and the complex effects of solar radiation are one of those things we know SOMETHING, but not everything, about. On the other hand, there are all sorts of things, everything from science to politics, to interpersonal relationships to how business works that we as individuals have not taken the time to learn, but that ARE clearly understood by those who have taken the time to study them. And the fact that we as individuals haven't yet learned them does not make those things any less true. How antennas and transmission lines work has been clearly understood by those who have taken the time to study them for nearly 100 years. But for someone who hasn't done that, it can seem like black magic. 73, Jim K9YC On 9/16/2018 3:57 PM, donovanf at starpower.net wrote: > Hi Bob, > > > You and W4MLE (SK) are both correct about antenna and propagation > theory, based on the universally accepted definition used in science and > engineering: > > > Theory: a well-substantiated explanation of some aspect of the natural > world, based on a body of facts that have been repeatedly confirmed > through observation and experiment. > > > 73 > Frank > W3LPL > > > ----- Original Message ----- > > From: "Bob DeHaney" > To: elecraft at mailman.qth.net > Sent: Sunday, September 16, 2018 8:21:45 PM > Subject: [Elecraft] Entertaining Tales > > As my Elmer W4MLE told me in about 1961, Antenna and Propagation Theory are just that, theory.

In the telephone industry, especially in the ?good old days? with wire cables, sometimes with many splices it was common to get drop outs. These could be due to a splice, wire wrap connection, oxidized relay contact or whatever, especially with only low level signals. If the circuit also had a DC voltage on it, the problem often did not exist. In fact it was common on critical circuits for the FAA or military, or whatever to sometimes just put ?sealing current? on certain circuits just to be sure it was reliable. Often we used 24 volts DC or less with only a few ma of current. At one time I had many phased verticals which were controlled by many relays. Occasionally the received signal would drop by many S units. Sending a single dot, even with QRP or QRPP power always cleared the problem, sometimes for weeks or months. So it could be a connection in the antenna system, a plug on a circuit board, or even a relay. I have never experienced trouble with Elecraft relays personally. Sometimes PL-259 center pins are not correctly soldered, and can present similar symptoms. You could try a random wire, or even something like an 80 meter dipole on 30 meters, just to see if it was anywhere in the antenna system. Even a volt or two is often enough to punch through a poor solder or oxidized connection, but even something like a 0 dBm signal is just not enough. I have identified problems with BNC connectors and adaptors purchased at ham flea markets which are just not reliable and are probably factory rejects. So look into your antenna system before you dig into your rig. You could also hook a signal generator to the rig and see if it receives OK on all bands with something like less than an S9 signal. Be sure to not transmit into your generator, and/or set your tx to very low power.

Placing a resistor across the telephone line would draw a constant small current, not enough to off-hook the line but enough to "seal" the poor connection, wherever it was, and improve the noise margin. Regarding the PL-259 center pin-- it's also important to check the connection between the threaded shell and the body of the plug. That is a common and overlooked connection point subject to poor connection. Note that there is no electrical connection through the threads on the plug body and the threads on the shell; these threads are merely a stop to keep the shell from sliding down the cable when not connected to the SO-239 on the equipment. The electrical connection occurs through the lip at the back of the shell which butts against the threaded region on the plug. The area of this thin ring of contact is pretty small so it's important that the mating surfaces are entirely clean and free of corrosion. It may help to disconnect the cable, then hold the back of the plug in one hand (where the cable enters it), then pull on the shell with the other hand, toward the pin end, as if trying to pull it off the plug; while maintaining this pressure, twist the shell vigorously. That will help clean the mating surfaces, especially if the plug is not silver plated but that cheap "shiny metal" stuff a lot of plugs have now. Also do this with all jumpers between SWR meter, matchbox, etc. 73, Drew AF2Z On 09/17/18 01:44, Frederick Dwight wrote: > Scott, > The problem you describe is actually quite common in electronics. In the telephone industry, especially in the ?good old days? with wire cables, sometimes with many splices it was common to get drop outs. These could be due to a splice, wire wrap connection, oxidized relay contact or whatever, especially with only low level signals. If the circuit also had a DC voltage on it, the problem often did not exist. In fact it was common on critical circuits for the FAA or military, or whatever to sometimes just put ?sealing current? on certain circuits just to be sure it was reliable. Often we used 24 volts DC or less with only a few ma of current. At one time I had many phased verticals which were controlled by many relays. Occasionally the received signal would drop by many S units. Sending a single dot, even with QRP or QRPP power always cleared the problem, sometimes for weeks or months. So it could be a connection in the antenna system, a plug on a circuit board, or even a relay. I have never experienced trouble with Elecraft relays personally. Sometimes PL-259 center pins are not correctly soldered, and can present similar symptoms. You could try a random wire, or even something like an 80 meter dipole on 30 meters, just to see if it was anywhere in the antenna system. Even a volt or two is often enough to punch through a poor solder or oxidized connection, but even something like a 0 dBm signal is just not enough. I have identified problems with BNC connectors and adaptors purchased at ham flea markets which are just not reliable and are probably factory rejects. So look into your antenna system before you dig into your rig. You could also hook a signal generator to the rig and see if it receives OK on all bands with something like less than an S9 signal. Be sure to not transmit into your generator, and/or set your tx to very low power.

