Message-ID: <960148DE-9414-450F-894E-251A8B910314@me.com> I was out this morning trying some antenna configurations at the park, ten different setups, one one of them gave me a HI CUR error. It was on 20 meters with 10 watts and with the current limit set at 2.5 amps, left over from when I was working on the radio a few days ago. The SWR was 1.2 into a 49 foot wire using the KAT2 tuner. Am I correct in understanding that high current in the power amplifier is not bad in and of itself, as long as it stays below the point where it damages the transistors? In other words, if the power setting is high (here, 10 watts) then with a good antenna the PA will see high current just as part of normal operation? And that the goal is to set the limit high enough (3.5 A) so that the error doesn?t occur AND the transistors don?t burn out?

If you have questions about any part of it, please ask. A Hi Cur message does not mean that the PA transistors are in danger. All it means is that the current draw is greater than what is set in CAL CUR. Set CAL CUR to 3.5 for most operation, and all should be OK.? If you have 'special conditions', like when running on a battery, you might want to set CAL CUR to a lower value to indicate that the battery voltage is getting low. Check your power source voltage at the K2 end - ideally it should be 13.8 or even higher. What does the voltage have to do with the current draw, you may ask -- The K2 attempts to maintain the power output requested by the Power knob.? Do a little ohms law - if for a power of 10 watts, you need 13.8 volts and 2.5 amps, if your voltage during transmit drops to 12.7 volts, the current MUST go up to maintain that 10 watts output.? The K2 firmware does just that, and if the current increases above the CAL CUR setting, it will flash the HI CUR message and fold the power back.? That is how the K2 protects the PA transistors. When operating on batteries with CAL CUR set at 2.5, you can expect a HI CUR message at 10 watts. So check your power source voltage in transmit (use the K2 display to see the internal voltage) and if you have less than 12.7 volts, that is reason for the Hi CUR message. You can increase the CAL CUR setting to 3.5 with no harm - in fact, that is what the setting should be if the KPA100 is installed.? CAL CUR and HI CUR relate only to the base K2, and not to the KPA100 - that is an indication that a CAL CUR setting of 3.5 is not a problem.? When I was repairing K2s, I always set CAL CUR at 3.5 even if they were only a K2/10. 73, Don W3FPR On 9/2/2021 4:56 PM, Douglas Hagerman via Elecraft wrote: > I was out this morning trying some antenna configurations at the park, ten different setups, one one of them gave me a HI CUR error.

I too am a CW guy and my MH3 only hangs on a hook. The case "studs" appear to have cracked under the weight of the cord. I emailed Elecraft support and was told the Mic was no longer under warranty and I would need to buy a new mic. No one answered my follow up email asking if I could get a discount on a replacement mic. In any case I opted to just repair what I have. If you have not unscrewed the screws from the case and all three studs are broken, like mine was, the studs can easily be epoxied. I first removed ALL the working parts from the case. Keep an eye out for the button spring which is just a small flexible "rod". There was also a small piece of broken plastic which was used in the cable retainer. Once the case is emptied out the base where the studs broke can be accessed. I put a dap of epoxy on the studs and the base. I put a little inside the actual stud where it meets the base. Next I put the two shell pieces together and held it in place with a rubber band. After 24 hours I removed the screws and added more epoxy around the studs for additional strength. I also epoxied in the broken cable retainer. Just make sure you don't put epoxy where it might interfere with the electrical parts of the cord. After another 24 hours I reassembled the mic and everything functions as expected. It's a bummer that the plastic casting is inferior. But with the reinforcement it is now better than new. 73 Len -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ian Liston-Smith Sent: Friday, September 03, 2021 3:09 AM To: Elecraft List Subject: [Elecraft] MH3 mic case Does anyone know if Elecraft sell replacement cases for this expensive microphone?

My strategy was rather to embed the post into a good amount of epoxy. There is really no force on the mounts other than the pull of the screws. I suspect that the plastic "studs" were a bit short and then pulling on them with the screws started a fracture. Once the stress of that is done they should not stress much once epoxied into place. Since there is no lateral force I doubt adding fiber is going to make much difference. len -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bill Frantz Sent: Friday, September 03, 2021 11:21 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] MH3 mic case I like to mix in some short lengths of fiberglass with the epoxy.

If the machines are not adjusted properly -- temperature, pressure, dwell, cooling, etc., it's possible to make parts that are extremely brittle. Sometimes the stress of assembly and shrinkage over time causes them to break spontaneously. I remember an incident in which an engineer demonstrated a prototype to an important overseas client -- and it broke in his hands.

My theory is that the large lump of steel plate (27g) in these mics could contribute as it means the mic has more kinetic energy when dropped. Three of the mics I repaired were damaged in shipment from USA to New Zealand. When I repair them, I replace the steel plate with an identically shaped piece of Customwood (MDF). This supports the microphone element, does not detract noticeably from the speech quality and reduces the weight by about 20g (happy SOTA ops :-) Good luck, Geoff ZL3GA On Sat, 4 Sept 2021 at 09:38, Don Wilhelm wrote: > Ian, > > Elecraft has had a 'rash' of those incidents, but I thought they > addressed that with the mic vendor (yes, Elecraft does not stock parts > for the mic, they buy them whole from the vendor). > > There was some speculation a few months ago about the cause -- and I > don't know the answer.

