Not quite: you would also need a new KPAIO3A interface board - and even then, it would only be a partial upgrade. My very early K3S/10 was probably the first to undergo a comprehensive 'module migration' in the wild (5000 miles away from the factory). Elecraft's support was exemplary - as ever - but we discovered that the older KPAIO3 does not function correctly with the K3S mainboard. It does not correctly control the relays and the fans, so it fails the PAIO TST procedures. When the KPAIO3 is replaced by a KPAIO3A, then the KPA3 does become compatible with the K3S and will function much the same as it did in the K3. But migrating a KPA3 into a K3S can only ever be an *incomplete* upgrade. As Joe has already pointed out, it does not include many of the other improvements that Elecraft made in this area of the K3S - not only the increased number of power pins but also the KPA3A itself, which is a completely new design using power MOSFETs. So even though it is possible to migrate a KPA3 into a K3S, the result can never be a true K3S/100. Therefore it isn't surprising that Elecraft does not recommend this procedure, and does not offer it as part of the factory migration service. 73 from Ian GM3SEK >From: elecraft-bounces at mailman.qth.net [mailto:elecraft- >bounces at mailman.qth.net] On Behalf Of hawley, charles j jr >Sent: 31 March 2018 21:22 >To: Joe Subich, W4TV >Cc: elecraft at mailman.qth.net >Subject: Re: [Elecraft] Migrating a KPA3 POWER module to a K3S > >Thanks.

However, initial setup of the rig's USB port by the PC may cause pulsed or continuous activation of the transmitter. This can happen if the computer is turned on after the K3S, or if the USB cable is not connected. There is now a "Safe" mode (the default) which disables PTT-KEY transmit until the K3S receives a command via USB, such as a read of the rig's VFO frequency. To turn on safe mode on/off, go into CONFIG:PTT-KEY and tap '1' to select "USB SAFE" or "UNSAFE". Exit the menu and turn the K3S off/on. Applications that use PTT-KEY via USB but never send commands may require "UNSAFE" mode. In this case, unwanted transmit can be avoided by turning the PC on before the K3S. * CANCELLING UNEXPECTED PTT-KEY ACTIVATION: If an external source (usually a PC) activates PTT or KEY unexpectedly, you can cancel transmit by tapping the XMIT switch. This will show ERR KEY or ERR PTT on VFO B. Once the PTT or KEY source as been removed, transmit will be re-enabled. If the cause may be unneeded PTT-KEY activation via the USB port, go into the CONFIG:PTT-KEY menu entry and set the parameter to OFF-OFF. However, if use an FTDI USB-to-Serial adapter on Windows with other Elecraft radios or devices, the FTDI drivers provide an easy way to disable the search for a serial mouse or legacy analog modem on the serial port, and this prevents unwanted RTS/DTR "key down" activation at boot time. This works with recent KUSB adapters or homebrew external CW or FSK keying circuits on virtual serial ports that may be connected to your radio (K3, K3S, KX2, KX3, etc.). 1. Open the Windows *Device Manager* (shortcut: Windows Key + R (run): devmgmt.msc) 2. Expand *Ports* 3. *Right click* on the virtual COM port defined by the FTDI USB-to-Serial Adapter 4. Click *Properties* 5. Select the *Port Settings* tab 6. Click the *Advanced...* button 7. Under *Miscellaneous Options*: 1. Uncheck *Serial Enumerator* (default is checked) 2. Check *Disable Modem Control at Startup* (default is unchecked). This should be the only option in the list that should be checked. 8. Click *OK* to close the Advanced Settings dialog 9. Click *OK* again to close the Serial Port Properties dialog As far as I know, only FTDI's USB-to-Serial drivers provide options to disable this legacy behavior on Windows that causes RTS/DTR to be activated at boot time. 73, Bob, N6TV On Thu, Mar 29, 2018 at 5:11 PM, Don Wilhelm wrote: > Bill, > > If you have updated the K3 firmware in the last few months, it does not > make any difference whether the K3 or the computer is turned on first. > The K3 now has a SAFE mode that disables DTR and RTS until it receives > some command like polling for frequency, mode, etc. from your software > application. > > You can go into the K3 CONFIG menu for KEY-PTT and turn it to unsafe if > you have devices that monitor the RS-232 bus and do not issue any commands > (SteppIR controllers for one instance). > > Look at the firmware release notes for the past 3 months. > BTW, the firmware release notes should be considered an addition to your > K3/K3S manual.

Yep. The KX3 is also highly compatible with external battery packs, something as simple as six AAs in a holder that plugs into the power jack. LiFePO4 packs sold by Bioennopower have also become quite popular. They come in a wide range of sizes/capacities, and are much lighter weight for the capacity they provide. For all day 100w operationat a rare mountaintop 6M grid that is in deep shade and requires a 3 mile hike up a 1,000 ft trail, several of us have bought 20Ah batteries, cost about $200 and weighs 5.5#. Much smaller packs are available. A 3 Ah pack costs $50 and weighs 13 oz. Remember that the KX3 draws less current for the same power output when run from a higher DC voltage, and LiFePO4 batteries provide 13-14V for most of their discharge curve. 73, Jim K9YC From cozzicon at gmail.com Sun Apr 1 14:29:11 2018 From: cozzicon at gmail.com (Michael Cozzi) Date: Sun, 1 Apr 2018 14:29:11 -0400 Subject: [Elecraft] The new KX19 In-Reply-To: References: Message-ID: <97a1d7af-02ab-feaf-475e-f999154f4d02@gmail.com> ???

They are not cheap and not found at your local electronics emporium. As I recall, I paid about $55.00 for mine. I have one from a small German factory; it has an LCD for each battery and gives various useful info about each battery. It does give up on some but saves a lot of others. For me it was worthwhile; there are lot of AA and AAA batteries in our household besides Ham Gear (GPS Receiver, High powered camera flash, grandkid's toys, telephones, LED flashlights, etc.).

After a little K3 Manual study: page 55 for MIC SEL options I chose to try using the 3.5mm rear mic jack; ModMic comes with stereo 3.5mm so questioned if it would work in mono jack. tip = cardiod element ring = omni element base ring = ground I checked on-line to find that both require 1-10v bias so 8v bias from K3 works great MIC SEL: rP.L biAS tap 2 to toggle bias on tap1 was left in Low How to key radio: rear PTT IN (female RCA-Phono) not in use with my radio Alt key; My Heil CM10 desk mic has a breakout with 1/4-inch phono receptacle for a foot switch - used that (works whether front or rear mic selected) So I key the radio, observe ALC and RF power on a Bird and va la there is modulation. Level is higher with omni element selected. No "on-air" quality test at this point. I attached the boom mic to my "old trusty" SONY MDR-V600 stereo headset. Neat part is boom is held with a strong miniature magnet so easy to remove mic and store In nice foam zippered case supplied with the ModMic. Also has mic mute button and extension cord, spare stickered bases and cable clips. Next to test with KX3 (I will need four ring wye to two 3.5mm jacks extension - I believe obtainable from Elecraft).

I have the K2/10 with the KAT2 in one box.? I built the KAT100 and KPA100 in the EC2 enclosure.? With the K2/10 connected to the KPA100/KAT100, I hooked up an antenna and initiated a TUNE on 40 meters.? It started tuning and in the middle of the tune, everything shut down as if I had turned the power swtich off.? I tuned the power switch off and back on again and now it will only power up for about a second and immediately shut down again.? I disconnected the K2 from the KPA/KAT box and with nothing connected but power to the K2/10 it still does the same thing. I disassembled it and checked Q7 and Q8 which do not appear to be shorted.? The collector voltage on both initially reads 10.8 volts at power up until it shuts down and then drops to about 0.8 volts.? The base voltage on both of them is at about 0.55 volts.

If you find the same on your machine, simply quick uninstall, then go to the top tool bar and click on action and scan for hardware changes. The snippet tool won't let me copy to point it out to you. See if that doesn't do it. So, to summarize, Device manager, click on the Universal Serial Bus Controllers, right click on marked USB devices marked with a fault indicator and then uninstall each of them, then go up to menu and then scan for changes. That should do it. Of course, you have to select the correct port when using the utility, and try each one to be sure you have the correct port! 72 & 73, Bill K9YEQ FT?er for K2, KX1, KX3, KXPA100, KAT500, W2, etc. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Ed Gilliland Sent: Sunday, April 1, 2018 5:09 PM To: Dick Dievendorff Cc: Elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA-1500 s/n 56 I replaced the USB cable with a known good cable, no help.

Many folks have had this issue with Macs, including me. One way is to use a USB?>Thunderbolt adapter; it appears that several years ago Apple changed something in the way USB2 is handled in the OS and the result is audio occasionally getting sent to the internet speakers instead of the USB Audio CODEC. That adapter thing is how I resolved it on my MacBook Pro. Another way, and the one I use on my iMac that does not have a Thunderbolt port, is to bring up the MIDI application and set the USB Audio CODEC input and output to 44100 Hz instead of the recommended 48000 Hz. That has cured it for me and many others. You could also try that on your MacBook instead of using an adapter - up to you.I like the adapter method, as it frees up my USB port for other ?stuff?. 73, Jim / W6JHB > On Apr 3, 2018, at 8:53 AM, Craig Taylor wrote: > > I am running a MacBook Pro with my K3.

Use regular 120V outlet. I run the red transformer tap to keep my transmit HV above 60 at full 500 output. The yellow tap did not provide sufficient voltage on transmit. Thus the red. I have a whole-house surge protector just outside my main breaker box. Here is my issue in summary. The "60v supply over limit" fault does not "throw" any hard or otherwise noticeable fault on my amp during operation. That fault is supposed to flip the amp from operate to standby I'm told. Separately, that fault, if amp is in standby, is supposed to power off the amp, I'm told. My amp shows this fault in the Utility Fault Table, but I'm not aware of it, unless I look at the Table and see it. It operates as normal, pumping out full power, but never shows externally as a fault on the display, nor exhibits the standby flip or power off, that the written manual and the support guys tell me it should. So I know what it *should* do, but after operating it like this, I know what it *does/does not* do. Thus, I seek any input or advice. Should I keep operating per normal, since this fault doesn't actually change my daily operation as noted. Given that, will I end up harming the supply after passage of time? Should I assume I have a faulty Fault Table in the utility on my Mac? Should I, since it's under one year old, and was factory assembled, return it for inspection under a warranty? I just need thoughts on this from the group. Anybody out there ever experienced this?

The 65 to 85 volt range is to be determined with the amplifier turned on, but not keyed and certainly not running at 500 watts. Do as the manual indicates and measure you AC Mains voltage and select the tap which corresponds to that voltage (chart on page 6 of the Owner's manual. If you cannot get 500 watts out after doing that, the likely reason is that your line voltage is dropping with load. Have a qualified electrician wire a dedicated outlet in the shack with #12 or larger wire. 73, Don W3FPR On 4/3/2018 3:13 PM, Robert Jackson wrote: > My KPA500 was purchased new in July 2017.

Everything has been working fine until I had to reset my router, a Apple Time Capsule. Now the remote rig just beeps at me and does not turn K3S on. Documentation is difficult to find on exactly how to configure a Time Capsule to work with the remote rigs. I contacted Elecraft technical support but they referred me to manuals on remote rig and their K3 mini manual but I find little in the way of Mac support with a Apple router. Elecraft says this is beyond their networking knowledge. I believe I have set the port forwarding up correctly but since documentation is limited, I am not sure I have done so correctly or have missed something. Hopefully someone out there has theirs up and running with Apple hardware and can advise or Elecraft can help better than they have. 73?s From toms at xmission.com Wed Apr 4 09:15:33 2018 From: toms at xmission.com (Thomas Schaefer) Date: Wed, 4 Apr 2018 09:15:33 -0400 Subject: [Elecraft] Any KPA1500 received that were ordered after 1st day?