Message-ID: When I saw the "it's just a THEORY" post go by, I sat down and wrote a reply, because it really pushed my buttons. I keep trying to get rid of this pet peeve, but like in Steven King's "Pet Sematary", it keeps finding its way home again. I wrote that reply, but then I deleted it, because I figured I'd just be screaming into the wind yet again, and didn't want to alienate anyone with my pedantic diatribe. Then something odd happened. The next post was pretty much what I had written. A tad SHORTER, but still the same basic idea. Then there was another one. And another. I found that had I posted that original post, it would have found kindred spirits. But I self-censored to avoid "issues". I find that I shouldn't have done that. So I'm going to recreate that post. Lest I go too far afield, here's what I'm responding to, Bob's reminiscence on something his Elmer said: *"As my Elmer W4MLE told me in about 1961, Antenna and Propagation Theory are just that, theory."* There are two common usages of the term "theory": the scientific, and the popular. One is a technical tool describing the collective knowledge of the scientific community regarding an aspect of reality under study. The other is a disparagement of that process and an attempt to belittle the accomplishments, so contrary ideas can supplant those theories. It hinges on the deliberate misunderstanding of the term. A "theory", to a scientist, is a statement regarding how we think the universe works, with regards to a specific phenomenon. It is arrived at by stating a supposition, then creating experiments to test the supposition in an attempt to either prove or disprove it. If it is proven by the experiment, further experiments are designed to refine the evidence, to discover the extent to which this understanding of reality goes, and, if possible, to find flaws with the experimental conclusions. A "theory" is, therefore, the best knowledge we have regarding something, based upon experiment and observations. What it is NOT, is how the POPULAR definition of "theory" would have us believe. In short, the popular definition of "theory" is: *A wild-assed GUESS.* In this definition, if the scientific assertion was actually correct, you'd just call it a FACT. Since you WON'T call it a fact, but call it a theory, you must not be certain of it. It must still be, in your mind, just a GUESS. But that's not the actual definition of a theory. The "wild-assed guess" in that equation is something called a *hypothesis.* That's the assertion you START with, not the conclusion you FINISH with. But the people who say "oh, that's just a *theory*" don't care. They want the theory to go away, so they can assert their own wild-assed guess and claim it to be fact, unopposed by some unfair *theory* thing. They want to declare things to be facts by *consensus,* or by holding a *vote.* Famously, this was the subject of an April Fool's hoax regarding an attempt to declare pi equal to exactly three in Alabama, because of the Biblical dimensions of Solomon's baptismal font ("ten cubits in radius, thirty cubits in circumference, and round in compass"). This was as I said, an April Fool's article, and did not happen. It DID, however, actually happen in INDIANA, House Bill #246, proposed in 1897, and based on the calculations of an amateur mathematician named Edwin J. Goodwin. It did not pass, primarily because Goodwin was a total loon who couldn't do simple math. The concept was even parodied in Robert A. Heinlein's book "Stranger in a Strange Land". But that's how a lot of people want to run modern day science -- by a show of hands, not a show of evidence. But in order to do this, the concept of a theory has to be reduced to something that can be dismissed out of hand. So they replace the meaning of "theory" with the meaning of "hypothesis", and like the quarter the magician made disappear at your sixth birthday, made "hypothesis" disappear. I can't prove it, but I think they just couldn't pronounce "hypothesis" and said "I'll just use 'theory' instead -- hypothesis is just Greek for theory, after all!" So now you have people who will utterly ignore years and decades of experiment and evidence with a wave of a hand and a disparaging "oh, that's just some THEORY! I'm talking about FACT here!" It IS true that there can be a great deal of distance between "theory" and "practice", but that's not a disparagement of the theory, that's a commentary on our ability to make abstracts tangible. This is the fundamental difference between science and engineering. Science defines how the UNIVERSE does something. Engineering defines how PEOPLE do something, which is a whole other kettle of kimchee. Theory isn't something subordinate to fact. It is a realistic view of fact based upon our necessarily-limited ability to understand how the Universe does things. We frequently assert things as fact, only to be smacked in the face with evidence that it ISN'T fact, and never was. For example, the atom is NOT the smallest indivisible particle of matter, no matter how many pulp sci-fi stories said so back in the early 1900's, which goes to show you that the popular belief, no matter how elegant, common-sense, or widely-believed it is, usually turns out NOT to actually be "fact" after all. Lots of people believed the Earth was the center of the Universe, and the sun and planets revolved around it. Heck, there was even this really huge established consensus on it. All the philosophers agreed that the sun revolved around the Earth, and that anyone who said otherwise was just a big FIBBER (and a heretic...burn the heretic!) who should just be quiet and let the consensus win. Yes, antenna theory is just theory...but that doesn't invalidate antenna theory. It might, however, invalidate someone's beliefs or some group's consensus. And just because someone might be bad at using the theory to make a good antenna does not indict the theory. It indicts that person's engineering ability. Nothing more. Just as we shouldn't arrive at scientific conclusions by consensus, we shouldn't invalidate the results of calculation, experiment, and observation with dismissive false dichotomies and popular consensus either. -- -+-+-+-+- Jenny Everywhere's Infinite: Quark Time http://quarktime.net From donwilh at embarqmail.com Mon Sep 17 12:59:00 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 17 Sep 2018 12:59:00 -0400 Subject: [Elecraft] loss of RX sensitivity In-Reply-To: <66be949a-6ebc-8f33-dc01-4f07757f37f1@af2z.net> References: <20180917054706808@smtp687.redcondor.net> <66be949a-6ebc-8f33-dc01-4f07757f37f1@af2z.net> Message-ID: Drew and all, I beg to differ, unless you meant something different than I read.

This is simply not true. The entire PL259 body and shell and the entire mating body are part of the connection. What IS correct is that 1) the connectors must be properly installed both to the coax and the equipment, and 2) that the shell must be well tightened, often described as "wrench tight," with the pins on the PL259 firmly seated in the notches in the mating connector. I'm being generic about mating connectors because it's equally true of SO239 and other connectors like barrels, elbows, tees, and inter-series adapters. 73, Jim K9YC From rmcgraw at blomand.net Mon Sep 17 16:10:28 2018 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Mon, 17 Sep 2018 15:10:28 -0500 Subject: [Elecraft] loss of RX sensitivity In-Reply-To: <23c34601-8c02-e4a7-0cd1-ffa2748fa971@audiosystemsgroup.com> References: <20180917054706808@smtp687.redcondor.net> <66be949a-6ebc-8f33-dc01-4f07757f37f1@af2z.net> <23c34601-8c02-e4a7-0cd1-ffa2748fa971@audiosystemsgroup.com> Message-ID: <83F659CB-3DB1-40C2-AD11-11A6F3D05AE5@blomand.net> Yes, regardless of how good they look, always snug the PL-259 with a small pair of Channel Lock pliers. Finger tight is not good enough. Many of our connectors today are of inferior quality. Also due to the use of jumpers, the flexing and pulling is prone to damage the connection between the coax and connector. Always suspect the jumper and icon doubt, replace it. AND if you find one defective or in question, immediately cut it in two pieces. Thus it won't be used or confused again.

They must be solidly tight for reliable conductivity to the shield of the coax. All contact from the SO239 to the coax shield is by pressure contact. Finger tight may "work", but unless one has very strong fingers, that is not tight enough to assure a good connection. A parallel is putting a locking nut on a screw by using a 2nd nut - often done if you want to use the screw as an axle, like putting the screw through a hinge (think a trailer rear gate). If you put the 2nd nut on the screw with only finger pressure, it will likely back off with slight vibration and twisting nullifying the locking effect. OTOH, if you fasten the two nuts together with a slight twist of the wrenches, the two nuts will not move and will remain locked together. It is not the friction between the 2 nuts that does it, but there is a slight elongation of the screw threads that keeps significant pressure on the two nuts to keep them together. The same principle applies to a PL-259 to SO-239 thread engagement. We may have "gotten away" with only finger tight in the past, but is one possible cause of failure. 73, Don W3FPR On 9/17/2018 5:05 PM, hawley, charles j jr wrote: > I've found that wiggling the body of the plug while tightening the threads makes the pl259 quite tight with the pins firmly seated in the notches.

The pressure is provided only by the tightening of the threaded portion of the PL259. I ask you - just how much resistance can be expected if you just touch two ends of wires together without further positive contact? The "insulating spacer" is any oxidation on either the SO239 or the PL259. That is why I like silver plated UHF connectors. They may look a bit corroded, but the silver oxide is conductive even though it can appear brown or black. If you are shopping for UHF connectors at hamfests, avoid all those nickel-plated ones that a not Amphenol, but flock to those that are oxidized, and silver plated with Mil Spec designations on them. 73, Don W3FPR On 9/17/2018 6:39 PM, ANDY DURBIN wrote: > " the threads of the PL259 are providing the only contact with the SO239" > > > In the connectors that you are mating how do you prevent contact between the end face of the PL259 body and the end face of the SO239 body?

Depending on the location of the two center conductor insulators in the plug and socket, the serrated (toothed) surface of the female connector might well contact the mating plug surface, if there is a gap between the insulators. In fact the "tighten it with pliers" crowd might actually be forcing this connection and mistakenly believing that they are improving the connection via the threads. Wes?