I use a medium bandwidth (1 kHz) to allow for signals a bit off-frequency. For those who didn't know: this is the most common QRP CW watering hole. Even if the rest of the band seems dead, you'll still hear weak-to-moderate signals pop up near this frequency throughout the day. They'll often be calling CQ SOTA or CQ POTA (Summits and Parks on-the-air). If you hear these stations, please give them a call.

Maybe they're all on summer leave? Making forms for plastic moulding is extremely expensive and Elecraft did not make one specially for the MH3. Looking on ebay, https://www.ebay.com/itm/281509579500 finds a microphone that uses the same case. The electronics inside is different (and, frankly, the MH3's innards are a lot nicer than these ebay microphones) but the casing is the same. It has a different brand name on the case but that is only a sticker. You can make these ebay microphones work by changing the wiring a bit, especially for the down/up buttonw. The radios these are sold for use resistors on the PTT line to signal up and down, on Elecraft they are direct connections. And PTT and audio are on other pins so you need to change that too. When I have the microphone plug open, I always add a 5K6 resistor between the 5V and the mic output in the plug. This power the electret microphone irrespective of "mic bias" settings in the menu. And it makes the same microphone also usable on the K2 (where the up and down buttons don't work, alas). In defense of Elecraft, yes, their microphones are probably "also made in the east" but there is a difference in quality which will be quite visible when you compare them. Having said that, an electret microphone is an electret microphone and the reports on the air are not different. And, if the round plug is change for, for instance th Neutrik NTP3RC (see https://www.neutrik.com/en/product/ntp3rc) then the same microphone will also work on the KX3. You will need to change the wiring to make the buttons work but that is not hard.

Sometimes it don't pay to get up in the morning. First, I was having a CW QSO on 40M with a station in the East Coast... My K2/10 was driving the Tiny Linear - we were seeing 150W on the meter. Suddenly, the screen of the linear flashed bright white, and the RF went away, leaving me with the barefoot K2. Seems that 150W was Just Too Much for the little fan-driven heat sink, and the PA transistor shorted out. My fault, of course. I have a few more of those transistors, but I'll have to hold the power down, instrument the heat sink temperature, and put in some sort of protection. In the meantime... I installed the recently acquired KPA100 in my K2. Actually, that KPA100 came from ANOTHER K2, acquired on Ebay. I swapped it into my first K2, because that one has the V2 mods, including the upgraded crystals. So here I am, ready to continue hamming. My K2 ( now /100 ) is doing strange rf-in-the-shack'y things. If I send a bit of CW, my sent CW starts breaking up, and strange pops and clicks (like relays ) come out of the radio. Then when I stop sending, the radio is completely silent - no audio. I can see band noise and signals on the S-meter(bargraph) but no audio WHATSOEVER. Hitting a band button or the display button fixes it, and audio is back. Sometimes OTOH, when I stop transmitting, the audio comes back much LOUDER than it was before I transmitted. This all happens at any power level where the final is engaged. If I turn the power down to 8W or so, all is good. If otoh, I turn the power knob anywhere past that *click* where the PA comes on line, the bad things happen. Even at, say, 12W. I made up a short length of RG8/U with 4 Palomar 31-mix giant ferrite beads - a common mode choke. No difference. With a dummy load, all is good. No fuss no muss, it just transmits nice. The antenna is very low SWR. It is a 6BTV vertical about 100 feet up the hill from the house. There is an MFJ998RT remote autotuner up at the base of the antenna. It is grounded with an Ufer ground - 80 feet of #6 copper wire buried in the concrete pad, which is 70 feet long by 10 feet wide. If I turn the PA off, the K2 behaves well, even at the full 15W. Tune mode shows SWR 1.2 to 1. My K2 btw has the KDSP2 audio filter. - Jerry KF6VB From jim at audiosystemsgroup.com Sat Sep 4 17:31:01 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 4 Sep 2021 14:31:01 -0700 Subject: [Elecraft] Bad Ham Radio Day In-Reply-To: <3892f63216249d1451ef25ca1d584244@tr2.com> References: <5BB1AF1D-707B-4781-8278-8E3C52B19249@elecraft.com> <5b0511a2-f94f-ea23-bc00-af4d88d980e0@nk7z.net> <67b28685-b2e0-894f-2c91-7bae5d5cafdd@foothill.net> <3892f63216249d1451ef25ca1d584244@tr2.com> Message-ID: On 9/4/2021 2:03 PM, jerry wrote: > I made up a short length of RG8/U with 4 Palomar 31-mix giant ferrite > beads Palomar SELLS these cores, at high prices.

Fair-Rite MAKES them. 31-mix is supposed to be the hot ticket for HF common mode chokes. One turn through one core is supposed to be 98 ohms at 5MHz. So four cores should give me about 400 ohms, which should give a worthwhile attenuation in a 50 ohm system. Thanks for the references. It's interesting that I am not having any such problems with any other equipment. My TS590S works fine. So did the K2/10 with my tiny linear. And a QRP-labs transceiver. And a uBITX transceiver.

