Re: [Elecraft] Drive Control - K3 and FPA-1500
When you change bands and key the K3/KPA1500 do you see a spike in power and then the power out settles down and is fine till you switch bands? Then you have a spike in power on the initial keying?

Re: [Elecraft] KPA100 failure
Don, You are correct about Schottky diodes such as the 1N5711. Don't just trust using an ohmmeter. They are not typical PN bipolar devices like diodes such as the 1N5811. We actually do some tests as if they are a FET. They are so cheap, that if you suspect an issue, just replace them. 73, N2TK, Tony -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Don Wilhelm Sent: Saturday, January 05, 2019 4:12 PM To: Paul Wilton Cc: Elecraft Discussion List Subject: Re: [Elecraft] KPA100 failure Paul, Sometimes it is just better to replace D16 and D17 than to trust them to an ohmmeter reading. They can be "half bad" - OK at DC, but not at RF. They are 1N5711 diodes. If you have the latest updates, the oscillation is not a concern unless you have a T/R switch problem. If your thermal pads look OK, reuse them. they already have conformed to the slight contours of the heatsink and PA transistor surfaces. Just be sure to put then back the same way they were - they usually stick to the heatsink, so re=positioning them is not a problem. Measure those 22 ohm resistors to make certain they have not changed value due to overheating. 73, Don W3FPR On 1/5/2019 3:55 PM, Paul Wilton wrote: > Don > Thanks for the helpful pointers. > > Although I didn’t build the KPA100, I did have to fix a few items > before it worked.

Re: [Elecraft] Flumoxed
A number of years ago, the SWR on my shunt fed tower kept getting wider and flatter. The feedline buried hardline with an aluminum jacket. The soil here in upstate NY had eaten away the aluminum and produced a goo. When I disconnected all the feedlines to the tower the shield on the 160M feed showed a high resistance. The shield of the other feedlines were providing the return path. So, nice SWR but not a very efficient antenna. 73, N2TK, Tony -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Don Wilhelm Sent: Monday, December 03, 2018 10:07 AM To: don_roberts2...@yahoo.com; elecraft@mailman.qth.net Subject: Re: [Elecraft] Flumoxed Not necessarily - notice the relatively flat SWR (less than 2:1) over a large frequency range (for 160 meters). That normally means that the antenna is acting more like a resistance than a radiator. I would expect the SWR on 160 meters to be low only over a 25kHz or at most 50kHz range of the band. When the SWR bandwidth of an antenna increases, you should be looking for a problem in that feedline, antenna to feedline connections or in the case of a vertical, the ground radial system. One possibility is that the radial wires installed were aluminum - they do not last very long in the ground, for some reason, moles like to chew on them. 73, Don W3FPR On 12/3/2018 9:18 AM, Don Roberts via Elecraft wrote: > Lee, it looks like your inverted L wire has stretched.

[Elecraft] KPA1500 - adding fans
For the heck of it brought my KPA1500 from the basement to the shack desk. Ran a test with 10 CQ’s on 6M with 1K out on FT8. By the time the CQ’s were done the amp temp was up to about 75C. The amp is set so the fan is always on at #1. Added two 4” 110VAC fans in series to cut down the speed and noise and covered the exhaust holes on the top of the amp to extract air. Then I tried with just one 4” fan in the center running full speed. Bottom line there was virtually no difference in the top temp of the amp with these settings. I know, not very scientific. Just seeing if there would be a noticeable difference with adding fans. Time to move the amp back to the basement. I never hear my amps ☺ 73, N2TK, Tony __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com
Re: [Elecraft] Breakers for KPA1500?
Don, I did not in any way suggest using the ground wire for current. But many appliances such as the KPA1500, air compressors, water heater, etc. are 220VAC devices that only require 2 wires plus ground. If you look at the plugs on many of these type devices there are only three prongs - each phase plus ground. There is no need for a neutral wire. Yes, appliances like ovens and dryers where there is a need for 110 VAC besides 220VAC do need the neutral wire, hence the 4-wire plug. I was commenting on the mention below of using 3 wires plus ground for the amp. I can't see how that is necessary for a dedicated outlet for the amp. 2 wires plus ground is quite sufficient. 73, N2TK, Tony -Original Message- From: Don Wilhelm [mailto:donw...@embarqmail.com] Sent: Tuesday, July 10, 2018 9:54 AM To: N2TK, Tony ; j...@audiosystemsgroup.com; elecraft@mailman.qth.net Subject: Re: [Elecraft] Breakers for KPA1500? Tony, While it is possible and safe to use only two wires plug safety ground (Green Wire Ground) for a 240 volt receptacle or 240 volt only device (in-home air conditioner, dryer, etc), it is quite unsafe to split off for a 120 volt supply using one hot and ground - in that case (such as a range that has a 120 volt outlet on it or a 120 volt fan) you MUST run 3 conductors plus ground.

Re: [Elecraft] KPA-1500 Fan Noise
Les, Good advice to check with Elecraft. I believe there are 4 parallel wires for 12V+ and 4 parallel wires for 12V- in the cable. I think most if not all of the 15 pins are used. I believe there is a 12V, 3A supply in the PS box for the RF deck. 73, N2TK, Tony -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of James F.