Strain relief is extremely important with BNC connectors. TNC connectors are far superior but not widely used. While professionally installed N connectors have superb RF characteristics, all too often they're improperly installed -- even by professionals -- leading to damaged connectors if the male pin is misaligned, or unreliable contact if the pin or socket depth is just a few millimeters less than the manufacturers specification. I use only captive pin male N connectors, avoiding the most severe problems. I never use female N connectors on cables, the N sockets are much too fragile. Its hard to beat high quality silver plated UHF connectors at HF and 6 meters. But its important to use a tool to tighten them. That's a small price to pay for a very reliable connector. 73 Frank W3LPL ----- Original Message ----- From: "Walter Underwood" To: elecraft at mailman.qth.net Sent: Monday, September 17, 2018 11:45:10 PM Subject: Re: [Elecraft] loss of RX sensitivity The next time someone challenges me on why I only use BNC and Type N connectors, I?m going to send them this entire discussion. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Sep 17, 2018, at 4:41 PM, Don Wilhelm wrote: > > Andy, > > The PL259 to SO239 connector "end face" contact is provided only by pressure - it is not a sliding contact as you would find in a BNC or an N connector.

On receiving FT8 signals, what is the DT time shown for most received signals? Should be less than 1 second and typically less than 0.3 seconds. If so there is nothing wrong with your computer time. Likely the delay is processing time, computer or interface or a TX delay set in the application.

Bob, Take a look at the arrestors that Array Solutions sells, which are the circuit that were built under the ICE name until the owner died a decade or so ago, and that they sold. I'm now using them, and have them mounted in a large Hoffman enclosure. I like the circuit because I believe it is a better solution to the discharge problem, and I like their construction because the GDT is user replaceable. If you lose the GDT in a Polyphaser you throw it away and buy a new one. https://www.arraysolutions.com/surge-and-rf-protection/as-303u 73, Jim K9YC From donanddeena at hotmail.com Tue Sep 18 12:53:25 2018 From: donanddeena at hotmail.com (Don Schroder) Date: Tue, 18 Sep 2018 16:53:25 +0000 Subject: [Elecraft] P3 Panadapter Message-ID: Morning!

Perhaps the most fun I had in HAM radio was building the K2. I learned a lot about soldering and assembly techniques. Electronics technology has advanced with miniaturization and surface mount parts. The skill and equipment requirements for surface mount work is beyond the average amateur. Elecraft does not offer kits that require surface mount work. The assembly process for the K3 is much less satisfying than with the K2. All circuit boards come pre-assembled and you are pretty much just building the box and plugging things in. I also have worked extensively with the P3. I find it very helpful. There is a wealth of knowledge you get from being able to visually see the spectrum you are working. That being said, some of the advantages of the P3 come from its close integration with the K3. I would believe that close integration would not be possible with the K2. There are also other panadapter options including the LP-Pan, which will allow you to view the K2's spectrum. I much prefer the P3 because of the handy controls that allow you to adjust the image, but some of those other options may be less expensive. Think also of where you might go with all this. The K2 is a wonderful rig and more than adequate for HF work. If yuou get really serious about this you may, as I did, choose to upgrade to either the K3s or KX3. The P3 could be used with the K3s but the KX3 has a different, smaller unit. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Don Wilhelm Sent: Tuesday, September 18, 2018 10:13 AM To: Don Schroder ; elecraft at mailman.qth.net Subject: Re: [Elecraft] P3 Panadapter Don, You can use it with the K3 (the P3 input can be tuned anywhere between 455kHz and 21 MHz).

Don, W3FPR, is your go-to guy for all things K2. The P3 is basically a tuneable receiver from just below the AM broadcast band to somewhere around 20 MHz.? It will "work" with the K2 but you have to bring out the IF signal.? I put "work" in quotes because the P3 will integrate with a K3 to give several modes of operation.? One very popular one is "Fixed Tune" where the edges of the display remain fixed and tuning the K3 moves a cursor. With the K2, the only mode available is "Tracking Mode" where the center of the screen is always where you are receiving, and as you tune, the signals on the band all move. As far as general P3 usefulness, for me it is huge.? It's all I look at when I operate.? I operate W7RN remotely on occasion, I really miss the P3, and I hope Elecraft is working on a remote capability for it. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/18/2018 9:53 AM, Don Schroder wrote: > Morning! > > I have a kit K2 s/n 7818 that is about 2/3rds complete.

What is its current selling price? If you use many BNC connectors, you'll notice a distinct difference in connector quality especially above 100 MHz. Avoid using BNC male connectors with weak tension when you turn the bayonette to engage the connector. If the bayonette turns too easily it doesn't maintain sufficient engagement force to keep the RF connections in proper alignment. 73 Frank W3LPL ----- Original Message ----- From: "Wes Stewart" To: elecraft at mailman.qth.net Sent: Tuesday, September 18, 2018 5:51:45 PM Subject: Re: [Elecraft] loss of RX sensitivity It's difficult to argue with Frank's experience and expertise.

When c22 is adjusted to a point where it lowers the frequency of TP1 below 14.915, the display freezes and it stops responding to button presses.

I found that the J310 FETs that came with the kit were slightly too slow to make the synthesizer operate. Apparently this is an issue with the latest batch of J310s. There's a couple of solutions for this: (1) install a 10 pF cap between the source and ground of Q19 or (2) use a different J310. I tried both solutions, they both worked. In the end I elected to source some J310s from kitsandparts.com which were an older vintage, and it worked fine without the extra capacitor. I also found that the trimmer caps for the 10m/12m bandpass filter (C44, C46) were very touchy; I thought for a while that 12 meter TX was not working, but I finally got them tuned up so that I had good output power on 12m.

The frequency readout uses the contents of the EEPROM that are produced when you do the CAL PLL and CAL FIL procedures. The only time C22 must be set correctly is just before you do a CAL PLL or a CAL FIL. At other times it is just a clock for the MCU and does not need to be accurate. I suggest you read the K2 Dial Calibration article on my website www.w3fpr.com and proceed according to those instructions. 73, Don W3FPR On 9/18/2018 9:27 PM, AE0MM via Elecraft wrote: > Just completed assembly of my K2.

Mostly, N connectors, BNC's, TNC's, SC and 7-16's.? And for the big stuff, EIA flange connectors.? Plus some other weird stuff.? (3 lug BNC's and such, to prevent the "wrong connection".)??? The odd appearance of the C connector on some US kit too.?? Some "Spinner" 'BN' series connectors to, also often seen in the European Broadcast industry and some military. A lot of US equipment also still use the various unique to the US connectors, often seen on big Bird loads etc.? Not so common over hear. That based on what I've seen on kit "being tested" at customers sites over the last 28 years. The only UHF series connector commercially used, that I've personally seen in that time frame is on a very old design of screened room weld crack detector, and it's a nightmare to use as it's always working loose. To Charlie. The threads have no part to play in the RF path on a UHF connector, it's all down to the two outer mating faces being pressed together.? The older (so called) MIL spec types, that had all the castelations at that point were *MUCH* better because of it, as they sort of interlocked and made a much better contact due to the metal to metal force multiplication that results..?? They also tended not to rotate relative to each other so the retaining ring stayed tight.? Basic mechanical design feature, missing on the modern versions, where the two parts can rotate, even when the ring is (allegedly) tight. The modern stuff with the 4 slots on the socket, and two bumps on the plug, are just utter crap.? (Built down to a cost.) I'm amazed that no maker has innovated gone back to the original design, and fitted a crinkle spring washer behind the locking ring, so that contact pressure can be maintained, and also helping to keep the threads from working loose when subject to vibration... But even then, they'd still only be of any practical use below 100MHz due to the impedance mismatch issue.?? (Originally for use below 30MHz.) https://en.wikipedia.org/wiki/UHF_connector Stick with BNC's, N's and if you have too, 7-16's.? They are all easy to fit to cable with practice, no special tools needed unless you insist on the crimp types, and then you *MUST* have the correct tooling for that particular make of connector. The pressure gland fitting types, are also easy to remove, clean up and re-fit if a cable becomes damaged. All it takes is some practice.? Buy some surplus ex-military patch leads, and practice removing and refitting them.? After a few of each it becomes very easy. 73. ??? Dave G0WBX.

