From w6jhb at me.com Mon Feb 1 01:08:11 2021 From: w6jhb at me.com (James Bennett) Date: Sun, 31 Jan 2021 22:08:11 -0800 Subject: [Elecraft] FS: Hustler / Newtronics 5BTV Vertical Antenna + DX Eng. Tilt Plate Message-ID: One of the last items to be sold in my goal to downsize before moving out of state: a modified Hustler / Newtronics 5BTV vertical antenna. It started out as an 80-40-20-15-10 meter version. However, when I put up my Inverted L several years ago there was interaction between the 5BTV and the ?L? on 80 meters, so I removed the 80 meter parts from the vertical and added 30 meters instead, giving me 40-30-20-15-10 meter coverage. The antenna does need some TLC - using my VNA I can get it resonant on 40, 15, and 10 meters; 30 and 20 don?t cooperate and I don?t have the time to mess with it. In addition to this vertical, I have the matching DX Engineering tilt over plate, model DXE-TB-3P.to go with it. This unit alone runs $62 plus tax at DXE. I will let the vertical and the tilt plate go for $50. NO SHIPPING - you?ll need to pick up the antenna and tilt plate at my QTH in Folsom, CA - about 25 miles east of Sacramento. The antenna is currently in use, mounted in my back yard. I will take it down and have it ready for the buyer to take away. You can pay cash or PayPal. My PayPal address is W6JHB at mac.com (I have not yet changed my PayPal address to coincide with my recent change of call to K7TXA) Please contact me off-list if you are interested or have questions.

Unfortunately is a little hard to find one nowadays. And when someone offer one, ask an abusive price, $100.00!!!!! Just for the element!!! Beware of the new version HC-5.1!!!!! It?s very bad audio and output level as well. Just read some comments and reviews!

I think the fair market price varies depending on availability (no surprise with that statement!) and a fair amount of K3 are being sold versus seemingly very few K3s. All things being equal I would prefer buying a K3s as cost of upgrading the K3 aside, much of what people might want is currently unavailable from Elecraft. I think a fair price is $1200-1500. RHR had a similar-ish K3 available for $1400 last week. Now sold. Hope that helps.

Accessories sell for about 75% of new cost only when sold separately and only about 50% or less when sold with the radio because few buyers a willing to pay a high price for accessories they don't want. 73 Frank W3LPL ----- Original Message ----- From: "Larry Snyder" To: elecraft at mailman.qth.net Sent: Monday, February 1, 2021 4:22:32 PM Subject: [Elecraft] far market price I am selling my radio and curious what would be a fair market price: K3 SN 8977 ORDER NUMBER: 2381-7133-8444 DATE: April 14, 2015 K3/100-F $2399.95 1 K3 100W Xcvr.

Message-ID: A question that is likely for Eric or Wayne, perhaps Keith (or a member with a really good memory). How long does it take a K3 to activate/deactivate Split Mode and be ready to transmit? The DXLog.net developers are fine tuning the SO2V mode and from testing it appears that a delay of 200 ms is too short, 300 ms works, but may be overkill. If the value is 200 ms or less the radio drops a few dits at 36 wpm when you first transmit after a split mode change. What would be a good typical value that would always work?

The real problem with rental returns ("B Stock") is that is can no longer be sold as new resulting in a loss of value that is often more than the rental proceeds. 73, ...

In-Reply-To: References: Message-ID: I can't see this as being a good business model. A company has finite resources. If they spend time and money on a rental business, they can't spend time and money on their core business. I'd much rather see Elecraft build and ship as many K4s as possible than spend time and money on a rental business. Add to that the possible fraud (rent with a stolen credit card and abscond with the K4) and the need to fully check out the unit after rental (people buy things on ebay, claim they are broken and return a different, damaged item for a refund) they would have to charge an exorbitant amount to not lose money. If you really wanted to try one out, you could buy it, use it for a while and then offer it for sale to someone else. With the K4 in such demand, you may even be able to get more than list price for a gently used one that can be purchased today. 73, Mark W7MLG On Wed, Feb 3, 2021 at 10:46 AM Eric Garner wrote: > > isn't that why most expensive things require a deposit to rent them? > > Eric KI7LTT > > On Wed, Feb 3, 2021 at 9:32 AM Alan - G4GNX wrote: > > > I can't see that working. > > > > When a renter defaults and does a runner, Elecraft would have to layout > > a lot in recovery fees and maybe even end up with a pile of junk for > > their trouble. > > > > It might work in a very small country or if they had a physical presence > > in all states. > > > > 73, > > > > Alan.

It?s on the website. 30 days and a 10% restock fee (which may be more if you?ve bunged it up), since they?d most likely at least have to clean off your fingerprints and lord knows what else, refurbish and then resell it at a discount. And if you?ve run over it with a truck, dropped it in a river, or treated it to a dose of hamification, you?ll get your junked radio back instead of a refund. PS ? it doesn?t apply to kits that have been partially or entirely built. If you buy one and don?t like it, it should be pretty easy to find potential buyers willing to throw money in your direction ?

In-Reply-To: References: Message-ID: I think Elecraft has enough on its hands with COVID 19 just getting these rigs designed, updated, built and shipped. I am not aware that any major manufacturer of HF amateur radio transceivers maintains an equipment rental program. A rental program would be complex to administer. You would have to deal with insurance, shipping concerns and complaints that inevitably are part of such a program. Plus a legal team on hand to deal with problems that result from a rental experience gone bad. The program would have significant staffing requirements. I would think even if they were interested in offering this service, they have many more pressing concerns giving COVID 19. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Eric Garner Sent: Wednesday, February 3, 2021 9:45 AM To: Elecraft list Subject: Re: [Elecraft] Can I rent a K4? isn't that why most expensive things require a deposit to rent them?

I can't see there being any way Elecraft could justify the risk and hassle of renting out their equipment.? Ask yourself this ... do you think you could make money buying a K4 and then renting it to other random hams you don't know?? Would you be willing to take that kind of risk?? Think of the time it would take on your part to administer it. I suppose, given the purported remote capability of the K4 using a free app (as opposed to a piece of dedicated hardware), somebody might be willing to offer remote access to a K4 in exchange for a modest fee.? In my opinion, if the K4 is as remotable as claimed then it should be mostly possible to evaluate it that way. ? Even then I suspect that Elecraft wouldn't want the hassle of offering that ... maybe somebody else would. Dave??

Having worked in selling high value pro audio products, I can confirm that Joe is absolutely right. And Elecraft is a small company, has a backlog of orders that, thanks to their reputation, the effect of COVID on their workers, and their supply chain, they are taking much longer than expected to fulfill. Eric and Wayne are smart businessmen. Why would they do something that loses money? 73, JimK9YC From wunder at wunderwood.org Wed Feb 3 15:05:28 2021 From: wunder at wunderwood.org (Walter Underwood) Date: Wed, 3 Feb 2021 12:05:28 -0800 Subject: [Elecraft] Can I rent a K4?

Set up a rig rental business that isn?t limited to Elecraft. There is no reason that this has to be an Elecraft operation. A larger business might balance sales profit vs rental profit and self-insure (think car leasing), but that isn?t necessary. This would be like Hertz or Avis. Buy the rigs, rent them.

