All of these functions implementing this logic are not date specific functions.??'Copy' is just copying the year out of the string representation of the date.'StrToIntDef' is just converting those 4 characters to an integer (or -1 if the conversion fails).'Between' is just returning 'True' if the integer falls between 1950 and 2020 I think 2020 was just arbitrarily picked as a year.? These kind of arbitrary decisions are usually limited to code using 2 digit years.In the day it wasn't uncommon to see logic that turned a two digit year to a 19xx date if the year was greater than something like 30 and 20xx if it was less than 30 or so. Like many programs, this one has obviously outlived its expected longevity.

In-Reply-To: References: Message-ID: <01c401d786f2$00b97240$022c56c0$@LNAINC.com> I'll chime in too, echoing what Ken says. All you need is the "tune" cable to connect the KAT500 to the rig for control of the Tune function. I also use the LDG cable (just because it's easy ...) but you can easily make your own. (I am not familiar with the Ten-a-Tuner mentioned by Buck ... perhaps it is the same?) I prefer to use the Elecraft Utilities for both KPA and KAT500 for all tuning and setup settings, but the Tune button on the rig (or tuner) works fine as well (it automatically supplies the proper power for tuning). Generally, for digital operation I set the rig to about 18% power. For SSB, up to 25%. All the rig settings are automatically stored with each saved config file. The only downside to using Icom gear with the KPA/KAT500 is that Elecraft does not "read" the frequency "voltage" indicator and therefore does not preset the tuner to the correct values without transmitting. That ultimately is not a big deal, but does produce a 2 or 3 second delay for tuning when first transmitting after a band or significant frequency change. I generally hit the utility's Tune button as soon as I change so the receiver sees a good match. 73 Lyn, W0LEN -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ken Winterling Sent: Friday, July 30, 2021 12:41 PM To: Buck Cc: Elecraft Reflector Subject: Re: [Elecraft] KAT500/KPA500 with IC-7610? Chuck, I, too, have been using an IC-7610 with the KAT500/KPA500 combination for several years. My IC-7610 TUNER jack is connected to the TUNE jack on the rear of the KAT500 via a LDG Electronics IC-PAC-6 cable. While the TUNE button on the IC-7610 or the TUNE button on the KAT500 activates the IC-7610 10W tune function and causes the KAT500 to tune, the Elecraft KAT500 manual stated "If a tune cycle is performed, 20 watts or more will produce more accurate tuning". My procedure is to switch to RTTY mode on the IC-7610 and key the rig. The KAT500 matches the load and I return the rig to the previous mode. This literally takes only a few seconds. Yes, the TUNE button works but I have found that sometimes my method produces a better match. Be sure to follow the KAT500 "training" procedure to store your various bands and frequencies in the tuner so they can be quickly recalled. As has been mentioned, you have to manually adjust your output as you switch between the amp and full power. I have a Brother P-Touch label on the amp to remind me about max power input. As for obtaining a tuner cable, you can get one from LDG, and other vendors. The IC-PAC-6 cable is 6' long while the IC-PAC cable is 14" long. https://ldgelectronics.com/index.php/products/accessories/cables/ GL & 73!

May work for you but are you using KAT500 antenna port selection? My issues with RF detection as the primary tuning mechanism include the fact that the KAT500 will fault before it has time to select the correct antenna for the band in use. I need the KAT500 and KPA500 to be configured before I transmit. I suspect that anyone who uses KAT500 antenna port selection would too. 73, Andy, k3wyc From d.cutter at ntlworld.com Sun Aug 1 16:31:43 2021 From: d.cutter at ntlworld.com (CUTTER DAVID) Date: Sun, 1 Aug 2021 21:31:43 +0100 (BST) Subject: [Elecraft] KAT500/KPA500 with IC-7610?

My "nit" to pick is that the KAT500, as has been said, can not be preset by the IC-7610 in receive. It can preset the KPA500, for all bands but WARC, by using a DIY "band data" voltage cable (Icom doesn't support band data voltages for the WARC bands). If I want to *listen* to different frequencies on the IC-7610 that are on different antennas connected to the KAT500 I have to manually select the antenna on the KAT500. This makes scanning frequencies on the IC-7610 impossible. The KPA1500, that combines an amp and antenna matcher (aka tuner), can read Icom CI-V data and preset both the amp and the "tuner". This feature should have been/should be available for the KPA500 and KAT500. I believe the KPA500 and KAT500 can read data from Kenwood and Yaesu transceivers. Why was Icom left out of the mix?

Message-ID: Good Evening I bought a used KXPA 100 with tuner that had been stored and It seems to have a difference between the power setting on the KX3 and the actual output power. When I set the Kx3 for 50 watts I get about 40 watts out into a dummy load. It?s the same when set for 100 watts, I get about 80 watts. I first noticed the difference because of the low reading on the KXPA 100 power display, so I connected the to a watt meter with a dummy load. I have ran the the calibration routine two times, and the power output is a little closer to the set power, but still lower. It is similar on all bands, not just one. I thought I was low on Voltage so I shortened the power cable to about 2 feet and verified that it?s holding up during the key up test with a fluke meter. I am also watching the amp with the computer interface program, and the input voltage is staying up in the 12.6 range or so. The amp and the KX3 both have up to date firmware. The SWR is running about 1.1 to 1.2 into my dummy load. If I crank the power to 110 watts, I get about 95 watts. I don?t see any high current conditions and nothing appears to be getting hot.

Why? All the owners of K4's, (and any later rigs), would start to apply that to the "Do I need to purchase a $5K radio, that will not be supported, after a new model comes out", thought process... Hams have long memories... Elecraft is aware of this. Elecraft was kind enough to let everyone know, and build an ordering process for one last set of addons for the K3/3s... I have not seen Icom, or any other maker do that for any radio... I may have missed it, but I am happy that Elecraft did that, and not worried... As long as parts are available, I am sure Elecraft will do their best to repair K3, and K3s rigs... 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst.

I had not been paying attention to the fires in British Columbia. The wind shifted a few days ago, now coming from the southeast.

Also included are the P3Y Cable for connection to K3 System, P3IOBNC cable for connection to K3/K3s IF output, DC power cable for connection to K3/K3s Auxiliary DC output for power, original manuals. We are downsizing our home I need the room for the new smaller station desk. $1,200 if purchased new if available. currently "unobtanium" from Elecraft: There were rumors Pre-COVID and California Wildfire/Flooding that another, final batch of P3's were to be built, but there is no confirmation that this will happen; this may be your last chance for a clean, like new P3 for your K-Line station. The P3 and P3TXMON are only sold as an integrated unit, will not sell each independently of the other. Uninstalled and available for shipping August 3, 2021. Asking $950 shipped via UPS to the lower 48 upon receipt of PayPal funds. Due to "parts swapping", all sales are final.

The encoders in my summer 2008 vintage K3 degraded to the point where they often count backwards, making adjustment of CW speed or power out difficult. I've purchased four replacements from Elecraft and have been working up my courage and taking deep breaths. Getting to the board is a fairly complicated first phase. I had an Elecraft document on installation of an audio LPF on the DSP board and found it to be very useful in this process. Of course the original assembly manual is also useful. Now I've got the K3 apart to the point of allowing access. The upper two encoders have terminals located beneath an LED mounting board and are almost impossible to access from the top. I may stop after replacing the lower two, assuming I'm successful with them. My usual method involves solder wick plus flux. Sometimes I find ChipQuik to be very helpful in allowing me to remove a part without getting rid of all the solder. In this case though, using ChipQuik would require heating seven joints simultaneously which I haven't been able to do. There's also an issue with mounting the encoder at the correct height so the shaft switch can be operated. So I'll try to match the height of the new shaft end to that of the existing encoders. I found one website which is somewhat helpful discussing this task: https://www.n5na.net/s9y/index.php?/archives/26-Replacing-Elecraft-K3-Push-Button-Encoders.html I'm keeping a lot of notes.

I think what he meant was that the electrician could not legally wire a 120V duplex receptacle for 240V. And he is correct about that -- no 240V to a 120V receptacle. But from what I learned online, an electrician COULD install a special 120V receptacle that is rated for 30 amps (regular household receptacles are rated for 20A), and wire that 120V circuit from a 30A breaker with #10 wire. That would be a single run to a single receptacle, and would carry 120V, not 240V. So if you want to run a KPA1500 from 120V, tell the electrician the current draw at 120V, and ask him about running a 30A 120V circuit to a 30A receptacle. 73, Mike N4CF From mike at mdodd.com Thu Aug 5 14:05:18 2021 From: mike at mdodd.com (Mike Dodd) Date: Thu, 5 Aug 2021 14:05:18 -0400 Subject: [Elecraft] Plug on KPA-1500 In-Reply-To: <610C1D62.3060000@mdodd.com> References: <00F2B91A-F645-44BA-A6DC-D545EE2B7DE7@gmail.com> <1127559200.2008554.1628181994417@mail.yahoo.com> <610C1D62.3060000@mdodd.com> Message-ID: <610C285E.40606@mdodd.com> On 8/5/2021 1:18 PM, Mike Dodd wrote: > So if you want to run a KPA1500 from 120V, tell the electrician the > current draw at 120V, and ask him about running a 30A 120V circuit to a > 30A receptacle.

