I am not an expert on this, I AM an expert on this. :) The most important place for a choke in any antenna system is at the feedpoint. It's function is to prevent the feedline from becoming part of the antenna by adding a very high common mode impedance to the common mode circuit. The only good reasons for a choke elsewhere along the line are 1) to prevent the feedline from becoming a parasitic element of another antenna; for example, I choke the coax feedlines to my high (125 ft) dipoles for 80 and 40 so that they do not become parasitic to my three 160M verticals. e 2) to prevent coupling shield current by a mechanism quantified as the "transfer impedance" of the coax shield. It is the ratio of the differential voltage generated inside the coax as a result of shield current. Its unit is Ohms, lower is better, and the lower limit is the RF resistance of the shield at the frequency of interest. But the quality, density, and uniformity of the shield makes an additive contribution -- a poor quality shield increases the transfer impedance. Both of these measures minimize inter-station interference, both in-band and cross-band. W6GJB's contesting trailer has antennas for 15, 20, 40, and 80 supported on a single pneumatic mast, with their feedpoints within about 2 ft of each other. Because they are very effectively choked, and because we have dual stubs on the outputs of the power amps for the two stations, we can operate on adjacent bands at 500W (K3/KPA500) with minimal interference from the lower frequency station's harmonics to the higher frequency station. One day, Glen rebuilt the connection at the antenna and accidentally left out the choke, and the interstation interference was terrible. A choke at the rig is only a band-aid for failure to do proper grounding and bonding in the shack and throughout the house. See N0AX's ARRL book on the topic, on which I collaborated, or the slides for my tutorial talk at Pacificon, Visalia, and to various ham clubs. http://k9yc.com/GroundingAndAudio.pdf The half-wave section of line you described in an earlier post may take care of the feedpoint for one band (and it may not be as effective as a well-designed choke), but it's not a solution for other bands. Properly designed chokes can cover multiple adjacent bands.

Tested with K3 Utility with same result. Tried a different USB/RS232 cable, still not communicating. Troubleshot 9-pin receptacle and discovered the ground pin was not grounded. Pulled out the KIO3A and found the chip inductor on the ground line had blown up open ckt. Removed it and substituted a wire jumper (still not working). At that point I was going to have to rig up a test cable to be able to troubleshoot the module unplugged from the K3. Instead I sent it to Elecraft Repair. They had it for 28-days and then replied that a new digital board was needed as the existing board was not reparable. They are on order. I did have the option to buy a KIO3B but that was over $400 before shipping (and also not in stock) I don't need or use the USB port. I worked 1966-2009: ten years as an RF engineer, and the rest as technician doing SM level troubleshooting/repairs. After retiring I had a small business building transverters and amplifiers from kits (all SM). I have a pretty decent workbench and test equipment to 26-GHz. II could have spent the effort in building a test jig and trying to troubleshoot on my own. I figured it easier to let the experienced staff at Elecraft do it. Hoping to get my KIO3A repaired when board order arrives. I've decided to set up my KX3 for computer modes using a Rig Runner NOMIC I/F. I'll post the project on my website when done. The KX3 will use WSJT-X for running JT65B on 2m-eme by driving a 2m transverter. on 28-MHz with 3w. 73, Ed - KL7UW ----------------------------------------------------- You can view the Schematic diagrams (6 pages) for the Elecraft KIO3B module. https://ftp.elecraft.com/K3S/Manuals%20Downloads/E740323%20K3s%20Schematic%20Files.pdf The KIO3B is a multi-function module, that includes these functions: 1. RF Board interface 2. Digital I/O interface 3. Audio I/O interface 4. USB, Codec, RS232 FTDI FT232R (USB), TI PCM2901 (CODEC), TUSB2036 (2/3 port USB hub) 5. Digital I/O 6. Audio I/O == It is NOT impossible to repair or troubleshoot (component-level), BUT it can be time consuming for the novice or weekend technician. This is why Elecraft stated ?economical? (their bench time is NOT Free). ? Sage advice from my high school electronics instructor, WB9FUR (sk, 2016) has served me well : External event (ESD, Over-voltage, Op error) and I/O ports are major causes of module or circuit failures. Electronic devices rarely ?die? for no reason (assumes QA production of part). ? ?What functionality? has failed will narrow the circuit areas and components to examine. IF you can ?think thru? those observed symptoms, many failures can be pinpointed with a DVM to a few key components.

I have more recently added the KSB2 SSB adapter and have noticed my voice is either very high-pitched or low-pitched on an external receiver while using a 50-ohm dummy load. After spending some time on the issue of SSB voice on transmit, I realized that if I mistune the K2 on transmit that my voice would appear to sound normal with no humming on an external receiver. The following are examples: 10m 28529.45u from K2 to external receiver set at 28530.00 (-550 Hz on K2 side) 12m 24939.19u from K2 to external receiver set at 24940.00 (-810 Hz on K2 side) 15m 21229.30u from K2 to external receiver set at 21230.00 (-700 Hz on K2 side) 17m 18119.35u from K2 to external receiver set at 18120.00 (-650 Hz on K2 side) 20m 14159.70u from K2 to external receiver set at 14160.00 (-300 Hz on K2 side) 40m 7149.75L from K2 to external receiver set at 7150.00 (-250 Hz on K2 side) 80m. 3750.30L from K2 to external receiver set at 3750.00 (+300Hz on K2 side) I have previously adjusted C22 using an external frequency counter on TP3 along with the K2?s frequency counter probe to get the readings from both the external frequency and K2?s to match. And yes, I?ve adjusted the filter and BFO settings per the KSB2 operating instructions. I would welcome any suggestions to get a resolve to this problem. 73, John - KF6QPC From jim at jtmiller.com Mon Nov 2 10:51:37 2020 From: jim at jtmiller.com (Jim Miller) Date: Mon, 2 Nov 2020 10:51:37 -0500 Subject: [Elecraft] K4 Remote Antenna button Message-ID: This is mentioned in the online manual.

You can do that in receive. It is best if you do that using a visual aid like an audio spectrum analyzer to be able to see the position of the filter passband in the audio spectrum. Spectrogram is one such analyzer - it runs on your computer and soundcard. Non-Windows folks will have to find some other program. To see how to set up and use Spectrogram 5.17 download the .pdf at http://www.mmccs.com/mmarc/n0ss/k2_filters_using_gram_v5r17.pdf. You can download Spectrogram from my website www.w3fpr.com. On the home page, scroll near the bottom to find the links. Both versions 5.17 and 16 are there. 73, Don W3FPR On 11/2/2020 10:45 AM, JOHN CAPEL via Elecraft wrote: > Hello Elecraft Community, > > I have recently built the K2/10 and have enjoyed listening to the receiver.

Eric and Wayne were authors of the design and updated the schematic (at least according to mine dated 2017). One of them may be able to tell us. The MCU type is listed in the schematic, but without knowing how big the memory block is, it is hard to tell what of the memory could be written to in the EEPROM area. Hopefully one or other will chime in and let us know.

The earpads for my Sony MDR7506 phones are user replaceable, but the cable is not. I've owned several sets of them that I've used for many years, and never had a problem with the cord, but I did buy a set for $5 at a ham flea market with a bad cable. :) Some of the German headphones have user replaceable cables, especially those used for stage intercom and by broadcasters, but they're not nearly as comfortable, don't sound nearly as good, and are fairly exp0ensive. Beyer, AKG, and Sennheiser make some very nice phones -- they're first rate manufacturers.

Due to the transient nature of Meteor Scatter bursts/pings, the best AGC setting is OFF, as the AGC would flatten the signal, potentially impacting decoding. In MS we RX 30s and send the next 30s; the weird behavior I'm observing is that the RX audio level on the USB souncard output is varying between RX periods, i.e. the AF level changes up and down (around 10dB) between different RX periods. The AF level stays the same within the same period. I initially suspected some relay issue (PA / LNA) but I've tested everything including a different receiver with AGC off and the problem is definitely the K3. Any hint what may be happening ? I've tried changing the AF Lim value but that only seems to have an effect on the Loudspeaker audio, not on the USB soundcard. 73 Marco HB9CAT From pincon at erols.com Mon Nov 2 22:29:37 2020 From: pincon at erols.com (Charlie T) Date: Mon, 2 Nov 2020 22:29:37 -0500 Subject: [Elecraft] CM-500 Message-ID: <00ee01d6b191$92b57c70$b8207550$@erols.com> I'd highly recommend Velour pads as opposed to OEM or equivalent that start flaking way sooner than you expect.

Take the new ear cushion and Stretch the part that will go in the slot Then working quickly (before it stretches back) work it into the open slot. On the side with the cord you may need to remove the bottom screw to get enough clearance for the strain relief for the cord to fit. Retighten the screws and you are done.

I like all three for different reasons. The CM-500 is comfortable, and has the best mic boom, it has an enormous output from the electret mic ? nearly too much for my K3. I used it effectively with the K2. The SB-45 is very comfortable but has a flimsy mic boom that tends to wiggle when I move my head. I can wear it for hours. The Heil Proset has the best frequency response in the headphones, and has an HC-4 element, which is unobtanium today. My problem with it is it hurt my ears after wearing it for an hour. I fixed that problem recently by buying some oversize earopads from Brainwavz. It is now just as comfortable as the CM-500 or SB-45. > On Nov 1, 2020, at 5:31 PM, Jack Brindle via Elecraft wrote: > > I bought a new CM-500 set on Amazon about two years ago.

They feel very similar to my Heil headset, meaning about the same as putting my head in a vise. Simply too tight on my head, especially for wearing them through a 48 hour contest.

I've read various messages here on pad replacements for these and other headphones, comments on various pad types including OEM vs velour, etc. The one thing I'm stuck on that this point is that, on vendor sites like Amazon, I see reviews where it's mentioned that pads can cause a significant change in the headphones' sound.

They're not the cheapest, but you can buy Sony-branded pads. Search on Sony MDR-7506 replacement earpads.

In a light wind, it tends to take off. I adjusted the band in the back, etc. and the only thing I can come up with is the hat is not as preformed as the old had was. So I thought it must be that the material is thinner or something. Even though they are the same brand and look identical inside, they are made in different countries. So they are different.

For ham radio, go with comfort -- bass response is something we don't need (or want). Music is a different story -- go with comfort AND bass response. Ear pads affect low end (bass) response by improving the air seal between the phones and the head. It's also improved by a headband that clamps the phones more tightly to the head. 73, Jim K9YC From patrick at skerrett.net Thu Nov 5 15:18:04 2020 From: patrick at skerrett.net (Patrick Skerrett) Date: Thu, 5 Nov 2020 14:18:04 -0600 Subject: [Elecraft] KAT500 in Bypass @ Legal limit Message-ID: Hey guys, I have a need for a while to use an automatic antenna switch on fully resonant antennas.

I use several different sizes of the Bioenno LiFe batteries (see earlier threads this summer for a detailed discussion), and I vote to use the proper charger. It's only a few bucks more...on the road, I use an inexpensive converter to power the charger for the LiFe batteries. And I recall being surprised by someone writing about a specific Li-ion battery that they got good service from. I don't usually vote for that technology, but the OP had good luck with it. My opinion, tech-based, but still my interpretation of the data, is that Li batteries are generally over-charged, leading to hazard conditions, especially for lower quality batteries, and much shorter battery life. Please look for the thread, because there was a lot of good discussion there.

The voltages and currents are targeted specifically at 3 Li-Ion cells (11 V). Just to give you another [probably biased, beware] opinion on the KXBT2, though: The internal battery isn't just about powering the radio, it's about mobility. It facilitates the kind of adventurous, ad-hoc, pedestrian mobile operation that many KX2 users engage in. (Speaking strictly for me :) As a battery, the KXBC2 has proven safe and reliable by thousands of users. It's about 2.5 AH at 11 V, considerably higher in energy density than the battery packs in its closest competitors. I typically get 2 or 3 hours of hunt 'n' pounce operation at 10 watts. Eventually the radio will drop power to 5 W and carry on for another 2 to 3 hours. 73, Wayne N6KR > On Nov 6, 2020, at 4:26 PM, Rich NE1EE <73.de.ne1ee at gmail.com> wrote: > > Hi Bob, > Well, to get the ball rolling, I'd say no to the KXBC2.

Bioenno products are LiFePo, a different kind of LiOn Chemistry than the Elecraft ones. The Bioenno charger will work for all the higher AH batteries they sell that have the DC Barrel connector. (I think that's up to 12AH). That Bioenno charger provides 15V 2A until the battery voltage reaches a certain level and then to a trickle charge level of .2A. I highly recommend 12AH battery for QRP use as well as field charging an HT. They are pricey to start but they provide 12V or better for the entire AH rating and are intended for 1000 or more full charge/discharge cycles. The life cycle cost is therefore lower than other batteries. I get a full 15W from my KX3 with the 12AH3. -73- W1GCF From tim.n9puz at gmail.com Fri Nov 6 23:30:04 2020 From: tim.n9puz at gmail.com (Tim McDonough N9PUZ) Date: Fri, 6 Nov 2020 22:30:04 -0600 Subject: [Elecraft] KX2 External battery question In-Reply-To: <1514540751.3068790.1604703990942@mail.yahoo.com> References: <1514540751.3068790.1604703990942@mail.yahoo.com> Message-ID: The 12V Bioenno batteries have an internal battery management circuit.

Kenwood, Yaesu and Ten-Tec transceivers do not provide bias for an electret mic at all. To use an electret mic with those transceivers one needs to install a "power adder" (5K6 Ohms resistor between pin pin 5 (Kenwood) or pin 2 (Yaesu/Ten-Tec) and the tip of the CM500 and a 1 uF capacitor in series between tip of the CM500 and pin 1 (Kenwood) or pin 8 (Yaesu/Ten-Tec)) unless one is using the Yamaha "battery box." 73, ...

The fact that bias is needed confirms that the "key element" is an electret. Ignore the packaging statement about dynamic, which has been wrong for a couple of decades. The original CM500 did have a dynamic element, but a change was made for reasons not in evidence. Someone forgot to tell the marketers and packaging folks.