Hence why K9YC says multiple turns through a core is needed. Sometimes multiple cores in series. But as I read you email, I think I?d focus on what?s different or amiss with the K2 since the other rigs aren?t exhibiting the problem. I?m sure someone who knows the K2 will chime in? 73, David - N5DCH > On Sep 4, 2021, at 3:48 PM, jerry wrote: > > On 2021-09-04 14:31, Jim Brown wrote: >> On 9/4/2021 2:03 PM, jerry wrote: >>> I made up a short length of RG8/U with 4 Palomar 31-mix giant ferrite beads >> Palomar SELLS these cores, at high prices.

Is your KPA100 upgraded with the latest updates, AND the new shield? For the latest update, peek between the shield and the board - If you see blue toroid cores at RFC1 and L16, then it is up to date - OTOH, if you see red core toroids at L15 and L16, install KPA100UPKT. On the shield, it should have spring clips to ground it to the sides of the base K2 - make certain that the area where the spring clips contact the sides of the base K2 has been cleared of all paint - sandpaper works. Also check the width of the slot in the shield next to the SO239 ANT jack - it should be only a bit wider than 1/8 inch.? If it is the older wide slot, replace the shield with KPA100SHLDKT. Also, there should be 2 bent-over solder lugs that connect the top of the shield to the SO239 jack.? Make sure they are soldered together.? If missing, they are supplied as part of KPA100SHLDKT. 73, Don W3FPR On 9/4/2021 5:03 PM, jerry wrote: > Hi Elecraft list & Bob, > > Sigh.?

The MH4 is usable with the K2 and K3, the MH3 is usable with the KX2 and KX3. The plastic case for both microphones is the same. 73, Don W3FPR On 9/4/2021 6:26 AM, Geert Jan de Groot wrote: > >> Does anyone know if Elecraft sell replacement cases for this >> expensive microphone?

Thanks for the references. I'm the guy that did the original work on this, beginning in 2003, when #31 was a brand new mix. I got five of the first #31 toroids from the pre-production run, a few months after I suggested that they would be quite useful. My first publication was a paper to a 2005 international meeting of the Audio Engineering Society, of which I'm a Fellow. First publication to the ham world was RFI-Ham.pdf in 2007. And you are mistaken about the value of four cores at HF. Study that paper. It's a tutorial on how RFI happens and how chokes work. 73, Jim K9YC From kevinr at coho.net Sat Sep 4 22:45:12 2021 From: kevinr at coho.net (kevin) Date: Sat, 4 Sep 2021 19:45:12 -0700 Subject: [Elecraft] Elecraft CW Net Announcement Message-ID: Good Evening, ??

Some various 43 material examples, which demonstrate CMR is a function of device inductance. https://www.kn5l.net/Balun-CM/Balun-43material/ FT140-43 7T CMR measured using four different methods to ensure correlation and correct CMR measurement process.

So when I obtained a new Meanwell RSP-3000-48 switching supply to replace the HP, I used a similar method using two ferrite torroids sized for RG-8x with two clamp-on beads for good measure.? On the 48v output I used two torroids sized for RG8 in series with an extra loop thru them both: http://www.kl7uw.com/6M-EME-CONTROL.jpg I see no switching noise on my K3 that is only two foot from the PS.? The coax beads are probably mix-31 as they are sold for the general HF ham market as common mode RF filters on coax lines. The original tip for filtering the HP PS came from Lance-W7GJ who did many of the first conversions of the Harris ch.2 TV linears to 6m ham use. I am building a 1200w MRF1K50H HF/6m (W6PQL) linear to replace my Harris to use with my K3/10 driving with 3w to the new amp.? So I will be running QRO on HF in a couple months. 73, Ed - KL7UW From k6dgw at foothill.net Sun Sep 5 12:55:08 2021 From: k6dgw at foothill.net (Fred Jensen) Date: Sun, 5 Sep 2021 09:55:08 -0700 Subject: [Elecraft] Bad Ham Radio Day In-Reply-To: <079f98a25f2b150d804704073d31492a@tr2.com> References: <5BB1AF1D-707B-4781-8278-8E3C52B19249@elecraft.com> <5b0511a2-f94f-ea23-bc00-af4d88d980e0@nk7z.net> <67b28685-b2e0-894f-2c91-7bae5d5cafdd@foothill.net> <3892f63216249d1451ef25ca1d584244@tr2.com> <1a6c2af7da7ff46816fa222e61a634aa@tr2.com> <079f98a25f2b150d804704073d31492a@tr2.com> Message-ID: <1335354c-fcba-a63f-d153-870a366da1a5@foothill.net> Glad you got it working.?

If so, check the dash spacing on your paddles (increase the spacing) and clean the paddle contacts. Also increase the spring tension on the dash side. It sounds to me that somehow the contacts of the paddles may be 'getting stuck'.? I cannot think of any this could be a problem inside the K2 - unless RF Board R1 and R2 are something other than 220 ohms and/or not well soldered.? You can remove the left side panel to check R1 and R2. 73, Don W3FPR On 9/7/2021 12:16 PM, wks9478 at charter.net wrote: > I am using a K2 pre-3000 SN model with all the upgrades to the new PWB > configuration installed.