I assume you are in the USA. My KPA-1500 came with a 6-20P 240V plug like here: https://shop.worldcordsets.com/shop/categories/NEMA-620P-Power-Cords . Your picture did not come through, so if your plug is different, I would contact Elecraft. I was not aware that Elecraft has ever meant the amplifier to be operated on 120V, at least from what the specs say. Elecraft would know if your amp was wired for 120V. If your plug is similar to the ones on the link, I'm concerned why the electrician would have said that it was a 120V cord. The 6-20P is definitely a 240V (USA) plug. If all else fails, ask him to install a 240V 6-20P outlet for you. Again, do contact Elecraft if your plug is different from the link above.

Now, one has to be realistic in expectations. To have replacement cards made for replacements or upgrades, manufactured in small numbers will become prohibitively expensive. Elecraft does not manufacture their own boards. Once their stock is depleted, cards obviously will be come unavailable. Wayne has stated in this forum that his repairs will go to component level, when cards are gone from stock. So now component availability will be the driving issue. I believe the K3/K3S has been in production for over 15 years and I am sure they have dealt with component obsolescence in the past, but know we cannot expect an engineering team to do redesign work for an out of production radio. Replacement processor's, memory, ADCs, etc, could be a problem as component obsolesce kicks in. I too have a K3, that I want to move from my home station to support my portable work and replace it with a K4 (When the kit version comes out). In my opinion based on Elecraft's past performance and statements made by Wayne and Eric, loss of maintenance support for the K3/K3S will be due to parts obsolesce and not Elecraft lack of support. I too look for years of usage out of my K3. 73, Charlie, N2PKW -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Thomas Donohue Sent: Monday, August 02, 2021 8:26 AM To: Elecraft at mailman.qth.net Subject: [Elecraft] K3/K3S Options and Upgrades [You don't often get email from tomdon92 at gmail.com.

It came in at noon today. Took me a while to fabricate a power cord. With inline 20A fuse, natch. The Bird says it makes over 100W. It also has the audio filter, which my K2/10 doesn't. And the ATU. Buying the K2 seemed to be the only way to get a KPA100. Sometime next week, I'll take the new K2 apart and see if it has the mods. I have put aside my Tiny Linear project for the moment, in favor of the Alpha 78... Even though the Tiny Linear got me an S9 report from *Barcelona* on 20M SSB this morning. 800W just seems like more than 65W :). The only trouble with the Alpha is that LOUD blower. I do have a new blower for it - got it back when Alpha still stocked such things - but am not sure how much quieter a new one would be. A pair of noise cancelling headphones fixes it right up though.

The radio looks "Like New" even though it's an older unit: Serial 822.? Perhaps the radio has the front panel "tin pin" problem?? I'd appreciate you reviewing the following symptoms and let me know if you have any suggestions.?Things that work: POWER button turns the radio on/off and the front panel Display lights and displays multiple items including Frequency. AF control turns the volume up/down.? VFO A and VFO B knobs change frequency. Receives signals well, S-meter works fine, and CW stations have a nice clear tone.?Things that don't work: the BAND, MENU, DISP as pressing these have no action.? However, pressing some front panel buttons cause the wrong function, such as: pressing the XMIT button turns the PRE on/off and holding down the XMIT button turns on the ATT.? Similarly, pressing the ATU button on/off switches the AGC from Fast/Slow.?I once had a K3 get sick after being shipped cross country and the solution was to Reset the radio through the recommended Initialization process.? However, I haven't been able to do an Initialization of this K3/10 because "pressing and holding down the SHIFT/LO button while pressing the POWER button" as the Manual instructs doesn't Initialize the radio as it should.? ?Thanks in advance for your recommendations.? Write direct if you wish: RLVZ at aol.com? 73, Dick- K9OM? ??

Every one puffed after some months despite being properly balance charged, not overdischarged, and not really used very hard. They continued to operate, but they were clearly outgassing. I've had many, many Hobbyking Lithium Ion packs without this problem, only the LiFePO4 seemed to suffer in this way. That was a few years ago, so perhaps it's not the same now. As was noted there's no BMS which means a balancing charger is needed, and extreme care to not overdischarge them. A small per-cell meter would be important to monitor the cell voltages periodically. Many folks report good results from the Dakota and Miady LiFePO4 batteries, as well as the Bioenno of course. Miady overstates their capacity and current ratings, so more reasonable data should be used. I've just graphed a Miady 8AH discharge (Amazon $35), and it puts out a solid 7 amp hours rather than the rated 8. Right now I'm graphing a Bioenno 6AH that's less than 2 years old and it just stopped at under 4.6 amp hours out of it's rated 6 (testing at 10 hour rate). You don't really want to run them fully out anyway, so expect about 80% of the rated amp hours and value accordingly. I also ordered some Bioenno in May for Field Day and am still waiting, so apparently they are having supply problems like many others. The Miady came a bit out of balance, letting them sit on the charger for a day or two will allow the BMS board to balance them which increases useable capacity. Clearly when selling a LifePO4 battery at these low prices they can't spend too much time on them, so the final QC is left to the buyer. It's easy to return Amazon items so charge them and check their voltage and amp-hour capacity, or buy more expensive brands that do more testing for you. The two Miady batteries I've tested seem to have 85% of their rated capacity out of the box, but their cost is about 35-40% of the brand names. Even the brand names don't always reach label capacity. I use Bioenno for the high current loads but for lower current items perhaps the lower cost battery is a good budget choice. Test it during the return period and see if you agree. There are quite a few Miady (and other) reviews on utoob, most who actually use them for awhile have had decent results. 73 de w6akb On Sat, Nov 16, 2013 at 9:57 AM Esquer Dave wrote: > Hello Arno, > > I just picked up 2 of these 13.2v, 4200mAh LiFePo batteries from > HobbyKing.

I know both tell you how to remove the Front Panel assembly. That will tell not only how to remove the assembly, but just removing and re-instaling the Front Panel may wipe the pins enough to remove any oxidation and restore proper operation. If tin pins, ask support at elecraft for the gold front panel pins. The old tin pins are not difficult to remove if you work on one pin at a time - remove the plastic separator, cutting it if you have to, then remove the pins one at a time.? Clean up with solder wick, and if solder remains in the holes, heat the solder pad and push it out with a wooden toothpick. 73, Don W3FPR On 8/7/2021 1:48 AM, RVZ via Elecraft wrote: > Hi Guys, > > I received a used K3/10 this week via UPS Ground and it arrived sick.?

If below SN 3000, it likely does not have the alternate AF gain wiring. In any case, with those symptoms, replace tha AF Gain pot. Check to see if the KPA100 has the latest updates.? The instructions for the KPA100UPPKT will tell you. Also check for the latest KPA100 shield.? The latest shield has spring clips to ground it to the base K2 (sand the paint off the contact places) -- also check for the width of the slot above the SO239 jack, it should be narrow (a bit over 1/8 inch).? If it is the older wide slot, replace the shield with the KPA100SHLDKT. You can use the K2ATOBKIT instructions to check for other upgrades - be sure to check all the mod kits that are listed on the 1st page of the ATOB instructions.? Also check the markings on the crystals both on the RF Board and the KSB2 adapter - if they are maked with a "-S" suffix, they are the latest. You can check the firmware level for the base K2 easily - hold any button down while powering on and the MCU and KIO2 levels will be briefly shown in the display - the latest is 2.04r MCU and 1.09 KIO2. If you do not remember how to disassemble the K2 to get to the headphone jack, take a look at https://www.qsl.net/wy3a/Replace_K2_Headphone_Jack.htm. 73, Don W3FPR On 8/7/2021 2:05 PM, jerry wrote: > All, > > ??