The CM500 has had an ELECTRET mic as far back as 2008, when W6XU, another audio professional, arranged a group purchase for your Bay Area contesting club. It DOES need Bias, which most modern rigs provide on one pin of their mic connector. Simply adding a resistor of suitable value (in the range of 5-10KOhms) between that pin and the mic input pin, provides bias suitable for most electret mics. 73, Jim K9YC From Lyn at LNAINC.com Sun Nov 8 06:51:49 2020 From: Lyn at LNAINC.com (Lyn Norstad) Date: Sun, 8 Nov 2020 05:51:49 -0600 Subject: [Elecraft] [Elecraft-K3] Winlink In-Reply-To: <23923908-3d2e-0258-16db-5a1d92b3789e@nk7z.net> References: <3d635594-48e3-8348-a762-ae408173d56e@nk7z.net> <138701d6b536$c1068620$43139260$@verizon.net> <23923908-3d2e-0258-16db-5a1d92b3789e@nk7z.net> Message-ID: <1ffa01d6b5c5$8b3d6650$a1b832f0$@LNAINC.com> Dave - Windows 10 attempts to lock down USB port assignments as a security measure, and does so again with each update. Some apps are smart enough to deal with this, but Winlink is basically a 1990s era Email application and is susceptible to issues like this. There are numerous articles on how to deal with it. Some that want to sell you an app to fix it, some that tell you how to fix it yourself (i.e.: The Windows Club website). Select the one that best matches your comfort level. Worst case scenario, you fix it manually after every Windows update. But at least you are aware of what needs fixing, and how to do it. In most cases, you need to go into the Soundcard settings for the Mode you have selected (i.e.: Vara HF Winlink) and change the input and output devices to USB Audio Codec.

I have Voicemeeter Potato installed, so my output is the computer's speakers (currently sent to headphones), and the mike input comes from a Zoom H4n Handy Recorder in USB interface mode. The radio doesn't supply power, the USB on the computer does. If I had to hook it direct, I'd make a custom cable for the mike input, XLR to 3.5mm, or at worst, 1/4" phono to 3.5mm. The H4n has, in addition to built-in mikes, XLR in/out with integral 1/4" sockets. Then I'd put batteries in the H4n to supply its power. The H4n also has a 1/4"x24 stud mount, so it can be connected to a tripod, a cold shoe for a video camera, or a mike stand adapter to fit a standard mike stand or boom. That's how I have it set up right now, with an On-Stage extendable arm, clamped to the upright pipe of the wire rack next to my chair that I use as my "shack stack". The built-in stereo mikes are electrets, of course, but they're GOOD electrets. The H4n is prosumer gear bordering on professional grade, with VERY good sound. I get a lot of compliments on the SSB output of this setup. -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Sun, Nov 8, 2020 at 4:27 AM Jim Brown wrote: > On 11/7/2020 2:42 PM, Bill Frantz wrote: > > The packaging said (in part), "Dynamic Microphone for Active Musicians" > > The sales/marketing department, usually ignorant of what they're > selling, wrote that drivel you're reading, which is intended simply to > sell more of whatever they're selling. > > The CM500 has had an ELECTRET mic as far back as 2008, when W6XU, > another audio professional, arranged a group purchase for your Bay Area > contesting club.

So it needs that power. Well, electret microphones certainly need power to run their internal amplifiers. Some other microphones (e.g. condensor) also need power, which is why pro audio systems have phantom power over their audio cables. It very probably isn't a dynamic mic, although someone might build a dynamic mic with a built-in amplifier which would only work with external power. YMMV! However, given the electret microphones are very cheap and are good quality, I'd bet on electret.

I have a very similar arrangement with the KPA/KAT500 and three wired Kidde smoke/ CO detectors. I've had problems with it periodically over the years in spite of various attempts to resolve triggering the smoke detectors using various ferrite cores and bypass capacitors and being as fastidious as I can with grounding in the shack. Glad to hear it's working well in your shack ;-) I'd be interested if anyone has experience running some power with the new wirelessly interconnected Kidde detectors that create their own rf based interconnection rather than use the wifi system that may already be present in the home.

To use an electret mic with those transceivers one needs to install a "power adder"". Actually they do provide bias to their own line of electret mics, so you could have been a little more specific and said "for non-OEM mics". We can't tell what you are thinking when you type.

I only run 100 watts, but occasionally triggered alarms on 160 meters where my vertical is only 30 feet from the house. I replaced all detectors with First Alert units which come with a 10 year back up battery. Never any trouble with the Kidde or First Alert units on 80-6 meters. I never installed any ferrite or ran a high power amp so no idea how they would respond to 1KW plus. The First Alert units do not have the voice warning, but give coded beeps for fire and CO. I tried one unit first, then since my old ones were 7 years old, just replaced them all. This is not a scientific test with a sample size of ONE. Just an idea to try, and my new units have only been installed less than 2 years. Good Luck.

Recently my K3 has experienced a couple of issues. I have been unable to get a response from Elecraft e-mail or telephone service regarding the situation. It's been almost two weeks now so thought I'd ask here if anyone has some suggestions for me to try myself. Here is the main concern: When getting ready for CQWWDX SSB a few weeks ago, I went through setting the transmit power on each band to drive an amplifier properly. The power display seemed a bit sluggish and had a delay in indicating the SWR. Worse yet, when I got to 40M, I could not crank the power up past about 30 watts; it would momentarily display a higher number but then fall back to 30w. All other bands cold be set higher. First I reloaded all the current firmware in the main and subreceiver. No change to 40M. So next I went to the K3 Utility ver 1.20.1.15 to do a transmitter gain calibration. Starting with the 5W calibration, it stepped thru the first few bands OK but then stopped (I think on 40M) and displayed "ERR TXG" and the message "calibration settled at 3.6W, TX gain failed because transmit power did not reach the expected value". In anticipation of having to send the radio to Elecraft where it might be totally reset, I manually started recording all the configuration settings. When I looked at my filter settings, I was shocked to see that filter 1 in the subreceiver was set to 1.35. Huh? It should have been 2.80 !! Was my config info corrupted? I reset that to 2.80 and then for the heck of it tried again to set the power on 40M. That now worked "OK" and the swr and pwr display during "tune" showed instantly on all bands. Something had changed. Next, I decided to rerun the TX calibration gain routine. This time if successfully completed the 5w and 50w routines. However, with a good dummy load, 40M displays an swr of 1.4, while the other bands are 1.0 or 1.1, so something is still a little funny on 40M. What might that be? I have now been considering doing a total reset of the radio using the EE INIT function and then the self calibrations. Is this wise?

Do you have an original KAT3 tuner installed in the K3? If so, it is likely that the "bypass" setting has become corrupted on 40 M. Enable the tuner, connect the rig to a good quality 50 +/- j0 dummy load and TUNE into the dummy load then bypass the tuner and check the SWR. That should reset the bypass settings. 73, ...

It worked for me after changing the LPA FETs in my K3. 73, Scott AD5HS ======================================================= You'll need this sequence for setting bias after the fix: *Here is the procedure to check if your LPA module has been adjusted properly for bias current:* (current increases approx. 600 ma when XMIT is tapped (below 12W). 1. Remove the 100 watt amplifier (if installed) by disconnecting the fan panel and their 2 connector wires, and the 2 wires to the circuit breaker. Use care to not pull on the KPA3 too hard and thus let it fly off the connectors and cause damage to it or to the chassis. Use gentle but firm finger pressure, or pry carefully with a plastic tool (such as the K2 green plastic alignment tool), near the two PCB connectors. This will usually help the KPA3 start to move. 2. Locate small SMD pots R18, R19 and R24 near the center of the LPA board. Turn the pots to minimum. (White pots fully CW, Black pots fully CCW) 3. Turn the power knob down to ZERO. 4. Tap DISP, (display button), use VFO B to display the current drawn by the radio. For more accurate results, insert a DMM in the positive power supply lead that is set to a current range that can handle up to 2-3 amps. 5. Hold TEST (the right hand side of the MODE button). This puts the K3 in TEST mode with no RF drive. 6. Tap XMIT. You will see a current of approx 1 to 2A (depending on options in radio) but the red TX LED will not come on. Adjust R18 to increase the reading by 0.2A IE 200ma 7. Adjust R19 to increase the current another 0.2A 8. Adjust R24 to increase the current another 0.2A 9. Tap XMIT to exit bias on condition. (Current should drop approx. 600ma). NOTE: if you are just checking current and you do have the KPA3 installed, set it to NOT INST and cycle power so you do not have its current added, thus confusing your readings. 10. Set Power to 11.9W. Hold TEST again to cancel TEST mode so RF output is possible. The LCD shows TX NORM. 11. With PWR SET to ?nor? Hold TUNE and see how much power you get on all bands.

Message-ID: <000001d6b959$6d779630$4866c290$@com> All of these MDR-7506 posts reminded me that I purchased OEM pads for my Sony MDR-7506 many months ago but I never installed them. I had some free time this evening and I was still able to find the ear pads in my "stuff" so I thought I would give it a try. It was quite easy to remove the original pads. To install the new ones I started at the top (not the side) and did not push the material very far into the lip. I worked my way to the bottom holding the pad lip in place along the sides. When it was completely around I used a thin machinists scale to push the pad into the groove in areas where it was not seated properly. It was a little time consuming but not really difficult and now the headphones look new again. These are my favorite headphones! John KK9A Frank O'Donnell K6FOD: Is there a secret trick for getting replacement earpads installed smoothly onto the headphones? I bought a pair of Sony pads for my MDR-7506, but try as I might, as I get one side into the groove on the headphone, the other side inevitably slips out. Beginning to get into the realm of the comical.

However, the 2m Wx radio sensitivity differs by 1.5 S units between the two, same parameters set. The preamp is on and set to 20dB on both. Any ideas?

The NXP 1K50H devices are only biased at 1 amp each which is a bit low for optimal IMD as it is. SSB IMD could be improved by increasing bias to 2 amps per device. Since the bias is only present during TX the waste heat increase would be negligible. The FLex Power Genius XL uses same RF devices and they use 2 amps per device @ 52 volts on SSB. IMD at that spec on PG. L is very acceptable. I am sure there is a reason I am overlooking for the Elecraft engineers to adjust bias to 1 amp per device.

Occasionally the KPA power indicator shoots up to 700W, and the KPA faults. When I clear the fault, the KPA is in STBY, and if I send a dash, I see the 100W LED come on. if I then put the KPA in OPER and send a dash, USUALLY I get the expected 250W output, but occasionally it shoots up to 700W and faults again. Now for the second scenario. With the KPA in OPER and outputting 250W, I switch it to STBY, then send a dash. I expect to see the 100W LED, but it does not light. If I look at the K3 RF bar graph, it shows 10W, not 100W. If I slightly turn the K3 PWR knob, it shows about 10W, not 100W. Until recently, the K3 ALWAYS switched back to my normal setting of 100W when the KPA is in STBY. The fact that it occasionally remains at 10W seems to indicate that it doesn't know the KPA is in STBY. Furthermore, the first scenario, where the KPA output shoots to 700W and it faults, seems to indicate that the K3 is sending it 100 watts -- another indication that the K3 doesn't know the KPA is in OPER, and thus doesn't reduce its output power to 10W. Is there any way to diagnose this problem, and more importantly, to fix it?

My main antenna is also an OSCFD and not really cut for 80 metres, so the SWR is always a bit higher than I prefer, possibly approaching 2:1. My setup is a K3S + P3, KPA500 and KAT500. A couple nights ago I was attempting to call a special event station in a pileup on 80 metres and decided to turn the KPA500 on. I was only running with around 11W from the K3S, giving me about 200W output from the KPA500. After 'shouting' a couple of times, the SWR was just below 2:1 but the KPA500 didn't like it and suddenly faulted. When I tried to TX barefoot from the K3S, there was no output - nothing showing on the K3S display. I checked the power setting and it was 100W. I had previously power cycled the KPA500 and it was in Standby. The only way I could get the K3S to TX was to power cycle it, then all was back to normal. I ran the KPA500 in Operate again for a few moments to check that it was OK and all seemed normal, but I didn't pursue it on 80m because I didn't want to push my luck. :-) A couple days later on a regular 40 metre net, I ran the KPA500 again for over an hour (on SSB) and have had no issues. I've not checked the manuals as to whether the original action is a safety feature or a bug. 73, Alan.

Recently my K3 has experienced a couple of issues. I have been unable to get a response from Elecraft e-mail or telephone service regarding the situation. It's been almost two weeks now so thought I'd ask here if anyone has some suggestions for me to try myself. Here is the main concern: When getting ready for CQWWDX SSB a few weeks ago, I went through setting the transmit power on each band to drive an amplifier properly. The power display seemed a bit sluggish and had a delay in indicating the SWR. Worse yet, when I got to 40M, I could not crank the power up past about 30 watts; it would momentarily display a higher number but then fall back to 30w. All other bands cold be set higher. First I reloaded all the current firmware in the main and subreceiver. No change to 40M. So next I went to the K3 Utility ver 1.20.1.15 to do a transmitter gain calibration. Starting with the 5W calibration, it stepped thru the first few bands OK but then stopped (I think on 40M) and displayed "ERR TXG" and the message "calibration settled at 3.6W, TX gain failed because transmit power did not reach the expected value". In anticipation of having to send the radio to Elecraft where it might be totally reset, I manually started recording all the configuration settings. When I looked at my filter settings, I was shocked to see that filter 1 in the subreceiver was set to 1.35. Huh? It should have been 2.80 !! Was my config info corrupted? I reset that to 2.80 and then for the heck of it tried again to set the power on 40M. That now worked "OK" and the swr and pwr display during "tune" showed instantly on all bands. Something had changed. Next, I decided to rerun the TX calibration gain routine. This time if successfully completed the 5w and 50w routines. However, with a good dummy load, 40M displays an swr of 1.4, while the other bands are 1.0 or 1.1, so something is still a little funny on 40M. What might that be? I have now been considering doing a total reset of the radio using the EE INIT function and then the self calibrations. Is this wise? Any experiences or suggestions appreciated. 73, Chet, N8RA ______________________________________________________________ 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 k9yeq at live.com From jim at n7us.net Sat Nov 14 11:31:42 2020 From: jim at n7us.net (Jim McDonald) Date: Sat, 14 Nov 2020 16:31:42 +0000 Subject: [Elecraft] K3S RX OUT Message-ID: Can an SDR, such as a SDRPlay RSP1A, be connected to the RX OUT jack on the K3S instead of using the IF OUT (on the radio or the P3)? 73, Jim N7US From g4gnx at g4gnx.com Sat Nov 14 11:38:24 2020 From: g4gnx at g4gnx.com (Alan - G4GNX) Date: Sat, 14 Nov 2020 16:38:24 +0000 Subject: [Elecraft] K3S RX OUT In-Reply-To: References: Message-ID: There's no reason why you can't do this.