That is exactly what I needed. As the point of my message seems to have been lost on many responding, allow me to clarify. I realize no amount of discussing where the amp is will get it here any faster. That was not the point. I simply suggested it was a question I had every time a new ?Amp received? message was posted. It was to satisfy my curiosity which several hams are doing. I also had a reason to ask in that I help maintain a contest station and a remote station. The amp factors into our plans so I was trying to get a sense of projects coming up towards the Fall and Winter contest season. If we are already ploughing through the orders from the second week, that tells me something different for station planning than where we are now about how many minutes into the first day. Amp #52 was ordered 15 minutes after. Amp #56 was ordered 43 minutes after the ordering started. And yes, I know that is not necessarily linear as ordered came in from multiple channels. Lastly, I would rather wait for a great product and will wait as long as that takes because I trust Elecraft. The $6000 up front is not an issue as what else would it be doing except drawing ridiculous interest rates in a bank? Of course, if someone put the amp on a credit card and has been financing the purchase at 18%, then I could understand the consternation?but let?s hope no one that put a pre-purchase on a $6000 amp has to finance it long-term on a credit card :) Regards, Tom NY4I > On Apr 3, 2018, at 10:58 PM, Torrey Mitchell wrote: > > My #52 arrived here in Iowa one week ago.

Many folks have had this issue with Macs, including me. One way is to use a USB?>Thunderbolt adapter; it appears that several years ago Apple changed something in the way USB2 is handled in the OS and the result is audio occasionally getting sent to the internet speakers instead of the USB Audio CODEC. That adapter thing is how I resolved it on my MacBook Pro. Another way, and the one I use on my iMac that does not have a Thunderbolt port, is to bring up the MIDI application and set the USB Audio CODEC input and output to 44100 Hz instead of the recommended 48000 Hz. That has cured it for me and many others. You could also try that on your MacBook instead of using an adapter - up to you.I like the adapter method, as it frees up my USB port for other ?stuff?. > > > > 73, Jim / W6JHB > > > >> On Apr 3, 2018, at 8:53 AM, Craig Taylor wrote: > >> > >> I am running a MacBook Pro with my K3.

The amp factors into our plans so I was trying to get a sense of projects coming up towards the Fall and Winter contest season. If we are already ploughing through the orders from the second week, that tells me something different for station planning than where we are now about how many minutes into the first day. Amp #52 was ordered 15 minutes after. Amp #56 was ordered 43 minutes after the ordering started. And yes, I know that is not necessarily linear as ordered came in from multiple channels. > > > > Lastly, I would rather wait for a great product and will wait as long as that takes because I trust Elecraft. The $6000 up front is not an issue as what else would it be doing except drawing ridiculous interest rates in a bank? Of course, if someone put the amp on a credit card and has been financing the purchase at 18%, then I could understand the consternation?but let?s hope no one that put a pre-purchase on a $6000 amp has to finance it long-term on a credit card :) > > > > Regards, > > > > Tom NY4I > > > > > > > > > > > >> On Apr 3, 2018, at 10:58 PM, Torrey Mitchell wrote: > >> > >> My #52 arrived here in Iowa one week ago.

I place a small book between the front panel and the floor of my shack. This prevents any pressure on the three green lights protruding a little from the panel. This configuration allows full ventilation access and facilitates routing the cables to the amplifier (they face upwards to the amp). Also allows easy access to the PS ON/OF switch.

I seriously doubt Microbit can help either, but if you contact them, be aware that RemoteRig comes from Sweden.? Michael speaks excellent English, however as is always true when communicating across international borders, technical things in one country may have different names in another. The odds are extremely high [like p=0.99] that when you reset your router, DHCP assigned a different IP address to your RRC's, or to your wireless adapter if you're using WiFi.? One never knows with Apple [being different and obscure seems to be part of their business model], but just like your RRC's, most routers have an internal web server you can access with any browser. The IP address for our ATT is 192.168.1.254? I found it just by starting at 192.168.1.255 and working down, most seem to be at the upper or lower end of the range of the last octet. 192.168.. is one of several IP ranges that are never broadcast [i.e. private to your internal network] and are most commonly used in consumer products. You can then look at the local device list and get the DHCP-assigned IP for your RRC(s).? Go in to them and change the IP settings and it will likely work. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 4/5/2018 7:58 AM, Don Wilhelm wrote: > Ron, > > You might find more knowledgeable people at the Remote Rig forums.? > The ham world is mainly Windows oriented, and that includes the > support staff at Elecraft, so questions about mac applications and > Apple gear may not have easy answers for them. > > 73, > Don W3FPR > > On 4/4/2018 9:05 AM, Ron Gould wrote: >> I have a pair of remote rigs which I use to remotely control a >> Elecraft K3S via Elecraft K3/0 mini which I purchased from Elecraft.? >> Everything has been working fine until I had to reset my router, a >> Apple Time Capsule.?

One of these methods is likely to work for you: - rotating the WIDTH/SHIFT controls - tapping XFIL to cycle through normalized crystal filter bandwidths - turning APF on/off (hold of XFIL switch) - pushing/holding the SHIFT control to normalize the passband for the present mode - pushing/holding the WIDTH control to alternate between two floating presets (I/II) or fixed presets (NORM1/NORM2); see page 26 of the owner?s manual - alternating VFOs (A/B switch); they can each have different filter settings - programming PF1 and/or PF2 to execute macros that set bandwidth to specific values - K-Pod (16 programmable functions plus a remote VFO/RIT knob) - Computer control (the K3/K3S has a rich set of remote control commands, including shift and width setup) Let me know if you have questions about any of the above 73, Wayne N6KR > On Apr 6, 2018, at 8:41 AM, Dave Scarfe wrote: > > I love my K3S.

The idea of my usage is to give me similar control of the K3 that I would get from leaning across the desk to the rig - just to make life simple. Such as: I have some keys set up as 3x4 keypad on the face of the K3, others as preset frequencies/mode/filter, can select mode, band up/dn, various audio settings, and up/down 50/10/1 kcs, and a few other toggle type macros. I also use a K-pod. Had the K-Pod been available when I originally set up the Genovation, I would have stopped with the K-Pod. Creatively building the macros for the K-Pod allows me to nearly control the K3 as well as from the Genovation and the K-Pod has a VFO to boot. The K-Pod is an excellently thought out product, limited only by the imagination of the user.

This has resulted in a measurement technique with arguable advantages, achieved with a homebrew, very specialized test setup, implemented for the 40m band. While the author apparently had access to some lab-quality test equipment for testing his home-brew test equipment, it appears to me that it would be much more expensive to implement his receiver testing setup using only a combination of off-the-shelf lab test equipment, if that is even practically doable. I haven't read everything on the website, but for those who find the German confusing, the following is my summary overview of some of the site content. He put up a huge horizontal V antenna that picks up high signal voltages from BC signals etc, so rx overload and even damage is a concern. His latest home-built rx is good, but he still looks for improvements, and he focuses on preselectors as a possible way to improve performance. Preselectors don't seem very popular these days, but the author makes a case that at least for his extreme conditions, they can contribute in a meaningful way to how strong, nearby interfering signals can be handled. This turns out to be the case for his homebrew rx and also several commercial rigs, including the K3. The K3 of course has its roofing filter as standard equipment. The IC-751 and an FT-1000 Field have both been modified to add roofing filters that are not part of the original design. The IC-7300 which places its ADC at the front end, cannot be so modified due to its basic architecture, and is tested as manufactured. To test for unwanted response to nearby strong signals the author used 3 types of test setups: IP3 (two input frequencies), continuous noise spectrum (measuring Noise Power Ratio) , and the broadband spectrum carefully generated by pulses, which varies with pulse frequency. The latter method is considered the best, and most similar to real band conditions, and applicable to all the tested receivers (the IP3 method makes no sense for the IC-7300 type architecture). The pulse generator setup has a notch filter that keeps the pulse spectrum out of the rx passband, which is set to 500 Hz. When the power of the pulses is cranked up, the rx does respond eventually, but the higher the pulse power tolerated, the better the rx. The table presented shows "tolerated" (in some sense) pulse power in dBm for the different receivers with and without use of the homebrew preselector, which always helps. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Bob DeHaney Sent: Friday, April 06, 2018 12:52 PM To: elecraft at mailman.qth.net Subject: [Elecraft] OE3HKL's Measurements You are correct Breitband means Wide Band in English.

Most of the time > preamp 1 is also off. I've had the opposite experience. MDS of the original K3 was woefully poor above 15M, even with the preamp switched in. As luck would have it, I have a very nice ARR GAsFET 6M preamp on the shelf that I'd used in Chicago that I inserted at the RX antenna patch point; I found that it improved the MDS all the way down to 12M. I would have missed a LOT of QSOs without that preamp. Of course, like everyone else, sometimes my noise level is lower than at other times, and a solar system 500 ft from my main antenna raises it by 10 dB on 10 and 6 when the sun is hitting it. When the K3S was introduced, I quickly replaced the Synth boards and the Transverter board to get that improved preamp, simplifying my RX antenna switching. I do find, though, that the GAsFET preamp has a slightly lower NF, so I continue to use it during the 6M season. 73, Jim K9YC From ebasilier at cox.net Fri Apr 6 23:27:58 2018 From: ebasilier at cox.net (Erik Basilier) Date: Fri, 6 Apr 2018 20:27:58 -0700 Subject: [Elecraft] OE3HKL's Measurements In-Reply-To: References: Message-ID: <01cf01d3ce20$6d762150$486263f0$@cox.net> Since I do read German, here is my quick attempt to translate the section ("Fazit") where the author summarizes his findings about testing methods and receiver performance: "No IP3 value can be derived from the results of this measurement technique using broadband pulses with a crystal-based notch filter. However, the results do show the resistance to interference generated from summation of a broadband interfering spectrum, which seems crucial to me when it comes to evaluating the interference handling of an SDR with the ADC at the front. In any case, the listed signal levels (for +10 dB (S+N)/N) provides a very good way to compare the relative performance of the tested receivers; the higher the listed signal level (dBm), the better the better the performance in handling strong signals. Roofing filter quality can be observed by proper selection of pulse frequency for close-in measurement (use e.g. 2 kHz). This is in contrast to what can be done with two-signal testing (even using many different frequencies). In particular, the pulsing measurement technique illustrates how the use of a preselector influences receive performance. Earlier one could only rely on subjective impresisons in practical use. Our results show that use of a preselector always makes sense, even when used with the very best receivers!!! Even with the RX-OE3HKL receiver design which by itself can handle levels that are up to 26 dB higher, improvements up to 9 dB from the preselector are seen. Notable is the performance of the IC-751A with preselector and roofing filter: Results are almost as good as those of my own receiver design. However, in contrast to the situation when using the 2-signal method of testing, when using the pulse signal, without the preselector, the roofing filter doesn't yield much improvement. Apparently the reason is that the broadband signal quickly overloads the front end circuits. Without using the broadband pulse signal it would not be possible to reconcile lab measurements with real-world reception results seen when using the 2x120m V-antenna! However, the improvement from using the preamp shows up only if the preselector handles large signals at least as well as the rx itself. The K3 is by far the best of the commercial units, and without having to be modified. This result is confirmed by practical experience in reception testing using the 120m-V-beam during a contest. Results improved by another 2-4 dB after a firmware update was performed (see the red corrections). The IC-7300 clearly performs more poorly than the analog radios with roofing filters, in practical reception as well as in lab measurement. When the preselector is added, it partly outperforms the FT-1000 Field with preselector and roofing filter. Based on this result, I conclude that an SDR with the ADC in the front end, when used with good antennas and in the presence of sftong signals, should if possible only be used in combination with a preselector. I would like to establish that the here described test setup with its broadband discrete signal is a better proxy for real-world interference signals than is the stochastic noise signal used in Noise Power Ratio testing. Furthermore, by varying the pulse frequency, one can vary the intensity of the interference in a way that is clearly quantified by observing spectrum analyzer output. In contrast, the noise level in NPR measurement is defined by the high ratio of peak value to rms (10 to 11). In this scenario t would likely take very expensive equipment to perform measurements with sufficient accuracy for comparison purposes. I would also like to mention that NPR measurements at 3dB (S+N)/N will not be sufficient to take into account the effect of higher-order IM products. To achieve that, one must increase input levels to the point that a further increase of 1 dB will lead to a 3 dB increase at the output (3rd order). This is what it takes to get results from the NPR method to agree with results from the pulse signal method." My apologies in advance to OE3HKL for any misinterpretation I might have made. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Erik Basilier Sent: Friday, April 06, 2018 5:06 PM To: 'Bob DeHaney' ; elecraft at mailman.qth.net Subject: Re: [Elecraft] OE3HKL's Measurements The German website describes how this om has developed his capabilities over the years, based on his specific circumstances and needs. This has resulted in a measurement technique with arguable advantages, achieved with a homebrew, very specialized test setup, implemented for the 40m band. While the author apparently had access to some lab-quality test equipment for testing his home-brew test equipment, it appears to me that it would be much more expensive to implement his receiver testing setup using only a combination of off-the-shelf lab test equipment, if that is even practically doable. I haven't read everything on the website, but for those who find the German confusing, the following is my summary overview of some of the site content. He put up a huge horizontal V antenna that picks up high signal voltages from BC signals etc, so rx overload and even damage is a concern. His latest home-built rx is good, but he still looks for improvements, and he focuses on preselectors as a possible way to improve performance. Preselectors don't seem very popular these days, but the author makes a case that at least for his extreme conditions, they can contribute in a meaningful way to how strong, nearby interfering signals can be handled. This turns out to be the case for his homebrew rx and also several commercial rigs, including the K3. The K3 of course has its roofing filter as standard equipment. The IC-751 and an FT-1000 Field have both been modified to add roofing filters that are not part of the original design. The IC-7300 which places its ADC at the front end, cannot be so modified due to its basic architecture, and is tested as manufactured. To test for unwanted response to nearby strong signals the author used 3 types of test setups: IP3 (two input frequencies), continuous noise spectrum (measuring Noise Power Ratio) , and the broadband spectrum carefully generated by pulses, which varies with pulse frequency. The latter method is considered the best, and most similar to real band conditions, and applicable to all the tested receivers (the IP3 method makes no sense for the IC-7300 type architecture). The pulse generator setup has a notch filter that keeps the pulse spectrum out of the rx passband, which is set to 500 Hz. When the power of the pulses is cranked up, the rx does respond eventually, but the higher the pulse power tolerated, the better the rx. The table presented shows "tolerated" (in some sense) pulse power in dBm for the different receivers with and without use of the homebrew preselector, which always helps. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Bob DeHaney Sent: Friday, April 06, 2018 12:52 PM To: elecraft at mailman.qth.net Subject: [Elecraft] OE3HKL's Measurements You are correct Breitband means Wide Band in English.