It's job is to remove heat from within the K2 chassis rather than cool the actual PS transistors. Now to rake over old coals. A few years ago I was providing a signal source, QRSS 30 seconds dot period for a mutual grey line propagation investigation between the Falklands and the UK/EU. The fan became a problem because I left the K2 keying overnight at 20W and the shack is adjacent to the bedroom. The lady of the house was unimpressed. To overcome this I purchased a 80mm square 12V computer fan and experimented with location and orientation to determine the best solution. This is where there is a divergence of opinion. I found that by propping up one side of the fan on a simple square wire loop so that it was 45 degrees inclined to the heat sink and blowing down on it at the location of the PA's I could run the K2 at 30W output overnight and the fan never activated, the heat sink remained cool and was acceptably quiet. Shack ambient about +20C (68F). At that time some hotly recommended that the correct way to orient the fan was to place it directly on the heat sink sucking air through the fins. I tried this but did not find this to be the most effective solution. My logic, if you can call it that, is simply if I am faced with a hot object, say a spoon full of soup, if I want to cool it a little I blow gently on it, not try and suck air from all around it. Whatever, I'm not going to die in a ditch over it. I only used this arrangement for the rather extended duration of the tests. Normal DXing which at the time netted me 200+ DXCC before I built a K3 seldom activated the little screamer. I can email you a picture of the setup if you wish.

[...] blowing down on it at Hi Mike, That makes all sorts of sense. Because the fan can blow much harder on the heatsink than it can suck off of it. The power of sucking is limited by the ambient air pressure, whereas the power of blowing is unlimited. I had a similar issue with my shallow irrigation water well. Needed to clean it out with a water pump. The pump could not suck water out of the well because the water was at 26 feet below grade, which is the absolute max that any pump - no matter how fancy or expensive - could suck upwards. Because the force pushing that water up was just ambient air pressure. The fix was to use a submersible sewage pump and a sandbag. - Jerry KF6VB From rick at tavan.com Sun Aug 8 11:11:40 2021 From: rick at tavan.com (Rick Tavan) Date: Sun, 8 Aug 2021 08:11:40 -0700 Subject: [Elecraft] K4D in NAQP - Little Things I Liked Message-ID: Although I've been field testing the K4D for quite a while now, I still find little things to marvel at. In this weekend's NAQP CW, for instance, I really appreciated these gems: - Logging with N1MM, operating SO2V (single operator, 2 VFOs), I often tap the tilde/grave key to turn the sub-receiver on and off. With K3 and some non-Elecraft radios, this doesn't work or doesn't work very well *when transmitting*, but I often want to change sub-rx state in anticipation of message completion. With my K4D, it always worked. Sometimes it didn't take effect instantly, but within a second or so the SUB LED would change state and at the end of my transmission the sub-rx was always in the desired state. Very slick. - The mini-pan was very valuable to keep an eye on my run frequency. I could see encroaching signals, even sometimes when I couldn't hear them, and adapt my CQ timing or even my frequency slightly to meet the challenge. - The main panadapter Rx A and B cursors move smoothly while transmitting, even though the spectrum display and waterfall are appropriately frozen on the signals that were present at the beginning of the transmission. That let me tune in the next signal I wanted to check out, typically on the sub-rx, before message transmission completed, typically on the main rx frequency. With or without QSK (or semi-breakin with Delay=0), this was a big time saver. - The K*Pod worked well. I rarely had to reach out and touch the radio. I had implemented Band Up and Band Down buttons that work almost like the BAND rocker switch on K3. Still can't map out unused bands, but I think that will happen eventually. Meanwhile, it's sometimes two taps instead of one, not a big deal. This was using the latest field test software release, which will go to public beta Real Soon Now, but I think most of these capabilities have been in prior public releases. K4 is an SDR, so it will continue to evolve for years to come. But the ergonomics are already quite good. K4 wait-listers - hang in there; good things are coming! 73, /Rick N6XI -- Rick Tavan Truckee and Saratoga, CA From goldporsche944 at aol.com Sun Aug 8 11:30:43 2021 From: goldporsche944 at aol.com (Richard Isaacs) Date: Sun, 8 Aug 2021 11:30:43 -0400 Subject: [Elecraft] K3 dilemma update.

If you attempted to adjust KPA100 C1 while this condition was present, balance the wattmeter again, it will change with good diodes installed. The diodes are 1N5711 type. That wattmeter is still used as long as the KPA100 is installed on the base K2 - reducing the power to less than 12 watts does not take it out of line. CAL CUR should be set at 3.5 amperes with the KPA100 installed. That (and the current display) is the current drawn by only the base K2, and not to the KPA100. 73, Don W3FPR On 8/8/2021 12:24 PM, jerry wrote: > All, > > ?

My neighbor, K6XX, is the engineer at Elecraft tasked with putting the KPA1500 into production. He got burned out (lost everything) in last summer's wildfire, and borrowed my KPA1500 for a weekend contest. I had done what you suggest, because I work lots of FT8 on 6M. I told him the fans in the RF deck were sounding funny. Ge said when he opened it up, the fans were full of dust. Bob told me to set the lowest fan speed to zero, and let the firmware adjust as needed. I've been doing that for a year, with no issues. Running at 1.1kW on 6M WSJT modes (his recommendation), the fans speed up to keep indicated temp below around 63 C. During heavy RTTY contesting at 1.5kW, it will hit 90 C. He says no problem. 73, Jim K9YC From rmcgraw at benlomand.net Sun Aug 8 14:21:26 2021 From: rmcgraw at benlomand.net (Bob McGraw) Date: Sun, 8 Aug 2021 13:21:26 -0500 Subject: [Elecraft] Elecraft Digest, Vol 208, Issue 4 In-Reply-To: References: Message-ID: <111e8f60-b494-8155-17a6-b6ef271b9e70@benlomand.net> Check to see that the correct antenna is selected on the K3.

My first Tiny Linear ( for its day ) project was an ARC-5 transmitter cabinet crammed full of 6LQ6 tubes. I tried it at first without a fan...and it burst into flames! So I mounted a 120v muffin fan right on top, and it ran cool as a cucumber. But loud. REALLY loud.

With K3 and some non-Elecraft radios, this doesn't work or doesn't work very well when transmitting, but I often want to change sub-rx state in anticipation of message completion. With my K4D, it always worked. Sometimes it didn't take effect instantly, but within a second or so the SUB LED would change state and at the end of my transmission the sub-rx was always in the desired state. Very slick. > The mini-pan was very valuable to keep an eye on my run frequency. I could see encroaching signals, even sometimes when I couldn't hear them, and adapt my CQ timing or even my frequency slightly to meet the challenge. > The main panadapter Rx A and B cursors move smoothly while transmitting, even though the spectrum display and waterfall are appropriately frozen on the signals that were present at the beginning of the transmission. That let me tune in the next signal I wanted to check out, typically on the sub-rx, before message transmission completed, typically on the main rx frequency. With or without QSK (or semi-breakin with Delay=0), this was a big time saver. > The K*Pod worked well. I rarely had to reach out and touch the radio. I had implemented Band Up and Band Down buttons that work almost like the BAND rocker switch on K3. Still can't map out unused bands, but I think that will happen eventually. Meanwhile, it's sometimes two taps instead of one, not a big deal. > This was using the latest field test software release, which will go to public beta Real Soon Now, but I think most of these capabilities have been in prior public releases.

I have those in abundance now, more than I need. But I run them on 9 vdc with no trouble (wall warts and such) or from the 12 vdc I might be using for a rig. I use those fans on top of my Drake tube gear with the open perforated cabinets and so on. I have boatanchor rigs I also blow air into or out of when running them in the shack in the winter months (my basement is not conducive to tube gear operation in the summer!). As they are free and are pretty darn quiet (especially at 9 vdc) they are useful to have at hand for any situation where heat might need to be dealt with.

I don't know if you are familiar with Mark, W7MLG's, measurements on the Kenwood TS-590 TCXO. If not, you can find his results here: https://sites.google.com/site/markstcxomeasurements/ You don't need any fancy test equipment to get an idea of how bad these Chinese "TCXO" may be. My simple test produced results that were in good agreement with Mark's data. My report documents my test method as follows: "Test conditions and method: TS-590S (B1B00046 with various oscillators) transmits 88 W CW to dummy load with sniffer port TX at 14.100 CW with "k3wyc" TS-590S (B4500305 with various oscillators) acts as receiver of sniffer port via step attenuator RX at 14.115 (+15k) with various DSP bandwidths to force up or down conversion Start with low attenuator setting Increase attenuator setting until CW noise signature is not readable (CW noise signature is at RX noise floor).