The left channel will be VFO A and the right channel will be VFO B. Using the USB connection means you don't need a "sound card" to digitize the audio.

Then I checked WWV 10MHz I was about 230 Hz off frequency based on PX3 display. Looking at the 10MHz signal from the function generator, I was off by the same amount based on PX3. I adjusted the REF CAL setting to get both the 10MHz WWV and Function Gen 10MHz centered on the PX3 (same REF CAL setting). I checked with my old HP8640B at 10MHz, it was within 20Hz. With WWV I could see both the center and side bands, I was using the center as my reference. The manual states that following it's procedures accuracy should be within +/- 1 ppm.

The KPA1500 chooses the most recently stored ATU setting in the new ?bin?. On transmission, if SWR exceeds a threshold, and a KPA1500 config choice for HiSWR retune is enabled, other ATU settings in the bin are evaluated. This requires a bit of RF. Once the best ATU setting is found, the bin is reordered and stored, so when you return to this frequency, the most recent setting is tried first. If you mostly use your three antennas on the obvious bands, there should be one or two ATU settings per bin. If you train your 80 meter dipole on 20 and your 40 meter beam on 15, there may be more ATU settings per bin. I?d consider putting the HyTower on the second ant port so that it can be used on all bands without having to search thru settings for the ?other? antenna. If there are any ATU settings in the bin, only those settings will be tried, so tune in every bin if you have multiple antennas. It takes on the the order of 20 milliseconds of stable RF per ATU setting, which has to do with relay settle delay and reevaluating SWR. A CW dit at 30 WPM is 40 mSec. ATU relays are changed after bypassing the PA momentarily, and that also takes a few mSec. 73 de Dick, K6KR > On Nov 15, 2020, at 08:51, Gary Slagel via Elecraft wrote: > > ?I'm thinking of replacing an old SPE amp with a KPA1500. > I have 4 antennas: 10/15/20 yagi, 40M yagi, 80/160 dipole and an all band hytower vertical so will probably have 3 switched antennas to one antenna port on the KPA1500 and 1 antenna to the 2nd antenna port. > After 'training' on all freq/antenna combinations I'll tend to have 2 or 3 settings for each freq/bin.

As long as each antenna presents a fairly low SWR to the tuner, you will be ok. If, say, both antennas are at or below 3:1 SWR when tuner is bypassed, at a particular frequency, you should be ok switching from one to the other while un-keyed & then keying up full power at the new ant setting. I train the tuner for each antenna separately after erasing any settings for that band. Then I only have two choices for the tuner to make. Even then, you may get a fault response if you tune to a freq where one antenna is way above 3:1 & the other is not and you key full power - I usually apply 'tune' power after a change of antennas & it seems to be ok. The tuner will match almost anything below 10:1 or so but you can't run full power with the higher SWR's. 160M is real picky above 4:1, 80-6M will still allow about 750W at 10:1. Take a look at the user manual on the Elecraft site for better info. It is the best amp I have used but you have to get familiar with it's limitations.

Yes. This can be done even with a basic K4, since it has independent left and right receive channels pertaining to VFO A (main) and B (sub). A K4D would give you the ability to use different antennas for the two receivers. It also optimizes performance when the two receivers are on different bands since it includes a second set of band-pass filters, preamps, and attenuators.

The KPA1500 chooses the most recently stored ATU setting in the new ?bin?.? On transmission, if SWR exceeds a threshold, and a KPA1500 config choice for HiSWR retune is enabled, other ATU settings in the bin are evaluated. This requires a bit of RF. Once the best ATU setting is found, the bin is reordered and stored, so when you return to this frequency, the most recent setting is tried first. If you mostly use your three antennas on the obvious bands, there should be one or two ATU settings per bin.? If you train your 80 meter dipole on 20 and your 40 meter beam on 15, there may be more ATU settings per bin.? I?d consider putting the HyTower on the second ant port so that it can be used on all bands without having to search thru settings for the ?other? antenna. If there are any ATU settings in the bin, only those settings will be tried, so tune in every bin if you have multiple antennas. It takes on the the order of 20 milliseconds of stable RF per ATU setting, which has to do with relay settle delay and reevaluating SWR.? A CW dit at 30 WPM is 40 mSec. ATU relays are changed after bypassing the PA momentarily, and that also takes a few mSec.? 73 de Dick, K6KR > On Nov 15, 2020, at 08:51, Gary Slagel via Elecraft wrote: > > ?I'm thinking of replacing an old SPE amp with a KPA1500. > I have 4 antennas: 10/15/20 yagi, 40M yagi, 80/160 dipole and an all band hytower vertical so will probably have 3 switched antennas to one antenna port on the KPA1500 and 1 antenna to the 2nd antenna port. > After 'training' on all freq/antenna combinations I'll tend to have 2 or 3 settings for each freq/bin.?

Check your data sub-mode (DATA MD) *one each band*. The sub-mode is stored *per band* and it would appear that yours is set to AFSK_A (LSB centered on the dial frequency) instead of DATA_A (USB). It is likely that the sub-mode on 15, 17, 12 is incorrect (probably because your logging/data program set it to AFSK_A when you last operated RTTY on those bands). 73, ...

The consensus seems to indeed involve a communication issue: the KPA500 sends a signal to the K3 when its operational status changes, but for whatever reason the K3 fails to see message. There is no expectation that the K3 will ?ACK? the signal from the KPA500. I have found it important to watch the K3 LCD to see that the operational change has actually been received and acted upon. If not, cycling the OPER switch on the KPA500 until you actually see the K3 is in the desired mode. Works every time?

I.e., if I hit send a dash, I get 10W output to the antenna. * KPA fault log - Indicates high SWR. My antenna has had some issues recently, and I am still working on that, so the KPA fault log is definitely relevant. I have connected my dummy load to the PL-259 that connects to the antenna's balun, and sent 500W to it. No SWR problems, but I will do this again before digging into the balun. So there are some things I still need to check. But first I want to try getting the antenna working right.

I regret greatly my purchase of the KXPD2 in 2017. It is the worst iambic key I've used in the past 40 years, with a bizarrely wide finger spacing that's twice that of the KXPD3 and all other iambic keys I've used. It permits adjustment of contact spacing only and not the important spacing between paddles. The paddle finger spacing is so wide as to be unusable. Mine arrived missing one of the set screws (not shown or listed in the instruction sheet) designed to lock the contact spacing set screws. The key came with a spare spring that is not described in the instructions (is it the same spring force as the installed spring?). The key requires two different Allen wrenches, but has a storage channel in the key frame for only one. The design should have used only one size Allen wrench for ALL adjustments. I suggest caveat emptor for the KXPD2 and the MH3, just as I did 20 years ago for the K1 KTS1 and KBT1. Everything else Elecraft that I've owned since 2000 has been great, except for the radiant heat-absorbing paint job on the KX2.

Thank you everyone on the K3 forums for your shared advice and experiences. The "3 screw" tests were pointing to a bad output transistor in the LPA. The idle current increase on the K3 meter when putting the radio into XMIT (not TUNE) was only 310 ma, where at least 600ma was expected, again pointing to a FET being open. To be sure of getting the right vintage of FETs, I ordered a couple of them (and thermal insulator) from Elecraft. My order was shipped that same day and arrived via priority mail 2 days later. Great service. Following the procedure described by others, I replaced both output MOSFETs. Since one had been inoperative, the other had been carrying the whole load to produce output so may have been overworked, overstressed and hurting. Here are my additional comments on the repair process: 1) The Elecraft document "KPA3CONMDKT MOD Kit Manual" has a wonderful description of how to remove and replace the 100W amplifier to allow access to the LPA's adjustment potentiometers. 2) Turning the power to zero is a good safeguard when doing the bias adjustment. I also made sure the radio was in USB or LSB so no power output would be commanded in any case. Now with the FETs replaced and the bottom cover back on, the moment of truth.. Three LPA potentiometers turned down. Turn first pot, +200ma. Turn second pot, another 200ma. Turn third pot, yet another 200ma. Success! Put the 100W amp module back in and connected to the Elecraft K3 utility. All 3 transmitter gain tests passed, and now the power setting is stable on all bands. On 40M where the reported SWR into a dummy load before the repair was 1.4 instead of 1.0 was now down to 1.2. Still do not know why but I can certainly live with that. So. why did this even happen in the first place? I can only speculate. Older generation MOSFETs were difficult to keep in their safe operating region without snubbers. Did some transient zap it? Power semiconductor chip bonding is subject to failure after a high number of thermal cycles, and this has been a contest radio. In January during the VHF contest, my 6M antennas became badly detuned with wet snow and ice accumulation. This led to a high swr propagating thru the transmit chain to the K3 which suffered a total loss of power output on 6M with a very high swr indicated. After a rest, the K3 recovered, but did that event set this failure in motion? GOK. And a closing suggestion- if your K3 is working OK now, save a copy of its configuration: this may turn out to be quite handy in the future.

Recently my K3 has experienced a couple of issues. I have been unable to get a response from Elecraft e-mail or telephone service regarding the situation. It's been almost two weeks now so thought I'd ask here if anyone has some suggestions for me to try myself. Here is the main concern: When getting ready for CQWWDX SSB a few weeks ago, I went through setting the transmit power on each band to drive an amplifier properly. The power display seemed a bit sluggish and had a delay in indicating the SWR. Worse yet, when I got to 40M, I could not crank the power up past about 30 watts; it would momentarily display a higher number but then fall back to 30w. All other bands cold be set higher. First I reloaded all the current firmware in the main and subreceiver. No change to 40M. So next I went to the K3 Utility ver 1.20.1.15 to do a transmitter gain calibration. Starting with the 5W calibration, it stepped thru the first few bands OK but then stopped (I think on 40M) and displayed "ERR TXG" and the message "calibration settled at 3.6W, TX gain failed because transmit power did not reach the expected value". In anticipation of having to send the radio to Elecraft where it might be totally reset, I manually started recording all the configuration settings. When I looked at my filter settings, I was shocked to see that filter 1 in the subreceiver was set to 1.35. Huh? It should have been 2.80 !! Was my config info corrupted? I reset that to 2.80 and then for the heck of it tried again to set the power on 40M. That now worked "OK" and the swr and pwr display during "tune" showed instantly on all bands. Something had changed. Next, I decided to rerun the TX calibration gain routine. This time if successfully completed the 5w and 50w routines. However, with a good dummy load, 40M displays an swr of 1.4, while the other bands are 1.0 or 1.1, so something is still a little funny on 40M. What might that be? I have now been considering doing a total reset of the radio using the EE INIT function and then the self calibrations. Is this wise? Any experiences or suggestions appreciated. 73, Chet, N8RA ______________________________________________________________ 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 chetsubaccount at snet.net From wes_n7ws at triconet.org Tue Nov 17 13:11:06 2020 From: wes_n7ws at triconet.org (Wes) Date: Tue, 17 Nov 2020 11:11:06 -0700 Subject: [Elecraft] KPA500+KAT500 interfacing.

I'm pretty sure the answer is "No". AUX cables don't do anything unless connected to an AUX compatible rig. It is, however, easy to feed the KAT500 with the rigs responses to KPA500 interrogations assuming the rig is Kenwood or Kenwood compatible. The KPA500 can be configured to poll for IF, FA, and FB. KAT500 is wired to listen to the FA responses. Email me for a cable sketch if you need it.

I do not consider the finger spacing ?bizarrely wide?. My Kent dual lever paddle which I used happily for decades, is spaced about the same. We all have our own preferences, so when I ordered my N3ZN paddle some years ago I did opt for a model with slightly less space. We all have our preferences, and if a parameter happens to be important, great, specify that. I have used dozens of paddles in my 66 year ham career, some with wide spaces, some narrow, some with magnetic return, some spring return and made peace with nearly all of them, even with my KX1 paddle which I still use occasionally for ultra portability. Personally if I was budget constrained I could easily enjoy my KX2 paddle or even the old Kent wide spaced paddle as my only paddle. I have even tested and used some of the foreign paddles in my shack which I am sure cost well over $500 and consider the KXPD2, even with its wide spaced finger pieces, a close second choice. Perhaps this is not relevant, but I enjoy very hot sauce on nearly everything. I do not consider mild hot sauce inferior, or expect others to choke down my sauce.

I believe the answer to the first question is yes. The KAT500 can follow the BDC band data. The answer to the second is definitely no. The KPA500 does not output (nor does it have the capability) BCD band data. The port has input, but does not have output drive. To go further, while the KPA can talk over the Auxbus, the KAT does not have capability to decode the data. In fact the only devices with the capability to decode KPA500 Auxbus data are the K3, K3S and K4. While both can follow Kenwood-format serial data, and both will respond to a short transmission burst, there is an advantage to having the KAT500 follow the transceivers receive frequency since it keeps the antenna properly matched for the received frequency. In order to do this you really need to have the KAT receive the transceiver frequency stream. As others have noted, it can listen to Kenwood FA responses (which the KPA can poll for). Several folks have created rather interesting boxes that can receive band data from transceivers and communicate it to the KPA500 and KAT500. You might want to talk with Andy, K3WYC about his rather interesting project. 73, Jack, W6FB > On Nov 17, 2020, at 8:27 PM, Wes wrote: > > The answer may be no, but you're not responding to the question asked. > > The KPA500 can be switched with Serial or BCD data, in addition to the Elecraft Aux Bus.

The KAT500 has a relay to interrupt the amp key line during ATU tuning, and the KAT500 can observe (but not change) the exciter-controlled band lines. The ATU needs the frequency. The amp needs the band. Both amp and ATU have TX freq counters. Both amp and ATU have publicly documented mechanisms to be controlled by external automation to return to freq-appropriate settings before transmission. We provide automation from K3, K3S, and K4 when you use the optional 15-pin ACC cables and select the appropriate settings in exciter, amp, and ATU. These are convenient, but not the only way the amp and ATU can be used. If the amp were able to set band lines for the ATU, it would be of marginal utility. The ATU could return to the last used setting on that band. As soon as you QSY, the ATU would probably need to move, based on the tx freq count. 73 de Dick, K6KR > On Nov 18, 2020, at 10:18, john at kk9a.com wrote: > > ?So what does the HD15 cable do from the KAT500 to the KPA500?