It seems everywhere I read within Elecraft Documentation is that standard VGA cables should NOT be used. In regards to extensions, I do not know if they all work pin to pin, or that they are meant to just extend standard VGA cables. It certainly would be a way to extend the distance between the K3/K3S and the KPA1500, but still retain the functionality between the two. When the new firmware comes out, and the amp can be controlled by the function buttons on the K3 (PF1-operate/stby and PF2-antenna switch), it would be a sure winner.

I run some high duty cycle modes so I notice the fans kicking into speed 3 a lot when the PA temp gets to 68-70 degrees. That setting does a good job of reducing the temp and keeping it from climbing past 73 degrees. I've changed my min fan speed threshold from 0 to 1 to also help. As you have pointed out 1 is barely perceptible and this helps to reduce the amount of time that fan speeds are on 2+. I'd like to have more separation between the K3S and the KPA1500 RF deck to further distance any noise but the KPAK3AUX cable is only about five feet long, it would be great if that were more like ten feet. Since the cable pin out is straight thru I would imagine a DB15 VGA M-F extension cable would suffice?

If you are doing CW and/or Digital, the noise will only be a factor with the operator. On SSB, the noise will probably be noticeable on the air.

Re: [Elecraft] KPA-1500 Fan Noise - YouTube ?
George, there is nothing like Eimac Orange with a glass bottle. RF sunburn :-) Hey, transistors can run pretty hot too, although they should not melt the solder. Case temp can get to 150 deg C and junction temp to 225 deg C. Yes your finger will burn on the case. And yes, the life of many power devices gets derated based on junction temp. As an example an LDMOS may have an MTTF of 1M hours at 150C and 70K hours at 225C junction temp. JANS space transistors are burned in at 220C and tested up to 125C case temp.

One other thought to keep in mind - solid state amps need a lower delta T than tube amps. Tubes like to run hot - solid state devices not so much. I've seen a tube with the fins so hot that the solder was in globs, while the transmitter was still operating. I doubt any solid state final would have survived that heat. When we installed our solid state TV transmitter, it was a new learning curve in cooling. Both transmitters were 30 kW class AB1. The tube transmitter moved air faster through 3 tubes but had almost 3 times the temperature rise than the specs for the solid state transmitter. Our HVAC company and architect worked on several complex systems with air mixers until we just decided to use wall mounted air conditioners into the room behind the transmitter racks and exhausted to the front of the transmitters. Our solid state transmitter did meet the OSHA limit for 8 hours exposure to noise but just barely. It was very noisy compared to the tube unit. No tube transmitter I have ever used had a temperature shut down on any of the tube stages. 73 George AI4VZ -Original Message- From: Don Wilhelm Only one bit of correction. If the output power is 1500 watts and the efficiency is 50%, that 1500 watts is only half the total power consumed, so there is 1500 watts of power that must be exhausted as heat. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 tony@verizon.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com

Re: [Elecraft] KPA1500 Remote Program
Rick, Was just thinking, I assume that the KPA1500 utility program is like the KPA500 Utility Program in that you can’t run in though LP Bridge. The KPA500 Remote program works fine with LP Bridge. I will still be able to remote the KPA1500 right away to the basement till the KPA1500 Remote program comes out. I will be able to work around that limitation for now. 73, N2TK, Tony From: N2TK, Tony [mailto:tony@verizon.net] Sent: Wednesday, May 30, 2018 7:07 AM To: 'Rick Tavan' Cc: 'Elecraft Reflector' Subject: RE: [Elecraft] KPA1500 Remote Program Hi Rick, Tnx for the info.

Re: [Elecraft] KPA1500 fan noise concern
Hi John, For a long time I had the Acom 2000A sitting on a shelf in the basement right below my feet in the shack. I used their remote box which worked very well. I have a KPA500 on the same shelf using KPA500 Remote which also works very well for controlling the amp. Once the KPA1500 Remote is available I would think it would work as well as the KPA500 Remote program to control the amp. I can't think of a reason to have additional hardware in the shack. I am in the process of removing more of the manual controls to the basement. 73, N2TK, Tony -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of j...@kk9a.com Sent: Monday, May 28, 2018 9:14 PM To: 'Elecraft Reflector' Subject: [Elecraft] KPA1500 fan noise concern I imagine that due to the KPA1500's size it requires a higher volume of air than a large amplifier would. Its small size and weight make it appealing. The Acom 2000 has a control box that is separate from the amp so you really never hear the amp run. I am wondering it something similar can be done with the Elecraft KPA1500, perhaps an option like the K-Pod, so that the noise source is further from the operating position? John KK9A Thanks for the offer, Clay. But we actually did extensive thermal analysis of both the heat sink and fans, tested many different fan types and configurations, and did comparative noise testing of the KPA1500 vs. a number of other amps. As you allude to, there's no magic bullet. Heat must be removed, with various physical and electrical constraints to be satisfied. We have some pretty amazing thermal imaging devices that we use to examine heat signatures of electrical components. These were used during R, which is how we determined that two LDMOS devices were far better than one for heat distribution. We also used it to evaluate the design of our very large/very thick copper heat spreader. On the production line, we review all modules for hot spots during burn-in and make sure the cooling is working perfectly (onset temperature, air distribution around modules, etc.). Of course supplemental cooling of various types has been used with amplifiers in the past. I believe we have a couple of customers and staff experimenting with this idea, and anything that emerges will be posted here. 73, Wayne N6KR __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 tony@verizon.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com

