The KX3 and K3 threshold and slope numbers may not match, but can be a guide for obtaining the settings that are best for your type of operation.

Small speaker aside, it should sound every bit as good as the analog K2, just with additional filtering features (thanks to the KX3?s DSP). Try turning AGC off. If there really were pumping, this would stop it. If it doesn?t stop, there?s something else going on. Do you have NB or NR turned on? Also try setting RX SHFT to 8.0 to see if you have noise getting into the KX3?s power supply lead. Baseband (RX SHFT=0) would be more affected by this in some cases. 73, Wayne N6KR > On Nov 1, 2017, at 7:17 PM, Ignacy wrote: > > I am going to sell my K2 as it is gathering dust since KX3 came on board.

When he transmits through the Amp, his signal is clean on his frequency, but one can hear the transmission as crackling noise below and above his frequency, even with low driving power. Thats the best i can describe it. We sure want to find out how to prevent this. This has been a topic a while ago on this list, but i can't find it. So is there a recipe for a K3 working together with a Expert 1k? To ALC or Not to ALC? Max. Power IN? Any settings in the K3? Any settings in the amp we overlooked?

If you had only one, contact Elecraft support to get the other two. With the new encoder, you must flush cut (yes right down into the solder) not only the leads on the encoder board, but also the Control Board in the area where the encoder board could make contact. It may also be a good idea to add an insulating material like fish paper or a piece of plastic between the two boards. 73, Don W3FPR On 11/2/2017 6:35 AM, Martin Sole wrote: > I'm in the finishing straight for the build of my nice shiny new K2, > it's been great fun and I'm looking forward to using it soon. > > The new vfo encoder shaft does seem to be a bit too long, either that or > the hole drilled in the knob is not sufficiently deep enough.

I also own a K2 full optional and i think is the best radio for CW, the K2 have the best signal/noise ratio i ever heard and the sound is smooth and natural, very pleasant. I have also a K3s, i love Elecraft rigs, but to me, the more fascinating one remain the K2. I am strong Elecrafter here in Italy, Eric knows this ;-) I prefer the KX3 outside the shack, is complete and can do everything, from phone to cw to digital. The K2 have only SSB and CW. Althoug in CW is the better, in SSB maybe not. I agree with you that "strangely" the audio from the K2 is nicer despite the tight filter, but i still find difficult to push out ALL the watt in SSB. Comparing the K2 to my other radios, included the K3s, i can see that the K2 never reach the maximum output power in SSB. I tried different microphone and settings, but i always get no more than 60-70% of the maximum power in the best conditions. This is the only point of regret with my beloved K2. Is not very important because i mostly do CW and in CW the K2 is a top performer, but i would like to find a solutions before of after. I can also add that i already done all the adjustent suggested for filters tuning and BFO alignments, Gary (from Elecraft) knows how much time we spent on it ;-) Best regards, to all, Graziano IW2NOY (W2NOY) > Il 2 novembre 2017 alle 3.17 Ignacy ha scritto: > > > I am going to sell my K2 as it is gathering dust since KX3 came on board.

If an external wattmeter, you are likely driving it to full PEP power. I test the SSB operation on each K2 I repair to be certain the PEP is the same as the CW response at full power. I use an oscilloscope to determine that. An external wattmeter will only show about 50 to 60% of the full PEP. Run the SSB C menu parameter to 3:1 and try it. If you are using an electret microphone (Elecraft or Icom), the SSB A parameter at 1 should be sufficient, but if using a dynamic microphone, a setting of 2 is good for the higher output microphones but 3 may be needed for those with low output. 73, Don W3FPR On 11/2/2017 7:24 AM, Graziano Roccon wrote: > The K2 have only SSB and CW. > Althoug in CW is the better, in SSB maybe not. > > I agree with you that "strangely" the audio from the K2 is nicer despite the tight filter, but i still find difficult to push out ALL the watt in SSB. > Comparing the K2 to my other radios, included the K3s, i can see that the K2 never reach the maximum output power in SSB.

To further simplify its block diagram the signal path is like this: TRANSCEIVER (external) --> AMPLIFIER --> INTERNAL SWR BRIDGE --> ATU --> ANTENNA SYSTEM (external) The SWR briege in the KPA1500 will report the SWR the amplifier "sees" going into the ATU. As you know, the point of the ATU is to ensure the amplifier itself is feeding a 52 ohm non-reactive load which is expressed as an SWR in the link between the amp and the ATU. I doubt if you'll find a way to 'break in' to the link since the SWR and Power output from the amplifier itself is already a part of the basic measurements that is reported by the KPA1500. You are quite right that putting a coupler at the Antenna output of the KPA1500 (and so the output of the built in ATU) will simply report the SWR the antenna system (including feeder) presents to the KPA1500. Of course if the ATU is in Bypass the internal SWR measurement will show that of the antenna system since the ATU is no longer in the circuit. That only occurs when the SWR presented by the antenna system is low enough to feed directly. 73, Ron AC7AC -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of James Wilson Sent: Thursday, November 2, 2017 10:54 AM To: Elecraft Subject: [Elecraft] KPA1500 with P3 Transmit Monitor Looking at a draft of the KPA1500 amplifier, it appears that the only place to install a TxMon or Wattmeter coupler is at the - output - of the built-in tuner.

I cannot comment on the crackling noise, but on the ALC question, the answer is NO ALC. Although you might want to connect the ALC cable so the amplifier can shut down the driving transceiver in case of an amplifier fault, set the power level in the K3 so that no ALC is developed in normal operation. Using the amplifier's ALC to control the drive from the transceiver is a recipe for overload and distortion - no matter what claims to the contrary might be made by the amplifier manufacturer. The K3/K3S has a menu setting - PWR SET - that allows the power to be set per band which can be useful when driving an amplifier. See the menu listing on page 58 of the K3 manual and also see the manual External ALC setup and Per-Band Power Control on page 27. That may or may not get rid of the noise, but is the proper way to drive an amplifier (any amplifier). 73, Don W3FPR On 11/2/2017 5:42 AM, Martin wrote: > > So is there a recipe for a K3 working together with a Expert 1k? > To ALC or Not to ALC?

Whether Elecraft wants to implement your desire for lifetime forward compatibility of all existing products with all future products is a decision for the company, not us. Frankly, I think that would be financially unwise and a severe limitation on engineering and innovation. If YOU want to use your TXMON features on YOUR KPA1500, here is how you do it... Bypass the KPA1500's internal tuner.? Add your OWN external tuner between the antenna and the KPA1500....? Insert your TXMON module between the tuner and the amp....? (or any other place you may care to insert it). This is the path I am choosing to take, as I will always have horizontal loop(s) that I want to use on multiple bands and frequently need better than a 3:1 tuner. When Wayne asked the pre-launch question, "What features...", I specifically asked for NO on-board tuner knowing I would never use it. I'd MUCH prefer an external KAT-1500 that can tune full power to 10:1.... cost be d$%^d.? :) Alternatively, you could perhaps figure out where to tap the signal path and pull it external to put your module inline... or simply trust the numbers being computed by the device itself. Cleanest idea for no external tuner would be to add the SWR/power readings to Win4K3Suite... Just my 2/100ths of a US Dollar... 73, Clay Autery On 11/2/2017 5:59 PM, James Wilson wrote: > I realize that, Bill but, Elecraft also makes a monitor accessory > for the P3.

I measured the power output meny times with two different meters, one with PEP function and one without. In both cases i can see the differences between the K2 and the other radios. On the same meter where i read 60-70 watts with the K2, i can read 90-100 watt with the K3s. I know that can be an average reading but in any case with the K2 is always lower by at minimum a 30%. This is not so important, i use the K2 in CW where is a top performer and where i think is the best radio for that mode. I was just asking to myself how get the maximum power, so i don't need to change radio when i see a new one in SSB on the cluster ;-) I am quite sure that on a very strong SSB pile up, i will never pass with the K2. Instead, in CW i always do all i can hear and sometimes the K2 hear signals that other radios loose in the noise. My best regards, Graziano IW2NOY PS I read with many interest your article on AGC Settings for K3 on your site.

I need 3 new cases i know i can order them and contact are running and very very promising, but the best thing i can do is just get some old not working K2 K3 P3 stuff. Lighting, reverse polarity i don't mint i want the cases.. and perhaps some parts. Is there some body on this planet who can help me :-)) I live in Holland (the Netherlands) and off course will pay for the units. So please let me know . i rather keep this off list because this is going to generate lots and lots off traffic all those people with old stuff :-)) My mail address is pe1bsb at zendamateur.nu.

I went with the ACC port for now. It is all working fine after a mini debacle described below: At first plugging in my newly made cable from the diagram on the ACOM website, I only got "CAT error" on the ACOM 600s. Checked all my settings, all good. Double checked my cable; all correct to the ACOM provided diagram. Then I checked my cable with the K3 manual and found that I had BAND2 OUT on pin 10 on the K3 side while the K3 manual says pin 9 is the one to use. Double checked the ACOM diagram and it depicts pin 10. Read the text on the ACOM diagram and it says to use pin 9. Switched to pin 9 and all works correctly. Sent an email to ACOM to let them know about the error. Note that ACOM support has been excellent. Below is the diagram V1.2 from the ACOM 600s download page on the ACOM website. Note the text for BAND2 OUT is correct for the K3 side with pin 9; the diagram incorrectly shows pin 10. V1.0 and V1.1 text matches the diagram for BAND2 OUT. -- Sent from: http://elecraft.365791.n2.nabble.com/ From billamader at gmail.com Sat Nov 4 14:18:28 2017 From: billamader at gmail.com (K8TE) Date: Sat, 4 Nov 2017 11:18:28 -0700 (MST) Subject: [Elecraft] P3 Automatic Power On Failed Message-ID: <1509819508809-0.post@n2.nabble.com> After returning from a contest operation at KS5Z this past weekend, my P3 would not turn on when I applied 12VDC. I checked the jumper and it was in the correct place. I moved and returned the jumper to 2-3 with no change. Re-loading the firmware did not help. I performed a parameter initialization to no avail. I reloaded the current firmware (which was installed prior to the parameter initialization--no change. Restoring the previous configuration didn't change anything. Has anyone else noticed this anomaly? If so, were you able to return your P3 to "normal" operation where applying 12VDC put it into operation? I really like the idea of power on with 12VDC applied! I use this with an APP distribution panel that turns on the P3 and KAT500 when I turn on the K3. The next step is to power on the KPA500 at the same time. -- 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From bruce.rosen at rcn.com Sat Nov 4 18:55:36 2017 From: bruce.rosen at rcn.com (K1FFX) Date: Sat, 4 Nov 2017 15:55:36 -0700 (MST) Subject: [Elecraft] KPA100 100% Duty Cycle - Operating Temperature Message-ID: <1509836136921-0.post@n2.nabble.com> I started running some 100% duty cycle operation with my KPA100 (PSK31 and Olivia).

Get an external wattmeter and check the actual power output. I suspect the actual power is not controlled, and can exceed 150 watts. The usual cause of that problem is damaged diodes D16 and D17 in the KPA100. There will usually be no harm to the KPA100 PA transistors, but the PA transistors in the base K2 can be damaged because they are being stressed to produce their maximum output. Also that condition is likely to give you a distorted signal, and with Data Modes that usually means a high IMD. 73, Don W3FPR On 11/4/2017 6:55 PM, K1FFX wrote: > I started running some 100% duty cycle operation with my KPA100 (PSK31 and > Olivia).

Room temp 20C K2 set to 20W out, 28.5MHz, confirmed by wattmeter. Result: The mosquito came on after three minutes of 20W tune power. 8A from PSU. After about 15 minutes of tune the KPA100 heat sink reached 58C measured by a laboratory thermometer. Hand said the same thing, could only touch it for about three seconds. Set CAL tPA to track cool down and compared with the thermometer. Good agreement. The mosquito shut off at 37C indicated by K2 tPA reading. Conclusion: Seems normal that the mosquito will come on during an extended run of psk at 20W output. The exact timing will depend upon how well the CAL tPA has been set, duty cycle and ambient temp. If you don't like the mosquito then blow the KPA100 heat sink with a small 12V PC fan.

I have the Elecraft W1 wattmeter. At 10 watts or below, the "14 watt" range LED was illuminated. As I rotated the Power knob past 10 watts to just about 12 watts, the "14 watt" LED went out and the "140 watt" LED was then illuminated! So, I've got to replace D16 and D17. Any hints on that replacement job will be appreciated. I found an old forum posting from someone who apparently had a difficult time disassembling the KPA100 to get to the two diodes. Meanwhile, I've to go back and find your e-mail (I saved it somewhere) on bleeding off static charges on the antenna to protect D16 and D17.

Remove the shield and the standoffs - note that the 2 standoffs toward the front are shorter. Then remove the 6 screws holding the PA transistor and Q3 and Q4. There are 3 more screws on the rear panel to remove. You can then remove the board from the heatsink. You may want to unsolder the wires from the speaker, but that is your choice. Locate D16 and D17 near the SO-239 jack. Remove them and replace with new 1N5711 diodes. If you do not have good desoldering equipment, don't fret - if you can't unsolder the diodes one end at a time, crush the diodes and remove the leads one at a time. Clean up with solder wick and if solder remains in the holes, heat the pad and push it out with a wooden toothpick. Normally, just replacing the diodes is sufficient, but you can check your work by powering only the base K2 with the external wattmeter/dummy load (you can do that before mounting the KPA100 board onto the heatsink). If you have proper power control in the low power range, all is well. If not, there may be another problem with the KPA100 wattmeter circuit. BTW, examine the KPA100 board. If it has blue toroid cores (other than the Low Pass Filter), then it is the most recent. If instead you see a red toroid core at L16 and L15, it would be a good time to upgrade it with KPA100UPKT. Also examine the shield - if it has a notch over the SO-239 that is only 3/16 inch or less, it is the new one, and you should also have a shield over the speaker magnet. If both those conditions are not true, add the KPA100SHLDKT. 73, Don W3FPR On 11/5/2017 1:37 PM, K1FFX wrote: > Don, > > You were right on the money with your diagnosis. > > I have the Elecraft W1 wattmeter.

Message-ID: <1509919774136-0.post@n2.nabble.com> My KAT2/100 seems to be acting up. Started noticing high SWR problems with a tuned antenna, so ran further tests with a dummy load. First thing is when I set Menu->AtU-CAL, I get high SWR readings. I thought this was supposed to zero out/bypass the tuner. Clicking of relays is heard but with a dummy load the SWR reading is 4:1 on the LED scale. It's also pulling down the voltage as I clearly hear my outboard fan reduce RPM. If I set it back to Auto, the high SWR remains until I hit TUNE, which quickly takes it down to 1:1 (or something reasonable when using an antenna) Sometimes, if the rig is in high power range I see a momentary HiCur flash at first key down. My current level is set to 3.5A. I have ample output power according to my wattmeter and have been making QSOs, as I can tune out the phantom SWR, but probably I am making the situation worse. Sometimes when I switch bands, the high SWR returns even though the ATU memory should remember the band. Can someone outline a diagnostic path to figure out where the problem may lie? Fortunately, the KAT2/100 is outboard, which makes it easier to access (K-Twins configuration).

Take the top off your K2 and connect the KPA100 directly to the base K2, and do tests into a dummy load. Make certain that the Hi CUR messages do not occur on any band with the power set to 100 watts. You must do a TUNE/DISPLAY to obtain full power. Put a wattmeter between the KPA100 and the dummy load and observe both the K2 display and the external wattmeter. The power reading should be within 20% of each other, and the SWR should be 1:1. If not, you should null and then calibrate the KPA100 wattmeter first. Next, put the QRP top cover on the K2 and test the KAT100 without the KPA100 connected. Plug the control cable into the KIO2 and the KAT100 just as you would with the K2 'twins' - power the KAT100 from the 2.1mm power jack. Still working with the dummy load, balance the KAT100 wattmeter and Balance (null) and calibrate it at 10 watts as indicated in the KAT100 manual. You will have to feed the base K2 into the KAT100 ANT1 and RF IN jacks. Put the cable from the K2 back into the RF IN jack and the dummy load to the ANT1 jack. Then switch the ATU Menu to AUTO and tune all bands into the dummy load. Put the KPA100 back in the EC2 enclosure and again test into a dummy load on all bands. hen go to your antenna and TUNE on all bands of interest. It should tune to an SWR of less than 1.5. Let us know where that testing goes awry. If all goes successful up until you try to load the antenna, check your antenna to see if it has any open connections, bad feedline, etc. 73, Don W3FPR On 11/5/2017 5:09 PM, TI2/NA7U wrote: > My KAT2/100 seems to be acting up.

I agree.? While good bonding and protection devices can help, a large enough or close enough strike can still damage equipment. I set up my station with a panel at which all antennas and control cables from outside can be disconnected with two connectors.? That panel is in the basement shack, and well grounded and bonded to the station ground.? It would be better to have that disconnect outside, away from the house, but I'd never operate in the winter if I had to go outside every time I wanted to connect the antennas.? I would put it outside if I lived in Florida. In addition, all station power comes in on two conveniently placed outlets, one for 120 and one for 240.? I also disconnect both of those when I'm not operating and/or there are thunderstorms around.? (Only the clock is left connected, and it's expendable.) I also disconnect the ethernet cable to the computer.? With everything disconnected, the equipment is grounded, but otherwise isolated.? There is no direct path by which current could flow through any of the equipment.? While some current could certainly be induced in the interconnecting cables, they are fairly short. While I'm fairly sure this protects the equipment well, I know there are no guarantees.? (That's what insurance is for.)? My primary concern is minimizing the chance that a lightning strike will start a fire which, at best, would be a major inconvenience. As far as safety, I stay well away from the radio when there's lightning about. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From marvwheeler at nwlink.com Mon Nov 6 14:46:26 2017 From: marvwheeler at nwlink.com (marvwheeler at nwlink.com) Date: Mon, 6 Nov 2017 11:46:26 -0800 Subject: [Elecraft] N3FJP logging program and K3S Message-ID: <000501d35737$efab6000$cf022000$@nwlink.com> I tried to set up the N3FJP logging program to use with Sweep Stakes this past weekend and was unable to make the software key the radio (i.e. Win4K3Suite).

Message-ID: <201711062002.vA6K23fv012336@mail46c28.carrierzone.com> I looked at the link and opened the Data Sheet. Splitter loss goes from about 3.2 to 4.0 dB in each arm (if terminated) depending on frequency. Assuming use only on HF up to 30-MHz, 3.2 dB. Isolation of ports is above 25.99 dB which should not result in any crosstalk problems (more an issue if used for transmit). Limited to 1w max. Fine for receive. But why would you connect both Rx to a single antenna? You can use both Rx on ANT1 without a splitter. Diversity implies two separate signal sources (two antenna). I do dual polarity Rx on 144-MHz EME by feeding output of the horizontal antenna to sub-Rx and vertical antenna to main Rx (via a two receiver transverter). Special sw processes these two signal after SDR conversion to IQ baseband and converted by four input soundcard to digital. The software both decodes the digital signal (JT65B) and resolves the actual polarity angle of the received signal to one degree. If grid square info of station worked is input it also recommends which polarity (Horz or Vert) to use for transmit. Much more is involved but only germane to those doing eme. http://www.kl7uw.com/MAP65.htm I guess if you want two Rx to see the same antenna it would be a good use, but that does not involve diversity mode. 73, Ed - KL7UW Date: Mon, 6 Nov 2017 08:13:08 -0500 From: Jim Miller To: Elecraft Reflector Subject: [Elecraft] Minicircuits splitter for diversity?

I wouldn't. Actually, F connectors are widely used with RX antennas and RX antenna products, and are the best method to terminate the CATV cables widely used for our RX antennas. It IS, however, important to use decent stripping and crimping tools and good quality connectors that match the cable you're using. The CATV industry likes SnapNSeal branded connectors.

Please email me if you?re interested. See release notes below. 73, Wayne N6KR * * * KX3 MCU 2.82 / DSP 1.52, 11-6-2017 * SIDETONE VOLUME CAN BE SET LOWER: MON=1 is now about 12 dB lower in volume than it was originally. MON=50 is about the same as the original maximum. * AUTO-OFF TIMER RANGE IS 5 TO 100 MINUTES: Auto-power-off (MENU: AUTO OFF) allows the radio to turn itself off if no controls are touched for the specified length of time. (The original range was 3 to 20 minutes.) If auto power-off is not desired, set the menu parameter to INFINITE (default). * VFO A LOCK DISABLES COARSE VFO A TUNING WITH OFS/B CONTROL: This is intended to prevent accidental frequency changes due to touching the OFS/B control. As long as VFO A is locked, the offset-tuning feature will also be locked. (RIT, if used, is still *not* locked. RIT may be needed to fine-tune received signals even if the VFO itself is locked on a given transmit frequency.) Note: Coarse tuning steps for VFO A are set up per-mode using MENU:VFO CRS. The OFS/B control can be used to coarse-tune VFO A if RIT and XIT are both turned off and the control is not assigned to VFO B (?B? LED). * FILTER BANDWIDTH & ULTIMATE ATTENUATION FIX: Filter bandwidth settings ending in x00 Hz are now increased internally to x50 Hz to ensure excellent ultimate attenuation (stop band). For example, a setting of 400 Hz becomes 450 Hz. This is a temporary workaround for a DSP algorithmic issue with the x00 settings that will be corrected in a future release. Available bandwidth settings are now 50 Hz, 150 Hz, 250 Hz, 350 Hz, etc. These are entirely adequate for virtually all operating purposes.

All of that goes to the antenna. If part of that signal would be shunted to a dummy load, I don't think it would be tuned to the correct antenna impedance. I would have to know more about the configuration involved, but to my mind, it sounds like a dummy load is being connected in parallel with the antenna which would upset the impedance to be matched. 73, Don W3FPR On 11/6/2017 6:37 PM, E T wrote: > I understand the requirements, and the ICOM IC-7300 puts out 12.5W by > default (can be adjusted via service menus).

We had a shunt mode MOV "protected" power strip at our family house in New Hampshire. My cousin was using a high power vacuum while painting. The power strip started smoking and he quickly threw it outside where it stopped smoking after a while. When I looked at it, the plastic had be partially melted and there was a significant danger that it could have started a fire if my cousin hadn't acted. It turned out that the electrical system lost its master neutral connection between the service entrance and the pole. The vac dragged down the voltage on its leg so most of the 240 volts was across the power strip's leg. This voltage was enough to pop the MOV. Since the fault wasn't a voltage spike, the MOV overheated enough to start smoking. This whole incident didn't help in my campaign to convince my cousin that electricity is really safe and you don't have to unplug all the appliances, including electric clocks, when you leave the house. 73 Bill AE6JV On 11/6/17 at 1:17 PM, wes_n7ws at triconet.org (Wes Stewart) wrote: >OK, I'll bite:?

An arc that could involve a kilometer or two probably isn't going to be deterred by a meter or so of disconnected coax.? The grandson of my Elmer in the early 50's [who now holds his Grandpa's call] became a lightning scientist. His advice:? Very little [if any] electronic equipment will survive a direct strike on your antenna.? There are many 10's of thousands of amperes dashing around, and lightning arcs very often fork and take more than one path in what appears to be random fashion.? For non-direct hits, this electrical mayhem all still creates EMP's.? The goal is to have everything conductive in your shack to float at the *same* potential.? This means bonding everything together. Connecting that bond to an earth electrode is problematical.? If you do, that electrode should be bonded to the one at the service entrance [which more often than not is a UFER electrode in most late 20th and 21st century construction]. Disconnecting outside can be helpful in some cases.? However, my good friend Tom, K5RC, who operates the Comstock Memorial Station near Virginia City NV, with 7 [or so, I haven't counted lately] towers, some well over 30 m, notes:? "Lightning will just as likely strike a 1 meter sagebrush bush as a 47 meter tower with a 3-el 80 meter yagi at the top."

The KAT500 will remember the proper settings for each frequency segment (see the manual for the size of the segments on each band) and will instantly return to those values at the first hint of rf. So spend some time training the tuner on each band and you don?t have to worry about interference. Once it is trained you can just find a frequency and start transmitting. No tune cycle required. I note you don?t have a K3, but if you did the tuner would automagically follow the transceiver and switch values without any rf at all.

It specifies ?Tuning power required: 5-15 watts?. Would be interesting to know where the other 14.7 watts is going. I?m pretty sure the KAT-500 doesn?t have anything like that. The other thing you can do with the KAT-500 is specify when a tune sequence is initiated. I set mine for 1.9:1. If the SWR is less than that nothing happens. Allows for some variance in the antennas due to weather conditions. You can still initiate a tune if you want to manually, but it won?t do it on its own. The amps are happy below that so no reason to tune.

All my cables from antennas are permanently connected to a well-grounded and bonded panel in the shack.? I disconnect the coax and control cables from that panel to the radio.? Now, if the tower takes a direct hit, that panel, the ground system for the station, and all the equipment may go to many thousands of volts above earth ground, because even my 13 ground rods don't have all that low an impedance.? However, everything in the station should stay close to the same potential.? And, by disconnecting the equipment from everything except ground, there isn't a direct path for current to flow THROUGH the equipment. The hazard, of course, is that there could be an arc from that panel or the station "ground" through the floor or wall of the basement to earth ground.? That's why it would be better to have that disconnect panel outside by the tower 20 feet from the house.? However, having to slog through the snow at 20 below in January would discourage operating.? (And we do sometimes have lightning in January in Wisconsin!)? It's a trade-off I've chosen to make.? I suppose I could put the antenna relays, etc. in a box outside, and disconnect it there in the summer, and have a second disconnect inside for winter.? At this point, however, that outside box would have to get past the aesthetics committee, and she's none too happy with the tower in the first place. About bonding:? Lightning is not DC, and the inductance in any conductor more than a meter or so long can be significant.? All you can do is to try to minimize the bonding inductance by using short, wide conductors. In the 28 years my tower has been up, it has not yet taken a direct hit, though it could in the next thunderstorm.? I've had no damage from nearby strikes. I think lightning IS more likely to strike a tall tower than a short bush.? Using the "cone of protection" concept, I'd expect the probability of a strike to go up as the square of the tower height. It seems as if lightning which, if the tower weren't there, would have hit the ground within the circle at the base of that cone, is likely to hit the top of the tower instead. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From va3mw at portcredit.net Mon Nov 6 21:09:04 2017 From: va3mw at portcredit.net (Michael Walker) Date: Mon, 6 Nov 2017 21:09:04 -0500 Subject: [Elecraft] Minicircuits splitter for diversity?

I had a similar indirect hit in September and I'm still recovering. My K3 lost its serial port, as did the P3. They seem to be working fine now after replacing those boards. A big issue in lightning damage repair is complete testing. If you aren't using your serial port (or ACC connector, or RX antenna port, etc.), you may not notice that something failed until months (years) later when you try to use the bad circuit. So be skeptical and test everything you can think of. The really good news with Elecraft gear is that you can often replace boards like I did. I also lost two TVs completely and one still turns on but has no HDMI inputs left functioning. Similarly, my A/V receiver lost all its HDMI ports. The audio amp still works, but emits a loud POP every minute or two. All four of those boxes are non-repairable and must be replaced. I also had to replace many other devices in their entirety. So Long Live Elecraft! (microbit, by the way, sells a replacement board for its RRC controller for a reasonable US$150, shipped quickly from Sweden. It's a one-board device, but at least I salvaged the sheet metal!) I lost almost every serial and HDMI port in the house. I suspect they're all managed by delicate semiconductor chips that can't handle the pulses. Keep that in mind while testing!

Don't just leave the lead to your antenna hanging. I use very inexpensive switches from epay that have a grounded off. MOV devices only absorb a finite, unpredictable, number of hits. In other words, the next hit may be the device's failure. There are other devices that are better. As with ground fault outlets, you only need one good protective device per AC circuit. In fact, on the ordinary household service, one industrial strength device on each side of the 220 service at the breaker box is needed. Look up "whole house surge suppressor" online. Some of the "best" have mov's. I have not looked lately at availability of non-mov units, which I could recommend. Multiple outlet strips with surge protection have in general mov's that are too samll. I personally don't trust them.

The KAT500 will remember the proper settings for each frequency segment (see the manual for the size of the segments on each band) and will instantly return to those values at the first hint of rf.

I have been disconnecting and unplugging for years. Thought I had it covered when I saw storms coming in on the radar. The next day the radio and the P3 was dead when I plugged the power strip in although the PS was working and everything else fired up. Couldn't get TV and I couldn't use my wireless mouse with the computer. Cut to the chase... The spike came in through the cable, killed the modem, killed the USB hub and the Radio was connected to the hub by the RS232 to USB cable, the P3 was connected to the K3s. Was a new radio, maybe a month old cost me plenty to repair the damage because damage from lightning strikes aren't a warranted item (nor should they be). To Elecraft's credit, they could have charged me more but they genuinely care about their customers and they made it as painless as possible. But my point is this strike didn't come from the power line, it came in from the cable. Lightning is a SOB, if you're going to disconnect, then make it so the rig and everything else in any way possible, is ready to go in a box. FWIW, I now have everything connected wirelessly including the desktop. I still unplug but I no longer worry about spikes through the cable service. 73, Gary KA1J > > On Mon, Nov 6, 2017 at 7:59 AM, Chuck Milam, N9KY > wrote: > > > Hi All: > > > > It looks like we took an EMP hit at home from nearby lightning just > > last night.

It only mitigates the damage. I was CE of a TV station in South Florida with towers of 1,000' a couple at 500' and several more at 100' to 200'. They all got hit at one time or other. Sometimes many times a year. We used massive grounding systems with the tall towers. The towers we rented or on buildings - we had to take what we got. Some were excellent some were non-existent. We operated 24/7 since 1955. We did have redundant equipment. We had two-way antennas as high as 900', microwaves from 100' to 950'. Tower cameras as well. The ENG receive sites (at 950' & 500') had very sensitive LNAs at 2, 7 & 13 GHZ. as well as the pan/tilt steering electronics and drive systems. When possible we did not put electronics on the tower; because of the surge current of a direct strike. A small (tiny?) strike will have over a thousand amp current surge. If the steel tower has a 0.1 ohm resistance, then the top of the tower is 100 volts above the bottom. Any electronics at the top that is connected at the bottom can have that potential on the equipment case (a DC ground loop so to speak) of 100 volts. Most times it is much higher. The least affected equipment were the microwave transmitters and receivers that used waveguide. The signal up and down the waveguide is transmitted rather then conducted. We felt that the best money we spent to mitigate lightning damage were dissipation arrays on all of our towers higher than surrounding structures. Over a 10 year period our lightning damage costs were reduced significantly over the 10 year period prior to that installation. It seems that dissipation arrays are in dispute at this time. It goes to the old adage - that just because you put out elephant repellent and then see no elephants still does not mean the elephant repellant works! My 40 years experience in South Florida as a Broadcast Engineer has taught me that you will find the weakest links in your plant's structure and make them less vulnerable but never be completely immune to lightning damage unless you eliminate all conductors of electricity. Fiber interconnections between studios and towers really helped us reduce the losses. 73 George AI4VZ -----Original Message----- From: Richard Fjeld ...

But having the grounded tower helps bleed off the charge building in the atmosphere in the immediate vicinity, greatly reducing the likelihood of the charge reaching a high enough level to ionize the air and produce a major lightning discharge. Once the air ionizes it becomes a good conductor handling huge currents. But until then, the charge will leak off harmlessly. The voltage gradient always exists. On any day, your head is about 100 volts above the potential at your feet but you don't feel a thing because the currents are so small. Lightning occurs when the charge builds up too quickly for it to bleed off harmlessly. 73, Ron AC7AC -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of john at kk9a.com Sent: Tuesday, November 7, 2017 8:59 AM To: elecraft at mailman.qth.net Subject: [Elecraft] Lightening damage Why would lightning avoid striking a grounded tower?

Most times it is much higher. It is a serious mistake to view lightning as DC. While there MAY be a DC component, lightning is primarily an RF event. IEEE studies show that the energy in lightning is (very) broadly centered around 1 MHz. As far as lightning (and any other RF) is concerned, that tower is an antenna, and must be understood as an antenna. It is also a serious mistake to think of our antennas as the only means by which lightning enters our homes. Lightning comes in on power wiring, telephone wiring, and CATV wiring. It also induces current on wiring within our homes. It is VERY common for lightning currents induced on wired Ethernet cables, connected to equipment with shunt mode surge protectors (MOVs) to fry computers (especially their Ethernet circuitry) in the loop that includes their green wires back to the panel. This happens in homes and offices with no radio antennas at all. All of this is why the most important element of lightning protection, BY FAR, is proper bonding of all equipment and grounds in a building. This is all covered in considerable detail in N0AX's new ARRL book on Grounding and Bonding for hams. It is of FAR greater value than all the surge protectors you could possibly buy. And you can get most of the same information for free from these slides. http://k9yc.com/GroundingAndAudio.pdf 73, Jim K9YC From jwsturges at gmail.com Tue Nov 7 13:00:30 2017 From: jwsturges at gmail.com (Jim Sr Sturges) Date: Tue, 07 Nov 2017 18:00:30 +0000 Subject: [Elecraft] Lighter-than-air (LTA) ships Message-ID: As a young Naval Aviator, many of my elders, including one commanding officer, were former LTA pilots.