Here is an observation with the noice reduction NR. The bands are quite noisy here. So I use NR ADJUST set to 4 or 5. - When I last used the 40m band, mode was LSB, ? bandwidth was 2.8 kHz, and NR was ON. - Switch from some other band back to 40m. - Disable NR and immediatly re-enable it again. - For me it seems that the noise levels (the audio) ? before disabling NR and after re-enabling it are ? (quite a bit) different. But they shouldn't. The test with the 40m band is just an example. I (think I) observe this on other bands as well. Am I crazy or is this real?

You must connect with a cable matching the special pinout first. If you try a straight connection it will fail. Try the K2 and its cable into an interface unit such as the Modular Technology interfaker (like https://www.ebay.co.uk/itm/224519972647 ) or something smaller such as https://cpc.farnell.com/pro-signal/t-mb460p/rs232-check-tester/dp/CS11237?ost=pro+signal+t-mb460 Check you have enabled the necessary handshake pins, and are receiving the same from the USB interface.

If that signalling is destroyed, the set won't be able to do anything useful, so won't be able to operate the serial port. In fact there seem to be two pins that are used for signals that cannot tolerate RS232 voltages. This is only a may, because it depends on which wires in the cable are actually connected at the other end. The special cable basically leaves some pins unconnected. -- David Woolley Owner K2 06123 On 10/09/2021 13:12, Andy McMullin wrote: > You are using the special RS232 cable aren?t you?

I've heard the service dept turnaround in CA is very long so I might not see it the rest of the year if I sent it in and wanted to avoid that if possible. I've followed advice suggested here with no lasting success. Especially on 6M the power sometimes takes a long time deciding to reach the setpoint. Sometimes it will be OK, but a few hours later after just sitting there, it again won't, and drops to a low output level. I've run the transmitter gain calibration routine again and again and it fails. Sometimes I get an ERRTXG on 160, 80, 40M. Sometimes the 5W calibration shows errtxg as it runs but the utility says the calibration had succeeded. I've checked that the bandpass filters are OK by using an antenna analyzer with an attenuator to check receiver sensitivity- all bands seem pretty close. I've rechecked if the LPA FET's are ok (I changed two last year), and set their bias current levels again and all seems well with them. I've upped the supply voltage- that seems to work for a day or two but then same old problems come back I've replaced the fwd and rev power meter Schottky diodes, no fix. Sometimes when the transmitter fails to reach the set power level, I can tweak the pwr knob and it will reach the changed level, but sometimes not and it falls back to a lower value. On 6M, while in "tune" if the power does not reach the setpoint (e.g. 30W) and I turn the pwr knob down below 12 where the 100w amp is bypassed and then turn it back up to reengage the 100w amp, the power will sometimes reach and stay at the setpoint (30W). But that condition does not stay Ok too long. The transverter output also exhibits similar power problems I've reloaded the firmware. The utility initially reported "checksum reconciliation value" and I have no idea what that means. And finally, this weekend, when I set the receive mode to data-a, the audio output had shifted to a higher freq spectrum width (e.g. 500-3300) on the WSJT spectrum display with clearly more hiss in the speaker. Cycling the xtal filters, normalling the shifts and widths had no effect. Changed the mode to USB and the audio spectrum was normal, change back to data-a and it was shifted. So I operated WSJT-X in USB. Hours later, data-a was back to normal. First time I've observed that. Today it is AOK. GOK what happened Saturday.

Thanks for any ideas. > Generally, when miscellaneous weird stuff happens to a piece of complex equipment - stuff that seems to have no relationship the one to the other- my first instinct is to check the power supplies. Not just the main 13.8V power, but also any lower ( or higher! ) transformed voltages. Here's an example - I have a Fluke 3000 signal generator that mostly works....except when it doesn't. It has a pair of 18V power supplies - plus & minus. The RF guts are in a multitude of little shield cans. In each can - well, in most of them - are a couple of 10uF tantalum caps, one on the positive leg, one on the negative leg. Once in a while, one of them will short out, disabling that particular power supply. When one of those 18V supplies goes out, pretty much everything dies. Power supplies are like octopi - with tentacles going into every part of the radio. No guarantees of course - but when seemingly unrelated stuff starts failing, that's where I look first. - Jerry KF6VB From jim at audiosystemsgroup.com Mon Sep 13 17:30:02 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 13 Sep 2021 14:30:02 -0700 Subject: [Elecraft] Unique QSO In-Reply-To: References: Message-ID: On 9/13/2021 11:18 AM, Wayne Burdick wrote: > Bill, W6H (AKA W8TE) I suspect it was K8TE.