Same goes for the CW filters, they will work but may not be centered at your desired sidetone pitch. The audio Spectrum analyzer is easy to obtain.? Go to my website www.w3fpr.com and scroll down on the opening page.? You will see links to both version 5.17 and version 16 of Spectrogram (both freeware). SpectrumLab also has a nice audio spectrum analyzer (free). You may be able to get by with using broadband antenna noise from a "dead band" instead of a broadband noise generator, although the noise generator will be more convenient.? Just make certain there are no signals on the band you use. You can find Spectrogram plots of what you should be looking for at http://www.mmccs.com/mmarc/n0ss/index_k2.html.?

If anyone has difficulty getting to the numbers, let me know and I can repeat them here, but for now I will just refer you to the website again. Here is a short url for that page: https://tinyurl.com/ycn9kbss Scroll down to the first handwritten table. The left-hand column lists the different radios tested. 3 columns to the right shows test results for different pulse frequencies. Presumably, a higher pulse frequency means the interference spectrum is more spread out around the wanted signal. However, this is not quantified or described in detail. Remember, results of this test method are strongly dependent on the design of the pulse generator etc, so the if someone would like to duplicate or compare to his numbers, they would have to duplicate his exact equipment, or come up with a new similar test setup that could be regarded as a standard. For each radio, there are two rows of results (for each pulse frequency). The first row represents the radio without preselector (but modified to add a roofing filter, except in the case of the IC-7300). The second row represents the same radio with the addition of the preselector, which is his personal design, also described at the website. If I am not mistaken, the preselector is entirely passive. All the result numbers are negative dBm values. This means that a smaller negative number represents a stronger interference signal that is in some sense tolerated. E.g. -20dBm is a great result, but -50dBm is a poor result. None of the numeric results can be translated into, or compared with, numbers published by Sherwood or the ARRL. However, he makes a pretty good case that his measurement method might be "better" than those conventional measurements in representing the performance characteristics that are relevant in practical ham use under heavy interference from close-in strong signals. For the ARRL or Sherwood to adopt his approach they would likely have to invest in additional test equipment including custom-built items, and justify a standard method of doing this kind of testing, so I am not holding my breath. The inclusion of the IC-7300 shows that the website content is not very old, but other than the K3 he has not included any of the several radios on the market today that incorporate roofing filters as a standard part of the design. Perhaps we could hope that some kind hams in Europe would lend him additional radios for testing with his unique test equipment. As to his own conclusions, they should be covered by the text I already translated. Are any of his statements (as translated) unclear? Remember, no real world radio has a "true" performance level even in principle. Every time we look at performance numbers, they reflect imperfect concepts developed in our small human minds, whether they are considered "standard" or not. A concept such as "better" is usually not an objective way of describing things. 73, Erik K7TV -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Igor Sokolov Sent: Saturday, April 07, 2018 6:49 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] OE3HKL's Measurements Eric, Can you possible give a summary of the results of his measurements and conclusions he has made? 73, Igor UA9CDC From k6dgw at foothill.net Sat Apr 7 14:36:02 2018 From: k6dgw at foothill.net (Fred Jensen) Date: Sat, 7 Apr 2018 11:36:02 -0700 Subject: [Elecraft] Fred's vs Elecraft manuals In-Reply-To: References: Message-ID: <753fc5d4-c253-ee5d-fb49-117c86251f7d@foothill.net> Fair question.? From my perspective... Elecraft manuals are well written and follow the pattern of all manufacturer's User Manuals.? They are like the "dash one" in the set of Air Force Tech Orders for some piece of equipment ... "How to fly the airplane."? They describe how to configure cables and other hardware, how to use the menu system, and how to operate the radio. Fred's book approaches it sort of at right angles to Elecraft, delving much more deeply into why you would want to choose one configuration over another, the practical effects of various configuration options, etc.? It gives alternate tables and organization for some of the data that gets buried in larger tables in the Elecraft manual.? The Elecraft manual will tell you some setting is remembered by band ... Cady will follow that through with what it means in operational situations. They are very much complementary, and I find I use them about equally.?

Let?s start by saying the KE7X books do not have any information needed to operate the radios that is not in the Elecraft Owner?s manuals. Owner?s manuals are by design succinct and concise descriptions of the controls and features of the radio. Elecraft manuals are very well done but I found during my 40+ years as an EE prof that there are various ways that people learn. Some are visual learners and learn by seeing diagrams and images, some can gain comprehension just be reading. Others are more hands-on learners, needing the ?lab experience? to cement their understanding of the concepts. I?m a visual and hands-on learner. When I first got my K3 I had trouble understanding how the sub receiver worked and what the different antenna switching options were. So I drew it out in a diagram and that made it much more clear to me. If that helped me, wouldn?t it help others? So the idea of a K3 book was born. (The original title was to be ?The Hitchhiker?s Guide to the K3? but I got talked out of that!) The concept that takes these books beyond the Elecraft manuals is support for the visual, reading, and doing learning styles. There are many, many diagrams. In the K3S book there are 131 diagrams, 16 on the sub receiver alone. There are expanded explanations (and diagrams) for all radio operations and in-depth explanations of topics such as the various controls for the receiver?s AGC. And to top it all off, most topics have a ?lab exercise? that you can do sitting at your radio to make sure you understand the concept. The printed versions of the books all have an index and, of course, the pdf versions can be easily searched for what you are looking for. www.ke7x.com has more information on all 12 current KE7X Elecraft books with tables of contents and ordering information. 73, Fred ________________________________ From: elecraft-bounces at mailman.qth.net on behalf of Mike Markowski Sent: Saturday, April 7, 2018 12:04 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Fred's vs Elecraft manuals Fred and all, Can you describe in general how your books differ from Elecraft manuals?

A receiver should have enough gain to put its internal noise floor below the external, atmospheric noise floor, so that it doesn't become the limiting factor in hearing weak signals close to the noise. That's what makes a preamp necessary. Certainly, if your noise floor is lower than here in urban North America, there may be cases where a preamp does us no good, but is necessary for you. I think I once posted a case study here a while ago... but I would have to go searching for it. The numbers I used were definitely US-biased. Life for a ham here has become a really discouraging exercise in trying to copy signals below your neighbors' app-enabled pet massagers and internet-controlled wine coolers, all fed by those infernal switch-mode power supplies. My two neighbors' homes are really just enormous square wave-producing things. This is also why everybody you hear is running 1,000 watts or more. It's power inflation. The military spends millions on radar jamming equipment... when all they'd have to do is do whatever my neighbor Johnny is doing. He must have a phased array radar, arc-welding, barrage jamming plant next door. If you ever bring your rig over here on vacation, be sure to pack a 60 dB attenuator with it. R, Al?

The wind has been howling all day but the antennas are still up and the power is still on.? So I spent the day watching the Masters and practicing CW with my left hand.? After the first week or so it felt less strange.? The biggest problem I have is to remember how to send each character.? Over the years I have forgotten my lookup table.? It is much like typing.? I think about what I want to write and my fingers do the work.? I have to look at the keyboard to see where keys are but my fingers know where to go without me thinking.? Sending code with my right hand is like that.? I really need to think about each character when I send with my left hand. ?? The paddles are wired oppositely from my working set of paddles so the thumb and forefinger are doing the same thing with either hand.? It is just there is no lookup table in my head telling me how to send.? So I have been working my way through the alphabet and sending random character groups; today I sent names from the leaderboard.? The first week was quite frustrating but I'm getting better, gaining strength and dexterity.? Sending too slowly confused me to no end so I set my WinKeyer to about 18 wpm or so.? Once I raised the speed sending became easier.? Now it is simply trying to remember how each character is formed.? In a few months of practice I should be able to get on the air with my non-dominant hand.? I am sure everyone will notice.

It is all clear now. According to his measurements his RX is the best with and without preselector. K3 comes the second best. Preselector adds 12-13db of improved performance to K3.? The strongest impact by preselector is for IC7300 - the radio that have no roofing filter because of it's architecture. 73, Igor UA9CDC 07.04.2018 23:33, Erik Basilier ?????: > Igor, are you saying that you could not view the numbers at his website? If anyone has difficulty getting to the numbers, let me know and I can repeat them here, but for now I will just refer you to the website again. > Here is a short url for that page: > https://tinyurl.com/ycn9kbss > Scroll down to the first handwritten table. The left-hand column lists the different radios tested. 3 columns to the right shows test results for different pulse frequencies. Presumably, a higher pulse frequency means the interference spectrum is more spread out around the wanted signal. However, this is not quantified or described in detail. Remember, results of this test method are strongly dependent on the design of the pulse generator etc, so the if someone would like to duplicate or compare to his numbers, they would have to duplicate his exact equipment, or come up with a new similar test setup that could be regarded as a standard. For each radio, there are two rows of results (for each pulse frequency). The first row represents the radio without preselector (but modified to add a roofing filter, except in the case of the IC-7300). The second row represents the same radio with the addition of the preselector, which is his personal design, also described at the website. If I am not mistaken, the preselector is entirely passive. All the result numbers are negative dBm values. This means that a smaller negative number represents a stronger interference signal that is in some sense tolerated. E.g. -20dBm is a great result, but -50dBm is a poor result. None of the numeric results can be translated into, or compared with, numbers published by Sherwood or the ARRL. However, he makes a pretty good case that his measurement method might be "better" than those conventional measurements in representing the performance characteristics that are relevant in practical ham use under heavy interference from close-in strong signals. For the ARRL or Sherwood to adopt his approach they would likely have to invest in additional test equipment including custom-built items, and justify a standard method of doing this kind of testing, so I am not holding my breath. The inclusion of the IC-7300 shows that the website content is not very old, but other than the K3 he has not included any of the several radios on the market today that incorporate roofing filters as a standard part of the design. Perhaps we could hope that some kind hams in Europe would lend him additional radios for testing with his unique test equipment. As to his own conclusions, they should be covered by the text I already translated. Are any of his statements (as translated) unclear? Remember, no real world radio has a "true" performance level even in principle. Every time we look at performance numbers, they reflect imperfect concepts developed in our small human minds, whether they are considered "standard" or not. A concept such as "better" is usually not an objective way of describing things. > > 73, > Erik K7TV > > -----Original Message----- > From: elecraft-bounces at mailman.qth.net On Behalf Of Igor Sokolov > Sent: Saturday, April 07, 2018 6:49 AM > To: elecraft at mailman.qth.net > Subject: Re: [Elecraft] OE3HKL's Measurements > > Eric, > > Can you possible give a summary of the results of his measurements and conclusions he has made? > > 73, Igor UA9CDC > > > > > From fcady at montana.edu Sun Apr 8 09:21:24 2018 From: fcady at montana.edu (Cady, Fred) Date: Sun, 8 Apr 2018 13:21:24 +0000 Subject: [Elecraft] Fred's HHG vs Elecraft manuals de KE7X In-Reply-To: <6EAF21E3-BD27-4462-A863-EEA59785D7BB@me.com> References: <6EAF21E3-BD27-4462-A863-EEA59785D7BB@me.com> Message-ID: Yea, another Douglas Adams fan. ________________________________ From: Joan Sent: Sunday, April 8, 2018 12:26 AM To: Cady, Fred Cc: Mike Markowski; elecraft at mailman.qth.net Subject: Re: [Elecraft] Fred's HHG vs Elecraft manuals de KE7X Fred, I?ve just appended my copy of your book to read: The Hitchhikers?