For commercial products, there is IPC-610. That is 400+ pages of descriptions of how to determine acceptability of and build electronic assemblies. It has very clear explanations and lots of pictures and diagrams of right and wrong ways to do things. Unfortunately, you may have to pay to get a copy. There are also a whole series of more specific specification documents for certain operations, but IPC-610 will have most of what you need to know. At least, it is what I look at first. Section 7.3.5.9 allows trimming after soldering if the trimming does not damage the solder. For certain classes of products, a visual inspection at 10X is required. Reflowing after cutting is also acceptable instead of inspection. I believe there are special trimmers that minimize shock during the trimming process. I attempt to follow IPC-610, although my skills may not be fully up to the task. At least I know where I fall short. 73, Mark W7MLG On Sat, Mar 24, 2018 at 10:28 AM, Mark Petrovic <mspetro...@gmail.com> wrote: > While reading through my new K2 kit's control board assembly > instructions, I see that some builders prefer to trim the resistor and > capacitor leads before soldering.

Re: [Elecraft] Resistor and capacitor installation techniques: trim before or after soldering?
Jim, There is actually a way to have your cake and eat it too. Supply the surface mount parts or parts with leads with gold solder pads or leads. Most space parts come this way anyways. These meet RoHS. Prior to mounting on the boards use hot solder pot with SnPb solder to displace the gold (usually a two pot process). But this causes its own set of problems. Many space parts suppliers now offer a hot solder dip service with SnPb (Tin/Lead) solder. Usually the only place RoHS is mentioned is with Europe. But the space community gets a dispensation in regards to using lead solder (SnPb). No one wants to take a chance with whiskers in space. And it is amazing how fast they can grow without an atmosphere. SnPb also now applies to most things that fly real high, not just satellites. It is common practice to use a clear conformal coating over the board. That slows down the whisker process somewhat, especially if you play with topology. Try repairing that board. Most satellites are designed for a 15 year lifetime. So whiskers are a big issue. There are exceptions to that with some of the latest commercial constellations. Microsats (10cm cube (1U) to several "U's") have a very short lifetime (hours to a couple months) usually don't worry about whiskers or radiation issues, so far. It is amazing how long a pound of good SnPb solder will last. It is a good investment. Sorry for all the bandwidth and straying. N2TK, Tony -Original Message- From: James F.

Your note about lead in solder is very apropos.

Among the kits I used to put together were Heathkit and Ramsey, both of whom recommended securing the parts in place by spreading the leads, soldering, and then cutting the wires close to the solder blob, checking for shorts. I assume that goes for Elecraft also, but I have not built any of their radios as kits, so not sure. So how did NASA handle the potential difficulties? Did they have precut parts? Did the tech have to place the part in the board and cut the leads first? If the part was loose, how was it held close to the board, owing to the fact that holding the solder and the iron took two hands? What if the lead length was overestimated and potentially could cause a short? Could the wire be cut and the joint reheated, or did the part have to be removed, recut and reinserted? Just trying to picture the operation.

That makes me suspect that the mic is a cardioid, which is essentially a "half-sphere" directional mic. This generic mic type suffers from proximity effect, which boosts low-frequency sounds that are close to it. Breathe is a low-frequency sound. There is no proximity effect at right angles to the diaphragm of a cardioid, so if you want to continue using it, orient it that way and place it several inches above and to the side of your mouth. You may need to turn up the gain. Several days ago, I posted recommended starting EQ settings. You might want to refer to that post. Or maybe not try to put lipstick on the pig, and take K6LL's very good advice. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 tony@verizon.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com

The Koss looks like the Yamaha except the Koss doesn't use a biased mike element. With the Koss I had to go to FP.H. Also my breath trips the Vox but I have to have the mike gain and Vox gain quite a bit higher than the Yamaha to get similar output for both mikes. I do have a somewhat bassier voice. My transmit equalizer is -16 -16 -7 0 0 +4 +10 0 Any thoughts or comments?

Re: [Elecraft] K3 with N1MM - SPLIT mode
Rick, Good input on the RIT/XIT/CLR info. I may have had the XIT on as I find in large pileups it pays to be offset a little. I will check that to see if it had an impact on going SPLIT when I selected a call in the N1MM+ Bandmap. 73, N2TK, Tony From: rta...@gmail.com [mailto:rta...@gmail.com] On Behalf Of Rick Tavan Sent: Tuesday, February 20, 2018 8:26 PM To: N2TK, Tony <tony@verizon.net> Cc: Elecraft Reflector <elecraft@mailman.qth.net> Subject: Re: [Elecraft] K3 with N1MM - SPLIT mode I think what counts is not the way the target station is operating but rather the way the spotter station is operating. If the spotter had Split engaged, for example to dither its calling frequency in order to stand out in the pileup, then the spot may specify split and cause your symptom, even though the DX station is operating simplex on a single freq. This won't happen all the time - it's a complex interaction among the spotter's rig, operating mode, logging software, Telnet interface, and your Telnet interface, rig, logging software, and settings. I don't think there is anything you can do about it except be aware. (Or maybe you can convince all the hams in the contest to use RIT/XIT/CLAR instead of Split when calling a simplex pileup? Good luck! And RIT/XIT/CLAR can provoke some frequency anomalies of their own.) 73, /Rick N6XI Rick Tavan Truckee, CA On Tue, Feb 20, 2018 at 3:26 PM, N2TK, Tony <tony@verizon.net <mailto:tony@verizon.net> > wrote: Hi Ted, All of the stations that I clicked on the bandmap were operating transceiver.