At first I noticed that my Amp would put out only about 70-80 Watts. Then the output went lower and lower until the Amp would not turn on. See below. Here follows what I know at this stage: The AWG 10 power cable from my ASTRON 35A PS to my Elecraft KPA100 amp is about four feet long. At the terminals on the PS I measure 13.83 v and I measure exactly the same at the cable?s end?s Anderson PowerPoles. (The back of the amp accepts only Anderson PowerPoles.) There are two sets of these PowerPoles, and the manual for the amp suggests using the lower set for the Amp, and that?s what I have done. The manual recommends plugging in the KX3 on the upper PowerPoles, and I have done that as well. And the radio turns on, no matter whether the Amp is working or not. To turn on the Amp I have to go to the Menu on the KX3, and rotate the knob above the Menu button until I see ?PA OFF.? Then I turn the main VFO knob until the OFF changes to ?ON.? Some Indicator LEDs on the amp turn on: ON (indicating the Amp has been turned on) ANT 1 (indicating Antenna 1, the one I use to go to the antenna) Mode MAN (indicating manual control?which I wish indicated Auto, for automatic control) FAULT (indicating SYS (I presume this stands for System) for which I could find no helpful explanation in the manual). After about 10 seconds the Amp turns off! I need the Amp to turn on so that I can use the KPA100 Utility Program to do any troubleshooting, but that is not possible, since the Amp will not remain on for longer than those ten seconds I mentioned above. Without the amp I can use my KX3 rig at up to 15W and can use the KP3 panadapter as well, so all is not lost! The harnessed set of cables connecting the Amp, the KX3, and the KP3 all go through the Amp, and they show they are doing their job of connecting the KX3 with the KP3. I just had a very nice CW QSO with a station in Massachusetts and the reports were 599 both ways. Joy! All of my cables are fairly well dressed, with no desktop clutter. I don?t know what to do next.

Things are still not right. I did get a good adjustment on C1, and it now reads 1 to 1 on all bands. HOWEVER, it still will not give full power. It fails with "HiCUR". If the KPA100 is installed but not powered up ( power from the barrel connector ), it gets to about 8W then fails "HiCUR". If the KPA100 is installed AND powered up AND enabled via the menu: on 40M, it gets to a bit over 80W, then says "HiCUR". on 20M it gets to about 65W, then "HiCUR" If I uninstall the KP100 completely, the radio gives full power - 15.3W on 20M, 16.7W on 40M. Very mystifying. I made up a cord to connect the barrel connector to my lab supply. Interesting results: with the KPA100 connected but power through the barrel, the radio simply does draw enough current to shut it down with "HiCUR" at 8W. It shuts down at EXACTLY 3.5A measured by the power supply. With the KPA100 entirely disconnected, the radio makes 16W on 40M at 3.15A. So my conclusion is that something in the KPA100 is drawing excess current, in transmit mode, even though the KPA100 is mostly not operating. In "tune" with the power all the way down, and the KPA100 connected, the radio draws 750mA through the barrel connector. In "tune" with the power all the way down, and the KPA100 DISCONNECTED, the radio draws 440mA through the barrel connector. - Jerry KF6VB > If you attempted to adjust KPA100 C1 while this condition was present, > balance the wattmeter again, it will change with good diodes > installed. > The diodes are 1N5711 type. > > That wattmeter is still used as long as the KPA100 is installed on the > base K2 - reducing the power to less than 12 watts does not take it > out of line. > > CAL CUR should be set at 3.5 amperes with the KPA100 installed.

Just as a diagnostic step, try turning the amp on with its power slide switch. It should stay on. To avoid needing to use that slide switch all the time, there is a serial command sent periodically from the KX3 to the amp telling it to switch on. That command must be repeatedly received to keep the amp on. If your serial cable is intermittent (not fully seated?) all the KX3 messages may not be arriving at the amp, and the amp turns itself off after a period of silence from the KX3. Another serial cable might also be helpful. Good luck! 73 de Dick, K6KR > On Aug 12, 2021, at 09:45, Carter Craigie wrote: > > ?

I would suggest you first try 5 watts, and operate at that level for a while (I suggest 10 minutes). Then check the heatsink temperature - if you can hold your fingers on it for longer than 5 minutes, then all is well. Increase the power by about 3 watts and try again. When the heat gets too much to comfortably hold your fingers on the heatsink (next to the PA transistors), then you have exceeded the maximum power which you should use for transmit. The generalized answer is that you should consider those modes as continuous duty and use 1/2 the normal full power output, but I suggest doing the test I referred to as a specific power limit for your particular K2. 73, Don W3FPR On 8/13/2021 3:38 PM, Aaron K5ATG wrote: > What is the recommended highest power level for a QRP Elecraft K2 to > operate on digital modes like FT8, JT65 etc, without blowing the PA's? > From jim at audiosystemsgroup.com Fri Aug 13 19:29:39 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Fri, 13 Aug 2021 16:29:39 -0700 Subject: [Elecraft] K3 control software?

In-Reply-To: References: Message-ID: I use a variety of things depending on what I want to do. I often run Win4k3 connected to the radio, and then other software like N1MM, DxLab, etc. connected to the 'virtual radios' of Win4K3 via virtual serial port pairs. I have found this a reliable way to allow multiple programs to each 'think' they are directly controlling the K3, while they are all being kept in sync. In other words, changing frequency. mode, etc on the radio or in one of the connected programs causes it to change everywhere. Other times I just run N1MM or DxLab Commander connected directly to the K3. Or I'll connect N1MM to the K3, and then run WSJT-X from within N1MM, so it logs directly into N1MM. All depends on what you're trying to accomplish. If you can articulate what your goals are, there are many here who can give you good advice on what to use to get there!

You said "Both read and write". Does that mean you need the software to decode the received CW as well as send it? Win4K3 includes a 'terminal' function that can use the built-in CW encode/decode capability of the K3. You can set up macros, and it can log to its own log file or optionally to DxLab DXKeeper, Log4OM, or Ham Radio Deluxe.It basically sends the characters from your keyboard to the K3 which converts them to CW on transmit, and displays on the screen the text the K3 has decoded on receive. Win4K3 requires payment, but is worth it in my opinion for the many capabilities it provides. DxLab includes WinWarbler which can send CW in several different ways, and includes macros. It can display decoded CW directly from the decoder in the K3 or from a couple other software CW decoders. It also logs to its own DXKeeper logging program. DXLab is completely free, and is incredibly well supported by its author. I use it for DXing and as my master log, among other things. N1MM can send CW in at least a couple of ways, and includes macros. Even though it's primary purpose is contesting, it can also be used as a general DX logging program. I don't know whether it has any CW decode abilities. I use N1MM mostly for contesting, and I use a clone Winkeyer with it for CW keying. I'm sure there are plenty more possibilities, However, my experience with machine decoding of CW has not been very good. If the CW signal is strong and the timing is good, and there's not much QRM, they do ok. I have yet to see one that does as well as the decoder between the ears. That should at least give you some ideas to explore. 73 de W0ZF On Sat, Aug 14, 2021 at 12:26 PM Bruce Wade wrote: > Tnx for the input.

It has the A to B mods applied, and includes the options for SSB, DSP, 160/Rx ant, etc. I have applied the BFO and PLL upgrades. My current problem is that the RF gain knob doesn?t seem to do anything. I was expecting to hear some difference in the level of received signals and to see the S-meter go to the right as I turn the knob fully CCW. Turning this knob seems to have no affect on anything. Any help would be appreciated! I mention the following details in case they are relevant: my father was mostly interested in 160m cw, so I?m not sure if other aspects of the radio received attention when he built it. The AF gain knob is scratchy - I?ve read about the mod that addresses this, but haven?t yet applied it. The AGC needs adjustment - I can tell the difference in volume AGC On vs off with no antenna connected. I don?t know that any of these are related to the RF gain. Before I open things up to measure and replace the RF gain pot, are there other things I should check? A quick check of the email reflector archive didn?t turn up anything obvious to me. 73, Mike AE6NH From markmusick at outlook.com Mon Aug 16 10:46:34 2021 From: markmusick at outlook.com (Mark Musick) Date: Mon, 16 Aug 2021 14:46:34 +0000 Subject: [Elecraft] Any update on production of K3 ugprade parts production/delivery?

Here is my reply to him. They announced a few weeks ago that they were closing the order list and there would be no more production runs for K3 options. They indicated at that time it would be about 12 weeks before we could expect delivery. It isn't even close to 12 weeks. What more of an update are you looking for? I finalized my order and gave them half deposit. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Henk PA5KT via Elecraft Sent: Monday, August 16, 2021 14:07 To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Any update on production of K3 ugprade parts production/delivery?

It is not likely that replacing the pot will fix it. For a scratchy AF Gain control, replace the control, as well as doing the Alternate AF Gain Wiring Modification.?