All three antennas are selected by the KAT500. I also have a second radio, an older Yaesu FT-101ZD. This rig can be switched into the lineup in place of the K3S. I sometimes enjoy using the older rig. In this manner the FT101ZD output goes through the KPA, then the KAT. I find the KAT plays well, a little tap of the key will cause it to auto-tune. I'd like to be able to use the KPA500 as an amplifier, but so far it won't key. I've tried the RCA Phono plug into the PA Key jack, but as long as the K3S is connected the KPA won't go into TX without the proper software signal. I did try with the software keyline interrupter a few months ago, but that prevented the K3S from switching the amp unless I also used a Y-connecter and phono cord from the K3S for amp keying. When I did the keying didn't seem as crisp, though. The K-Line is all connected as in the diagram on page 5 of the KAT500 manual. Ideally, I could turn off the K3S, switch the feedline from the K3S to the 101ZD, and have use of both the tuner and amp. Is there an easy way to do this? Perhaps one of those breakout boxes?

Which it rarely (never?) is with a real human voice. Aside from the legal (and oft disputed) aspects of AM power limits, you?re better off being conservative and setting drive levels for something under 375W carrier from the amp. Maybe 250-300W. That will ensure you have some headroom for voice peaks (especially if you have a good bit of positive voice asymmetry), keep the amp cooler, etc. And no one on the receiving end will know the difference, anyway. The referenced article is a good place to start. A monitor scope on the output is essential ?

An SB-610 or equivalent is hardly a precision instrument, but more than adequate. The point of the scope is primarily to observe and prevent negative peak clipping, ensure you?re not out of headroom and starting to flattop on positive peaks, and adjust mic gain for something approaching 100% modulation.

I just finished some more testing and found that when I remove the AUX cable from the back of the KPA and try to put the KPA into TX with the keyline, it stays in RX. A continuity tester confirms the rig keyline is closing when the rig is in TX, and the KPA shows driver power output, as does the KAT. But, the KPA won't switch to TX and amplify.

It has an excellent discussion about using the KPA500 with two radios (but not at the same time?). The RF paths need to be switched with a good RF switch, making sure that very little signal from the transmitter gets through to the *other* transceiver?s receiver. Depending on the radios, it is possible for an Elecraft radio to use the PTT line in the AUX I/O connection, and the other radio to use the RCA jack PTT. You have to be very careful with this, however. Modern radios output a 0 - 5 volt signal on their Key output, grounding the output for transmit. This is exactly what the KPA500 is looking for, although the non-transmit level can simply float (all Open-Collector). It is the ground to transmit that is important. Older radios may have a signal that far exceeds these levels, for example the old tube-type radios using grid-block keying may put a large negative voltage on the PTT output. This will not do well in the KPA500 circuitry. In this case the radio should drive a relay that keys the amplifier. So, yes it is quite possible to have the KPA500 driven from more than one radio through a selector switch. You just have to do it right. A copy of Fred?s book can show you the way. 73!

I took a step back and realized I am spoiled by the close integration of the K-Line. The reason the FT101 can't key the amp is because, unless the K3S is turned on, the amp won't leave STANDBY mode. Even with the AUX cable disconnected, the amp sits in STANDBY and pushing the OPER-STBY button doesn't do anything. I guessed a menu setting might control this, and setting the KPA Menu item RADIO to ANALOG now allows me to switch bands and from STANDBY to OPERATE via the KPA front panel buttons with the K3S turned off. A quick test shows 25 watts of tube-generated CW gives 450 watts output. Looks like I'm in business. Just need to change the menu item when I switch radios.

"The DDU is what the display on my KPA500 should be. It sits under a computer monitor where it effectively displays the current telemetry of the amp. It is a great accessory that keeps me from having to reach over and press buttons on the amp to see what is going on. The DDU makes for more effective operations." "Recently stumbled upon this item. It sounded just like what I wanted. It eliminates having to press the various buttons on the KPA500 to see the different readings. With this little box everything you need to know is right there at one time. It's bright and easily readable, yet it's small and takes up very little room. Keith sent it within two days and I had it unboxed, connected and working in about 20 minutes. This is definitely one of the more useful side items I'll be using in the shack."

Chuck?s description with the K3S Not connected to the KPA are correct. When nothing is connected to the band lines, they are pulled high inside the KPA500. In the two radio modes that rely on BAND inputs, this would be an invalid band (1111) and not allow the amplifier to go into OPER mode. Chuck is correct here in that switching to either analog or serial mode will allow the operation he desires. But, there is another choice. When the KPA500 is in one of the BCD modes (RADIO = K3 or BCD), and the band signals indicate a valid band, then the KPA will go into OPER mode and should work properly. Now, how can this happen with a K3 or K3S attached? The K3/K3S has resistive pull-ups on the band signals, so the signals are pulled up to Vcc when they are not driven to ground. Vcc is the 5V regulated power bus in the transceiver when it is powered. But when the K3/K3S is powered off, the 5V rail will sink to the 0V level as the capacitors bleed off. That means that the band signals are actually pulled to 0V (ground) a short time after the K3/K3S is powered off. This combination defines a valid band, and if the KPA is set to K3 or BCD modes, the amplifier will actually switch to the 60 meter band. It will also go into OPER mode if you tap the OP button. So, the alternative solution is to leave the K3S attached, power it off, wait until the KPA500 switches to 60 meters, then you can switch the KPA into OPER mode, switch the input to the alternate rig, and start operating. 73!

I guessed a menu setting might control this, and setting the KPA Menu item RADIO to ANALOG now allows me to switch bands and from STANDBY to OPERATE via the KPA front panel buttons with the K3S turned off. > > A quick test shows 25 watts of tube-generated CW gives 450 watts output.

Several of you have written, some with helpful suggestions, but many being curious about what I thought was ?suspicious? about the KAT500 transaction. Briefly, I have learned when you place a ?WTB:? ad on QTH.com, you often encounter one of the lurking scammers, who will offer to sell you the item you are wanting. They will spoof an unsuspecting, legitimate ham, who does not include an email address in their QRZ listing. There are several tell-tale signs of such an operation, and such was the case yesterday with the offer to sell me KAT500, SN 0296. I wrote this group yesterday, hoping that perhaps the rightful owner would step forward. Sure enough, last evening the real owner of the equipment contacted me. Interestingly, asking for a close-up photo clearly showing the Serial Number will usually stop these guys in their tracks, but yesterday the scammer provided me with that photo. These guys are becoming very sophisticated. Anyway, thanks for bearing with me while I outed this scammer. 73 es Stay Safe, Jim ? WS6X P.S. I?m still looking for a KAT500. Any offers? ?

No rigs at the time would function efficiently with on/off keying at that speed, so we were experimenting with 300 WPM CW sent using the normal RTTY method of 170Hz shift FSK. It worked like a charm and our CW reader would copy perfectly at that speed too. Just about everyone in the company was a ham from the pres. on down, so we played around with it on 2 meter FM using AFSK tones into the mike jack until something new came along.

Bird slugs have a tolerance of 5% of full scale, and the reading is only valid into a 50 ohm resistive load. The LP100A is 5% of the reading at any power level and into complex loads (i.e, not only 50 ohms resistive). Years ago, Electraft used an LP100A for final test of their rigs. Don't know if they still do. About five years ago, I bought W6OSP's LP100A from his estate and added a second coupler for my SO2R station, and had both calibrated at his factory. It auto-switches with signal from the amplifiers for the two radios. 73, Jim K9YC From d.cutter at ntlworld.com Sat Feb 6 16:05:44 2021 From: d.cutter at ntlworld.com (CUTTER DAVID) Date: Sat, 6 Feb 2021 21:05:44 +0000 (GMT) Subject: [Elecraft] K3 - Maximum CW speed from manual key In-Reply-To: References: Message-ID: <1749834568.1232968.1612645544587@mail2.virginmedia.com> From wes_n7ws at triconet.org Sat Feb 6 17:37:53 2021 From: wes_n7ws at triconet.org (Wes) Date: Sat, 6 Feb 2021 15:37:53 -0700 Subject: [Elecraft] K3 - Maximum CW speed from manual key In-Reply-To: References: Message-ID: <053cea30-8261-16ac-f302-23b8d8ab668e@triconet.org> I've heard rumors of that but I have 38 states confirmed on two-meters (from the depths of southern AZ), mostly on ear-copy MS.?