This is less of a problem with BNC connectors because the coax used is generally has a somewhat flexible shield. > > > > > --- > This email has been checked for viruses by AVG. > https://www.avg.com > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at 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 donovanf at starpower.net > > > ------------------------------ > > Message: 18 > Date: Tue, 18 Sep 2018 10:50:25 -0500 > From: Gene Sochor > To: elecraft at mailman.qth.net > Subject: [Elecraft] K3/100-F Sold, P3F > Message-ID: <201809181550.w8IFoSu1028050 at mail40c28.carrierzone.com> > Content-Type: text/plain; charset="us-ascii"; format=flowed > > K3/100-F s/n 6587 has been sold. > > P3-F s/n 2191 New, unopened in original packing is available for > $500.

CW mode uses a receive offset equal to your sidetone pitch which can cause you to be in error by twice the sidetone pitch. What mode are you using when you tune WWV?? It must be SSB, and you must tune the transmitted tones correctly (do not tune to the carrier).? 500 and 600 Hz tones are sent on alternating minutes except for announcement and silent minutes.? A 1000 Hz tone is sent for 1 second at the beginning of each minute.? Make certain you are hearing the tones at the correct audio frequency. An audio spectrum analyzer running on your computer can be very helpful, or set a receiver capable of receiving in AM mode to tune WWV as well as the K2 and match the audio tones. 73, Don W3FPR On 9/19/2018 9:19 AM, AE0MM wrote: > Don, > > > Where I'm getting stuck is step one under SETTING THE K2 REFERENCE OSCILLATOR on this page: > http://www.w3fpr.com/dial_cal.html > > Then step two on this page: > http://www.w3fpr.com/n6kr_method.htm > > For a 10MHz reference, I'm unable to get the difference between TP1 (VCO) and TP2 (BFO) any closer than 10001.50.

The VFO display reads about 1.5KHz high. I've attempted several times to calibrate it by adjusting C22, but I'm not able to get the frequency of TP1 on the 30m band any lower than ~14.9154MHz (while the vfo set to zero beat with a 10MHz signal) without it causing the radio to stop responding. > > > > When c22 is adjusted to a point where it lowers the frequency of TP1 below 14.915, the display freezes and it stops responding to button presses. If the power is cycled, no relays click and the display has no indication of life. When c22 is returned to the previous setting, the radio becomes responsive.

OpenVPN lets you connect remotely from the outside world and actually get an IP off of your own LAN. The best thing about this is you aren't opening ports that *might* be vulnerable to some exploit -- other than the Pi, but at least it's a single point of attack. You don't have to be a Linux expert to do this, you can pretty much do this in cookbook fashion successfully. Once installed, you also get access to any NAS boxes, your home printer, etc. from anywhere -- the VPN is just like a really long ethernet cable. Eventually, I'll get FLDIGI running on the Pi, when time permits, and have everything I need to run digital from anywhere inside or outside my home. 73 -- Lynn On 9/19/2018 8:30 AM, John Langdon wrote: > I set the IP by using the facility in my router to assign a fixed IP to a MAC address.

Has your XG3 been calibrated for frequency?? It is not a precision frequency standard. The K2 dial frequency is always the frequency of the transmitted carrier (or suppressed carrier for SSB). In CW, the receive frequency is offset by the amount of your sidetone so you hear the signal at your selected sidetone pitch. Make certain you have the filters on the right sideband.? If you have them correct, the DAC values for LSB, RTTY, and CW will be lower than the DAC values for USB, RTTYrev, and CWrev (bar over the "r" or "c"). If you have the wrong sideband, the error will be twice the sidetone pitch. 73, Don W3FPR On 9/19/2018 12:04 PM, AE0MM wrote: > I'm using the XG3.

Easy peasy. I don't want VOX on when I turn my KX2 on just in case I want to go to the SSB portion of the band. Look in the manual to help you with the steps to take. I've also used a PF function for ATU and BYPASS - in that case when I use the AlexLoop, when I don't want to use the auto-tune, a button push takes me away from that. Another function is AF - with my KX3 it's got a separate knob - rather than go into the MENU for that, I've got a PF to take me directly to that as well. I'm going to sell my KX3 - not that I don't like it, but man I'm using this KX2 all the time. I thought I'd miss some of the KX3 features, but that's just not the case for me.

I have a similar setup with an incoming VPN. You can be anywhere in the world with a computer or mobile device and connect to your home network and have access to everything as if you are there. I also use OpenVPN, but on a larger Linux computer. It also can be run on a router with DD-WRT or even on a commercial router designed for this purpose. There are other VPNs also. If you do port forwarding, anyone on the internet can access your KPA1500. As far as I can tell, it is not meant to be connected to the internet. There is no security or password protection. And, someone will figure out how to do bad things. There are just people like that out there. I generally think port forwarding is a BAD IDEA! Many security and baby cameras that use port forwarding have been hacked. There are even automatic search engines to find them. A VPN on the other hand provides pretty good security. The VPN server runs on a computer on your network. A client runs on the remote device. It generally requires something you know (a password) and something you have (a digital certificate on the client ). So, for anyone to get in, they need both your client device and the password. You can revoke a stolen digital certificate and create another if needed. There have been vulnerabilities on VPNs, but they get patched and if you keep updated, you are certainly better off than using port forwarding. There are a couple drawbacks though. Your ISP may block some incoming connections. I also would say that I did successfully set it up, and it has worked for years with no problems, but it was not simple. There are cookbooks to do so, but they are long cookbooks. A commercial router with this capability may be better if you don't feel so inclined.. Good luck in whatever you do. 73, Mark W7MLG On Wed, Sep 19, 2018 at 9:34 AM, Lynn W.

I'm a member of some similar lists. Every time somebody asks for help of some issue, the biggest count of "advices" distrace far away of the original subject. Are U sure that zillions of ways how to tighten A certain connector or wisdoms alike, are any real kinda solution.? Seems that the real fact goes 2far OFF-TOPIC! To unveil, I have caught myself undeliberately pressed the antenna selector swith, being too lazy to read the display. Fortunatelly I havent (yet) dismantled any of my gear to find the real reason. :-D 73 & CU Penna OH2G elecraft-request at mailman.qth.net kirjoitti 18.09.2018 klo 21:45: > Send Elecraft mailing list submissions to > elecraft at mailman.qth.net > > To subscribe or unsubscribe via the World Wide Web, visit > http://mailman.qth.net/mailman/listinfo/elecraft > or, via email, send a message with subject or body 'help' to > elecraft-request at mailman.qth.net > > You can reach the person managing the list at > elecraft-owner at mailman.qth.net > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Elecraft digest..." > > > Today's Topics: > > 1.