My operations are largely SSB, with the occasional JT mode digital on 160 m and 6 m. I have not found the KPA1500 power output stability to be an issue, despite the fact that the efficiency is degraded. The heatsink temperatures are certainly no worse than at higher power operation and the only real penalty is a small hip-pocket one when the power bill arrives. On the IMD front my own quick measurements show that the overall picture is also no worse than at high power but it's not much better either, although the higher order products are a bit lower. The KPA1500 manual is a poor effort for a premium product and, in areas like IMD specifications and any associated discussion, it's almost an exercise in studied disingenuity. An abiding irritation is the lack of a decent block diagram showing e.g. the connection points for signal and control lines. In the end, the amplifier is a good one although given our antipodean locations, it'd pay to review the SPE and other offerings both in technical and support terms. Personally, I like the Elecraft form factor and the relatively large amount of air in the two-box implementation. My relatively early serial number RF deck has been back to the US once for service and upgrade and, while I was particularly grateful to a few Elecraft people for help at an obviously difficult time (CV19), the overall experience was very average. 73, Peter (VK6HP). -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Barry Simpson Sent: Wednesday, 15 September 2021 6:15 AM To: Elecraft Mailing List Subject: [Elecraft] KPA1500 Power Level I have had a quick look through the KPA1500 manual and could not find any reference to running the amplifier at a lower power level than the rated 1,500w.

In my limited contact with SPE amps, I'd say the Elecraft amps are substantially cleaner. One of our neighbors was getting reports of a dirty signal on 6M, so one of the guys went to his QTH to help him diagnose and clean it up, while I watched on a P3/SVGA. Part of the problem was that he was running at low voltage; sidebands dropped by about 6 dB when he switched to high power (he was only running 400-500W), but sidebands were still very nasty, looked like noise rather than the small but pronounced peaks spaced in 300 Hz increments from N5KO's FT8 signal. I had one for a few weeks, but dumped it because it wasn't very clean. 73, Jim K9YC From K8UT at charter.net Wed Sep 15 07:04:34 2021 From: K8UT at charter.net (Larry (K8UT)) Date: Wed, 15 Sep 2021 11:04:34 +0000 Subject: [Elecraft] KPA1500 Power Level In-Reply-To: <002301d7a9d1$ef8aa9a0$ce9ffce0$@com> References: <002301d7a9d1$ef8aa9a0$ce9ffce0$@com> Message-ID: Barry, If you've connected your KPA1500 to ethernet/WiFI, you can display the amplifier's input watts, outputs watts, and efficiency in real time as you vary power levels.

NOTE; After a successful Gain-Cal, then never, ever, TX at exactly 5 or 50watts (or 1.0MW) as that can cause an inadvertent TX gain cal and mess it up. To me, it would appear the LPA is weak. Check your Watt-Meter Cal, or make sure your WM LP is around 65-100 and WM HP is 25-55 typically. Then if you can get the gain cals to run, send me the numbers, IE click Display TX Gain Summary and cut and paste. *However, I just noticed you mentioned the MW gain cal has issues, so it could be before the LPA/KPA and would be the Band Pass Filter adjustable caps. Also from my notes; Slow ramp up of power, mainly on the upper bands,? can be D1 E560040 burnt (or bad solder joint) and/or bad Q6 E580026 on LPA. (power ramps up starting very low). If Q6 shorts, it can take out Q3 E580030. **REPLACE D1 *and* Q6 if the solder joint is bad!!! Fix; Replace ALL THREE at same time! Q3, Q6 & D1 on LPA. Note; This can also just be normal operation of Firm Ware overshoot protection. (power goes quickly to near (~80%) desired power, then ramps up the final percentage in seconds. This happens if you; 1. Change desired power, 2. Change bands, 3. Power cycle radio. So, set desired power, then long press XMIT to do a TUNE (with TUN PWR at nor), or Key up on FM (if you have a FM filter). The go back to your desired mode and it should reach good power quickly.

The K2 "A to B mod" has some modifications that at least seem to reduce some of the damage. I don't remember it being announced as such, but reviewing the mod status of my K2 after some time found some snippets I had not seen before. Things still would not work and I am not sure the K2 is fully protected but some protection is added and the damage should be less.

You will need a straight-through cable. BUT, you also need some pins removed. The power pin of the K3 is not compatible with the power pin of the KPA500 or KPA1500, and will result in the problems you have seen. The cable is described in the KPA500 manual, rev E1 on page 45.

You cannot use a VGA cable with the Y-BOX or any Elecraft radio because they almost always short too many pins to ground.or to each other. A straight 15 pin M/F (non-VGA) extension would have worked OK to extend the Elecraft ACC cable. I supply these with the Y-BOX. I can also obtain longer lengths. The Y-BOX transforms standard 15-pin straight cables (not VGA) to KPAK3AUX equivalent, plus some extras like powering on the amp. from a K3 or K4 macro, or optionally opening the keying line so that an external device like a SteppIR controller can protect itself from high power while it is moving. The "Key Line Interrupt" gender changer supplied with the KPAK3AUX cables is not needed with the Y-BOX since that's built into the Y-BOX as a jumper option. 73, Bob, N6TV https://bit.ly/Y-BOX On Sun, Sep 19, 2021 at 5:46 AM Eric Norris wrote: > I must point out that N6TV's Serial and Y boxes can be configured to use > VGA cable between K2/K3/K4 and Elecraft amps.