First, you are right, it passes the signals through from the radio. The second is that it can break the PTT line (in that pass-through) when the KAT needs to tune or otherwise change the relays while the system is transmitting (PTT being active). Note that both the KAT and the KPA use many of the signals on the AuxIO. These include the BAND lines, PTT, and importantly, the AuxBus line. The KPA500 talks on the Auxbus (but does not listen), while the KAT listens on the Auxbus. Because of the way the KPA encodes its data, the KAT cannot receive any data from the KPA, but only that coming from the transceiver. That is kind of an important point - there is no communications between the KPA500 and the KAT500, which eliminates the ability to do really close control between the two. 73!

Occasionally, the P3 doesn't display the TX waveform ( I have never noticed if this happening on SSB...probably not since I have never had to fix it). The fix is loading a config file stored when the problem was not happening. I have tried to store a config file when it was happening just to see and then restore using that file. What happens then is the P3 display locked up with a dit and could not be unlocked. After this test, I had to turn off the K3s and unpower the P3, restore power and turn the K3s on, and restore with a copy of the config which was taken when the display was showing transmit cw. I'm thinking stray RF somehow causing this but never happened on SSB...and I have no clue what is getting flipped in the rig or P3 to have this happen. Since I can restore the config and fix it, I guess I'm mostly curious why it's happening, any ideas?

This requires frequency, not band data. Tuning the K3 big knob results in a change of tuning solutions for antennas that require those solutions. After stopping tuning for a brief moment, one can hear the relays change. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From dave at nk7z.net Wed Nov 18 14:56:52 2020 From: dave at nk7z.net (Dave Cole) Date: Wed, 18 Nov 2020 11:56:52 -0800 Subject: [Elecraft] KAT500 question...

For that reason I didn't emphasize that KAT500 needs FREQUENCY not BAND. The cable for "KPA500 polls Kenwood and KPA500 and KAT500 listen to Kenwood" can be cobbled together for probably under $10 assuming you don't have the connectors and cable in the junk bin. You can also buy the cable from Elecraft. It works fine as long as you accept that KAT500 can only follow VFO A (limitation of current firmware). I was not satisfied with this (and other limitations) so I launched on a long, educational, rewarding, and sometimes frustrating, project to build a controller that made the Kenwood/KPA500/KAT500 interface work the way I though it should (I don't claim it works correctly , only that it works the way I want it to).

It has had the gold pin modification done to it and has worked well for years. I have calibrated the wattmeter and Tx Gain. Things track very well until about 90 watts. When requesting power above 90 watts, the K3 power sensor stays at 90 watts, and the actual output goes up to over 120 watts. I've attached a plot of the internal and external power indications vs. requested power. Here is a link to the plot (tested at 14.175 MHz): K3_SN00728_Power_Curve Other info (in anticipation of comments and questions): 1. External measurements were taken with an LP-100A wattmeter and corroborated with a calibrated scope and spectrum analyzer. 2. Transmitter was connected through the LP-100A sensor to a Bird 30dB attenuator, and additional 30 dB attenuator, and then terminated in a 50 ohm input on my spectrum analyzer. 3. The PA temperature varied from about 35C to 45C during the test. I started at the highest and lowest power settings and worked inward towards 50W which is why that temperature curve looks the way it does. 4. The problem is repeatable. I wouldn't squawk about this except that it appears that something is broken in the K3 power sensor. It tracks beautifully through the 5W and 50W calibration points, but then has issues at the higher power levels. Also, on some bands the power is so high that I get HI CURR warnings and power foldback. Any ideas? 73, be safe, have fun!

I set the CONFIG PTT-KEY parameter to RTS- DTR and the parameter does not change when I go in and out to the CONFIG menu, nor does it change when I change bands. If, however, I turn off the radio and then turn it back on, the CONFIG PTT-KEY defaults (?) back to OFF - OFF. I am using the KIOB interface and the RS232 parameter is set to USB with the resultant COMPORT is COM5. When this started recently when I was having problems with MITTY and N!MM with AFSK RTTY and I had to turn off and on the radio several times to change some cables. Normally, I very seldom turn off the radio - meaning for the most part, It's on 24/7. I have looked through Elecraft's and Fred's documentation and I could not find any reference to "Oh, by the way, if you do or don't do this, then weird things could happen". Has anyone else encountered this problem and if so, how did you solved it? Best regards, Jerry, W1Ie .

That would prevent the P3 receiving the TX and RX commands from the K3 so that the P3 gets hung up in TX or RX mode.? If you can lay your hands on a spare RS-232 cable, I would try it to see if that fixes the problem. If the RS-232 connection is confirmed OK and the problem still occurs, then: Have you tried cycling power without restoring the config file?? If it really does require the config file restoration to restore proper operation then it must be some setting that is accidentally getting changed.? That can sometimes be caused by some computer software sending commands to the P3 via RS-232.? Try running the K3/P3 with no RS-232 connection to the computer and see if you still see the problem. If the problem occurs with no connection between the K3/P3 and the computer and you can confirm that it does require a config restore to get back to normal operation, then it sounds like the EEPROM in the P3 must be going bad.? I have never heard of that happening, but I guess it's possible.

This is built into the KPA1500 which is a combination amp/tuner/antenna selector switch. The KPA1500 "speaks" Elecraft, Kenwood, Yaesu, and Icom. The KPA500 can use Icom "band data" voltages but that doesn't support the WARC bands. There is also no communication with the KAT500 to tell it what band/antenna to use. Yes, the KPA500/KAT500 combination switches perfectly to the proper band, frequency, and antenna on *transmit *but does nothing on receive. When just listening it is necessary to manually press the ANT(tenna) button on the KAT500 to select the proper antenna for the selected frequency (band) on the Icom radio. If you are trying to scan memories that doesn't work at all. Having the ability for the KAT500 to follow the receiver so it could select the proper band/antenna would be very helpful. Has anybody built such an interface or know of an existing commercial device that will perform the above function? 73, Ken WA2LBI On Wed, Nov 18, 2020 at 4:01 PM Andy Durbin wrote: > Some people seem to get quite hostile when I carefully distinguish between > "band data" and "frequency data".

Many years ago, a homebrew CI-V to RS232 interface was published in QST, and about 15 years ago, I bought two at a Chicago area hamfest that a ham had made a small business of building and selling.

R12 and R13 on the KRC2 PCB are properly labelled. R12, closest to the switches, is a 4.7K ohm resistor (yellow-violet-red) used to pull the RS232 line to -12V. R13 is next to it, closest to the DE9 connectors is a 47 ohm resistor (yellow-violet-black) and provides +12V power for the JFET. The legends on the PCB and in Figure 10 of the KRC2 Rev C manual are correct. Now, what caused you to think they were backwards? And, let?s make sure that you do have a Rev C board in your KRC2. 73, Jack, W6FB > On Nov 19, 2020, at 11:58 AM, Paul Fletcher via Elecraft wrote: > > FAO anyone who's had issues getting the serial comms working on a KRC2: > > R12 and R13 are transposed on the silkscreen on the PCB.

Message-ID: After a computer configuration change, I needed to figure out which COM port my K3 was coming up on. I ran K3 Utility and started trying COM ports. After several "Port Closed" responses, I tried another and the rig began sending *AA* and other stuff repeatedly. I couldn't stop it with the XMIT button, so I hit POWER to turn off the radio. Now, when I touch POWER the LCD lights up plain yellow as long as I hold POWER but as soon as I let go, the screen goes blank. I tried to begin the Forced Reload protocol by disconnecting power for 10 seconds, reconnecting, and HOLDing POWER for >10 seconds but, after at least 20 seconds, the MCU LD message still hadn't appeared. Any suggestions?

Usually throw in add ons put in later. Did that with my fully loaded second K3 7 years ago. And a KX2 I just sold to upgrade to a KX3. Buyers were happy and I was happy. If the good working radio is out of production I try to get 50% of what I paid. And try to get past eBay sales for the radio to back up that 50% ( or 75%) is a good value at a local fest. For vintage tube gear all bets are off and I try to get 50% of the last few eBay sales. 73, tom w7sua Arizona On 11/20/2020 7:42 AM, Jim Miller wrote: > I'm looking to buy a used KPA500 from a friend.

You know your own comfort level but to get your 2E0 license you had to build a circuit that worked and with that and given the Elecraft K2 build documentation is simply great, you might find the K2 build well within your grasp. On a side note, I think the UK licensing exams (I went through the whole suite about 18 months ago) enable hams in a way that we in the US should consider especially the entry level exam that requires candidates to get on the air and make a couple of contacts. I built mine back in 2010 and hadn?t really got a lot of kit building under my belt. I made mine and if you get stuck you will surely find a lot of people on this reflector to help you and I possibly the folks that helped you get through the 2E0 license build.

Upon first turn on, the xmit power could be set high on all bands as expected. But then, after a few hours of the radio just sitting there in receive, going to transmit it would not reach a power output past ~40 watts (varied by band and varies a few watts as it sits in transmit) and will fail the transmit gain calibration. Picking up on a possible related thread, I took off the bottom rear case panel and tested the two SWR bridge diodes. They both appear to be good according to my DVM. Is that a good enough test? My 12V supply voltage was a bit low according to other owners (13.4 v dropping to 12.9 v on XMIT)) so I adjusted the Astron SS-30M to 14.5 volts. Now, setting the xmit power higher works when going to TUNE, and the radio passed all the calibrate xmtr gain tests. So again I thought maybe that was it. But again, nope. After being on for over 8 hours in receive, and heating up internally, it fails to reach the set 70W output. But after being turned off for about 2 hours, it resumed producing the set 70W. See the attached chart. Looks like embedded pictures or charts are not accepted here, so this is the significant data I wanted to illustrate: 14 MHz USB Pwr set to 70 Watts At first turn on at 9 AM, the DISP readings were: V in rx 14.4 V V in tx 14.0 V I in rx 1.05 A I in ptt only 2.04 A I in full xmt 15.15 A PA temp 22C FP temp 16C At 4:05 PM when it failed, it had been sitting for 3 hours in receive-only: PA temp 35C FP temp 36C (97F!) Something temperature, voltage, time related? Any other ideas out there? 73, Chet, N8RA -----Original Message----- From: Chet S > Sent: Tuesday, November 17, 2020 9:22 AM To: 'elecraft at mailman.qth.net' >; 'Elecraft-K3 at groups.io' > Subject: RE: [Elecraft] my K3 has some issues-SOLVED- Low Power Amp MOSFETs Replacing the final output MOSFETs in my K3's low power amp appears to have fixed its transmit power issues. Thank you everyone on the K3 forums for your shared advice and experiences. The "3 screw" tests were pointing to a bad output transistor in the LPA. The idle current increase on the K3 meter when putting the radio into XMIT (not TUNE) was only 310 ma, where at least 600ma was expected, again pointing to a FET being open. To be sure of getting the right vintage of FETs, I ordered a couple of them (and thermal insulator) from Elecraft. My order was shipped that same day and arrived via priority mail 2 days later. Great service. Following the procedure described by others, I replaced both output MOSFETs. Since one had been inoperative, the other had been carrying the whole load to produce output so may have been overworked, overstressed and hurting. Here are my additional comments on the repair process: 1) The Elecraft document "KPA3CONMDKT MOD Kit Manual" has a wonderful description of how to remove and replace the 100W amplifier to allow access to the LPA's adjustment potentiometers. 2) Turning the power to zero is a good safeguard when doing the bias adjustment. I also made sure the radio was in USB or LSB so no power output would be commanded in any case. Now with the FETs replaced and the bottom cover back on, the moment of truth.. Three LPA potentiometers turned down. Turn first pot, +200ma. Turn second pot, another 200ma. Turn third pot, yet another 200ma. Success! Put the 100W amp module back in and connected to the Elecraft K3 utility. All 3 transmitter gain tests passed, and now the power setting is stable on all bands. On 40M where the reported SWR into a dummy load before the repair was 1.4 instead of 1.0 was now down to 1.2. Still do not know why but I can certainly live with that. So. why did this even happen in the first place? I can only speculate. Older generation MOSFETs were difficult to keep in their safe operating region without snubbers. Did some transient zap it? Power semiconductor chip bonding is subject to failure after a high number of thermal cycles, and this has been a contest radio. In January during the VHF contest, my 6M antennas became badly detuned with wet snow and ice accumulation. This led to a high swr propagating thru the transmit chain to the K3 which suffered a total loss of power output on 6M with a very high swr indicated. After a rest, the K3 recovered, but did that event set this failure in motion? GOK. And a closing suggestion- if your K3 is working OK now, save a copy of its configuration: this may turn out to be quite handy in the future.

Recently my K3 has experienced a couple of issues. I have been unable to get a response from Elecraft e-mail or telephone service regarding the situation. It's been almost two weeks now so thought I'd ask here if anyone has some suggestions for me to try myself. Here is the main concern: When getting ready for CQWWDX SSB a few weeks ago, I went through setting the transmit power on each band to drive an amplifier properly. The power display seemed a bit sluggish and had a delay in indicating the SWR. Worse yet, when I got to 40M, I could not crank the power up past about 30 watts; it would momentarily display a higher number but then fall back to 30w. All other bands cold be set higher. First I reloaded all the current firmware in the main and subreceiver. No change to 40M. So next I went to the K3 Utility ver 1.20.1.15 to do a transmitter gain calibration. Starting with the 5W calibration, it stepped thru the first few bands OK but then stopped (I think on 40M) and displayed "ERR TXG" and the message "calibration settled at 3.6W, TX gain failed because transmit power did not reach the expected value". In anticipation of having to send the radio to Elecraft where it might be totally reset, I manually started recording all the configuration settings. When I looked at my filter settings, I was shocked to see that filter 1 in the subreceiver was set to 1.35. Huh? It should have been 2.80 !! Was my config info corrupted? I reset that to 2.80 and then for the heck of it tried again to set the power on 40M. That now worked "OK" and the swr and pwr display during "tune" showed instantly on all bands. Something had changed. Next, I decided to rerun the TX calibration gain routine. This time if successfully completed the 5w and 50w routines. However, with a good dummy load, 40M displays an swr of 1.4, while the other bands are 1.0 or 1.1, so something is still a little funny on 40M. What might that be? I have now been considering doing a total reset of the radio using the EE INIT function and then the self calibrations. Is this wise? Any experiences or suggestions appreciated. 73, Chet, N8RA ______________________________________________________________ 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 chetsubaccount at snet.net From radio at disseminator.net Fri Nov 20 18:34:20 2020 From: radio at disseminator.net (Dave Erickson) Date: Fri, 20 Nov 2020 17:34:20 -0600 Subject: [Elecraft] ARRL Handbook 2021 In-Reply-To: References: Message-ID: On 11/20/2020 7:43 AM, Istv?n Szab? wrote: > Excuse me for the off topic, I got the ARRL Handbook without CD from FA.