Owner?s manuals are by design succinct and concise descriptions of the controls and features of the radio. Elecraft manuals are very well done but I found during my 40+ years as an EE prof that there are various ways that people learn. Some are visual learners and learn by seeing diagrams and images, some can gain comprehension just be reading. Others are more hands-on learners, needing the ?lab experience? to cement their understanding of the concepts. I?m a visual and hands-on learner. When I first got my K3 I had trouble understanding how the sub receiver worked and what the different antenna switching options were. So I drew it out in a diagram and that made it much more clear to me. If that helped me, wouldn?t it help others? So the idea of a K3 book was born. (The original title was to be ?The Hitchhiker?s Guide to the K3? but I got talked out of that!) >> The concept that takes these books beyond the Elecraft manuals is support for the visual, reading, and doing learning styles. There are many, many diagrams. In the K3S book there are 131 diagrams, 16 on the sub receiver alone. There are expanded explanations (and diagrams) for all radio operations and in-depth explanations of topics such as the various controls for the receiver?s AGC. And to top it all off, most topics have a ?lab exercise? that you can do sitting at your radio to make sure you understand the concept. >> The printed versions of the books all have an index and, of course, the pdf versions can be easily searched for what you are looking for. >> https://nam03.safelinks.protection.outlook.com/?url=www.ke7x.com&data=02%7C01%7C%7C9f89f0d9820449cbbfc208d59d19deae%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636587656789761289&sdata=Vm0EbZlIY7l%2BlaYsff7q5hyZ%2BQ1UTYUiOAiME5fDIqk%3D&reserved=0 has more information on all 12 current KE7X Elecraft books with tables of contents and ordering information. >> >> >> 73, >> >> Fred >> >> ________________________________ >> From: elecraft-bounces at mailman.qth.net on behalf of Mike Markowski >> Sent: Saturday, April 7, 2018 12:04 PM >> To: elecraft at mailman.qth.net >> Subject: Re: [Elecraft] Fred's vs Elecraft manuals >> >> Fred and all, >> >> Can you describe in general how your books differ from Elecraft manuals? >> I haven't found Elecaft manuals to be lacking and very much like how >> direct and concise they are.

Maybe others know better? The book is an intro, though very detailed!, and doesn't cover much in the way of RF to my recollection. It would be a foundation that makes RF design easy to follow, though. Others might have better recommendations for ham-specific books. But if you leaf through something like ARRL's "Introduction to Radio Frequency Design," you'll probably get more from it after a book like Art of Elec. 73, Mike ab3ap On 04/08/2018 11:28 AM, Robie Elms wrote: > Which edition is the most useful for hams? > > Robie AJ4F > >> On Apr 8, 2018, at 10:14, Mike Markowski >> wrote: >> >> Chuck and all, >> >> It really is a great book, the best I've found on the topic for my >> style of learning.

When this question came up in another forum, one member advised: "The second edition has circuit ideas and examples, where the third edition replaced it with chapter review exercises (more like an academic textbook). I have no interest in the homework assignments, and feel a lot of value was lost from this. Yes, there are minor updates like micro-controllers, but there are better resources for that. If I had to pick only one, I'd keep my 2nd Ed." Based on that, I recently bought a (used) copy of the second edition.

To judge the usefulness of this book, it is good to learn why it exists. As you read in the preface to the first edition, the book grew out of notes from a course at Harvard University on "laboratory electronics". This type of course is similar to other courses at other universities and the important thing to note is that the target student is NOT an E.E. major. In fact, the preface states that the book is designed to be used by students that do not have previous electronics knowledge or experience. But, these were Harvard students so I grant those students' capabilities as better than average. My undergraduate degree is Physics and back in the 1960s, my physics curriculum included a similar course study. This was all about using lab equipment but also making the necessary little electronic gadgets that were important to work in a physics research laboratory. When I took my course, the book "The Art of Electronics" did not exist and we never had a text book in our course. I wanted more though so I also signed up for the EE department's equivalent course which started with FET transistors which was the new thing at the time and quickly went into digital electronics and digital logic circuits. I never learned about building audio or RF circuits in my physics oriented electronics course nor in the EE course. Importance was given to digital and computer circuits (~1967). The book "The Art ..." is similar, its main focus is primarily in using electronics to interface with equipment, digital/analog, digital/digital, and so on with just a sprinkle, in comparison, for RF. 73, phil, K7PEH > On Apr 8, 2018, at 8:45 AM, Frank O'Donnell wrote: > > Hi all, new ham/KX3 owner/list member here. > > When this question came up in another forum, one member advised: "The second edition has circuit ideas and examples, where the third edition replaced it with chapter review exercises (more like an academic textbook).

Owner?s manuals are by design succinct and concise descriptions of the controls and features of the radio. Elecraft manuals are very well done but I found during my 40+ years as an EE prof that there are various ways that people learn. Some are visual learners and learn by seeing diagrams and images, some can gain comprehension just be reading. Others are more hands-on learners, needing the ?lab experience? to cement their understanding of the concepts. I?m a visual and hands-on learner. When I first got my K3 I had trouble understanding how the sub receiver worked and what the different antenna switching options were. So I drew it out in a diagram and that made it much more clear to me. If that helped me, wouldn?t it help others? So the idea of a K3 book was born. (The original title was to be ?The Hitchhiker?s Guide to the K3? but I got talked out of that!) >>> The concept that takes these books beyond the Elecraft manuals is support for the visual, reading, and doing learning styles. There are many, many diagrams. In the K3S book there are 131 diagrams, 16 on the sub receiver alone. There are expanded explanations (and diagrams) for all radio operations and in-depth explanations of topics such as the various controls for the receiver?s AGC. And to top it all off, most topics have a ?lab exercise? that you can do sitting at your radio to make sure you understand the concept. >>> The printed versions of the books all have an index and, of course, the pdf versions can be easily searched for what you are looking for. >>> https://nam03.safelinks.protection.outlook.com/?url=www.ke7x.com&data=02%7C01%7C%7C9f89f0d9820449cbbfc208d59d19deae%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636587656789761289&sdata=Vm0EbZlIY7l%2BlaYsff7q5hyZ%2BQ1UTYUiOAiME5fDIqk%3D&reserved=0 has more information on all 12 current KE7X Elecraft books with tables of contents and ordering information. >>> >>> >>> 73, >>> >>> Fred >>> >>> ________________________________ >>> From: elecraft-bounces at mailman.qth.net on behalf of Mike Markowski >>> Sent: Saturday, April 7, 2018 12:04 PM >>> To: elecraft at mailman.qth.net >>> Subject: Re: [Elecraft] Fred's vs Elecraft manuals >>> >>> Fred and all, >>> >>> Can you describe in general how your books differ from Elecraft manuals? >>> I haven't found Elecaft manuals to be lacking and very much like how >>> direct and concise they are.

I know many regard math as difficult, but a book I used when teaching at Valparaiso Tech Institute was "Basic Math for Electronics by Nelson M. Cooke. It taught math by using many electronics formulas and therefore was invaluable to help students learn electronics and basic math. I believe the latest is the 7th edition. But I used the first edition. I will have to look for a free download.

A better way of thinking about it is that as frequency goes up, stray (parasitic) elements of components become increasingly significant (that is, L and C in a resistor, R and L in a capacitor, R and C in an inductor), wiring (including traces on a single layer circuit board) first become inductors, then antennas, and their capacitance to other circuit elements and their inductive coupling to other wiring becomes significant, and traces above a "ground layer" on a circuit board become transmission lines. And the TIME it takes for signals to move along wires and lines becomes significant. The dielectric properties of circuit board become significant. The spacing between circuit traces becomes significant. In other words, all of the things that can often be ignored at lower frequencies must be considered at higher frequencies. That's not "art," it's not "black magic," its pure science. 73, Jim K9YC From tim.n9puz at gmail.com Sun Apr 8 15:35:20 2018 From: tim.n9puz at gmail.com (Tim McDonough N9PUZ) Date: Sun, 8 Apr 2018 14:35:20 -0500 Subject: [Elecraft] KX2 go-box In-Reply-To: References: Message-ID: He does beautiful work.

Owner?s manuals are by design succinct and concise descriptions of the controls and features of the radio. Elecraft manuals are very well done but I found during my 40+ years as an EE prof that there are various ways that people learn. Some are visual learners and learn by seeing diagrams and images, some can gain comprehension just be reading. Others are more hands-on learners, needing the ?lab experience? to cement their understanding of the concepts. I?m a visual and hands-on learner. When I first got my K3 I had trouble understanding how the sub receiver worked and what the different antenna switching options were. So I drew it out in a diagram and that made it much more clear to me. If that helped me, wouldn?t it help others? So the idea of a K3 book was born. (The original title was to be ?The Hitchhiker?s Guide to the K3? but I got talked out of that!) >>>> The concept that takes these books beyond the Elecraft manuals is support for the visual, reading, and doing learning styles. There are many, many diagrams. In the K3S book there are 131 diagrams, 16 on the sub receiver alone. There are expanded explanations (and diagrams) for all radio operations and in-depth explanations of topics such as the various controls for the receiver?s AGC. And to top it all off, most topics have a ?lab exercise? that you can do sitting at your radio to make sure you understand the concept. >>>> The printed versions of the books all have an index and, of course, the pdf versions can be easily searched for what you are looking for. >>>> https://nam03.safelinks.protection.outlook.com/?url=www.ke7x.com&data=02%7C01%7C%7C9f89f0d9820449cbbfc208d59d19deae%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636587656789761289&sdata=Vm0EbZlIY7l%2BlaYsff7q5hyZ%2BQ1UTYUiOAiME5fDIqk%3D&reserved=0 has more information on all 12 current KE7X Elecraft books with tables of contents and ordering information. >>>> >>>> >>>> 73, >>>> >>>> Fred >>>> >>>> ________________________________ >>>> From: elecraft-bounces at mailman.qth.net on behalf of Mike Markowski >>>> Sent: Saturday, April 7, 2018 12:04 PM >>>> To: elecraft at mailman.qth.net >>>> Subject: Re: [Elecraft] Fred's vs Elecraft manuals >>>> >>>> Fred and all, >>>> >>>> Can you describe in general how your books differ from Elecraft manuals? >>>> I haven't found Elecaft manuals to be lacking and very much like how >>>> direct and concise they are.