Of course the tower is not immune from lightning. Mine has taken many direct strikes and it has a number of ground rods. The ground system gives it a path that is not though your equipment. Also a single point ground and proper bonding as K9YC mentioned will keep everything at the same potential, minimizing damage.

Radios always plugged in. Do it properly (don't trust me - google it). Lots of buried ground rods and copper strap and a single point of ground connection for the radio bench (only). Gas arrestors across all the aerial and rotator connections (and MOV's etc where appropriate). Radio bench isolated from house mains and all other electronic devices (optic fibre to PC). All the lightning arrestors (and MOV's) bolted to a single copper ground bus bar - the single point ground connection is from here to the tower ground system. This keeps the differential voltage across all the radio connections to a minimum. The caveat is - don't operate the radio (manually) in thunderstorms. Of course it's fine via the optic fibre. One lightening hit shook my teeth and made me jump a couple of feet into the air. Most things in the house with running software just crashed.

I wound up using 23 ground rods all cadwelded together with solid #4 copper wire. Everything coming into the house and leaving the house is all tied together to one point common ground. I never disconnect and most of the time I don't turn off equipment. For sure I saw two direct hits. And on one I was in the yard coming towards the house as a store approached. It hadn't started raining yet so thought I was safe. Took a tower hit that knocked me to the ground. The one difference is I took off the MOV's and use gas arrestors. When the MOV's took a hit they would short and take out the driver IC's in the SteppIR controller. I do have a ground position for the cable coming into the shack for the SteppIR controller. 73, N2TK, Tony -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Peter Lambert Sent: Tuesday, November 07, 2017 5:57 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Lightening damage Likewise - 3 direct hits to the tower and nothing in the house damaged. Radios always plugged in. Do it properly (don't trust me - google it). Lots of buried ground rods and copper strap and a single point of ground connection for the radio bench (only). Gas arrestors across all the aerial and rotator connections (and MOV's etc where appropriate). Radio bench isolated from house mains and all other electronic devices (optic fibre to PC). All the lightning arrestors (and MOV's) bolted to a single copper ground bus bar - the single point ground connection is from here to the tower ground system. This keeps the differential voltage across all the radio connections to a minimum. The caveat is - don't operate the radio (manually) in thunderstorms. Of course it's fine via the optic fibre. One lightening hit shook my teeth and made me jump a couple of feet into the air. Most things in the house with running software just crashed. All came good when the power was cycled - nothing was permanently damaged. To say I was relieved is quite an understatement. The 2m collinear at the top of the tower didn't survive.

As a (former) small business owner, I know that is not trivial to estimate. Even more important to achieve. I think my order for a KX3 kit went in within the first day orders were taken and I received SN 475. I know the popularity of the FT-817, having owned one. Only thing it did better was operate crossband VHF/UHF for satellite operation. I now have an old surplus FT-736R which was designed for full crossband duplex satellite operating (also my backup VHF/UHF FM/SSB rig). But never cared for FT-817 small display or mediocre HF performance. I have the atu and 2m module and added the KXPA100, which works really nice as mobile rig. I bought it with 2m promised, thinking of using that as IF for portable mw operating. It will get its first real workout Aug. 18/19 (2018) at the most northern point in Michigan's UP attempting 10-GHz across Lake Superior to MN and ON. That weekend is the first of two for the ARRL 10-GHz Up Contest. I like that I can switch between my K3/10 and KX3 seamlessly to use the KXPA100 (especially on 6m-SSB) at home. I operate VHF Contests on multiple bands so having the KX3 allows me to monitor 6m continuously while working 2m and higher with the K3 plus transverters. I also use dedicated FM radios on 222 and 900 MHz where there is no local SSB activity. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From doug at k0dxv.com Wed Nov 8 18:53:51 2017 From: doug at k0dxv.com (Doug Person) Date: Wed, 8 Nov 2017 16:53:51 -0700 Subject: [Elecraft] Just RX'd KX3 Serial No. 10,028!

I bought this as a way to pass a little time stuck out in the desert and it did the job superbly. Initial testing went well though I am a little concerned that the 20m sensitivity is a little down, might just need a more careful alignment of the bpf. I also need to do a proper setup of the IF filters with the pc. Back home now and on some antennas it seems to be playing nicely. The SSB module, 160m, NB and I/O kits are on hand and will join the family soon. Interesting to note the K2 was, according to Wikipedia, prototyped in October 1997, so that radio is 20 years old and still being produced and more importantly I think is still relevant. Has that bettered the Collins S line? So one of the very latest K2's joins one of the earliest K3's S/N 298. Now I'm starting to think that might need some updating but I'm not sure if there have been any major upgrades to the K3, barring the synthesiser and the S of course.

They require a paddle for sending practice since lessons will be done at 20-wpm. Having researched the topic of 'paddles' and from that effort, I think that a single paddle might work best for me. Here are the negative items which helped form that opinion: 1. a comment that regular practice is needed to maintain competence with a dual-paddle, 2. iambic-a or iambic-b just seem physically complicated. In reading my KX3-manual and Fred-KE7X's book, it seems to me that the KXPD3 is capable of only dual-paddle operating. Or have I missed something? I understand that my KX3 has a second port for an external key (I presume a single-paddle). In the past, I recall seeing photos of hams working KX3-portable with a straight-key but, at those times, I did not pay attention if any had a paddle.

Just don't squeeze it. You make a 'C' with four back and forth motions instead of a squeeze. The connections to the rig for a single or dual paddle are the same. The only difference is in the mechanical design of the paddle. A single paddle cannot close both dit and dah contacts at the same time. With a dual paddle, you can -- but you don't need to. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO http://www.qsl.net/k2vco/ CWA Adviser On 9 Nov 2017 16:14, JEROME SODUS wrote: > Hello, > > > I'm a "no-code-ham" determined to become a "know-code-ham" and so > have signed up to a course by CWops. > > They require a paddle for sending practice since lessons will be done > at 20-wpm. > > > Having researched the topic of 'paddles' and from that effort, I > think that a single paddle might work best for me. > > Here are the negative items which helped form that opinion: > > 1. a comment that regular practice is needed to maintain competence > with a dual-paddle, > > 2. iambic-a or iambic-b just seem physically complicated. > > > In reading my KX3-manual and Fred-KE7X's book, it seems to me that > the KXPD3 is capable of only dual-paddle operating.

Several reasons: The truly high speed guys use single lever paddles--they feel they make fewer mistakes with the single lever. If you learn the single lever technique you can use a dual lever paddle and just not "squeeze" The dual lever technique doesn't save that much time. I think that a lot of the impetus to a dual lever is "CQ", both letters are "squeeze" letters and if you are sending it a lot it is easier to send repeated CQ's with a dual lever paddle. I think regular practice is needed with both single an dual lever paddles. I am fond of my Begali Sculpture single lever, along with my Tony Baleno single lever. If you go single lever, if you occasionally use a dual lever paddle you will be happier with minimal space between the paddles; it's closer to the distance your fingers need to move for the single lever. Begali's Magnum has a very narrow space and I use it as well as my Sculpture single lever. Tony Baleno of N3ZN keys will make a dual lever with what ever spacing between the paddles you want. Hope this helps. 73 Mike KD8RQE In a message dated 11/9/2017 9:31:16 A.M.

There were a few interfaces that used what I think was a Curtis 8044 IC and it was a fantastic chip to learn Iambic with. I had a "Ham Keyer" which used it and later made my own using this chip. It had two settings for Iambic and one seemed more natural than the other so I stuck with it. I then bought a (at the time) new Corsair II from TenTec which had a keyer built in for Iambic but I never liked the way it felt or operated so I stuck with that Curtis chip. When I bought the K3 kit & checked out the built-in Iambic option and it was exactly what I had come to love all along so the Curtis is now on the shelf beside the Corsair for when I'll fire that up again in the future. FWIW, the K3s has that same functionality and I'm guessing the other Elecraft rigs have the same as well. Iambic is efficient, it requires I think, less motions to accomplish the same character and it flows like water with such little effort. I also use a Begali Sculpture but I started with a Bencher Iambic paddle, moved to a Vibroplex Iambic and finally to the Begali. The original Bencher came apart easily and always when I was excited and I had to put it back together (easy to do but not an elegant thing). Maybe they've attended to this flaw by now? The Vibroplex worked very well but seemed to require occasional attention and could have been heavier to stay in place during my moments of exuberance. I ordered the Begali maybe 3 years ago and never have had to touch it. I'm sure the other Iambic paddles made by hand are just as good. I will likely keep this one for what time I have left. As the Iambic from the rig is spaced perfectly as regards timing, it is a perfect teacher as to how to send well. Set your speed, go into the test mode so you don't transmit and practice with headphones to your heart's content. You will find it intuitive and what you will need to focus on is not running your characters and words together as it is so easy to send, you forget the point of error is you and your not sending with the proper gaps between characters and words. The way to best do this on the K3/K3s is to go to test mode! Now push the TEXT DEC on the front panel for decoding CW, select the TX ONLY option and you can read what you're sending on the LCD and this will help you get your character spacing and word spacing down just right. Lastly, I'm sure that whatever key you get, you'll learn how to be comfortable with it. For me, & me being a musician, the timing is everything and again, for me... Iambic was the easiest way to do it right with the least effort. 73, Gary KA1J > Hello, > > > I'm a "no-code-ham" determined to become a "know-code-ham" and so have > signed up to a course by CWops. > > They require a paddle for sending practice since lessons will be done > at 20-wpm. > > > Having researched the topic of 'paddles' and from that effort, I think > that a single paddle might work best for me. > > Here are the negative items which helped form that opinion: > > 1. a comment that regular practice is needed to maintain competence > with a dual-paddle, > > 2. iambic-a or iambic-b just seem physically complicated. > > > In reading my KX3-manual and Fred-KE7X's book, it seems to me that the > KXPD3 is capable of only dual-paddle operating.

Every radio in production supports one, or both, Iambic modes, and they are actually easier to LEARN than they are to UNDERSTAND!? Here is my 2-cents worth: 1.? The best method of sending will be the one you learn first.? This is true of MOST things we learn.? That doesn't mean you can't learn a second method later, but USUALLY the first method will come back to you the easiest. 2.? Reading about the differences in Iambic keying is far more complex than slowing the keyer down and listening to what happens.? Slow down to around 10wpm, hold one paddle down and tap the other to learn how dit or dah insertion works and sounds.? Hold both paddles down and listen to what happens when you release them.? Play with it, but do it at slow speed so you can hear it.? I am NOT talking about learning characters yet.? That should happen at much faster speeds, and after you know what the paddles do to make dots and dashes at the right times.? After playing with this for as long as you need, speed it up a bit and play some more.? Eventually you can work up to the speed CW Ops recommends for learning the characters. 3.? Stop trying to decide between Iambic A and B based on the analysis of what they do or how many paddle movements are required.? You can listen to the differences as I have outlined in 2 above, but simply PICK ONE.? I happen to like Iambic B because I learned on a homebrew AccuKeyer which died years ago.? I can switch to Iambic A with a few minutes of practice, but I prefer Iambic B simply because it doesn't seem to be as sensitive to paddle release after holding both paddles closed in the letter C.? Oops, there I go with too much analysis! 4.? Dual paddles can be used as a single paddle.? I suspect most of the single paddle operatiors were extensive bug users first (again, first learned is the easiest), but I couldn't afford a bug, so I learned Iambic B.? I find that transitioning from Iambic B to single paddle is easy.? I do that when necessary at events like Field Day. 5.? No more maintenance is required for dual paddle modes than for any other mode.? It all depends on what you learned first and what you use the most.? In aviation, a pilot's total flight time is important, but accident reports indicate that recent experience is also important.? Look at the aviation regulations for recent experience and you will see what I mean.? Same for CW. Well, I went over 2 cents worth!

Humorous and instructive: http://www.morsex.com/pubs/iambicmyth.pdf It's a fun skill, but saving nano-calories of effort is questionable for the majority of QSOs. You can use either a single paddle or dual paddle without using the squeeze method. I wouldn't even try learning it until I was competent with a paddle without it. Once you are competent with any paddle, you will find it takes little effort to become accustomed to another. In fact, you will be surprised at how easily you can send either right to left handed or vice versa with little practice. And once you're competent with a paddle, a week or so of practice and you can handle a bug. A bug isn't more difficult. It's just asymmetrical which takes some retraining. Once you are competent with that, you can handle just about anything you want to play with interchangeably. I have more than a dozen different straight keys, bugs and paddles which I quick-change frequently. Sometimes during a QSO. Sort of OT: The W6SFM Bug Roundup is Nov 17-19, next weekend. Its a bug-only version of Straight Key Night. I'll be there with my Drake 2B, Viking Ranger and homebrew left-handed bug (photo on QRZ.com).

I started out around 1956 with a bug given to me by a cousin who had been in the Navy. Sometime in the mid-60s, I switched cold turkey to a keyer. Don't remember what I used for a paddle, but if it wasn't a Bencher BY-1, I soon gravitated to one. I now own 3-4 of them, all bought used from the great auction site. My fingers/brain learned to use a paddle before Iambic keyers had been invented, and I've never tried to change that. Several years ago, I bought a used Begali gold paddle, don't know the model number. It cost as much as I paid for three of the used Benchers, and I find that my fingers/brain send better CW with the Benchers. All are dual-lever paddles. BTW -- the cheapest way to buy a BY-1 is to buy a used MFJ keyer that has a BY-1 mechanically integrated with the keyer's electronics, remove the electronics and throw it away. :) One of my Benchers came that way. One of my contesting buddies brings his N3ZN paddle to our contesting setups. It's a very nice paddle. Why do I own so many paddles? In the shack, one is connected to a WinKey, which my logging software toggles between two radios. Each K3 has a paddle attached so that I can program the memories. In our multi-station contesting trailer, the computer sends the programmed messages and the paddle sends fills. 73, Jim K9YC From ohturoey at hotmail.com Thu Nov 9 14:04:36 2017 From: ohturoey at hotmail.com (ohturoey) Date: Thu, 9 Nov 2017 12:04:36 -0700 (MST) Subject: [Elecraft] Software suggestions for KX3 In-Reply-To: References: Message-ID: <1510254276811-0.post@n2.nabble.com> Dear Sir I have the same setup as you with the KX3 win4k3 and the steinberg UR22mkII I have tried for a long time to get the UR22 to work with my panadapter in win4k3 but with no success I get a double image, left and right of centerline is the same, have tried to adjust but I cant seem to figure it out, if you can explain your cabling setup between UR22mkII and KX3 and your panadapter settings for tuning the bands it would be greatly appreciated please don't be shy to explain it as you would do to a child, this unit has added a few grey hairs to where its already to many picture does also help Best regards Ove VA7OHT/VE0OHT -- Sent from: http://elecraft.365791.n2.nabble.com/ From tomb18 at videotron.ca Thu Nov 9 14:22:31 2017 From: tomb18 at videotron.ca (tomb18) Date: Thu, 09 Nov 2017 14:22:31 -0500 Subject: [Elecraft] Software suggestions for KX3 Message-ID: <796e19a83b671412de8dcaef8ef29e28@smtp.videotron.ca> HiI don't think I ever got an email from you.

Every radio in production supports one, or both, Iambic modes, and they are actually easier to LEARN than they are to UNDERSTAND!? Here is my 2-cents worth: > > 1.? The best method of sending will be the one you learn first.? This is true of MOST things we learn.? That doesn't mean you can't learn a second method later, but USUALLY the first method will come back to you the easiest. > > 2.? Reading about the differences in Iambic keying is far more complex than slowing the keyer down and listening to what happens.? Slow down to around 10wpm, hold one paddle down and tap the other to learn how dit or dah insertion works and sounds.? Hold both paddles down and listen to what happens when you release them.? Play with it, but do it at slow speed so you can hear it.? I am NOT talking about learning characters yet.? That should happen at much faster speeds, and after you know what the paddles do to make dots and dashes at the right times.? After playing with this for as long as you need, speed it up a bit and play some more.? Eventually you can work up to the speed CW Ops recommends for learning the characters. > > 3.? Stop trying to decide between Iambic A and B based on the analysis of what they do or how many paddle movements are required.? You can listen to the differences as I have outlined in 2 above, but simply PICK ONE.? I happen to like Iambic B because I learned on a homebrew AccuKeyer which died years ago.? I can switch to Iambic A with a few minutes of practice, but I prefer Iambic B simply because it doesn't seem to be as sensitive to paddle release after holding both paddles closed in the letter C.? Oops, there I go with too much analysis! > > 4.? Dual paddles can be used as a single paddle.? I suspect most of the single paddle operatiors were extensive bug users first (again, first learned is the easiest), but I couldn't afford a bug, so I learned Iambic B.? I find that transitioning from Iambic B to single paddle is easy.? I do that when necessary at events like Field Day. > > 5.? No more maintenance is required for dual paddle modes than for any other mode.? It all depends on what you learned first and what you use the most.? In aviation, a pilot's total flight time is important, but accident reports indicate that recent experience is also important.? Look at the aviation regulations for recent experience and you will see what I mean.?

I've encountered far more nearly-impossible or impossible to copy fists from commercial operators aboard ships than I've heard on the Ham bands. I certainly would never want to deter someone learning Morse from using it on the air, even if the best they can do is a roughly sent Name-RST-QTH-73 QSO.

Perfect code remains the goal because it conveys the greatest chance of 100% copy. My post was not directed to beginners but to any CW operator so confident of his fist that he refuses to find out what the guy on the other end is hearing. For the last ten years I have taught as many as three Morse Code classes every Saturday morning and have insisted that for code purposes the mantra is, "there are 27 characters in the English alphabet, the 27th is a space, and that 27th is the hardest to learn." The most important CW feature on Elecraft products is the decoder.? Not for copying code, but for copying sending.? When used, one quickly realizes he's not the hot-shot code man he thought he was.? FISTS members suddenly tumble to the fact that all these years they've been sending "CQ FISB" instead of "CQ FISTS."? The first week I played with my K3, I was taken aback by how many times I was sending "CQ DEK9ZTV." It's not the end-of-the world either way, but if Morse is worth preserving, is it not worth preserving correctly? 73, Kent?

I'll try and do that, in 12 sections: a.? Regular practice is necessary to send Morse code well, especially when learning.? The flavor of paddle, bug, or key doesn't matter.? Once it's in your head, it will be there for the rest of your life.? I was QRT in the mid-60's for 4 years while in SE Asia.? Once I came home and got back on the air, I was back to my normal in a month or so. b.? The only difference between single-lever and dual-lever paddles [aside from the number of levers [:-) ] is that you can close both the dit and dah contacts at the same time on a dual-lever.? With an Iambic keyer [i.e. "squeezing], closing both will send di dah di dah di dah di ..., or alternatively dah di dah di dah ..., depending on which side was closed first.? You can use a dual-lever paddle just like it was a single-lever paddle however -- I do and always have, and many other non-iambicized hams do too. c.? I described Iambic-A above in (b).? Iambic-B allegedly arose from a logic misteak in a keyer chip.? Iambic-B will send a single element on it's own when the paddles are released.? If it is making a dit when released, the extra element will be a dah, and vice versa.? Incidentally, all of today's keyers are self-completing ... they will always send correct length elements.? If you're sending a dah and release early, it will go ahead and complete the dah. d.? It seems that whichever mode you learn on will become "your" mode.? Once learned, most people have a hard time using the other mode, however I've never seen any empirical evidence that one mode has advantages over the other.? With either mode, there are about a half-dozen or so letters that you can complete with fewer finger movements using Iambic.? I've never seen the advantage, but some do and to each his own. e.? Yes, the KXPD3 is a dual-lever paddle, however it can be operated as a single lever paddle as well.? The KX3 has an Iambic keyer that can be set either mode A or B [or Ultimatic, or bug mode I think] f.? Yes, the KX3 and practically all radios on the market today have a KEY input.? It is a two-wire circuit, and when in CW mode, short the two wires and you transmit for as long as they are shorted.? This is also used with external keyers [WinKey, Microham, etc] where the external keyer forms the code elements from paddle input or ASCII characters from a computer.? The transmitter things it has a straight key in the KEY jack. g.? Yes, for CWA, you will need to be able to send to yourself. You can put the KX3 into TEST mode.? It will act as if it's working normally, it just won't make any RF. h.? While the KXPD3 is perfectly good for the KX3, it is very small.? I'd recommend obtaining a larger paddle [single- or dual-lever, it doesn't matter] at a reasonable price while you're learning Morse.? The Bencher BY-1 is a very good choice, you can find them in several finishes on eBay, eHam, and at swap meets.? I have 2, one black base and one chrome.? Last time I noticed, they were in the $40-50 range.? The Hexkey [also by bencher] is a somewhat more expensive choice, Elecraft used to sell them, they may still. i.? "Normally," paddles are configured with dahs on the finger(s) and dits on the thumb, however there is exactly zero magic in that, it's a holdover from the pre-keyer days with mechanical bugs.? You could get a "left-handed bug" but they were special-order and very pricey. ?? Nearly every keyer today allows you to "invert" that connection with a menu or control character. j.? There is one advantage to configuring your paddle in the "normal" manner ... that's how most stations are configured and if you are a guest op, it will be right for you. k.? A lot of left-handed hams learned to send [and subsequently paddle] right-handed because in the olden days, keeping a log was a Really Big Deal.? Send right, write left.? Strangely, almost no right-handers learned to paddle left.? I'm a lefty, I learned to send right, but when logs ceased to be an RBD, I put a second paddle on the left which I tend to use in casual QSO's.? You can do whatever works for you and you're guaranteed to be "right." Being able to paddle right-handed is an advantage if you ever are a guest op too. l.? I don't know your age but a combination of injuries to my hands in my 20's, a genetic condition [poor choice of Dad], and an accumulation of birthdays took a toll on my ability to send at 35 even though I could copy it.? I finally purchased an N3ZN single-lever as a fairly expensive experiment.? Fortunately, I find the combination of single lever AND very precise engineering and design of the ZN paddle has brought my reliable sending speed up to 25 or a little more. I notice that you've gotten several replies that assert [I'm paraphrasing]: "You should never transmit Morse until you've practiced off-line for at least half your life."? Jerry, that is the same "advice" you can find in a feedlot full of male bovines. It's in the same category as, "You should never send on a bug [nowadays that includes 'keyer'] until you can send War and Peace in its entirety with no mistakes on a straight key."? If your CW isn't perfect, so be it.? The best way to become fluent in Morse code is to get on the air and use it.? If someone thinks your fist stinks, he doesn't have to answer your call.? Getting on the air is also the best way to discover all the things you can do with Morse and why it appeals to so many. [Full disclosure:? I'm a member of CWOps]:? Congratulations on starting CWA.? That CWOps program has many graduates, some learning from scratch, some seeking to improve their ability in the mode.? Their method works, the Advisors are extremely good at applying it, and I look forward to a QSO with you in the near future. 73, Fred ["Skip"] K6DGW #142 Sparks NV DM09dn Washoe County On 11/9/2017 6:14 AM, JEROME SODUS wrote: > Hello, > > > I'm a "no-code-ham" determined to become a "know-code-ham" and so have signed up to a course by CWops. > > They require a paddle for sending practice since lessons will be done at 20-wpm. > > > Having researched the topic of 'paddles' and from that effort, I think that a single paddle might work best for me. > > Here are the negative items which helped form that opinion: > > 1. a comment that regular practice is needed to maintain competence with a dual-paddle, > > 2. iambic-a or iambic-b just seem physically complicated. > > > In reading my KX3-manual and Fred-KE7X's book, it seems to me that the KXPD3 is capable of only dual-paddle operating.

In-Reply-To: References: Message-ID: As a follow up: Thanks for all the suggestions. It appears I really don't want a splitter after all once I looked over all the schematics on the K3s and Fred's nice book. I can't use my TX antenna as one of the antennas in a diversity setup since it is far too close to my RX vertical array. So when listening I detune my TX antenna. And of course it not only lacks sufficient distance but is of the same polarization as my RX array. I only have 1 acre here and my antennas are pretty much limited to the rear half of the lot. I've done more research and it seems that for 160 the usual suspects are all vertically polarized: small loops, beverages, K9AY. So what I really need is something with horizontal polarization and so far that means a dipole. Not clear that a lowish, short dipole will hear much on 160. It might be useful for 80m however and I have height and space for that. Or I need to buy a couple more acres if I want to do something useful with diversity on 160. 73 jim ab3cv On Mon, Nov 6, 2017 at 8:13 AM, Jim Miller wrote: > I'm looking at this splitter to set up diversity for my K3s.

I have asked Wayne many times if he would implement it. In fact I bugged him about it for the K2 as well. That way, I could use dual lever paddles. The way it is right now, only Iambic (mode A or B) is available. For those not familiar with Ultimatic mode, the way it works is that there are no alternating dots and dashes. When you tap the dot paddle, a string of dots is sent (nothing different so far), same for the dash paddle. But if you have the dot paddle closed and then close the dash paddle, a string of dashes will be sent (not alternating) - same if the dash paddle is closed and the dot paddle is then closed. In other words, the last paddle closed takes precedence. This allows for symbol insertion, and the paddle operation is just as efficient (or more so) than iambic. I believe this was the mode used by one of the older electronic keyers - the W9TO keyer if I recall correctly. I learned some bad habits using a bug - I used one side of the paddle to push off the activation of the other paddle side. I just cannot seem to break that old learned behavior. The K1EL series of keyers includes Ultimatic, although I now use a single lever paddle to achieve the same behavior. With a single lever paddle, it is not possible to close both the dot and dash contacts. If Wayne would implement Ultimatic mode, I could use the dual lever paddles attached to the KX3 and KX2, but as it is, I just send garbage because of the alternating dots and dashes. 73, Don W3FPR On 11/9/2017 6:35 PM, Fred Jensen wrote: > The KX3 has an Iambic keyer that can be > set either mode A or B [or Ultimatic, or bug mode I think] From donwilh at embarqmail.com Thu Nov 9 19:40:01 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Thu, 9 Nov 2017 19:40:01 -0500 Subject: [Elecraft] CW paddle trivia In-Reply-To: References: Message-ID: <2081c894-f00e-5c00-01ed-26d43c038fa4@embarqmail.com> Or for the K2/K3/K3S/KX3/KX2, there is a menu item that will reverse the paddles.

Yes, those values are the power and SWR as measured by the KPA100 wattmeter. Given your readings along with the HI CUR messages, I believe there is a problem with the KPA100 wattmeter. To test that theory, connect an external wattmeter to the KPA100 and a dummy load. Set the power to 50 watts (or 5 watts if powering only the base K2). Then do a TUNE. Do you have power control? Or does the power output go to maximum (greater than 15 watts if only the base K2 is powered, or greater than 120 watts if the KPA100 is powered. If there is no proper power control, then the wattmeter in the KPA100 is damaged. The most common cause is that KPA100 diodes D16 and D17 have been damaged. If changing them does not cure the problem, then there are other components that could be the problem. Let us know what the results of your testing may be and we can help further. 73, Don W3FPR On 11/9/2017 6:08 PM, TI2/NA7U wrote: > I see that the small aux board must be removed as there is a "null" pin in > the plug and cable, so went ahead and did that and hooked up the KPA100 with > its RF out to the meter to the dummy load. > > When I hold TUNE/DISPLAY, I get a display that looks like > with values when power is turned all the way down: 0.1 1.2-1 and all the way > up 4 2.1-1 Is that pwr and swr? > > If I key down the display reverts to frequency immediately, so seems I can't > use TUNE/DISPLAY to monitor the power setting or key down output. > > As I turn the power up or down I get HiCur almost constantly until I let go > of the power button.

I have two loops phased with an NCC-1, but I often use one or both of them in diversity with one of my TX verticals. Spacing between them is only about 100 ft. Consider using one of these loops in diversity with your TX antenna. > I've done more research and it seems that for 160 the usual suspects are > all vertically polarized: small loops, beverages, K9AY.

Not clear that a lowish, short dipole will hear much on 160. It > might be useful for 80m however and I have height and space for that. Horizontal dipoles, even low ones, can be good RX antennas. For 160 contests, N6RO patches lots of his antennas for other bands to his operating position for RX and switches between them. Note the difference in the vertical pattern of the VE3DO loop and a Beverage, or of a vertical. The VE3DO loop has a lot of high angle, whereas the TX vertical has a much lower vertical pattern. Signals may arrive high during one part of an opening and low at a different time. Don't get hung up on polarization, and don't let the ideal be the enemy of the good. Last spring, I bought an 8x2 RX antenna switcher, and started using it on the lower bands, especially 160-40. Around the same time, I rigged the VE3DO loops and ran them to an NCC-1. Anything worth doing is worth doing to excess. :)? Every time I dig for a weak signal or try to kill QRM or noise I learn something new. Also remember that slow fading (what has long been called selective fading) on the lower bands is really the cancellation of two arrivals of the same signal arriving that have traveled slightly different paths, and are thus shifted in time from each other. The phase difference between them will be different at every point in space, so when they are equal and 180 out of phase at one point, they often will not be at another point. The deep nulls in a fade are with the signals are very precisely equal and very precisely 180 out. Without that precision, there will be far less cancellation, and it doesn't take much a lot difference to make the null far less deep. Picket-fencing at VHF and UHF is exactly the same phenomenon -- the difference in the period of the fade is entirely due to wavelength. 73, Jim K9YC From ebasilier at cox.net Fri Nov 10 01:55:23 2017 From: ebasilier at cox.net (Erik Basilier) Date: Thu, 9 Nov 2017 23:55:23 -0700 Subject: [Elecraft] kxpd3 question In-Reply-To: References: <563385831.235670.1510236882215@connect.xfinity.com> <89c7be1f-3a23-247a-80fb-947782590550@gmail.com> Message-ID: <005a01d359f0$e1c0ac00$a5420400$@cox.net> I normally use either a dual paddle Begali or Bencher, but recently I purchased a (dual paddle) Palm paddle for portable operations. At this point, I haven't had time to play with adjustments, but adjusted from the factory it feels distinctly soft under finger pressure, almost like the lever itself were flexible. What really surprised me is that this "softness" felt so natural. It is almost like it reduces my mistakes, and makes sending easier than with my other paddles. I suppose the Bencher has a slight amount of flexing too, but nothing like this. I wonder if any other paddle models also make softness an asset. Maybe there is a downside with the softness when one pushes the speed higher. I haven't tried that yet. 73, Erik K7TV From kl7uw at acsalaska.net Fri Nov 10 02:09:12 2017 From: kl7uw at acsalaska.net (Edward R Cole) Date: Thu, 09 Nov 2017 22:09:12 -0900 Subject: [Elecraft] kxpd3 question Message-ID: <201711100709.vAA79Zvf012049@mail46c28.carrierzone.com> When I was studying for my Novice (1958) I did not have a code practise machine (did borrow one for a week), so I practised by sending to my self with a straight key. I found a way to set my super-regen receiver such that by grounding a spot on the board caused it go into oscillation with resulting tone in the speaker. I got very good at sending up to 20 wpm with the straight key. I bought a Bencher about three years ago and have yet to master using it. Guess its either straight key or keyboard. Keyboard actually is better on eme because I can have several canned replies saved and click to send them, Machine CW is perfectly formed. eme'rs suggest 15-17 wpm as optimum due to fading off the moon. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From ebasilier at cox.net Fri Nov 10 03:12:38 2017 From: ebasilier at cox.net (Erik Basilier) Date: Fri, 10 Nov 2017 01:12:38 -0700 Subject: [Elecraft] Useful radio features Message-ID: <006101d359fb$ac713500$05539f00$@cox.net> Frustrated by the weight, size. cost and wires of a KX3 + KXPA100 combo for light 100W portable operation, I got a Yaesu FT-891 (but keeping the KX3 which is superior when 100W is not needed). Going into this I knew that the 891 has horrible phase noise, but that is of no consequence since this radio is not for operation in town, nor in multistation contesting, where nearby stations would be bothered by the phase noise. What I got is a radio about the same size as the KX3, but putting out 100W, with a weight of about 5 lbs, and a price under $600. Yes, it relies on fans, but they are not very loud. The whole 100W radio is about the size of a smallish 50W VHF FM rig. This suggests to me that Elecraft might want to design a KXPA100 that is much smaller and lighter than the current model, and using fans. The FT-891 architecture is similar to the K3 in important respects. A roofing filter is used in conjunction with audio frequency DSP processing for final selectivity and noise reduction. Many current high end rigs that seem to have copied such elements of the K3 design, but in a cheap radio this is not common. Performance of the FT-891 in the presence of strong signal interference is not competitive with the K3, but it is not bad. Noise reduction is quite good, and probably competitive with the K3 based on my very limited testing. But the 891 has an additional tool that is very useful for improving voice copy. They call it "Contour". I would call it a parametric equalizer. It also reminds me of an old-time Q-multiplier. The RX and TXequalizers of the K3 are very effective, but since they are "graphic equalizers", it takes a while to set one up. Most of us adjust the K3 receive equalizer at most once, and never during a QSO. When I listen to weak SSB signals in the presence of strong noise, even when using NR, on e.g 40m, it turns out that, at least with the FT-891, a very worthwhile improvement can often be achieved by fine-tuning RX equalization. On the 891 this can be done very quickly thanks to the parametric approach to equalization. Instead of varying a series of settings to create a response curve point by point, we select a frequency to boost or suppress. The width and height of the peak or valley are adjustable, but most of the time we don't need to change those in order to make a meaningful improvement in copyability. If the other station had optimized their TX equalizer (if they even have one), no RX equalization on our end would be needed, but listening at random I find most signals become easier to copy after a little RX equalization tailored to the particular station, The notching mode, with a moderate notch depth and width is often wide enough and shallow enough to create pleasant voice reception by applying it somewhere inside the passband, while deep enough to change effective passband width if applied to the edge of the passband as a fine adjustment to the DSP bandwidth setting. All of this is somewhat surprising to me in terms of how effective and easy it is to use. Some reviewers of the FT-891 have claimed that with the FT-891 they can copy a station that cannot be copied on a much more expensive radio. I have not compared side-by-side with an Elecraft radio, but it seems to me that those reviewers are talking about something real and significant. I am writing this to suggest that the K3 and other Elecraft radios could be improved by adding parametric equalization to the existing array of receive enhancement tools. 73, Erik K7TV From steve.steltzer at yahoo.com Fri Nov 10 06:09:01 2017 From: steve.steltzer at yahoo.com (Steve Steltzer) Date: Fri, 10 Nov 2017 11:09:01 +0000 (UTC) Subject: [Elecraft] Perfect code References: <103879672.154544.1510312141398.ref@mail.yahoo.com> Message-ID: <103879672.154544.1510312141398@mail.yahoo.com> Good morning gentlemen, ????As Kent and Gary said, timing is everything and sending perfect code should be the goal of every op.