Here is Elecraft's solution to my problem: " From your description of the issue, it sounds like you have USB.SAFE enabled for PTT-KEY. This is a feature to prevent accidental transmissions when a computer toggles DTR and RTS lines during a reboot. When USB.SAFE is enabled, it will keep PTT-KEY set to OFF-OFF until the radio receives valid serial commands over the serial connection. It can be confusing, since the setting will show as OFF-OFF until it receives those commands. You can toggle USB.SAFE off and on by tapping 1 on the keypad while viewing the PTT-KEY menu." This was from Rob in support. Chuck and Alan, as long as you don't tap the #1 key on the keypad while looking at the PTT-KEY parameter, this will not happen to you. Interestingly enough, the display will show UNSAFE and SAFE when in this condition and tapping the #! Will toggle the condition. I also think you have to have the KIOB module installed too. It sounds like it is USB specific and KIOA modules will not be affected (Ithink).

Unfortunately, there are too many rigs out there that produce them, even modern gear that should have been designed better.

I run my original Kenwood TS830 (I lurk here because I am thinking of purchasing an Elecraft, and wanted to see what folks have to say). I was surprised the first time I heard someone manually scanning the bands, and there were regular pops. They were at regular intervals, but I don't recall the freq step. It was on even boundaries, though, such as 3.900000 and so on. Not sure if it was on all bands, and I don't recall which rigs had it. Even so, it was more like clicks than pops, and not very loud. they would click in both directions as the boundary passed. I asked an op to "hold" on a click, but it was not possible.

There is also an edit box with up and down arrows to change L and C one step at a time. See if you can wiggle those to a place that better suits you. There is a save button once you?ve reached Nirvana. It may not be possible to get to 1:1.00 on every freq with fixed sized inductors and capacitors. Not all of the L and C are useful on any particular band. The largest are not used on 6 meters, the smallest don?t make much difference on 160 meters. You?ll hear this from others, but a minor mismatch isn?t going to make much difference at the other end of the QSO. But I, too, try to minimize this... 73 de Dick, K6KR > On Nov 20, 2020, at 17:58, Bob N3MNT wrote: > > ?I recently replaced/ upgraded the coax and balun on my Off center dipole and > no longer have to ability to get a 1:1 match using the tuner.

The ATU will do a second tune using smaller steps in inductance and capacitance values." All my Electraft ATUs have a similar feature. Downside - It does take much longer to achieve the match. 73 George AI4VZ On Sat, Nov 21, 2020 at 7:47 AM Dick Dievendorff wrote: > Bob: the KXPA100 Utility operate page should have check boxes for manual > selection of L and C.

References: <1134750320.108534.1605968389283.ref@mail.yahoo.com> Message-ID: <1134750320.108534.1605968389283@mail.yahoo.com> You sound exactly like me 20 years ago.? I built a K2 with all the options including the KPA100 but no KSB2.? They weren't all available yet when I built the K2 but as they became available they were all fun little add on projects, except the KPA100, which was a bigger fun add-on project.? Lots of toroids to wind, though bigger in the KPA100.? When I was building the K2 there was still some debugging and optimization of the design going on.? I was in the thick of it back then and have many many posts in the reflector archives. The K2 is the by far the best radio you will assemble yourself. 15-20 years ago it was still one of the best performing radios available. And, though things have moved on,? it still performs better than many current radios and is still one of my favorite radios to use.? I've been inactive on-and off since the early '00s but I've never run into a situation where its sensitivity or selectivity was limiting; DX pileups, contests, long ragchews, no problem. (still CW only and no KSB2). It's got a microprocessor of course, but all the signal processing and RF is analog, and done with the circuits you built; winding toroids, soldering all the discrete components, and aligning and troubleshooting it all in the end.? If it's not working great, there's probably something you need to figure out and fix.? If you study it as you go, you'll learn a heck of a lot about how radios work. Personally, I don't find SDR, DSP, digital modes and all the wizzbang associated features that interesting.? My favorite rigs include the K2, K1, Wilderness SST, and Rockmite with Miniboots amp.?? The K1 is a lot of fun and I used to use it as a nice compact rig to take along on business trips.? Too bad it's not available anymore. There's lots of room for different interests in ham radio.

It did receive a thorough alignment and 60m upgrade, courtesy of Don Wilhelm, approx. two years ago. It now excites an Ameritron AL-80BQ. I also own a Yaesu FT-991a (Purchased for its VHF/UHF SSB/CW capability.) While on paper, the newer rig's rcvr should handily outperform the older K2, it doesn't to my ears. The K2 is more pleasant to listen to and has, on at least one occasion, "heard" a DX sig that the Yaesu simply didn't using the very same antenna and comparable rcvr settings. I doubt anybody would be disappointed with the K2's performance, particularly on CW. Best of health and happy holidays to all.

As some of you may or may not know, I took over for Don Wilhelm, W3FPR when he retired in February of 2019. I am a third party service provider through my company W8FGU Services, LLC as well as an employee of Elecraft providing support and servicing of their Classic Line of products. Barry contacted me a few months ago to report the chirping (popping) problem and sent me his K2 for service. I spent a good amount of hours researching this problem where I was able to reproduce what Barry was hearing. It was through his wonderful description of how to produce the problem that I was able to reproduce the same issue on a number of K2's I have here in the shop including my own personal K2 #5099. With that said, I must emphasize that the great majority of K2 users will not be affected by this issue. There have been reports of chirps or pops during tuning in the past. Most were resolved by running CAL PLL again and making sure that the bottom cover was installed on the unit after plenty of warm up time. This is still the first line of defense when dealing with this problem. Unfortunately for Barry, this did not solve the issue he was hearing. And while I can explain why the issue occurs, I can't really explain why it is worse for some units than others except to say that the K2 was designed to use readily available through-hole parts with 5% and 10% tolerances and that it's possible those tolerances add up in certain circumstances. And, it must be remembered that the K2 is a 22 year old design. The fact that this design still produces a rig with the performance numbers it has after 22 years and is still available as a build-able kit is a great tribute to Wayne and Eric's vision and implementation. The issue: audio chirps and pops were being heard while tuning only when there were strong signals on the band within +/- 50KHz of the VFO frequency being tuned. These chirps were being heard every 5KHz of tuning. This happens to be the tuning boundary of the K2 PLL Oscillator. In a nutshell, at the 5KHz boundary, the PLL chip was programmed with new divide by registers and then the PLL Oscillator was moved to the min or max end of its range depending on the direction of tuning. Between these two operations was a brief period (a few milliseconds) where there was some instability while the closed loop of the PLL circuit settled down after the change in boundary. This produced a large voltage spike from the output of the PLL chip that caused the integrator circuit feeding the VCO varactors to sweep the VCO 50KHz or so in a few milliseconds. If there was a large signal in that frequency range, it was heard as a chirp or pop. It would be like spinning the VFO knob 50KHz in 8 milliseconds. This is why these chirps are not heard when there are no signals on the band in the area of tuning. As I was able to reproduce this issue, I believe in the past, I just simply blew off what I heard as atmospheric noise while I was tuning, especially on noisier bands like 40m. Barry could really hear it on 20m where there was less atmospheric noise but large signals on the band. This is especially exacerbated when tuning through the lower part of 20m during a contest where strong CW and digital mode signals made this very noticeable. Again, most users will not notice this especially if tuning slowly through the band. When using a tuning rate of 100Hz or 1KHz, it may be more noticeable as you are hitting the 5KHz PLL Osc boundary quicker. As I explained to Barry, I would never have noticed this before he explained how to produce it. Now that I know what it is, it drives me crazy. And I am not describing this to bring it to light for all of you (although I know many of you will try to reproduce it now - sorry). As Wayne explained to me, this type of PLL tuning design was fairly popular (and cutting edge) at the time and many radios of the time might produce similar results. What I came up with for Barry was a simple one-shot circuit that would punch the AGC line of the IF Amp during the 5KHz tuning boundary to dampen the volume for about 15ms to prevent the audio chirp. It monitors the chip select line of the PLL chip which happens when the process of setting the divide by registers is going to occur at the beginning of the PLL boundary reset. The pulse dampens the IF Amp long enough to allow completion of the boundary reset and prevent any strong signals to be heard that may be in the VCO sweep that follows. Again, the vast majority of users will not notice this issue, and as I mentioned, it may be at different intensities on a per unit basis. I am trying to develop a very small SMD version of this one-shot circuit for Barry to test out. This is not a documented mod as yet and has not been approved by Wayne and Eric in any manner except for experimental purposes. I just wanted to explain where things are at before this conversation became speculative or confrontational. I will be happy to answer any questions that may come up. 73, Dave W8FGU ------ Original Message ------ From: "Macy monkeys" To: elecraft at mailman.qth.net Sent: 11/21/2020 9:53:35 AM Subject: Re: [Elecraft] K2 purchase considered > >Me neither. #586. > >John K7FD > >> On Nov 20, 2020, at 10:13 PM, Vic Rosenthal wrote: >> >> Strange.

That could be a reason. Put in a plug with nothing connected and remeasure. Be careful with autoranging meters, they can fool you. Make certain you know what your meter displays for infinite resistance - it should be the same as shown with the probes apart and connected to nothing. Make certain you are measuring between the ring and shell of the plug. The tip is GPIO and its behavior is controlled in the KX3 menu. You should read an infinite resistance in receive and near zero ohms in transmit. Voltage measurements of an open drain FET do not have much meaning. Make certain your test plug is fully seated in the jack. 73, Don W3FPR On 11/21/2020 4:12 PM, Steve Zabarnick wrote: > I'm exploring using my KX3 with the QRP-Labs 50W Amplifier.

No need to drill holes: all the magic is in the cable connecting to the "AUX IO" connector. I added another transistor and a LED to verify working of the PTT cable. It all fits on a small piece of perfboard inside the housing of the connector. As to K2 vs other radios, I find I prefer the K2 to the K3 for sat work because the K3 has rather more birdies on 10m. But I do agree:important bit of the fun of the K2 is to build and modify it. 73, Geert Jan PE1HZG From k2asp at kanafi.org Sat Nov 21 17:08:17 2020 From: k2asp at kanafi.org (Phil Kane) Date: Sat, 21 Nov 2020 14:08:17 -0800 Subject: [Elecraft] K2 purchase considered In-Reply-To: References: <000001d6bf68$03442570$09cc7050$@gmail.com> <5FB87043.7040604@verizon.net> Message-ID: <66108ba0-f64e-1a91-ec6b-a43e4bc48489@kanafi.org> On 11/20/2020 7:16 PM, Jim Brown wrote: > No question, Robert.

A few days ago I came across a posting where someone said they were using their 'PLL VFO' aka their K2 as the substitute VFO (in absence of the xmtr having one) or as a crystal substitute. OK, how does he do that? Is he just running key-down at a low power of continuously keyed signal OR essentially keying the K2 at low power as a keyed-VFO into his vintage rig? Anyone want to venture a guess? I know I used to be able to use an old Hallicrafters tube VFO (Master Oscillator) as a continuous running VFO (irritating since the signal could be heard in the receiver if you did not turn off the final tube power when in receive) or it could be run as a keyed VFO, where the keying keyed the cathode of the final tube. So, similar kind of thing if attempted with K2? Anyone else done this? I have a few decent QRP rigs I could conceivably use as VFO / xtal sub / master oscillator ... whatever term to drive my older tube rigs (and avoid the mess of DDS....). Since I don't do 80m all that much, a 40m signal from a K2 or some other QRP rig would suffice to drive 40m, 20m and 15m as doubling and tripling of signal (IIRC). tnx Brian VE3VAW From bill at soundbusiness.us Sat Nov 21 18:19:24 2020 From: bill at soundbusiness.us (William Hein) Date: Sat, 21 Nov 2020 16:19:24 -0700 Subject: [Elecraft] K4D questions - diversity, HDMI, Ref In In-Reply-To: References: Message-ID: Hi, Wayne! I'm very happy about the phase sync between the two rxs, that will be a lot of fun! FYI - The Bodnar GPS unit outputs a programmable output including 10 MHz at various levels: Low-jitter GPS-locked precision frequency reference 450 Hz to 800 MHz output This device outputs two synchronised low-jitter reference clocks locked to GPS signal. Long term stability of output signal is defined by high accuracy of GPS Caesium references and theoretically approaches 1x10-12. Short term signal quality is defined by internal TCXO clock source providing high-quality, low phase noise clock signal with sub-picosecond RMS jitter. Digital PLL allows main output reference frequency to have almost any value between 450Hz and 800MHz. The second output frequency depends on the first output due to a common internal clock, if you need individual flexibility, multiple mini GPS units may be a better choice. If both outputs have the same frequency their relative phase shift can be adjusted. This can be used, for example, to generate two signals with 90? phase shift for use in I/Q mixer. Both output signals square wave at 3.3V CMOS levels with 50 Ohms characteristic impedance. Their output drive levels can be adjusted and outputs can be enabled and disabled independently. Output power level (measured at 10MHz, fundamental power channel): +13.3dBm, drive setting 32mA +12.7dBm, drive setting 24mA +11.4dBm, drive setting 16mA *Bill Hein* *Sound Business Strategies, LLC* *m 970-628-5120* *bill at soundbusiness.us * *The information contained in this transmission may contain privileged and confidential information, including patient information protected by federal and state privacy laws.

The KAT500 will accept either TTL or real RS-232 voltage levels. The KAT500 serial data transmitter is not RS-232 compliant (swings between zero and +12 V) and may not work with a true RS-232 receiver. It does drive a MAX 3232 with no problem. Whether the linked serial cable will work depends on the characteristics of the RS-232 port it is connected to. If that port needs true RS-232 voltage levels then it isn't going to work. (RS-232 swings positive and negative and is not zero referenced). 73.