Re: [Elecraft] Y-Adapter for K3S ACC - KPAK3AUX - KPA-1500
Hi Bob, My KPA500 is in the basement as will be the KA1500. I used to have an Acom 2000A alongside the KPA500. I have a switch in the shack that selects the one output from the K3 to an A/B switch for the inputs of both amps and an A/B switch on the output for both amps to a coax switch. I key the amps in parallel with diode isolation. This has worked well for a long time. I like doing it this way because while the one amp is off I can use the other amp. If I have a problem with an amp all I have to do is turn off the one amp from the screen, turn on the other amp and hit the switch. I don’t have to go to the basement to do anything. Guess I can use a Y-cable with a second KPAK3AUX with both amps in parallel instead of the Y-Box. 73, N2TK, Tony From: rawil...@gmail.com [mailto:rawil...@gmail.com] On Behalf Of Bob Wilson, N6TV Sent: Monday, February 12, 2018 3:48 PM To: N2TK, Tony <tony@verizon.net>; Elecraft Reflector <Elecraft@mailman.qth.net> Subject: RE: [Elecraft] Y-Adapter for K3S ACC - KPAK3AUX - KPA-1500 If you want to connect both amplifiers to the same K3, one on Antenna Port 1, the second on Antenna Port 2, just connect a second KPAK3AUX cable between the KPA1500 and the Y-BOX.

Older warts are often available at second hand stores and flea markets. $1 is the going rate. In general, linear warts are much heavier than SMPS units, so that's a good first check. A better one is to plug it into AC and hold a portable radio next to it tuned somewhere near 2 MHz (like the top of the AM BC band). If you hear hash, it's a switcher.

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

Re: [Elecraft] Signing "/QRP"
Don, You are so correct about affecting the rhythm. One other issue happens when signals are very weak. "/QRP" ads four characters more you need to copy. If after several tries I don't feel like I got the entire call correct I don't log it and I move on. If the QRPer is running and wants to use "/QRP", that is fine. When the QRPer is answering a CQ, especially in a contest, don't hang the "/QRP" on the call. The running station may not have good copy on you. The "/" may mean something else other than QRP. I have nothing against QRP. Each to their own as to what they are trying to accomplish. That is cool. I am just saying, try to help so the QSO is valid and you are in the log. 73, N2TK, Tony -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Don Wilhelm Sent: Wednesday, July 26, 2017 8:25 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Signing "/QRP" I recall my first contact after getting my KX3. It was on SSB. I did not indicate my power level until well into the contact, and the other operator said "I cannot believe you are running only 10 watts." So much for the /QRP signing, you can make contacts, and that is what counts. It all depends on the attitude of the operator on the far end of the QSO. There are several who will ignore any operator who signs /QRP, so in general, I would discourage doing so. OTOH, if you are looking for only other QRP stations, then by all means use it. For brevity of exchanges, I would discourage it in contests and operations like Field Day - the added suffix will only interfere with the receiving operator's 'rhythm". 73, Don W3FPR On 7/26/2017 8:10 PM, Charlie T, K3ICH wrote: > Ultimately, what is the real purpose of signing /QRP ??? > > The only answer I can think of translates to "give me a break, I want > special treatment". > > I've operated many times with a barefoot KX3 and now a KX2 and NEVER > signed /QRP, or even mentioned the power level unless the contact > asked what I was running. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 tony@verizon.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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 arch...@mail-archive.com

Re: [Elecraft] Linear thoughts
Most everything desired has already been mentioned. Use SPE amps as a baseline for features and learning curve. - QSK Preferably PIN diodes - Remote capability like the KPA500 but with more monitoring capability so I can put the amp in the basement alongside the KPA500. - SO2R capability built in - 2 rig inputs - 4-6 antenna outputs programmable and easily switchable - Low distortion LDMOS - single ended or two for push-pull. Max of two MOSFETS. - Switching supply naturally - Optional built-in tuner that can handle at least 3:1. Amp without tuner can handle at least 2:1 SWR without fold back on power. - 1500W key down for digital on 160-6M - Separate or combined amp/PS depends on size and weight. - Amp/tuner tracks K3 receive for pre-tuning. - some form of pre-distortion control to keep the amp clean at full output. 73, N2TK, Tony -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Eric Swartz - WA6HHQ, Elecraft Sent: Friday, March 17, 2017 1:07 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Linear thoughts Interesting discussion.