I would suggest you first try 5 watts, and operate at that level for a while (I suggest 10 minutes). Then check the heatsink temperature - if you can hold your fingers on it for longer than 5 minutes, then all is well. Increase the power by about 3 watts and try again. When the heat gets too much to comfortably hold your fingers on the heatsink (next to the PA transistors), then you have exceeded the maximum power which you should use for transmit. The generalized answer is that you should consider those modes as continuous duty and use 1/2 the normal full power output, but I suggest doing the test I referred to as a specific power limit for your particular K2. 73, Don W3FPR On 8/13/2021 3:38 PM, Aaron K5ATG wrote: > What is the recommended highest power level for a QRP Elecraft K2 to > operate on digital modes like FT8, JT65 etc, without blowing the PA's? > From frantz at pwpconsult.com Mon Aug 16 16:04:33 2021 From: frantz at pwpconsult.com (Bill Frantz) Date: Mon, 16 Aug 2021 16:04:33 -0400 Subject: [Elecraft] T1 Tuner Question ?

I never thought of the "finger test" for that purpose, but the "Threshold of Pain" is normally considered to be 42C (or 107F). My KPA500 reaches that temp after about 8 seconds of 40 meter carrier with a drive level of 18 watts and an output level of about 350 watts. (Normal 'power off temp' runs about 37C).

The generalized answer is that you should consider those modes as continuous duty and use 1/2 the normal full power output, but I suggest doing the test I referred to as a specific power limit for your particular K2. 73, Don W3FPR On 8/13/2021 3:38 PM, Aaron K5ATG wrote: > What is the recommended highest power level for a QRP Elecraft K2 to > operate on digital modes like FT8, JT65 etc, without blowing the PA's? > ______________________________________________________________ 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 lyn at lnainc.com From Lyn at LNAINC.com Mon Aug 16 16:39:09 2021 From: Lyn at LNAINC.com (Lyn Norstad) Date: Mon, 16 Aug 2021 15:39:09 -0500 Subject: [Elecraft] K4 delivery status In-Reply-To: <7195d9f4-7f77-543d-ed85-7061c270b41e@foothill.net> References: <7195d9f4-7f77-543d-ed85-7061c270b41e@foothill.net> Message-ID: <060801d792de$c5302220$4f906660$@LNAINC.com> Fred - According to QRZ, you are 3 years older than I am ... and I am one year beyond the current "Average Life Expectancy" in the USA (post-Covid) for men.

I would suggest you first try 5 watts, and operate at that level for a while (I suggest 10 minutes). Then check the heatsink temperature - if you can hold your fingers on it for longer than 5 minutes, then all is well. Increase the power by about 3 watts and try again.

My K3 [#642] is getting somewhat long in the tooth but it still functions great and I really enjoy it.? I've also had enough time to learn how to use most of the knobs and switches.? The two primary questions lurking in my head right now: 1.? I run W7RN remotely with the RemoteRig RRC-1258 setup and my K3.? If I replace my K3 with a K4, and Tom does _not_ do likewise at RN, will my remote setup still work? 2.? I have monochrome vision.? I run my P3 waterfall in monochrome mode [Thank you Alan!] since the colored mode makes no sense to me.? Does the K4 offer that same monochrome WF option?

I am finally finding some time again for ham radio and would like to get this rig up and working well. It has the A to B mods applied, and includes the options for SSB, DSP, 160/Rx ant, etc. I have applied the BFO and PLL upgrades. >> >> My current problem is that the RF gain knob doesn?t seem to do anything.

Turning this knob seems to have no affect on anything. >> >> Any help would be appreciated! I mention the following details in case they are relevant: my father was mostly interested in 160m cw, so I?m not sure if other aspects of the radio received attention when he built it. The AF gain knob is scratchy - I?ve read about the mod that addresses this, but haven?t yet applied it. The AGC needs adjustment - I can tell the difference in volume AGC On vs off with no antenna connected. I don?t know that any of these are related to the RF gain. >> >> Before I open things up to measure and replace the RF gain pot, are there other things I should check?

The world-wide chip shortage (and other factors beyond Elecraft's control) make providing reasonable delivery estimates nearly impossible. This applies to many products including autos, not just the K4. Most Elecraft K4 discussion is taking place on an independent moderated mailing list with almost 1,000 members: https://groups.io/g/Elecraft-K4/topics. I cannot read this Elecraft mailman reflector regularly because I'm spending most of my time in that dedicated K4 group, not here. You can search the group for answers to common questions, such as K4 Remote support (still under development). *K4 shipping status and delivery questions should be posted to separate dedicated groups* that are trying to estimate Elecraft's ship rate based on serial numbers and public reports. https://groups.io/g/CreativeK4ShippingStatus/topics https://groups.io/g/Elecraft-K4DeliveryInformation/topics And of course the official Elecraft page is here: https://elecraft.com/pages/shipping-status Note that "Group 1 K4D June 24th" means June 24th, *2019*. 73, Bob, N6TV From bbaines at mac.com Mon Aug 16 20:55:01 2021 From: bbaines at mac.com (Barry Baines) Date: Mon, 16 Aug 2021 20:55:01 -0400 Subject: [Elecraft] K4 delivery status In-Reply-To: <82e429d8-0663-ec7c-109e-021cc744c5b6@gmail.com> References: <7195d9f4-7f77-543d-ed85-7061c270b41e@foothill.net> <060801d792de$c5302220$4f906660$@LNAINC.com> <728440a3-f94c-c4f7-dc35-625216b53af0@foothill.net> <82e429d8-0663-ec7c-109e-021cc744c5b6@gmail.com> Message-ID: David: > On Aug 16, 2021, at 7:28 PM, David Gilbert wrote: > > > Apparently not.

The only replies I got said that Elecraft had not yet written a release version of the software for remote operation of the K4, and as best they could tell from the responses they had gotten from Elecraft there was no timetable for doing so. Nobody from Elecraft bothered to answer my query, so they are probably correct. We all know that Elecraft is facing huge challenges on all fronts in terms of product manufacturing and digging through the orders they?ve received. Elecraft is not alone in terms of announcing a vision and then expending the resources ($$$, technical development, production, distribution) to make it happen. Elecraft?s new vision is not easy to implement and will take time (years) to fulfill what has been announced. The challenge is to provide a roadmap and then calibrate everyone?s expectations regarding when these new capabilities will be available to users. Like FlexRadio, Elecraft is building a new product line (?ecosystem?) that is fundamentally changing their product offereings and thus the user experience. While I?m not suggesting that Elecraft?s ability to fulfill its roadmap mirrors the customer experience at FlexRadio, making the comparison at least provides a potential for context and recognizing that the technical and financial challenges can be significant. In addition, events of the past 18 months has certainly impacted Elecraft more than Flex in terms of new product releases given what California has been going through not only with Covid-19 but fires and power outages along with subcontractor issues, parts issues, etc. So with these thoughts in mind, I can recite my personal experience as an ?early adopter? of the Flex-6000 series and the timeframes of what was promised and when it was delivered as I can recall offhand. 1. Hamvention 2012 was when Flex announced the Flex-6700 transceiver and the evolution into a ?client-server? typography between radio (server) and connection device (PC, other user interface) as the client. What caught my eye was the promise of remote operation via an ethernet connection that would greatly simplify the setup and operation of a remote station. Given that my potential operating would be 90% of the time via remote operation, this was a big deal to me. I ordered one in August 2012 as their ?early purchase discount? was expiring. 2. My Flex-6700 was delivered in November 2013 with SmarSDR v1.x that was essentially useless for my purposes. No provision for remote operation and only ?basic functions.? No promises were made as to when remote operation would be possible. 3. In August 2014 I purchased the K3-KPA500-KAT500-K3/I0 mini with remote rig system from Elecraft at the Huntsville Hamfest. 10 days later product was delivered to me in Westborough, MA and I subsequently set it up at my station in Folkston, GA over labor day weekend. I ordered the equipment because at this point I had no idea when Flex would have developed their remote capability and none of us were getting any younger. Setup was simple and ?it simply worked?. Nothing fancy versus the potential of the Flex, but it performed as advertised. Most importantly, i had a reliable remote station capability. 4. In May 2017 Flex announced SmartSDR v2.x with ?Smartlink? that finally provided the wide area network remote capability that I was looking for. Note that this was FIVE YEARS after initial product announcement. By then SmartSDR had evolved to a level of maturity where the capabilities were meeting expectations?. 5. In February 2018 Flex announced the PGXL amplifier along with an external tuner capable of SO2R capability that would handle the output of the PGXL. The PGXL was shown at the Orlando Hamcation but the tuner at this point was ?vapor? as it had not yet been designed. I ordered mine the day that Hamcation opened. 6. I received my PGXL in May 2018 following Hamvention. Neither SmartSDR nor the Maestro were updated to accommodate the PGXL, so I was forced to use the PGXL using the PGXL utility running on a PC in the shack when operating remotely. More significantly, no tuner was announced so at this point I could use the amplifier with my tribander. This meant that I was dependent upon the Elecraft equipment for bands other than 10-15-20. 7. The amplifier was returned to Flex in December 2018 due to warranty recall (issue with six meters). 8. I don?t remember when, but PGXL integration was incorporated into both Maestro and the various SmartSDR iterations, making it much easier to manage the PGXL remotely. 9. The TGXL (Tuner Genius) was announced in March 2021. I received my Tuner Genius in June 2021, 3+ years after I ordered the PGXL and tuner package. 10. With the release of TGXL, a TGXL utility was also released providing ?basic? remote operability to manage the Tuner. No word as of today as to when the TGXL will be integrated into SmartSDR or Maestro. It does integrate with Antenna Genius if you have the SO2R version of TGXL. In fairness to Flex, a number of cool capabilities were developed by Flex and third parties over the past four years including SmartSDR for Mac, DogPark SDR, SmartSDR for iOS (iPhone and iPad) and various utilities. Flex has actively encouraged developers to use their API to create new features/capabilities for the Flex-6xxx ?ecosystem.' In essence, it has taken Flex and others nine years to develop a Flex-6xxxx ?ecosystem? of very tremendous capability that covers the entire operator HF experience. With transverters, this experience can be extended to VHF and above. The system has matured to the point where the equipment ?works? and fulfills their vision of remote capability. As third parties develop new features (including Node Red systems), the potential is endless. I personally see Elecraft?s K4 as having similar potential. I don?t doubt for a moment the dedication and vision that Eric and Wayne possess in their efforts to bring the K4 ?ecosystem? to fruition. Hopefully, their vision will be completed more expeditiously than Flex, but I also suspect that they?re following a multi-year evolutionary process given their current challenges? I also suspect that there will be the potential for third parties to develop products that will enhance the K4 experience over time.