I bought my K3, SN4043, in 2010. It has an internal preamp (push PRE) which gives about 10-dB gain (I think). A few years went by and Elecraft announced the PR6 external "add-on" preamp to improve 10m and 6m receiver performance. They kind of admitted the bare K3 was lacking gain at those frequencies. That "system" gain minimum is needed to overcome following stage NF for best sensitivity (MDS). I've measured -145dBm MDS on 6m with my PR6. K3 was about -133 dBm without the PR6 on 6m (-73 dBm is S9; 9 s-units should be 6x9 = 54 dB; -73dBm-54dB = -129 dBm). Of course ambient noise will rule how weak a signal can be copied. On lower freq. HF bands thermal sky noise has long been that limitation; at 25-MHz Tsky starts to drop as one transitions into VHF. Recent (?) rise in residential/industrial RF noise has affected pretty much everyone (I live in a widely dispersed community of 4,000 in Alaska and noise at 2m has become terrible (S7 over a S3 noise floor). Use of a preamp may become unproductive at some level of noise (maybe). I do 6m eme and use a GasFet preamp at the antenna for minimizing NF and it helps enough over just using the PR6 (with internal preamp off). I use DIGOUT1 to turn on/off the PR6. Since it has a nice bypass, I use that to connect to my tower-top 6m preamp. BTW I have copied 6m-eme signals just using the PR6. I don't have a K3s so assuming preamp-2 is equivalent to the PR6-10 (expanded to 24-MHz). I actually wonder if there are some arc-welder rock bands? Or dueling Plasma TV's? I'm heading up north (frequency-wise) to 1296 for a little quiet-time 73, Ed - KL7UW Hi, Barry, It's not the signals that determine whether you need a preamp, it's the noise level. A receiver should have enough gain to put its internal noise floor below the external, atmospheric noise floor, so that it doesn't become the limiting factor in hearing weak signals close to the noise. That's what makes a preamp necessary. Certainly, if your noise floor is lower than here in urban North America, there may be cases where a preamp does us no good, but is necessary for you. I think I once posted a case study here a while ago... but I would have to go searching for it. The numbers I used were definitely US-biased. Life for a ham here has become a really discouraging exercise in trying to copy signals below your neighbors' app-enabled pet massagers and internet-controlled wine coolers, all fed by those infernal switch-mode power supplies. My two neighbors' homes are really just enormous square wave-producing things. This is also why everybody you hear is running 1,000 watts or more. It's power inflation. The military spends millions on radar jamming equipment... when all they'd have to do is do whatever my neighbor Johnny is doing. He must have a phased array radar, arc-welding, barrage jamming plant next door. If you ever bring your rig over here on vacation, be sure to pack a 60 dB attenuator with it.

You *DO NOT WANT* the station bonding ("ground") and the V- rail to be interconnected. If you allow that to happen, particularly at the transceiver and power supply, the station ground becomes an alternate return for the high current pulses during transmit. When the station bonding is allowed to "float" with the high current pulses any other accessory connected to the bonding (particularly "linear" bonding) sees a varying ground reference level which contributes to "RF feedback" as that varying reference "pumps" (excites) any pin 1 problem in the device. Keep all of the transmitter power supply return current confined to the power cable between the rig and the power supply. Make sure all power supply connections are tight and all power cords as short as possible. Always use the largest practical wire for all power cords. If possible, use twisted pair cables, *bolted* connections (like on the Astron RS/VS series power supplies) and multiple, parallel pin connections in any power connectors. 73, ...

I hope I understood you correctly, as I now don't feel so bad about using old fashioned screw terminal blocks for all DC power. I feel they provide solid, unmoving, and permanent connections. I do not like the push on Power Poles, as I flat do not trust them - too many failures. Many such from merely moving a piece of equipment and slightly disturbing the wires. And, yes - I do know how to put Power Pole connectors together properly. Hence, with the exception of the required plugin on the K3 - I do not use them any longer. That plugin has a fixed strain relief installed on it - in case I move the rig a tenth of an inch. Bonus: No expensive plugs or tools required!

I just added a used KAT500 to my lineup (waiting for the KPA1500 backlog to clear before I order) and it's working great.? The person that I purchase it from did not include the RS232 cable that has the small data jack on the one end to program the KAT500. I use one line to the coax switch at the tower so I need the KAT500 to remain on the same antenna port.? The previous owner used all of the antenna connections so as I change bands on the K3, the KAT500 follows, as it should, and selects the antenna port previously programmed. I believe I am suppose to be able to program this manually but I'm not able to get the antenna port to remain as I change bands. My quesitons....Can I program the KAT500 through the PC connection to the KPA500 (I haven't tried that yet)?? Do I need to order the cable from Elecraft?? Can I do this manually and I just didn't follow the instructions correctly? Thanks everyone.

These are available from Elecraft, on the product list (www.elecraft.com/elecraft_prod_list.htm) The KAT500 has a very limited number of LEDs and buttons for user interface, so most of the heavy lifting (configuration) requires the KAT500 Utility, and a serial connection to the KAT500. Your KAT500 connects to your PC for the KAT500 Utility. It doesn?t go through the KPA500 for programming. The KPA500's serial connectors are for the Host PC and a transceiver (primarily Kenwood), not a KAT500. 73 de Dick, K6KR -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Larry Boekeloo Sent: Tuesday, April 10, 2018 18:26 To: elecraft at mailman.qth.net Subject: [Elecraft] KAT500,KPA500 Good evening everyone..... I just added a used KAT500 to my lineup (waiting for the KPA1500 backlog to clear before I order) and it's working great. The person that I purchase it from did not include the RS232 cable that has the small data jack on the one end to program the KAT500. I use one line to the coax switch at the tower so I need the KAT500 to remain on the same antenna port. The previous owner used all of the antenna connections so as I change bands on the K3, the KAT500 follows, as it should, and selects the antenna port previously programmed. I believe I am suppose to be able to program this manually but I'm not able to get the antenna port to remain as I change bands. My quesitons....Can I program the KAT500 through the PC connection to the KPA500 (I haven't tried that yet)? Do I need to order the cable from Elecraft? Can I do this manually and I just didn't follow the instructions correctly? Thanks everyone.

Message-ID: <005a01d3d13f$7afd45c0$70f7d140$@ieee.org> Hi All. I've been monitoring this list for a while, and have gained some useful insights from the posts. And now I have a question... I built my K3S #11310 last July, and I added the 100 watt amp and sub-receiver last December. A few weeks ago, I started hearing some unusual tones around 14380 KHz and 7259 KHz. The tones are much louder on 14380 than on 7259. At 14380, I hear a lower-pitched tone on 14279.80, and a higher pitched tone 14279.85. I hear both of these with no antenna connected. On 40m, the tone is quiet enough that the background noise overcomes the tone. But on 20m, the tones are quite loud. I also hear the tones on the sub-receiver. Prior to a few weeks ago, I'm certain these tones were not present. I saw the thread from 2012 about moving cables around in a K3, but if there was a build problem, wouldn't these sounds have appeared immediately? My routers are far away from my shack, and there is no new equipment in the shack. Any thoughts? Thanks.

Reloading the firmware and doing multiple power cycles did not fix it. Instead, if you can get to the P3 menu, go to the RESET option and press the knob. Or, if the P3 Utility still talks to the P3, go to the command tester and type: #RST; You may then find that the REF LEVEL is set way too high at 0 dB. Adjust REF LEVEL back down to about -120 dB and it should be back to normal. 73, Bob, N6TV On Tue, Apr 10, 2018 at 7:14 PM, Fred Jensen wrote: > My P3 waterfall disappeared when I turned the rig on tonight.

Ohms Law! If the transceiver power supply cable is short and heavy guage with multiple contact pins (or #10 - 1/4" bolted terminals) and #10 or 14" bolted terminals on the power supply, the impedance of the desired path in the power supply cable will be much, much less than the path through control cables (#16-#22 wires with single small pins) and any accessories. Elecraft/Astron come close with their power supply connection. I would appreciate it if the transceiver had bolted connections or at least double up the power poles and move from #12 to #10 cable. Doubling up on the power poles would allow using two (#12) cables further reducing the impedance (and voltage drop) of the desired path. 73, ...

The boost regulator is set for 13.7V which drops to 13.3V during 100W CW key down. The device is connected to the radio with about 30cm (1 ft) of #10 zip cord and PowerPoles. I have had problems in the past with the screws working loose on bolt attachments with some cheap Chinese equipment, so there is no substitute for checking the voltage drop under load, regardless of connector technology. Fortunately the internal volt meter in the K3(S) makes a good/look for the problem test easy. Car stereo installers may be a good source for flexible heavy gage wire. Also, PowerPole has some "75A" connectors which are a lot more robust (and not plug compatible) than the 15/30/45A ones generally seen. 73 Bill AE6JV * Notes on the TGE Boost Regulator: I have not noticed any RFI coming from it, but my antennas are away from the house on our 250 foot deep lot, so household RFI isn't as much of a factor as it would be on a smaller lot. I got the 30A circuit breaker option, and have popped it on occasion when running a FT8 frequency with low batteries. I now monitor the device's temperature with my hand and go QRT for a while when it gets too hot. Perhaps getting a device rated for more that 20A might be a good idea. During manufacture, they scraped all the numbers off the ICs in the device. My opinion of this kind of behavior can not be properly expressed in a polite forum. ----------------------------------------------------------------------- Bill Frantz | Truth and love must prevail | Periwinkle (408)356-8506 | over lies and hate. | 16345 Englewood Ave www.pwpconsult.com | - Vaclav Havel | Los Gatos, CA 95032 From k2asp at kanafi.org Wed Apr 11 13:45:12 2018 From: k2asp at kanafi.org (Phil Kane) Date: Wed, 11 Apr 2018 10:45:12 -0700 Subject: [Elecraft] Astron VS-35M Powwer Supply V- In-Reply-To: <0af82e92-137a-6b8b-e331-ef91cd47ab45@embarqmail.com> References: <345a7e1b382394b8c46d1b79295103cf.squirrel@www11.qth.com> <0af82e92-137a-6b8b-e331-ef91cd47ab45@embarqmail.com> Message-ID: <3d86c8e2-7ca6-109b-fda4-8dfa4c74b7ba@kanafi.org> On 4/11/2018 9:14 AM, Don Wilhelm wrote: > John and all, > > You can splice a short (3 to 4 inches) length of #12 wire to the #8 or > #10 wire and it will not have negligible voltage drop due to the short > length.

Could you reverse that and run double wire until right before the power pole and then a short single wire into the radio? That would reduce the over-all resistance in the power line and still use the single power pole jack on the radio. My power supply is a 35A Astron and I use the stock Elecraft-supplied power line. My voltage drops at least a half volt on key down.

Yes, lots of ways to skin this cat, depending on your needs and resources. Several vendors sell adapters with a "big" grey Power Pole wired with #12 pairs to four red/black connectors, and it's easy to build your own. I find #10 to be the largest cable that I can reasonably fit into the 45A insert, so I run twisted pairs of that. I've seen statements that some of the Power Pole connector boxes have undersized circuit traces on the PCB that connects them. I use them only for accessories that draw relatively low current. 73, Jim K9YC From wunder at wunderwood.org Wed Apr 11 21:43:12 2018 From: wunder at wunderwood.org (Walter Underwood) Date: Wed, 11 Apr 2018 18:43:12 -0700 Subject: [Elecraft] KX2 and SCS Pactor Modem Setup In-Reply-To: <5aceb3a0.1771c80a.8c325.de2c@mx.google.com> References: <36175022.1812795.1523495710420@mail.yahoo.com> <5aceb3a0.1771c80a.8c325.de2c@mx.google.com> Message-ID: <90F9BCAE-BF64-4D58-9732-707B24677B1E@wunderwood.org> I?ve never used an SCS modem, but it should be the same as any other data mode.

In-Reply-To: References: Message-ID: <09cec84d-c109-fe21-e81c-4dc3bf951900@cox.net> Hello all! Long time no mailing list...?? I have a nice, vintage K2,? that I want to spruce up, tune up, and bring back to it's full MOJO.?? Kind of a it's not dead yet,? it's just resting. ? Actually, it's been in use, off and on over the years,? am now getting more serious about plying the airwaves. Been looking over the various places of K2 lore, for updates and so forth,? Sverre's site, Don's, and of course the Elecraft site. First order of business ,? is it possible to have my S/N looked up??? Found a database that I don't seem to be in,? found that the Elecraft list archives go back to 2001,? but I'm not finding a post of mine in there,? so hopefully the Elecraft Records Repository would still contain it somewhere. Then I can proudly post it on the bottom of my mails, like it was done back in the day.? ;-) Next,? I have a range of boards for it, the NB, SSB, Antenna tuner, 160m antenna, and just built my long languishing KIO2 kit, to bring this K2-10 into the 21 (20th?) century. ? I have started to go thru them and see if I have all the mods and etc that should be done on them,? have done many already,? but back about '03-04.? Guess this is just a matter of looking things up,? though I have a few questions there and probably will have more. Another next,? I've been having difficulty checking to see which versions of firmware are the latest,? and what the various versions add.? Is there a version change log or something like that? Here's what I have so far,? looks like the two main ones are down a bit,? but I don't know what I'm missing,? or if I really need the updates. MCU??? 2.01f RF??? ??? 1.02 KSB2??? 1.04 ATU???? 1.03 f Here's the PCB versions marked on the boards: Main???? rev A Control rev A ATU ??? rev C (note, the board does NOT match the picture of the recent note stating some cut and jumper rework should be done on a rev C) NB and 160m? rev D SSB??? don't have,? will have to yank it to read So, the beginning of a journey.?? Will greatly appreciate whatever tips and directions I could be pointed in. Jon - KA6MOK?? K2 #????