Re: [Elecraft] list submission, using ham radio deluxe and logic with k3 and a laptop with only com3
Max, Tnx for the info. When I get home will check out the Acom/LP-Bridge interface. I have both K3’s set up similarly – one set of settings for CW and one set for SSB, which the K3 remembers. I have not changed them in a long time and see no reason to change them frequently. Both rigs are set up for contesting and DXing. LP-Bridge gas been very reliable. Looks like I may stay with it for now once I get the Acom setup with it. Yes, once I send a dit the Acom will setup, but I like the idea that it is tracking my receiver. 73, N2TK/NP2 (KP2M), Tony From: M. George [mailto:m.matthew.geo...@gmail.com] Sent: Thursday, March 02, 2017 8:38 PM To: N2TK, Tony <tony@verizon.net> Cc: Elecraft Reflector <elecraft@mailman.qth.net> Subject: Re: [Elecraft] list submission, using ham radio deluxe and logic with k3 and a laptop with only com3 Hi Tony, first off I can help you with LP-Bridge sending data to your ACOM 2000a. In LP-Bridge, the read only outputs are hard coded to the kenwood protocol at 4800 baud. So you can use LP-Bridge to get your ACOM 2000a to track your K3 if you set the ACOM 2000A to Kenwood on the radio interface. I had this configured and working on Jim's W7CT's setup a few months back. I exchanged a few emails with Larry N8LP and he pointed out the hard coded Kenwood / 4800 baud protocol on the output option in LP-Bridge. Like you I didn't get excited about Win4K3Suite at first and I too saw the RX eq settings reset. But after thinking through it, I love the RX eq settings being controlled by Win4K3Suite now. There is no way to do that from a K3 macro as far as I know... on the RX side. So with Win4K3Suite, you can store RX eq presents and switch between them on the fly AND you can change the RX eq settings in real-time and hear the change, you can't do this via the Config menu. It does take a few seconds for Win4K3Suite to manipulate the RX eq settings because it's doing some tricks to change the settings on the fly. The reason Win4K3Suite resets the eq settings is because there is no way to read the settings from the K3 to store them in the first place... so it resets the settings for TX and RX eq at start up and then once you change them in W4K3S and exit Win4K3Suite it stores them in the Win4K3Suite config on disk... so then the next time you start up, it restores the settings to your K3. I was annoyed by this until I read Tom's FAQ here: http://va2fsq.com/faq/ Then the light turned on. There is no way to read settings from the K3 eq, so to externalize this, Tom is working around that limitation. Once you set them up in W4K3S you are golden. And it's a major bonus to changes those on the fly as I have described. BTW, I'm just a happy user of W4K3S if you are wondering... I have no reason to try and tout it other than I have been happy with the updates and support. Even if you don't use the spectrum display in W4K3S, based on my many year experience with LP-Bridge and NaP3, I still think it's well worth it on how it shares the K3 CAT data. It has been totally reliable too... Anyway, give it another try and play around with the multiple and dynamic UI settings for the eq in your K3.

It is pretty good and the price sure is right however! I have switched to Win4K3Suite with com0com for the CAT sharing of the K3(s) and it has been rock solid. As others have mentioned, you can share the K3 CAT interface with up to 4 other applications and the lastest version of Win4K3Suite also adds 3 or 4 (off the top of my head) read only interfaces that you can use... i.e. like an SDA100 SteppIR controller or an Amplifier that will track the transceiver frequency. VSPE looks pretty good, but the license feed for the signed 64 bit version is ~$25 and that gets you half way to the cost of Win4K3Suite... Win4K3WSuite in and of itself is really nice. The more I use it, the more I like it... for example, pre defined RX EQ settings are so nice where you can just push a button and change the EQ settings on the K3 in a few seconds and if you are tweaking the EQ settings, you get to hear things live without having to leave the Config menu. Anyway, I'm really like the spectrum display to in combination with an LP-PAN2. It's become the replacement to NaP3. It's all together just a much more reliable solution than LP-Bridge and NaP3 IMHO. I can't live without my LP-PAN2 by the way... but now I no longer need to deal with LP-Bridge and Win4K3Suite starts right up with no delay where the com0com ports are created when Windows 10 starts up.

Re: [Elecraft] Vacuum Relays and 30 WPM QSK
For years with slower keying rigs I would key the amp which would key the rig. This saved relays. When Kenwood came out with the TS-930. 940 etc. they had very nice QSK. But it was best to use a Mosfet or something to key the amp rather than the internal rig's relay which was too slow. I used to key my 2000A then key the rig till I got my first K3. Now I key the K3 which keys the amp. If I am running I do not use QSK. It gives my ears a break. But if I am hunting and pecking I always use QSK and wish more did also to minimize QRM. I have no complaints after 17 years of use of the 2000A and only having to change the vacuum relay once. A very small price to pay for the luxury of QSK. And changing a vacuum relay is usually a lot cheaper than changing the switching diodes which failed in quite a few Alphas. Next time you have a vacuum relay fail cut it open to see if the contacts are burnt from hot switching. 73, N2TK, Tony -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Brown Sent: Monday, February 27, 2017 11:28 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Vacuum Relays and 30 WPM QSK On Sun,2/26/2017 3:04 PM, Guy Olinger K2AV wrote: > But even though the K3 is cycling TX/RX very fast the 8410 is not > banging the vacuum relay to death trying to follow 30 wpm dits. 30 wpm > QSK*does* significantly shorten relay time to failure.