Leave DHCP enabled in the PA and any other equipment, but make a written note of the PA's LAN port MAC address.? (And that of any other LAN connected device you have.) In your router (or other DHCP providing gadget) look in it's setup for "address reservation" or similar menu item (or RTFM to find it) In there you can usually identify all currently connected devices, if not by name (if the device reports that) but by MAC address, and you can then tell the router (or whatever) to always assign the same IP address to that MAC address. (If the device is not connected, then that IP address is not assigned to anything else, as it is reserved for that MAC address alone.) In your PC (whatever type) you can also edit the "hosts file" to assign a known IP address to a "name", making things even easier.?? Lot's on the interweb about that.? (On Windows, you will need Admin rights to write to/save that file, on Mac/Linux you'll need Root privileges, so take care.?? Make a pre-edit backup, just in case!) Job done. I (and many others) do this, for such items as NAS servers, dedicated special purpose PC's, printers, other servers, Raspbery Pi's (used as VPN endpoints) IoT and and LAN to Serial port devices. ? It all "just works" seamlessly. But, do keep written notes as to what you did, as you will need that sometime in the future. Hint!? If you don't want to mess with your ISP's supplied router, there is nothing whatsoever preventing you from using something like the old Linksys routers as dedicated "Shack" routers, that you have 100% full control of.? If at some point your ISP changes, nothing in the shack needs to change, as that box is just another device on the new router's LAN side. Many pre-used domestic routers can be used for this sort of thing, and just about all commercial SoHo routers too.? Especially those that can take the WAN side by a network port, not just cable or xDSL. Lastly, I don't know what Elecraft use for their LAN ports, but if they are the common Lantronix embedded devices, then Lantronix have a "device installer" program, that will reach out find and identify the IP address of all such devices on your LAN.? You'll still need to know the device's MAC address though.? Find it on their website. (Google will tell you where.) That's a Windows tool, there are other (somewhat advanced) ways of doing the same from Linux, I have no knowledge of if that can be done with a Mac. 73. Dave G0WBX.

The science behind this is that 1) human hearing is logarithmic, so our ear/brain hears greater difference between signals at lower frequencies (because the same difference in Hz is a greater percentage difference); and 2) most (but not all) hearing loss is greater at higher frequencies. BTW -- for those who don't know, psychoacoustics is the science of how humans perceive sound. It includes speech intelligibility, how we hear music, the effects of noise, echoes, and reverberation, how we perceive directionality of a sound source, and so on. 73, Jim K9YC From d.cutter at ntlworld.com Fri Sep 21 03:22:10 2018 From: d.cutter at ntlworld.com (David Cutter) Date: Fri, 21 Sep 2018 08:22:10 +0100 Subject: [Elecraft] Conditions, shmonditions: DXing anyway In-Reply-To: <86CE3E73-48DC-481C-AE82-72F716B06D2E@elecraft.com> References: <86CE3E73-48DC-481C-AE82-72F716B06D2E@elecraft.com> Message-ID: <011901d4517b$d03ec970$70bc5c50$@ntlworld.com> On a related tack, I am often surprised at how high the radio volume has become in the club shack.

First, if a radio has a relatively low power audio output stage, higher sound levels are more likely to drive it into distortion. Loudspeakers, especially cheaper ones, also distort more at higher power levels.? Second, reverberation and echoes are "noise" as far as speech intelligibility is concerned; while that IS a linear ratio, human hearing is not, so reducing the level may bring those echoes/reverb down to a level where it is less perceived. > It is also significant that a separate loudspeaker on a shelf being more in line with our ears provides significant improvement in our ability to "hear" the station. Exactly right, and that is ENTIRELY the result of 1) loudspeaker directivity -- lows are more omni-directional from nearly all loudspeakers, while the highs becomes increasing directional. [This is due to wavelength of the sounds as compared to the size of the loudspeaker diaphragm.] When we and the loudspeaker are facing each other, we're getting both highs and lows. When the speaker is turned away from you,? we hear the lows but not the highs, AND those highs spray to whatever surface they face, and bounce around to create echoes. 2) The higher speech? frequencies are most responsible for speech intelligibility, lows provide almost none. > Louder is not better. Louder is only one part it. 73, Jim K9YC From indians at xsmail.com Fri Sep 21 06:47:06 2018 From: indians at xsmail.com (Petr, OK1RP/M0SIS) Date: Fri, 21 Sep 2018 03:47:06 -0700 (MST) Subject: [Elecraft] Conditions, shmonditions: DXing anyway In-Reply-To: <86CE3E73-48DC-481C-AE82-72F716B06D2E@elecraft.com> References: <86CE3E73-48DC-481C-AE82-72F716B06D2E@elecraft.com> Message-ID: <1537526826395-0.post@n2.nabble.com> Hi Wayne, thanks for nice example. Definitely agree. I am using the pitch set to 360Hz for long time and it is the best result for myself... after long time testing and experimenting with my K3. The 250Hz roofing with the "filtering on the K3 dialed down to 100-150Hz and 30Hz audio peaking filter (APF) turned on as same as the noise blanker optimized" is the standard setup which I am using for daily operation on CW and it is famous for DX hunting as same as for rag-chews. The only think I have on K3 f/w if it is possible to implement the "automatic fine tuning 1Hz rate" while the APF is on as it is already in KX3.

It would let you turn the slug but you would have to use it with care as it could damage the top of the slug. Also the metal screwdriver can affect the inductance of the inductor and throw off the adjustment. Your safest option is to shave a little off each side of the plastic tuning tool to make it fit. You shouldn't need to shave much off it to make it fit. -- Cheers!

Running alongside a Drake R4C receiver, I've been experimenting with a homebrew CW transmitter over the past month that includes a sidetone oscillator. I adjusted the pitch of the sidetone for something that "sounded about right" to my ears and left it at that. Last weekend I decided to measure the frequency of the sidetone and found it was within 1 Hz of 800! I suppose I've been listening to CW at 800 Hz for so long, I just committed the pitch it to memory. :-) 73 de John, KD2BD From w6fvi at sbcglobal.net Fri Sep 21 13:16:21 2018 From: w6fvi at sbcglobal.net (Brian & Cyndi) Date: Fri, 21 Sep 2018 10:16:21 -0700 Subject: [Elecraft] K3 : Rack Mount Option?

Not likely since the right panel of the K3/K3S and the left panel of the P3 are both mounted with 3D connectors and screws passing from the outside of the panel. In addition, the K3/K3S has regulators which use the right panel as a heat sink and capturing that inside the P3 would impact the cooling ability. 73, ...

Not likely since the right panel of the K3/K3S and the left panel of the P3 are both mounted with 3D connectors and screws passing from the outside of the panel.? In addition, the K3/K3S has regulators which use the right panel as a heat sink and capturing that inside the P3 would impact the cooling ability. 73, ??? ...

The immediate reason to change pitch has usually been a perception that with the existing setting, the best copy pitch does not exactly coincide with the CW tuning indicator (another great CW asset of the K3), or with the peak DSP filter response. Many times this has led me to change the pitch setting by a small amount, whether my general preference du jour is for a low or higher pitch. To make such an adjustment I like to set a wide DSP bandwidth and slowly tune through a received signal. The apparent loudness doesn't stay constant, nor does it follow a smooth variation that I attribute to my own hearing response. Instead I hear peaks within range of piches that would be reasonable for CW, that I attribute to the speaker and its surroundings. (I would say that since I went to the SP3, there is less of this variation, but no matter how good the speaker, there will always be such variations because objects around the speaker cause reflections.

Rather than adjusting the pitch to some value considered ideal based no prior considerations, I set it for a peak in the accoustical response of the particular speaker and its surroundings.