No worries. All new releases of the Mac and Linux versions of the Elecraft Utilities will be 64-bit. As a result, OS X 10.6 (Snow Leopard) will no longer be supported and users of 32-bit Linux will need to upgrade to a 64-bit distro. This will be a gradual process as new revisions of the Utilities are released. Out of curiosity, is anyone still using OS X 10.6?

The first thing you would need to do is to make an cable to connect the tnc to the radio. I made an custom plugg of two stereo male plugs and one female. From the head phones connector i connected one side to the cable going to the tnc, and one side to the female connector for monitoring. Remember to hook up the ptt line as pactor is really sensitive to ptt timing. All molded in polymorph plastic. If anyone is interested i could make a quick write up on my blog. Then for settings. I suspect that the kx2 would be similar to my kx3. And credit where credit is due. I got this from Greg VA7BC. On radio (KX3): -MODE: USB or USB Digital -COMPression: OFF -Turn MIC gain off then gradually increase during PACTOR transmission so that 4 ALC bars are lit and the 5th bar may flash occasional. For me, MIC=3 does this -AF gain = 2 Also remember to turn off vox, and sett mic button to ptt BEFORE entering Digital mode on the kx3. I dont know with the KX2, but with the KX3 I could not change this after switching to data mode. This might have changed with software updates. I have't checked. In RMS-express select radio K3 as the dont support KX3. I dont know if this will work with the KX2. Give me a line if you have any questions or if anyone is interested in a blog post on this subject. 73 LA4TTA Erlend 2018-04-12 3:43 GMT+02:00 Walter Underwood : > I?ve never used an SCS modem, but it should be the same as any other data > mode. > > Use DATA A mode.

My old Mac Mini died when its UPS went hysterical and cycled the power violently several times. I bought a new one, complete with 16GB RAM and the 1TB Fusion Drive (and a new power backup system). My old Mini setup ran Parallels and Win7/64 so I could run several amateur radio programs on it. When I tried partitioning the new drive for 250GB for Boot camp. It wouldn't do it. There is a BUG in High Sierra that causes this and I have informed Apple of it. They have had others report the same. They had o way to fix it at the time I was having the problem in late March. My solution was to wipe the new drive and install an earlier version -- in this case 10.6 -- temporarily. The older disk utility will partition the new drive the way I needed it. After installing Win7/64, I reinstalled High Sierra and all was well. This is an example of how I had to drop back to an older O/S, if only temporarily. 73, Dave, K4TO On Thu, Apr 12, 2018 at 2:59 AM, David Fleming via Elecraft < elecraft at mailman.qth.net> wrote: > Yes..

This has worked well allowing me to get about 350 watts out of the KPA500 when driven with the KX3. After reviewing the KPA500 schematics it appears that pin 10 in the ACC cable is diode ORED with the KEY In jack so connecting the K3s via the ACC connector and the KX3 via the KEY IN RCA jack should work as before.

For example, 100 Ohms in series with 1 Ohm equals 101 Ohms net total resistance. Likewise 1 Ohm in series with 100 Ohms is still 101 Ohms. It doesn't matter if you take the voltage drop at the input or at the output end of the power run if the total load is at the end of the run. I checked with Dr. Ohm to verify this. :-) Jim - W4RKS From jthorpe at liberty.edu Thu Apr 12 11:32:33 2018 From: jthorpe at liberty.edu (Thorpe, Jeffrey) Date: Thu, 12 Apr 2018 15:32:33 +0000 Subject: [Elecraft] 32 bit Elecraft Utility Apps In-Reply-To: References: <1523510772510-0.post@n2.nabble.com> <0778CE0C-BE8E-423E-B14D-393050158BFD@liberty.edu> <5D94A1FB-ABCB-4361-8DCC-16BF772733F1@liberty.edu> <11041843.6ckDocqTPv@gantu>, Message-ID: <2D908359-DE99-43FF-B862-E6CCCD190D35@liberty.edu> KX3 Utility runs on my Pi.

First is to use DATA A - its default sideband is USB and it turns off compression and EQ leaving your normal SSB EQ and Compression settings as you choose. Secondly, using DATA A turns the MIC input into a LINE Input which will make the MIC Gain settings more mid-range. A low setting of 3 does not have very fine granularity which may give trouble setting the KX2 ALC to 4 bars with the 5th bar flashing. Also in may be better to lower the audio levels elsewhere in the system. This is basically a soundcard audio application, so the information on my website www.w3fpr.com may be helpful - on my site, scroll down the left column to the last entry and click to open that link. It has information on setting the various audio controls that may be available (set them to mid-range to start). 73, Don W3FPR On 4/12/2018 7:10 AM, Erlend Grimseid wrote: > Finally something i can help with. :) > > I have used an scs DR 7400 modem with my KX3 for some time, with great > success. > > The first thing you would need to do is to make an cable to connect the tnc > to the radio.

As for the upgrades, I suggest you download the instructions for the K2 A to B upgrade. That is only the basic upgrade. The 1st page of the instructions lists several other upgrade kits. Download the instructions for each of them to determine which (if any) have been installed on your K2. Installing all of them will give you a K2 that is almost equal to a new K2. In addition, changing the IF crystals to the current crystals will improve the filters on your K2. If you have the KSB2 board, change those crystals as well - Elecraft sells a set of 14 matched crystals for the K2 and KSB2 as well as a set of 7 for the base K2 only. While you have the crystals off the KSB2 board, it is easy to change the filter capacitors to extend the filter bandpass from the original 2.1kHs to the new 2.4kHz - the capacitor kit is SSBCAPKT. As far as firmware, upgrade the MCU and KIO ICs to the new version. The only other firmware upgrade that is needed may be the KSB2 which should be upgraded if you ever add the KPA100. The KAT2 wiring change was only valid for a short run of boards when the vendor printed the boards upside-down. Download the KSB2 PSK mod instructions to see if you have the updated resistor and capacitor changes - if not, change them. If all that is done, your K2 will perform like a new one. 73, Don W3FPR On 4/12/2018 2:28 AM, Jon wrote: > Hello all! > > Long time no mailing list...??

But if Elecraft need to chose between either 32-bit or 64-bit (and two versions obviously cost more than one to maintain), then 64-bit is the obvious choice today. /Johan, SM0XHJ From k9ztv at socket.net Thu Apr 12 12:42:12 2018 From: k9ztv at socket.net (KENT TRIMBLE) Date: Thu, 12 Apr 2018 11:42:12 -0500 Subject: [Elecraft] K1 BUILD ISSUES Message-ID: The following two issues arose during a K1 build that, while obvious to some, weren't to me, and probably wouldn't be to many . . . (1)? Even though the Errata sheet says trimmer caps C13 and C20 "may look different from what is shown", the trimmer caps shipped with recent K1 kits not only look different, they are structurally different in that they have no "flattened" side which is the indicator for how they are to be mounted.? However, continuity testing between the tuning slot (the metallic tab that the screw driver turns) and each contact leg will reveal that the leg with the continuity is the same as the "flattened" end.? I would have guessed it was the leg with the dab of red paint but I would have been wrong. (2)? At first I thought I was missing eight 0.1mf capacitors said to be labeled "104."? A strip of eight, blue, square components with no "104" was remaining in the RF board bag, and I eventually surmised they constituted the missing capacitors, although they looked different from any capacitor I had ever seen in my 58 years in the hobby. My thanks to Don Wilhelm for saving me a lot of extra work. Suspecting the K1 and K2 kits are probably not long for this Earth, I bought both last Fall with the intent of building the K1 this Spring and the K2 this summer.? A close friend talked me out of my KX1 a while back which, for some reason, resurrected an urge to build again.? I've built all the mini-modules and the big rigs, but screw-driver assembly isn't nearly as satisfying as solder-assembly. 73, Kent Trimble, K9ZTV From jthorpe at liberty.edu Thu Apr 12 12:43:43 2018 From: jthorpe at liberty.edu (Thorpe, Jeffrey) Date: Thu, 12 Apr 2018 16:43:43 +0000 Subject: [Elecraft] 32 bit Elecraft Utility Apps In-Reply-To: References: <1523510772510-0.post@n2.nabble.com> <0778CE0C-BE8E-423E-B14D-393050158BFD@liberty.edu> <5D94A1FB-ABCB-4361-8DCC-16BF772733F1@liberty.edu> <11041843.6ckDocqTPv@gantu> <2D908359-DE99-43FF-B862-E6CCCD190D35@liberty.edu> , Message-ID: I don?t remember - I?ll try to look at it tonight and see how.

I'd have to look, but I'd guess I'm getting 3-5 turns per foot, and it will vary from one end to the other.

Use *realistic* resistance values. For example, a 10 foot piece of of #8 wire (0.63 milli-Ohms per foot) with a six inch "pigtail" of #12 wire (1.5 milli-Ohms per foot) is equivalent to 11' 3" of #8 wire or less than one foot of #12 wire. The *contact resistance* in a 15A Power Pole (0.88 milli-Ohms) is, *by itself,* is equivalent to more than six inches of #12 wire. Ohm's Law is *exactly* why we would all be better off if the power jack on the K3/K3S was doubled up and the power cable replaced with #6 or #8 wire even if it were necessary to splice in some 4" pieces of #10 or #12 wire to mate with the 15A Power Pole connectors. #10 or 1/4" bolts for the power terminal with #8 wire and ring terminals on both ends would reduce the voltage drop in the power cable by 75%, if the bolted connections were torqued properly, compared to #12 wire and 15A Power Pole connectors. 73, ...

The speaker currently is designed to match the overall look of the KX3 and PX3, and accept similar third-party panels and covers as for the KX line. Presently, it uses the same legs and feet as the KX3 and PX3, and is the same height and depth as those. There is one USB port for charging the internal lithium battery, and input and output stereo jacks. The speaker is mono. The output jack redirects the right channel from the stereo input for a second speaker, just like with the Elecraft SP3 and other similar external speakers. The speaker is amplified. The SPX3 puts out a maximum of 3W, and is about as loud as any external radio speaker gets. Volume is adjusted by the KX3. It plugs into the KX3 PHONES jack. There is a built-in low pass filter to reduce noise and improve the listening experience. The prototype, as you'll see in pictures in the links below, is slightly narrower than the expected finished product. The speaker driver and on/off switch are both waterproof, but - just like the KX3 and PX3 - the case isn't. So, don't drop it in a lake. It will handle all conditions appropriate for the KX3, and is meant for indoor and outdoor use. Having matched the case design so closely to the KX3, it isn't as airtight as I'd like it, so the next prototype will have the case halves join in a more customary way, but remain the same dimensions and overall look. This will also improve ingress protection. You'll see the speaker is not a polished finished product yet, as it's a rough first prototype made by hand. Your feedback will assure the final product is what you want gracing your portable shack. Please note, the KX3 in the photo is only to demonstrate the speaker. All feedback is welcome. Please let me know which reasonable enhancements or simplifications you'd like to see. Examples: * Would you want an output USB port to use the speaker to charge your phone? * Would you want to dispense with the built-in battery, and run it entirely from external power? * Would you want a second passive speaker driven by the first to save on weight and cost? That is, a SPX3A (active, with battery, charger, and amp) and SPX3P (passive, with only speaker driver) * If you're a KX2 user, would you like me to produce the SPX2 (also in development)?

OTOH, the K2 is around and selling for just as long as possible. Procurement of thru-hole components becomes more difficult as manufacturers are switching to all SMD components. So far Elecraft has been able to provide suitable substitutes such as the SA612 IC mounted on a carrier board so it can be used in a thru-hole board. Other such substitutions will be coming in the future, but Elecraft is dedicated to keeping the K2 kit alive for as long as possible. 73, Don W3FPR On 4/12/2018 12:42 PM, KENT TRIMBLE wrote: > Suspecting the K1 and K2 kits are probably not long for this Earth, I > bought both last Fall with the intent of building the K1 this Spring and > the K2 this summer.?