I concur Ed. On SSB when running stations I will only mess with the HI CUT. Wil crank it down to 2.1. The intelligibility is still good. Sometimes I forget and just leave it at that setting for the entire contest. It makes it so you can squeeze in between two other strong stations so that all three can keep running.

If we all agreed on all the CONFIG parameters they wouldn't need to be variable! One that I particularly disagree with is how to narrow the IF bandwidth in SSB mode. The recommendation to narrow the bandwidth and then lower the IF Shift is unnecessarily cumbersome on SSB. After going through these gyrations, you'll find that the LO CUT is where it was before you started. So, all that needs to be done to narrow the SSB IF bandwidth is simply decrease HI CUT.

Re: [Elecraft] K3 - stuck at MCU LD we upgrading software
Hi Jimmy, Tnx for the info. I have a 35A switcher that loafs along. As I never have both K3's transmitting at the same time I am not taxing the supply. W3FPR got me on the correct track. In your case, di d you check the voltage on the K3? Maybe you had a problem with a connection in the power supply? Down in the Caribbean periodically we have to take apart the Astron linear power supplies and clean the contact surface on the two bolts feeding the 12V output. They develop a little bit of resistance that drops the voltage under a load. 73, N2TK, Tony -Original Message- From: James Walker [mailto:jimmy.wal...@outlook.com] Sent: Saturday, January 28, 2017 12:58 PM To: N2TK, Tony <tony@verizon.net> Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 - stuck at MCU LD we upgrading software Tony, I used to have this problem all the time. It was maddening. I never knew if the rig was going to turn on. It was always necessary to restart my computer to get my K3/100 to talk to the app that resets the firmware. I had several suggestions to fix the problem. The one that proved most helpful was to get a different power supply. I was using a big Astron supply feeding into a Johnson power strip. Several devices ran off the power supply. It should have been able to supply plenty of power for everything because the other devices were low wattage users like a keyer. Anyway, I had a smaller Anstron device that was once used with a 2-Meter radio. It was fully capable of 100 watts. I hooked it up and the rig as a dedicated supply and it has worked perfectly ever since. You may have a different problem than me but that’s my story.

Re: [Elecraft] Please do a KPA1500
During mediocre conditions there has been more than once on 80 and 160M the DX could not quite get my call correct with the KPA500. Once the Acom 2000A timed out they had no trouble copying my call. Most of the time I operate the K3 barefoot. When I need more oomph I turn on the KPA500. If conditions are not good I turn on the Acom. There are times the difference between 600W and 1500W can make the difference between a QSO and no QSO. It would be nice to have a 1500W S-S amp in the basement alongside the KPA500. Any amp I would buy needs to be able to be controlled remotely like the KPA500 and the Acom. The only real advantage to me switching from a tube to a solid-state amp would be the timeout thing. During a contest and when a DXpedition is going, then I just leave the Acom on.

Re: [Elecraft] K3: KFL3C-200 filter
I think we are talking about different types of QRN. This evening the noise level is way down. My Pennants seem to be quite directive. Of course the W1FV array still does not work. The BOG is hearing quite well but no directivity at 220'. Will try shortening it. I was chatting with AA1K a little while ago. He does quite well down in DE with his array of receive and transmit antennas on 160M. He was saying weird propagation and noise this past weekend too on 80 and 160M. Oh well, probably see more of this with the low sunspot numbers. SW3LPL had a good explanation of this the other day. 73 N2TK, Tony -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Eric NO3M Sent: Wednesday, November 30, 2016 2:13 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3: KFL3C-200 filter We may also be referring to different types of QRN.

APF doesn't seem particularly useful on very weak signals when a certain amount of QRN is present either.

Hi Barry, Tnx for the info. Yes, I do like my 200HZ filters. I have one in each rig. When running split when bands are crowded I can have the VFO A width down to 200HZ. Usually I have VFO B wider. I was trying to find out if the new 200 HZ filters had any advantages over the older 200 HZ filters that you could hear.