If you are musically oriented its an easy thing to slip into. I haven't tried using a straight key since having my right hand forefinger shortened (partial amputation early Sept.) but think I will be OK with the straight key. Paddle NO; my middle finger coordination is not anywhere what had with my forefinger: Try clicking left mouse button with middle finger! learning how to write with pen and pencil all over again (or make believe I am a doctor writing prescriptions scribble). No more gun shooting with missing trigger finger. Soldering seems to be OK as I always held parts with left hand. So (probably) I will resort to keyboard sending CW. For CW-eme I can have common scripts prerecorded for push button send. But typing on querty keyboard with one finger missing is another challenge. E-mail is a good training tool, as I can correct errors before sending. Left hand sending - Ha Ha I am having to do things that require strength left handed (pressing spray can buttons). No strength in middle finger (only good for Italian hand signals-capice?). 73, Ed - KL7U http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From k6dgw at foothill.net Fri Nov 10 14:29:58 2017 From: k6dgw at foothill.net (Fred Jensen) Date: Fri, 10 Nov 2017 11:29:58 -0800 Subject: [Elecraft] Keying In-Reply-To: <1243250785.27666.1510286972526@mail.yahoo.com> References: <1243250785.27666.1510286972526.ref@mail.yahoo.com> <1243250785.27666.1510286972526@mail.yahoo.com> Message-ID: <31002220-65ca-306d-29e5-dc01c800ac9c@foothill.net> Yep, the J-36 I had as a teen in the 50's was a great bug, but only because it was manufactured by Lionel, of model train fame.?

F. Scotten, W6ZMZ.? He noted that our keyers [they existed then, just fairly primitive] send the well-formed dits and dahs. The spacing is up to us.? His astounding discovery was that, if our keyers sent well-formed spaces instead, we'd have textbook quality CW on the air, the dits and dahs just fall out automatically! He offered a test sentence, "Then after Richard had arrived, he and Clarence each kissed beautiful Annabelle and she ceased all resistance because in actual fact, she liked it better than ever."? Aside from this being a remarkably racy sentence for QST in 1949, it allegedly does not contain two or more consecutive dashes and, he posits, is very hard to send accurately with proper spacing.? It doesn't seem too hard for me, but then my keyer wouldn't exist for another 55 years although it still sends dits and dahs. Since I ran across the miracle of the Humbug, I've often wondered why it appeared in October and not April, but nevertheless, you can work it out on paper ... send the spaces instead of the dits and dahs, use a keyer to make the spaces well-formed, and you get perfect code. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 11/10/2017 4:49 AM, Arthur Nienhouse wrote: > */Often its because of poor spacing running everything together or > sending the dah with half the > correct length, *timing and spacing* timing and spacing*.

You should also turn off MIC BIAS which results in a cleaner signal - the mic then gets its bias from the LOGIC residual voltage that is normally applied to the ring. You can use the XMIT button to initiate transmit, or use VOX. That may be inadequate for your purposes since you need to activate PTT from your sequencer. The only alternative is to build a special cable or as has been suggested several times on this reflector, use an adapter with a stereo male plug and one jack that connects to the ring and another to the tip. You might search the archives to see some of the sources and part numbers. If you use an adapter like that, you do not have to turn off MIC BTN and MIC BIAS. The stereo plug does connect the LOGIC ground and the Signal ground together, but no apparent harm has been mentioned because of that. 73, Don W3FPR On 11/10/2017 2:58 PM, Edward R Cole wrote: > Guess finally time that I consider a Yamaha CM500.?

The bias voltage then uses the residual voltage that is developed on the ring connection. The reason that works is because the computer mics have the tip and ring connected together.

I've been in the hobby since 1957. CW has always been used as some sort of ham radio purity test. It was used to keep people out of the hobby altogether for decades. Many of those who persevered, learned the code under duress to get their license, then never touched a key again. And there's no evidence CW as a gatekeeper prevented lids as many of the worst offenders were General class or higher who had to have passed a code test. As empty as the CW portions are now, except during any contest, I welcome anyone who knows enough code to make a QSO. Perfect code is not necessary for reliable communication.

I built 1331 (a doppelg?nger) a long time ago. I built 5226 also a long time ago. Gosh, building them and the accessories were the best kit builds I ever did. The suggestion that it has achieved a place along the HRO-60, Gold Dust Twins, S Line or Drakes does merit the K2. Unlike Heathkit point to point wiring it was replaced by a modular PCB mounting scheme. That was revolutionary and made so many succeed. I would vote the K2 into the radio hall of fame based on the innovative modular design. Joe N9JR > On Nov 10, 2017, at 4:20 PM, Robert G Strickland wrote: > > Martin... > Congradulations on K2 #7723.

It does *not* apply to the K3 which *must* have bias turned on to use any Electret microphone, whether by Heil, Yamaha or Koss. In the K3 the ring on the microphone socket is *floating* and can obviously not by used for an alternate source of bias. I verified that the Yamaha and Koss both have the tip and ring connected together. The Heil comes with a mono (TS) plug. All of this is compatible with the K3 if the bias is turned on. I am not sure what's up with the KX3 and the "cleaner" audio achieved with the bias turned off. It seems to me that this is not a choice that users should have to make. Until I saw this thread, as far as I know the advice was to always (for both the K3 and the KX3) turn bias on to use any Electret microphone AB2TC - Knut Don Wilhelm wrote > Ed, > > You can use the stereo mic connector directly into the KX3 if you turn > MIC BTN off in the menu.

I am not certain why you think this is a KX3 "problem". The tip and ring connected together is a characteristic of all microphones intended primarily for computer use - and the Yamaha CM500 is one of those. The ham microphones normally have a mono plug, and do not apply, although with mono plugs, MIC BTN must be turned off in the KX3/KX2 so that PTT is not activated when the mic plug is inserted (the shell grounds the PTT ring). The normal computer jack applies bias to the ring, not the tip. In the KX3, there is residual voltage from the MIC BTN circuit applied to the ring even with MIC BTN turned off - the combination of the tip and ring connected together and the residual voltage from the mic button circuit in the KX3/KX2 is why it works that way. That is true of both the KX2 and KX3 - yes, it does not apply to the K3/K3S which has no connection to the ring contact in the jack. So not a "problem", it is just the way things work. 73, Don W3FPR On 11/11/2017 9:12 AM, ab2tc wrote: > Hi, > > This thread had me thoroughly confused for a while, but I now realize that > it applies to the KX3 and KX3 *only*.

First, I don?t think it is accurate to suggest that CW was used to keep people out of the hobby. The requirement for this skill was much less obtuse than that. It was simply due to the fact that CW was/is probably the most basic method of communicating?at least it was for a long time. You could touch two wires together and send a coherent message! The device necessary to transmit such a signal was about as simple as it gets. CW is still far more efficient and effective than voice modes unless you use considerably more power with the latter. One shouldn?t lose sight of the fact that a dominant reason for us even being allowed to practice this hobby was that we could be a reliable alternative in case of emergency. There was a lot of competition for our place in the spectrum. I don?t disagree that ?perfect code? isn?t a mandate, but I do think it should be an objective. The farther away you get from perfect code, the less coherent it becomes. The closer you get to perfect code, the easier it is to interpret! Plain and simple! I hear a lot of crap CW on the bands. Some of it comes from folks who are just not very good at it, but are trying to get better. I?m not so bothered by that. However, those who don?t do CW very well, and don?t care, and don?t have any intention of getting better at it, don?t interest me very much. Trying to copy bad CW is a lot of work, and it is rather frustrating. If I?m helping someone get better, it is worth it, but if I am just enabling someone to not get better, I don?t see the point of it. As to the comparisons to accents that Ron made in his post, I would suggest that there is a distinction as to degree. It?s one thing to be ?identifiable? because of some slight variation from perfect code, much like an accent in language is, but it is a completely different thing to be so far from perfect code that you become hard to interpret. That?s not just an accent, but more like using poor grammar! CW is, in effect, a language, and should be recognizable without excessive strain. My CW is far from perfect, but I try to make it sound as much ?by the book? as I can. I definitely don?t try to jazz it up like some people do. Every so often someone comments that they find it easy to copy. I?d much rather hear a comment like that than have someone say they recognized my because of my accent! Cheers! Dave W7AQK -------------------------------------------- From: Eric J I'm with Ron. I've been in the hobby since 1957. CW has always been used as some sort of ham radio purity test. It was used to keep people out of the hobby altogether for decades. Many of those who persevered, learned the code under duress to get their license, then never touched a key again. And there's no evidence CW as a gatekeeper prevented lids as many of the worst offenders were General class or higher who had to have passed a code test. As empty as the CW portions are now, except during any contest, I welcome anyone who knows enough code to make a QSO. Perfect code is not necessary for reliable communication. Besides, I love hearing all the various fists, and enjoy recognizing individuals by their fist.

For at least the last 20-30 years of the 20th century, CW was used as a means of keeping the hobby "pure," a "rite of passage" that all current licensees had had to take, and that, anyone else wanting to enter their hallowed ground must also take. You had to be not paying attention not to be aware of this. It was easy to not be paying attention -- many of us, including me, were on and off the air for decades at a time as we lived our lives with jobs, families, even other interests. This was not unique to the US -- the CW requirement was from international governmental bodies. Our large contesting club includes at least a dozen no-code licensees who have developed into fine CW operators and serious contesters. Recently, I heard of a ham club a few hours away from me that developed out of the interest of a local community organization in emergency communications -- this is a low population density community in the Santa Cruz mountains north of me, where the potential hazards are wildland fires, winter storms, and earthquakes. Here's a link to photos from this year's Field Da. Notice the number of young hams on the air in the photos of the stations. http://www.sc4arc.org/groups/general/forum/topic/field-day-photos/ Some of the photos show a pretty serious effort with antennas, and communications on their blog show well organized planning.

Virtually all mics should have the low end rolled off for use in a ham station. This will also help a lot with wind noise and with other noise in the shack. Go to TXEQ and start by setting the bottom three sliders to full cut (that is, -18 dB), and the fourth slider to cut at least 6 dB. Most mics benefit from 3-6 dB of boost on the two highest bands, but no more. For directional mics like Bob is describing, you may want to cut the fourth band even more. This is the time to get signal reports from trained listeners. The objective is to have good, crisp vocal sounds, but with very little bass. Bass wastes transmitter power, makes speech harder to understand, and also boosts noise. 73, Jim K9YC From kevinr at coho.net Sun Nov 12 01:17:19 2017 From: kevinr at coho.net (kevinr) Date: Sat, 11 Nov 2017 22:17:19 -0800 Subject: [Elecraft] Elecraft CW Net Announcement Message-ID: <64ed8f48-688a-d0ed-fc44-b421c07b6a75@coho.net> Good Evening, ???

It could be a school, a non-profit club, an NGO, whatever, and it could be anywhere in the world to which the collection could economically and politically be shipped. Suggestions are requested.

I was twelve when I discovered "hams" talking on 75m AM. It was not the morse code that attracted me to ham radio - it was talking. But I quickly found out that the gate to getting into ham radio required learning morse code. I got 5wpm pretty easy and became a Novice at age 14. A year later I took the General Class written exam and became a Technician. Several attempts to pass 13wpm which involved a 68 mile drive to FCC in Detroit resulted in failure. I started college as an EE student, way too busy for working on code, graduated to start my career which included nine years working for JPL-NASA where I became a senior engineer at age 32. I got to help several missions to the planets, but I was "not qualified" to be a "real ham" because of code. Finally in 1982 (age 38) I spent the effort to pass the 13wpm test (which then only required answering 7 out of ten questions vs 1 minute perfect copy of five character random groups). I took my Advanced test and passed (never had a General). In 2000 FCC lowered speed requirement for Extra to 13wpm and I passed with two wrong answers. BTW I took and passed the 2nd Class Radiotelephone in 1971 (which is way harder than extra). 24 years I had to wait to become a "real ham". Well the good result was that I got interested in 2m (where I could talk) and that lead to microwaves and eme. EME required CW when I started in 1998 but fortunately digital arrived (JT44) in early 2000's which I have been using on 2m and a little on 1296. I will eventually get up to 15wpm because I want to work eme stations that only do CW. But as a boy, I just wanted to talk on ham radio. Eliminating CW as a requirement does make it easier today. Longevity of ham radio does not depend on it. My local club has only 2-3 members that are not retired. No youngsters under 35. I am currently learning about using a Raspberry Pi in a autotracking system for my eme antennas. Plans to install dual-yagis for 6m-eme and a 100w 3400-MHz system on my 16-foot dish. Guess some of the engineer remains, as well. 73, Ed - KL7UW _._ From: Jim Brown To: elecraft at mailman.qth.net Subject: Re: [Elecraft] kxpd3 question Message-ID: Content-Type: text/plain; charset=utf-8; format=flowed On 11/11/2017 9:45 AM, dyarnes wrote: > I don?t think it is accurate to suggest that CW was used to keep people out of the hobby. For at least the last 20-30 years of the 20th century, CW was used as a means of keeping the hobby "pure," a "rite of passage" that all current licensees had had to take, and that, anyone else wanting to enter their hallowed ground must also take. You had to be not paying attention not to be aware of this. It was easy to not be paying attention -- many of us, including me, were on and off the air for decades at a time as we lived our lives with jobs, families, even other interests. This was not unique to the US -- the CW requirement was from international governmental bodies. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From phystad at mac.com Mon Nov 13 13:21:59 2017 From: phystad at mac.com (Phil Hystad) Date: Mon, 13 Nov 2017 10:21:59 -0800 Subject: [Elecraft] CW In-Reply-To: References: Message-ID: <80EFCA69-DCDA-4D68-9532-636D5004154E@mac.com> I was a shipboard comms officer for several days, part of mornings actually -- well, not officially and definitely not paid the big $$$. When I was 14 and my copy speed about 20 wpm back then, I spent two weeks on my dad's ship (he was Captain of a cargo ship). I hung out in the radio room quite a bit and the radio officer showed me how to fill out the weather report each morning as it was sent out over the Pacific by the marine weather reporting services (whereever they were, I can't remember). So, I would sit in the radio operators chair, dial up the frequency on the receiver, and copy the CW weather broadcast. I made a few mistakes at the beginning until I got use to the format and content. After that, each morning I had the job of copying and writing up the weather report for our area (pacific northwest coastal areas). I also learned a lot about navigating, taking sitings, plotting the charts, and I even spent an hour at the helm trying to sail a straight wake -- definitely a learned skill I did not totally learn. 73, phil, K7PEH > On Nov 13, 2017, at 9:23 AM, Eddy Avila wrote: > > Guys, I'm old enuf when CW testing was required by the FCC for any license grade.

I'm probably one of the young guys here, at 60. I made it to 5wpm and got my Novice, but never got past 10wpm. Took the general written to get my Technician, and when the 13wpm requirement was dropped was "grandfathered" to General. I currently hold an Extra Class license. Going back to my Tech. days, I never fell in love with code, spent a bit of time on 2m FM, but very early got into RTTY. Ran autostart on the SDTS repeater on 220 with a model 15 and later a 28KSR. Was a TAPR beta tester, and probably still have my BETA TNC. I like PSK-31. So, when the CW vs. Phone arguments crop up, my response is pretty much always going to be NEITHER! 73 -- Lynn On 11/13/2017 10:04 AM, Edward R Cole wrote: > The purpose of requiring CW was perhaps not to be restrictive - but it > had exactly that effect.

Anyone who remembers the "incentive licensing" debates of the mid-60s knows the Morse requirement in the U.S. was clearly intended to be restrictive by many hams if not most. Incentive licensing intentionally took away privileges with a code speed requirement that persisted until the fairly recent no-code licensing. I've always been a cw op. I lived in Japan when I was 12 and heard hams talking on my SW-54. I had no interest in that at all until I learned about hams using Morse code. I've been 90%+ CW since. Definitely not by choice, but I took General, Advanced and Extra before FCC examiners in Boston and Long Beach.

I've been using WSJT-X since it was first introduced several years ago, and I've never had this problem. I've always used VOX to put the rig in TX mode, as I do with SSB and all digital modes. I've often run with a power amp that uses a vacuum relay for T/R switching, and there's sufficient delay within the K3 and K3s for the amp's T/R relay to switch. 73, Jim K9YC From tommy58 at hvc.rr.com Mon Nov 13 15:24:45 2017 From: tommy58 at hvc.rr.com (Tommy) Date: Mon, 13 Nov 2017 15:24:45 -0500 Subject: [Elecraft] WSJT-X K3/K3s hanging as Tx In-Reply-To: <00f001d35cbb$1142da30$33c88e90$@earthlink.net> References: <5A09EEA2.11250.416BA57@Gary.ka1j.com> <00f001d35cbb$1142da30$33c88e90$@earthlink.net> Message-ID: <1fbeb4cc-dd30-693b-5729-b73df641757d@hvc.rr.com> ?This happens to me once in a while however if I let it go through the cycle it shuts off TX and will be normal again next cycle with RF out.

BS! Many rigs have race conditions in their processors. *NEVER* use software PTT and stick to hardware (RTS) switching only - particularly if you have the need for external sequencers and audio switching. If you have a problem with hanging PTT with hardware switching, fix the common mode RFI issues in your shack! If you don't fix them now, they will bite you later (and somewhere you don't expect). 73, ...

I have a Flex 6500 with KAT500/KPA500 combo. It's been working great until very recently. Within the past couple of days I was intermittently reading high SWR when the amp is in operate. In standby or off everything looks good. As of last night it's not so intermittent. In receive when I switch from standby to operate I'm only receiving the strongest of signals. Everything else disappears almost like the antenna was disconnected. When switching between standby and operate I hear a relay clicking. I'm not sure but it doesn't seem to be as loud a click as I normally hear but I can't be sure. With the amp powered down and the Flex set to 100 watts out everything seems to be working fine.

Make sure the PL-259s are tight and if you can substitute the jumpers with known good ones - particularly the one between the KPA500 and the KAT500 and the one between your transceiver and the KPA500. There are as many problems caused by cables as are caused by equipment. Some cable problems have no apparent problem at lower power, but rear their ugly head at higher power. You could also have a higher power problem with your antenna. Switch to an alternate antenna or dummy load if possible (tune the KAT500 into the dummy load) as a test. 73, Don W3FPR On 11/13/2017 4:41 PM, Kevin der Kinderen wrote: > Waiting on an answer from Elecraft but thought I'd also check with the > group here. > > I have a Flex 6500 with KAT500/KPA500 combo.

You may be putting the performance of your station at a disadvantage with that approach, compared to using WSJT-X with CAT to keep TX audio in the range 1500-2000 Hz. The roofing filter may have a fair amount of group delay inequality at the edges of the passband, which can lead to inter-symbol interference on digital modes. I don't know how serious, if at all, this is in practice, but I know one very clever engineer who regards it as enough of a problem to have had a custom roofing filter manufactured for his K3 to reduce it. He mainly works EME with JT65. 73, Richard G4DYA From donwilh at embarqmail.com Mon Nov 13 18:10:12 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 13 Nov 2017 18:10:12 -0500 Subject: [Elecraft] WSJT-X K3/K3s hanging as Tx In-Reply-To: References: <5A09EEA2.11250.416BA57@Gary.ka1j.com> Message-ID: <50e93064-d022-c1d4-ae37-f4091e8f89d9@embarqmail.com> Richard and all, The proper place to cure "RF in the shack" problems is in your antenna system. A good common mode choke (many call it a balun) in the antenna feedline and running the feedline at right angles to the radiator (assuming a dipole) to keep the feedline from picking up radiation from the radiator. If that physical configuration cannot be avoided, then an additional common mode choke at the shack entry point can help. In the case of off-center fed antennas and end-fed antennas, often the common mode current on the feedline can be difficult to cure. Use of one or more of the effective "baluns" described by Jim Brown K9YC at http://audiosystemsgroup.com/RFI-Ham.pdf will help. With effective common mode chokes on the antenna and feedline, you should not have to use ferrites on every cable in the shack - a much more sane answer IMHO. 73, Don W3FPR On 11/13/2017 5:46 PM, Richard Lamont wrote: > On 13/11/17 19:12, Gary Smith wrote: > >> For those using WSJT-X, sometimes I find >> the K3s is locked as transmit but there is >> no RF being sent and no Rx from the K3. >> >> Anyone experience this and figure out how >> to prevent it? > > I've seen this occasionally too.

If, for example, equipment in the shack is not properly bonded together, an antenna close to the shack will put a lot of RF in the shack, which will induce RF onto cables connected to equipment, and is likely to couple into equipment. If an antenna is working as an antenna and it's close to the shack, it WILL put RF in the shack -- that's what it is intended to do!

After changing diode (and checking associated bits I has problems with power/dissipation on 10 and 6m cured by using a diode from a different batch. However, after re-assembly I had intermittent lack of RX, traced to a relay card used externally for buffering a relay. At the time this board was unpowered but still in circuit and was holding the KPA500 on TX. A simple bypass proved it was the culprit and putting its 12v power back on fixed it for good. -- Brian D G3VGZ Yarm England From ch at murgatroid.com Mon Nov 13 19:32:56 2017 From: ch at murgatroid.com (Christopher Hoover) Date: Mon, 13 Nov 2017 16:32:56 -0800 Subject: [Elecraft] WSJT-X K3/K3s hanging as Tx In-Reply-To: <97d1523e-0233-5448-7b91-f60411f91070@lamont.me.uk> References: <5A09EEA2.11250.416BA57@Gary.ka1j.com> <54c23fba-24e0-d33b-782e-623916d30bee@audiosystemsgroup.com> <97d1523e-0233-5448-7b91-f60411f91070@lamont.me.uk> Message-ID: > > > The roofing filter may have a fair amount of group delay inequality at > the edges of the passband, which can lead to inter-symbol interference > on digital modes.

What I have found is For example, on the k3, it will change modes before it changes bands. The result, when you are on the new band you are in the wrong mode.?On the Yaesu ftdx radios, it puts the radio into USB instead of data mode for transmit, and rtty mode for receive. It does not handle split correctly on the ftdx radios either. This is more important for yaesu rigs because they can have per mode parameters for gain and so on.?It is quite possible it is doing something wrong when it comes to Dtr control.?On the other hand you can try to use the omnirig entry in wsjt x for control, but it also has mode issues. Not sure about the k3. That may work better.?73 Tom?

Even the K3 PTT to RF delay is not sufficient to accommodate switching delay in old amplifiers, EME sequencers or the LNA/preamp bypass relays for external (active) receive antennas. > Are all those having a similar problem using MicroHam something? or > does it occur with other interfaces. It occurs with other manufacturers products and CAT PTT - nearly every manufacturer has a race condition in their controls when CAT and hardware are mixed.

I am a novice at WSJT-X but I can't help but feel that it is a program that is genius but immature. I say this expressly because I run N1MM, MMTTY, logic 9 and my GPSDO all with LP bridge but WSJT-X wants to have total dominion over the operating system as far as the ports go. I have found a way to finagle it to work with LP bridge but not because WSJT-X has any interest in that being the case. Considering how many people are having trouble with ports and that program, it seems like the problem to me is within the program itself and how it approaches using ports. If the other programs can use the virtual ports without issue, it doesn't make sense that WSJT-X has to have dominion. I'm sure that after enough complaints and enough time, that the authors will attend to this problem. It is only when I use WSJT-X that I have the issue that I mentioned in my initial post which is hanging of the transmit function without sending RF out the antenna. No other program or situation causes this to happen, only WSJT-X so as far as I'm concerned it is a buggy program but a genius program at the same time, what it does is amazing and it is free no less. My only interest in posting was to find if somebody has found a way of getting around this bug. When it comes to the idea of RF getting back in the shack, I never get any RF back in the shack to disturb anything when I use my antennas that are almost 400 feet from the house using 1 inch hardline get to them. The only time I ever have any issue with RF in the shack is if I use the tri-band on top of the house and I rarely use that because of RFI in the neighborhood. For this transmit-state issue to happen when I am running barefoot to an antenna almost 400 feet away which is tuned beautifully and I need no transmatch and me running barefoot... it is not RFI in the shack causing this problem. I do lay it squarely on the shoulders of the WSJT-X software for it never ever happens at any other time then when I am running this specific software. I really don't want this topic to run to the point that it becomes something Eric has to shut down so maybe it's best just to leave it and I will keep pushing a button on the front panel to unlock the transmit condition when it engages when WSJT-X goes rogue. The only way I can reproduce the problem every time ( And FWIW, PTT-Key is set to off-off) is to go into the WSJT-X settings, select Radio, click on test PTT and it creates this exact condition. If I exit settings without clicking on Test PTT again to shut the state off, the K3s is then left in this transmit state with no RF being made. The solution is to tap a button on the K3s front panel and all is fine again. The problem appears to me to be a still buggy WSJT-X issue that the authors have not yet become interested in attending to. I would just like to know how to have a workaround to get around this error until they fix it. As it is it has become tiresome. 73, Gary KA1J > For those using WSJT-X, sometimes I find > the K3s is locked as transmit but there is > no RF being sent and no Rx from the K3. > > Looking at the P3 I see a jitter on the > upper half of the screen as if there was a > tiny output but no Rf is seen on any of > the three SWR meters in line (K3s, AP3 & > LP-100A). > > I couldn't get WSJT to receive, looked at > the settings, all were correct and as is > sometimes needed with WSJT-X, I rebooted > to get it to work properly but it still > did not lock onto the K3s frequency. > Rebooted again and then I realized the K3s > was in that TX condition with both the red > & yellow LEDs lit and that jitter on the > P3 upper screen. > > This happens every so often and what I > have to do is touch any of the buttons on > the K3s and it disengages this situation. > I did that to deal with the issue I > mentioned above.

In standby, radio showing 1.25:1 SWR KPA500 remote reported Power: 18 w (that's typical) SWR: 1.1:1 Current: PTT OFF (typical in standby) Voltage: 74.8 Temp: 22 C Switched the amp to operated, radio still at 20.

That's because "Test PTT" in WSJT-X is a *TOGGLE* exactly like the XMIT button on the front of the K3. By clicking "Test PTT" only once, you are placing the K3 into transmit and *NEVER* switching it back to receive! WSTJ-X and the K3 are both doing *exactly* what you told it to do. > The problem appears to me to be a still > buggy WSJT-X issue that the authors have > not yet become interested in attending to. WSJT-X is not buggy. The radio control interface does not handle asynchronous data and it was not designed to do so. That means you *must* disable AI1; (set AI0;) in the K3 command (no automatic information reports) and *MUST NOT* share control of the K3 with any other software - where that software will poll the K3 and cause it to generate any unexpected data to hamlib (the WSJT-X control module). Your complaint really belongs on the WSJT-X list and not the Elecraft list. 73, ...

There is something unique to WSJT-X that no other software does that makes this happen, I only find it randomly if I am using WSJT-X. Never experienced it before WSJT-X and never with any other situation/software. > > > The problem appears to me to be a still > > buggy WSJT-X issue that the authors have > > not yet become interested in attending to. > > WSJT-X is not buggy.

The others share control as in N1MM and MMTTY, Logic & FLDigi working fine together. Logic runs beautifully with N1MM and MMTTY, no conflicts of any kind. If they can do this flawlessly, it is not unreasonable to expect WSJT-X to play nice as well. > > Your complaint really belongs on the WSJT-X list > and not the Elecraft list. ### I disagree. As is so often the situation when someone has an issue with Company A's product and Company B's product is being used and there is a conflict... the stock answer is that problem belongs to the other company, ask them what to do. It's an old saw and in this case, I'm told I should ask on the other list. Everyone feels it's the other guy's fault and that question belongs elsewhere. Ask there and they tell you how the K3 is non standard and to ask on the Elecraft list. The person in the middle gets trashed on both sides. I've experienced this for so long I've come to like trash. As I said in the words below, I was asking on the Elecraft list if others had experienced this problem. My original statement was: "Anyone experience this and figure out how to prevent it?" Where better to ask than a place devoted to this type of radio if others have the problem and if so, how to resolve it. When I first started with WSJT-X I asked on the WSJT-X reflector and was told quite clearly if I want to use it, I had to run it directly to the port for the K3, no other control software should be running at the same time and if I wanted to use logging I had to use JT Alert and have my logging done via that. I was also told virtual ports are nothing but trouble, not to use them with WSJT-X and there is no help for those that use them. It seems to me there's a lot of attitude on that list. FWIW, I did find I can use a virtual port with it # "10" If I assign any other numerical value it will not work. Won't work with Win 7, I tried for hours but with this computer & Win 10, WSJT-X works on virtual port 10. All the other software works on whatever virtual port I tell it to work on. WSJT-X is not yet user friendly, I suspect it will become more so over time. If I had the skills I would be happy to help make that so. My skills lie in other areas; want someone to help keep you alive following a traumatic injury? I can do that. Write software? I can't do that. 73, Gary KA1J > > 73, > > ...

I have a doublet, centre-fed with 300 ohm ladder line dropping vertically to a DX Engineering choke balun (which contains three binocular ferrite chokes in series). For good measure, I have a Fair-Rite #31 clamp-on ferrite on the co-ax next to it. The co-ax then runs in a duct buried about 350mm deep to the house, where it goes up the external wall and then through it about 4m above ground level into the (upstairs) shack, where there's another #31 clamp-on ferrite. > With effective common mode chokes on the antenna and feedline, you > should not have to use ferrites on every cable in the shack Well, my experience disproves your hypothesis. While common-mode current on the feedline is often a problem, it isn't necessarily the only problem. The problem here is radiated RF, not conducted RF, being picked up by the USB cables. It's only to be expected when the shack is in the antenna's near field. 73, Richard G4DYA From steve.steltzer at yahoo.com Tue Nov 14 07:19:46 2017 From: steve.steltzer at yahoo.com (Steve Steltzer) Date: Tue, 14 Nov 2017 12:19:46 +0000 (UTC) Subject: [Elecraft] RE : K3S RX antenna questions References: <932675664.1674945.1510661986731.ref@mail.yahoo.com> Message-ID: <932675664.1674945.1510661986731@mail.yahoo.com> Questions answered, thank you all! 73 and hope everyone has a GREAT day,Steve, WF3T From lists at subich.com Tue Nov 14 07:47:22 2017 From: lists at subich.com (Joe Subich, W4TV) Date: Tue, 14 Nov 2017 07:47:22 -0500 Subject: [Elecraft] WSJT-X K3/K3s hanging as Tx In-Reply-To: <5A0A6F3F.25562.60D1A6F@Gary.ka1j.com> References: <5A09EEA2.11250.416BA57@Gary.ka1j.com> <5A0A4E7B.8749.58D1F40@Gary.ka1j.com> <91bd63d5-6f27-f4f4-20c0-a8522e83fe89@subich.com> <5A0A6F3F.25562.60D1A6F@Gary.ka1j.com> Message-ID: On 11/13/2017 11:21 PM, Gary Smith wrote: > When I first started with WSJT-X I asked > on the WSJT-X reflector and was told quite > clearly if I want to use it, I had to run > it directly to the port for the K3, no > other control software should be running > at the same time and if I wanted to use > logging I had to use JT Alert and have my > logging done via that. Well, you got the best advice from the WSJT-X list - from the developers of that software. Why do you think the developers of the K3 and K3 users are going to tell you something different or fix a basic design decision in the WSJT-X software? *If you don't like the way WSJT-X operates, DON'T USE IT!* > I was also told > virtual ports are nothing but trouble, not > to use them with WSJT-X and there is no > help for those that use them. In the language of the WSJT-X list, "virtual ports" means port splitting software - not USB derived serial ports. Most port splitting software is a problem because it is nothing more than a software "Y" connection which causes exactly the kind of "unanticipated data" errors that crash the WSJT-X radio control. > It seems to me there's a lot of attitude on that list. The WSJT-X project has some of the smartest developers you will ever encounter. They have their own vision of the project and have no use for those who complain about the direction of that project unless the complainers are willing to contribute to the development *write code* of the features they seek. WSJT-X had its beginnings in WSJT which had no rig control and used only serial port RTS (or VOX) for T/R switching. CAT is present for only three purposes - 1) to shift TX frequency in order to center the TX tones; 2) for band hopping/scanning WSPR and 3) for split frequency meteor scatter work. None of those functions require cooperating with a logging program. What you want would turn a bicycle into a semi ... > ### WSJT-X is the only software I use that > does this.