I checked The Bird 43 with two other Bird 2500w slugs from friends and they were all reading the same with a dummy load at 1500w.? I did the KPA1500 calibration using the Bird with a high power dummy load, then checked again with my antennas in band segments where they present no significant reflected power and near 1:1 SWR.?

When nothing is connected to the band lines, they are pulled high inside the KPA500. In the two radio modes that rely on BAND inputs, this would be an invalid band (1111) and not allow the amplifier to go into OPER mode. Chuck is correct here in that switching to either analog or serial mode will allow the operation he desires. > > But, there is another choice. When the KPA500 is in one of the BCD modes (RADIO = K3 or BCD), and the band signals indicate a valid band, then the KPA will go into OPER mode and should work properly. > Now, how can this happen with a K3 or K3S attached? The K3/K3S has resistive pull-ups on the band signals, so the signals are pulled up to Vcc when they are not driven to ground. Vcc is the 5V regulated power bus in the transceiver when it is powered. But when the K3/K3S is powered off, the 5V rail will sink to the 0V level as the capacitors bleed off. That means that the band signals are actually pulled to 0V (ground) a short time after the K3/K3S is powered off. This combination defines a valid band, and if the KPA is set to K3 or BCD modes, the amplifier will actually switch to the 60 meter band. It will also go into OPER mode if you tap the OP button. > > So, the alternative solution is to leave the K3S attached, power it off, wait until the KPA500 switches to 60 meters, then you can switch the KPA into OPER mode, switch the input to the alternate rig, and start operating. > > 73! > Jack, W6FB > > >> On Feb 5, 2021, at 5:12 AM, Chuck Chandler > wrote: >> >> OK, I've figured out the problem.

Per the normal definition of a Morse "word" being the word "paris", 300 wpm means each dit would be no longer than 4 msec. As best I can recall, the rise and fall of the K3 keying waveform are each around 2.5 msec.

Using more slugs does help things, but to be really sure, test equipment needs to be periodically calibrated, which Hams never do. Dummy loads should be measured with a VNA. So, what you did is a big help, but still can't provide 100% assurance that it is accurate. I understand that is the best most Hams can do and probably better than most. An LP-100A does come with a NIST traceable calibration from the factory and it can be recalibrated, again something Hams never do. I have one fancy scope / spectrum analyzer that I do get calibrated yearly and I use that for a reference. I have a VNA with a set of calibration standards and use that to measure attenuators / taps that I put between my transmitter and the analyzer. I admit I do not calibrate anything else, but I use the calibrated stuff as transfer standards. I also have a couple GPSDOs as frequency standards to compare to. 73, Mark W7MLG On Sat, Feb 6, 2021 at 4:55 PM Jim McCook wrote: > > Good points, Ray and Jim, I should have been more detailed with what I > posted.

References: <000301d6fdb0$ff47b810$fdd72830$.ref@yahoo.com> Message-ID: <000301d6fdb0$ff47b810$fdd72830$@yahoo.com> When I received my KPA-1500, I noticed I had to drive the LEDS into the "red" zone to indicate 1500 Watts into my Bird 43 wattmeter with a 2500W slug, and Palstar DL2K dummy load. There also was a comprehensive part of the KPA-1500 manual that details how to readjust the power indicating LED's, so I was wondering - what gives? The Bird 43 specs have a tolerance of 5% of full scale, which for a 2500 watt slug is 125 watts. I asked Wayne (or was it Eric?) at a show as to what was used by Elecraft to calibrate the amp's power meter and was told they used the LP-100A. So, that is the standard that was used in the Calibration of the KPA-1500's.

The meter itself can be off too. Using more slugs does help things, but to be really sure, test equipment needs to be periodically calibrated, which Hams never do. Dummy loads should be measured with a VNA. So, what you did is a big help, but still can't provide 100% assurance that it is accurate. I understand that is the best most Hams can do and probably better than most. An LP-100A does come with a NIST traceable calibration from the factory and it can be recalibrated, again something Hams never do. I have one fancy scope / spectrum analyzer that I do get calibrated yearly and I use that for a reference. I have a VNA with a set of calibration standards and use that to measure attenuators / taps that I put between my transmitter and the analyzer. I admit I do not calibrate anything else, but I use the calibrated stuff as transfer standards. I also have a couple GPSDOs as frequency standards to compare to. 73, Mark W7MLG On Sat, Feb 6, 2021 at 4:55 PM Jim McCook wrote: > > Good points, Ray and Jim, I should have been more detailed with what I > posted.

I can tell GQRX to go lower but it then detects nothing anymore... GQRX is a Linux SDR program where a funcion that says "No limits" allows to tune higher and lower than these two frequency limits. I suppose you more likely need an attenuator between the upmixer and the dongle. 73, Peter PA0PJE Op 08-02-2021 om 14:48 schreef Eric Lanzl: > Regarding the RTL SDR dongle.

The tuner chip does have a sort of "bypass" mode that lets you see the very low frequency signals that are below what is considered the normal tuning range. It comes at a price. If you are really interested in the lower frequencies the use of an external up converter would be a good idea. -- Cheers!

The LCD sits too high and the pins sit just above the top solder pads. They don't go into the holes at all. Yes I can solder from the top but this will make a poor solder connection. Also the reflector is loose and moves around the backlight lens does not pinch it against the PC board.

I reported one issue where the P3 would return to an entirely different band than the one commanded. The head of FW for Elecraft confirmed this is a bug that needs fixing. When that will happen, if ever, is anyone's guess with the K4, pandemic, etc. In macros I write to change bands and frequency, I find that I must issue P3 commands twice to have the P3 properly centered as I want it. I issue the first set of P3 commands at the beginning of the macro string, and the second one near the end.

I have 2 of the rtl-sdr dongles sitting in front of me. The earliest ones received 27mhz thru appx 1700 mhz. There is no front end to speak of, and they are prone to overload. To receive below 27 mhz required a hardware mod that many times would destroy the device unless you are skilled with soldering smt devices. Also the software (rtl_fm) wasn't capable of using the bypass - it needed to be modified. some of the newer software did work OK. As an HF receiver, it was a horrible solution. The folks at rtl-sdr.com realized this and a few years ago put out a new version known as the V3 model. The marking on the device is "RTL2832U R820T2 TCXO+BIAS T+ HF". It is the same size and comes in a shiny (sort of) aluminum case is is today about $25 on Amazon etc. The V3 model does receive on HF down to a few 100 khz since the bypass parts are already installed. Many of the newer sdr programs know to use the Q mode receive and tuner bypass options to receive in the HF region. With gqrx, as mentioned before, there is a no limits checkbox that needs to be checked for the software to work below 27 mhz. I've been using one of these for a couple of years and it works, but not that well. Without an AM band notch filter the am broadcast stations wreck hf band reception. A decent one is about $10. Next, there are image issues across the hf band, greater when above about 14 mhz. The sensitivity is not good and, again, they are prone to overload. I tried it connected to the IF out of my K3 and would not do it again. As was suggested, the sdr SdrPlay rsp1 receiver is about $100 (there are newer and better sdrPlay units) works and doesn't require the am notch filter. (Aside - you may not require the notch filter when coming out of the IF port of the K3 - I didn't try). There are newer dongles from other suppliers that do not cover HF by default and may or may not work in HF. I think almost all require an upconverter (another $45 to $75) to be useable. But now you have 3 devices (am filter, converter, rtl dongle) on your desk. The rtl-sdr dongles are a good solution for those just learning what radio is and want to play without spending much more than dinner money, but if you can afford a K3 you can do better than using an rtl dongle for a panadapter display. > Using an sdrPlay rsp1 works (somewhat) when used with the right software, and may be an option for you.