Adjusting the VFO/RIT for a different pitch is not really an option at that point. You're right though, PITCH as implemented is mainly meant to pick your favorite tone and pretty much stick with it; not for trimming up individual signals like you would with AF/RF gain. 73, Drew AF2Z On 09/22/18 07:11, Nr4c wrote: > Come on!!! > > I adjust the ?pitch? to suit my hearing.

It made a noticeable difference for the better in weak signal decoding for CW for me... YMMV. 73s and thanks, Dave (NK7Z/NNR0DC) https://www.nk7z.net ARRL Technical Specialist ARRL Volunteer Examiner ARRL OOC for Oregon On 9/22/18 4:40 AM, Drew AF2Z wrote: > When you've got a weak signal peaked in a narrow filter or APF, that's > the time you'd like to optimize the pitch.

Over time changes are made to a web site software as items are added, subtracted, changed or just messed up by accident. There comes a time when it just makes more sense to just either start from scratch or do a major overhaul and change all around. New things have been added where old things were located or errors have creeped in in unknown places. Or the original author has moved on. You can only make so many changes before you just have to clean things up.

RIGHT! The ONLY good use of ALC between rig and amp is to protect the amp from a failure in the antenna system. To do that, set output power from the rig to get the desired output level. 73, Jim K9YC From n1rj at roadrunner.com Sun Sep 23 16:05:07 2018 From: n1rj at roadrunner.com (Roger D Johnson) Date: Sun, 23 Sep 2018 16:05:07 -0400 Subject: [Elecraft] KPA1500 In-Reply-To: <5b786b90.1c69fb81.199a1.cc24@mx.google.com> References: <0fa540cc-4cca-f107-02e3-ae520202c73d@ac0c.com> <9ead7fd9-b3bb-5e4d-e431-58356e8da222@blomand.net> <5b786b90.1c69fb81.199a1.cc24@mx.google.com> Message-ID: I think I've bricked my KPA1500!

I know this because ALC voltage is included in my logger data set and I have several logger records for Fault 09. (It's not that I'm really careless about antenna switching.

I can pay via PayPal and will cover the fee's. I'm also open to driving a reasonable distance with cash in hand. Please contact me directly via email if you have one up for sale. Thanks!

By definition, 6M is VHF, which is defined as 30-300 MHz. The need TX delay/sequencing is related to relay switching times, NOT operating frequency. The relationship to VHF/UHF has to do with slow relays in equipment like power amps and mast-mounted preamps. 73, Jim K9YC From n0nbd at outlook.com Tue Sep 25 09:46:54 2018 From: n0nbd at outlook.com (Paul Smith) Date: Tue, 25 Sep 2018 13:46:54 +0000 Subject: [Elecraft] My KX2 may be sick Message-ID: Last night after working a couple SKCC guys on 3550 my KX2 just shut down and said on the display err key.

I suggest that you remove all cables from the KX2 except for the antenna and power and see if the message is still present. If it is gone, then plug each cable in until it occurs. When you find the offending cable, test it and repair it. In most cases, there is nothing wrong with the transceiver, but the problem is with external cables. It would not be good to send it to Elecraft for repair only to find a report of No Trouble Found and an invoice for $99 plus shipping. 73, Don W3FPR On 9/25/2018 9:46 AM, Paul Smith wrote: > Last night after working a couple SKCC guys on 3550 my KX2 just shut down and said on the display err key.

For several good reasons, I just sent my K3 to Elecraft for service for the first time ever. Insured, double boxed, expensive Uline 3? plank foam cushion support for the inner carton, etc. Because I insured it for a high value, I was required by UPS to take the carton to the local UPS Customer Service Center, not the UPS store, etc. to obtain a signature. Don?t know if I?d scheduled a pickup that it would have been the same fire drill, but that wasn?t an option for me because of UPS schedules around here. Got to the UPS Center at the airport and was told that I had to UNPACK ALL of the cartons so they could see what was inside and determine that it wasn?t explosives (apparently there was an incident at FedEx back in February). UPS did a sloppy job of retaping everything. Nothing worse than having to cut open carefully packed and sealed containers to prove you?re not just another uni-bomber. I bit my lips and was (mostly) friendly about it. Worse than TSA ? because they don?t have the chemical detection wipes and X-ray machines that TSA has. So it?s a bigger than average hassle.

With UPS, if you go on-line and fill out the information and print the shipping label, you can give it to any UPS driver. If the value is $1000 or more, the driver will have to sign your receipt. Less than $1000, you can drop it off at any shipping center. Yes, the UPS store may want to wrap it for you (and charge for that service), but I have never had anyone ask me to do that. So print your own shipping labels and avoid the hassle - if the declared value is $1000 or above, hand it to a UPS driver, or expect to take it to a UPS distribution center (not a UPS store). With USPS, I have insured items for most any amount up to the maximum of $5000 with no questions other than those normally asked about hazardous contents, etc. 73, Don W3FPR On 9/25/2018 3:52 PM, Grant Youngman wrote: > I don?t know what the other guys do.

However USPS doesn't pack. The point being, if I use the Fed-X packing service and it gets damaged or lost it is 100% their issue. In other words they don't come back to me and say "poorly packed". I lost a radio via UPS due to damage. When I recovered it there was a corner crushed and some type of equipment track on the box. Their response was "improper packaging". ????

At power levels greater than 8.0 watts, the K2 was displaying the high current warning. The KAT2 power calibration was calibrated by measuring voltage with the K2's RF probe at the feed point to a dummy load. I removed the KAT2 and remeasured the power across all bands. Again, power was calculated based on DC voltage from RF probe at dummy load feed point. The impedance of the feedline and dummy load were retested. (49 to 51 ohms over the amateur radio bands, measured with a sark-110 calibrated using a set of reference loads) Here are the results: Band Power At Load K2 Current 80 9.7 2.2 40 9.2 2.0 30 9.4 2.1 20 9.7 2.1 17 11 2.1 15 9.3 2.0 12 9.4 2.2 10 9.6 2.3 After remeasuring power, the KAT2 was reinstalled, and its power meter verified correct at 5 watts. With the KAT2 reinstalled, rechecked K2 current draw at 10 watts on all bands. For each band it measured 20% to 30% higher than without the KAT2. With the power level on the K2 set to one watt and the ATU set to CALP, I used the RF probe to measure a few points on the KAT2 control board, and the input from the RF board. At the one watt level, there is approximately 1v drop between K17 pins 2/9 and 4/7. K17 Pins Volts 2/9 9.9 3/8 9.9 4/7 8.6 K18 Pins Volts 3/8 8.6 Is this expected behavior, or is something amiss with this KAT2?

If it drops more than 1 volt suspect your power supply or the power cable. A low supply voltage can cause the K2 to report HI Cur - the K2 tries to maintain the power requested, and a lower voltage requires greater current. Note that at least 2 watts is required to calibrate the KAT2 wattmeter and to do a TUNE. The first step in bringing up the KAT2 is to balance (null) the wattmeter. Adjust the trimmer capacitor for the lowest reading in ATU menu CALn. After that, connect a good 50 ohm dummy load and do the CALP setting. Use an external wattmeter that you trust, or the measurement of the RF voltage with the RF Probe will work, but requires some calculation in between adjustments. The external wattmeter is quicker. With the ATU menu set for CALP, the relays should be set to open all paths to the capacitors and to short out the inductors, so I doubt that those relay measurements are of value - unless one of the relays has an unsoldered pin 1 or pin 10 which will not allow it to switch. Check the schematic to see which relay pins should be closed and which should be open. 73, Don W3FPR On 9/25/2018 5:35 PM, AE0MM via Elecraft wrote: > Just installed the KAT2 in a newly assembled K2.