Those range from 52 to 72 turns per meter or 1.94 to 1.38 cm per turn. That works out to 15 to 22 turns per foot. Yes. This is done to minimize inductively coupled crosstalk between pairs, which is critical to Ethernet transmission. A pair from CAT5/6 cable used to carry audio or RF provides very good rejection of differential mode coupling to/from the cable. It's a great choice for telephone wiring if RFI to the phone line (including DSL) is a problem. A CAT5/6 pair is also a great choice for adding a ferrite common mode choke to a low band receive antenna. I've completed a set of measurements on this and will publish an applications note in the near future. 73, Jim K9YC From kl7uw at acsalaska.net Thu Apr 12 14:11:44 2018 From: kl7uw at acsalaska.net (Edward R Cole) Date: Thu, 12 Apr 2018 10:11:44 -0800 Subject: [Elecraft] Astron VS-35M Powwer Supply V- Message-ID: <201804121811.w3CIBl6F025658@mail42c28.carrierzone.com> I run all my 12v equipment (almost anyway) on a 50A Astron PS. Since the PS is rack-mounted in a half-height cabinet the dc cable is about 12-foot long, so I used #4 welding cable that terminates on a 30A Fuse holder. That feeds two HD barrier strip terminal blocks (for pos and neg rails). The terminals accommodate No. 10 awg cables to the heaviest current loads. A secondary strip handles small stuff (under 5A total). The PS runs 13.71v and drops to 13.5v at the fuse holder. K3 sees about 13.35v (radio is 10w version). I have only two PowerPole equipped pieces; the rest use terminals or other connectors like Molex, etc. (even one Cinch-Jones). I count 14 loads connected to the 13v power distribution (not all are used simultaneously). In the case of running to a regular-sized PP connector I just add a few inches of no.14 awg (splice is two wires soldered and covered with heat shrink) 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From jhpike at cox.net Thu Apr 12 14:25:54 2018 From: jhpike at cox.net (Jon) Date: Thu, 12 Apr 2018 11:25:54 -0700 Subject: [Elecraft] K2 - Revival of a resting one...

For example, 100 Ohms in series with 1 Ohm equals 101 Ohms net total resistance. Likewise 1 Ohm in series with 100 Ohms is still 101 Ohms. It doesn't matter if you take the voltage drop at the input or at the output end of the power run if the total load is at the end of the run.

After exhausting the ideas suggested in this thread, I did have to send my KX2 to Elecraft for service. They determined the issue was "U20, U22 drivers for PA at fault." Looking at the schematic, these two components appear to drive the final FETs. Does anyone have any ideas as to what may have caused this failure? It's not clear to me whether a high SWR could have provoked this. Note: U20 and U22 are located on schematic "Assembly E850729", Sheet 3 of 4. It has these as SGA7489, but this part may be discontinued. Elecraft replaced both of these with part E600447/ GALI-84+. 73, Chris (KD2FLH) On 03/25/2018 12:35 PM, Don Wilhelm wrote: > Chris, > > That high SWR indication along with the HI CUR warning usually means > that there is no antenna or dummy load electrically connected. > Check the cable from the KXAT3 to the BNC jack to be certain it is > properly seated. > > Did you ever connect an old 75 ohm BNC connector to the KX3??

There are 100's of 1000's of us out here with older hardware, happily running current 32 bit os's such as Mint 18.x 32 bit, and all works fine. Why follow the MS/Apple flock of sheep, just because they are moving to 64 bit systems? There is no advantage for 99.9% of users, to move to a 64 bit OS, whatever the flavor. The hardware wont support the oft quoted 10's of GB of RAM (even if the CPU might.)?? Plus, for the ram we've got, with the system maxed out (be that 4, 8, 12 or more GB) any given app takes twice the space compared to 32 bit code, same with the storage. It's marketing BS foisted on us by the likes of MS and that Fruit company. Plus you then have to load 32 bit compatibility tools in some OS's, to carry on running the software you have! So why bother... As to the K3/KX3 utility, well, the transfer to the radio is over an 8 bit wide path.? Need I say more. 73. Dave G0WBX. From WA7WJR at hotmail.com Thu Apr 12 18:20:05 2018 From: WA7WJR at hotmail.com (BJ ROLLISON) Date: Thu, 12 Apr 2018 22:20:05 +0000 Subject: [Elecraft] Elecraft Digest, Vol 168, Issue 14 Message-ID: First, just to be transparent I worked as an software engineer at Microsoft for 20 years. I agree there is sometimes no need for some users to move from a 32-bit system, to a 64-bit system. For example, if you have a computer dedicated in your shack, and mostly run apps for amateur radio or the internet, do not do run multiple programs simultaneously and switch between them frequently or do a lot of code crunching or image processing than you may not need a 64-bit machine. Also, since it is very unlikely that most amateur radio apps will likely be ported to 64-bit anytime soon. However, there is tremendous advantage of a 64-bit system over a 32-bit system for many users who use their computers for more complex operations besides running a few limited apps and browsing the web. Simply put, a 64-bit system will process large amounts of data through RAM more efficiently compared to a 32-bit system. In layman's terms that means that searching a large database of QSO's will take less time; especially if you have other apps running in the background. While a 64-bit system will use more memory space compared to a 32-bit system; it is false to say the space is 2x more. The 64-bit system also allows users to exceed the 4Gb limit of 32-bit systems. And many modern apps are memory intensive. Also many users who multi-task apps on their computers, use memory intensive programs (photo processing, code crunching, etc.) or use browser apps that are constantly auto refreshing, will greatly benefit from a 64-bit system. Also, while a 64-bit system will use 4GB of RAM more effectively, I personally would not recommend anything less than 8GB of RAM.

It didn?t occur to me when I installed it that it shouldn?t run due to the different architecture. Turns out that the first thing I installed to the fresh installation of Raspbian was Exagear Desktop to test with a different application (a windows one.) I had thought that you had to tell ED to start the 686 emulator prior to running an x86 app, but it appears to automatically invoke when it detects the different architecture trying to load.

A 32-bit compatibility layer is needed. It is essentially an entire copy of the 32-bit version of the OS installed in parallel. On most Linux distributions this needs to be installed manually. On Windows the compatibility layer (WoW64) is installed by default on desktop versions and some server versions. The 32-bit support is possible because Intel and AMD is still including the 32-bit instruction set in the current CPUs. When they decide that space is needed for more import things (or causes too many security issues) and remove it, it will no longer be possible to run 32-bit applications on those CPUs. Users with old computers can still run the older version of the Elecraft utilities so it isn't like anything will stop working. By the way, if you get errors when the K3/KX3 utilities is checking for new firmware, try installing the 'curl' package. /Johan, SM0XHJ On 2018-04-13 05:53, tomb18 wrote: > So forgive me but is it the case that the 32 bit elecraft utilities > will not run on 64 bit operating systems??If that's the case then > elecraft will release a 64 bit version of the utilities.

Morris Sent: Thursday, April 12, 2018 1:06:25 PM To: elecraft at mailman.qth.net Subject: [Elecraft] [KX3] New Product: SPX3 External Speaker I've built a prototype powered external speaker for the KX3, and would like some feedback on what folks would desire in terms of features, and whether folks would want to own one. The speaker currently is designed to match the overall look of the KX3 and PX3, and accept similar third-party panels and covers as for the KX line. Presently, it uses the same legs and feet as the KX3 and PX3, and is the same height and depth as those. There is one USB port for charging the internal lithium battery, and input and output stereo jacks. The speaker is mono. The output jack redirects the right channel from the stereo input for a second speaker, just like with the Elecraft SP3 and other similar external speakers. The speaker is amplified. The SPX3 puts out a maximum of 3W, and is about as loud as any external radio speaker gets. Volume is adjusted by the KX3. It plugs into the KX3 PHONES jack. There is a built-in low pass filter to reduce noise and improve the listening experience. The prototype, as you'll see in pictures in the links below, is slightly narrower than the expected finished product. The speaker driver and on/off switch are both waterproof, but - just like the KX3 and PX3 - the case isn't. So, don't drop it in a lake. It will handle all conditions appropriate for the KX3, and is meant for indoor and outdoor use. Having matched the case design so closely to the KX3, it isn't as airtight as I'd like it, so the next prototype will have the case halves join in a more customary way, but remain the same dimensions and overall look. This will also improve ingress protection. You'll see the speaker is not a polished finished product yet, as it's a rough first prototype made by hand. Your feedback will assure the final product is what you want gracing your portable shack. Please note, the KX3 in the photo is only to demonstrate the speaker. All feedback is welcome. Please let me know which reasonable enhancements or simplifications you'd like to see. Examples: * Would you want an output USB port to use the speaker to charge your phone? * Would you want to dispense with the built-in battery, and run it entirely from external power? * Would you want a second passive speaker driven by the first to save on weight and cost? That is, a SPX3A (active, with battery, charger, and amp) and SPX3P (passive, with only speaker driver) * If you're a KX2 user, would you like me to produce the SPX2 (also in development)?

I worked for CDC Sunnyvale Ops back in the early 1970s and part of that time I was briefly working on the FTN (aka Fortran) compiler, Pass 1. The regular floating point on the 6600 was 60 bits as the word size on the computer was 60 bits. The failing memory part ? I believe that the FTN compiler itself implemented double-precision 120 bit floating point that was a slight sacrifice of screaming performance (at the time) for higher precision. I think this was FTN?s type G floating point. So, this floating point did not have 120 bit registers but rather treated two 60-bit words each holding half of the floating point double-precision number. Also the CDC 6600 was released in 1964. SN1 of the CDC 6600 was originally sent to Los Alamos labs but retired to Sunnyvale when I worked there (?72-75) and it was our main 6600 used by the FTN compiler project. Of course we had at least once each of all the 6000-series computers as well as a 7600. 73, phil, K7PEH > On Apr 13, 2018, at 12:48 PM, brian wrote: > > My failing memory seems to recall that the CDC6600 used 60 bit math for floating point single precision operations. > > https://en.wikipedia.org/wiki/CDC_6600 seems to confirm that. > > They were great machines, till the 7600 then the Cray computers showed up... > > It was interesting to bring these machines to their knees by physics calculations that took days to run.

Morris Sent: Thursday, April 12, 2018 1:06:25 PM To: elecraft at mailman.qth.net Subject: [Elecraft] [KX3] New Product: SPX3 External Speaker I've built a prototype powered external speaker for the KX3, and would like some feedback on what folks would desire in terms of features, and whether folks would want to own one. The speaker currently is designed to match the overall look of the KX3 and PX3, and accept similar third-party panels and covers as for the KX line. Presently, it uses the same legs and feet as the KX3 and PX3, and is the same height and depth as those. There is one USB port for charging the internal lithium battery, and input and output stereo jacks. The speaker is mono. The output jack redirects the right channel from the stereo input for a second speaker, just like with the Elecraft SP3 and other similar external speakers. The speaker is amplified. The SPX3 puts out a maximum of 3W, and is about as loud as any external radio speaker gets. Volume is adjusted by the KX3. It plugs into the KX3 PHONES jack. There is a built-in low pass filter to reduce noise and improve the listening experience. The prototype, as you'll see in pictures in the links below, is slightly narrower than the expected finished product. The speaker driver and on/off switch are both waterproof, but - just like the KX3 and PX3 - the case isn't. So, don't drop it in a lake. It will handle all conditions appropriate for the KX3, and is meant for indoor and outdoor use. Having matched the case design so closely to the KX3, it isn't as airtight as I'd like it, so the next prototype will have the case halves join in a more customary way, but remain the same dimensions and overall look. This will also improve ingress protection. You'll see the speaker is not a polished finished product yet, as it's a rough first prototype made by hand. Your feedback will assure the final product is what you want gracing your portable shack. Please note, the KX3 in the photo is only to demonstrate the speaker. All feedback is welcome. Please let me know which reasonable enhancements or simplifications you'd like to see. Examples: * Would you want an output USB port to use the speaker to charge your phone? * Would you want to dispense with the built-in battery, and run it entirely from external power? * Would you want a second passive speaker driven by the first to save on weight and cost?