Then the P3 frequency range will not change even if the K3 VFO frequency is out of range. It may be that some logging programs do not retain the old frequency upon a band change.? Even if the frequency is "wrong" only for an instant, that would be enough to confuse the P3 if not in "Static" mode. It would be interesting to see what N1MM and other logging programs are sending to the P3/K3 on band changes.? There is a little-known serial debug monitor in the P3 that shows the traffic on the two RS-232 ports.? You activate the function by simultaneously holding the DISPLAY/AVERAGE and FN1/FN5 buttons.? The P3 screen changes to show RS-232 traffic color-coded to show on which port and in which direction the traffic is going. The data can fly by awfully fast when using a logging program.? You can freeze the screen immediately after a band change by tapping the FN2 key.? Tap it again to unfreeze the screen.? If you want to show more data you can choose a smaller font size with the MENU > Font feature. I'm pretty sure that feature still exists in current P3 code.? I can't check this myself since all my ham equipment was recently lost in a fire.

Before, the difference was very small, just few Hz, but now I tune RIT up to .25 - .30 kHz and it's not getting any better.

For example changing bands, if the center frequency was previously tuned to 10.000.00 MHz with a span of 20KHz, then changing to another band, say 20M or 40M, then back to 30M (10MHz), the center frequency will briefly appear in the upper left corner of the P3 display, as well as in the center of the display. It then corrects, with the proper LH-CENTER-RH ( 9.990.00 ? 10.000.00 ? 10.010.00 ) displayed. Occasionally the display will show ( 10.000.00 ? 10.000.00 ? 10.010.00 ) and not correct the display. Also the FILTER BAND PASS will appear on the left side of the display, remaining there. All of the communication to the P3 in this case is from the K3S. I have no computer or other device connected to the K3S/P3. Initiating a ?CENTER? command via the P3 ?BUTTON? will usually correct the issue??

If the KAF2 or KDSP2 is installed, reseat those options to wipe away any oxidation on the pins. When the loss of AF appears, do you still have sidetone (use the SPOT button in CW mode)? If so, the AF amp is OK - follow the path from the IF amplifier output on the schematic and reflow the soldering on all components in that path. 73, Don W3FPR On 2/9/2021 8:19 AM, Rune Edberg via Elecraft wrote: > Using a second-hand Elecraft K2, QRP rig.

Maybe it's time for an inflection point and relocate out of CA. Here in Utah except for masks and the customer density at restaurants I can't even tell there is a pandemic. It's nearly impossible to find a parking spot at the mall. We have the sixth lowest death rate, and the 4th highest infection rate per 1M in the nation. I'm guessing that we are getting close to herd immunity.

In-Reply-To: References: Message-ID: I just saw this and below is a copy of what I posted to his comments section. "Hi Mike, While the last year has been challenging due to the Covid crisis, the CA wildfires near us and related supply issues, we are not now shut down by CA for COVID and are financially healthy. We are alive and kicking - shipping radios, amplifiers and accessories every week. You mentioned the backlog on the KX2, KX3, KXPA100 and K2, for which I apologize. All of these are still in production and shipping. Orders for all of our products surprisingly have been much higher than we expected during the Covid crisis, which has contributed to the current backlog on these products. (It looks like hams had more time this past year to enjoy the hobby, which has helped sales!) I just checked our shipping report for the first ten days of this month (through today 2/10) and all of these are shipping along with their accessories, the KPA500, KPA1500 etc. We certainly have seen intermittent production delays due to parts shortages, but to date nothing has shut us down. We've gotten pretty good at quickly finding alternate parts when one is delayed. I see you were disappointed the K3S was no longer in production. We formally discontinued it May of 2019 when we introduced the K4, after a close to 13 year run for the K3 and K3S. We've also previously discontinued the K1 and KX1, which also had a long run. In general we discontinue products as sales decrease over time and when new products replace them. Fortunately we've been able to continue production of the K2 since its first ship in Jan of 1999. Now that's a long run :-) We are also ramping up production and shipments of the K4, which also competes for production resources. I noted in my recent live video Q&A session on the K4 that we had just received 100 full PC board sets for the K4 from our local assembly subcontractor and these are winding their way through production. (See the Elecraft YouTube channel for the Zoom recording.) We received a huge response to the K4 and as a result have a very large number of backorders that will keep us busy and financially healthy for some time. Lastly you mentioned the 'TBD' on K3S option boards and accessories. We recently asked for interest from our customers on a special run of all of these and received a very large response, which makes it economical to build another run of most of these. We've now received the quote updates from our suppliers and we will be contacting everyone starting next week who expressed interest in these items. We're still in business, healthy and enjoying designing and building exciting products for the amateur radio community, and we hope to continue doing so for some time!" 73, Eric - WA6HHQ *elecraft.com * On Wed, Feb 10, 2021 at 6:24 AM Dave Cole wrote: > https://www.amateurradio.com/what-has-happened-to-elecraft/ > -- > 73, and thanks, > Dave (NK7Z) > https://www.nk7z.net > > ______________________________________________________________ > 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 eric.swartz at elecraft.com > From n7krt_1 at yahoo.com Wed Feb 10 15:48:52 2021 From: n7krt_1 at yahoo.com (jeff martin) Date: Wed, 10 Feb 2021 20:48:52 +0000 (UTC) Subject: [Elecraft] K3 for sale References: <631009535.307662.1612990132654.ref@mail.yahoo.com> Message-ID: <631009535.307662.1612990132654@mail.yahoo.com> I have my K3 for sale.

They are built for the semi-pro audio world, typically people with small home studios. Being a quasi consumer/semi-pro product, new models are introduced periodically to keep up with new technology, but anything from mine, the US100, is perfectly suited for digital modes. I've used that US100 in my station for all digital modes for many years, and several years ago bought one used to have as a spare. Yes, newer models have greater bit depth and faster sampling rates, but in ham radio, our only use for these properties is for devices like N8LP's spectrum display. 73, Jim K9YC From w1rc at near-fest.com Thu Feb 11 10:32:33 2021 From: w1rc at near-fest.com (Mister Mike) Date: Thu, 11 Feb 2021 10:32:33 -0500 Subject: [Elecraft] [ELECRAFT LIST] Using Vintage Collins 30L-1 Linear Amplifier with K2 and/or K3.

It is easy to create one, using the 8R line to operate a transistor switch. Such a circuit is shown here and there are others. However, most are designed for a positive keying voltage, not a negative one. You would have to modify it if you want to key -15v. The 100-watt K2 /does/ have an amp key output. But it is also designed for positive voltages. The K3 and K3S also have amp key circuits. Although they can handle relatively high voltages and currents, they must be positive. Many "soft-key" circuits do provide a positive keying voltage. Are you sure yours doesn't? +15v at 1 ma would be easy for either the 100-watt K2 or the K3/K3S to handle. Check it with your DVM. 73, Victor, 4X6GP Rehovot, Israel CWops #5 Formerly K2VCO https://www.qsl.net/k2vco/ On 11/02/2021 17:32, Mister Mike wrote: > I have a Collins Radio 30L-1 Linear Amplifier.