In the September VHF contest, the first time I've used that band on that radio, I found that the transmitter is flying. It puts out 2-3 watts when keyed, regardless of mode (CW, SSB), with no keying/modulation. It drives up to a few watts output and sounds okay on-frequency, TX and RX, but is clearly not stable and the bad energy is in-band on 2 meters, and quite nearby. I haven't looked at the output on the spectrum analyzer yet, or taken the radio apart to inspect the transverter; I wanted to ask here for any similar experiences before I tear into it to hopefully save a bit of time.

No way am I trusting them with a high value package. I hate and dread it when I order something and it starts out UPS or FedEx and ends up "smart posting" through USPS the last mile. The few times I've tried to file a complaint (via phone or face to face) all I got was a run around and a carrier lying to my face. YMMV.

The UPS driver clearly thought we wouldn't be home for some reason -- perhaps too cynical? I don't know -- so he didn't bother to carry it the 14 lb box to the house. Maybe he didn't want to have to carry it back to the van in the rain? An interesting speculation, except for one small detail. I was home. So was my partner. We were sitting 6 feet from the door, and if the driver had even set foot on the porch, we would have noticed him because we were sitting by a window onto the porch. Instead, he brought a small Amazon package to the porch, to which he affixed the "sorry, we missed you" tag, and tossed them onto the porch and ran back to his van. In earlier times, they simply would have brought the package back the next day, but not these days. He took the package to a pickup spot, a UPS store about 5 miles from my house, and I had to pick it up the next day, in person, with my ID so I could sign for it. The sheer laziness of this event stunned me. He just didn't seem to want to carry the box to the door in the rain, and was willing to inconvenience the recipient of an expensive package just to avoid a couple minutes' work. I don't have this trouble with FedEx, though I sometimes have problems with Amazon drivers who claim not only that they delivered my package, but put it directly into my hands, when I didn't even receive it until 2 days later. They simply lie to avoid doing their jobs. It's the only thing I can think of to explain it. It doesn't do any good to complain. I raised the roof at UPS, and it had zero effect. The woman on the phone told me she'd have the package brought back to my door. Instead, it went to the pickup spot and I had to get my disabled butt to their store to pick it up. Very frustrating!

If it is not correct, you have a problem with the thermistor board - most likely a solder bridge. You should have 8 volts at the thermistor board pin 8. If that is not correct, look carefully for solder bridges. That 8 volts comes directly from the 8 volt regulator voltage rail. It does sound like you have a problem with the PLL Reference Oscillator, but your voltage measurements on the thermistor board pins should be investigated first before drawing any other conclusions. Make sure you have good results with the PLL range tests just after that. The exact frequency of the 4 MHz Oscillator is not critical at this point - for now it only substantiates that the oscillator is working. If you put a probe on C22, it will pull the frequency. If your frequency counter is sufficiently accurate, wait until you have a good frequency at TP1, and then measure the frequency with both the counter and the internal counter probe using CAL FCTR. Adjust C22 so CAL FCTR frequency is the same as your external counter. I do not know the accuracy of your counter, but mine is accurate to 10 exp-9 and I can set C22 with it for good K2 Dial Calibration. There are other methods for setting C22 that do not depend on the accuracy of your frequency counter. When you can receive WWV at 10 or better 15 MHz, look at my website www.w3fpr.com article on K2 Dial Calibration to accurately set C22 and achieve good K2 dial calibration. 73, Don W3FPR On 9/26/2018 8:14 PM, Don Schroder wrote: > Hi folks, > > Got to the subject location on my K2 kit #7818, and am having some difficulties with the tests.

It turns out that early versions had screw heads that were a bit too long that stuck out the back side of the paddle housing, causing a short to the chassis, if the heads bit through the black paint. I have one of these, and it worked fine until the screw head on one side managed to work itself through the paint, then suddenly I was getting ERR KEY on power up. Elecraft service has shorter screws to fix the issue. I just put a small patch of black tape on the bare metal chip location under the paddle housing, and all is OK. Some day I may ask for the modified screws (or paddle, if it has to be replaced as a unit). Fixing the chip in the black housing is another matter entirely.

If it is not correct, you have a problem with the thermistor board - most likely a solder bridge. You should have 8 volts at the thermistor board pin 8. If that is not correct, look carefully for solder bridges. That 8 volts comes directly from the 8 volt regulator voltage rail. It does sound like you have a problem with the PLL Reference Oscillator, but your voltage measurements on the thermistor board pins should be investigated first before drawing any other conclusions. Make sure you have good results with the PLL range tests just after that. The exact frequency of the 4 MHz Oscillator is not critical at this point - for now it only substantiates that the oscillator is working. If you put a probe on C22, it will pull the frequency. If your frequency counter is sufficiently accurate, wait until you have a good frequency at TP1, and then measure the frequency with both the counter and the internal counter probe using CAL FCTR. Adjust C22 so CAL FCTR frequency is the same as your external counter. I do not know the accuracy of your counter, but mine is accurate to 10 exp-9 and I can set C22 with it for good K2 Dial Calibration. There are other methods for setting C22 that do not depend on the accuracy of your frequency counter. When you can receive WWV at 10 or better 15 MHz, look at my website www.w3fpr.com article on K2 Dial Calibration to accurately set C22 and achieve good K2 dial calibration. 73, Don W3FPR On 9/26/2018 8:14 PM, Don Schroder wrote: > Hi folks, > > Got to the subject location on my K2 kit #7818, and am having some difficulties with the tests.

TP1 reads a solid 4918.88, TP2 reads between flickering 267 & 289, TP3 reads all zeros. The resistance from the source of Q19 to ground is 280 ohms. I did make an interesting discovery when I took voltages again. U4, pin 5 (SDO) is 0 volts, pin 7 (SCK) is 4.8 volts. U5, pin 1 (SCK) is 4.8 volts, pin 2 (SDO) is 0 volts. These pins are just opposite what they should be (what does SDO and SCK represent?). Looks like something that is directional got switched?

The VFO TP1 is apparently oscillating if you have a frequency of 4918.88, but that frequency is not correct. Tackle the PLL Reference first. OK, the PLL Reference Oscillator is not oscillating for one reason or another.? Chek all the components in the circuit for proper values and good soldering.? You apparently can follow the schematic, if for no other reason than to identify components in a circuit - that is helpful information. Make certain D18 is installed with the proper orientation, and that C84 and C85 are 120pF (marked 121). 73, Don W3FPR On 9/27/2018 8:07 PM, Don Schroder wrote: > > Don, > > All three test points are not zeros.