I once had an experience during Field Day where my K3 was suddenly not transmitting or doing so at a very low level. Mine was traced to a SO239 connector that had worked loose and was not making good connection. You can also try recalibrating TX to see if that helps. In my case the unit went back to the factory for diagnosis, inspection and repair. Elecraft's gentle ministrations restored it to full function and I have not had a problem since. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of john at kk9a.com Sent: Monday, November 23, 2020 10:27 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] K3S MIC Problem I have not seen this occur, is there any chance that you were adjusting the VOX or some other way of accidently bumping that control?

Message-ID: I recently purchased a new KX2 with all the trimmings (AX1, AXE1, CW paddles, binding posts, etc.). Unfortunately, I?m hearing nothing but static. I had expected the KX2 to significantly exceed the receiving quality of my inexpensive SWL receivers. I am within 5 miles line of sight from some powerful AM stations. My Midland emergency radio has no problem in picking up the local AM stations - even the telescoping antenna fully retracted into the body of the radio. My KX2 cannot hear these stations. I cannot hear WWV on the KX2 (although my $20 clock radios can synchronize to it). I cannot hear any FT8 signals. Likewise, no CW. Granted, I am only using the Elecraft AX1 whip and not an outdoor antenna. But the AX1 whip is considerably larger than the telescoping antenna on my Midland even when extended. I?ve checked the RF GAIN (it?s at -0 db), the AF GAIN knob is turned up, and PRE is showing near the middle of the display. Maybe I am a complete idiot and am doing something wrong. Or perhaps my brand new KX2 was dead on arrival. Can anyone suggest next steps?

In-Reply-To: References: , Message-ID: I tried 80, 40, 20, 17, and 10 meter ham bands. I tried WWV on 5, 10, 15, and 20 MHz. I tried the common SWL frequencies. I tried mornings, afternoons and evenings. What is puzzling is that I am hearing nothing but static. It is as if there is no antenna. I tried a wire antenna in lieu of the whip. Still nothing. I?ve either got some software switch set wrong or there is a fault with the rig. FWIW - I was first licensed many years ago, built several analog radios from scratch, built Heathkits, and had contacts from all over the world. Although my knowledge is seriously dated I have a sense of what a good receiver can pick up. My old Drake 2B could usually hear many stations at any time of day. I did contact Elecraft. They gave me some initial suggestions. None worked. Waiting for a a reply from my email yesterday..

I operate various digital modes frequently (i.e.: FT8, JS8, Winlink, etc.) so I often return to the same frequency on each band. Today, running 50 watts in Winlink VARA HF mode, it had problems staying matched on 80 meters. It would try to rematch on each transmit cycle. As a result, the cycles were incomplete and data transfer was erratic. My question is, how many memory settings can it hold in memory, per band? My antenna is fed with ladder line (yes, I have a balun, etc and it's been fine for well over a year). It's possible that the system will tune slightly different now and then due to the ladderline blowing around (in contact with tree leaves, let's say). Am I using up so many memory slots after this time that it is running out of space? Thinking that might be a possibility, I reloaded a config from about 6 months back which would not have seen as many frequencies used. I have also experimented with the MTA commands. At this point, it seems stable. I've always been a bit confused by the "Teach it in Auto Mode, but Operate in Manual Mode" suggestion I've heard from time to time.

Then you put the tuner into manual mode; which still adjusts the matching values as the frequency changes BUT disables the retune feature.?

One thing I would do is check the tuner component values from your baseline (dry, sunny day) to the current values, it's possible that something is changing on the antenna more than usual (ladder/window line DOES change a little when wet or windy and near other 'things').? If the changes are small, you'll be fine.? Any major shift in values (or SWR) should be evaluated for cause (broken wire opens when windy?). I suggest that you limit the amount of feedline movement, if possible (I tied mine with a cord, to the fence, then it ran to the shack, slightly tensioned just enough to compensate for tree movement, not free sway).? That reduces the seasonal affects. You could also compare un-tuned SWR to see if there is a radical change, but SWR is not the entire story of the load (it's a composite measurement). Of course, make sure that your matching device (balun has variable meanings making that name, useless) has tight, clean weather resistant connections and isn't bothered by weather or seasonal debris (leaves). I came across similar changes when I used a 375' center fed dipole (80M EDZ) at only 35' (oaks didn't grow much taller), window line fed into a 4:1 common mode choke transformer and a SHORT piece of coax into the shack.? It worked well on all bands, I managed over 200 countries despite the local noises (noise floor ~-80 dBm).? Now I use a resonant antenna (80-6M plus one on 160M) which is MUCH simpler (but expensive) with a noise floor typically in the -120 dBm range (ah, quiet!?

Audio from both the CODEC and the Line In jack goes to a 74HC4053 switch on the KIO3B - only one "input" of that switch can be selected at a time. The control signal is a simple "ground" created when a plug is inserted into the Line In jack and applied directly to the 74HCT4053 without processing/control by the K3S controller. 73, ...

I try to pay attention to all those points, and really haven't seen this behavior until today. I still find the distinction between Auto and Manual modes a little fuzzy. Are you doing the "teaching" in Auto mode, but saying that operating should be in Manual mode ... like I think you're saying? Do you change the default setup, which has both boxes checked for QSY re-tuning? And then this: " Then you put the tuner into manual mode; which still adjusts the matching values as the frequency changes BUT disables the retune feature.

Right, the memory allocation - 6 solutions per bin - doesn't change but these 6 solutions could be for any of the 3 antenna ports. There is not a bin allocation for each antenna port. If you tune ANT 2 6 times and get 6 new solutions then any solutions you had stored for ANT 1 and ANT 3 are gone. There is currently no way to reserve any of the 6 memory locations for a specific antenna or to "lock" a solution that you don't want to be pushed off the stack.

Once the tuner knows the proper L/C combination for each frequency bin, it will switch to those settings in MAN mode. It will NOT try to autotune. If you switch to a different antenna on that particular antenna port, you will have to 'teach' the tuner again, which means going back into AUTO mode and transmitting in each bin's frequency so it learns what the L/C combinations are for each bin. Once that has been done, switch to MAN mode and operate. If you are using a remote antenna switch, things get complicated, but if you have only 3 antennas, it is easy. 73, Don W3FPR On 11/23/2020 5:34 PM, Lyn Norstad wrote: > Thanks, Rick.

As an example, I live in a stucco house, and with the wire on the walls before the stucco went on, I live in a faraday shield and few if any signals are received inside the house. That does include cellphone signals as well as ham frequencies. The AX1 does not work inside my house unless I take it near a window. So take a look at your situation - take the KX2 outside with the AX1 and a trailing counterpoise wire to see if you can hear any signals.

When you do a tune (Don's last step below), if the relays click for a long time before settling into a not-super-good solution, that is a symptom of no antenna, or a short circuit in place of an antenna.

In-Reply-To: References: Message-ID: <41478F6A-FA5A-4B8A-908F-A69FEA21D3CD@wunderwood.org> For the AM broadcast band, this is normal. Here is a 2016 post from Wayne, N6KR about using the KX2 for SWL. The reduced sensitivity is to reduce intermod in the PIN diodes used for T/R switching, if I remember correctly. Also, the KX3 and KX2 are designed to be used with the preamp for normal operation. ===== By the way, sensitivity of the KX2 is excellent for SWL segments between the ham bands. The sensitivity does fall off pretty rapidly below about 3 MHz because the KX2 was designed for 80-10 m and doesn't have filters specifically for 3 MHz or lower. You can still tune down to as low as 500 kHz, but you'll only be able to copy very strong signals below the 160 meter band. 73, Wayne N6KR On Jun 13, 2016, at 8:56 PM, "Wayne Burdick n6kr at elecraft.com [KX3]" > wrote: > Guy, > > The KX2 does very well with AM signals.

I understand why this is, and hope that it will change with the K4, but ultimately the K3, KX3, and KX2 are largely the same product that they have been for the last several years.

It should be obvious that technology has advanced by several orders of magnitude since then (remember Moore's Law?. That fundamental limitation is a major reason why features that are on lots of wish lists aren't implemented, and it's a major reason why there's a K4. Elecraft is a small company, so they can't afford to build new models as often as the bigger companies, but the K3 was a very innovative product that upped the ante for what a great radio should be. For example, it took ten years for Flex to incorporate the keying waveshaping that the K3 introduced in 2008, and, as far as I know, they're the only mfr to have done so (maybe ANAN?). All the other mfrs are using very primitive (and very clicky) simple RC time constants dating back 70 years! Elecraft also did some very slick stuff to make their phase noise much lower than most radios, again, back in that 2007 design. And they may be the only mfr to make their radios modular, so we can buy as much radio as we need, and so that some features can be upgraded by buying upgraded modules. If you want a new feature or performance improvement on a JA radio, you have to buy a new radio.It took Yaesu three generations of their then flagship FT1000-series rigs to fix their really awful clicks, and their current flagship, the FTDX5000 debuted with the worst clicks of any of its competitors. They didn't provide a firmware fix to make the clicks half as bad until I embarrassed them with my report summarizing ARRL Lab tests; by then the radio was 4-5 years old! 73, Jim K9YC On 11/23/2020 10:13 PM, Tim Tucker wrote: > But > one thing that the last few years has shown is that Elecraft does not have > a great track record of developing new features or technologies into their > existing transceiver products.

That said, we've provided literally hundreds of new K3/K3S/P3/KX2/KX3/PX3/KPA500/KPA1500 firmware revisions over the past 10 years, for both MCU and DSP code. Many of those releases stemmed directly from customer input. The K4 is a different beast entirely. It has essentially unlimited code space, and a high degree of modularity to facilitate future hardware. The team is still small, but we now have a much bigger playground :) 73, Wayne N6KR > Hello, all, > > I'm a brand new and generally satisfied Elecraft KX2 user. > > I'm just wondering what sorts of features are in the oven for future > versions of firmware. ....

Rick had some good ideas as well. It just dawned on me that part of my confusion came about as a result of using the KAT500 Utility from day 1. If I was just working from the front panel, the whole distinction between Automatic and Manual would have made more sense. But with the Utility and the separate Memorize button, that distinction is lost. At least for me. :) 73 Lyn, W0LEN -----Original Message----- From: Don Wilhelm [mailto:donwilh at embarqmail.com] Sent: Monday, November 23, 2020 5:24 PM To: Lyn at LNAINC.com; 'Rick Bates, NK7I'; elecraft at mailman.qth.net Subject: Re: [Elecraft] KAT500 Anomalies Lyn, I think you are 'getting caught up in the semantics' - let me try a brief explanation. Once the tuner knows the proper L/C combination for each frequency bin, it will switch to those settings in MAN mode. It will NOT try to autotune. If you switch to a different antenna on that particular antenna port, you will have to 'teach' the tuner again, which means going back into AUTO mode and transmitting in each bin's frequency so it learns what the L/C combinations are for each bin. Once that has been done, switch to MAN mode and operate. If you are using a remote antenna switch, things get complicated, but if you have only 3 antennas, it is easy. 73, Don W3FPR On 11/23/2020 5:34 PM, Lyn Norstad wrote: > Thanks, Rick.

I would take a different view, that MOST of the hams using Elecraft use MOST of the features on a regular basis but because the features are designed well, the user doesn't NEED to fiddle about (or understand the precise ways they work).? One of the benchmarks of a good UI is that most of it is set and forget.? Elecraft: PASS With the support group, the manual and the Cady book; there is ample opportunity to learn some of the nuts and bolts for those who want to know.? Once set to operate in the fashion that the user prefers; the radio (with all the features) is simply used.? If one doesn't understand a function or wishes to learn a better use of a feature, they can read or just ask (or watch a video if that is how they best learn). No one is born with all knowledge and I won't be disparaging to new hams; some of them blow right through all the exams in one sitting going from nothing to the highest license. They may not have experience yet, but clearly they're not idiots as you imply.? (Sadly, some are, even after decades of opportunity to learn better.)? It is the job of every ham, to teach them how to be better, to pass knowledge along. Some people LIKE making adjustments and learning the deep secrets of any device; others adjust according to their needs and a few just leave most of the settings as stock and yet none of them are wrong. Elecraft radios are no more complex than other radios but the simpler front panel UI (based on USING the radio, not fiddling with it) hides it a lot more than many other brands.? Then add that Elecraft designers actually USE the radios in all things ham radio; they understand what is needed for the 'average' ham, the DXer and the contester no matter what mode they choose. Kencomsu may, we never know and hear only crickets from them. The K4 won't be much different; simple up front with the bulk of the used (but no need to be in your face) features accessible with the menu UI.? Certainly it's a better platform for future growth with refinements unavailable when the earlier models were designed; but that's splitting hairs that only an extreme user (contesting, DXing) would require.? It will be a solid, dependable radio, no matter how the ham chooses to use it; with growth potential unavailable from almost any other brand. Name any other company that gives you FREE firmware updates in real time (not months later like Icom or never like most others) until the issues are resolved to the user satisfaction; or that ADD features previously unavailable. Or offer hardware updates or refinements, in part because the radios are designed to be modular and upgradeable as new devices are available.? Or board level support.? No, I won't disparage or belittle any of the Elecraft line; the UI makes it all available (mostly set and forget); you get to talk directly with the designers and owners of the company and they do more than any other company to make things 'right' in the eyes of the customer/user; not just give cookie cutter designs and answers then move on with no help provided. And the product line just works better, hearing ability is among the very elite and transmitters are cleaner on the air than most of the other brands. If a user is constantly fiddling about with the controls; it's because they either want to or don't understand their proper use and should ask questions.? Set and forget is an asset.? Once set, the complexity hidden within the UI is one of the strong points, because it doesn't require an EE and operation becomes simple allowing the user to simply use and enjoy the radio. If the user has not looked into all the settings, perhaps it's because they haven't needed to do so.? That's a telltale mark of a good product (although the ham SHOULD learn more about what tool/s they're using, in my opinion). Maybe you haven't dived into the depths, because you haven't needed to or other reasons; but I wouldn't group all users in that category.? Each user has an level of understanding and ability; no two are exactly the same; no two stations are precisely alike. When I first get any piece of gear, I go through every setting, making sure I understand it's use (adjust if needed); then I stop being concerned about the vast array of choices and just use the radio.? I may go back for refined adjustments, but that's not very often.? I suspect most hams are similar to that method.? If it's been a while, the manual, Cady book and group can be used (in that order) to find the proper control. By design, Elecraft radios can be used by a wide range of hams from basic noob to EE+ education; from ragchewers to ; they've hit the mark. They allow the hams to rise to higher level of understanding, competence and ability because of the quality; with some help from the manual, user groups, Cady book and DIRECT contact.? VERY few companies are at that level, other than Elecraft. 73, Rick NK7I "I can explain it to you, but I can't make you understand it."