It's a great way to communicate and have fun! You are going to receive many different answers, and all of them will probably be correct. As it's a personal preference as to how one likes their rig set up for CW reception. Some 40+ years ago, I loved my sidetone set at 650Hz, but now 420Hz is the ideal sweet sound to my ears. Yours will differ, experiment. In my K3s, I have in both the main and sub receiver, filtering of 2.8, 2.1, 1.0, 400, & 250. Lots of folks will say I wasted money on the filters, as some of them are very close in response, but again, my preference. When I am on the radio in the CWT's, I have my filtering set for 400Hz, and then use my "wet" filter (ears & brain) to filter beyond that. I will drop down to 250Hz if someone gets a little close to me. When I am in S & P mode, I might get down to 100Hz filtering to help zero in on a station, especially if it's weak, again my preference. I keep saying "my preference" because today, that's the way I like it, next year, good Lord willing, it might be something different. The best advice I can offer is to experiment with the radio and see what works best for you. That can change on a day-to-day basis depending on conditions. So, you have to be dynamic on your settings and never believe it's set in stone. A good read is Fred Cady's - KE7X, now a SK, book on the K3/K3s radio and how to use it. It has many good pointers and lots of valuable information. I believe PDF formats are still available on LuLu publishing. I hope that helps a little. 73 de Jim - KE8G On Thu, Feb 11, 2021 at 5:25 PM MaverickNH wrote: > Apologies, as I'm sure this has been addressed before.

Those are roofing filters, designed to protect the MAIN IF filters from VERY strong stations close to your frequency. Those main IF filters not hardware filters, they are implemented in DSP, and are what vary when you adjust the Width/Center (for CW, RTTY) or Low-High knobs (for SSB, Digital). The 1kHz filter is the only one I'd call wasted. The 2.8 filter is a great TX filter, because it's a lot flatter than the default 2.7 kHz filter. The 2.1 filter helps a lot with SSB in a contest; my ear/brain thinks 1.8 kHz is too narrow. The 400 Hz filter is good for RTTY and CW, and the 250 Hz filter helps with VERY strong CW signals in contests. But in each case, they ADD to the primary filters in the DSP IF. When two filters of approximately the same bandwidth are both in the signal chain, they response "cascade," meaning that the two in combination have skirts that fall off much faster than only one of them, so their rejection of off-frequency signals is much greater. 73, Jim K9YC From jh3sif at sumaq.jp Fri Feb 12 02:22:16 2021 From: jh3sif at sumaq.jp (Keith Onishi) Date: Fri, 12 Feb 2021 16:22:16 +0900 Subject: [Elecraft] K3S CW Optimization In-Reply-To: <1613085851853-0.post@n2.nabble.com> References: <1613085851853-0.post@n2.nabble.com> Message-ID: K3s provides many parameters to make your K3s with best setup for CW operation such as Pitch, AGC, APF and Dual-Passband CW Filtering, Receive Audio Equalization, etc. Also you may adjust SHIFT, WIDTH, LO/HI Cut in DSP Filtering.

I have been a CW ham op for 67 years with some maritime CW ops also. In the old days we needed to use our brain filters, since any receiver we could afford was wide as a barn door, and even the more expensive ones had filtering far inferior to what we now have. So for casual operation many of us old guys actually prefer a wider bandwidth for tuning around and even a QSO with no or even some nearby stations, and may only use the very narrow roofing and/or DSP filters in our rigs if the going gets really bad. I believe newer hams probably rely more on a narrow filter (DSP or roofing). When I ordered my K3S a few years ago I got only the 2700, 750, and 400 Hz filters. I ordered the 750 Hz filter directly from Inrad. My plan was to later Order more filters, but the DSP filter is so good that I do not think I will order the 250 Hz filter. In other radios I usually used around 700 Hz to 1000 Hz filters for casual CW, but really needed good 400 Hz and 250 Hz filters for tough (contest) operation. So with The DSP filtering, I think your 500 Hz filtering should be adequate for most or all of your operating. The exception is if you Use your rig in close proximity to other stations (like FD) or a KW within a few blocks, or if you have a very large Yagi in say a 20 meter contest loaded with other well equipped stations. As Jim stated his 1000 Hz filter was probably not needed, just use your SSB filter with your DSP set to 1000 Hz or whatever, and if things get really tough narrow the DSP filter all the way down to 500 Hz or less and your roofing filter will switch in. I do often use my 750 Hz filter, but not sure it would be worth it if I ordered again. Also, sometimes the NR function is a real help, but usually it does a better job with somewhat wider filtering, perhaps even over 1000 Hz in some situations. If budget is not a consideration, and you like go for serious contesting, and sometimes DX, then a filter less than your 500 Hz filter may be worthwhile, so spend some time on CW. As to the set up as Jim suggested get and read the Fred Caddy book. Good info on setting up where the switch in point for various roofing filters may be different than the BW setting (I set mine up slightly different than the Elecraft suggestion). Also Fred?s, and Elecraft books offer some good advise on how to best use NR, NB, and APF and other buttons. The threshold settings are important, and the settings for signals down in the noise on 160 may not be the same as for typical ham operation. Enjoy your K3S, I sure enjoy mine, and do experiment since some CW folks use AGC and others ride the RF gain control. I am sure many will have other equally good or better suggestions, so just experiment awhile before you order more roofing filters.

How do I get it to stay in By-Pass Mode." One reason for flashing MAN is that KAT500 has entered auto tune mode and is waiting for sufficient power to start the solution search. I don't know if this is the reason in your case. Do you have the ability to log the commands your Flex is sending to KAT500? Is it possible your Flex commanded autotune (FT;)? I never run my KAT500 in BYP mode after I found defects in the antenna selection logic when BYP mode is active. I always run in MAN mode and MAN mode with bypass active is electrically identical to BYP mode as far as the tuning solution is concerned.

No receive and high swr. PA and ATU on ANT2 are working as expected and the relays is switching between the 2 antennas. I think I?ve fried something on the input of ANT1.

It turned out to be the same issue as you experienced. After removing the ANT1 SO239 connection from the ATU board I?ve measured also a shorted cable. To be sure that there are no other issues, I connected the ANT2 SO239 to ANT1 on the ATU board and voila, ANT1 it is working!

All rigs are "noisy" if you run the RF gain full bore. Experiment with backing off the RF gain and increasing the AF gain (if needed) until a good signal-to-noise ratio is attained by your ears.? This applies to both CW and SSB. It will also be helpful if you put the AGC in "fast" mode. Finally, ignore the S-meter.? It will only confuse you and is needed only when comparing two or more incoming signals.? It has nothing to do with optimizing reception. 73, Kent?

In the meantime, the encoders for VFO A and VFO B are the same - so he should swap them to see if the problem follows the encoder. If it does, then a new encoder will fix it. If not, it is more involved and will require additional assistance from Elecraft support. If he does not know how to remove the Front Panel assembly and swap the encoders, he should download the assembly manual to see how it goes together and then reverse the procedure. 73, Don W3FPR On 2/17/2021 4:08 PM, Hank Garretson wrote: > My buddy Kurt, W6PH, who is not on the list, has a K3S.

When, (not if), the shipper drops your K3 to the ground from 4 or 5 feet up, and the rig stops with a 20G or 30G, (or more), pulse at end to motion, the weighted knob then becomes a rather good looking hammer hitting the encoder shaft...

However, a few minutes ago I noticed I was getting about half the output power on 20 meters that I typically get with around 30 watts drive (about 600w vs 1200w). PA current is less than normal, around 30a. Similar problem on the higher bands, I can no longer get 1000w. On 40m I can, but it requires more drive. Seems like something died in the amp; I'm not familiar with the design, but perhaps an output module. No errors or ill behavior from the amp other than the loss of power. I will contact Elecraft support unless there is something I'm missing here. I just looked in the archive and see that this has happened to others.... I use the amp remotely so I guess I'll have to take it home with me.