As an aside, last I checked software development wasn't dependent upon piece part supply.? Priorities are priorities, though ... I'm just saying that the remote capability doesn't appear to be very high on the list.? That's obviously Elecraft's choice, but for me the remote capability was probably the one key attribute that might convince me to switch from my K3 to the K4.? For everything else that actually matters to me in the way of raw performance, the K3 seems as good or better. 73, Dave??

Priorities are priorities, though ... I'm just saying that the remote capability doesn't appear to be very high on the list. That's obviously Elecraft's choice, but for me the remote capability was probably the one key attribute that might convince me to switch from my K3 to the K4. For everything else that actually matters to me in the way of raw performance, the K3 seems as good or better. Perhaps you?re missing my point. Yes, hardware production is dependent upon parts supply, but the focus of development is software both in terms of user interface as well as the ?internals? of managing ?Software" Defined Radio systems is significantly greater than prior Elecraft products. It took Flex nearly five years after initial product announcement to provide Wide Area Network remote capability for their Flex-6xxxx products. When it came out in 2017, it changed the entire nature of Flex products. Remote operation is what is driving Flex users today. Elecraft presumably understands this, but clearly there are other software development concerns they?re currently focusing upon. And how do you balance the need to get hardware product out-the-door (to generate revenue) versus software development that has been implicitly promised but is presumably initially paid for with a hardware purchase? The priority is presumably to get product out-the-door? And as good as job as Elecraft did on K4 software development before product release, there will be ?bugs? found by users as the user base expands. Thus, there is also a continuing need for ?software maintenance.? I have no idea what ?software licensing? model Elecraft may pursue down the road. Will ?remote operation? be a separate product to be purchased when it is available? The version of SmartSDR that users obtained when they received their Flex-6xxx eventually was replaced by an ?enhanced? version that offers new features with a new version number that requires payment for a new license if the user wants the enhanced capabilities. The license is associated with the radio, not the user. Thus, I went from v1.xxx when the Flex was delivered in November 2013 and later paid for v2.xxx when "Smartlink? (Remote operation) was introduced in 2017. Later, Flex offered ?Multiflex? under SmartSDR v3.xxx that I elected not to purchase and my current SmartSDR v2.7.6 supports my current needs. ?Versions? reflect new capabilities (e.g. ?Smartlink? and ?Multiflex?) while bug fixes within a version are provided as part of the existing license. This pricing model is common in the computer industry and it does provide a revenue stream to help support continued software development. In addition, I paid for SmartSDR for Mac and SmartSDR for iOS licenses developed outside of Flex because they offer features I was willing to pay for with the developer promising future updates without additional fees. Thus, don?t overlook the significance of software development both in terms of development time and expense. I presume that the software development effort for the K4 is significantly greater than prior Elecraft products requiring special skills (such as FPGA programming) and more extensive development efforts than in the past that takes time and resources to successfully implement.

I have no idea where they stand on their development work or where it stands in their priority list. I suspect that they?re dealing with more critical priorities, like it or not. I referenced the ?Flex experience? because it seems to me that it a reflection of how product development has changed in the amateur radio industry. No longer do manufacturers come out with a HF rig every few years with the latest features (that can?t be upgraded later). Instead, they?re developing a new ?ecosystem? that presumably will last for a number of years where new features are introduced as ?software updates? rather than as hardware enhancements in the guise of a new model. This approach suggests that the product will ?mature? over time and that it may take a number of years to reach what was initially ?promised? under the vision that was announced when the product introduction was made. It may also be the case that capabilities not announced upon product announcement may be introduced such as ?MultiFlex? where two operators are sharing the same transceiver at the same time (but only one is transmitting at a given instant). SDR development in particular is not trivial requiring specialized skills and where resources may be constrained that will lengthen development time. Furthermore, under the adage of ?the perfect is the enemy of the good?, hardware will be released with software embedded that may not provide even ?basic? features that clearly should be included. Flex did this with SmartSDR v1.xx. They sold the transceiver as being ?remotable? but it took them five years to provide that capability. The delay was likely due to higher priorities (to provide the features that everyone, not just remote operators, needed) and more complex challenges (such as providing appropriate security to prevent unauthorized use of an amateur transceiver that can only transmit under the control of an authorized licensee). Demoing remote operation is not the same as a general release where security features must be built-in to ensure station security. I suspect that the development efforts under Flex are a reflection of the challenges now faced by Elecraft recognizing that there are significant differences in equipment architecture but both push the SDR envelope to provide the richest experience as perceived by each manufacturer. I?m not predicting that it will take Elecraft five years to provide a remote operation option. I am suggesting that it may be ?awhile? as it isn?t clear what they expect to provide. It may be app(s) that runs on Windows or Mac or iOS or Android or it may also include a hardware equivalent (K4/i0) or they will provide an API that developers can use to access the K4 feature set. I?m not following the K4 ?story? close enough to know exactly what their current thinking is on this matter. I do intend to attend the Huntsville Hamfest this coming weekend, so perhaps I?ll have a better understanding of their current situation after visiting the Elecraft booth. Lastly, the benefit of being an ?early adopter? is that the user benefits from the development efforts to date. Clearly, the K4 is a significant upgrade over the K3 as currently demonstrated The downside is potential frustration as desired features are not available immediately upon initial product shipment and it could be ?sometime? before the full potential of a product is reached. I considered my Flex-6700 to be a ?paperweight? for five years because it was not remote-able while others who were using their Flex transceivers locally were very satisfied with what was being provided at the time. I purchased the K3 system in the interim to give me some level of remote capability. Now that the Flex system has matured to the point where I can fully utilize it as a remote station, the K3 is now serving as a ?backup? system which is very important given that I?m usually over 1200 miles from the ham site for months at a time. I have a Flex Maestro sitting next to my K3/I0-mini at two locations which combined with how I have remote power management setup allows full control of my ham station. I?ve had situations where the Flex is not available (usually due to a configuration mistake on my part that isn?t discovered until after I leave the site or a hardware failure such as a bad LAN switch or failed UPS) but the Elecraft is fully operable because it is not physically dependent upon the same LAN switch or UPS network backup. ?Redundancy? is a good thing when using a remote station. 73, Barry, WD4ASW/1 > > Dave AB7E > > > On 8/16/2021 8:33 PM, Barry Baines wrote: >> David: >> >>> On Aug 16, 2021, at 10:27 PM, David Gilbert wrote: >>> >>> >>> Well, I'm not particularly interested in Flex's history, but that seems to be a pretty long winded agreement that there probably isn't any timetable for the remote capability that Elecraft appeared to demonstrate in their video upon the release of the K4. >>> >>> As an aside, last I checked software development wasn't dependent upon piece part supply.