Re: [Elecraft] Cold K3
Hi Ed, We routinely test military/space parts at -55C to +125C. The parts are under voltage and monitored throughout the range. Many of the failures at the very low temp ranges may not be permanent. As the temp is raised the device most of the time functions properly again. There are some anomalies though. We have seen some memory devices work fine at -55C and then lose bits around -40C. And then work fine as the temp rises again. At the high temp end there is greater chance for permanent failure. So, very cold temps can be an issue with any of our gear, especially considering we are using commercial parts. Test temp ranges for semiconductors; Commercial - 0C to +70/80C Automotive - -40C to +125C Military - -55C to +125C 73, N2TK, Tony -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Edward R Cole Sent: Thursday, October 06, 2016 12:43 AM To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] Cold K3 Dick, The KX3 will not see those extreme cold temps. Where we live it rarely drops below -15F and typically is 0 to +10F at night in winter. The KX3 has a RAM bracket in my truck so it might sit outside at night. I was wondering how it would react to being powered on at down to -15F. Truthfully it might not ever face that as I have remote start for the truck to warm up for winter driving so the cab might reach +20 or higher before I would use it. A few miles driving and the cab should be +50 to 60F which is comfortable wearing a winter coat. More than likely I would just bring the radio inside at night if planning to use it the next day. My experience with the TS-180S was that the cold effected the LCD screen so operating was not possible until it warmed. That experience in 1986 was the coldest I have seen in my 36 years up here in AK. Quite possible the temp dropped to -80F at night (-78F is the official record for AK). Fortunately at extreme cold the air is completely calm most of the time. Dog teams coming into the checkpoint reported -45F on the ridge tops but with 30-40mph winds which would feel much colder than what we were down in the lake valley. The coldest I have experience at home on the Kenai Peninsula is -35F and that was nighttime so I stayed inside near the wood stove. I now live in a modern home with force-air natural gas heat and its +67F to +71F year round. Radio gear is std in all vehicles used at Prudhoe Bay on AK's "north slope" but either they leave the engines run continuously or they are plugged in with electric heaters on the inside keeping the interior from freezing. Ever climb into a suburban when the seats are -40F and hard as a rock (a very cold rock)? In fact the seats split apart if allowed to get that cold. Most repeaters up there are enclosed in warmed buildings and only antenna and coax outside. I had fun up there in Nov.1980 installing MOT radios in heavy equipment that was parked outside (it was only -15F so my bare hands took a punishment). After a couple days one of the operators showed me how to start up the engines and I got a little warmth inside the cabs (+15 vs -15). I was young (36) and adventurous - making $6500 in three weeks working 18-hour days didn't hurt, either. 73, Ed - KL7UW From: Richard Fjeld <rpfj...@outlook.com> To: "elecraft@mailman.qth.net" <elecraft@mailman.qth.net> Subject: Re: [Elecraft] Cold K3 On 10/4/2016 7:16 PM, Edward R Cole wrote: I've not tried running my K3 at outside temps, Hello Ed, I would caution you against trying your K3 in those temps.

I didn't notice if it does. Our club left a repeater in an unheated enclosure one winter. I would estimate it wasn't much colder than minus 30 degrees F. at that location. (To clarify for others, this is 30 degrees F. below zero.) I have seen what the multi-layer circuit board looked like. More specifically, the thru-the-hole solder connections from one layer to another were cracked. Maybe it was the type of solder used??? I'm sure circuit designs have changed since the first solid state rigs I described in the cold. LCD screens hadn't been heard of yet. I'm surprised they don't freeze and get damaged in your temps.

I too have built my own enclosures with similar techniques. A couple of my projects can be seen here: http://sadxa.org/n7ws.html#amp Although at the time I had access to a prototype workshop, I have done similar work at home with comparable results. If possible, I avoid bends. In all of this stuff I used 0.062" 6061-T6 material so it wasn't going to bend anyway. The harder alloy drills like a dream. For all of the corner joinery I used 3/8" square stock, 8/32 threads and stainless steel screws In the protoshop, I had access to a shear but all of the sheared edges were still smoothed by hand. I had a granite surface plate and used a vernier height gauge for layout so similar parts were interchangeable. In the home shop I lay out as carefully as possible and match drill on a drill press. Most people can't tell the difference. With a lot of elbow grease a hacksaw works, although after a lot of furniture building and finish sanding, I needed rotator cuff surgery so I don't do that anymore. With extreme care and I do mean extreme, a carbide toothed blade on a table saw will cut aluminum if it's thick enough and the blade has fine enough teeth. Otherwise I use a bandsaw, which is always safer, if less precise. In the protoshop I had access to chemical dip baths for passivating the aluminum, silver plating the RF parts and a panograph engraver for panel lettering. Silver looks nice, but is highly overrated as an RF conductor.* In the home shop, before the un-elected bureaucrats in DC decided we were too stupid to handle lye (judging by the electorate they may be right), I would etch aluminum in a lye bath, rinse and neutralize with vinegar and a final water rinse. This would yield a nice satin finish. The best I have found since is oven cleaner. Another finish, if you like the look, can be had by using a random-orbit sander Play with the grit until you find something you like. Sanding it wet with a little cutting oil can be fun, albeit messy, too. Tube amplifier still have their virtues and, along with antennas, can be great roll-your-own projects that can work better than what you can buy.

Re: [Elecraft] The 1500 watt amp
I remember seeing the KPA1500 at Dayton heating up the building. I reached for my credit card but was told not taking orders. Bummer. Today I have a KPA500 and an Acom-2000A (very early one) sitting on a shelf 7' off the floor in the basement. Literally right below my feet here in the office/shack. Keeps the heat and noise downstairs. Both track the K3. So when I key the amp it is on freq and ready. I have two switches between the pair of K3's - one to select which K3 and one to select which amp. Most of the time both amps are off. I find 100 W is usually enough. But in a decent pileup I will turn on the KPA500. For DXpeditions like VK0 and FT4, especially on the low bands, I can get in and out more quickly with the Acom. For contesting the Acom stays on the entire weekend. This setup also gives me backup in case one of the amps fail. Also give me more watts on 6M. Someone mentioned about you got to hear them to work them. And I agree money should be first spent on receiving - equipment, antennas, coax, receive antennas, etc. But once you have optimized as much as you can because of land, money and other restrictions, an amp is a nice way of helping you in a pileup to work a station you can hear. And especially on the low bands going from 500 to 1500 W may make the difference from working and not working a station. I still remember the one morning I heard Zone 19 on Topband for my first and only time at my sunrise. Unfortunately I did not have the KPA500 then. Only had the Acom. But the Acom was off. While I waited for the Acom to heat up I tried calling the UA0 with 100W. He knew I was calling him but he could not pull out my full call. By the time the Acom cycled ON, the UA0 was down in the noise.