After two weeks a new sunspot has appeared.? We are also in a stream of solar wind.? Our ionosphere is being refreshed.? The auroral oval is strong at the moment.? Hopefully things will settle down a bit for tomorrow.? Noise levels are still fairly low maybe the signals will pop out.? I expect both bands to change during the nets due to the time of year.? Twenty meters has been getting longer but I'm reaching different parts of the US. ?? By the time the snow stopped falling I had about a foot.? Even with the rain there is still a three to four inch covering.? One morning I turned the faucet only to hear a gurgle.? I slogged through the sloppy snow to the pump house only to find the relay stuck on.? OK, a reset.? But that didn't work.? Neither did my confused glare.? So I shut off the power to the pump and did other chores.? A few hours later I turned the breaker back on and reset the relay.? A few iterations of that and now the water is running.? For some reason it thought the well had run dry in the rainy season.? Maybe the confused glare helped. Please join us tomorrow on: 14050 kHz at 2200z Sunday?

Message-ID: All: I noticed that he AGC-F setting on my K3S seems to have no effect when in CW mode yet it works in SSB mode. When switching between AGC-F and AGC-S the decay is slow so it appears to be "stuck" in the AGC-S setting when in CW mode. The AGC settings are: AGC DCY = SOFT AGC HLD = 0 AGC PLS = NOR AGC SLP = 10 AGC THR = 10 AGC-F = 130 AGC-S = 8 The rig (SN 11829) was factory assembled. Any ideas?

Solid state amps are not any more complicated than tube amps, and I think easier (and safer!) than tubes. My early KPA1500 (#76) has been great, but not having the schematics really bugs me. I know everyone at Space Galactic Headquarters is busy with the K4 but posting the KPA1500 schematics would not take more than a few minutes. And my amp is way out of warranty so they aren?t risking anything. Internally it looks like a pretty generic design.

Here's my comparison of the two since I own both. The KPA1500 fan noise is better to my ears sitting on the desk 4 feet from my operating position that the PG-XL. I use the 1500 at home while the PG-XL due to its LAN integration to the Flex radio is at the remote site 20 miles away. Both are great amps and with the last updates done to my KPA1500 a little over a year ago it has been trouble free.

Another choice might be something called REW (Room EQ Wizard) which is an AMAZING, free program that is Java based, so it should work across different platforms.? There is a Mac dedicated version,? but I know little about Macs,? whether yours might be compatable or not. It is a very capable and complex program,? originally designed for EQ'ing speakers and subwoofers with your room, for good, balanced bass. It of course, has a very capable audio measurement and spectral display capability,? with a whole lot more.? The designer has been adding things as he's been working on it for a long time now, it has a pretty amazing list of features, especially for a free SW. Beautiful and flexible graphing, I might add. Check it out,? help files are pretty good.? Might be a little daunting, but you won't be needing to deal with some other things that would be part of a usual setup. ? You don't have to do any mic setup and cal, of course,? since you're not measuring room responses,? and it's pretty basic to just get your rig speaker output into a computer line input,? to measure response like with Spectrogram.? Of course, you could use the built in signal generator to put pink noise into your mic input to measure your TX response, as a more advanced usage, later perhaps.... https://www.roomeqwizard.com/? is the site.? There is a pretty active forum on a site called AV Nirvana, used to be you had to make an account there to download REW,? but he now has the stand alone site.?

Are you planning on relegating CW/SSB/etc. to a "nice-to-have" usability-wise, or are you trying to keep those usable while making digital modes more intuitive and straightforward? I would want both the latters in a product I'd buy. I'd love to see a hybrid UI like the KX3 + PX3, but with a drastically more sophisticated UI on the panadapter side. I don't want my radio and computer in the same box, but I'd *love* a compact, purpose-built computer for digital modes, logging, and so on. (I'd generally caution you against buying or making all-in-one devices, since if one part breaks, you've gotta send the entire thing in for service.) Really, if you're okay with a KX2 or KX3 hanging off the side, you could do most of this with a RPi (or your favorite single-board computer) and a 7" or 10" display and a few adapters for audio and radio control and a bunch of software work. I don't think it's realistic for Elecraft to cram every new digital mode into the firmware for every rig they've ever made (although I would be more than happy to provide a wishlist!), but something like this could be a good compromise between "your choice of RTTY, PSK31, or PSK63" and "schlep an entire laptop and a bunch of wires.

FWIW, we?re already seeing the integration of FT8 into amateur radio equipment. However, it isn?t hardware but software that does this as exemplified by SmartSDR for iOS and SmartSDR for Mac developed by Marcus, DL8MRE and is available through the appropriate Apple App Store (iOS and MacOS). Within the software configured to manage Flex-6000 series transceivers, FT8 is a ?mode? that allows the operator to use their Flex-6000 product locally or remotely with FT8 integrated into SmartSDR on their device. This capability is not available through SmartSDR for Windows (developed by FlexRadio), but as an Apple user I?m thrilled with the integration that is now possible with an iPhone, iPad, or Apple Mac/Macbook using MacOS. It can?t get any simpler to integrate FT8 into an amateur radio station. I have to presume that as Elecraft evolves the K4 ?ecosystem? to include remote operation that similar integration is feasible. Whether Elecraft will do this or by third party developers remains to be seen. 73, Barry Baines, WD4ASW/5 Keller, TX > Doug K6JEY > > > > > ______________________________________________________________ > 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 bbaines at mac.com From n6kr at elecraft.com Sun Feb 21 23:02:48 2021 From: n6kr at elecraft.com (Wayne Burdick) Date: Sun, 21 Feb 2021 20:02:48 -0800 Subject: [Elecraft] K4 10MHz Reference level??

On the USB port the Right and Left audio stream are identical. (so both L and R is MAIN audio now) I did check on new firmware and I did an MCU LD with all the latest versions available. (which were already loaded anyway) The USB problem was still there. Once again an MCU LD. The audio via USB is still only MAIN (at both channels), no SUB audio. An EE INIT with some older configurations. This should not have any impact and it didn't; no change. CAT is working OK via USB. Different cables make no difference (as expected). Changing L-MIX-R to different settings makes no difference (as expected) Besides USB, power and antenna nothing else is connected to the K3s. After some K3s power cycles the reverse is now happening. USB audio is only SUB audio (both R and L channel) and no MAIN audio is present The rest of the audio outputs remains OK. I did check USB audio on 2 different PC's (both WIN10) with various audio programs which are using Right and/or Left channel audio input (WSJT-X, MSHV, Visual Analyser). All have the same issue. Windows 10 settings are OK, mic. input is set for 2 channels. There are no other programs running, requiring audio input. Visual examination of the KIO3B boards revealed nothing. Anyone with some bright ideas that could help me out? 73 Henk PA0C PS: I did sent a mail to Elecraft support, but hope to get some feedback from this group as well. -- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. https://www.avast.com/antivirus ______________________________________________________________ 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 jc_ki7y at q.com From maudeij at gmail.com Mon Feb 22 01:53:11 2021 From: maudeij at gmail.com (Ian Maude) Date: Sun, 21 Feb 2021 22:53:11 -0800 Subject: [Elecraft] K2 filter optimisation In-Reply-To: <78361f08-8022-950d-b5e0-80f351083460@cox.net> References: <78361f08-8022-950d-b5e0-80f351083460@cox.net> Message-ID: Thankyou to everyone for ideas.