N1MM & MTTY do not share radio control. Logic never polls the K3 and relies entirely on the auto-information or reading the data polled by other software. Logic & Fldigi (or other active control software) will bomb spectacularly with older Yaesu gear because both will try to poll simultaneously. Similarly, unless a logger makes provision to use MMTTY as a "RTTY engine" and MMTTY is configured to *NOT* do any control of the radio frequency or software PTT, MMTTY and most loggers will not coexist either. 73, ...

It will happen with 1 watt. It is a function of wsjt-x and may be related to using split. I have never seen the problem when NOT using split. The problem usually appears when clicking on a new station to answer a CQ, and the split has to change. The systems will return to normal in the next 15 second segment if nothing else is touched, or somtimes will return to normal sooner if the "halt tx" button is clicked on. I also see the problem when using other radios than the K3, I have an IC-7000 and ANAN-10E that also get used for wsjt-x. The problem has occured in wsjt-x versions 1.8 rc2, rc3 and release 1.8 I not remember seeing the problem before version 1.8 rc2, but can not be sure. I now have about 1,500 FT8 contacts in the log, so I use FT8 a lot.

The problem began when I had been using RCForb and a virtual serial port with CAT control of PTT for WSJT-X, so the explanation Joe offers makes sense based on my experience. Unless WSJT-X had some provision for reviewing all state changes to the K3 that might occur "unexpectedly" due to other CAT "clients" of the K3, it would not be able to guarantee that its own state matched that of the K3, which could seemingly result in the sort of behavior being experienced. 73, Matt NQ6N On Tue, Nov 14, 2017 at 8:07 AM, David Bunte wrote: > I won't take a lot of time weighing in on this thread.

The ACC1 cable from the KZPA100 goes to the PX3 ACC1 PC jack. The PX3 ACC1 XCVR jack then connects to the KX3 ACC1 jack. 73, Don W3FPR On 11/14/2017 1:33 PM, K.

Download WSJT-10 and see if your problems go away. WSJT-X is Joe Taylor's (with other developers) attempt to make WSJT usable for all bands and uses; it is fairly new and being revised to solve issues, so if you are a user (esp having problems) you might keep track if new versions have been released. HFer's esp seem to want to run all these loging and special control programs simultaneous with WSJT-X so should not be big surprise when they collide. I still run WSJT-10 for eme as its simpler and not trying to be all things to all users. I have downloaded WSJT-X and have it running on my K3 using audio line in/out and USB/RS232 adapter cable for computer I/F. I run two external soundcards which makes setting audio levels easier (has knobs instead of sliders). For VHF contests and eme paper logs is fine, and it gets transferred to a excel log (very simple chart), then I convert it to pdf. for posting on my website. I guess when you are working hundreds of stations per hour automation is handy. Recently MAP65 had a new upgrade which I downloaded before the recent EME Contest but I ran into a couple problems with very slow decoding and one window not opening (probably bugs which eventually will get fixed). I reverted to my earlier version to run the contest. I'm using an old XP32-SP3 computer so might be its being overloaded with the new sw applications (which expect you to run a Cray-4 or something). Adding some more memory might help me. Absolutely not upgrading to later OS newer hdwr as that will render much of my equipment obsolete (no drivers). A topic for another thread. One thing I see is that JT65 use on HF is very different than how its used on EME. Lends to "Beta-Max vs VHS like" compatibility issues. PS: several eme'rs are also having issues making WSJT-X work.

It can't transmit though. "So now I lost the feature to change antennas automatically when I change bands on the K3" Do you mean that you changed your connection back from the remoterig to your local equipment and that no longer works?

The Bandmaster III obtains band information from your K3 by sending commands that request it and decoding the replies from the K3.? That is, it's a 2-way communications.? When the Remoterig box is connected, it also sends commands and receives replies from the K3 ... also 2-way. I believe there may be a solution however.? The Elecraft KRC2 band decoder obtains band data from the K3 using the ACC port leaving the RS-232 CAT port free for the Remoterig.? The KRC2 would essentially replace your Bandmaster. [:-( This solution assumes that the KRC2 continues to produce band information for antenna switching when the K3 is connected to the Remoterig and in TERMinal mode.?

You must use 2 different COM ports. Otherwise, the K3 drivers and the RemoteRig drivers on the RS-232 connection will interfere with each other. If you do a study of RS-232 mark and space voltages, you will find that it is a point to point (one to one) communication. Other devices may "listen in" to the communications, but they must have all drivers disabled and set to a high impedance state. The K3 and the RemoteRig do not meet that criteria, so they cannot co-exist on the same COM port connection. The only solution is to use 2 COM ports (one for K3 and one for RemoteRig), and if they must synchronize, that will need to be done in the computer - but I don't know of any software application that will do that synchronization. 73, Don W3FPR On 11/14/2017 4:26 PM, Jorge Diez - CX6VM wrote: > Hello Fred > > I lost automatically antenna change because I needed to remove my CAT cable > from K3 to connect remoterig.

I was one of the six people responsible for the "No Code License". I consider it an honor to have been chosen as a member of the study committee by the ARRL. FWIW, each member of the committee was a dedicated CW operator. It had nothing to do with "incentive licensing". We were told by the both the FCC and the ARRL that some form of a code free license -was- coming and they wanted to give the amateur radio community a "say" in the matter. Our committee was widely publicized in the hobby's media and we all received -lots- of correspondence, both pro and con. I still have two cartons of letters in my attic. FWIW, the letters are about 50/50 in favor and against. What eventually became the "no code license" differs a bit from what was we proposed ... think 160M and 6M for example. It was thought that because of TVI that 6M would not be a good place to put inexperienced new hams and the lack of activity and LORAN A on 160M was a detriment. The jury will always be out on whether "no code" has been good for the hobby or not, but it was felt that the resulting increase in the number of licenses may have "saved" the hobby from the spectrum wolves on the prowl at the time. Trivia: We determined that if a person said they couldn't learn the code there was no way to disprove that. One can -always- find a CW QSO to enjoy. I've been essentially CW only since my Novice license in 1951 (WN5TKI) ... one of the first issued ... and the FCC only came to Oklahoma City once a year in those days. My SK Elmer (W5ADC) drove this 13 year old kid the 90 miles to take the exam. 66 years have passed ... such changes I've seen. 73! Ken Kopp - K0PP (Not a vanity call ... a story unto itself.)

Not only will Win4K3Suite let you share the CAT feed of your K3 with multiple software applications at the same time, but you can do it with physical serial connections too. Win4K3Suite connects to your K3's direct CAT/RS232 port and then manages the feed to other physical ports and or virtual RS232 port pairs for software connections. For example, I can have N1MM+, DXLab Commander and WSJT-X all sharing the CAT feed, each program follows the other if you want them all running at the same time... and beyond that I can setup another connection to my 2K-FA amp. In this example, all three software applications think they are directly connected to the K3. They all can poll the K3 data and they all receive the output data. The latest version of Win4K3Suite lets you setup up to 6 Aux/CAT ports for this purpose. They can be virtual com port pairs for software or direct connections to physical serial ports for an amplifier, SDA100, auto antenna tuner etc... It works very well and is rock solid reliable in my experience. I have a YouTube video that shows this... around minute 18 of the top of my head. In the quick demo in that part of the video I should the 2K-FA following the K3 along with a couple software apps, N1MM+ and DXLab Commander, if memory serves me correct. Jump to minute 18 a watch for a few minutes: https://www.youtube.com/watch?v=Ku8Gyl0amRY I'm assuming this is what you are looking for with your remote rig connection to your K3. You want the remote rig box to think it's directly connected to the K3 at the same time other software and hardware think they are directly connected. Win4K3Suite provides the best way to handle this IMHO and I have tried a number of solutions that will work too... LP-BRIDGE, Omni-Rig etc... but the other fall short when it comes to a transparent share across software and hardware. Max NG7M?

"Both antenna switch and Remoterig covet that single serial RS-232 port on the K3." The KRC2 can get band data from the ACC port leaving the RS232 open for the Remoterig.? Unfortunately, that solution makes his current antenna switch excess which may have other implications. So, rephrasing his question/problem:?

Win4k3 is not a comport splitter. The best way to describe it is that it provides multiple virtual radios to any number of applications or hardware devices.?It does this by being exclusively in charge of polling of the radio, and maintaining the state of the radio so that any other application that needs this information obtains it from memory and not from physical access to the radio port. The polling cycle has been optimized so that changes are almost immediate, and the complete api of Elecraft commands are queried for and cached.? If the application needs to write to the the radio, for example to change bands, it gets access almost instantly, by a locking mechanism that is part of win4k3. At that point the state of the radio changes and other applications have that new state.? Another area where win4k3 is different is that there can never be a race condition where excessive commands pile up in the radio command buffer. The response to commands sent to the radio are always a 1 to 1 event. There are never multiple commands sent and the the responses waited for. A single command is sent and then a response is waited for.?To date, there is not a single application that will in any way fail when connected to the virtual port facility in win4k3. You can run n1mm, nap3, wsjtx,? dxlab, and others simultaneously in full contest mode for days.?73 Tom? ? Sent from my Samsung Galaxy smartphone. -------- Original message --------From: "M.

You don't since you pass the computer connection through Bandmaster III using the USB input when the output is connected to the K3 RS-232 jack. You can not connect both the Bandmaster RS-232 connection *and* Remote rig to the K3 RS-232 jack at the same time. However, you can connect Bandmaster III to the K3 ACC jack and use the BCD data (Yaesu) to indicate the selected band. That will allow you to connect *either* Remote Rig *or* the local computer to the K3 CAT jack. Bandmaster will follow band selection from the rig whether you are using Remote Rig or the local computer. See the Bandmaster III manual and/or contact the manufacturer for support. 73, ...

Look at the RS-232 Specifications. The normal voltage for an RS-232 signal line is held at the "Mark level" of anywhere between -3 and -15 volts in its idle state (as measured at the receiver). A "Space" voltage is anywhere between +3 volts and +15 volts (again as measured at the receiver). The driver is a voltage source. So imagine 2 drivers trying to put a signal on a single receiver (or multiple receivers). The idle driver will be putting a negative voltage on the line, while the active driver trying to send data will be putting on a positive voltage. The resulting voltage will be unpredictable and depends on the impedance of each driver and the resistance of the signal line. What will happen if you connect two voltage sources (say 2 power supplies) together, one having a negative voltage and the other having a positive voltage. They will cancel one another (besides drawing a lot of current from both supplies). The net effect is that 2 RS-232 drivers on the same line will "fight" and proper communications will not be possible. RS-232 is a point to point operation. A single driver sending data to a single device. Other receivers may 'listen in' to the communications, but if 2 drivers are present on the same signal line, the result is chaos. Virtual ports can take care of that situation, but one cannot simply parallel live hardware RS-232 signals (with a "Y" cable or other means) and expect success, so hardware solutions are non-existent. This is a characteristic of RS-232 communications, and not a problem if you follow the rules. 73, Don W3FPR From vk5zm at bistre.net Tue Nov 14 21:45:25 2017 From: vk5zm at bistre.net (Matthew Cook) Date: Wed, 15 Nov 2017 13:15:25 +1030 Subject: [Elecraft] sharing K3 RS232 to CAT and Remoterig In-Reply-To: References: Message-ID: Jorge, You can reconfigure your Bandmaster III to use the Yaesu BCD band selector and get this BCD information off the K3 15-way Accessory connector. The downside is you will loose 60m and 75m as separate outputs. You'll need to make a new cable between the K3 15-way Accessory connector & BM III, page 10 of the BM III manual has the relevant info. If the 15-way connector on the K3 is used already, you can purchase a y-cable from Elecraft. 73 Matthew VK5ZM On 15 November 2017 at 06:53, Jorge Diez - CX6VM wrote: > Hello > > At my station, I have Elecraft K3, Bandmaster III, SixPack, CAT cable > connected to K3?s RS232 > > So when I change bands in the radio, antenna is selected automatically > through CAT cable and band decoder (Bandmaster III) > > Today I connected remoterig box, so needed to remove CAT cable to connect > remoterig. > > So now I lost the feature to change antennas automatically when I change > bands on the K3 > > How can I do to share RS232 to have CAT and remoterig at the same time? > > thanks, > Jorge > CX6VM/CW5W > ______________________________________________________________ > 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 vk5zm at bistre.net From w5jv at hotmail.com Tue Nov 14 22:33:56 2017 From: w5jv at hotmail.com (Doug Hensley) Date: Wed, 15 Nov 2017 03:33:56 +0000 Subject: [Elecraft] K3 / K3S Filters Available In-Reply-To: References: Message-ID: Still available for the K3 or K3s are: Two each 2.7 kHZ OEM SSB filters; list 139.95 sell 100.00 each; Two each 1.8 kHZ wide data filters; list 149.95 sell 119.95 each; Two each 1.0 kHZ wide CW filters; list 149.95 sell 119.95 each; The filters are less than 6 months old and hardly used.

RRC actually provides a built-in method to provide this duplicate CAT data. Since the RRCs' COM2 are already occupied to tie the two ends together using CAT, all you have to do is to change each RRC's COM1 to mode-7. This will duplicate CAT over COM1 and you can use it in for control. Each RRC will provide the CAT data separately, so you can run a CAT sync device such as SteppIR, amplifier, etc. on the radio side and a logging/control program on the control side simultaneously and independently. Also note that the baud rate on COM1 must not necessarily be identical with COM2. 73, Mitch DJ0QN / K7DX On 14.11.2017 18:04, Don Wilhelm wrote: > Jorge, > > You cannot have RemoteRig and the K3 on the same COM port.?

Not necessarily. One can successfully share a device like the K3 CAT port between two computers (or a computer and SteppIR controller, computer and Remote Rig box, etc.) by using isolation/steering diodes. The circuit is shown in the B&B Electronics 9PMDS/232MDS: http://www.bb-elec.com/Products/Datasheets/9PMDS-232MDS_2917ds.pdf The "modem sharing" device is not fool proof - it does not resolve the issues of both devices polling at the same time nor does it resolve the problem with "unexpected data" received by the inactive device but it does allow two devices to "share" a third under controlled conditions. Note: both "computers" will need serial ports that source at least +10V in the active state. Many newer USB to serial converters are 3.3V devices and the diode drop will reduce the active level at the shared device into the "undefined" range which can result in unreliable operation. 73, ...

The T1 manual indicates that you can manually initiate tuning remotely by pulling the ring of J3 to ground, so running an extra control line from the operating position to the remote T1 could work. It also details the protocol for sending band info to the T1 to recall the previous tuner settings on a per band basis. The special cable for the FT-817 uses this. The KX2 can be configured to send the current band out its serial port as a CAT command. I imagine one could build a device using an Arduino or similar to grab that CAT band data and send it to the T1 when requested.... Might be a fun project for someday.

Rapid rise and fall times of the DC voltage can generate RF spikes, and the collapse of the field in a DC relay if there is one at the business end can produce high instantaneous voltages back down to the rig end of the feedline. There are diode and capacitor-based circuit protections that can prevent this, but those phenomena were the prime suspects for why a remote antenna switch using DC inserted into the coax blew away the PA transistors and associated circuitry three times in a K2, until I trashed the switch. I can?t describe exactly what the protection circuits are, though as I recall they are pretty simple. Should be something in the archives about it from a couple of years ago.

I have noticed the same thing with mine although the issue does not appear to be the tuner itself, but the K3 is not transmitting any power so the tuner has nothing to work with. I am running FW version 5.60 an have this issue but only on 6 Meters. I can power up the K3 and open WSJT-X on my computer and select 6 meters which usually causes SPLIT to turn on. Hold TUNE and the TX keys and the display shows 0 power. Turn off SPLIT and it puts out power as usual. Then if I turn SPLIT back on, it will then output a carrier as usual. If SPLIT is enabled on 6 meters and you run a TX gain calibration, it will fail the calibration because the TX puts out no power. It's not a major issue but an annoyance since I tend to forget about it every time I switch from HF to 6 and try to check my antenna tuning.

RIT may be needed to fine-tune received signals even if the VFO itself is locked on a given transmit frequency.) Note: Coarse tuning steps for VFO A are set up per-mode using MENU:VFO CRS.

Available bandwidth settings are now 50 Hz, 150 Hz, 250 Hz, 350 Hz, etc. These are entirely adequate for virtually all operating purposes. > > > > > ______________________________________________________________ > 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 graziano at roccon.com From d.cutter at ntlworld.com Thu Nov 16 05:13:43 2017 From: d.cutter at ntlworld.com (David Cutter) Date: Thu, 16 Nov 2017 10:13:43 -0000 Subject: [Elecraft] DC insertion into antenna coax In-Reply-To: References: Message-ID: <1309348AA4634F2D9C05486D2E4B7ADB@DavidPC> Glad you raised that, Ted.

Just make the connections as indicated in the various manuals and you will have a "500 watt transceiver". The firmware updating for the KPA500 and KAT500 is separate from that for the K3S and P3, and those PC connections only have to be active for the firmware load. The PC connection for CAT control will be the same as you have now with the K3S and P3. 73, Don W3FPR On 11/16/2017 4:44 AM, Graziano Roccon wrote: > Ciao, > i own a K3s with P3 panadpter. > I would like to have a KPA500 and a KAT500 (here in Italy more a dream that reality, very hard to find). > > I am wondering if is possibile connect TOGHETER in some way and have all working as planned: > > - K3s > - P3 > - KPA500 > - KAT500 > - Computer connection for CAT control > > without re-work the connections for firmware upgrade, ecc.

The INFO 201 should be shown only once (and not in normal operation). It will be shown once after a Master Reset. It should finish in about 30 to 40 seconds. The first thing to check is the soldering on the Control Board. Reflow the solder adding a bit more (to add a bit of flux). Use a hot iron (750 degF) and dwell on each connection until you see the solder flow out onto the solder pad and the component lead - that should take about 3 seconds, but if it takes up to 5, no problem. 73, Don W3FPR On 11/15/2017 8:55 PM, Dan, K7DJK via Elecraft wrote: > Need some help here. > > Been working on my K2 S/N 7770 and got to the point where power is first applied. > > Upon pressing the Power button, got the INFO 201 message, but it just remained on the display.

We?ve added a ?TM? command to set the TX bar graph mode on the LCD. This also affects what is read in transmit mode by the ?BG? command (bar graph read). The syntax is: TM0; SWR/RF metering TM1; CMP/ALC metering Thanks to the TM command, BG can now read either the power level (with TM0 in effect) or ALC level (TM1). The latter may be especially useful for remote installations using FT8 or other audio-based data modes. Just to recap other remote-control commands added in recent releases: DEnnn; inserts a processing delay of 10 to 2550 ms (nnn = 001-255), useful for command pacing, especially in K-Pod macros ARn; RX antenna on (n=1) or off (n=0) If you?re interested in testing this field-test release, please email me directly. 73, Wayne N6KR From n6kr at elecraft.com Thu Nov 16 11:19:13 2017 From: n6kr at elecraft.com (Wayne Burdick) Date: Thu, 16 Nov 2017 08:19:13 -0800 Subject: [Elecraft] Beep In-Reply-To: References: Message-ID: This is definitely on the KX3/KX2 firmware task list.

(The original range was 3 to 20 minutes.) If auto power-off is not desired, set the menu parameter to INFINITE (default). > > * VFO A LOCK DISABLES COARSE VFO A TUNING WITH OFS/B CONTROL: This is intended to prevent accidental frequency changes due to touching the OFS/B control. As long as VFO A is locked, the offset-tuning feature will also be locked. (RIT, if used, is still *not* locked. RIT may be needed to fine-tune received signals even if the VFO itself is locked on a given transmit frequency.) Note: Coarse tuning steps for VFO A are set up per-mode using MENU:VFO CRS. The OFS/B control can be used to coarse-tune VFO A if RIT and XIT are both turned off and the control is not assigned to VFO B (?B? LED). > > * FILTER BANDWIDTH & ULTIMATE ATTENUATION FIX: Filter bandwidth settings ending in x00 Hz are now increased internally to x50 Hz to ensure excellent ultimate attenuation (stop band). For example, a setting of 400 Hz becomes 450 Hz. This is a temporary workaround for a DSP algorithmic issue with the x00 settings that will be corrected in a future release. Available bandwidth settings are now 50 Hz, 150 Hz, 250 Hz, 350 Hz, etc. These are entirely adequate for virtually all operating purposes. > > > > > ______________________________________________________________ > 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 graziano at roccon.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 hidron at hotmail.com From w5jv at hotmail.com Thu Nov 16 13:48:33 2017 From: w5jv at hotmail.com (Doug Hensley) Date: Thu, 16 Nov 2017 18:48:33 +0000 Subject: [Elecraft] 3rd Party Parts available for Elecraft K1 / K2 Message-ID: I have available for the K1/K2 transceivers: the K6XX CW Indicator with False Blink kit, LED Button Option & header connect/disconnect option.

I probably would have never noticed it had it not been for JT65 since WSJT-X always turns SPLIT on automatically and moves VFO B around depending on where you are on the waterfall.

Check where pin 1 is located and that is the IC side with the notch. Also check U8 for reversal, this could pull down the I2C lines to the EEPROM. Do this check also for U4 and U5 on the RF board, they also share the I2C lines of U6. Also check RP7-1/2 which is pulling down SDO on U7. As a last thing I can image, check if X2 is a 4MHz crystal and not completely detuned. If you do have a scope or external frequency counter handy it should show around 4MHz at U6-13/14. If none of this helps, U7 might be damaged. 73 Gernot DF5RF From donwilh at embarqmail.com Fri Nov 17 17:11:33 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 17 Nov 2017 17:11:33 -0500 Subject: [Elecraft] XV-144 -> redesign = XV-144-2 In-Reply-To: <002c01d35fc7$dceee250$96cca6f0$@biz> References: <008e01d35f0e$bfcbc620$3f635260$@comhem.se> <001b01d35f2a$a3d1fef0$eb75fcd0$@biz> <2FE80C11-692C-440D-8465-483B4FFCD9AB@Alphadene.co.uk> <002c01d35fc7$dceee250$96cca6f0$@biz> Message-ID: <2c695518-d3e9-8a9a-31b5-293f52bfda8e@embarqmail.com> Ron and all, The XV144 will not tune high enough in the 2m band to send FM. The 28MHz IF strip is not wide enough to do that with one Local Oscillator crystal. The K144XV switches crystals to allow the upper half of the 144 MHz band to be tuned. While it is true that the XV144 *could* transmit FM in the lower part of the band, that mode is not allowed (at least in the US) on the lower portion of the band, so DTMF tones would not be of use. 73, Don W3FPR On 11/17/2017 12:16 PM, Ron D'Eau Claire wrote: > > If you hook the XV144 to an FM transceiver with a DTMF generator it should pass the tones just fine.

I can use a coax switch to choose between the two Rx antennas but with the K3Ss/K3 with subRx I have the RX in/ant out and the Aux RF input for the SubRx. The manual is pretty straightforward but they don't have a block diagram for something like the K3s with SubRX / Diversity, using the Aux RX jack. DXE has it figured for most radios and I can set up the K3s like that as well, but has anyone using the NCC-2 figured the most effective way to get diversity and also best utilize the NCC-2?

What I want to do is using the SWT or SWH codes is to press and hold the rec button on the radio which will switch memory bank to two, push the M1 button to play the recorded voice, and then switch the memory bank back to one. This is the code I have so far. F5 Prec,{cat1asc swh37;}{cat1asc swt21;}{cat{cat1asc swh37;} What I had found though was that N!MM spits out the code too fast and the K3 does not have enough time to finishing processing the first cat1asc command. Clearly I will need a delay between each of the three "cat1asc" codes so that the K3 will process each cat command and then be ready to accept the next command. So the question is; does the K3 have a method to introduce delay that I can use on the N1MM function key string of commands so that the K3 can process each command or does N1MM have a way to process each separate cat command in a function key using a delay command of N1MM making? So if there is a solution, it may lie with either N1MM, Elecraft or both so I am posting to both lists.

It provides among other useful things message memories with embedded serial number incrementing. That feature is, surprisingly to me, missing from Elecraft?s onboard keyers. It?s called the Ultra PicoKeyer Kit and is available from hamgadgets.com. Works very well, intuitive interface, clear operating instructions and very small size. Inserts right in the keying line with 3.5 mm plugs. I have no interest in hamgadgets. Just passing this along.

What I want to do is using the SWT or SWH codes is to press and hold the rec button on the radio which will switch memory bank to two, push the M1 button to play the recorded voice, and then switch the memory bank back to one. This is the code I have so far. F5 Prec,{cat1asc swh37;}{cat1asc swt21;}{cat{cat1asc swh37;} What I had found though was that N!MM spits out the code too fast and the K3 does not have enough time to finishing processing the first cat1asc command. Clearly I will need a delay between each of the three "cat1asc" codes so that the K3 will process each cat command and then be ready to accept the next command. So the question is; does the K3 have a method to introduce delay that I can use on the N1MM function key string of commands so that the K3 can process each command or does N1MM have a way to process each separate cat command in a function key using a delay command of N1MM making? So if there is a solution, it may lie with either N1MM, Elecraft or both so I am posting to both lists.

I've replaced all RF cables including the one out to the BALUN and the BALUN itself. I know which bands are less than 10:1 in bypass and locked out bands that exceed that SWR. Something in the amp just refuses to switch from straight through (standby) to amplified (operate) and the radio sees infinite SWR with the KPA500 in operate mode. Elecraft had me check one resistor that might cause the problem and said further troubleshooting would have to be at their facility. While I'm trying to dig up some schematics to help out I'm getting the feeling it will be on its way back to E for service shortly. In the meantime, I got comment about how I run my KAT500: "KAT500 - We normally leave the KAT in the MAN position, not AUTO. With varying SWR, the KAT will tune while in transmit when in the AUTO position." I'm not quite sure what that to make of that. I have my KAT500 in the AUTO position thinking it's a good thing that the KAT will tune if something happens... which it never does. But in AUTO, at least the tuner will retune if I jump to a frequency that is not in memory. In MAN mode, I have to initiate tuning myself. Why would I not want to let the auto-tuner auto tune? 73, Kev K4VD From donwilh at embarqmail.com Sat Nov 18 15:12:56 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 18 Nov 2017 15:12:56 -0500 Subject: [Elecraft] KAT500 Auto or Manual In-Reply-To: References: Message-ID: Kev, Put the KAT500 in AUTO mode and then let it autotune with a constant CW signal (the ATU TUNE will produce the right signal) every 50 kHz across each band of use and for each antenna. Then switch it to MAN mode. The "problem" is mostly in SSB mode, but can also occur in CW mode. The reason is that the forward power cannot be measured simultaneously with reverse power. Lets say you are in SSB mode - due to the syllabic nature of speech, there will be times when the power is high and times when the power is low. If the forward power is read during one of the times when the power is low and the reverse power is read when the power is higher, it will compute to a higher than normal SWR and the tuner will begin a retuning cycle if set to AUTO. 73, Don W3FPR On 11/18/2017 2:41 PM, Kevin der Kinderen wrote: > Hi: > > I'm the one that recently reported problems with the KPA500.

The radio sees infinite SWR when the amp is in operate mode. The radio sees good SWR when the amp is in standby mode. [FLEX] --> [AMP] --> [DUMMY LOAD] When the amp is in standby the Flex shows good SWR. When I switch the amp to operate the Flex shows infinite SWR. It's as if I just disconnected the coax when I switch to operate. The amp shows no indication power is reaching it yet it must be if it goes through the amp in standby mode. So I think it has to be how it is switched within the amp. Same symptoms if I replace the dummy load with: [FLEX] --> [AMP] --> [TUNER] --> [ANTENNA] As long as the amp is in standby the radio is happy and I can make QSOs (Guinea-Bissau a few minutes ago). But when I switch the amp to operate, the radio shows maximum deflection on the SWR meter and there's no indication from the amp or tuner that RF is making it that far. These symptoms persist even after replacing all the coax (jumpers between equipment and between tuner and BALUN (tried each of DXE-BAL600H10A, DXE-BAL200H11CT, DXE-BAL050H11CT). Also no help when I switch from the dipole to the Hex on 20. Has to be the amp and it is like the amp switches from standby to limbo (open). I considered tapping lightly with an 8 lb hammer but maybe that's not a good technique. ;) Someone had suggested checking the PIN diodes. I'm looking over the schematics I could find on the Internet. They are a little help though the don't seem to be consistent. On the LPF schematics there's a control signal *[TR Switch>* but I can't follow that back to the origin of the control signal. The other obvious place to look is K23/K24 on the TR Switch schematic. The control signal here is *[BYP> *but again I can't figure out the source of the signal yet. The schematics were just found on the Internet and dated in 2011 so I can't even be sure I'm not using something too outdated. 73, Kev K4VD On Sat, Nov 18, 2017 at 3:30 PM, James Wilson wrote: > This is a puzzle.You say the Amp sees infinite SWR ? > > Do you have a dummy load?

Most of the higher frequency bands [40 thru 15] have 50 KHz bins. 12 and 10 are 100 KHz, and I believe 6 is 200 KHz.? So, to "train" your KAT500: 1.? AUTO mode.? Tap ATU TUNE to make it tune 2.? Start at the center of the lowest bin for the band [3510 for 80] and tune 3.? QSY up the bin-width for the band and do it again. 4.? You need to do this for each antenna you have for a given band. Using the KAT500 Utility, you can designate one of the three antenna connectors the default for each band.? You can also lock out connectors for each band, and they will be skipped when manually selecting antennas on the front panel.? It takes awhile but once you do it, you're set.? I found that some bands needed a little tweaking between summer and winter but that's all. You want to operate in MAN mode.? The tuner can't measure SWR on other than a continuous, steady signal.?

No asterisk I'm using a Flex 6500. I have the Flex's TX1 line connected to the PA Key of the KPA. For some reason, the Flex's TX1 was set to disabled. Dang software control! DDUtil is supposed to automatically set that for me I think. Still with the test setup - rig -> amp -> dummy load after I manually enabled TX1 I got good power out of the amp.

It is not unusual that a coax jumper (or antenna feedline) to seem to work at lower power, but can breakdown at higher power levels, particularly from a shield that has almost pulled away from the plug. Also, make certain the PL-259 connectors are tight - snug them down a bit more with pliers. 73, Don W3FPR On 11/18/2017 4:33 PM, Kevin der Kinderen wrote: > Thanks everyone for helping me understand the right way to use the KAT500. > I could have sworn I was doing the right thing by keeping it in auto.

G3: DE (Command Processing Delay; SET only; K3/K3S only) SET format: DExxx; where xxx is 001-255, the delay value in 10-ms increments. This is useful in switch or Kpod macros, where a delay may be desired to allow the radio to complete a previous operation before the next command is processed. Note: DE001 may result in a delay shorter than 10 ms, while DE002 is guaranteed to provide a delay between 10 and 20 ms (etc.). This was introduced in firmware version 5.60, so you may need to update your firmware in order to be able to use it. However, before using it you should also take note of the following, from the N1MM+ manual's description of the CAT1ASC macro: You can not place more than one CAT1ASC or CAT2ASC macro in a message but the message can contain one of each macro. The exception to this rule is when the {END} macro is used. More than one radio command can be sent to the radio by either placing a \ character between the radio commands or by concatenating them together. Spaces before or after the \ character are sent to the radio. Multiple radio commands using the \ separator are broken into individual radio commands and sent to the radio using internal command pacing. In other words, if you want to execute a series of radio control commands from a single N1MM+ function key, you should place them all in a single CAT1ASC macro. They do not need to be separated by anything other than the ; command terminator, in which case they will all be sent to the radio at once -- or, if you place a \ between two commands within a CAT1ASC macro, N1MM+ will send them to the radio in separate polls. I'm not sure what the polling rate is, but note that you have some control over it - there is a control in the radio control port setup dialog that allows you to select slower polling rates (505 slower or 100% slower). Perhaps some experimentation with the \ separator and/or the DEnnn; command will let you put the first bank switching and message sending command together into one function key message. The second bank switching command could be more of a problem, as the required delay may depend on the length of the message. Note also that when you use the radio's voice keyer, N1MM+ has no way of knowing how long the message will take. This may lead to undesirable side effects. If any of these side effects is unacceptable, the solution will be to use N1MM+'s own digital voice keyer instead of the DVR messages in the radio. 73, Rich VE3KI From jim at audiosystemsgroup.com Sat Nov 18 17:15:39 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 18 Nov 2017 14:15:39 -0800 Subject: [Elecraft] KX3 Field Ant. for 80/40/30 In-Reply-To: References: Message-ID: <9932fc1a-3e21-2725-db18-50876277c969@audiosystemsgroup.com> On 11/18/2017 1:34 PM, JT Croteau wrote: > Friends, what would be a good end fed wire setup that will match well > with the internal KX3 ATU and cover, hopefully, 80, 40, and 30 meters? > > I went out to my winter camp site, with two really tall pine trees, > and tried to experiment with a 9:1 UNUN, 135' radiator, and 35' of > RG8X. The ARRL Handbook and ARRL Antenna Book are your friend. If you don't own them, RUN to your computer and buy one, new or used. The short answer to your question is that, in general, end-fed wires need a counterpoise to work well. For your situation, I'd build two end-fed center-fed dipoles, one for 80 and one for 40, launch one into one of the trees, the second into the other tree. 75 ohm coax is the best match to these antennas, but 50 ohm coax will work. The following slide show describes this technique, beginning on slide #70. http://k9yc.com/VerticalHeight.pdf If possible, rig your dipoles so that they slope away from the tree(s) in which they are mounted. Anecdotal reports, and my limited experience, say that trees absorb a bit of the RF from a wire very close to their trunk. I suggest that you pull both antennas up as high as practical. If for some reason you don't want to rig a dipole like this, pull a quarter wave wire for both bands into those trees and rig a quarter-wave counterpoise for each that's at least 6-8 ft above ground. If a feedline is needed, use RG8X with a good common mode choke but no transformer. 73, Jim K9YC From jt.tobit at gmail.com Sat Nov 18 17:20:06 2017 From: jt.tobit at gmail.com (JT Croteau) Date: Sat, 18 Nov 2017 17:20:06 -0500 Subject: [Elecraft] KX3 Field Ant. for 80/40/30 In-Reply-To: References: Message-ID: Thanks Don, I will try this next.