References: <004801d7ad79$eb2d46a0$c187d3e0$.ref@snet.net> Message-ID: <004801d7ad79$eb2d46a0$c187d3e0$@snet.net> Thank you all for the suggestions and encouragement. I am optimistic that it is now fixed. I believe it was one of the TMP coax plugs that had a faulty connection. But by shot gunning fixes I cannot pinpoint that specifically. Below is the long story: Earlier I had replaced the wattmeter diodes, and it was suggested I do the wattmeter calibration. I had not been aware there was a WM calib, but it made sense since I had changed the diodes. So I did it. The LP calib was producing 4W on my wattmeter and I adjusted that parameter from 102 down to 070 to get 5W. HP was close to 50W but I tweaked it from 050 to 039 anyway. This made no difference in my transmit power problem. Tx gain calib passed at 5W but failed the 50W step with the power ?not settling? ?or converging to a consistent value and stopped at the 5.336 Mhz step. (Not a big surprise because I had noticed that when doing the wattmeter calibration, the power shown on my analog meter would slowly fluctuate, and later when trying a TUNE to 60W the K3 display would fluctuate erratically between 60 and 65. Didn?t think it should be doing that.)The 1 mW test had the same error wording. Learning about the wattmeter test showed there was a SYN calibration too, so I did it. This ran OK but made no change to the problem. Time to bite the bullet and start taking apart the radio to check connections, look for bad solder joints, burned parts, etc. Having no SMT rework tools, and imperfect eyesight, I would not attempt a fix but would cross that bridge later. So, on went the ESD strap, and the first step was to take off the top cover and remove the subreceiver, since it blocks the view and access of everything on top. It was easy to remove the sub-receiver, but I forgot how hard it is to install it- more on that later. In the process of removing the sub, many of the little coax cables get loosened, rotated, etc. The sub really crams these into tight spaces making it difficult to fiddle with them. Once the sub was out, I did remove, spray, wipe, and reinsert them solidly; plus I loosened the mounting screw of many of the PCBs and wiggled them about in their pin sockets. Wondering if perhaps the subreceiver was a contributor to the problem either with an internal fault or by inadvertently shorting something to its case, I powered up the radio, and to my delight, it now worked!!! Tune power would quickly reach the setpoint and stayed steady on all the band I tried. I ran the TX gain calibration routine, and it passed all!!! Next, I decided to do a better job with the PCB connectors by taking them completely off, checking them visually, spraying the pins and reinstalling them. That turned out to be an adventure with the boards that screw onto the metal front. Fat fingers make it hard to hold the tiny screws with a lock washer on the head and a split washer on the back, insert the board into the bottom connector, and not drop off the split washers. After many failed attempts, my solution was to put a tiny dab of dielectric grease on the screw threads sticking out the backside so that the split ring washer would not easily slide off. (On static contacts the actual contact areas are little high points that flatten a bit based on their hardness and the pressure on the contact surfaces. The actual contact area is a small fraction of the physical contact surface. Any grease is punched through and squeezed out from under them so is not a problem.) I also removed and replaced the front panel in a similar manner. It is easy to take off and put back on. I then decided to wait a few days before going further. Throughout the day I would do a TUNE and found the output power quickly reached the setpoint and was stable. With my dummy load, the K3 SWR readings came out to be 1.0 on all bands except 40M where it was 1.3. I took off the bottom plate and reflowed a few of the thru holes and then wiggled 3 of the trimmer caps in the 40M section. I could not locate the 4th trimmer. This made no change to the 1.3 on 40M, and that remains a mystery. Eventually it was time to put back in the subreceiver and finish buttoning her up. It is not easy to put in the sub. I rerouted some of the little coaxes to minimize them pulling on each other or getting caught between other parts. With the subrx chassis in place there is scant room to ensure the TMPs are all in snug. This does suggest maybe the original problem had to do with a TMP connector strained, or partly pulled out from the original sub installation. It took a few hours until I could satisfactorily get it done. Before putting on the chassis stiffener and top cover, I again tested the radio. All was fine. The last thing I did was to return the power supply voltage down to 14.0 volts. I felt having it up at 14.6 from a previous attempt to solve the problem was too high to leave it. Again, all was fine and it breezed through another TX gain calib run. My sincere thanks to all those offering suggestions and relating their experiences. 73, Chet, N8RA From 99sunset at gmail.com Sun Sep 19 21:41:23 2021 From: 99sunset at gmail.com (Steve Hall) Date: Sun, 19 Sep 2021 21:41:23 -0400 Subject: [Elecraft] 40 meter net 7.280, 9-19-2021, 1900Z Message-ID: Thanks to stations assisting with relays.

NOTE; After a successful Gain-Cal, then never, ever, TX at exactly 5 or 50watts (or 1.0MW) as that can cause an inadvertent TX gain cal and mess it up. To me, it would appear the LPA is weak. Check your Watt-Meter Cal, or make sure your WM LP is around 65-100 and WM HP is 25-55 typically. Then if you can get the gain cals to run, send me the numbers, IE click Display TX Gain Summary and cut and paste. *However, I just noticed you mentioned the MW gain cal has issues, so it could be before the LPA/KPA and would be the Band Pass Filter adjustable caps. Also from my notes; Slow ramp up of power, mainly on the upper bands,? can be D1 E560040 burnt (or bad solder joint) and/or bad Q6 E580026 on LPA. (power ramps up starting very low). If Q6 shorts, it can take out Q3 E580030. **REPLACE D1*and* Q6 if the solder joint is bad!!! Fix; Replace ALL THREE at same time! Q3, Q6 & D1 on LPA. Note; This can also just be normal operation of Firm Ware overshoot protection. (power goes quickly to near (~80%) desired power, then ramps up the final percentage in seconds. This happens if you; 1. Change desired power, 2. Change bands, 3. Power cycle radio. So, set desired power, then long press XMIT to do a TUNE (with TUN PWR at nor), or Key up on FM (if you have a FM filter). The go back to your desired mode and it should reach good power quickly.