I used to use a CM500 with excellent results, but when I got hearing aids I found that an "on the ear" style rather than an "over the ear style" was better for me. I found a $6 gaming headset that was great. However, I ran over the cord once too often with my chair and got an intermittent in the cord. Rather than try to fix it I decided to replace it and got an INSIGNIA gaming style headset from BEST BUY for about $24 as I recall. The EQ settings I used with the CM500 worked very well with the first cheap headset and I have not changed then for this one. Locals, who know me well enough say that I sound very natural with good clean audio. One person said that they thought I should crank up the gain and compression to assure pileup busting... but that was not a priority so I left it alone. I was VERY happy with the CM500 but am even happier with what I have now. There may be technical differences between an electret and a condenser but as a "mid dufus" I will yield to others in that regard. I think that "some" condenser mics may require higher bias than the K3 supplies, but again I must yield to others, who clearly know more about such matters than do I.

Before W6XU turned our contesting club onto the CM500, I was using one of my RE16s in the shack on an AKG boom stand. It was awkward, but great TX audio. A boom mic headset like the CM500 is far superior for operating. 73, Jim K9YC From n6kr at elecraft.com Mon Feb 22 16:14:30 2021 From: n6kr at elecraft.com (Wayne Burdick) Date: Mon, 22 Feb 2021 13:14:30 -0800 Subject: [Elecraft] Noise blanker and APF test recording Message-ID: <27489FC9-5C40-4E25-A2FE-7754D8D6DC32@elecraft.com> A brief K4 audio sample can be downloaded using the link at the end of this email. ?This recording hows how the new K4 noise blanker algorithm can reveal a signal buried under loud noise.

This was a radio designed to only send and receive on the 20M PSK subband (14.070-14.074). Coupled with a computer to run PSK software it made a very effective travel radio, and I made many QSOs with it. In the modern age, a KX2 is about the same size, but covers 80M-10M and is basically a HF HT. Many of the JS8Call people are using modern Raspberry Pis to run the software, and JS8Call uses the same encode/decode/modulation as FT8. (It allows rag chewing.) For myself, I could probably change the frequency on my PSK20 to work on the 20M FT8 band, but it's not a high personal priority. 73 Bill AE6JV On 2/22/21 at 10:36 PM, elecraft at mailman.qth.net (Doug Millar via Elecraft) wrote: >I have been wondering for some time- How will FT8 change ham >radio equipment??

The effectiveness of the K4 NB will be a major factor for me. FWIW, I have found the K3 NB to be vital in my locality and have depended on it a lot (for hundreds of CW QSOs in the recent SKCC event), its major fault being key "clicks" from adjacent CW signals leaking through when NB is engaged. I'm wondering how well the K4 handles nearby signals when the NB is on, compared to the K3. Also, I'm wondering how well the K4 NB might handle real key clicks produced by mis-adjusted transmitters, of which there seem to be many these days. 73, Drew AF2Z On 02/22/21 16:14, Wayne Burdick wrote: > A brief K4 audio sample can be downloaded using the link at the end of this email. > > ?This recording hows how the new K4 noise blanker algorithm can reveal a signal buried under loud noise.

It removes pulse noise that would otherwise cause the panadapter noise floor to rise, where it might obscure weak signals. The display NB can be turned on automatically at the same time that the receiver blanker is turned on (AUTO setting), or turned on/off manually. Either way, the level settings for the display and receiver blankers are independent and per-band. While recording the noise sample I just provided, I had the display NB on as well. It knocked the noise level on the panadapter down by about 20 dB. Weak signals could be clearly seen. 73, Wayne N6KR > > On Mon, Feb 22, 2021 at 2:15 PM Wayne Burdick wrote: > A brief K4 audio sample can be downloaded using the link at the end of this email. > > ?This recording hows how the new K4 noise blanker algorithm can reveal a signal buried under loud noise.

Hi Wayne, Have your beta testers (or other users accumulated any experience blanking with any of K1JT's modes? I've got a couple of solar farms as neighbors that make weak signal work tough on 6M during the day, and other sources in one of the homes that makes a mess during the evenings (I suspect something home entertainment related). It's especially problematic when trying to stretch meteor scatter to it's practical limit. 73, Jim K9YC From Mike.Carter at unh.edu Tue Feb 23 08:40:53 2021 From: Mike.Carter at unh.edu (Mike K8CN) Date: Tue, 23 Feb 2021 06:40:53 -0700 (MST) Subject: [Elecraft] Sudden loss of K3 RX sensitivity In-Reply-To: <2d5a5eed-0f60-c578-2e25-d0072b4ad2f1@comcast.net> References: <2d5a5eed-0f60-c578-2e25-d0072b4ad2f1@comcast.net> Message-ID: <1614087653869-0.post@n2.nabble.com> Pete, There was a similar report on the forum last year from Per-Tore, LA7NO.

Keith knowns more about the K3 than almost anyone. That 3db figure stands out for me, though. For a component failure or a misadjustment I would expect something else. This sounds more like the antenna is being split, going to another place along with the main RX input. Is it possible you are feeding the same antenna input to both main and sub RX? It will be interesting to see what you and Keith come up with. 73!

My laptop is currently connected to the USB port on the rig. According to the K3S manual, that should handle all the necessary communications between the laptop and the rig (I think). The N1MM documentation does not make reference to a USB connection, only to using a line out port from the rig to an audio input on the laptop, in my case that would be a combined microphone/headset jack. Between the three CW reader engine options discussed in the N1MM documentation, I think I would go with Fldigi. I would appreciate any ideas/tips/comments, especially from anyone who has specifically set up this Logger/rig combination.

For a long time, I never needed one. I really could use a switchable antenna option however.? I saw a comment on this reflector a few years ago, about a fellow who made up a replacement board to provide that function. He offered the empty boards along with a parts list. I bought one and then promptly forgot about it. The board is dated 2016.? Mine is labeled "Copyright Arcom 2016 KANT3 REV 1.0."? When I found it in my junk pile, I had no idea what it was! A few folks on this reflector clued me in and I decided to try to build it up. The construction is quite simple with the exception of three teeny weeny surface mount shift registers: TPIC6C596PW in the SO16 size. I am 76 years old and started to have hand tremors about 15 or 20 years ago. It has progressively gotten worse to the point where I was a bit worried that I would botch the solder job with these small parts. I can still solder hand wired and leaded components, but chip caps and FETs in small sizes can be impossible. My 432 MHz preamp has a HEMT that looks like a grain of sand. When it gave up the ghost, I had to farm that job out!? Well I decided to try and slide the KANT3? IC parts into position. Then I perched a small 1/4" socket on top to hold it down. I figured if I could solder one lead down I might be in good shape. Well it worked. I managed to solder all three shift registers to the board. I installed the new board in one of my K3s and set it up as a KAT3. It now will switch between Antenna1 and Antenna2 just fine. I did not read the instructions carefully. I should have!? The 12 volt Omron relays do not go on the board with the groundplane (and where they are silk screened!)? You must put them on the backside of the board. There was also a comment about shorting out pins 13 & 14 of one of the shift registers. Looking at the schematic, I think this is to give added current capability for driving the two relay coils.? I also found an unlisted part, C-14, a 0.01 capacitor that goes across one of the relay coils. Make a note of that if you are ordering parts.??? Also be aware that the shift register is available in various package sizes. Be sure you get the correct one. I had to re order mine! I know a few folks had ordered the PC boards, and at least one made the same mistake with the shift register package that I did. So it all works just fine, and is a great addition for my K3. I can now easily switch between my 160 meter vertical and my outboard antenna tuner and doublet for 80M and above. 73 Dave K1WHS From robertkhand at hotmail.com Wed Feb 24 16:12:22 2021 From: robertkhand at hotmail.com (Robert Hand) Date: Wed, 24 Feb 2021 21:12:22 +0000 Subject: [Elecraft] Secret K4 thread?