Feet is not my everyday system for length measure, but i think it transelate to very close to an full wave length on 40m and close to an half wave on 80. That is an tough match for any tuner. Even so, with the transformer and the coax I think it should have given better results than 6.4:1 on most bands. Did you have an choke between the coax and the radio/tuner? That might be worth a try. Also I would look for malfunction somewhere. BUT. To answer your question. My go to antenna for the lower bands is an simple dublet, feed with some old army field telephone wire. It's an twisted pair of multi strand wire. I belive it has four strands of copper, ant three stainless steel, but I might be mistaken. The dublet is 2x20 ( aprox) meters. Might be worth a try.

One suggestion though -- there's RF current in the counterpoise, and having it too close to the ground will burn (waste) some TX power. Better to run it in the range of 6-8 ft. Remember - an SWR indication at the rig is NOT an indicator of antenna performance.? It only tells us that the transmitter is matched to whatever is connected to its terminals, but it tells us nothing about how much power is LOST in the feedline, the antenna, or the ground, nor does it tell us how well the antenna radiates or in what directions (vertically and horizontally) it radiates. 73, Jim K9YC On 11/18/2017 2:05 PM, Don Wilhelm wrote: > The easiest end fed antenna for portable use with those bands on the > KX2/KX3 comes from some experiments and experience of one of the KX2 > field testers (and an active SOTA ham). > Use a BNC to dual binding post (Pomona) adapter on the KX2/3.

Many operators "train" their KAT500 as Don described, tuning at least once in each segment across all the bands you use so the KPA500 will memorize the L and C settings. That avoids being surprised by an "auto-tune" occurring after a quick QSY while running contests, etc. The number of memory segments vary according to band as follows: Below 3 MHz the segments are 10 kHz wide. >From 3 MHz through 26 MHz the segments are 20 kHz wide. >From 26 MHz to 38 MHz the segments are 100 kHz wide. >From 38 MHz to 60 MHz the segments are 200 kHz wide. Normally you won't need to do a TUNE in every segment. That depends upon how fast the SWR changes with frequency with your antennas. Once the KAT500 memories are loaded across the bands you use it will not need to retune. I leave mine in AUTO knowing that if I'm ever surprised by a tune sequence starting, it's because something has gone wrong with the antenna or antenna switching that I need to know about immediately. In the meantime, my QSO only has a short interruption and I can explain to the other station what happened. Putting the KAT500 in MAN will mean that if anything goes wrong causing an excessive SWR, your KAT500, KPA500 will fault or your the transceiver driving it will shut down instead. 73, Ron AC7AC -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Kevin der Kinderen Sent: Saturday, November 18, 2017 11:41 AM To: Elecraft Reflector Reflector Subject: [Elecraft] KAT500 Auto or Manual Hi: ...

I've replaced all RF cables including the one out to the BALUN and the BALUN itself. I know which bands are less than 10:1 in bypass and locked out bands that exceed that SWR. Something in the amp just refuses to switch from straight through (standby) to amplified (operate) and the radio sees infinite SWR with the KPA500 in operate mode. Elecraft had me check one resistor that might cause the problem and said further troubleshooting would have to be at their facility. While I'm trying to dig up some schematics to help out I'm getting the feeling it will be on its way back to E for service shortly. In the meantime, I got comment about how I run my KAT500: "KAT500 - We normally leave the KAT in the MAN position, not AUTO. With varying SWR, the KAT will tune while in transmit when in the AUTO position." I'm not quite sure what that to make of that. I have my KAT500 in the AUTO position thinking it's a good thing that the KAT will tune if something happens... which it never does. But in AUTO, at least the tuner will retune if I jump to a frequency that is not in memory. In MAN mode, I have to initiate tuning myself. Why would I not want to let the auto-tuner auto tune? 73, Kev K4VD ______________________________________________________________ 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 fcady at montana.edu From wes_n7ws at triconet.org Sat Nov 18 18:25:22 2017 From: wes_n7ws at triconet.org (Wes Stewart) Date: Sat, 18 Nov 2017 16:25:22 -0700 Subject: [Elecraft] KAT500 Auto or Manual In-Reply-To: <93970ba4-b750-c890-52ce-a254351be78d@foothill.net> References: <1828d63e-83a1-a6ce-2764-dfd00bf88338@foothill.net> <0f5045d5-c703-b025-0bc3-77ffa5fd61f2@triconet.org> <93970ba4-b750-c890-52ce-a254351be78d@foothill.net> Message-ID: The guys who think you can't work DX without a second receiver will get a kick out of this, but I don't have one and sometimes resort to using the "REV" button to listen on my split TX frequency.?

When I look closer I see two different popular approaches. The first uses a 9:1 impedance transformer in combination with a wire length that is not resonant on any band. The idea is that (assuming there is no significant feedline length) you have a medium impedance (450 ohms) on the antenna side of the transformer, and because the wire is not resonant so you might have an impedance into the wire that is also "medium". By adjusting the wire length, you might get pretty close to 450 ohms on one or two bands, and with a wide range tuner you can probably get below swr 2:1 for the radio PA to see. The second approach, used by MyAntennas and others seems to use a transformer with much higher impedance ratio. One way to construct such a transformer would be to cascade two 9:1 units for an effective ratio of 81:1. This would mean the wire should present an impedance of 4000 ohms or so. Another way would be using a single tranformer with a higher ratio. The impedance ratio is the square of the turns ratio. With a turns ratio of 9:1 you should again get to about 4000 ohms. Somewhere I saw somebody using an 8:1 turns ratio for an ideal antenna wire impedance of about 3200 ohms. These impedance levels are achieved by using a resonant wire. I don't know how you arrived at your parameters, but your wire length is too close to resonance on 80 and 40. Your transformer ratio wants a non-resonant wire, so you might see better results if you shorten the wire significantly and keep using the KX3 ATU. Alternatively, you could replace the transformer for a much higher impedance ratio, in which case you can probably operate with the tuner bypassed at least on 80 and 40 with a well adjusted wire length. With this approach you want the wire resonant on each band. It should be easy to achieve resonance on 80, 40, 20 and 10. As you double the frequency, you are changing the number of half wavelengths covered by the wire; the end feedpoint is always at the end of one of these half wavelengths, and thus you get the very high impedance that you seek. 30 meters does not fit as clearly into this scheme. The commercial versions use a small coil in the wire located close to the transformer end, and seem to be able to achieve a reasoable match for all the bands 80 and up without using a tuner. Now if you had placed the feedpoint in the center you would not have been able to get this consistency of feedpoint impedance from band to band. As I see it, this is a major reason for the popularity of the end-fed approach as contrasted to the conventional center-fed approach. Note that the 30m coverage of the 80 meter and up design is not replicated if you try the same approach with half the wire length. In this case you will need a tuner to get reasonable swr on 30. An important consideration is antenna height. We all know that antennas usually work better when placed higher. Looking a bit closer, we can look beyond the general installation height and consider the height(s) of the antenna part(s) that carry the most current. Antenna modelling may calculate the field as resulting from current levels in different individual pieces of the wire, and then it makes sense to elevate those portions more than other parts of the wire that carry less current. Another reason for this is the effect of ground losses. Jim Brown, in his article that he just linked to, shows that ground losses get worse the closer a vertical antenna is to ground. This makes sense as currents in the lossy soil are caused by induction from currents in the antenna. When we look at the current distribution within the vertical antenna wire it again makes sense to place the part(s) of the wire with high current higher rather than lower. One of the simplest portable antennas is a short wire or whip of a quarter wave or less. It will have a low feedpoint impedance that can probably be matched reasonably without a tuner or with a limited-range tuner. However, with a low impedance comes a current maximum at the feedpoint. This often means close to the ground, so even with a good set of elevated radials, considerable ground losses could be expected. (An actual connection to the soil would generally be much worse, unless you bury a lot of wires.) With a longer wire (1/2 wavelengh at the lowest band) we can have a very high feedpoint impedance, very low feedpoint current, and more elevated location(s) of high curent portion(s) of the antenna, for lower ground losses. Any antenna feed point needs to provide two terminals for the feed current to flow through a complete circuit. A end-fed designed for medium to high feed impedance has small feed current. In practice this means that whatever is used as the counterpoise side can be small. The applies with a "medium impedance" design as discussed earlier, but it applies even more for a resonant end-fed with its tiny feed current. A short piece of wire may be used, but often not even that is needed, as the feed return current may flow on the transformer and feedline (if used), and even on the radio box. This is fine for QRP and maybe even medium power, as the current is small relative to the higher current higher up on the wire. However, at medium to high power, if matching problems are encountered, or bothersome RF around the rig, I would consider a small counterpoise wire to the high impedance side of the transformer, or experimenting with the length of the feedline, as the length of it matters when "counterpoise current" flows on the outside of it. I would not count on the impedance transformer to function as a common mode choke for blocking such RF current. You could place a separate common mode choke somewhere on the feedline, and move its position as a way to adjust the length of the effective counterpoise. Look up Jim's article on how to build an effective common mode choke. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of JT Croteau Sent: Saturday, November 18, 2017 2:34 PM To: elecraft at mailman.qth.net Subject: [Elecraft] KX3 Field Ant. for 80/40/30 Friends, what would be a good end fed wire setup that will match well with the internal KX3 ATU and cover, hopefully, 80, 40, and 30 meters?

No, unfortunately for the CW evangelists, they haven't been. The rumor that *is* being greatly exaggerated is that the US Navy is 'reverting to Morse' for its communications. There's no suggestion of this in the press release cited. What is happening is that the US Navy is *continuing* to train *intercept operators* to read Morse. That is all.

Use a BNC to dual binding post (Pomona) adapter on the KX2/3. Connect a 58 foot piece of wire to the red (center conductor) post, and a 23 foot "counterpoise" wire to the black (shield) post. The counterpoise wire can be run along the ground or laying on top of nearby bushes. Tie a rock or other throwing item to the end of the 58 foot radiator and get it up in the air - TUNE it and operate. No balun, no fuss, and the wire rolls up into a small ball for transport.

If the wire is near an odd multiple of 1/4 wave (1/4 wave, 3/4 wave, 1 1/4 wave) then the impedance will be low. If you're expecting a high impedance and you have a 3/4 wave wire, you may have trouble getting a match with a 9:1 balun. That's oversimplified, of course. The reason "pseudo-random" antennas around 53' are popular is that length isn't resonant on any popular ham band, and you can start making assumptions about how it'll work. 73 -- Lynn On 11/19/2017 12:22 AM, Erik Basilier wrote: > End-fed antennas have gotten popular lately.

It should be useful in some situations. However, the thread creator wanted coverage of 4 bands with one antenna, and my personal interest right now is also solutions that cover serveral bands without adjustments and compromises. With that as the goal, I see no theoretical reason to want center feed. Only by feeding at the end can you get approximately the same impedance for each band, without moving the feedpoint, for so many bands.

It would be interesting to compare side-by-side to make sure that the high-ratio transformer isn't lossy enough to hurt performance.) If you are looking at a single band, with a 1/2 wave vertical wire. The current distribution should theoretically be the same whether we feed it at the bottom or if we move the feed point to the center at the cost of 1/4 wavelength of additional coax plus the cost of the common mode choke (but there may be another justification to have the choke anyway). If one is willing to compromise the requirement of covering several bands with very good match, there is also the option of Off-Center-Feed, which can allow operation on several bands, but the match on most or all bands will be a compromise that likely forces the use of a tuner, similar to the situation with an end-fed with 9:1 impedance transformer. If you compare the OCF with the end-fed with 9:1 impedance transformer, it is not clear to me which one has the edge in practical use (assuming both have the antenna wire suspended and shaped similarly). For the OCF the results will depend on the selection of feedpoint, and for the end-fed there is room for a wide range of wire lengths that are non-resonant and should produce "medium impedance".

I'm unaware of any computer power supply that isn't a switcher, but for most 12 volt needs an analog supply should fix the problem. The only downside that I can see is weight; analog supplies can be a bunch heavier, but they are RF quiet. There some quiet switchers out there. You just need to do some research to discover those. One that is quiet is the Tentec. It is actually an Astron that Tentec did some work on. I think the one Elecraft sells is quiet. Bit, you really need to investigate before buying a switcher. 73, Barry K3NDM ------ Original Message ------ From: "rich hurd WC3T" To: "stan levandowski" Cc: Elecraft at mailman.qth.net Sent: 11/19/2017 7:31:48 PM Subject: Re: [Elecraft] (OT) - Unplanned Discovery >Wow. > >Going to try that.

Unplug it and I don't hear noise.? The instructions that came with it specifically stated that the Kx33 should be placed the full length of the DC plug/cord away from the transceiver.?

My post is not a complaint about the Kx33 mfgr, or the Samlex Corporation or anyone else.? Maybe it's my transceiver, maybe it's my equipment, maybe it's my utility service.....I'm not qualified to say or knowledgeable to analyze. I simply wanted to suggest to others in the Elecraft family that if they have "noise" it might be right under their nose and worth checking out vs. blaming propagation or the next door neighbor? ;-) P.S. -? My "noise problem" is about two years old and coincides with the purchase of my first switch mode power supply.? I had a perfectly good linear supply made by Astron but I deemed it too big and klutzy and dumped it.?

However, performance of an isolated component is less important than overall system performance, where the matching to antenna impedance as well as counterpoise current routing and losses all play in. After the component testing to qualify different transformers as having low loss, I am planning to test different versions of resonant and non-resonant end-fed antennas against each other in pairs. The resonant (very high impedance) versons will include different transformer ratios. I may even include versions where the impedance transformation is performed with a tapped, tuned parallel-resonant circuit, which is the classic approach from the Zeppelin days. I may also include a center-fed dipole (conventional, K9YC?, sleeve around coax?). To be able to compare antenna systems with potentially small differences, I am set up with a pair of WSPRLite transmitters that let me run both antennas simultaneously in synchronization. In this type of testing one obtains two overlaid graphs representing the two antennas under test, versus time. Each value shows a composite number based on s/n ratios at a number of different receiving stations. Over time, the two curves tend to cross back and forth against each other, but over a few hours one can see whether one tends to dominate over the other. Transmission frequencies will not be exactly the same, but the difference will be very small. When done in my back yard, both antennas in a test will be influenced by all kinds of metal structures around it, including my tower, power lines, metal in the house, and the other antenna under test. I will minimize the latter by erecting the wires at 90 degrees angle, with the feed points close together, so that I can always reach both transmitters at the same time to push the start buttons at the same time. My main method of compensating for interactions with metal objects will be to swap the matching/feeding systems while keeping the radiators and transmitters in place. I like to deploy wire antennas in the field on 24 ft masts, so I will use two of those for the testing and arrange the two wires as inverted vee?s. For reasons of space, I will not include 80 m, so the two wires will be in the 60+ foot range, except for the non-resonant version where 50+ feet are commonly used. For possible tests using center feed, I would use different arrangements that all resonate as ? wavelength on 40. By comparing two antenna systems at a time, each time taking the winner to compare with the next antenna, I hope to determine an idea of what works best for me in field use. 73, Erik K7TV From: donovanf at starpower.net [mailto:donovanf at starpower.net] Sent: Sunday, November 19, 2017 3:33 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KX3 Field Ant. for 80/40/30 Its easy to measure transformer loss by measuring the loss through a pair of identical transformers connected to back-to-back.

However, it did connect a couple dots in that I was at my brother-in-law's house operating on the battery whilst visiting. I remarked that the noise floor was very low and just attributed it to his QTH. Never connected the fact that perhaps it was just the local noise sources and I should be less concerned about QRM from the neighbors and neighboring rooms, and more about what I was feeding the rig and the other sources in the room. I will now be spending some time rearranging things to try this out and get my noise floor down even further.

An RF ammeter is a useful instrument for measuring the relative efficiency different types of matching networks feeding similar antennas. I'm well familiar with the simultaneous synchronized WSPRlite antenna performance analysis techniques, I developed the techniques that SOTAbeams implemented earlier this year! They work very, very well but a few things must be done to avoid significant measurement errors and biases: 1. The two antennas under test should be located within less than one wavelength of each other, otherwise independent selective fading becomes a significant source of measurement error. 2; Horizontally polarized antennas should be oriented end-to-end to each other to avoid significant parasitic interaction that washes out the other differences in antenna performance 3, Do not attempt to compare horizontally polarized antennas to vertically polarized antennas, independent selective fading becomes a significant source of measurement error that takes an extraordinary amount of data collection to overcome. Enjoy! 73 Frank W3LPL ----- Original Message ----- From: "Erik Basilier" To: donovanf at starpower.net, elecraft at mailman.qth.net Sent: Monday, November 20, 2017 1:51:47 AM Subject: RE: [Elecraft] KX3 Field Ant. for 80/40/30 I am well aware of that, Frank, and in fact I have multiple cores sitting here waiting for such measurements. However, performance of an isolated component is less important than overall system performance, where the matching to antenna impedance as well as counterpoise current routing and losses all play in. After the component testing to qualify different transformers as having low loss, I am planning to test different versions of resonant and non-resonant end-fed antennas against each other in pairs. The resonant (very high impedance) versons will include different transformer ratios. I may even include versions where the impedance transformation is performed with a tapped, tuned parallel-resonant circuit, which is the classic approach from the Zeppelin days. I may also include a center-fed dipole (conventional, K9YC?, sleeve around coax?). To be able to compare antenna systems with potentially small differences, I am set up with a pair of WSPRLite transmitters that let me run both antennas simultaneously in synchronization. In this type of testing one obtains two overlaid graphs representing the two antennas under test, versus time. Each value shows a composite number based on s/n ratios at a number of different receiving stations. Over time, the two curves tend to cross back and forth against each other, but over a few hours one can see whether one tends to dominate over the other. Transmission frequencies will not be exactly the same, but the difference will be very small. When done in my back yard, both antennas in a test will be influenced by all kinds of metal structures around it, including my tower, power lines, metal in the house, and the other antenna under test. I will minimize the latter by erecting the wires at 90 degrees angle, with the feed points close together, so that I can always reach both transmitters at the same time to push the start buttons at the same time. My main method of compensating for interactions with metal objects will be to swap the matching/feeding systems while keeping the radiators and transmitters in place. I like to deploy wire antennas in the field on 24 ft masts, so I will use two of those for the testing and arrange the two wires as inverted vee?s. For reasons of space, I will not include 80 m, so the two wires will be in the 60+ foot range, except for the non-resonant version where 50+ feet are commonly used. For possible tests using center feed, I would use different arrangements that all resonate as ? wavelength on 40. By comparing two antenna systems at a time, each time taking the winner to compare with the next antenna, I hope to determine an idea of what works best for me in field use. 73, Erik K7TV From: donovanf at starpower.net [mailto:donovanf at starpower.net] Sent: Sunday, November 19, 2017 3:33 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KX3 Field Ant. for 80/40/30 Its easy to measure transformer loss by measuring the loss through a pair of identical transformers connected to back-to-back.

While I haven't tried it, it would probably be very hard to build a pair of 9:1 transformers or a single 81:1 transformer with low enough stray capacitance to work on the higher bands.? It might work up to 40 meters, I suppose. The big advantage of a resonant end-fed half wave is that very little current flows in the ground system or counterpoise, so most of the power is going into the antenna.? While it is hard to match that high impedance with a non-resonant transformer, it is very easy to match with a simple L network.? The only reason the internal ATU in the KX3, etc., can't match it is that it doesn't have enough range.? (And for good reason.)? An external L network consisting of a tapped coil and variable capacitor will do it nicely. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From doug at w7kf.com Sun Nov 19 23:49:57 2017 From: doug at w7kf.com (Doug Smith) Date: Sun, 19 Nov 2017 21:49:57 -0700 Subject: [Elecraft] O.T.

Below my answers: >Radiation results from RF current flowing in an antenna. An RF >ammeter is a useful instrument for measuring the relative efficiency >different types of matching networks feeding similar antennas. Granted. I might want to add that to my plans. I know that the WSPRLite tolerates no more than 100 mW of reflected power, and to avoid accident risk I intend to set the transmit power to no more than 100 mW. I do not know how the units might fold back transmit power in a scenario where the SWR is good but less than perfect. For this reason I am planning to use a tuner whenever SWR is not very close to ideal. The location of the tuner would be wherever it would make sense to place it in field operation. If I add ammeters, they would be placed at the feedpoint, which should work well when I compare different impedance transformers using identical wires. If I compare to non-resonant wires or center feed, it would be hard to compare ammeter readings. > 1. The two antennas under test should be located within less than >one wavelength of each other, otherwise independent selective fading >becomes a significant source of measurement error. Interesting. You are saying that this applies even if the comparison is done over several hours? In my limited back yard, and because I want the feedpoints close to each other, I will certainly meet the requirement of staying withing one wavelength. >2; Horizontally polarized antennas should be oriented end-to-end >to each other to avoid significant parasitic interaction that washes >out the other differences in antenna performance My earlier comments about end-fed antennas focused on vertical wires since the thread originator had tall trees that suggest vertical orientation. My preferred 24? support poles used with 60+ ft wires lead me to the inverted vee configuration which will be horizontally polarized. I am surprised that you can avoid parasitic interaction if you place the wires end-to-end. I was under the impression that end-to-end vertical wires, as in an elevated vertical with a resonant length of vertical feedline under it, with a common mode choke preventing current going from the radiator to the coax shield, would still suffer from parasitic coupling unless an additional common mode choke is added somewhere along the feedline to break up the resonance. I am influenced here by a QST article about vhf/uhf verticals where it seemed that multiple common mode chokes were found necessary to prevent feedline radiation. Anyway, these situations should be easy to model, and I assume you have looked closely at it. I should have enough room to place my inverted vee?s end-to-end if you are sure that is the best way. >3, Do not attempt to compare horizontally polarized antennas to >vertically polarized antennas, independent selective fading >becomes a significant source of measurement error that takes >an extraordinary amount of data collection to overcome. Comparison between horizontal and vertical configuration is not part of my present plans, but I have to admit previously comparing my R5 vertical to my horizontal HF beam. I ran it several hours in several sessions at different times.There were times of day where sometimes the vertical seemed to work better than the beam, although overall the beam looked much better. Do I understand you to say that this comparison was flawed because of insufficient time spent? 73, Erik K7TV >Enjoy! >73 >Frank >W3LPL From hhoyt at mebtel.net Mon Nov 20 01:35:26 2017 From: hhoyt at mebtel.net (Howard Hoyt) Date: Mon, 20 Nov 2017 01:35:26 -0500 Subject: [Elecraft] (OT) - Unplanned Discovery Message-ID: Hi Stan, One thing we have learned in supplying thousands of Kx33s to hams is the importance of minimizing or eliminating common-mode currents in the antenna system.? The transverse mode RFI output of the Kx33 is extremely low and has never been the cause of noise to our customers, but if the antenna system has significant common-mode potential, it will always seek a current path through whatever is attached to the rig...through the power supply, your body, as well as grounds.? The outside of the coax shield, the rig, the power supply and AC mains are all in a series path for common-mode currents. The most direct cure is to place a high common-mode impedance in the antenna feedline.? The DC power lead on the Kx33 is smaller in diameter than most RF coax lines, so it may be easier to form a choke on that cable.? You mentioned "YES, I HAD CHOKES ON ALL SUPPLIES, CABLES, WIRE."? The exact core material used and number of turns is important in constructing common-mode chokes.? Jim Brown, K9YC has excellent tutorials on this subject: http://audiosystemsgroup.com/RFI-Ham.pdf Another measure which will shunt common mode currents away from other paths is a low impedance ground on the rig. Something else I want to mention, as it is an issue which has cropped up recently: There are several sellers on both eBay and Amazon stating "Pro Audio Engineering? Kx33 power supply" in their ads, but no supplies other than those sold directly from us are the actual Kx33.? We know this because we worked with one such customer to resolve noise issues and it turned out the unit he had was not a Kx33.? eBay and Amazon both state they can not do anything, since the other vendors are claiming they use our part number and name only to state an equivalency, which they most assuredly are not.? Our Kx33 has less than 70 pF of input to output coupling vs. 1000 pF or more for most other supplies, making it far easier to choke common-mode currents.? This was the most difficult spec of the supply to arrive at, but considering we knew it could be used with temporary antenna systems with common-mode potential it was important to achieve. As we unconditionally guarantee everything we sell, please contact us at info at proaudioeng.com and I am sure we can help you eliminate this noise or refund your purchase price.

I've noted how quiet my radio is when no one around us has power. Even running our 6500w Honda invertor-generator its very quiet (which also tells my noise is coming from neighbors and not my appliances). Also, I have found the IBM Think pad (laptop) is very quiet (even with charger). I think this largely because the case is metallic and not plastic. This story does remind us to periodically check our house for noise sources - might be pleasantly surprised. I have been plagued by S9 level interfering noise on 144-MHz for 3-4 years. Recently I checked coax loss on some lines when I had to roll up all for some house work. I found excessive loss in my two 130-foot LMR-400 Rx lines (runs from preamps on tower to transverter in house). Since replacing the lines I think I have lessened the interference, making suspect some may have been due to passive intermod in those lines. Loss was probably moisture caused corrosion which might interact with out of band signals. Passive IM is tested by the cellular industry at their tower sites. I still see occasional noise interference but its less often and less problem-some. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From kevin at ve3syb.ca Mon Nov 20 02:19:06 2017 From: kevin at ve3syb.ca (Kevin Cozens) Date: Mon, 20 Nov 2017 02:19:06 -0500 Subject: [Elecraft] O.T.

At light load the SMPS may enter a pulse skipping mode. Some keep pulse width constant and vary switching frequency with load to effectively change duty cycle. Most (all?) will continuously modulate the switching frequency over a small range to spread out the pulse energy. This makes it much easier to come in under required limits, but also by the time you're looking at harmonics up in our bands it's a big smudge of noise. 73, Josh W6XU Sent from my mobile device > On Nov 20, 2017, at 12:58 PM, Doug Smith wrote: > > I have often wondered if the noise from a switching power supply would vary in intensity or other characteristics as the load changes.

I was a USAF Morse Intercept Operator for almost 8 years. Started in Mar 1955. School was 7 months. Of that, CW training was 3+ hours a day, 5 days a week, for 7 months. Graduating speed requirement was 20 wpm. I started knowing zilch, ended up school at 23 wpm. Characters taught then were A thru Z, 1 thru 0, plus "special characters". Total character count was in excess of 45 characters. Some special characters were colon (:), semi-colon (;), ampersand (&), dollar ($), exclamation point (!), quotes ("), plus other normal punctuation marks. I worked as a MIO for 6 1/2 years in Europe. Germany, Turkey, and England. Consecutive tours. We copied CW as it was sent. If it ended up looking like Greek, or any other language, it was still CW, but transcribed onto paper, as whatever was sent. No computers back then, just a pair of Hammerlund SP-600's, R-390's or 51J's, and a Royal or Remington manual mil spec typewriter, and lots of 6 ply, fan fold paper with carbons. In Turkey, the building next to our ops area was Navy ops. Their CT's were reknown for being pretty excellent operators. Glad to see the Navy MIO's back. Just my $0.02 worth. 73, Rick, W7LKG -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Kevin Cozens Sent: Sunday, November 19, 2017 23:19 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] O.T.

I am not certain why you think the signal filtering would be an advantage. The filtering in the K3/K3S is mostly in the receive path (except for the TX EQ). The device you mention is transmit only, and you view the results of your transmitted signal on the internet. OTOH, if you are refering to the K3S Low Pass Filters (the bare wspr-lite has no low pass filters and they must be added externally), then again, there is no externally accessible path to run wspr-lite through those K3S filters without significant modification. 73, Don W3FPR On 11/20/2017 8:49 AM, David Windisch wrote: > Hi, all concerned: > Could this wsprlite-flexi device described here: > https://www.sotabeams.co.uk/wsprlite-flexi > be patched into the K3S to take advantage of its signal filtering and > (ahem!) amplification capabilities?

In my case, I use a W3YY optical encoder for FSK and PTT. FSK & PTT work fine with MMTTY, and PTT works with WSJT; however, when I setup FSK in 2 Tone, I get a brief (less than 1 second) RTTY tone, and that is all. I can see the entire message in the N1MM Digital interface, so I know the message has been generated. I am using serial RTS for PTT, and I can verify it is working by monitoring the voltage on serial Pin 7. When RTS is generated, I also see PTT activated (PTT is grounded, so voltage drops to zero). David, G3YYD, suggests NOT using FSK because the 2 Tone AFSK modes are superior (especially the differential mode, DOOK). These modes use VOX for PTT, and do work. I would like to get FSK working, too, so I can compare the RTTY transmit modes.

In other words, does it need bias or not? If it needs bias, then it is either the Proset-K2 or the Proset-iC. The K2 or iC designation is normally found at the base of the headset arm. If it is the K2 or iC version, then you should configure the K2 microphone configuration header for Elecraft including the bias resistor on the back of the microphone jack. If it is any other, it has a dynamic microphone and you should leave the bias resistor off. As for the Adapter, use the one for Kenwood (red band) and all will be well with either the electret mic Proset or the dynamic mic variety. It is the AD-1-K. Elecraft may have them available, but you can also buy one from Heil or any of their distributors. 73, Don W3FPR On 11/20/2017 11:47 AM, Dauer, Edward wrote: > I have a Heil Proset that I bought for use with my KX3.

The IF output of the K3 is 8.215 MHz so you would have to sample at twice this. On the other hand, the original questions was "Has anyone digitized the K3S IF and streamed it over an IP connection?" and the answer is yes, many people people have. However, there is always something sampling the IF at the K3 and then providing some sort of processing before hand. For example you could hook up an SDRPlay and sample at 2MHz and you will then have a maximum bandwidth of 2MHz. That will be perfectly fine. However, again, it is not that efficient. What do you want your panadapter to display? Your display has a finite number of pixels. Today, the highest resolution would be 4K where you have 3840 data points. Why send all 4 million data points when you need to display only 3840? Of course I'm simplifying this a lot but it's the general idea. There are lots of solutions out there. Just look up software defined radios and dongles and find some drivers that will stream the data. 73 Tom va2fsq.com -----Original Message----- From: Jim Miller Sent: Monday, November 20, 2017 2:32 PM To: Tom Subject: Re: [Elecraft] Digitized IF over IP?

One never knows. Almost 40 years ago I was an observer TDY at a major USN Communication Station when one of the periodical drills required suspension of satellite circuits and reversion to HF message transmissions for a day. It worked. I do know that the USCG had stopped Morse coverage many years ago, but until this year, their COMSPAC station (NMC) staffed by retired "Coasties" who were Morse operators "back then" would "go Morse" on several MF and HF channels for the "Night of Nights" event held by the Maritime Radio Historical Society. AFAIK this year would be the last one because the transmitter that was configured for that event was being replaced by one required other duties. ---- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From k6dgw at foothill.net Mon Nov 20 15:27:41 2017 From: k6dgw at foothill.net (Fred Jensen) Date: Mon, 20 Nov 2017 12:27:41 -0800 Subject: [Elecraft] JT modes RemoteRig?

Of course, that will not show you the P3 screen nor even the SVGA screen (unless it is done using a camera), but if the P3 IF OUT is connected to an LP-PAN box, the baseband I/Q outputs from LPpan run to a quality soundcard can produce a panadapter display on the computer monitor. NaP3 will also provide rig control, and Win4K3 will do that as well and also allow linking with several other logging applications, CW Skimmer, and many others. I am not certain about latency concerns, and that may be a problem on CW, but it may not be a problem on phone. Tom VA2FSQ (the author of Win4K3) has some other possibilities such as his support for video capture of the P3/SVGA screen, so that may give you some additional possibilities for solutions.

If you're smart enough to have saved them, there's a good chance you won't have buy anything. Simply select one with the matching voltage and rated for the needed current, cut the cables to both old and new warts, splice the old wart to the connector that mates with the unit you need to power. Older warts are often available at second hand stores and flea markets. $1 is the going rate. In general, linear warts are much heavier than SMPS units, so that's a good first check. A better one is to plug it into AC and hold a portable radio next to it tuned somewhere near 2 MHz (like the top of the AM BC band). If you hear hash, it's a switcher. If you don't., 99% chance that it's linear.