Very few of us take full advantage of every bell and whistle, but newer radios do tend to enhance whatever experiences most amateurs seek. This applies not only to Elecraft but also to the other manufacturers. It would be commercial suicide for a company to produce separate radios for contesting, DXing, ragchewing, moonbounce, high-QRN environments, CW, SSB, RTTY, PSK, WARC bands, point-and-shoot, search-and-pounce, SO2V, diversity reception, pileup running, pileup busting, ... you name it. So almost all radios attempt to do well at most or all applications within various price constraints. Elecraft does distinguish itself with a small number of highly modular offerings and long-term support and enhancement commitments so you don't feel the urge to upgrade every three years. I enjoyed the K3 for about 14 years (and still do!), installing most but not all available upgrades, but the K4 is a new delight. There are features of K3 that I never used (e.g. external reference oscillator) and features of K4 that I may never use (e.g. multiple rx-only antennas) but others find them essential or at least highly desirable. Some will decide to buy a given radio based solely on some feature that others find extraneous. Yes, radio architectures change over time. Many are now digital, software-defined, direct conversion designs, quite different from the analog superhets that most of us grew up with. Their controls and features have changed. If their advantages don't outweigh (for you) the effort to learn a few new tricks (or concepts or practices), don't upgrade. For me, K4 represents the new generation of transceiver and I'm delighted with what it does for me. I feel like a kid in a new sandbox.

We did not have the Elecraft gear at that time, but what we had was not up to the performance/protection that is typical for Elecraft. Receivers have gotten much better in dynamic range and lowered MDS in general and Elecraft rates near the top of the heap. The AGC in the K2 and K1 (and K3/K3S) can handle the strong signals with no problem. It is not much different than reports of performance during a contest where there are strong signals and weaker signals. If we have a strong sunspot cycle, the weak signals will get stronger along with the more powerful stations. 73, Don W3FPR On 11/25/2020 6:52 PM, Douglas Hagerman via Elecraft wrote: > If, by some miracle, the sunspot count were to eventually jump up to a really high level, as was the case in around 2002, or even better in 1959, how would the various Elecraft receivers work?

I used a K1 with its simple SA612 front end during the peak activity for cycle 23 and 24. The problem that you have conjured is non-existent for practical proposes. There is nothing but joy to be had with any QRP rig in times of good solar activity. (I also used K1SWL's DSW-20, -30, -40 and MFJ Cubs for 40, 20, and 15 meters...all rigs with very simple front ends. I experienced no problems either.

However it remains that the Elecraft code is proprietary, just as most radio manufacturers code, name most any brand. Ditto car engine computer code (gas, diesel, hybrid or battery), computer program operating systems, networking products and more. It?s private and protected by laws. Try walking into Tesla and demanding copies of their designs and coding. You might just hope to land on the lawn, it depends on how well they toss you. While it?s possible to come close to duplicating the hardware (illegally), perhaps even take a good stab at the code; Elecraft gear still has their name on it, they stand behind it with both name and reputation on the line. So their code won?t be released to the public risking someone makIng poor changes, potentially causing issues, that could besmirch the name and product reputation that they?ve built up. That would be ruinous to the product, the users and financial suicide for Elecraft. Ditto Kenwood. Ditto Yaesu. Ditto Icom. And they?re not even in the same league as Elecraft. If the coder is THAT good, apply to join the team. Expand that team to anyone/everyone and you end up with radio version of Windows; bloated, slow, resource hogging that demands new hardware with each update or evolution and can?t get out of its own way to operate in mediocrity. If you want to roll your own, start at the very beginning, just as they did. No one stopped them, no one will stop you. I think they?re doing an excellent job and push their designs to the limit (K3); then take the next step with newer hardware (K4) to build on their success. You?re welcome to try and match all that; starting from scratch. Let?s not (ever) bring this up monthly anymore; the answer in the foreseeable future, is no. For excellent reasons.

He refused to do the key click mod (so he could grab and hold a frequency in a contest without people encroaching on it). He overloaded a Yaesu FT-897 which I replaced with an ICOM 706 MKII and overloaded that too. I ordered & built a K2 which took care of the overload, if not the key click problem. I loved that K2 and had a lot of nice successes with it. First off, I was working 160 meters one early morning, heard a Caribbean station (will remain nameless to keep from shaming him) calling CQ (not CQ JA or CQ DX) so I called him. He acknowledged but refused the contact because he said he was only working JA stations. I continued to listen to him call CQ for a while when a JA station answered him. After he returned the JA's call, the JA station said "Sorry, I'm only working USA stations this morning and then the JA called me! - Wow. I was only running the K2 at 5 watts on 160 and that was totally unexpected. Had a nice chat with the JA station (got the QSL card to prove it about a month later). Later, I inherited a tidy sum of money when my favorite Aunt passed away and got a full K line. Final to the story, the FCC got on the local ham with the key clicks so he had to fix them, I now had a KPA500/KAT500 behind the K3 and in a contest I could operate within a couple KHz of this guy with the K3's attenuator on and not have a problem copying/working weak signals. Back when he was overloading the Yaesu & ICOM rigs I had, I asked him to turn the amp off in local QSO's but his comment was "Get a real radio!". Well after I got the K line and ran the amp in contests, he asked ME to turn MY amp off. My response to that was -- "Like YOU said, get a real radio!". Shortly after that he moved out to a farm he inherited about 35 miles from me and I haven't heard him since - LOL. Speaks extremely well for the Elecraft line's strong (even extreme) signal handling capability. It was good, but not perfect with the K2 but even better with the K3 and now a K3S. At 78, I doubt I'll ever have a K4, but I fully expect the K3S to just keep on truckin' as it has for the last few years. Thanks Elecraft for some of the best rigs of the age.

Projects ranged from $1ooK to $10M USD. We had no warranty claims at all. It takes a lot to produce software and hardware to that level of reliability. Recently, someone posted on a different professional forum I am on "As a programmer I am faced with incompetence at every level. No one wants to put the time into making things great, just getting something out the door is the norm." I think that applies to a broad spectrum of products these days, and has applied for some time. A while back, I was participating in a cutting edge open source project. I commented on a design feature, supplying a schematic, simulation results, and references to various related technical specs. The reply from one of the "big" players was that he had not read those thousand pages of tech specs, but surely I was wrong. He even opined why, saying what he "thought" the tech specs must say. He got support from some of his pet squirrels. I dropped out of the project. This is not necessarily the norm...I'd like to think that it is a worst case. I know from personal experience that it takes a lot of time to understand a specific piece of hardware and its associated software. My company never went open source. I eventually closed it because I could not replace retiring professional staff from the current workforce. Not and keep the same level of quality. I don't have the Elecraft experience to speak knowledgeably about all these discussions, but I certainly understand the level of quality that I see, and understand the pressures of modern economics. I can't think of one open source, community-based product that I'd want to hang my hat on, even if I do see some that I'd support. I just don't see the professional depth in the general community. I'd actually vote in favor of opening the older Elecraft stuff up to community support, IF Elecraft went out of business or decided that some piece of gear is so old that it doesn't matter. (I actually own 2 pieces of gear that I'd love to see open source, but I don't see that happening.) Folks have invested a lot of $$ in their gear, and don't want to hear that 10 years later they need to toss it and buy new gear. ~R~ 72/73 de Rich NE1EE The Dusty Key On the banks of the Piscataqua On 2020-11-26 00:08:-0600, Tim Neu wrote: >The point on Moore's law is taken. > >But the options aren't just limited to Elecraft doing more work on older >radios or no updates at all (or supporting the old radios to the detriment >of the new) > >Many software development projects now are community based and although >radio firmware may be more time-consuming and more complex than OpenWRT for >example, community based development may have more umph than Elecraft might >have as far as inclination to tweak old radios. > >Just a thought.

Why are you bashing it on the Elecraft list? John KK9A Rick NK7I rick.nk7i at gmail.com And yet the TS-590 still has unfixed design flaws (overshoot being one of the worst) without sending it to an authorized shop, taking weeks. It was MONTHS before that firmware was updated (since originally reported). I find the reaction time for updates with Elecraft to be more responsive. Plus you can talk to a tech (except for COVID delays now) the same day you initiate contact. 73, Rick NK7I Scanned by McAfee and confirmed virus-free.

This is because a change of one in the line in on the radio gives you either 4 bars steady or 5 bars steady. Cutting down the levels from the computer will let you use more gain in the radio, getting to a place where the step size of the digital gain is smaller, giving finer control. 73 Bill AE6JV On 11/26/20 at 2:52 PM, jim at audiosystemsgroup.com (Jim Brown) wrote: >On 11/26/2020 1:43 AM, LDE wrote: >>Line In Gain = 40 seems too high to me. > >Numerical values are pretty much meaningless.

Once found (or so I thought) then there?s the task of compiling and loading the firmware after customizing specifically for one of 4 different mother boards the vendor shipped with the same printer model, using vague and incomplete recommendations from the ?community". Then there?s the matter of rounding up all the right libraries and versions used during the code ?make? when it fails. Oh and it may require re-flashing a boot loader as it is susceptible to corruption for reasons I cannot get a clear answer on. Once loaded to the printer, only then to discover it?s really worse than the version you hoped to repair, or dramatically changed in ways that demand relearning from the beginning. I would have gladly paid $$ extra for non-open firmware that was supported by the vendor and just worked!! I wanted to print - not test and debug code! There is real value in proprietary, closed source?. particularly if it reliably brings the features and functions I purchased and is well supported by a responsive vendor such as Elecraft.

I just don't see the professional depth in the general community." Presumably you're talking about the amature radio community because nonprofessional collaborative open source software development in general is alive and very well, but even so how about N1MM+, or even WSJT-X and derivatives?? I could probably come up with other examples if I was willing to waste more time on it.

Professional development costs money, and there's no revenue stream from free firmware for products that are not for sale. It might even have a negative effect by influencing users of older gear to keep it instead of upgrading. We are lucky that Elecraft fixes bugs in firmware for older products, and provides support for module upgrades. Some companies don't. There really isn't a simple solution, except to buy a K4 and make suggestions for new features while it is still the top of the line! Or, as I seem to be doing, follow Shimon Ben Zoma, who said, "Who is rich?

I wanted to print - not test and debug code! These are both situations I have experienced. I don't want to discourage independent dev. In fact, ham radio itself is a metaphor for this discussion, because have all sorts of user community dev, and some really creative ideas come out of that. But some of my thoughts apply to both areas. I do see in the ham community a rush to get products out the door, to get the next feature installed...at the sacrifice of explaining to the user body what those changes are, how well they were tested, and how to use them. Yep...the products themselves are a great help to the community. But most of the user community that I have directly interacted with has no idea how to dev a product, how to specify a requirement, how to specify a design, how to test the final product. Instead, users get to test and debug the results. I know from experience how much extra work is involved in doing the job correctly. I have heard community developers reply to criticism by saying how difficult it is to test every feature. I get it. Back in the 90s, I read an account in an engineering mag about upgrades to Cheyenne Mt. I'll gloss over the details. A company won the bid. The Feds agreed that it would take 4 years and 4$B to do the work. At the end of 4 years, the contractor came back and said that they were behind schedule, and it would take another 4 years and 4$B. The Feds said maybe, but not with you, and went out for bids again. They got a contractor who conducted business the way my company did. They came in ahead of budget and time. In the article, they specifically mentioned the processes that lead to their success. An engineer in one of our client companies showed me the article, noting that it was specifically about the business approach we insisted on. One of the engineers in that company asked me one day why we had so much paper, and did we /really/ need to discuss all that stuff. Couldn't we "just to it?'"? That same engineer changed his tune when we discovered a serious flaw in their design. (We were collab on a $10M project.) As a direct result of /our/ design and construction, that company became a market leader in a vertical market. So I encourage individual effort. I applaud it. I admire the creativity. But I'd like to have those creative individuals slow down, and perhaps collab with the right people to do a decent job, instead of foisting on the user base the responsibility of testing and debugging, and then "documenting", shotgun style, on fora and wikis. I'd like to think this comes across as a discussion point, not as whining. If engineers in large corporations don't follow this structure, it is not hard to imagine why community developers don't either. But this discussion is more about a social change over the past 40 years. I have a friend who works for a major car dealership. He said they have a constant stream of bugs that they fix, software and hardware. New car buyers are part of the "test and debug" community. ~R~ From TheDustyKey at imaginarian.org Fri Nov 27 08:24:57 2020 From: TheDustyKey at imaginarian.org (Rich NE1EE) Date: Fri, 27 Nov 2020 08:24:57 -0500 Subject: [Elecraft] Firmware development In-Reply-To: <23cac315-1995-f62b-d5f6-c635ae4d4025@gmail.com> References: <20201126143507.EAF26149AB6F@mail.qsl.net> <231C79C1-AC21-4CD3-A697-AA2B25362231@woh.rr.com> <23cac315-1995-f62b-d5f6-c635ae4d4025@gmail.com> Message-ID: On 2020-11-26 21:47:-0700, David Gilbert wrote: >"I can't think of one open source, community-based product that I'd want to hang my hat on, even if I do see some that I'd support.? ?

It's a matter of perspective. I don't use N1MM or WSJT-X, so can't comment. I have heard the same criticisms levied against these products, yet they are widely used. A product can be poorly developed (code, which most users don't get to see), and poorly documented (users learn from fora and talking with others), and still be widely used, because they are the best we have, not because they could be better. I do use other popular ham-related software, and I regularly report bugs to the developers, many of whom are friendly and easy to work with. We all bring different life experiences to the table, and those experience shape our expectations. I think that many of these discussions are necessary, though perhaps more useful elsewhere. "More useful elsewhere" doesn't mean useless here. We have reached a point were we are not comfortable putting criticisms on the table, but polite critiquing is a vital element of growth.