Normally no trouble, as I just use my trusty RIT control to move up and copy him, so I can keep my TX on the original frequency.

If you're running N1MM+ Logger the solution to this dilemma is to equalize the A and B VFOs at the beginning of the run and then turn on Split mode. Then your transmitter will be locked to the VFO B frequency and the receiver can be tuned with the big knob rather than the little RIT knob. This works fine in Diversity mode and I use it all the time for running. N1MM also has a nice configuration feature that will automatically retune the receiver to the TX frequency every time you log a station (at least if you're using ESM). 73...

I'm a die-hard contester and have the tendency to view things through that filter. It's easy enough to simply re-tune the receiver when necessary to return to your transmit frequency, pretty much exactly like you'd have to do with the RIT knob. You can also do it without a manual re-tune. If you're running split and tune the receiver? (VFO A) slightly off your transmit frequency you can easily return the receiver to the transmit frequency by executing two front panel key presses: A/B followed by A>B. This first puts VFO A on your transmit frequency and the second equalizes the transmit and receive frequencies. You can easily assign the pair of keystrokes to a single macro and store it in one of the PF presets. That's what I do with my setup -- I then actuate the macros using the programmable buttons on my K-Pod. Once you get used to using the main tuning knob instead of the RIT knob you'll never want to go back. 73... Randy, W8FN On 2/25/2021 9:20 PM, Tom Doligalski wrote: > Thanks for the input.

The radar signals presented as an undulating "dragon" on the panadapter, blanketing about the lower 20 kHz of 40 meters.

It has been updated regularly with most options and could be considered ?almost K3S?. It has been back to the mothership once about 10 years ago for a quick fix due to lightning ESD. Recently though when changing modes from CW to USB/LSB or from DATA to AM it hangs in transmit. A quick press of the ?XMIT? button clears the problem and it operates normally after. It doesn?t hang on any other mode switches but if I change bands from a band on CW to a band on USB/LSB it will hang. On two occasions going from DATA to AM it froze completely and wouldn?t respond to any button and had to be powered off at the power supply. Here?s what I have tried so far: 1. Since the ?gold pin? mod hasn?t been done, I pulled the front panel, cleaned all the pins and replaced it. No change. 2. After it froze completely the second time, I forced an EEINIT, reloaded a good configuration. No change. So it appears to be a hardware problem. I haven?t contacted Elecraft yet because they seem to be in flux right now due to COVID and the push to get the K4 out the door. Plus, I do have a quick work-around as long as I avoid the total freeze. So if anyone has had a similar problem and solution or could tell me where to look I would appreciate it.

The radar signals presented as an undulating "dragon" on the panadapter, blanketing about the lower 20 kHz of 40 meters. The panadapter's own noise blanker slayed it, though, knocking it into the atmospheric noise. Next time this pops up I'll do a video. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to louandzip at yahoo.com From ghyoungman at gmail.com Sat Feb 27 13:38:31 2021 From: ghyoungman at gmail.com (Grant Youngman) Date: Sat, 27 Feb 2021 13:38:31 -0500 Subject: [Elecraft] Buyer Beware!

You're pointing fingers in the wrong place. As is typical with this scam (which has been ongoing for years now), the listed seller?s account has been hacked by a malevolent third party. You can pretty well guarantee that the listing is fraudulent, and has not been posted by the seller shown with the ad. Odds are he doesn?t even know it?s out there. It may be that seller?s account, but it isn?t that guy.

Please read the KIO2 documentation: any serial device may only be connected *if only pin 2, 3, 5* are connected. If you connect a serial device with the other pins connected, which the KUSB as well as most other devices have, *you can cause serious damage to your K2*. It is essential that the other pins are left unconnected, they are used for other signals and the RS232 signals give voltages that cause damage. So, if you use the KUSB, make sure to insert a short cable that ONLY connects these 3 wires, NOTHING ELSE. How much damage is done partially depends on the hardware mod version of your K2. The "B" mods includes some modifications that should limit some of the most serious damage, like blowing up the main processor of your K2. There is a document somewhere that describes what damage a K2 suffers because of this; it's a long list Despite the fact that the KIO2 sports a DE9 connector, it really isn't a standard serial port. In hindsight, Elecraft should have chosen a DE15 connector instead (making sure that a "VGA cable" would not cause damage.

There is a document somewhere that describes what damage a K2 > suffers because of this; it's a long list Apologies for replying to my own post - didn't want Dave to sustain any more damage! - but for those who have done the unthinkable and connected a regular RS232 device to KIO2, https://folk.universitetetioslo.no/sverre/LA3ZA/blog/K2/N0SS/k2_wrong_ser_cbl_damage.pdf should be helpful information. Step 10 of the K2 "Upgrading the elecraft K2 to revision B" document on the Elecraft website has a valuable step that I missed when I did other upgrades. BTW, if your K2 is the 10W version, you don't use the RS232 port and you don't have the "K2 amplifier keying circuit" that can be found on the Elecraft website, it is possible to put that circuit inside a DE9 connector hood: have a DE9-M connector that plugs in the KIO2, and a cable to key your amplifier. I added another transistor to switch a small LED so that the connector now lights up when the K2 is transmitting. I use this to key a chain of transverters for the QO100 satellite. And it avoids drilling a hole for the PTT key plug. 73, Geert Jan From k4to.dave at gmail.com Sat Feb 27 17:31:06 2021 From: k4to.dave at gmail.com (Dave Sublette) Date: Sat, 27 Feb 2021 17:31:06 -0500 Subject: [Elecraft] KIO2 and KUSB Message-ID: Problem is fixed.

I recently purchased a KX2 (#757) from a friendly member of this list. I have a local 10m meetup I attend frequently, and I noticed a strange behavior that I'm now able to replicate. When I first switch to 10m, I have extremely low output power (one bar on the RF meter), even when set to 10w. I have to keep transmitting for 30-60 seconds, and if I do, the output power starts to work its way up to the full 10w. As you talk, you'll see 2 bars, 3, then 5, etc eventually to the full 10w.

I isolated this problem this morning and can now replicate at will.

Of course set at different mic gain levels, always per the manual which as you said suggests 5 bars of ALC. I have tried lower and higher mic gain settings just for fun, with the same results. I don?t think this is an mic gain issue, as it does happen on any other band I?ve used (80, 40, 20) and only on 10m. I made a video showing the behavior here, let me know what you think: https://youtu.be/7wWd6vRYSxo I have had great QSOs on 40 and 20 so far, and feedback that my audio is extremely low on 10 until it ?warms up? and then reports there are excellent, also. I usually talk on 10m for 45-60 minutes every weekend morning and it performs well once it?s up to power.

It *sounds like* you are still in AFSK A and not DATA A. By default AFSK A has a narrow audio filter on the input of the modulator process (DSP) that restricts modulation to a very narrow range around the AFSK tones (e.g. 2050-2350 Hz for 2125/2295 tones). 73, ...

Did Elecraft say anything about doing a TX gain calibration? This can be done with the KX2 utility although I haven?t done it on mine, just on my K3. It sets the per-band gain coefficients Be sure to save the current CONFIG file so you can restore it if needed. You will need a good dummy load an a stable power source. The procedure is on p. 38 of the Rev A5 Manual.

The instructions for this version have a more limited history of changes. https://web.archive.org/web/20150905061319/http://www.elecraft.com/manual/K2_Rev_2_FW_Rev_J.pdf I hope this helps a bit more................