Message-ID: Relaying FFT spectrum data to another computer is certainly doable. For example, N1MM Logger+ can relay its spectrum display window to other instances of N1MM+ over a LAN or the Internet. If you have a copy of N1MM+ running at the radio site and equipped to display a spectrum window, that copy of N1MM+ can relay its spectrum window data to another copy of N1MM+ running somewhere else. Either copy of N1MM+ can be the one doing the actual logging. With a K3/K3S, at the radio site you would need an SDR such as the SDRPlay, or an LP-PAN plus a good sound card, plus software: Win4K3Suite, or N2IC's Waterfall Bandmap program, together with a copy of N1MM+. At the remote control site, all you need is N1MM+. See the online documentation for N1MM+ (the Spectrum Display Window web page) for details. 73, Rich VE3KI From wunder at wunderwood.org Mon Nov 20 19:58:12 2017 From: wunder at wunderwood.org (Walter Underwood) Date: Mon, 20 Nov 2017 16:58:12 -0800 Subject: [Elecraft] Digitized IF over IP?

First I need to ask what specifically are you having trouble with in the transmit alignment. If it is that you cannot adjust the pre-mixer and RF bandpass filters on the band board, all I can say is that you should re-do the receive alignment with a strong signal source of a known frequency within the tuning range of the K1. Although on-the-air signals may be sufficient, they may not tell the entire story. First make certain the BFO is adjusted properly to peak the FL3 passband at your preferred sidetone pitch. Then turn the switch on the bottom of the K1 board to the TEST position and adjust the TX Offset trimmer so the audio frequency is the same as your sidetone pitch (use SPOT to zero beat). Spectrogram is useful in setting te audio pitch properly. You can download Spectrogram from my website www.w3fpr.com. Scroll down on the opening page for the links. After doing that, re-do the Premixer and RF Bandpass adjustments in transmit mode with the OUT parameter set to 1.5 watts. Adjust for peak output power on each band. I can do the alignment/repair/calibration of your K1 if you do not want to pursue it on your own. You can send me a private email and I will send you my service form. 73, Don W3FPR On 11/20/2017 8:11 PM, Thom wrote: > I built my K1 and I was so careful to make sure I did everything right. > > I have the receiver aligned but for some reason I cannot get the > transmitter to align at all. > > I do not have the time,? with everything going on, to try and > troubleshoot this thing. > > I would like to find someone I can send this radio to and get it up and > running like it should. > From huntinhmb at coastside.net Mon Nov 20 20:50:49 2017 From: huntinhmb at coastside.net (Brian Hunt) Date: Mon, 20 Nov 2017 17:50:49 -0800 Subject: [Elecraft] Walwarts - linear supplies In-Reply-To: <002201d36259$3e7458a0$bb5d09e0$@biz> References: <011b01d3623f$57a88540$06f98fc0$@verizon.net> <3950aa7c-1263-5a11-22a5-3a35039981eb@subich.com> <002201d36259$3e7458a0$bb5d09e0$@biz> Message-ID: <741B2C11-CBCF-4DC9-884E-0DC7E992933A@coastside.net> Be careful using the non-regulated linear wall warts.

The max BW required at the 1st IF to just bring it down and feed my P3 is 200 KHz, and I never use more than 50 KHz spans, usually 20 KHz on CW. With RemoteRig, my K3 looks, feels, and sounds like it is actually making the RF. Would be nice to include the P3 in that.

Whatever settings I had simply worked for every condition during the weekend, and besides, I always seemed to be focused on signals and never on the rig itself, thanks to this ability of the K3 to vanish while you're using it. This year I operated with DUAL PB for the entire contest. With the context bandwidth set to 500 Hz it sounded tight and open at the same time... really interesting... and I found it to be free of ringing. The K3 is so highly configurable and DUAL PB is just one more way to make it sound consistently fresh. Tonight I started thinking about the next contest -- the best contest of the year, may I say-- which is the 160 meter contest in less than two weeks, and so I set up the N6RK receiving loop and diversity reception. In so doing, I reminded myself of the major reason why I got the K3 all those years ago. As I type this I'm listening to 80 in diversity and it's almost spooky hearing signals swim around in the soundstage of my headphones. What would have been a deep fade turns into the gentle movement of the signal from left (main receiver on the horizontal) to right (sub on the loop) and back again. Amazing. If you haven't tried diversity, it's worth the effort. There's KI6BZT in Oakland, slightly biased toward the left headphone, occasionally leaking right of center, talking to K6UIP in Encinitas slammed to the right. And sure enough, Neil says he's on a vertical antenna. And further down the band, at 3508, an HK0 calling CQ, who I don't think I could have had a chance of hearing without diversity. I'm sure I'll hear you on the 160, thanks to DUAL PB and diversity, but you probably won't hear me (but that's not the K3's fault; unfortunately, I'm on a very small city lot). I'll make my 50 contacts, and I hope you're one of them. Al?

The vast majority of linear wall warts are UN-regulated, but the current drawn by the equipment being powered significantly reduces the output voltage, usually to the rated value. That's how linear, unregulated power supplies work. That's why it's good to match both rated voltage and current. AND -- most equipment will tolerate moderate over-voltage. The K3, for example, is rated for 15VDC max. And, or course, not all gear runs on 12VDC -- lots of stuff runs on 5V, 7.5V, 9V, and 14V. > Best to measure OC first! Measuring OC is a good thing, and EXPECT to see 25-30% higher voltage than rated. But what matters is the voltage under load. And that's why my applications note recommends putting Power Poles on both the wart and the connector to the equipment, then sticking a voltage monitor in line with the equipment connected.

You do realize that its very wideband at that point. Roofing filters follow the 1st IF to feed the 2nd IF and DSP ckts. I run two LP-Pan from the IF of both my main and subRx on the K3. Input bw of the LP-Pan is 400-KHz and can provide 196-KHz IQ baseband output. I also have a SDR-IQ with max bw of 190-KHz. I only utilize that bw when measuring sun noise on 1296; normal bandpass for monitoring is 100-KHz which covers eme sub-bands. For MAP65 I only monitor 60-KHz (144.095-144.155 MHz); Map65 takes output of two LP-Pan into a Delta44 soundcard which has 96 KHz bw. My emu0202 can do 196 KHz but run from K3 audio out its limited to 4-KHz bw. I would guess the 1st IF would receive bw of a complete band (28-30 MHz on 10m). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From K8UT at charter.net Tue Nov 21 05:48:19 2017 From: K8UT at charter.net (Larry (K8UT)) Date: Tue, 21 Nov 2017 10:48:19 +0000 Subject: [Elecraft] Walwarts - linear supplies In-Reply-To: <3950aa7c-1263-5a11-22a5-3a35039981eb@subich.com> References: <011b01d3623f$57a88540$06f98fc0$@verizon.net> <3950aa7c-1263-5a11-22a5-3a35039981eb@subich.com> Message-ID: Two years ago, I embarked on a "wallwart-ectomy" in my shack, removing all wall warts and replacing them with DC power cords that connected to fused dc power strips, connected to a single shack linear supply.

For low counterpoise losses, small counterpoise current is desirable, which means a high antenna impedance. When a long counterpoise wire is needed, and when that wire is close to the ground, I would also expect ground losses from the counterpoise current interacting with the ground, in addition to the ground losses caused by the antenna wire interacting with the ground. When the feeder (outside or shield)-tuner-radio path carries all or part of the counterpoise current, I would not rule out the possibility that the possibiility that the resistance there is sufficient to cause losses significant enough to affect overall efficiency of the system. That is why I would like to compare like antennas with different feed systems. Of course antenna wire configuration is the most important thing to determine overall performance, but when putting up a long wire, I usually start with the support structure that already exists, or that I can put up most easily. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ignacy Sent: Tuesday, November 21, 2017 5:07 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KX3 Field Ant. for 80/40/30 Antenna performance does not depend on how it is fed (if feeder losses are low) but on height and ground type.

Frank, who is much more experienced with this comparison system, suggested that two horizontally polarized antennas should be oriented end-to end, due to parasitic interacton between the antennas. I questioned whether the end-to-end configuration would be free from interactions. Be that as it may, but while thinking about configuration choices, I came up with another reason why end-to-end would be the right thing to do. Suppose we are comparing two omnidirectional antennas such as verticals. Even if the receiving stations are unevenly distributed in different directions, the comparison based on received reports should be fair. If instead we are comparing two horizontal dipoles, that are not pointing in the same direction, and receiving stations are not distributed evenly in all directions, the antenna with fewer receivers in the main lobes would likely be at a disadvantage. If the feed system is the part that is different between the two ontennas, one could compensate, as I suggested, by swapping antennas for each feed system, but the time taken allows the conditions to change, so one would probably have to go back and forth a number of times to gain confidence in any observed difference in performance. Close to the coast receiving stations would be largely missing in roughtly half of possible compass directions, and unidirectional antennas would be affected more than a dipole with its bidirectional pattern. Much seems to depend on the proprietary algorithm used to composite a single performance number for from the WSPR received s/n rations at multiple receiving stations. What is the balance between the number of good reception reports vs. the distance for each one? When we talk about difficulty in comparing one vertical and one horizontal antenna, I suspect that similar considerations may account for result being inconsistent or difficult to interpret. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Erik Basilier Sent: Sunday, November 19, 2017 11:13 PM To: donovanf at starpower.net; elecraft at mailman.qth.net Subject: Re: [Elecraft] KX3 Field Ant. for 80/40/30 Hi Frank, Thanks for your very useful comments. Below my answers: >Radiation results from RF current flowing in an antenna. An RF >ammeter is a useful instrument for measuring the relative efficiency >different types of matching networks feeding similar antennas. Granted. I might want to add that to my plans. I know that the WSPRLite tolerates no more than 100 mW of reflected power, and to avoid accident risk I intend to set the transmit power to no more than 100 mW. I do not know how the units might fold back transmit power in a scenario where the SWR is good but less than perfect. For this reason I am planning to use a tuner whenever SWR is not very close to ideal. The location of the tuner would be wherever it would make sense to place it in field operation. If I add ammeters, they would be placed at the feedpoint, which should work well when I compare different impedance transformers using identical wires. If I compare to non-resonant wires or center feed, it would be hard to compare ammeter readings. > 1.

You are saying that this applies even if the comparison is done over several hours? In my limited back yard, and because I want the feedpoints close to each other, I will certainly meet the requirement of staying withing one wavelength. >2; Horizontally polarized antennas should be oriented end-to-end >to each other to avoid significant parasitic interaction that washes >out the other differences in antenna performance My earlier comments about end-fed antennas focused on vertical wires since the thread originator had tall trees that suggest vertical orientation. My preferred 24? support poles used with 60+ ft wires lead me to the inverted vee configuration which will be horizontally polarized. I am surprised that you can avoid parasitic interaction if you place the wires end-to-end. I was under the impression that end-to-end vertical wires, as in an elevated vertical with a resonant length of vertical feedline under it, with a common mode choke preventing current going from the radiator to the coax shield, would still suffer from parasitic coupling unless an additional common mode choke is added somewhere along the feedline to break up the resonance. I am influenced here by a QST article about vhf/uhf verticals where it seemed that multiple common mode chokes were found necessary to prevent feedline radiation. Anyway, these situations should be easy to model, and I assume you have looked closely at it. I should have enough room to place my inverted vee?s end-to-end if you are sure that is the best way. >3, Do not attempt to compare horizontally polarized antennas to >vertically polarized antennas, independent selective fading >becomes a significant source of measurement error that takes >an extraordinary amount of data collection to overcome. Comparison between horizontal and vertical configuration is not part of my present plans, but I have to admit previously comparing my R5 vertical to my horizontal HF beam. I ran it several hours in several sessions at different times.There were times of day where sometimes the vertical seemed to work better than the beam, although overall the beam looked much better. Do I understand you to say that this comparison was flawed because of insufficient time spent? 73, Erik K7TV >Enjoy! >73 >Frank >W3LPL ______________________________________________________________ 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 ebasilier at cox.net From donwilh at embarqmail.com Tue Nov 21 21:09:10 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Tue, 21 Nov 2017 21:09:10 -0500 Subject: [Elecraft] KX3 Field Ant. for 80/40/30 In-Reply-To: <02a701d36332$e269de60$a73d9b20$@cox.net> References: <01bc01d361a2$2052cd50$60f867f0$@cox.net> <02a701d36332$e269de60$a73d9b20$@cox.net> Message-ID: <4b03fa97-1db0-cc4e-f537-537b6462da9c@embarqmail.com> Erik, About all you can conclude from the WSPR readings is the relative difference between antennas. If you want to compare two horizontal antennas, place them end to end. The radiation at the end is at a minimum and the antenna will not interact. As for comparing a vertical with a horizontal antenna, or two verticals, the only thing one can say is at that particular time and distance for propagation, one antenna is better than the other. That may not be true for other propagation conditions, so be careful when generalizing. As far as two horizonal antennas oriented in different directions, you would expect greater signal strength in directions broadside to the antenna. That directivity may be useful in actual use, but is not a valid comparison between the two antennas. 73, Don W3FPR On 11/21/2017 8:40 PM, Erik Basilier wrote: > I hope my interest in WSPRLite antenna comparisons doesn't lead this thread too far off topic, but I have further thoughts on how to orient the two antennas being compared. > > Frank, who is much more experienced with this comparison system, suggested that two horizontally polarized antennas should be oriented end-to end, due to parasitic interacton between the antennas.

Even if the receiving stations are unevenly distributed in different directions, the comparison based on received reports should be fair. If instead we are comparing two horizontal dipoles, that are not pointing in the same direction, and receiving stations are not distributed evenly in all directions, the antenna with fewer receivers in the main lobes would likely be at a disadvantage. If the feed system is the part that is different between the two ontennas, one could compensate, as I suggested, by swapping antennas for each feed system, but the time taken allows the conditions to change, so one would probably have to go back and forth a number of times to gain confidence in any observed difference in performance. Close to the coast receiving stations would be largely missing in roughtly half of possible compass directions, and unidirectional antennas would be affected more than a dipole with its bidirectional pattern. Much seems to depend on the proprietary algorithm used to composite a single performance number for from the WSPR received s/n rations at multiple receiving stations. What is the balance between the number of good reception reports vs. the distance for each one? When we talk about difficulty in comparing one vertical and one horizontal antenna, I suspect that similar considerations may account for result being inconsistent or difficult to interpret. > From no9e at arrl.net Tue Nov 21 21:38:08 2017 From: no9e at arrl.net (Ignacy Misztal) Date: Tue, 21 Nov 2017 21:38:08 -0500 Subject: [Elecraft] KX3 Field Ant. for 80/40/30 In-Reply-To: <02a201d3632c$f6faaa90$e4efffb0$@cox.net> References: <018601d3610f$83259b80$8970d280$@cox.net> <0424ed8d-7b33-c1ef-f90a-d0adb2d4d3a6@blomand.net> <02a201d3632c$f6faaa90$e4efffb0$@cox.net> Message-ID: I tested the endfed from myantennas at 1 kw. The transformer was only warm so no significant losses there. The feeder was RF hot so a toroid choke was added. Cable no longer hot and toroid cold. SWR low on many bands. So the only significant losses could have been through the ground. This is obvious after a bit of thought. A vertical or inv L ( or low inv V) needs either good ground or lots of radials for small ground losses. With endfed, there is one radial, the feeder. So excellent performance by the beach, not bad in good ground, so so in poor ground.

For low counterpoise losses, small counterpoise current is desirable, which means a high antenna impedance. When a long counterpoise wire is needed, and when that wire is close to the ground, I would also expect ground losses from the counterpoise current interacting with the ground, in addition to the ground losses caused by the antenna wire interacting with the ground. When the feeder (outside or shield)-tuner-radio path carries all or part of the counterpoise current, I would not rule out the possibility that the possibiility that the resistance there is sufficient to cause losses significant enough to affect overall efficiency of the system. That is why I would like to compare like antennas with different feed systems. Of course antenna wire configuration is the most important thing to determine overall performance, but when putting up a long wire, I usually start with the support structure that already exists, or that I can put up most easily. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ignacy Sent: Tuesday, November 21, 2017 5:07 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] KX3 Field Ant. for 80/40/30 Antenna performance does not depend on how it is fed (if feeder losses are low) but on height and ground type.

Here's my response. ******************** Welcome on being a new ham.? As to the antenna design..........well there is no such thing in existence. We usually camp in National parks and State parks.? There's usually a few to a lot of trees around.? I carry a 100 ft spool of #22 insulated hookup wire wound on a plastic spool.? That was the way I purchased it.?? Once the travel trailer is in position, I will scout out a nice tree limb some 15 to 30 ft off of the ground.? I then unroll about 50 to 75 ft or so of the wire from the spool, drop a half hitch around the spool to prevent the remainder of the wire from rolling off of the spool.? Using a method similar to that of "David when he slew the Giant", I hurl the spool over a limb.? Of course sometimes my estimated distance or height is in error and I find it necessary to make another attempt or two.? The spool and wire simply keep the wire taught over the limb and to the trailer.? On the trailer, I have a feed through which was originally for a TV antenna, no longer used for that purpose.? To this I attach the end of the wire to the F connector.? Inside I have a length of RG 58 coax that runs to the F connector and terminates into a BNC connectro.? This attaches to my home made L network for the tuner.? The L network is comprised of a single variable C of about 500 pF and an air wound inductor which is? 1 1/2" in diameter and about 6" long.? I have a 20 position tap switch that is configured so I can use individual tap or select turns of the inductor.? This is mounted in a4" x 4" x 8" aluminum? box with a BNC on each end. ?? I recall having about every 2 turns tapped to the switch.? Using this L network I can find a point of C and L values which produce suitable SWR, less than 2:1 for my operation. ? After all my RG-58 is only 6 ft long so there is little loss on HF in the "feed line". ? If this doesn't find a match, I just reverse the IN and OUT to provide a different impedance range. ? ? Should I then have difficulty in obtaining a match, I will loosen the wire, allow more to spool off and then try again. ? Usually a length of some 50 to 75 feet will work about any band except 160 M. ? I need more wire for that. When we are finished camping, I turn the end of the wire loose at the trailer allowing the spool and wire to fall to the ground, wind it up and stow it for the next adventure.??? All of this is best described as an end fed long wire with a L matching network.??? There is nothing exotic about it, no baluns, no specific lengths, just use the wire length and space available. In reading the various posts and opinions on the topic, I'm amazed at the lengths, expense and trouble many hams go to in order to put up an antenna. Hope this helps *************************** 73 Bob, K4TAX On 11/21/2017 6:06 PM, Ignacy wrote: > Antenna performance does not depend on how it is fed (if feeder losses are > low) but on height and ground type.

I have an RPi 3 with FLDIGI and WSJT-X installed. After MUCH effort over the past 6 months I have WSJT-X working. My problem now is that the PTT on the FLDIGI does not work. The PTT on the WSJT-X does work. It's underlying rig control is Hamlib. I am using the Elecraft USB to serial adapter connected to the proprietary K2 serial cable. Note that I have successfully used the K2 with a Windows PC running FLDIGI and WSJT-X for some time. I have configured FLDIGI for RigCAT. It communicates with the K2 (frequency, mode, filter selection) but no PTT. I have also tried Hamlib but it will not initialize. During an extensive troubleshooting process over the past 3 weeks with a ham on the Yahoo FLDIGI RPi group I tried FLRIG. It is fully functional with the K2 but when I try using it with FLDIGI nothing works ? no frequency control, no PTT, nothing! By this I mean that I am trying to use FLDIGI for the control. I have verified that I have all the correct settings in both FLDIGI and FLRIG with the ham that has been helping me. As a sanity check I installed FLRIG on my Windows machine and successfully ran FLDIGI there. Has anyone had similar issues?

If you want to compare two horizontal antennas, place them end to end. >The radiation at the end is at a minimum and the antenna will not interact. Years ago I was under the na?ve impression that if you buy a perfectly symmetrical GP, put it in a vertical position high up in the air, with no nearby metal objects, and run the coax perfectly vertically to a transmitter where the feeder hits the ground, you will get a nice pattern that is well predicted by a model. After all, the antenna manufacturer probably showed us that pattern in their catalog, and we have seen that pattern before in our antenna book. Well, not too long ago QST published an article that said (paraphrasing): "Not so fast. Sometimes you will get a very different pattern, and it may be terrible at the low elevation angles that you want." The reason: the feedline has current on the outside. How much will depend on its length. Putting a common mode choke at the feedpoint won't save you if the feedline is long; you may have to break up the current by several chokes along the line." The author supported this by theory as well as measurement. And why not? The feedline is a nearby metallic object, so why should it not affect the performance of the antenna? With that in mind, I have been expecting interaction also between two horizontal dipoles installed in line. I just went to EZNEC to check it. For the GP with a vertical, non-connected halfwave wire hanging under it, the center current in that wire came to about 1/4 of the GP drive current. The pattern was changed but not too badly. Then I modelled a horizontal dipole with another one mounted close off the end, in line. The center current in the non-driven dipole came to about 38% of the drive current in the driven dipole. The azimuth pattern was now a 4-clover similar to that of a full-wave dipole. In comparison tests where patterns are important, that is a lot of interaction between the two dipoles arranged end-to-end. I also modelled two horizontal dipoles mounted at right angles (one driven dipole end close to one end of non-driven dipole). Now the current in the undriven dipole got as high as about 58%. The azimuth pattern was now bidirectional with no difference front to back, but with a wider lobe on one of the sides. It seems that interaction is very significant regardless of orientation as long as the wires are close. >As for comparing a vertical with a horizontal antenna, or two verticals, the only thing one can say is at that particular time and distance for propagation, one antenna is better >than the other. That may not be true for other propagation conditions, so be careful when generalizing. >As far as two horizonal antennas oriented in different directions, you would expect greater signal strength in directions broadside to the antenna. That directivity may be >useful in actual use, but is not a valid comparison between the two antennas. Granted, but since I drank the WSPRLite antenna comparison coolaid, I view the ralated capability through a certain mental filter, which says, on the one hand, that it is a significant advancement in the art to using WSPR for antenna testing (the two WSPR transmitters combined with some special software proprietary to SOTABeams is more than just a combination of the transmitters), and on the other hand that the technique is based on certain assumptions that need to be examined if one tries to determine the limits of what is doable and what is not. For those readers that have not looked closely at what this new approach involves, even if they are familiar with WSPR by iteslf, I will summarize my understanding here. If you run a WSPR transmitter (or two) you can go to the free website and get a list of stations that heard you and see the s/n ratio for each. You quickly get overwhelmed by all the data, The distance to the receiving stations that heard you is probably a positive to you, and so is the number of stations that heard you. Maybe you like a contest that gives you more points for greater distane, so you like to see dx stations in the list of stations that heard you. Maybe you do Field Day, and you get the same points regardless of distance. In either case, trying to evaluate the data presented to you as an antenna comparison is time-consuming and confusing. Enter SOTABeams. They set out to create software that takes data off the WSPR website, for each of the repeating WSPR transmissions, and combines it into one performance number for each transmission, for each of the two transmitters. The algorithm is proprietaty, so you don't know if a high number is high mostly because of good distances or because of many stations hearing you. I think we can assume that both distance and number of receiving stations play a role. The numbers we get from this software certainly doesn't correspond to something that we would really like to see, but it does reduce the confusing messes of data to single numbers that we can use to compare the two antennas. We log into a website (not the WSPR website that has all the s/n numbers) but one that shows two graphs overlaid, one for each transmitter/antenna. While we don't know what iach curve really represents, the people who created the algorithm seem to have struck on some reasonable choices. With only a few minutes between transmissions, we see the graphs suggest how one or the other antenna is doing better as a function of time, for a given day. We may see how one antenna does better than the other in late afternoon, consistent with the band "going long", and we may see the same thing repeat on multiple days. Of course we cannot translate the graphed numbers into anything like signal strength differences in db or relative gain. So, if we don't really know what the results represent, is this just a toy with no real usefulness? First of all, you could use two of your existing radios with digital mode setups, and just pay a modest amount for the software subscription (price and availability unknown), or you could buy the two WSPRLite transmitters at toy prices (about $75 each) and get a year of the software for free. To me the latter approach was a no-brainer. Once you program each transmitter (requires a computer) the WSPRLite transmitter (size is like a fat matchbox) doesn't need a separate computer to do its job (if you change call sign or grid square you do need to re-program.) So, in my view it doesn't cost a lot for an entry ticket to this capability to see how two antennas do better or worse relative to each other in some sense that is undefined, yet designed to be meaningful to the pursuits hams are typically involved in. While new data points appear on the two graphs every few minutes, selective fading means that we cannot even trust that Antenna 1 is doing better than Antenna 2 at this moment just because Graph 1 is on top of Graph 2 for the most recent transmission cycle. Over time we should get a clearer picture though. The WSPRLite transmitters have a start button that allows us to synchronize the transmission cycles; this helps make the results comparable, but other factors can hurt comparability: Distance between the two antennas, and difference in frequencies used (very very small). Frank suggested that antennas should be located no more than one wavelength from each other. I might want to model to see if interactions are necligible at that that distance. Obviously much depends on how long we are willing to test before we draw conclusions. Now that I have explained what the comparison system does, how can it exactly be useful to me to justify my investment ot $150? How "good" an antenna is cannot be stated without first defining what you want to use it for.I like to experiment with alternative antennas for Field Day. This means all contacts give me the same points, regardless of location. Located in AZ I expect to work the West Coast easily, while the East coast is more of a challenge. The first tool I use is EZNEC. I don't look for the highest maximum gain, but the gain at the elevation angle that is expected for the East Coast. I compare to a standard dipole, which has considerable gain over an isotropic, due to both its azimuth directivity and to ground reflection gain. The proposed new antenna may have a gain of, say 11dBi, but the dipole may be at say, 7dbi, which means the new antenna is expected to provide a 4 db improvement. I don't want too much gain/directivity anyway, since I still want to work the West Coast. But, does the actual antenna work as expected from the model? I haven't yet used the WSPRLite method for this actual comparison, but it seems to me that if I erect the new, horizontally polarized antenna close to, but not too close to, the standard dipole, both oriented toward the East Coast, and if I allow sufficient time for the comparison run, I have a good chance to see the new antenna dominate in the graphs. This isn't proof that the new antenna is better, but seeing it would give me increased confidence that the new antenna works as designed. My other use case is optimizing a long wire for quick setup portable operation using a single 24ft support, as previously mentioned on this thread. Here the two antennas would be very similar, which should improve the validity of comparison, but, I would again need to find a compromise distance between antennas that minimizes interaction while minimizes selective fading differences. With a horizontal wire mounted so low I expect that most qso's will be within the Southwest, and within that area the population of WSPR receiving stations may be homogeneous enough that antenna orientation doesn't matter much, but I don't see any reason not to to point both antennas in the same direction. It seems like I will need to use considerable feedline lengths in order to get the separation while keeping the transmitters close toghether so I can use both hands to start both at the same time. That probably means that I need more space than my back yard provides. I can't help thinking about how the comparison software might take into account the distance to receiving stations versus number of stations. I speculate that different formulas might be optimal for use cases involving differet types of contests. Maybe SOTABeams might be persuaded in the future to let users configuse the software for such different needs. Maybe the next step after that would be to let the formulas be tailored further to fit the beamwidth of a beam, and to compensate for different parts of the worlkd having different densities of WSPR receiving stations. 73, Erik K7TV >73, >Don W3FPR On 11/21/2017 8:40 PM, Erik Basilier wrote: > I hope my interest in WSPRLite antenna comparisons doesn't lead this thread too far off topic, but I have further thoughts on how to orient the two antennas being compared. > > Frank, who is much more experienced with this comparison system, suggested that two horizontally polarized antennas should be oriented end-to end, due to parasitic interacton between the antennas. I questioned whether the end-to-end configuration would be free from interactions. Be that as it may, but while thinking about configuration choices, I came up with another reason why end-to-end would be the right thing to do. > > Suppose we are comparing two omnidirectional antennas such as verticals. Even if the receiving stations are unevenly distributed in different directions, the comparison based on received reports should be fair. If instead we are comparing two horizontal dipoles, that are not pointing in the same direction, and receiving stations are not distributed evenly in all directions, the antenna with fewer receivers in the main lobes would likely be at a disadvantage. If the feed system is the part that is different between the two ontennas, one could compensate, as I suggested, by swapping antennas for each feed system, but the time taken allows the conditions to change, so one would probably have to go back and forth a number of times to gain confidence in any observed difference in performance. Close to the coast receiving stations would be largely missing in roughtly half of possible compass directions, and unidirectional antennas would be affected more than a dipole with its bidirectional pattern. Much seems to depend on the proprietary algorithm used to composite a single performance number for from the WSPR received s/n rations at multiple receiving stations. What is the balance between the number of good reception reports vs. the distance for each one? When we talk about difficulty in comparing one vertical and one horizontal antenna, I suspect that similar considerations may account for result being inconsistent or difficult to interpret. > From Gary at ka1j.com Wed Nov 22 07:40:11 2017 From: Gary at ka1j.com (Gary Smith) Date: Wed, 22 Nov 2017 07:40:11 -0500 Subject: [Elecraft] [K3] DUAL PB and Diversity In-Reply-To: <1676967852.116653.1511250904389@mail.yahoo.com> References: <1676967852.116653.1511250904389.ref@mail.yahoo.com>, <1676967852.116653.1511250904389@mail.yahoo.com> Message-ID: <5A15702B.19628.84ED617@Gary.ka1j.com> Al, Nice read. I agree wholeheartedly with you. I had never used the APF/DUAL PB until Wayne, I believe it was, mentioned it some time back. I'd tried it in the beginning but wasn't skilled using the radio then and it was left by the wayside. I had used Diversity often and with great success, it always was a plus for me and any insertion loss was certainly either made up for by adding the preamp or at the least by the increased quality of the signal received. In my case I have the 200Hz filters in the main & Sub Rx board and often run the width down as tightly as possible and if I must, adjust the RF gain to compensate for band conditions and I don't find any ringing. If the RF adjustment is causing a loss with band conditions, I open up the width a little and still use the RF, but not as aggressively. With that, I miss nothing in there and have as tight a width as possible with excellent tone from my received signals. Add to that the magnificence of the SubRx and It's genius. I would never be without the Sub Receiver, it's to me, absolutely essential for me to copy as best is possible.

The "simultaneous spots" comparison tool on DXplorer.net allows you to select the maximum distance for the WSPR reports being evaluated. It also computes the mean and standard deviations in dB between the two WSPRlite transmitters (and antennas) being compared. There's no magic here. Because the ionosphere and your antennas are the media connecting your WSPRlite transmitters to WSPR receivers all over the world, its very important that you take steps to reduce interaction among the antennas being compared and to reduce the ionospheric variability affecting usefulness the reported data. The important necessary steps are: 1. The antennas should transmit the same polarization. 2. The antennas should be as close as possible but not so close that they interact with each other (EZNEC helps you reduce interactions) This discussion needs to move off of the Elecraft reflector, it has little to do with the purpose of this reflector or Elecraft products The WSPRlite page on Facebook is a better choice. 73 Frank W3LPL ----- Original Message ----- From: "Erik Basilier" To: donwilh at embarqmail.com, donovanf at starpower.net, elecraft at mailman.qth.net Sent: Wednesday, November 22, 2017 8:43:57 AM Subject: RE: [Elecraft] KX3 Field Ant. for 80/40/30 Don, please see my comments below: >About all you can conclude from the WSPR readings is the relative difference between antennas.