The version of SmartSDR that users obtained when they received their Flex-6xxx eventually was replaced by an ?enhanced? version that offers new features with a new version number that requires payment for a new license if the user wants the enhanced capabilities. The license is associated with the radio, not the user. Thus, I went from v1.xxx when the Flex was delivered in November 2013 and later paid for v2.xxx when "Smartlink? (Remote operation) was introduced in 2017. Later, Flex offered ?Multiflex? under SmartSDR v3.xxx that I elected not to purchase and my current SmartSDR v2.7.6 supports my current needs. ?Versions? reflect new capabilities (e.g. ?Smartlink? and ?Multiflex?) while bug fixes within a version are provided as part of the existing license. This pricing model is common in the computer industry and it does provide a revenue stream to help support continued software development.

I had had a problem with my KXPA100 amplifier, and, indeed, after struggling to get it working again after I had moved my KX3, PX3, and that amp from one floor of our home up to another. The amp appeared to be either ?dead,? or nearing ?death.? I tried everything I could think of for a complete week, but kept being defeated. It was at that point I threw in the sponge and requested help from Support at Elecraft. After some time Rob sent me an email, and then we exchanged emails for several hours. Then he suggested I telephone him, and Receptionist Michelle quickly connected us. And then my situation started to improve and improve. Rob suggested I disconnect, and then to reconnect all the various cables, making quite sure I had them all seated properly. At one point he had me take a sharp inspection of all the plugs themselves, to make sure they were in proper shape. He suggested I use an RCA plug and cable (which I cobbled together as quickly as I could) to ensure the TX LED would light up properly, and it DID. Rob then helped me understand why my ON/OFF LED was flashing (I had my KX3 set with too low a power request) and how to fix that. Next he ?held my hand? working with me to recalibrate the amp?s internal ATU settings. He was VERY patient, as I used my dummy load to go through each and every band, to bring the output up to the 75 Watts he told me to set on the KX3. (Those instructions were on page 52, I believe, in the KXPA100 manual?which I had never read!) We finally signed off our telephone conversation when Rob made sure I was as happy as could be! I know this Thank You Recognition is long, but there will be those who might have asked how my ?dead? KXPA100 amp was brought back to life. Wayne and Eric, please let Rob know you have read my Thank You note here. He was , and must be, outstanding, and a big credit to Elecraft. 73, Carter Craigie, N3AO Blacksburg, VA SATISFIED CUSTOMER -- Carter, N3AO Blacksburg, VA From radiok4ia at gmail.com Tue Aug 17 07:59:01 2021 From: radiok4ia at gmail.com (Buck) Date: Tue, 17 Aug 2021 07:59:01 -0400 Subject: [Elecraft] K4 In-Reply-To: References: <2058860030.935911.1629149970992.ref@mail.yahoo.com> <2058860030.935911.1629149970992@mail.yahoo.com> Message-ID: If you don't travel first class, your kids will.

Release of the KPA1500 was delayed by the need to fix an issue on 6M. I learned this from someone in a Visalia booth. Mine has been working flawlessly for more than a year. Prior to that, I made extensive use of a KPA500 and KAT500, and still use them for county expeditions.

They make them in a number of configurations and some have a remote control. The way they work is that you can have multiple inputs (from PC, K4, Laptop, etc) and then a single output that goes to one of your monitors. You can then use the remote to switch between the different sources for that monitor.

Currently it happens only on 20M, 40M seems fine, haven't checked the others yet. > Mike, AB3VN > From jowoc1 at gmail.com Thu Aug 19 17:23:07 2021 From: jowoc1 at gmail.com (Zbigniew Tyrlik) Date: Thu, 19 Aug 2021 17:23:07 -0400 Subject: [Elecraft] K4 video - what display is in use Message-ID: <052E014D-D732-457E-8DEE-F2454687E0A7@gmail.com> Anyone knows what is the thin display ( I think LCD ) used by Eric in the latest K4 YouTube video ?

One USB-C cable to the external screen would supply not only video and power, but could enable touch screen capabilities, allowing the user to control the rig from the much larger screen if desired. I'm not sure if any code changes would even be needed to enable the touch screen support, since the rig already supports it on its internal screen. As it stands, you could probably get the touch screen to work using a USB/USBC adapter, but now you've got 3 cables for that external screen instead of one. I really hope Elecraft gets the USB-C upgrade into the backlog soon. Tim On Thu, Aug 19, 2021 at 2:32 PM Dave Van Wallaghen wrote: > It is a Niuto 14" TouchPad.

The touchscreen works FB especially when the external monitor is mapped to mirror the K4 screen. But a change to an upcoming beta release of the K4 software allows the touchscreen to work when the external monitor is mapped as a panadapter allowing you to select desired signals on the screen and QSY the K4.

But this 60Hz offset will still be present. Then no matter how you tune at the coarse setting, you will mistune. To fix that you should always reset the fine tuning offsets to zero before switching to coarse. It is apparently a bug in the software because the normal expectation would be to reset all fine offsets to zero automatically after switching to coarse tuning.

Or is there something > else that would be needed? *** Not sure about the KIO2, but I did peruse the data on the serial port included on the KPA100, which is probably the same. In the case of the KPA100, you MUST use a custom cable - either supplied by Elecraft, or made up with their schematic. This is because Elecraft used "spare" pins on the serial connector for things that have nothing to do with serial communications. For serial comm, you connect ONLY pins 2,3 and 5 on the 9-pin serial connector. pin 2 is TxD ( data from the K2 to the computer ), pin 3 is RxD ( data from the computer to the K2 ), and pin 5 is the common/ground. Again, this is specific to the KPA100; I don't know if it applies also to the KIO2, but I suspect that it does. - Jerry KF6VB From 99sunset at gmail.com Mon Aug 23 15:00:35 2021 From: 99sunset at gmail.com (Steve Hall) Date: Mon, 23 Aug 2021 15:00:35 -0400 Subject: [Elecraft] 40 METER NET / 80 METER NET 8-22-21 Message-ID: Thanks to all that assisted with relays. 40 METERS 7.280 1900Z WM6P STEVE GA K3S NETCONTROL W9EJB ED IN K3 K9NU CARL OH FTDX101D K5PD PETER TX K3 W3SA JOHN NC TS890 WY3T TIM FL K3S W8UAN TIM MI TS-890 NC0JW JIM CO KX3 WN3T RICK VA IC7610 K8IGU BRIAN OHIO TS2000 KD9QDP RICK IL TS450 N3RFO LES MD IC7300 KC3HW JIM PA IC7300 W2JHH JERRY GA IC7300 N2TNQ LES NJ K3 N2DTS BRETT NJ IC705 80 METER NET 3.775 0100Z WM6P STEVE GA K3S K8NU CARL OH FTDX101D WY3T TIM FL K3S N8SBE DAVE MI K3S From don at w3fpr.com Mon Aug 23 15:25:22 2021 From: don at w3fpr.com (Don Wilhelm) Date: Mon, 23 Aug 2021 15:25:22 -0400 Subject: [Elecraft] KIO2 and KUSB for K2?

I?m installing a Zerofive flagpole antenna in my backyard. There will be several 8? ground rods at the antenna site. On one side of the house is my shack; on the other side is the home?s utility ground - a Ufer system. I?m also installing a KF7P entrance panel on the exterior wall of the shack. It?ll have several lightening arrestors and a very close-by 8? ground rod. Per N.E.C. specs, I need to tie the ground system at the shack entrance to the house utility ground - probably 150? or so from the coax entrance panel to that Ufer spot. My electrician said that a #4 solid copper wire running from the coax entrance panel to the Ufer point would suffice for keeping the grounds together. Looking at the ARRL book on grounding and bonding, it appears that what I?m going to do is to install a ?perimeter ground.? Not cheap, but the right thing to do. Anyway, the path from that coax entrance panel to the antenna is about 100?. The first 50? of it is the same path that the #4 copper wire would take. Since the ground here in SW Idaho doesn?t freeze up, I?m looking at digging a 4-6? deep trench for these wires. Is there any reason why I cannot place the coax and the #4 copper wire in the same trench? Electrical reasons? RF reasons?

For safety reasons it is advisable to separate the perimeter ground wire from any "utility" cables, including antenna cables. I would dig the trench to 12" or more, bury the ground wire, fill the trench halfway, bury the antenna cable, put a layer of some bright-colored heavy plastic over the cable (to identify it if necessary to dig it up again) and fill the rest of the trench. Put marker stakes around the perimeter. If you don't want to dig it by hand, rent a Ditch Witch. Do not forget to call Locating Services (8-1-1) to mark buried utility pipes and lines on your property before you dig - they are funded by the utilities. Stuff I learned from my colleague Tom Croda (SK) who was the national expert on communication site power and grounding. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From jim at audiosystemsgroup.com Mon Aug 23 23:27:33 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 23 Aug 2021 20:27:33 -0700 Subject: [Elecraft] Ground Wire & Coax In-Reply-To: <5097F77F-A7A1-470C-8D22-D94639B29ECF@me.com> References: <5097F77F-A7A1-470C-8D22-D94639B29ECF@me.com> Message-ID: <41c92937-c111-f74c-2cc2-f1633b3bf9c0@audiosystemsgroup.com> On 8/23/2021 6:42 PM, James Bennett via Elecraft wrote: > Per N.E.C. specs, I need to tie the ground system at the shack entrance to the house utility ground - probably 150? or so from the coax entrance panel to that Ufer spot.