But I have had a problem remembering which KPod buttons perform which functions. Cheat sheets just seemed to get in the way or get lost so I wondered what I could do to make my KPod more user friendly. I made the following modification to my KPod to put the name of each used function directly beside the buttons so I could quickly find what I wanted to do, and made it very easy to change the function names as I reconfigured the device. The links below show a couple of views of what I did. Basically, using some double sided pc board I fashioned a couple of "wings" that I eventually attached to the existing device using the screws that help hold it together at its top face. After shaping and drilling the pieces, I soldered the pieces together to form each "wing", spray-painted them, glued into each top face on each "wing" two small rare-earth magnets. Then I made two plastic cover plates the same size as the top faces, drilled and mounted two more of the magnets taking care to get the poles correct with the lower ones in the wings. Then I typed up a couple of label sheets, placed them on the top faces of the wings, and placed the plastic covers over them to finish the project. It makes a very neat way to easily locate and reconfigure the KPod functions. If anyone has more interest in this I have several more pictures of the way I did mine but I'm sure this idea could be fashioned in many ways from other material you may have at hand. https://www.dropbox.com/s/at0urhx9vehxzxr/IMG_5813.JPG?dl=0 https://www.dropbox.com/s/5o8w7rqagtcipn2/IMG_5811.JPG?dl=0 73, Ken, NU4I From hans.elfelt at me.com Fri Sep 28 16:40:46 2018 From: hans.elfelt at me.com (Hans Bonnesen) Date: Fri, 28 Sep 2018 22:40:46 +0200 Subject: [Elecraft] K2-100 ATU Message-ID: <61CECEAE-4583-4FE6-A82A-176439D5590F@me.com> Hello Elecraft, After a couple of years of flawless operation my K2-100 ( separate units) is starting to act up.: A) At first I noticed that when pushing the ?tune? key, that ATU of the 100 watts unit caused the relays to clatter in the normal way but after finding the 1:1 setting, the tuning condition was not concluded, and I had to switch off the set completely and start anew. Mostly it went well and the tune condition stopped automatically, as it should. BUT B) To-day pushing the ?tune? key did not cause the built-in ATU of the 100 watts unit to start its clattering. The SWR reading ( lights) went all the way to the right, and stayed there. Naturally I switched off the set instantly , while in a split second I noticed the ?Hi-current ? displayed. Using the Ant 2. position going to a 1000 watt dummy-load did not change the malady.. ++++ Disconnecting the 100 watt unit completely, I set up the K2 in its barefoot condition. The built-in ATU of the K2 worked completely normal. ++++ Conclusion: Presumably something has developed in the SWR circuits of the 100 watt unit.

One quick way to check the KPA100 is to remove the KAT100 and connect only the KPA100 ANT jack to an external wattmeter and also a dummy load. Then do a TUNE and see how much power is actually being developed. Set the power to 50 watts. If it is 20 to 25 watts, the KPA100 wattmeter is working properly. But if it is 120 watts or more, diodes D16 and D17 in the KPA100 need to be replaced. They are 1N5711 type. You may also want to arbitrarily replace D1 and D2 in the KAT100 - they are the same type. So if you have to order them, order quantity 4. The most common cause of those diode failures is a static surge on the antenna feedline - likely from nearby lightning. The other cause of that kind of SWR indications is a failure of ATU firmware Pin 3 or 4 or both. That IC can also be damaged by static surges. The HiCur message is also associated with the failure of the KPA100 wattmeter diodes, because that is where the power is controlled from, and the K2 MCU does not know that any power is being developed, and pushes the drive power to the maximum. That also stresses the base K2 PA transistors and if not caught in short order, will cause their failure. 73, Don W3FPR On 9/28/2018 4:40 PM, Hans Bonnesen via Elecraft wrote: > Hello Elecraft, > > After a couple of years of flawless operation my K2-100 ( separate units) is starting to act up.: > > A) At first I noticed that when pushing the ?tune? key, that ATU of the 100 watts unit caused the relays to clatter in the normal way > but after finding the 1:1 setting, the tuning condition was not concluded, and I had to switch off the set completely and start anew. > Mostly it went well and the tune condition stopped automatically, as it should. > > BUT > > B) To-day pushing the ?tune? key did not cause the built-in ATU of the 100 watts unit to start its clattering. > The SWR reading ( lights) went all the way to the right, and stayed there. > Naturally I switched off the set instantly , while in a split second I noticed the ?Hi-current ? displayed. > Using the Ant 2. position going to a 1000 watt dummy-load did not change the malady.

D18 is oriented properly, and it looks like C84 & C85 are marked 121 (kind of hard to read since they are installed). So I thought I would check voltages for the PLL Reference Oscillator circuit. Didn?t take long to find 7.5 volts going into X1 (the crystal) and 0 volts coming out! I resoldered the pins to ensure no cold joints, and still 0 volts coming out. Do crystals go bad, or is it possible I burned it up by too much heat on the casing when grounding it? I think I will need a new one before I can check the BFO. Thanks!

The VFO TP1 is apparently oscillating if you have a frequency of 4918.88, but that frequency is not correct. Tackle the PLL Reference first. OK, the PLL Reference Oscillator is not oscillating for one reason or another. Chek all the components in the circuit for proper values and good soldering. You apparently can follow the schematic, if for no other reason than to identify components in a circuit - that is helpful information. Make certain D18 is installed with the proper orientation, and that C84 and C85 are 120pF (marked 121). 73, Don W3FPR On 9/27/2018 8:07 PM, Don Schroder wrote: > > Don, > > All three test points are not zeros.

That is not the problem. If you want to verify that it is that path, read it while rotating the VFO through a 10 or 12 kHz range.? It should vary.

That is not the problem. VFO through a 10 or 12 kHz range. It should vary. When the crystal oscillates, you should obtain a frequency at TP3. That is your next challenge.

It's a complete package with options for scheduled full backup, incremental backups, continuous backup, disk image, etc. Also can be used to clone disks. Acronis is a very popular backup package for Windows. I used to use it but had several mishaps, including not being able to read old backups. Haven't tried it in a long time. I have EaseUS setup to do a full backup on each disk in my system on the first day of the month, and incremental backups on each disk once a day. The backups are written to a hard drive in a USB dock. I have a set of five of these disks and rotate to the next drive after the last incremental backup of the month. Whenever I visit my safe deposit box, I put one of the disks in the box and retrieve the one that I put in the box last time. That way, I have an offsite backup in case of disaster. It might be a little old, but better than nothing. Further, I have Windows 10 on and SSD and all of my critical data on a separate SSD, including work files, spreadsheets, Quicken data, all my ham radio data (e.g., contest logs), and so forth. This data is continuously copied to the cloud and synced with all my devices so that I have multiple copies of it, including the versions in the hard drive backup rotation. There are many cloud services that can be used for this, but I use Microsoft OneDrive because I get 1 TB of storage free with my subscription to Office 365. It helps to have very high speed internet with fast upload speed (75/15 here, but usually it's more like 90/20.) When apps allow it, I configure them to keep user-specific data on my user data drive. I also try to get them to save their configuration data to my data drive. Unfortunately, some apps don't let you change their data and/or configuration locations. These days it's often in C:\Users\\AppData. I have to be content with that data being backed up to local hard drives only. I've also configured Windows to do a scheduled System Restore Point each day, but it doesn't always work. Typically it's done when updates are applied and sometimes when apps are installed. When I remember, I do one manually. These restore points can be crucial if your system gets messed up by a hardware failure or problem with a Windows update. As you can tell, I'm a proponent of belt-and-suspenders backups. I've been burned many times, going back as far as 1972. First casualty was a term paper, back when most college students used typewriters and virtually no one would have tried to type a paper into a computer. The professor didn't believe me when I told him that a poor design in the syntax of the user interface caused me to accidentally erase the paper. He looked at me like I'd told him my dog ate my homework. 73, Dick WC1M -----Original Message----- From: John Saxon Sent: Friday, September 28, 2018 9:05 PM To: Elecraft Reflector Subject: [Elecraft] OT - backup software I am not happy with my current backup software package.