Maybe you do Field Day, and you get the same points regardless of distance. In either case, trying to evaluate the data presented to you as an antenna comparison is time-consuming and confusing. Enter SOTABeams. They set out to create software that takes data off the WSPR website, for each of the repeating WSPR transmissions, and combines it into one performance number for each transmission, for each of the two transmitters. The algorithm is proprietaty, so you don't know if a high number is high mostly because of good distances or because of many stations hearing you. I think we can assume that both distance and number of receiving stations play a role. The numbers we get from this software certainly doesn't correspond to something that we would really like to see, but it does reduce the confusing messes of data to single numbers that we can use to compare the two antennas. We log into a website (not the WSPR website that has all the s/n numbers) but one that shows two graphs overlaid, one for each transmitter/antenna. While we don't know what iach curve really represents, the people who created the algorithm seem to have struck on some reasonable choices. With only a few minutes between transmissions, we see the graphs suggest how one or the other antenna is doing better as a function of time, for a given day. We may see how one antenna does better than the other in late afternoon, consistent with the band "going long", and we may see the same thing repeat on multiple days. Of course we cannot translate the graphed numbers into anything like signal strength differences in db or relative gain. So, if we don't really know what the results represent, is this just a toy with no real usefulness? First of all, you could use two of your existing radios with digital mode setups, and just pay a modest amount for the software subscription (price and availability unknown), or you could buy the two WSPRLite transmitters at toy prices (about $75 each) and get a year of the software for free. To me the latter approach was a no-brainer. Once you program each transmitter (requires a computer) the WSPRLite transmitter (size is like a fat matchbox) doesn't need a separate computer to do its job (if you change call sign or grid square you do need to re-program.) So, in my view it doesn't cost a lot for an entry ticket to this capability to see how two antennas do better or worse relative to each other in some sense that is undefined, yet designed to be meaningful to the pursuits hams are typically involved in. While new data points appear on the two graphs every few minutes, selective fading means that we cannot even trust that Antenna 1 is doing better than Antenna 2 at this moment just because Graph 1 is on top of Graph 2 for the most recent transmission cycle. Over time we should get a clearer picture though. The WSPRLite transmitters have a start button that allows us to synchronize the transmission cycles; this helps make the results comparable, but other factors can hurt comparability: Distance between the two antennas, and difference in frequencies used (very very small). Frank suggested that antennas should be located no more than one wavelength from each other. I might want to model to see if interactions are necligible at that that distance. Obviously much depends on how long we are willing to test before we draw conclusions. Now that I have explained what the comparison system does, how can it exactly be useful to me to justify my investment ot $150? How "good" an antenna is cannot be stated without first defining what you want to use it for.I like to experiment with alternative antennas for Field Day. This means all contacts give me the same points, regardless of location. Located in AZ I expect to work the West Coast easily, while the East coast is more of a challenge. The first tool I use is EZNEC. I don't look for the highest maximum gain, but the gain at the elevation angle that is expected for the East Coast. I compare to a standard dipole, which has considerable gain over an isotropic, due to both its azimuth directivity and to ground reflection gain. The proposed new antenna may have a gain of, say 11dBi, but the dipole may be at say, 7dbi, which means the new antenna is expected to provide a 4 db improvement. I don't want too much gain/directivity anyway, since I still want to work the West Coast. But, does the actual antenna work as expected from the model? I haven't yet used the WSPRLite method for this actual comparison, but it seems to me that if I erect the new, horizontally polarized antenna close to, but not too close to, the standard dipole, both oriented toward the East Coast, and if I allow sufficient time for the comparison run, I have a good chance to see the new antenna dominate in the graphs. This isn't proof that the new antenna is better, but seeing it would give me increased confidence that the new antenna works as designed. My other use case is optimizing a long wire for quick setup portable operation using a single 24ft support, as previously mentioned on this thread. Here the two antennas would be very similar, which should improve the validity of comparison, but, I would again need to find a compromise distance between antennas that minimizes interaction while minimizes selective fading differences. With a horizontal wire mounted so low I expect that most qso's will be within the Southwest, and within that area the population of WSPR receiving stations may be homogeneous enough that antenna orientation doesn't matter much, but I don't see any reason not to to point both antennas in the same direction. It seems like I will need to use considerable feedline lengths in order to get the separation while keeping the transmitters close toghether so I can use both hands to start both at the same time. That probably means that I need more space than my back yard provides. I can't help thinking about how the comparison software might take into account the distance to receiving stations versus number of stations. I speculate that different formulas might be optimal for use cases involving differet types of contests. Maybe SOTABeams might be persuaded in the future to let users configuse the software for such different needs. Maybe the next step after that would be to let the formulas be tailored further to fit the beamwidth of a beam, and to compensate for different parts of the worlkd having different densities of WSPR receiving stations. 73, Erik K7TV >73, >Don W3FPR On 11/21/2017 8:40 PM, Erik Basilier wrote: > I hope my interest in WSPRLite antenna comparisons doesn't lead this thread too far off topic, but I have further thoughts on how to orient the two antennas being compared. > > Frank, who is much more experienced with this comparison system, suggested that two horizontally polarized antennas should be oriented end-to end, due to parasitic interacton between the antennas.

Even if the receiving stations are unevenly distributed in different directions, the comparison based on received reports should be fair. If instead we are comparing two horizontal dipoles, that are not pointing in the same direction, and receiving stations are not distributed evenly in all directions, the antenna with fewer receivers in the main lobes would likely be at a disadvantage. If the feed system is the part that is different between the two ontennas, one could compensate, as I suggested, by swapping antennas for each feed system, but the time taken allows the conditions to change, so one would probably have to go back and forth a number of times to gain confidence in any observed difference in performance. Close to the coast receiving stations would be largely missing in roughtly half of possible compass directions, and unidirectional antennas would be affected more than a dipole with its bidirectional pattern. Much seems to depend on the proprietary algorithm used to composite a single performance number for from the WSPR received s/n rations at multiple receiving stations. What is the balance between the number of good reception reports vs. the distance for each one? When we talk about difficulty in comparing one vertical and one horizontal antenna, I suspect that similar considerations may account for result being inconsistent or difficult to interpret. > From w6jhb at me.com Wed Nov 22 12:45:24 2017 From: w6jhb at me.com (James Bennett) Date: Wed, 22 Nov 2017 09:45:24 -0800 Subject: [Elecraft] FLDIGI on Raspberry Pi PTT issue with the K2 In-Reply-To: References: Message-ID: Jim - For what it?s worth???

I agree that it would be nice to move discussion about WSPRLite to somewhere else. I do sometimes look at the WSPRLite Facebook group, but I don?t like it, partly because I dislike the whole concept of Facebook, and partly because I don?t like the cluttery interface that makes it slow to use. I like yahoo groups better, even though there is a lot to criticize about the interface for those. To those following this discussion in the Elecraft list, I want to apologize for the lack of formatting of my latest, very long post (and some earlier posts). I just haven?t learnt how to write a post in a proper editor and then transfer the content to a post while preserving the formatting. Any suggestions would be appreciated. Maybe there is some generic advice somewhere for all Nabble lists? In this short post I am separating paragraphs by return characters so that I see a single blank line between paragraphs. I am afraid that when you receive this, you will see too much space between paragraphs. Also for the Elecrafters that don?t already know the WSPRLite concepts, I want to explain that when Frank refers to DXPlorer, that is the actual trade name for the proprietary software that takes the free WSPR data and creates from it a single performance number for each transmission. (That is also the number graphed together with the number from the other transmitter/antenna used for comparison. In my previous posts I wanted to limit the post length by not mentioning the DXPlorer name. 73, Erik K7TV From: donovanf at starpower.net [mailto:donovanf at starpower.net] Sent: Wednesday, November 22, 2017 10:42 AM To: elecraft at mailman.qth.net Cc: donwilh at embarqmail.com; Erik Basilier Subject: Re: [Elecraft] KX3 Field Ant. for 80/40/30 Hi Eric, Don't give up on WSPRlite, with experience you'll learn that its an exceptionally powerful antenna evaluation tool. The "simultaneous spots" comparison tool on DXplorer.net allows you to select the maximum distance for the WSPR reports being evaluated. It also computes the mean and standard deviations in dB between the two WSPRlite transmitters (and antennas) being compared. There's no magic here. Because the ionosphere and your antennas are the media connecting your WSPRlite transmitters to WSPR receivers all over the world, its very important that you take steps to reduce interaction among the antennas being compared and to reduce the ionospheric variability affecting usefulness the reported data. The important necessary steps are: 1. The antennas should transmit the same polarization. 2. The antennas should be as close as possible but not so close that they interact with each other (EZNEC helps you reduce interactions) This discussion needs to move off of the Elecraft reflector, it has little to do with the purpose of this reflector or Elecraft products The WSPRlite page on Facebook is a better choice. 73 Frank W3LPL _____ From: "Erik Basilier" > To: donwilh at embarqmail.com , donovanf at starpower.net , elecraft at mailman.qth.net Sent: Wednesday, November 22, 2017 8:43:57 AM Subject: RE: [Elecraft] KX3 Field Ant. for 80/40/30 Don, please see my comments below: >About all you can conclude from the WSPR readings is the relative difference between antennas. If you want to compare two horizontal antennas, place them end to end. >The radiation at the end is at a minimum and the antenna will not interact. Years ago I was under the na?ve impression that if you buy a perfectly symmetrical GP, put it in a vertical position high up in the air, with no nearby metal objects, and run the coax perfectly vertically to a transmitter where the feeder hits the ground, you will get a nice pattern that is well predicted by a model. After all, the antenna manufacturer probably showed us that pattern in their catalog, and we have seen that pattern before in our antenna book. Well, not too long ago QST published an article that said (paraphrasing): "Not so fast. Sometimes you will get a very different pattern, and it may be terrible at the low elevation angles that you want." The reason: the feedline has current on the outside. How much will depend on its length. Putting a common mode choke at the feedpoint won't save you if the feedline is long; you may have to break up the current by several chokes along the line." The author supported this by theory as well as measurement. And why not? The feedline is a nearby metallic object, so why should it not affect the performance of the antenna? With that in mind, I have been expecting interaction also between two horizontal dipoles installed in line. I just went to EZNEC to check it. For the GP with a vertical, non-connected halfwave wire hanging under it, the center current in that wire came to about 1/4 of the GP drive current. The pattern was changed but not too badly. Then I modelled a horizontal dipole with another one mounted close off the end, in line. The center current in the non-driven dipole came to about 38% of the drive current in the driven dipole. The azimuth pattern was now a 4-clover similar to that of a full-wave dipole. In comparison tests where patterns are important, that is a lot of interaction between the two dipoles arranged end-to-end. I also modelled two horizontal dipoles mounted at right angles (one driven dipole end close to one end of non-driven dipole). Now the current in the undriven dipole got as high as about 58%. The azimuth pattern was now bidirectional with no difference front to back, but with a wider lobe on one of the sides. It seems that interaction is very significant regardless of orientation as long as the wires are close. >As for comparing a vertical with a horizontal antenna, or two verticals, the only thing one can say is at that particular time and distance for propagation, one antenna is better >than the other. That may not be true for other propagation conditions, so be careful when generalizing. >As far as two horizonal antennas oriented in different directions, you would expect greater signal strength in directions broadside to the antenna.

Granted, but since I drank the WSPRLite antenna comparison coolaid, I view the ralated capability through a certain mental filter, which says, on the one hand, that it is a significant advancement in the art to using WSPR for antenna testing (the two WSPR transmitters combined with some special software proprietary to SOTABeams is more than just a combination of the transmitters), and on the other hand that the technique is based on certain assumptions that need to be examined if one tries to determine the limits of what is doable and what is not. For those readers that have not looked closely at what this new approach involves, even if they are familiar with WSPR by iteslf, I will summarize my understanding here. If you run a WSPR transmitter (or two) you can go to the free website and get a list of stations that heard you and see the s/n ratio for each. You quickly get overwhelmed by all the data, The distance to the receiving stations that heard you is probably a positive to you, and so is the number of stations that heard you.

I agree wholeheartedly with you. I had never used the APF/DUAL PB until Wayne, I believe it was, mentioned it some time back. I'd tried it in the beginning but wasn't skilled using the radio then and it was left by the wayside. I had used Diversity often and with great success, it always was a plus for me and any insertion loss was certainly either made up for by adding the preamp or at the least by the increased quality of the signal received. In my case I have the 200Hz filters in the main & Sub Rx board and often run the width down as tightly as possible and if I must, adjust the RF gain to compensate for band conditions and I don't find any ringing. If the RF adjustment is causing a loss with band conditions, I open up the width a little and still use the RF, but not as aggressively. With that, I miss nothing in there and have as tight a width as possible with excellent tone from my received signals. Add to that the magnificence of the SubRx and It's genius. I would never be without the Sub Receiver, it's to me, absolutely essential for me to copy as best is possible.

I agree wholeheartedly with you. I had never used the APF/DUAL PB until Wayne, I believe it was, mentioned it some time back. I'd tried it in the beginning but wasn't skilled using the radio then and it was left by the wayside. I had used Diversity often and with great success, it always was a plus for me and any insertion loss was certainly either made up for by adding the preamp or at the least by the increased quality of the signal received. In my case I have the 200Hz filters in the main & Sub Rx board and often run the width down as tightly as possible and if I must, adjust the RF gain to compensate for band conditions and I don't find any ringing. If the RF adjustment is causing a loss with band conditions, I open up the width a little and still use the RF, but not as aggressively. With that, I miss nothing in there and have as tight a width as possible with excellent tone from my received signals. Add to that the magnificence of the SubRx and It's genius. I would never be without the Sub Receiver, it's to me, absolutely essential for me to copy as best is possible. Happy Thanksgiving to all who celebrate it. 73, Gary KA1J > As has been the case for the past several years the only K3 control I > touched during the CW SS was the tuning knob because there was never > any reason to futz with anything else.

Why do I think that? Because you said that fldigi does read the frequency, the mode, and the filter width. You also said that wsjtx, via hamlib, also controls the rig (ptt as well) via the same hardware setup. I assume you can change these values (freq, etc.) in fldigi and the k2 changes in a commensurate fashion. Ok, what's next? Hmmm... I assume you are using the K2.xml file from https://sourceforge.net/projects/fldigi/files/xmls/elecraft/. I wonder if the ptt cat command is not correct in that file. But you said fldigi on windows works and I assume you are using the same rigcat file (k2.xml)?? Is that correct, are you using the same rigcat file I reference? I had a quick look in that file (from fldigi rigs file download section on sourceforge) and noticed a small error. The following is incorrect from the file on the site: INIT *3* K22; The highlighted 3 should be a 4. The is supposed to include the semicolon in the tag. The effect of this error is that the K2 will likely not be placed in extended command mode. The TX; and RX; commands don't have extended modes. But, perhaps other commands that need extended mode might affect the TX and RX cat commands. Not sure. But, certainly worth changing the k2.xml file in ~/.fldigi/rigs to correct the error and then give it a try again. Also, I noticed in Elecraft's documentation that the K2 must be in either SSB or RTTY modes in order for TX; and RX; cat commands to function. The k2 won't respond when in CW to TX; and RX;. http://www.elecraft.com/manual/KIO2%20Pgmrs%20Ref%20rev%20E.pdf. I am not sure why Hamlib isn't working with Fldigi. I haven't had much luck with Hamlib and Fldigi and usually opted for rigcat. Mostly because it worked the first time (so I could start to operate and have fun) and I was able to tinker with the cat commands to add more customized filter widths and names than those provided in the kx3.xml rigcat file I use. regards, Brian VE3IBW On Tue, Nov 21, 2017 at 9:54 PM, Elmore's wrote: > Please carefully read everything that follows to avoid repetition of the > steps followed.

However, I have searched the archives and can?t find a satisfactory answer. I have a KX3, SN 70xx. I installed the internal battery option more than a year ago, however, I moved across country in July and haven?t connected the KX3 up to power until today. All NiMH internal batteries were removed in July and have not been reinstalled. I updated all of the firmware to the KX3 today. Went smashingly well. When I attempted to reset the internal clock on the KX3, I see 45.85.85 on the display with the last ?5? blinking slowly. Doesn?t matter whether UTC or Local time, same display. I?m assuming it is b/c that board has no battery backup, hence cannot be updated. I?m just asking to make sure that there isn?t another problem. I really don?t use the clock function that much when I operate. And, PS, Fred Cady?s encyclopedia on the KX3 doesn?t address this either.

I couldn?t agree more, Marvin. QRP works on multiple levels (challenging, amenable to home-brew, great for portable operation, etc.). My feelings on the subject are summarized in the poem below, written over 20 years ago. Under the circumstances, it?s not even OT. Happy Thanksgiving to all. Wayne N6KR * * * Q.R.Oscar and Q.R.Pete by Wayne A. Burdick, N6KR It happened in September, on a cold and stormy day; The mother of all contests was now nearly underway. Before the day was over, ears from Bonn to Surinam Would hear a battle rage between two different breeds of Ham. Oscar, a distinguished man of wisdom (and of wattage), Lit his pipe and surveyed his substantial shortwave cottage. "Let the games begin!" he cried, aglow with pride and power; And with a grin he swung his twenty-ton rotating tower. Not far away a man named Pete crouched low inside a tent, His sleeping bag was soggy and his penlight made him squint, Yet as he worked he smiled, twisting wires, tweaking pots, And soon his rig was bristling with two hundred milliwatts. Just after zero, zero, zero, zero (UTC), Both men tuned up on twenty and they listened carefully, But neither could believe his ears, and both began to pray: On 14020 they heard "DE Zed-A-1-A". Now Oscar moved up five Kc with dignity and class; He gripped his paddle deftly and prepared to pound some brass. The heterodynes were screeching, hungry birds caged in a zoo, But he could snag Albania in one call--maybe two. Pete took quite a different tack. He scanned for open space, Listening to the bedlam with a frown upon his face; He tugged his random wire to improve its ERP, And finally he found a place to sign "slash QRP." Well Oscar's monster, fire-breathing signal was the best, But Zed-A-1-A knew him, and felt sorry for the rest. With this in mind he listened for the meager and the brave, And ignored the QRO boys (who began to rant and rave). Soon the DX station heard a wimpy "QRP"; He fired off a "599" and waited patiently. But Pete was eating trailmix, now, and feeling quite dejected; Being called by rare DX was not what he expected. Oscar heard the call and moved in closer for the kill, Yet when he thought his turn had come the Q-so lingered still: "So how much are you running?" "A quarter watt or less." "A homebrew rig?" "My own design, or mostly, I confess." "Well I'm a QRP fan, too; good attitude to foster," Then ZA1A signed and said, "OK, it's your turn, Oscar." On Sunday Pete packed up his gear, his low-watt mission done. (Birds who'd perched upon HIS wire would live to tell their young.) Pete surveyed the hills and fields, a wondrous sight to feast on; Then he stuffed himself into his trusty, rusty Nissan. And Oscar? He had ruled the night with clear, demonic vision; Slicing QRM with his unleashed atomic fission. But near the stroke of twelve, he cut his drive by two dB, Then worked some rare DX and said, "Not bad for QRP!?

I vaguely recall a piece of a long poem published in QST many years ago that I read at my Elmer's house, noting everything he did, before going home to my trusty nth hand National NC-125 receiver and homebrew am/cw transmitter (how I envied his DX-100, the "Benton Harbor Kilowatt"). I know the attempted quote below is not accurate. Been trying to find it in my QST digital collection, but need to look harder. I do recall that the author had noted "...written in tribute to Edgar Allan Poe's 'The Raven'". "Once upon a midnight dreary, while I pondered weak and weary, lying on my shackroom floor, Came a burst of static from the attic, then a silence, nothing more..." I know that that second line does not flow properly, as in Poe's poem; needs another phrase. But, hey, I am old; and they do say the memory is the second thing to go. Not envying anyone's rig anymore (K1, K2, K3, KX3 in the shack); but I do wish I had one of them (any one!!) back then. Cheers, and Happy Thanksgiving to you folks in the US (hope you consulted with the turkey for his views on the whole business first). Alan VP1AS (then).

Date: Thu, 23 Nov 2017 10:03:12 -0800 I heard from one of our UK customers that 10 meter FM would be very useful on the KX2, at least in his area. If there???s enough demand for this, we could add it. The KX2 puts out 10 watts and has a built-in mic. Combined with a 10-meter whip it would work well as an HT on this band. 73, Wayne N6KR ______________________________________________________________ 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 w0pzd at juno.com ____________________________________________________________ We Say GoodBye To Sally Fields iflperfecttouch.com http://thirdpartyoffers.juno.com/TGL3141/5a17399bce46a399b067dst01vuc From n7xy at n7xy.net Thu Nov 23 16:34:02 2017 From: n7xy at n7xy.net (Bob Nielsen) Date: Thu, 23 Nov 2017 13:34:02 -0800 Subject: [Elecraft] CQ WW CW contest this weekend...pedestrian mobile In-Reply-To: References: Message-ID: <1d812e26-4894-21cf-e8d4-f6b369783085@n7xy.net> I was thinking of doing it running 5 watts to be in the QRP class, using my KX2 with the Elecraft version of the W6MMA screwdriver antenna (the Elecraft grey paint obviously contains some fine mojo).?

My use case is doing a SOTA activation in FT8 mode and having several callers waiting to work me so I could make 5 - 10 qso's in a row without gaps. That's when the KX2 seems to really heat up. It must be retaining heat through the 18 sec of down time before the next transmitting cycle, and this slowly raises the baseline temperature. This is evidently NOT a good use case for the KX2 at the 5 watt level, except perhaps if the ambient temperature is low. 73, Barry N1EU On Thu, Nov 23, 2017 at 9:46 PM, Tommy wrote: > Barry, > > I run 10w through my KX2 with the back leg down to allow for airflow > and don't find heat to be an issue.

In the Bay Area on 10GHz we have a linear translator (always on) that uses a -600KHz split. Most of us use FM through the translator (easier to set up the shift on FM than on SSB or CW).

I'm in similar situation when traveling by RV (no appreciable real estate for antennas). I am using a KX3 for my mobile/portable operation (HF probably more likely when parked at the end of the day's travel). The KX3 works very nicely with the KXPA100 if you decide you want more power (and its affordable for you). I made that decision two years ago. I install my KXPA100 under backseat of my crewcab pickup and have a coax line run for remote input of the KX3 from the 5th wheel. From an apartment or small home adding the KXPA100 is pretty easy (does not take up space and can be set on a closet shelf out of site with just coax and RJ45 control line going to the amp). I upgraded mine with the KXAT100 to make use of a vertical easier. But the KX3 with 15w and internal atu can do fine on its own. I plan to make a 76-day road trip this coming summer so will tell how that went. Still on the fence on antenna choice (simple/fast setup is a deciding factor so it may be a mobile screwdriver vertical). One thing I am puzzling on my setup is keeping the cable run to the RV simple (would like it to just be two coax lines: HF/6m and 2m). But keying the KXPA100 is an issue without either control line or PTT line. I'm thinking to make a RF sense ckt to key the PTT on the KXPA100. This more a question to Wayne. 73, KL7UW Date: Thu, 23 Nov 2017 10:13:29 -0800 From: To: Subject: [Elecraft] New to QRP Message-ID: <000001d36486$c43d18d0$4cb74a70$@nwlink.com> Content-Type: text/plain; charset="us-ascii" Since becoming licensed in 1967 I have always had better than average antennas with ample power. Since I have become older (now 80) my wife and I have downsized and I now longer have a location suitable for a large antenna system and have had to resort to a vertical. At first I thought that was a bad thing. Then I ran across a used KX3 and after having used it for a short while I have again discovered the anxiety and joy of making a contact with 12 watts. I have discovered a lot of being able to work the station is technique rather than brute power. Yes, high power will work but lacks the true joy is found when you can log the contact using a tin cup and a wet string. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From frantz at pwpconsult.com Fri Nov 24 01:10:19 2017 From: frantz at pwpconsult.com (Bill Frantz) Date: Thu, 23 Nov 2017 22:10:19 -0800 Subject: [Elecraft] MacOS High Sierra FTDI driver issue In-Reply-To: <0D8C8024-695B-465B-B35D-CFE400641976@mac.com> Message-ID: cocoaModem doesn't use the RS-232 connection to the K3.

"The Sub receiver's antenna can be connected to the ATU or to the auxiliary RF input. When you install your Sub receiver you must chose an antenna configuration and then physically connect a TMP cable inside the K3S from the Sub receiver's J92 antenna input to one of two places. First, you can connect the receiver to the K3S ATU, which allows the Sub receiver to share the same antenna the Main receiver is using (ANT 1, ANT 2, or RX ANT IN). You may also choose to have the Sub receiver use whichever antenna the Main receiver is NOT using (ANT 2 if Main is using ANT 1, or vice versa). You must set CONFIG:KRX3 Ant=Atu for this option. This may be your best choice for all around operating with a variety of antennas. The second choice is to connect the receiver to a separate auxiliary RF BNC antenna connector. In this case, the Sub receiver can share an antenna with the Main or it can use a different antenna connected to the AUX RF BNC. Set CONFIG:KRX3 Ant=bnc if you choose this option. This may be your best choice for diversity receiver operation with specialized receive antennas. A factory assembled K3S with KRX3 Sub receiver is delivered with its antenna connected to the AUX RF BNC (CONFIG:KRX3 Ant=bnc). Changing to KRX3 Ant=Atu will require you to open the K3S case and move a TMP cable from the BNC to the ATU. Refer to your KRX3 assembly manual for detailed instructions." With your antennas both being potential transmit antennas, I would recommend the first option.

You might be able to determine it without removing the top cover - just set the subRX to use the AUX input and plug the antenna into each jack one at a time. When you hear band noise or signals, that is the one connected. 73, Don W3FPR On 11/24/2017 12:37 PM, Tony G6GLP wrote: > Hi Guys, > > I built my K3 a couple of years ago complete with second RX.

Last Wednesday with the original keyboard connected, I was on 20 metres when the lights on the keyboard went off and there was no output to the PC. I found the cure was to use a large Type 31 ferrite ring and wind 4 turns of the keyboard USB cord onto it, right close to the USB connector at the PC end.

I have been reminded that one of the magnificent things about our hobby is that it has something to interest almost everyone. If you like digital, fine, if you like slow can tv, fine; if you like ssb, fine; if you don't have time for QRP, that is fine also. All of us can't have stacked monobander for 40 through 6 meters even though it might be nice to dream but during all of my 50 years as an amateur I always felt that if you need an antenna, put it up. I might not be conventional in the estimation of some one else but some wire is better than no wire. Don't be constrained by the "I don't have room" or "I can't". Where there is a will there is a way. That is my reason for a vertical and qrp. I have found I can have fun with that combination and that is what the hobby is all about. 73 and thanks for all the comments. KG7V cu in CQWW this weekend.

I put the core on the 25' RG174 feedline right at the 9:1 UNUN and was able to wind 10 turns.? Then I connected a 33' counterpoise wire to the output BNC using a hose clamp.? This was just a quickie "temporary" installation as it was getting dark here in NY. With no other changes made, I tried tuning up on 80, 40, 30 and 20 with my K2/10 and its internal KAT2 tuner. My 80 meter SWR which had been 1.1:1 was now an unusable 2.8:1.? This makes sense to me if the choke was now keeping the common mode currents from using "everything" connected to the K2!!? I would EXPECT 80 meters to have a high SWR for a 33' wire and it did!? My 40 meter SWR went from 1.2:1 to 1:1.? My 30 meter SWR went from 1.7:1 to 1:1 and my 20 meter SWR went from 1.1:1 to 1:1.? I was only able to make one quick contact but that was a pretty good one - Corsica - on 20M QRP. Then I put the new choke you sent me on the DC cable IN ADDITION to the cracked one that I already had on.? I detected NO NOISE at this point.? Switching back and forth from battery to Kx33 did NOT change the noise level. Of course, I'm going to keep experimenting through radial placement, elevation and number of radials but for now, it looks like you solved my "noise problem." That's a nifty sized little Kx33 power supply you sell and I'm glad I didn't give up on it.? I'm very pleased with the personal support you provided to me. Well, the CQWW starts in 15 minutes and I'm looking forward to a 'no noise' weekend! 73, Stan WB2LQF On Tue, Nov 21, 2017 at 03:07 PM, info at proaudioeng.com wrote: Hi Stan, That is great news regarding the antenna being outside, it is my experience and that of many customers that a common-mode (CM) choke at the feedpoint of an end-fed outside is highly effective at decoupling the feedline as part of the active antenna. In my opinion, and those of another expert in the field Jim Brown, it is money wasted purchasing a CM choke.? If you had not taken a look at his excellent paper on the subject here is the link: http://audiosystemsgroup.com/RFI-Ham.pdf Before I was able to measure the performance of chokes I had purchased both a W2DU and? DX Engineering choke myself, and thought they worked OK, but had no way to tell.? Once I started merely winding coax on mix 31 ferrites, I noticed they worked better than the ones I bought, and the cores are cheap.? I ended up selling the DX Engineering unit and in it's place I have two 2.4" mix 31 cores stacked (for higher power handling) with 8 turns of RG-8X, and it is superior.? Here is a chart showing how effective winding as many as 6-14 turns around that core can be, I suggest 8-10 turns depending on the size of coax you are using: I will send you a replacement for the small choke which broke in shipment, I am sorry for that.? I will also send you a 2.4" diameter mix 31 toroid core so you can make your own CM choke at the feedpoint.? The core is weatherproof, so don't worry about it getting wet.? I look forward to getting reports from you as to the progress taming this CM noise pickup, and thank you for your patience!? Ease of choking CM RFI is the real advantage to the Kx33 you purchased relative to other switchers, it is a characteristic we worked hard to engineer into the supply.

I have had to endure less-than-optimum antenna setups many times as well. One of the aspects of common-mode currents is they are reciprocal between transmit and receive.? In transmit they cause feedline radiation and a radiation pattern which is the combination of the desired antenna radiation and the feedline radiation.? In receive the feedline becomes part of the receiving antenna pattern, and since it leads right into your house, it is receiving any and all of the RF noise in your place.? The Kx33 has very low radiated noise, however if an antenna is placed close to it hooked to a sensitive receiver like that in the KX2/KX3, some noise may be heard. If you were to choke the feedline at the feedpoint/balun and add an additional counterpoise wire in the attic to help balance the antenna currents, you would achieve two goals: the antenna pattern would no longer be disturbed in receive or transmit by unwanted feedline currents, and your receive could potentially be much quieter than even now running from batteries.? I make this last point because even running from a battery I guarantee there are devices in your house which generate RFI like LEDs and fluorescent lights, not to mention the numerous little chargers we all seem to have scattered around for phones, toothbrushes, etc. and your counterpoise/antenna is close to them. As is obvious from its size, the ferrite included with the Kx33 is designed for 3-5 turns of the DC cable only.? I would be glad to send you at no charge a more substantial ferrite core which would allow multiple turns of coax, just let me know if you are interested.

I can only assume that the Kx33, while powered up, was sending RFI out via it's AC and/or DC cables which were lying on the floor about 5 feet away from the K2 even though unplugged from the K2? Please also note that in my post, when I reconnected my old Samlex 1235M, I also had noise.? And the darn computer supply added noise also. I will fall on my sword here and admit that I've had high noise for the last couple of years, ever since giving up my old fashioned analog supply but I never realized it.? I never made the connection.? ?I was a lousy problem solver and fell into the trap of ASSuming it was either my attic antenna picking up all kinds of stuff inside the house, or just the falling propagation conditions.? And I lived with it and still made contacts.? And that darn Laptop of mine was ALWAYS plugged in and turned on for QRZ.com, the reverse beacon network, or just so I could use Notepad with N1EA's "MILL" font to copy CW (I'm a former Navy Radioman and it's easier to type CW). But I have to say here that now that I'm totally on batteries, it's amazingly quiet.? I'm hearing QRP signals that were previously lost in the noise. After living with baseline S4 noise for so long, this is like heaven!!? I'm not going to return the Kx33.? It's the right size, puts out a full 14 volts and I'm confident I can ultimately solve the problem with the proper chokes, physical placement and perhaps even some shielding. I'm retired and we live in a townhouse.? Installing a proper ground is not possible for me.? It would be so far away that the connection would just be antenna.? For safety I disconnect my antenna when not operating.?? 73, Stan WB2LQF On Mon, Nov 20, 2017 at 01:35 AM, Howard Hoyt wrote: Hi Stan, One thing we have learned in supplying thousands of Kx33s to hams is the importance of minimizing or eliminating common-mode currents in the antenna system.? The transverse mode RFI output of the Kx33 is extremely low and has never been the cause of noise to our customers, but if the antenna system has significant common-mode potential, it will always seek a current path through whatever is attached to the rig...through the power supply, your body, as well as grounds.? The outside of the coax shield, the rig, the power supply and AC mains are all in a series path for common-mode currents. The most direct cure is to place a high common-mode impedance in the antenna feedline.? The DC power lead on the Kx33 is smaller in diameter than most RF coax lines, so it may be easier to form a choke on that cable.? You mentioned "YES, I HAD CHOKES ON ALL SUPPLIES, CABLES, WIRE."? The exact core material used and number of turns is important in constructing common-mode chokes.? Jim Brown, K9YC has excellent tutorials on this subject: http://audiosystemsgroup.com/RFI-Ham.pdf Another measure which will shunt common mode currents away from other paths is a low impedance ground on the rig. Something else I want to mention, as it is an issue which has cropped up recently: There are several sellers on both eBay and Amazon stating "Pro Audio Engineering? Kx33 power supply" in their ads, but no supplies other than those sold directly from us are the actual Kx33.? We know this because we worked with one such customer to resolve noise issues and it turned out the unit he had was not a Kx33.? eBay and Amazon both state they can not do anything, since the other vendors are claiming they use our part number and name only to state an equivalency, which they most assuredly are not.? Our Kx33 has less than 70 pF of input to output coupling vs. 1000 pF or more for most other supplies, making it far easier to choke common-mode currents.? This was the most difficult spec of the supply to arrive at, but considering we knew it could be used with temporary antenna systems with common-mode potential it was important to achieve. As we unconditionally guarantee everything we sell, please contact us at info at proaudioeng.com and I am sure we can help you eliminate this noise or refund your purchase price.

Fortunately, I keep various backups (K3EZ and Elecraft software) and VERY GOOD WRITTEN NOTES regarding all my settings. I was able to reset quickly and effectively. For rig control I sometimes use HRD (which does not change any settings and works well). However, my Genovation 48 key keypad is always on-line.

Operate into a dummy load - if you have the KAT2 installed, set the ATU menu to CALP and exit the menu. Then set the POWER knob to 5 watts and see whether the power output goes to something quite above 5 watts. If the power is significantly higher than that set by the POWER knob, then the K2 is not measuring the power output correctly. If you have the KAT2, there is a problem with the wattmeter on the KAT2. Most likely diodes D1 and D2 have been damaged by static coming from the antenna feedline. Those diodes are the first thing to check. If no KAT2, then D9 on the RF board is the most likely suspect. 73, Don W3FPR On 11/25/2017 9:09 PM, Oscar Castillo wrote: > hello all > > i have a problem whit my K2, on 40 meters band i have like 22 - 24 watts of power all the others bands are ok 13 - 15 watts on full power, and on SSB any band i hit the mike i get the CAL CURR sign, any clue what the problem are? > > thanks everyone for the advices > From nr4c at widomaker.com Sun Nov 26 10:37:53 2017 From: nr4c at widomaker.com (Nr4c) Date: Sun, 26 Nov 2017 10:37:53 -0500 Subject: [Elecraft] KX3 clock will not set from KX3 utility In-Reply-To: References: Message-ID: There is a timer in the KX3 that starts at zero when turned ON.