There will be several 8? ground rods at the antenna site. On one side of the house is my shack; on the other side is the home?s utility ground - a Ufer system. I?m also installing a KF7P entrance panel on the exterior wall of the shack. It?ll have several lightening arrestors and a very close-by 8? ground rod. Per N.E.C. specs, I need to tie the ground system at the shack entrance to the house utility ground - probably 150? or so from the coax entrance panel to that Ufer spot. My electrician said that a #4 solid copper wire running from the coax entrance panel to the Ufer point would suffice for keeping the grounds together. Looking at the ARRL book on grounding and bonding, it appears that what I?m going to do is to install a ?perimeter ground.? Not cheap, but the right thing to do. > > Anyway, the path from that coax entrance panel to the antenna is about 100?. The first 50? of it is the same path that the #4 copper wire would take.

Recently I noticed it was making the occasional extra "click" or "thunk" upon powering up or down. Usually it would "click" when powered up and again when powered down, but recently a few seconds after the first click there would be another one, maybe more of a thunk sound. This afternoon I turned it on and when I pushed the Operate/Standby button I got a fault light and the 270V ERR message on the display. The menu HV option shows 68.4V, varying a bit, on my 240V line. I put it on the bench and opened up the top cover. There is a smell of overheated components, maybe burnt but more like too hot. I've submitted the contact form on the Elecraft support page. Any suggestions?

I keep notes from discussion of other peoples problems and their resolution. You can find all this in the archive but this is what I have in my notes for KPA 270 V problems: KPA500 270V failure: (two post by Dr. William J. Schmidt ) There are two voltage Test Points "TP" on the board under with the diodes and you need to check the voltages on those test points. Here it is. From Elecraft technical support: Nominally: TP2= RX 13.1 TX 0.8 TP4= RX 3.9 TX 13 >From Rene Morris at Elecraft (great guy!). and Thanks for the reply but in my case the problem is the voltage multiplier circuit on the power supply PCB. I just disconnected the HV (~70V) and 270V lines so they did not go anywhere and the 270V line still only measures 85V. Thanks Bruce, WB6IZG Thanks to the 2 people who replied. Thanks to Keith VE7KW who had R16 (100 Ohm) SMD resistor fail on his PS board in his KPA500. I had the same problem here. R16 tested open. It does not appear to be cracked or burnt, just a failure. R16 appears to be a resistor that feeds the voltage multiplier circuit for the 270V line. Bottom line is my KPA500 is back in service.

So with real PIN diodes, you don't have to strongly bias them off? The HV is obtained in various ways. W6JL does diode switching with a tube amp, so he has ample HV available. My K2 has a crystal oscillator feeding a toroid transformer and a voltage multiplier. Hans Summers uses a voltage doubler running off the RF output of his amplifier. I have heard discussions of people using fluorescent ballast transformers. A complication is that the voltage at a transmitter output - even though it's nominal 50 ohms - can rise quite high with high SWR, especially in the "looks like an open circuit" direction. So even though modern LDMOS PA transistors are rated to tolerate extremely high SWRs, your equipment is limited to the SWR that produces a voltage lower than the diode bias. Hans Summers' design is elegant - since he's rectifying and multiplying the RF itself, the DC is guaranteed to be higher than the RF itself. Only thing is - there is surely a delay in creating that bias. I will say that the QRP-labs approach somehow results in the cleanest, most transparent-sounding QSK I've ever heard. Better than my K2. But it's only one band, the selectivity is just ok, and it has no AGC... - Jerry KF6VB > Dave??

A PIN diode has an intrinsic (I) region between the P and N junctions.? The I region is almost completely undoped and therefore the carrier lifetimes are long relative to the frequency of the signal being switched.? A PIN diode is turned on with CURRENT bias, and as long as the signal current is less than the bias current the carriers live long enough in the I region that the signal just swishes the carriers back and forth without the diode ever becoming reverse biased ... and that holds pretty much no matter what the signal peak to peak voltage is.? You turn off a PIN by removing the bias current ... or better yet, reversing it to pull out the carriers.? The hard part of making a normal PIN diode is that you have to start with an intrinsic wafer and then diffuse first from one side and then the other side ... and while you're diffusing the second side the dopant from the first side wants to contaminate the I region.? (There are other techniques but they get even weirder). A PN diode, on the other hand, is forward biased (i.e., "on") as long as the control VOLTAGE exceeds the signal voltage.? As soon as the voltage across the diode reverses, mobile carriers are soon swept out of the junction area and the diode becomes reverse biased and shuts off.? As you say, that reverse bias could from either the control voltage OR a higher than expected signal voltage if the reverse peaks of the signal voltage exceed the control voltage. How fast all of that that happens depends upon the carrier lifetimes in the junction region and the frequency of the signal being switched.? Fast switching diodes are built with high doping levels to give a narrow junction and short carrier lifetimes, but some high voltage diodes have low doping levels, wide junctions, and therefore moderately slow carrier recombination times.? If it just happens that the carrier lifetimes are long enough compared to the signal frequency, it can work.? However, I think it's generally bad practice to use a standard diode as a PIN because unexpectedly high signal voltages can reverse bias the diode and create signal distortion ... plus the fact that diode manufacturers are NOT designing standard diodes for use as a PIN diode, and they are NOT specifically trying to control carrier lifetimes during fabrication.? A pair of high voltage switching diodes can both fully meet the data sheet specs, while one works quite a bit better than the other when used as a PIN.? That which works with today's batch might not work with tomorrow's. 73, Dave?? AB7E On 8/26/2021 3:58 PM, jerry wrote: > On 2021-08-26 15:19, David Gilbert wrote: >> Pedantic??

Upgrading is recommended in order to remain current. Release notes are listed below. They can also be found on our website, as well as directly at the radio itself in the update utility. 73, Wayne N6KR ==================== ==== RELEASE 22 ==== ==================== BUILT-IN OPERATING MANUAL UPDATED: Now at rev. C9. Among other changes, includes important note about Bose QC35 and similar headphones that are capacitively coupled. These will work with the rear-panel phones jack as-is, but for use with the front panel jack, a resistor to ground from the tip signal is needed to provide headphone insert detection. SCREEN CAPTURE IMPROVEMENT: There is no longer any need to remove and reinsert the USB flash drive after every screen shot. TX EQ NOT APPLIED IN DATA MODES. FSK/PSK MONITOR LEVEL ADJUSTABLE: FSK/PSK monitor level is now equal to the DATA monitor level, not by the CW sidetone level. It can be set separately by holding {XMTR}.MON. FSK/PSK MONITOR LEVEL VIA PADDLE VS. FSK IN: When FSK/PSK characters are sent using the keyer paddle, the FSK/PSK monitor tones will be 12 dB below the CW sidetone volume, as before. But when FSK/PSK transmit is initiated via XMIT, PTT, or a KY command, the monitor volume will be set based on the DATA monitor level (cf.dataMonLevel). VFO CURSORS TUNE SMOOTHLY ON PANADAPTER: Some users had observed jitter in the panadapter cursors while tuning the VFO. TRANSVERTER BANDS > 2.1 GHz BEHAVE CORRECTLY AT PANADAPTER: Previously, use of transverter band frequencies above 2.147 GHz would cause the panadapter to freeze. ADC OVERFLOW FALSE TRIGGERING ELIMINATED: Previously, changing preamp or attenuator settings could cause a spurious ADC overflow indication ("OVF" icon at the right end of the S-meter). PRE3 SETTING PRESERVED ACROSS POWER CYCLES. BUILT-IN OPERATING MANUAL IMAGES CORRECTED: All figures are now correctly formatted, including the illustration of the RX Dynamic Range icon (see Advanced Receive Features section). USB FLASH DRIVES WITHOUT OPERATING SYSTEM PARTITIONS: These are now handled correctly. DURING SOFTWARE UPDATE, EXT. MONITOR MIRRORS LCD. FOR SOFTWARE DEVELOPERS: Switch emulation codes (SW command) now have permanent fixed values, per rev. B12 or later of the K4 Programmer's Reference. Previously, these codes were inadvertently changed as new switch functions were added. SOFTWARE UPDATER SHOWS RELEASE PACKAGE NUMBERS: When the user selects an installation type, the associated "Rnn" release numbers appear beside each type (production, beta, etc.).