The server that carries this list is more than likely Linux based. Isn't the K4 linux based? Linux is open source last time I checked. I'm not seeing that closed source has a better track record, ie. Microsoft... How many commercial products are sold every year that become orphaned? Not being open source helped the consumer. 99% of consumers couldn't extend the life of a product five seconds either way. I too have run my own engineering business for decades, close to 30 years. During that time I've worked for both large and small companies doing R&D and production. If you are honest, open vs closed source has nothing to do with the quality of the product, either SW or HW. The quality is more of a commitment of the creators, experience helps build that, and commitment to good process. Elecraft didn't do this on their own, they depend on feedback from their users to keep a tight loop on quality. Sure, they could hire a massive Q&A team, but why when they have an experienced pool of users/testers who pay them to the QA. Wayne and Eric are clearly exceptional entrepreneurs who are in this for the long term. They care about their products and customers. Open vs closed is moot. It's simply a business call, and their call to make. My guess is that you may not even be aware of the open source influenced products you own. (Routers, tv's, etc..) That is a totally different argument whether Elecraft should open their source vs quality... I personally see quality and crap on both sides of the isle, and there is no monopoly involved...

According to the U.S. Bureau of Labor Statistics (BLS), this isn't necessarily true. Data from the BLS shows that approximately 20% of new businesses fail during the first two years of being open, 45% during the first five years, and 65% during the first 10 years. Only 25% of new businesses make it to 15 years or more. These statistics haven't changed much over time, and have been fairly consistent since the 1990s.1?

It seems that this thread has become the whipping boy for open source. I would suggest that it is irrelevant whether something is open or closed source. Much of the "stuff" we buy today is created and sold in a one off runs from China. Once produced it is sold at Walmart and few people care how long it works, as long as it's cheap. For the few who care most stores will do a "no questions asked" refund. And then the consumer is off to buy another piece of junk. Open source projects are often created by a single individual , or a few people, who care about creating a "thing". There is often no thought about money, profit, or even maintaining the project. There are a few that gain traction and in some cases change the world. I'm sure it's more than the few projects that we have all listed in this thread that thrive. It's no different than the stats above on business. Unless you can create something that is useful and compel people to buy and use, the product will eventually cease to evolve and the company will probably die. Many open source projects reach maturity when the goals of the project are meet. Those project are often abandoned... Not really that different from a business that no longer innovates. This seems like a silly debate to continue demonizing one method or another. Both methods are valid and are based of different motivations. And in reality they are indifferent to our opinions... I think the question originally raised was as to the possibility of open sourcing the older Elecraft code. My guess is that may not happen for a lot of reasons. As long as Elecraft is doing well in business why would they freely part with their intellectual property, I wouldn't. len From joseph.durnal at gmail.com Fri Nov 27 15:14:41 2020 From: joseph.durnal at gmail.com (Joseph M.

I would suggest that it is irrelevant whether something is open or closed source. There have been many good comments pro and con open source here...I am not sure how my comments came across...I am in favor of open source, and have produced open source material myself. My comments...and still my point of view...are more in line with the idea that stuff is rushed out the door. There is a cultural behaviour associated with this that is generally accepted, and is more in line with Len's comment re off shore manufacturing and big box distro, but is not limited to those. Rather, they describe an attitude and a behaviour that I disagree with. I was at a meeting a year ago where I chanced to discuss a proprietary $20k product with someone who was also using it. We both held the opinion that it was (is) an excellent example of extremely high tech delivered to market before its time. Another example that comes to mind is the DeLorme GPSR line. I have used them for years. When the line was bought by Garmin, I figured that I'd buy into the new company. After struggling for months, I returned the units to Garmin, and posted a lengthy review of the product. Their public reply was brief...that the product was not intended to replace the PN-60. Unfortunately, it didn't succeed at all, IMO. If you wanted primitive functionality and had no intention of using it at any sort of real (again, IMO) way, then it was a fine toy. At the time, all of the critical reviews of it were in line w mine. Positive reviews focused on superficial aspects. This is not a Garmin diatribe, nor is it current (they may have fixed all the deficencies_...it is simply an example of a company with deep pockets, in a mature field, rushing a product to market well before it was ready (perhaps 2 years). I just did a quick scan of reviews, and not much improvement. So the discussion for me is not open source v. proprietary...it is about the culture that has developed around much of the open-source AND proprietary markets. I don't think that we have addressed the issue completely here...rather a few different spot views. That includes my replies. I also don't think that we need to discuss it in depth here, because Elecraft is not open source, and many have made relevant comments already. I just don't want to leave the impression that I am opposed to open source...

One is whether or not open source software in general is quality stuff, and even "derivations" of open source software require that the underlying bits represent good design and good code.? Some here have essentially claimed that all open source software is undependable ... which I think can be proven to be a false impression. The other issue is whether or not Elecraft or any other company would want to open their source code, whether based upon open source elements or not.? Elecraft obviously would want to keep their software proprietary because we already expect that it has given them competitive advantages in some areas.? At least as importantly in my mind is the likelihood that opening up their software would make Elecraft vulnerable to customers who trashed their system with buggy third party versions of the software and then expect Elecraft to help them recover it, or to otherwise address the problem.? It's a no win situation for Elecraft, and ultimately for the rest of us. And by the way, some open source licenses require adapters to make any derivations they create to also be open source.? I believe the underlying license for WSJT-X to be like that. 73, Dave??

There is a lot of processing involved. I will read this before I respond. This is not the first time that I have disagreed with mainstream physicists on some subject. That's what makes the world go 'round ;-) But disagreeing is not the same as being correct, so it remains to wait it out and see. In particular, I have disagreed in the past based on the difference twixt micro- and macro-view of some system (such as the sun, or the solar wind-earth interaction). ~R~ 72/73 de Rich NE1EE The Dusty Key On the banks of the Piscataqua From donwilh at embarqmail.com Fri Nov 27 17:05:53 2020 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 27 Nov 2020 17:05:53 -0500 Subject: [Elecraft] K3 FT8 Levels Sanity Check In-Reply-To: References: <17525bf4-bca8-0e8e-d390-e99f32789274@audiosystemsgroup.com> Message-ID: <00771b40-2a4b-b1d2-4509-7635ac174cec@embarqmail.com> Jim, That may work OK for non-Elecraft gear, but with the power control mechanism used by Elecraft, not having sufficient audio drive will cause "power hunting". Drive the soundcard audio for digital modes to 4 bars solid with the 5th flashing on the ALC meter. Then set the power knob for the desired power. It is "in the manual". Failure to do so can cause the gain of the low level transmit stages to be increased which can cause distortion and overdriving of some intermittent stages. On voice modes set the mic gain for 5 to 7 bars with a normal speaking voice. Similar rules apply. Refer to the Setup for Digital Modes article on my website www.w3fpr.com for an expanded explanation. 73, Don W3FPR On 11/27/2020 4:33 PM, Jim Rhodes wrote: > Another thing to remember is that you are generating a signal in single > sideband mode.

What may not be obvious at a glance are the statistics and math that underlie the analysis. I may as well be in for a penny, in for a pound. I had thought before reading this paper that there is a good reason to think that the sunspot activity will approach 250, +- a really big window. This is only slightly higher than McIntosh's 233. I think that I disagree with his model, but agree with his math and his conclusions. I encourage anyone who has an interest here to read the various papers. They will not be casual reading. I have had many successes and failures over the years. One thing that seems to put me in a smaller class of physicists is that I don't mind being wrong. I am passionate and enthusiastic about my beliefs, and ready to change them immediately upon seeing proof that I am wrong. A while back I was pursuing a particular math approach to finding (mumble, mumble, space plasma physics), and one of the senior PhDs said that "some really f*** smart people" had developed another approach, and I'd better spend my time understanding what they did, rather than go off in a different direction. My math later replaced that alternate approach. You need not think that this implies that I am any brighter than any one here, but that it points to a closed mindedness that really surprises me in the scientific community. One of my friends is fond of saying that he thinks I am bright enough to have 2 brains...one the size of a BB, and other just a tiny thing ;-) I appreciate the humor. We can also be found in public venues declaring to one another (wink, wink) that we are so smart that our IQs are not just in the 90s, they are in the /high/ 90s ;-) I have seen many insights come from folks with the equivalent of HS diplomas, and don't place much stock on the "paper" I have filed somewhere. That's why it's not on my wall. At any rate, we will all hold our breaths. Even if Cycle 25 is a banner cycle, my rotating-spinning-toroid sun model may not be correct. I can live with that ;-) And the cycles are good cycles-bad cycles, because what might be good for hams will certainly be cause for concern for those operating satellites and orbiting people containers.

As for power ratings, yes, there are different power ratings, but the 15, 30 and 45 Amp versions all use the same plastic housing, which means they will connect with one another.??

It came together great, and works both on 60m as well as a base for a transverter. I thought that would have been the happy end of the story, except I?ve had some odd trouble with it installed. I saw this briefly the day after the SS CW contest, and on the second day of the SS Phone contest. In each case, removing the K60XV solved the problem and it did not recur. Here?s what I?ve observed. After leaving the K2/100 turned on for several hours, the rig is in receive mode, but the AGC is fully activated, with all ten bars showing on the S-meter. The receiver audio is entirely blanked. This condition is intermittent and random. It tends to last for several seconds to many minutes. It happens on all bands at the same time EXCEPT it does NOT happen on any TRN band that is configured (I have one configured for 50 MHz/28 MHz). This lead me to believe the K60XV was involved. During the SS Phone, I removed the K60XV and replaced it with a Re-work eliminator and K2/100 and the rig worked just fine for the next 10 hours. During the last three days, I opened the K2 up and laid the KPA100 on the workbench and left the K2 powered up with the K60XV installed. The problem manifested itself within hours. I was able to run a few diagnostics. The AGC activation happens in all all AGC modes, SLO, FAST and OFF. I was able to get a scope probe on the emitter of Q12 on the Control board. When the blanking occurs, I see a train of pulses around 2 mS apart - around 500 Hz. I tried poking a finger around various places on the K60XV board to try to exacerbate the problem. I wasn?t able to determine anything conclusive, although a couple of times I thought something in the vicinity of the K2 relay might be involved. I?m completely dumbfounded by this problem. There?s nothing in the K60XV that interconnects with the AGC system in any way. What could possibly be going on here?

When this fault condition occurs, what is the voltage on K60XV P1 pin 6. If VRFDET becomes active during receive, the K2 may behave as you describe because the firmware 'thinks' the K2 is transmitting. The fact that you do not see it on the transverter bands further amplifies my thoughts on the source of the problem being the VRFDET signal. I cannot think of a component problem that would create your condition, so that is why I asked you to review the soldering.

That might imply that something is breaking into oscillation and overwhelming the VRFDET line.? That is why I suggested you check the component placement and the diode orientation. That intermittent condition can also be caused by a soldering problem that takes some time to appear. For the non-transverter bands, it is only necessary that the 4.7pF capacitor be in the circuit and that relay K1 be in the reset position. If you hear a relay click when this problem starts, then look to the firmware on the K60XV to make sure all its related components are in place - there are not many.? If you do hear the relay click, one thing you can do is to arbitrarily replace the resonator.? While I have never seen an intermittent resonator (dead one = yes), it is one possibility. 73, Don W3FPR On 11/28/2020 5:59 PM, Bill Coleman wrote: > Thanks, Don, I?ll check it out when I have a chance next week.

Power Pole connectors come in MANY sizes -- different housings, different inserts. The 15A and 30A inserts are pretty easy to install if you buy the inserts the fit the wire. The 30A inserts are good up to #12. The 45A inserts are needed for #10, and they are VERY tricky to install. I've installed many hundreds of Power Poles, all soldered. The caution about where to buy them is very good advice. BTW -- the red/black zip cord is NOT ideal for use around RF.

Works fine albeit shortens the cable a bit. Sounds good, Phil. If you care to start from scratch, an even better solution is to buy two colors of stranded THHN at the big box store, cut equal long lengths of both cables, tie one end to something like a vise attached to a bench, the other to a drill, with the cables stretched out flat, and run the drill slowly until you've passed the degree of twist that you want (more is better). Then set the drill down for a day or so to let the cable "remember" its twist. When the cable is removed from the drill, it will untwist a bit, and the twisting will not be uniform from one end to the other, but it's good enough. 73, Jim K9YC From kevinr at coho.net Sun Nov 29 23:45:13 2020 From: kevinr at coho.net (kevinr) Date: Sun, 29 Nov 2020 20:45:13 -0800 Subject: [Elecraft] Elecraft CW Net Report Message-ID: <09b7dc28-c891-0f57-7589-8918a40a830d@coho.net> Good Evening, ??

When I ?run? I get fan starting running after 10-15 minutes. However after another few minutes of running the fan will shuts down every time I press a key ( I am CW op). As a result the temperature of the PA goes higher and higher and at certain point the PA shuts down. If I check the temperature reading through temperature calibration in the menu I see that temperature reading jumping force and back with range of readings 10 - 20C. That kind of erratic temp reading continues even when temperature of the heatsink goes down. If let the trcv to cool (overnight) the temperature readings are stable with range of reading +- 1C. I check soldering and mounting - if there were problem they were fixed. But no results so far. I also upgraded the PA a week ago and that did not have effect on the overheating. Any input will be appreciated. 73, Arkady From jim at audiosystemsgroup.com Mon Nov 30 17:11:10 2020 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 30 Nov 2020 14:11:10 -0800 Subject: [Elecraft] K2 KPA100 overheating/erratic fan problem In-Reply-To: <69abe7a3-11f8-4294-b60b-1fab1743b473@Spark> References: <54bdcb65-d268-4c7c-9ec6-dcef1da56d53@Spark> <69abe7a3-11f8-4294-b60b-1fab1743b473@Spark> Message-ID: On 11/30/2020 2:00 PM, Arkady via Elecraft wrote: > When I ?run?

This is after all the A to B changes, including specifically the PLL temperature compensation upgrade, which includes the new crystal X1 and the thermistor board replacing the resistor pack. The counter works fine, tested on the BFO. The reading on TP3 is around 125, jumping up and down, not anything like 12085. When I tap BAND+ and BAND- the reading goes up and down as expected. I have checked carefully for short circuits. What should I look at next? Thanks. Doug, W0UHU.

Went back to original 10 uH for L31 and it?s fine now. Doug, W0UHU.