It's working fine with my K3, but after it warms up - 40 degrees C or so - I start to hear a faint clicking noise. It is coming from the vicinity of the fan and heat sinks. There is a click every 10 seconds or so, I think whether I am transmitting or not. Fan control is working fine, and I bumped up the lowest speed to help keep the amp cooler. Let me know if anyone has seen this before. Meanwhile, I will keep using it and see how it goes.

It's working fine with my K3, but after it warms up - 40 degrees C or so - I start to hear a faint clicking noise. It is coming from the vicinity of the fan and heat sinks. There is a click every 10 seconds or so, I think whether I am transmitting or not. Fan control is working fine, and I bumped up the lowest speed to help keep the amp cooler.

Kenwood fixed all these issues with firmware updates, in one case issuing an update within a couple of weeks of receiving the first report. I wrote my first KAT500 defect report July 2018. There is still no released firmware update to correct this problem or any of the others I have reported since then. I understand that Elecraft is a small company with limited resources. I also appreciate the personal interaction I have had with the KAT500 and KPA500 firmware developers. That sort of interaction simply is not possible with Kenwood. However, the bottom line is that Kenwood fixed the reported problems and Elecraft hasn't yet.

One exception, to which I'm aware, is the Johnson Thunderbolt which uses a variable L along with variable C for the input components to the Pi L network. Otherwise, the Pi network input circuit is using a fixed value of L and a variable C for the frequency. Thus it is designed to match the output device Z only at rated power. I've performed power measurements on my KPA500 on all bands at 100 watts, 200, watts, 300 watts, 400 watts, and 500 watts output.

If you receive this data set be sure you understand that dissipation, heating, and efficiency will be strongly dependent on the complex impedance of the load. I have previously shared test data for my KPA500 but I made no attempt to record drive level and have no data for gain. My measurements were made to explore the influence of output power and loading on PA dissipation. Once you have this data you'll stop believing those who say there is no reason to match to better than 1.5:1. 73, Andy, k3wyc From FlatHat at comcast.net Wed Sep 22 20:24:33 2021 From: FlatHat at comcast.net (Richard) Date: Wed, 22 Sep 2021 20:24:33 -0400 Subject: [Elecraft] TVI and More Message-ID: <8C24958D-A9EB-4918-B697-B8AB0C74FF5A@comcast.net> A close neighbor was hearing through her add-on computer speakers what was probably me on 20 meter SSB.

Can anyone tell me about this approach to TVI? That's ancient history. No longer applicable to digital TV. What you have encountered is a classic "Pin One Problem," a designed-in manufacturing error that is nearly universal in consumer electronics of all sorts, including computers, computer accessories, and ham gear. A ham working in pro audio figured this out in 1994, and the pro audio industry corrected the problem within 4-5 years. The rest of the world never got the word. See page 5 in k9yc.com/RFI-Ham.pdf BTW -- by the same mechanism, DC-DC converters built into those speakers are often a very strong source of RF noise in our receivers. 73, Jim K9YC From k6dgw at foothill.net Wed Sep 22 21:39:18 2021 From: k6dgw at foothill.net (Fred Jensen) Date: Wed, 22 Sep 2021 18:39:18 -0700 Subject: [Elecraft] TVI and More In-Reply-To: <8C24958D-A9EB-4918-B697-B8AB0C74FF5A@comcast.net> References: <8C24958D-A9EB-4918-B697-B8AB0C74FF5A@comcast.net> Message-ID: See interspersed...

However, the point about manufacturer responsiveness is well made. I doubt that I will be making any modifications to my TS-890S, though. Apart from having low transmit IMD and good ALC dynamics (including no overshoot) the TS-890S works well with the KPA1500 and similar amplifiers, in part because of the per-band, per-mode power setting and limiting, and the pre-settable tune powers. I understand that Elecraft and several other US manufacturers also implement similar systems, which mitigate a number of potentially embarrassing (or worse) brain/finger problems. Manufacturers such as Icom and Yaesu could usefully catch up. 73, Peter (VK6HP) -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Jim Brown Sent: Wednesday, 22 September 2021 7:37 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Is Kenwood listening?