W4TV and W3FPR got me down the right path. I forgot that it is a pulse on RS232 pin1. Got the scope out and it is fine. Thanks Don. Got to get me one of those small, lightweight scopes. I had both transistors in the RS232 shell (FSK keying and PTT) and when I opened the shell it looked like I had not hooked up the transistor to pin4 of the Acc plug. Actually I must have cold soldered the lead and it broke free after several years. When I first looked at the lead it seemed I had unsoldered the lead and insulated it.

[Elecraft] K3 - MMTTY interface for FSK
I am having brain freeze. I must have changed something but not sure what. Both K3's had been working fine on FSK using MMTTY for years. I can still receive fine, but I can't transmit on either. I am using LP Bridge which is talking fine to either K3. When I hit Xmit in MMTTY the program shows it is sending, but it does not key the K3. All along I have been using COM 1 on my PC for FSK keying. I have been using pin 3 to Pin 1 on the Acc K3 socket. I have not used Pin 7 (PTT) to Pin 4 on the K3. When I measure voltage on Com 1 pin 3 it is -9V. When I hit Xmit in MMTTY it stays at -9V. MMTTY is setup as follows: - Misc tab - COM-TxD (FSK) - TX tab - Port Com1. - I am not using Radio Command K3 - PTT-KEY is OFF-OFF. One K3 has KIO3A using RS232. The other has KIO3B using USB. Also if I ground pin 4 on the Acc socket it does not transmit. Tried another Com port and made the change in MMTTY but the same result.

I hadn't used the 2nd receiver really much at all (only had the rig a few days) and was hesitant to play with it until I learned a little more about the rig in general. Anyways - an AHA! -moment. The IF Noise Blanker actually works pretty well on the 2nd receiver. So, that leads me to believe that there's something about the primary rx that is not quite right. Are there two KNB3 blanker boards in an early K3 with two receivers? Can I revert the firmware back to 4.83 (I saved it to a folder before upgrading to the latest) and see if somehow the blanker was maybe shut off, then turn it back on, then re: upgrade the firmware? I just knew there was something up! BTW, it was only the first day I had the radio that I heard relays clickity clacking when I had the NB engaged. Now I just transmit once or twice, and the NB letters flash. (no relay noise) 2nd receiver NB seems fine. Is it easy to find the KNB3 board(s) ? Tnx to whoever it was who asked about that.(kudos and give yourself a pat on the back) - you were the only one in 25+ ops to suggest that).

Re: [Elecraft] Stripping toroid leads
Is there a recommendation on small solder pots?

In upstate NY (65 miles North of NYC) there is a strong carrier about s9 +15 with lots of ups and downs.

Re: [Elecraft] K3 KIO3B - FSK - stereo
Thought I had it correct. One issue when comparing the onboard Codex to the outboard M-Audio Delta 44. I am running two versions of MMTTY at the same time. AXETTY set up for main receiver and using left MMTTY channel. Second MMTTY set up for second receiver and right channel in MMTTY Line out on K3 - 001 With M-Audio Delta 44 Using Line 1/2 - Left Channel Recording Level - 33 AXETTY - Main K3 receiver decoding fine all the time MMTTY - Second receiver - nothing decoded with SUB off. Decoding fine with SUB ON. I like it this way Using Codex and Cable from Delta 44 still plugged in - it doesn't matter if the other end is plugged in or pulled out of the Delta 44. Using Codex Microphone Recording level - 3 AXETTY - Main K3 receiver decoding fine all the time. MMTTY - Second receiver - nothing decoded with SUB off. Decoding fine with SUB ON. Using Codec and Cable from Delta 44 removed from the K3. Using Codex microphone Recording level - 3 AXETTY - Main K3 receiver decoding fine all the time. MMTTY - Second receiver - with SUB off decoding strong signals (>s8) from the Main receiver. Second receiver RF gain has no effect on reducing the signal on the second receiver decoding. The RF gain on the second receiver works fine as it should with the SUB ON and decoding is fine. The problem is that if I am listening to a strong signal on the main receiver and operating split mode and the receive signal in the second receiver is not strong, the decoding is a combination of both signals scrambled on the second receiver. I use the second receiver to find out the pattern and where the DX is listening. Any ideas why the crossover with the Codex? If I reduce K3 Line out any more or reduce Codex microphone recording level any more there is no signals on either receiver. Interesting that plugging in a jack in the K3 Line out solves the problem. Tnx for any feedback. Sri about all the recent KIO3B posts.