First of all, thank you all for your help and suggestions. I first, for both the Front Panel and the Control Board, verified that all the proper components were installed and in their proper orientation. No problems found here. I then went and reflowed all of the solder joints (well, all of those I could actually access). After reassembling the radio, I turned it on and got past the INFO 201. Good! Reflowing the solder must have fixed something somewhere. Now I have the INFO 080 message. Referring to Appendix E of the K2 manual, I quickly found the problem to be a bad solder connection on U1?s (RF board) 4 MHz resonator (RF-Z5).. Easily fixed that and checked all other solder connections of the RF board. Applied power. Ah, the wonderful sound of clicking relays! Looked at the display, and saw...gibberish. Decided to reset the radio again (4+5+6 then power-on). Got the INFO 201, followed quickly by ELECrAFt, followed then by 7100.00c. All tests and functions as outlined in Alignment and Test, Part 1, worked as expected. Happy to see that! Something still bugs me though. After reflowing the solder connections, I re-measured the resistance checks (per pg. 29 of the User Manual). I only list below the measurements in question: Test Point Signal Name Res. (to GND) Actual Measurement U1 pin 1 IDAT 25 - 35 k 8.84 k U1 pin 2 ICLK 25 - 35 k 8.93 k U1 pin 3 /SYNC 40 - 60 k 28 k U1 pin 5 5A 15 - 40 k 4.1 k U1 pin 12 2V 9 - 11 k 6 k J1 pin 15 VPOTS 10 - 60 k 4.3 k J1 pin 16 ICLK 25 - 35 k 8.9 k J1 pin 17 IDAT 25 - 35 k 8.7 k J1 pin 18 5A 15 - 40 k 4.1 k I realize that the primary purpose of the resistance measurements here are to check for opens and shorts, but given that the three boards appear to work as expected, I can't help but wonder if these measurements are OK as is, or is there something else amiss. I did check these with two different DMMs and the results were consistent. 73, Dan, K7DJK From: Don Wilhelm Sent: Thursday, November 16, 2017 5:07 AM To: dkredit10 at yahoo.com; elecraft at mailman.qth.net Subject: Re: [Elecraft] [K2] On initial Power-up, '"INFO 201" Remains Dan, The MCU is apparently not completing the initialization process. The INFO 201 should be shown only once (and not in normal operation). It will be shown once after a Master Reset. It should finish in about 30 to 40 seconds. The first thing to check is the soldering on the Control Board. Reflow the solder adding a bit more (to add a bit of flux). Use a hot iron (750 degF) and dwell on each connection until you see the solder flow out onto the solder pad and the component lead - that should take about 3 seconds, but if it takes up to 5, no problem. 73, Don W3FPR On 11/15/2017 8:55 PM, Dan, K7DJK via Elecraft wrote: > Need some help here. > > Been working on my K2 S/N 7770 and got to the point where power is first applied. > > Upon pressing the Power button, got the INFO 201 message, but it just remained on the display.

I can do 30 wpm without getting uncomfortable but I have experienced the "slowing down gets more contacts" phenomenon. Once in field day with a bunch of CW hands who can all copy and send above 40+ wpm. The one rule they had for field day was nobody sent faster that 22-25 wpm. They won their section and were a top 10 US 1A station almost every year. No problem holding a frequency. Same for Nov SS. Ripping along at 40wpm sure is neat and all but how long does the contact take when you add time for 3 or 4 repeats? Slow down to 22-25 wpm and get the contacts first time or spend time repeating parts of the exchange then ultimately having to slow down anyway.

I tried as I read on the forums with 5000, 10000, 15000 with regular and alt on CW. But I think I did something wrong. lol I went to put it back to factory and 1. Where I wrote it down got thrown away. 2. changed computer and did not have the recent back up config. I was wondering if you all kept files on the radio. I realize this is a long shot, but thought I would try. My K3 is Serial number 6294. I had it sent in for a K3syn board upgrade. I was able to find the very original config when the radio was brand new. Before the upgrades so I loaded it for right now. I had to go change the filter settings because I added the 6 since it was new. I had to turn on Tech mode, and I looked at the REF cal it is different from where I had set it. Okay just wondering what you would suggest?

It is also legal, but perhaps unwise, to use the spotting network to "read" the call signs. Wiser is to verify a spotted call sign, which is a lot easier than to copy it cold. In the unassisted categories, all these techniques are illegal. I think most stations were using a macro to send their report. Since the report in CQ WW DX is constant, setting up a macro is easy. Copying the report is a different matter, but I found the reports easier to copy than the calls, since the reports were all numbers (with some Ts, As, and Ns tossed in for brevity). 73 Bill AE6JV On 11/26/17 at 9:21 PM, marvwheeler at nwlink.com wrote: >I personally don't depend on the rig decoding but listening this weekend let >me know that either the big boys are using something to decode station >callsigns and are definite using an automated system to send their report. >Using the K3S cw speed option I saw several that read over 60 wpm.

It had worked fine for several years. I key the PTT and speak but no indication of audio input. The K3 receives normally on main and sub rcvrs. It can transmit SSB fine using the stored audio buttons. Tune control works. Auto tuner works. Everything else is normal. My K3 audio input is from a Plantronics mike to the Mic jack in the REAR panel. In the menu or config, rear panel Mic input is selected including the FET Bias. Front panel mike volume pot is set OK, usually at 12. The Plantronics Microphone tests fine on other equipment that has bias voltage, nice audio output at normal levels. Before this happened, I was adjusting some other menu settings. I don't currently have a mike for the front panel, so can't test that input yet. (Need to order a new MH2 from Elecraft, no other Kenwood mike available at the moment.). I cannot figure out what I did to make the rear Mic audio input stop working. Think its unlikely a transistor or op-amp just decided to die. Suspect I accidentally changed something in the menu or config system. Before I start taking things apart and hook up the o'scope and spend gobs of time with the schematics, does anyone have any suggestions for what menu disaster I may have caused? (I recall that Menu and Config has bitten me before) 73, Ron.

Am I right in recalling that the clock will run from External power, not pulling the battery down, if external power is available when the rig is turned off? If so, mine has an issue, as even with 24/7 external power (13.5V) when the rig is "Off", it will drain the internal batteries down to near zero! I have to periodically power the rig (if not regularly used) and recharge the batteries as a result. Is this "normal", or ??? 73. ??? Dave G0WBX.

It is also legal, but perhaps unwise, to use the spotting network to "read" the call signs. Wiser is to verify a spotted call sign, which is a lot easier than to copy it cold. In the unassisted categories, all these techniques are illegal. I think most stations were using a macro to send their report. Since the report in CQ WW DX is constant, setting up a macro is easy. Copying the report is a different matter, but I found the reports easier to copy than the calls, since the reports were all numbers (with some Ts, As, and Ns tossed in for brevity). 73 Bill AE6JV On 11/26/17 at 9:21 PM, marvwheeler at nwlink.com wrote: >I personally don't depend on the rig decoding but listening this >weekend let me know that either the big boys are using something to >decode station callsigns and are definite using an automated system to send their report. >Using the K3S cw speed option I saw several that read over 60 wpm.

Here you want to see that only CW elements flash the bar on the CWT indicator.? Most hams seem to believe more gain makes for hearing weaker signals.

I find it does required different values for different band conditions, usually impacted by noise. ?? I usually have mine at 3 or 4, never at AUTO.? Finally,? poorly timed CW elements will not decode correctly.?? I do find that near keyboard quality or keyboard sent CW decodes quite nicely.??? Of course a static burst, thus triggering the decoder will produce *** or random characters.??? Here AGC PLS value and the value of AGC SLP setting? has a marked effect on results.?

Rich, A very simple but effective anti-rotation device for right-angle-mounted whips can be made from a piece of rubber tubing or cylindrical extrusion. A short length can be wedged in between the whip?s loading coil and the right side of the radio for a compression fit. For MFJ18xxT series whips, I use a 3/4? length of 1/2" diameter tubing.

That was based on long studies that showed traffic moved faster at slower speeds because slower speeds avoided mistakes, requests for "fills", etc. In the Army we stuck with 13 wpm on the CW nets for the same reason (ca. 1960). That's the speed the radio schools trained operators to use. Note that these messages were commonly 5-letter code groups that were meaningless until decoded, so accuracy was critical. It wasn't possible to spot a mistake like one can in plain language text. It sounds like today's Ham contesters are rediscovering the same thing. 73, Ron AC7AC -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bob McGraw K4TAX Sent: Sunday, November 26, 2017 6:50 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] CW Contest and Elecraft K3s decoder Kevin et al; I agree, in fact I'd suppose as the CW speed the number of competent operators decreases proportionally.

A few speed merchants bang away at 35 WPM or above. I worked most of CQWW CW this weekend QRP with good antennas. I was able to get through pileups by sending my call at 30-32 WPM often fitting it in between others sending theirs. A station calling at 15 WPM takes twice as long to send his call (and stations with long calls take even longer), filling up much of the available space. I found this very frustrating when the QRS station was in W0 or the east coast and I'm in W6 trying to work EU stations with 5W. The CQWW exchange is stupid simple. 599xy, where xy is the station's zone. The US, Canada, Russia, and Australia are the only countries having more than one zone, and most contest logging software fills that in automatically when you enter a call. So if you're in the US or Canada, for 99% of contacts, all you need to copy is the call. Our group, W6GJB, W6JTI, and me, has won Field Day 1A Battery several times. When calling CQ, we usually work around 25 wpm, and toward the end will slow down a bit. I dropped in on N6TV working SS on Sunday afternoon at W7RN a year ago. He was working at about 25 wpm.? He's won SS from that QTH, and often works DX contests from K3LR. The guys at W3LPL were working at about 25 WPM this weekend. All three are super stations with spectacular antenna farms. FWIW, many serious contesters, including me, have found that even when a station calls at a speed much lower than we're working, they still copy our exchange when we slow down only a bit, which suggests that either they've listened to us for a while to copy our exchange before calling or that they're using a CW reader. And another FWIW -- putting a lot of hours into a CW contest will improve your code speed significantly! 73, Jim K9YC On 11/26/2017 6:49 PM, Bob McGraw K4TAX wrote: > I agree, in fact I'd suppose as the CW speed the number of competent > operators decreases proportionally.???

However some loud stations, I believe from Finland and Arctic Russia, sounded like a nearly solid tone if they sent much above approximately 18 WPM. I have noticed this on other occasions when signals passed nearly over the north pole. I have also noticed this when I have operated from north of the arctic circle in Europe. Repeatedly calling CQ at > 35 WPM is fine when they get answers nearly every time, but often they did not get any answers for long periods of time. If the DX would have slowed down (say to 16 or 18 WPM) for a CQ occasionally they would have probably picked up some of us who are propagationally and/or speed challenged and got a valuable multiplier like my Alaska section. I have operated as a maritime shipboard and also as a shore station CW op many decades ago. If we had long or complicated traffic to pass we would often slow down to <20 WPM even if both of us could copy faster. I did not have my K3S during that WPX contest, but doubt that even its good decoder could have done much with some of these 35+ WPM polar signals.

My logging program gives me 6.6 hours of operation with 119 QSOs, so that's about 18 QSOs/hour. I had plenty of time to copy the exchange given the number of times I needed to hear the call to be sure I had copied it correctly. This was particularly true for those stations that did not send their call at the end of every QSO. I would guess that this scenerio is why Jim observes the easy with which contest exchanges are read by slow operators. Remember, my goals were to improve my CW and have fun, not to rack up the bigest score. BTW, with 2 QSOs on 160M and 2 on 10M, I did manage QSOs on all contest bands. 37 Bill AE6JV On 11/27/17 at 10:44 AM, jim at audiosystemsgroup.com (Jim Brown) wrote: >FWIW, many serious contesters, including me, have found that >even when a station calls at a speed much lower than we're >working, they still copy our exchange when we slow down only a >bit, which suggests that either they've listened to us for a >while to copy our exchange before calling or that they're using >a CW reader. ----------------------------------------------------------------------- Bill Frantz | gets() remains as a monument | Periwinkle (408)356-8506 | to C's continuing support of | 16345 Englewood Ave www.pwpconsult.com | buffer overruns. | Los Gatos, CA 95032 From n9tf at comcast.net Mon Nov 27 17:53:49 2017 From: n9tf at comcast.net (EUGENE GABRY) Date: Mon, 27 Nov 2017 16:53:49 -0600 (CST) Subject: [Elecraft] CW Contest and Elecraft K3s decoder In-Reply-To: References: <000001d3673f$901e1ed0$b05a5c70$@nwlink.com> <004501d36787$3c60d060$b5227120$@elecraft.com> Message-ID: <279215119.111044.1511823229550@connect.xfinity.com> > On November 27, 2017 at 2:39 PM Fred Moore wrote: > > CW contests have > become a machine contest not a Ham contest... > This is something I fight personally when I decide to enter a CW contest. Technology is great, it has allowed those who are either not proficient at CW or can't even copy CW, to be able to communicate. I've always thought the focus of a "conTEST", whether CW or SSB was to test the capabilities of the "operator" to accurately receive the information sent, making as many contacts in the time period of the contest as possible. Scores determined in part, by busted calls or other information copied incorrectly, and then scoring against their peers. Today there are a lot of (Robots) that can decode CW. It is true that all robots are not the same, and errors could occur. Just wonder when we draw the line as to who/what is being judged for accuracy. I love the technology. It's great for communications. (I think you know where I stand on robotic modes like FT8 :) ) But in a contest, "these days" it seems to come down to who has the best robotics (machines) to eliminate the human element for the sake of driving up the score to new levels. 73 Gene N9TF From w0eb at cox.net Mon Nov 27 18:04:34 2017 From: w0eb at cox.net (Jim Sheldon) Date: Mon, 27 Nov 2017 17:04:34 -0600 Subject: [Elecraft] CW Contest and Elecraft K3s decoder In-Reply-To: References: <1333676e-2873-fc74-7533-b875ea1de3b8@blomand.net> Message-ID: In order to keep the robots from getting perfect copy on me either rag chewing or the very few contests I enter, I've stopped using a keyer and have reverted to sending with a bug.

NO truth to that at all You're absolutely right, Jim. It's those beginning CW ops who don't know CW, or haven't developed their copying ability to contesting speeds, or who don't feel confident about their copying ability, who are using code readers. Most serious contesters, including me, let their logging program SEND repetitive things. Some great contest operators still send a lot with a paddle, but let the computer call CQ. And some ops send a lot more with the paddle than they should. :) I used to have a pretty good fist, but it's declined with age.

I just saw another post about not sending over 30 wpm to have better rate, TI7W was sending much faster had a rate of about 210 per hour for the entire 48 hour contest.

However, many years ago when I got interested in QRQ, I had to use a code reader to get myself over the 55 wpm 'hump'. The 'hump' is where you have to re-learn how to copy code; and as I call it, you have to get into the 'flow' of the conversation. About 20 years ago, there were maybe 15 to 20 hams, nationwide, who were doing QRQ QSO's and they were pretty active, but they all could copy around 100 wpm. And with their really great sense of humor, made QRQ seriously fun part of the hobby. But NO, none of those folks ever did QRQ to 'impress anyone'; they only did it for the pure fun of it! CW and QRQ is just another FUN part of our hobby and it is not done to impress anyone! 73 and Merry Christmas, Tom - W4BQF - #149 -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of F5vjc Sent: Tuesday, November 28, 2017 1:26 AM To: Dauer, Edward Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] CW Contest and Elecraft K3 Decoder Very well stated Ted.

For me, the competition is me ? can I do a one weekend WAS, or closer to a clean sweep than I did last year? (Did that a couple of times, but not lately.) Can I do a one weekend DXCC?

Can I get my code proficiency up to the point that I can QSO faster than I can type? (Yup, done that.) Can I integrate new equipment and gadgets just to see if they help? Can I get Nebraska on ten meter CW which I have been chasing unsuccessfully for a 5BWAS for almost ten years? (If I had ever done that I wouldn?t have mentioned it.) Using a decoder would be contrary to what I am trying to do.

I mean only to say that contesting can be great fun despite what others are doing for their fun. With one exception. I would like to personally pour a beer on the head of operators (many of them DX) who program their memory keyers to send just their call at utterly incomprehensible speeds although every other part of the exchange is at 30 ? 35 or so.

I am a CW rag chewer but like the F1 button to send CQ in a contest and F2 to send the report. It saves my wrist. Copy is by my ears though the K3 decoder is there it will not cope with pileups so you use your ears. My new car has adaptive cruise control, lane assist and blind spot monitoring - great the car is a bit safer! Technology is what our hobby is about; FT8 and all. There are many rooms in the masters house. Enjoy and keep pounding the brass. 73 Doug EI2CN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of EUGENE GABRY Sent: 27 November 2017 22:54 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] CW Contest and Elecraft K3s decoder > On November 27, 2017 at 2:39 PM Fred Moore wrote: > > CW contests have > become a machine contest not a Ham contest... > This is something I fight personally when I decide to enter a CW contest. Technology is great, it has allowed those who are either not proficient at CW or can't even copy CW, to be able to communicate. I've always thought the focus of a "conTEST", whether CW or SSB was to test the capabilities of the "operator" to accurately receive the information sent, making as many contacts in the time period of the contest as possible. Scores determined in part, by busted calls or other information copied incorrectly, and then scoring against their peers. Today there are a lot of (Robots) that can decode CW. It is true that all robots are not the same, and errors could occur. Just wonder when we draw the line as to who/what is being judged for accuracy. I love the technology. It's great for communications. (I think you know where I stand on robotic modes like FT8 :) ) But in a contest, "these days" it seems to come down to who has the best robotics (machines) to eliminate the human element for the sake of driving up the score to new levels. 73 Gene N9TF ______________________________________________________________ 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 turnbull at net1.ie From pincon at erols.com Tue Nov 28 07:51:18 2017 From: pincon at erols.com (Charlie T) Date: Tue, 28 Nov 2017 07:51:18 -0500 Subject: [Elecraft] CW Contest and Elecraft K3s decoder In-Reply-To: References: <1333676e-2873-fc74-7533-b875ea1de3b8@blomand.net> Message-ID: <002801d36847$9901b8f0$cb052ad0$@erols.com> "In order to keep the robots from getting perfect copy on me either rag chewing or the very few contests I enter, I've stopped using a keyer and have reverted to sending with a bug.

It?s a bit like tennis, with the point being to keep a rally going, not to demolish the other guy. The other guy hits me a hard one, it?s a lot more satisfying to hit a hard one back. A less skilled player hits me a soft one, I?m not going to try to prove to him how hard I can hit it back. Rather I?ll hit it back at a pace appropriate for his skill level. If I?m tuning and hear a high speed guy (I?m one myself) I?ll make a point to work him. For if I don?t get through immediately, I won?t have to wait long for a second chance. TI7W and ZF2MJ weren?t running those awesome rates just because they were sending faster than the others. They were using (effectively) two radios at a time, interleaving QSOs on two different bands. That?s a skill beyond my pay grade. 73 - Jim K8MR > On Nov 28, 2017, at 2:38 AM, Jim Cassidy wrote: > > Absolutely correct.

And BTW, 140/hr on Field Day CW ain?t going to happen even running a great pileup. FD ops just aren?t as fast as European QRQ ops in CQWW or the like, and tuning around (however it is done) is never going to be as fast as having guys lined up to work you. When I describe contesting to non-ham friends I invoke a relatively recent ad campaign: It?s like finding a guy to say ?Do you hear me now?? to which he responds ?Yes, I hear you, do you hear me?? to which I respond ?Yes, now is there anybody else out there who hears me?? No, it?s not exchanging non-trivial information, and it?s not person to person chatting. It may not be one?s preferred cup of tea.

There should also be people who only call CQTEST and never answer a call, if there call shows that log is also tossed. >> >> I have not use for CW decoded qso's as a learning tool or otherwise.. off my soapbox >> >> Fred Moore >> email: fred at fmeco.com >> wd8kni at gmail.com >> phone: 321-217-8699 >> > > > ______________________________________________________________ > 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 jimk8mr at aol.com From radiok4ia at gmail.com Tue Nov 28 12:58:34 2017 From: radiok4ia at gmail.com (Buck) Date: Tue, 28 Nov 2017 12:58:34 -0500 Subject: [Elecraft] Lulu 40% off Message-ID: Lulu is running 40% off until Nov 30.

I usually don't go "assisted" but did this contest because I wasn't in it to compete but to give Q's to those in competition and I was on a time constraint. One call, I don't remember which it was was spotted in N1MM with a final suffix as "T" but whoever posted it was incorrect, it was a "N". The guy was sending pretty quickly, about 40 WPM and it was easy to miss but if I hadn't been listening to every letter and relied on the spot or the K3s reader, I wouldn't have gotten it & they were too faint (I think) for the CW reader to pick up well. Don't know, wasn't using it. That said, I'd rather have someone wanting to know CW use the reader than not participate in the contest because they still haven't become truly skilled at copying overly fast CW in a contest. As long as they're stressed enough to be in it, they will get better to where they don't need it. It's a crutch but sometimes we need to use crutches in life.

(Was KX3 clock will not set from KX3 utility) Message-ID: Re:? "...even with 24/7 external power (13.5V) when the rig is "Off", it will drain the internal batteries down to near zero!" One problem is that you now have damaged cells since they have been discharged to below 1 volt per cell.? I suggest you stop trying to troubleshoot your radio with damaged cells.?? Install a fresh set of low self discharge (LSD) cells and watch voltage daily until you have confidence that the voltage is staying constant.? I recommend Eneloops since mine have worked so well since I installed them in early 2013.? The voltage should remain constant for months once it has dropped to 1.2v per cell (1.2 x 8 = 9.6v). Sometimes my KX3 sits in my go pack with no external power for months.? Other times it sits on the desk connected to a 13.8v supply.? With Eneloops installed, I have not seen the discharge rates you have. I did experience similar discharge rates once when I tried a set of Energizer cells.? They were not LSD, however.? I quickly took them out and reinstalled the Eneloops. In response to your original question concerning clock (KXBC3) power source: I haven't looked at the schematic for a long time, but as I recall, the radio, including the KXBC3, are powered by the higher of the internal battery or external power voltages.? The radio portion is turned on and off by a MOSFET, but the KXBC3 is tapped off upstream (closer to the battery/power plug), so it can continue operation after radio shutdown.? This suggests that if your KX3 has external power applied and the battery is discharging, it is MOST LIKELY due to cell self discharge and NOT the radio or charger.? So do yourself a favor and install a new set of LSD cells.

Operated over 30 hours, made over 2500 QSOs and didn't find one rude op. What some of you guys consider rude operating is just "trading paint" in racing circles. If you think "just getting an automatic 599" is the only challenging thing about contesting, you don't contest. I can think of at least a half dozen things that are necessary: 1. Try keeping your butt in the chair for hours on end. 2. Know the propagation well enough to know when to point the beam for that zone 23 opening. 3. Able to copy a weak one through heavy QRM. 4. Know when to run and when to S/P 5. Have the skill to set up an ergonomic station 6. Know where and when to be on certain band depending on prop and band conditions. 7. Being able to do SO2R Try knocking off 10,000 CW QSOs in 48 hours. Better yet, try 5000 CW QSOs and then tell me how easy it is. I've been contesting for years and haven't done it.

The top ops are not using code readers or skimmers have suggested. Sure the exchange is easy, I am not sure if anyone is using 2BSIQ in Sweepstakes. But just pulling out callsigns in pileups where everyone picks on a spot and lands on the same frequency is no easy task with even one radio.

Fun to watch... this thread just keeps going but I'm glad to see some more rounded responses regarding contesting. I made a couple of videos running stations in the ARRL SS if you would like to see the perspective of a more involved exchange. I'm only running one radio, but you get some commentary along with me running the stations. You can't do any of this with a CW reader... it's just not possible or practical for that matter. I certainly don't have a huge pile up calling me, but it would just never work trying to use something that is decoding the CW. The only thing you use is the grey matter between your ears. I also make several fills using the paddle as you can see in the videos. *Here are the videos:* 20 Meters : https://www.youtube.com/watch?v=bTX255sEVpQ 15 Meters : https://www.youtube.com/watch?v=_GPhl8hiGgs Most would never put themselves out there for commentary... so here I go anyway. I hope someone finds the video interesting. The setup is a 4K desktop showing the new N1MM+ spectrum scope as fed by Win4K3Suite. I'm running along at a pretty good clip, but if you watch the videos, you will see that I QRS several times based on the speed and or copy of the calling station.

I operate very little SSB so can?t say if it happens on SSB. It seems that the transmit power as seen on the meter display drops to 0 on a character and then goes up to 100, even when running at 40 watts driving my amplifier, an ALS-600, modified with QSK. At first I blamed the amp and did check it out thoroughly, but see the problem even without it. I have checked all my coax connections, the amp keying keying connection, re-seated the power cable, tried both full and semi-qsk and both internal and external Winkeyer keying. I?ve seen this both with my antenna and with a dummy load. It doesn?t seem to matter which band I?m on. The problem seems to happen when the rig is first turned on and then may go away. I saw the problem when operating last night and when I tested the rig this morning on a dummy load it, re-occurred for a short while, then went away. A couple of weeks ago ran SS CW with the K3 running QRP and didn?t notice the problem. Before I box up the K3 and ship it to Elecraft, I am looking for ideas of what else to check. Although I built the K3 from a kit I haven?t had it open in years. I did send it to Don, W3FPR, to update the synthesizer boards and install the 2nd receiver about a year ago, but that was the last time the rig was opened up. The problem is very recent I am not sure if having 2nd RX will require much more disassembly in order to get to any connections related to the PA. I am rather hesitant to open the rig up. My workbench space is rather limited now and I don?t feel as confident with the dis-assembly as I was when I built the K3. Any suggestions appreciated.

The IC718 was introduced in 2000 or earlier and it is still sold. I think the 7300 is wildly successful (not trying to start a flamewar, but it is the best selling rig at many dealers) and they likely have economies of scale, parts get cheaper as you buy more, and they push the price down after the early adopters have bought, to better compete and drive out the competition.

I built my K3 kit in 09 and sold it to a friend who wanted another K3 to match his other two K3's. I wanted a K3s so applied that sale to buying the K3s, moved over that which was worth doing (upgraded Sub RX/filters and a few other things and upgraded the rest so it's now a current K3s. Add to that that I then bought a very early K3 from a nearby ham for my backup rig and I am a solid believer in Elecraft and their upgrade policy. Considering how the other radios on the market are not upgradable, I can not imagine any reason to ever buy one of them. As long as there is Elecraft, I will buy the next radio that has something new to offer. As someone sent to me not long ago... Why not buy it now, while you can, you're going to be a SK for a very long time...

Upgrading to the new synth boards and new transverter board with the built-in preamp for 12-10-6M, bringing it up to about 90% of a K3S for a small fraction of the cost of a new rig. With any other mfr, I'd have to sell the rig for half-price or less and buy a new one. The modularity that allows us to buy only the features we need, adds features provided by new hardware designs, and provides that inexpensive upgrade path is a big plus.

With the K2 you could get a new MCU chip, I don?t recall if there was one for the K1. But with the Gen 2 radios and their ability to take a MCU and/or DSP update it is over the top. I knew a few of the guys at Amateur Electronic Supply before they failed. They used to wonder why I stopped shopping there. Well YeaIcoKen didn?t give me what Elecraft could. An example would be the latest remote control of the KX2. Funky cool, and works as described. (Wayne - it needs a key sequence to take it out of remote control and restore panel operation without a power down.) Do you know of another ham radio manufacturer that can do that? I don?t either.

This would be fairly easy to add. However, it is only a limited parametric controller; see page 28 of the KX3 manual. K3-to-K3 remote control mirrors the front panel directly. For that you need a K3, K3S, or K3/0-mini at the control end. In either case, audio streams and the keyer paddle must be handled separately. 73, Wayne N6KR > On Nov 29, 2017, at 8:42 PM, Igor Sokolov wrote: > > Has this question been answered? > > I did search the reflector but could not find an answer. > > > 73, Igor UA9CDC > > > 21.07.2017 22:59, Matt NQ6N ?????: >> I seem to recall this being discussed with the KX3, but I haven't been able >> to find the relevant discussion. >> >> I'm curious if the KX2 can be used to control the K3 remotely in the same >> way that a K3 can be used to do so.

Yes, this is only about 1 dB, but it did help me snag XF1IM this morning on 20 CW. We consider the change experimental at this point.

Although when mounted outdoors, the manual tuning may make it difficult to tune from the KX2 location - so put on a short length of coax, and carry the KX2 to the antenna location for tuning. After tuning, connect a coax extension onto the antenna, and go into the shack for operating. 73, Don W3FPR On 11/30/2017 11:22 AM, Paulette Quick wrote: > What is the experience of operators with the KX2 indoors.?

Band conditions and timing is everything Have fun!!!!!! 73 de Ben W4SC From ctate at ewnetinc.com Thu Nov 30 13:05:09 2017 From: ctate at ewnetinc.com (Chris Tate - N6WM) Date: Thu, 30 Nov 2017 18:05:09 +0000 Subject: [Elecraft] KX2 max output now 12 watts (experimental) In-Reply-To: References: Message-ID: <236350B81BC09D42B8C3B41A97C654DD1FDCEEB0@AUSP01DAG0504.collaborationhost.net> Wayne I will load it on my KX2 and test.. ________________________________________ From: elecraft-bounces at mailman.qth.net [elecraft-bounces at mailman.qth.net] on behalf of Wayne Burdick [n6kr at elecraft.com] Sent: Thursday, November 30, 2017 8:13 AM To: Elecraft Reflector Cc: KX3 at yahoogroups.com; QRP-L; HF Pack Pack Subject: [Elecraft] KX2 max output now 12 watts (experimental) The latest KX2 field-test firmware allows power output to be set as high as 12 watts on 80 through 20 meters. (Max out is still 10 watts on 17-10 meters.) Supply voltage must be 12.8 V or higher on key-down. ~14 V supply recommended. Yes, this is only about 1 dB, but it did help me snag XF1IM this morning on 20 CW. We consider the change experimental at this point. Not all KX2s are guaranteed to hit 12 W on all of these bands, and this level is recommended for low duty-cycle use, i.e. hunt/pounce. If you?d like to give it a try, please email me directly. 73, Wayne N6KR ______________________________________________________________ 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 ctate at ewnetinc.com From stevesgt at effable.com Thu Nov 30 14:19:51 2017 From: stevesgt at effable.com (Steve Sergeant) Date: Thu, 30 Nov 2017 11:19:51 -0800 Subject: [Elecraft] Experience with KX2 indoors In-Reply-To: <1951035035.4736391.1512058963871@mail.yahoo.com> References: <1951035035.4736391.1512058963871@mail.yahoo.com> Message-ID: I often use the KX2 indoors with one of two temporary antennas: 1) A 3.9, 7.2, and 14.3_MHz 76' trapped and coil-shortened center-fed inverted-V (dipole) with a SOTAbeams 1:1/15W balun, pitched on a 10m MFJ "fishing pole", and terminated on some 6' wooden fence posts. This connects to my shack using a 75' length of RG58. 2) A 36' helical-wrapped vertical wire on that same "fishing pole", five random non-resonant radials varied between 12' and 33' long at 6 to 12 inches above the ground, and a SOTAbeams 4:1/15W balun. I use this on 7.0 through 29.7_MHz. This connects to my shack using a 35' length of RG-8x. With this setup I have worked 47 states and 3 Canadian provinces on JT65, and 8 states on SSB. I regularly check-in to a couple of multi-state public service nets on 75m as well. I also carry those same two antennas into the field for camping trips, but instead of RG58 or RG8x, I carry a 60' piece of RG174. Around the time of the recent solar eclipse, I made about 20 contacts in 3 hours from my campsite in Idaho outside Yellowstone N.P. with stations from the west coast all of the way to the Great Lakes region on 80m and 20m. When I used the KX2 with a Chameleon "P Loop" I was underwhelmed with the results.

Further playing with the controls showed a similar noise bar just above the low cutoff. Note that these noise bars are in the requested pass band. Has anyone else observed this noise?

The antenna was sitting on a table near the window and I worked quite a bit of DX, including Tunisia and United Arab Emirates.? Being the only entrant in the 20M QRP category, I naturally came in first place.? Prior to the contest I worked many additional stations including Aland Islands at 10 watts.? Of course, propagation was a bit better than is currently the case. Caveat: This was the Elecraft version of that antenna (no longer available) which had the loading coil painted in Elecraft grey, which obviously added some additional mojo. I'm planning on setting up the same antenna for use with my KX2 from my ground level apartment but don''t expect quite the same performance.

When I turned off the "Flatten" option in the waterfall window, the noise bands went away. What I think is happening is that the algorithm in wsjt-x that flattens the response for the window sees the total lack of energy outside the K3's selected band and boosts the levels of the signals and noise near it as part of its compensation strategy. 73 Bill AE6JV On 11/30/17 at 2:11 PM, frantz at pwpconsult.com (Bill Frantz) wrote: >I have a K3 which has been upgraded to have the Elecraft internal USB sound card. > >I tried adjusting the DSP bandwidth when running FT8 to >eliminate a strong signal above the FT8 subband and noticed >that there was a strong noise bar on the water fall for about >400 Hz below the high cutoff.