The last of their HF rigs I've owned was a pair of TS850s. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to p.hall at curtin.edu.au From K1ND at Comcast.net Thu Sep 23 07:59:39 2021 From: K1ND at Comcast.net (Jan) Date: Thu, 23 Sep 2021 07:59:39 -0400 Subject: [Elecraft] DDU for KPA500 ---SOLD Message-ID: The nice DDU by KV5J? for the KPA500 has been sold The K4 transceiver with the KPA500 & KAT500 are being enjoyed Regards, Jan K1ND -- This email has been checked for viruses by AVG. https://www.avg.com From K1ND at Comcast.net Thu Sep 23 08:01:43 2021 From: K1ND at Comcast.net (Jan) Date: Thu, 23 Sep 2021 08:01:43 -0400 Subject: [Elecraft] DDU for KPA500 ---SOLD Message-ID: <5bfd8dbe-ac17-bf2d-94fd-9c0cbf15cd3b@Comcast.net> The nice DDU by KV5J? for the KPA500 has been sold The K4 transceiver with the KPA500 & KAT500 is being enjoyed Regards, Jan K1ND -- This email has been checked for viruses by AVG. https://www.avg.com From K1ND at Comcast.net Thu Sep 23 08:13:06 2021 From: K1ND at Comcast.net (Jan) Date: Thu, 23 Sep 2021 08:13:06 -0400 Subject: [Elecraft] Extra Cables for Elecraft gear Message-ID: <29916b2c-166d-f8bf-c8b8-d99f8561033a@Comcast.net> I have duplicate ~ extra ~ cables for sale (a) Model E850465/PCX4097 with 15pin Male connector labelled Yaesu (b) Model KUSB/PCX0250 labelled PC to FLEX (c) Model KXUSB/PC0151 labelled Tuner to Flex (d) Model E850463/PCX4097 labelled Amp Aux to Tuner Amp You may contact me off the list please 73 Jan K1ND -- This email has been checked for viruses by AVG. https://www.avg.com From rmcgraw at benlomand.net Wed Sep 22 09:23:28 2021 From: rmcgraw at benlomand.net (Bob McGraw) Date: Wed, 22 Sep 2021 08:23:28 -0500 Subject: [Elecraft] KPA1500 Power Level In-Reply-To: References: <6f2e7001d988f150b7f0f39517b3db60@tr2.com> Message-ID: <81f5b597-88d2-53ed-a3f4-7ad887759f6a@benlomand.net> And how did you come to the conclusion of no overshoot? 73 Bob, K4TAX On 9/21/2021 8:48 AM, Salvatore ["Ted"] K2QMF wrote: > I have a Yeasu FTdx5000 and an FTdx101MP. > Both are driving Elecraft KPA1500's. > The driver power is reduced to about 35 Watts on both!?

If you receive this data set be sure you understand that dissipation, heating, and efficiency will be strongly dependent on the complex impedance of the load. I have previously shared test data for my KPA500 but I made no attempt to record drive level and have no data for gain. My measurements were made to explore the influence of output power and loading on PA dissipation. Once you have this data you'll stop believing those who say there is no reason to match to better than 1.5:1. 73, Andy, k3wyc ______________________________________________________________ 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 n8ag at comcast.net Wed Sep 22 22:13:20 2021 From: n8ag at comcast.net (Dave Agsten) Date: Wed, 22 Sep 2021 22:13:20 -0400 (EDT) Subject: [Elecraft] K4 e-mail list?

In tube amps, this is done by a variable pi or pi-L network; with solid state amps, it must be done by a dedicated antenna tuner. The one in the KPA1500 works quite well. Bob and I are both serious contesters (he's much better than me), and within a week of my moving in four miles from him, he made sure I knew how to tune my tube amps. :) We've always been good friends. 73, Jim K9YC From w6jhb at me.com Thu Sep 23 16:48:34 2021 From: w6jhb at me.com (James Bennett) Date: Thu, 23 Sep 2021 14:48:34 -0600 Subject: [Elecraft] P3 Acting Wonky Message-ID: Hope someone can help me out on this one.

One other possibility, what is the minimum operating voltage (Bat min) in the menu is set to? Try something like 9v. With an external supply, using the display function and find out what the unit thinks the battery voltage is (BT). Does the Real time clock work, not set but present and counting? That's part of the charger board. If that's not there, that points to the board. All these different battery tries suggest to me that despite your care about polarity, you could be wrong in some way. Or the unlikely possibility that the unit is defective. However, the above checks will help to understand what is happening.

If your KX3 shows very low voltage, something in your battery holder is wrong.

It remembers what was last used on each band (assuming you are using an Elecraft or Kenwood rig with it). I think it will still remember the last used even in a dumb situation without knowledge from the radio; it just needs the radio support to have "per-band" memory. I could be wrong.

It does not connect unused antenna ports to ground. It does have a GDT and 1 meg resistor to ground on each port, however. When power is off to the KAT500, ANT1 is connected directly to the input port. But you are correct in that it has three output antenna ports. 73, Jack, W6FB > On Sep 30, 2021, at 9:46 AM, Greg Mitchell wrote: > > It has 3 antenna connections, not 4.

Also try not to get fingerprints on the screen side of the lens. Taking the lens off to clean them is a bit annoying.

In-Reply-To: Message-ID: Remember to take it slow and easy. Read each instruction and make sure you understand it. Then do it, check it off on the assembly manual, and go to the next one. It is generally a good idea to inventory the parts so you understand which screw goes where. The small parts can be organized in an egg carton or a ice cube tray. Try to get into the zen of it.