I appreciate it very much. I guess I didn't make it clear enough in the long description. The SPX3 already has support for exactly what you're requesting. Just like the Elecraft SP3 and other similar desktop radio speakers, it splits the right channel and sends it out the left channel of the output stereo jack. The right channel of the output is unused. (or did I split off the left channel? same difference) That way, two identical speakers can be used in stereo when daisy-chained. Since the SPX3 tilts to have the driver cone aimed up at an angle, I find it more easily puts my ears in the listening sweet spot than having to prop up a forward facing speaker on a shelf. At any rate, the dual watch and stereo effects features of the KX3 can be enjoyed using a pair of SPX3s; likely as SPX3A and SPX3P. Also, the amplified SPX3 or SPX3A can be powered externally, with or without the internal battery. This brings us to a big question. Should I sell the SPX3A and SPX3P as a pair, or separately?

I apologize in a advance for others who post replies without getting a response from me. If the list server doesn't send me a copy, I may not spot it in the archive. The original message is at the bottom. First is my reply: Hi Walter, Thanks for your feedback. I appreciate it. Yes, I'm aware of that amplifier. It would be appropriate for driving bookshelf HiFi speakers, as your writeup demonstrates - cool project, by the way. Aside from 15W being overkill for driving the 2W/3W driver in the SPX3, it wouldn't fit in the enclosure, and would need to be modified by hand to work as needed even if it did fit. Most transceiver external speakers put out 2-3W, as that's all that's necessary for listening to voice and CW at close range. Plus, when taking the SPX3 portable, it needs to last a long time on a battery. 15W per channel (30W) would drain a battery mighty quick. I turned the prototype on this morning when I got up, and it's still running after more than 15 hours on the same battery charge. The SPX3 sports features specific to what the KX3 needs, such as a low pass filter, built-in battery and charging circuitry, a shielded enclosure to eliminate RF from the antenna affecting the audio, works great outdoors, the speaker cone won't get damaged if it gets wet, and more. Plus, it matches the KX3 and supports KX panels and covers (already in talks with the SIDE KX folks). You might want a pair yourself to take on the road. Thanks and 73, Robert (AG6ZZ) --- Walter Underwood [1] Fri, 13 Apr 2018 11:58:12 -0700 [2] I use this 12 V audio amp. It would be easy to put it inside a speaker. It seems to vary in price a bit.

I turned it on this morning and the display was completely blank, fully lit as in not dark. It stayed blank for a bit so I turned it off. When I turned it back on, some pixels were dark but it was mostly blank. I cycled power again and it came back to normal state. This is of course, Saturday, and home base is not available. Has anyone seen this before and can point me to something I can do while waiting for home base to open Monday. The radio has the following options: K3EXREF, K144XV and the module tying the K144XV to the K3EXREF controlled synthesizer. A second problem has also surfaced, the blinking asterisk indicating that a suitable signal from the external 10 MHz source is not making it into the system. The 10 MHz source is OK as it works fine with another K3. There must be a connection problem inside the radio. Unless there is something I need to do to enable it that I missed. Again, this is a 10 watt K3S.

You can still record CW messages for CW and DATA modes if you switch to that mode. Or, you can use the CW message entries available in K3 Utility. If recording for possible use with DATA modes, put a "|" character at the end of the text. It will be ignored for CW, but on DATA modes it will cause an immediate return the receive without a 4 second "diddle" time. You may use K3 Utility to store CW and DATA mode messages if your CW keying is not perfect. The M1-M4 buttons can also be used for frequency, mode, etc. storage and retrieved with a M>V button then a tap on the M1-M4 button. I use the M1 button to store a frequency and mode for CW in the middle of the CW band segment, M2 for a frequency in the SSB band segment and M3 for a frequency in the DATA mode segment. I reserve M4 for a frequency I run across while scanning the band and record any frequency I want to return to quickly. Those are per band memory buttons. The frequency, mode M1-M4 buttons do not interfere with the use of the buttons for retrieving message storage. 73, Don W3FPR On 4/14/2018 4:35 PM, Michael Blake wrote: > I do not have the DVR option in my K3s but have used two of the buttons, M1 & M2, as programmable macro buttons.

The USB jack is for a keyboard. That means there is no way to connect a large monitor. The P3 (used with the K3 and other radios with an IF output) does have an option to use an SVGA monitor, but that operates from the transceiver output, not the RX IQ baseband signals. You can however connect the RX IQ output to a computer soundcard and the KXUSB to run a panadapter application on the computer. NaP3 and Win4K3 are two, HDSDR may be another. If you then interface your computer with an HDMI monitor, then you may have what you want. I know the capability exists, but I am not currently using those applications. If you have trouble with setup or operation, consult the forums for that particular software. 73, Don W3FPR On 4/14/2018 5:09 PM, Jack Seymour wrote: > I may have missed the latest update of this but has there been any progress > on using an external monitor via HDMI to connect to the PX3 (own a KX3 and > hope to soon have a PX3)?

If the AGC is not functioning, strong signals can overload the receiver. Motorboating can be because of the batteries - normally happens only when the batteries are near discharge. Try an external supply or brand name new alkaline batteries and see if it goes away. Don W3FPR On 4/15/2018 12:08 PM, hmmjr wrote: > I recently bought a used KX1 with 4 bands and the ATU.?

Slides 213-214 in http://k9yc.com/KillingRXNoiseVisalia.pdf show a small one that I bought to run a laptop in W6GJB's truck for mobile contesting.? This is the smallest model in their Pure Sine Wave series, and it's much quieter than larger models in the same series, which are too noisy use close to antennas. For others who suggested other DC chargers -- all forms of Li batteries can easily be damaged if not charged per their design specs. Unless you know those specs and can be certain to conform to them, stick with the "official" charger. 73, Jim K9YC From tf3y at tf3y.net Sun Apr 15 17:26:39 2018 From: tf3y at tf3y.net (Yngvi (TF3Y)) Date: Sun, 15 Apr 2018 21:26:39 +0000 Subject: [Elecraft] Charging Lithium Ion batteries (KX2) from Car In-Reply-To: References: Message-ID: Thanks Jim.

Here's are some requested features: 1. One stereo channel to speaker driver and another channel to output jack (already in first prototype) 2. 12V input (planned is 9-15V, like the KX3) 3. Separate powered (active) and unpowered (passive) speakers The reasons I've gotten for this is that it would save on the weight of and inconvenience of charging a second battery 4. Separate volume controls for the internal speaker driver and the output jack The reason I've gotten for this is that a computer will need the volume set separately from the speaker. Some have stated the computer's software can adjust the gain on the input, and that there only needs to be one volume control for the speaker driver. I'll need consensus on this from the digital mode folks. 5. USB power output This would be convenient for those who wish to use their speakers as phone chargers. Things to consider: A. Making two different speakers substantially increases manufacturing costs for the most expensive part; the enclosure. Since most folks will be fine with just one speaker, then the lower production numbers of the passive speaker would make its per unit cost much higher than the active one. However, folks would expect a lower price on the passive one. So, I'd have to sell them as pairs to justify manufacturing the passive ones, which would mean a higher cost to consumers who only want the active one. It would also increase the cost to those who want both because of the two different enclosures instead of just one enclosure twice. B. The one issue which would force making both an active and a passive speaker is the need stated by some respondents that the active one would require a second volume control for the output to the computer for digital modes. It would be expensive and time consuming for me to try every digital mode software on every operating system, so I need confirmation whether this is truly necessary. C. If a second volume control is not truly necessary, then that simplifies things tremendously. I'll wait for consensus on this before going into why. D. A USB power output port is beyond the scope of the speaker's intended utility. Also, it would draw down the battery at the cost of significantly limiting how long the speaker could be used before needing a recharge. Furthermore, the extra hole and port would increase the cost while reducing ingress protection. Lastly, there's not much room in the small enclosure to accomodate nonessential items.

The KXSPA should connect to the left channel since that is the channel that is normally used by soundcard digital. I think that means you would want to provide a knob controlled gain control on your active speaker so the sound level to the speakers can be controlled without disturbing the level to the soundcard being used for digital modes. 73, Don W3FPR On 4/15/2018 11:40 PM, Robert Morris wrote: > First of all, I want to say thanks to everyone for all the great > feedback I've been getting on the speaker.

I'm hoping one volume knob will do the job for everyone else too. Plus, if the KX3 puts out enough signal for the PC, then you don't really want an amplifier in the signal path. I want to be sure about the channel which needs to go to the sound card. Are you saying the left channel from the KX3 is the one the computer needs, or are you saying the computer needs the signal to be present on the left channel of its input? If it's the latter, then that is already how the SPX3 is wired. For the first prototype, the stereo output of the KX3 goes into the SPX3 input port, then is split. The left channel goes to the amplifier, and the right goes to the left channel of the output port. Will that do the job, or does the computer really need the signal which originated from the left channel of the KX3? I don't see in the KX3 manual where it specifies which channel the digital mode signal is output. I had assumed it would be on both left and right channels.

If the 32 bit utilities? do run on a 64 bit OS then what's the point??There is no point. A 32 bit version of their utilities will work just as well as just fast over a rs232 connection no matter if the OS is 64 bit 128 bit or 256 bit.?So the question is will these utilities not run on a 64 bit OS? They are 32 bit and run just fine on 64 bit windows..?73 Tom? The 32bit code on 64bit system problem varies by OS.? Windows(64) generally has good support for 32 bit applications.? (Most of the more esoteric background system tools are 32 bit code anyway, some are still virtually the same as those developed for Windows 2000, or even NT!) But these days MS has no support for 16 bit software, such as Windows 3.xx code etc (not exactly surprising, but the old Win3x "Terminal" program is still quick and easy to use, for example, on an old XP box.) ? Windows 32 bit systems, XP and earlier, fully support the old Win3x software, and many DOS programs too.?? (Vista and later dropped 16 bit support, even on the command line.) In the Linux world, it's utterly different.? From my personal experience, a pure 64 bit system will not run any 32 bit code "as is", unless you hunt down and load a sort of compatibility layer.?? Much as in the later days of Windows 3.xx, you'd use a 32 bit compatibility tool, to run some 32 bit code on a 16 bit system!?? Some systems come with that already, but it needs enabling. So, if you go to a 64 bit Linux, unless all the programs you want are freely available in that OS's 64 bit flavours, you'll have to compile them yourself.? And that too, can be troublesome for some older (and not so old) Ham software, where the original author has "handed off" support to the "community."?? Also, some of the compilation tools that a lot of the older (but still very good) code needs so you can build it, have not yet been updated to "64 bitness" themselves. Plus, as before, though "64 bit" CPU's have been around for a long time now, many of the class of machine that most of us would "recycle" (Ex Vista era or later laptops etc) and put Linux on, other than the internals of the CPU, are in truth 32 bit machines, and as such will have memory addressing issues above 4Gig. Even ex XP machines, running 32 bit versions of Lubuntu, LinuxLite, or Puppy Linux, can have very useful roles in a ham shack, for (other than time) next to zero cost. If however, you want to edit/mix real-time HD video and audio on a PC.? Then, a fast 64 bit system will probably be needed.?? The other "maybe" need, is if you run a pure SDR based station, and need to run various digimodes all on the same PC, with multiple screens and I/O systems.?? But I know of other people already doing all that on 32 bit Linux systems just fine anyway.? (Once they find out how to make it all work and play nice.) Plus as before, the K3/KX3 utility, only communicates to the radio over an 8 bit link, & that is not in the MBPS range. I have no experience of Apple products, other than on odd occasions having to reconfigure the XYL's iPad WiFi settings. 73. Dave G0WBX/G8KBV (Who does use Windows 7 Pro 64 bit at work, but I'm 95% Linux at home now.) PS: The fix for this, is to release the K3/KX3 utility sources into the public domain.?? Then if you want, you can compile it on a 32, 64 bit (or other) system where a compatible compiler exists. ? Any Elecraft "secret sauce" could probably be reverse engineered from the existing tool today, by recording and examining the data passing between the rig and utility, for known tasks.? (I'm thinking of the firmware update procedure etc, all the other stuff is documented in the manuals.) >><< -- Created on and sent from a Unix like PC running and using free and open source software: From donwilh at embarqmail.com Mon Apr 16 07:50:44 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 16 Apr 2018 07:50:44 -0400 Subject: [Elecraft] [KX3] New Product: SPX3 External Speaker In-Reply-To: <437f3e02a50b48269df572fadae4215b@iloc.com> References: <72736a47-76da-4582-2cda-c09b0605298f@embarqmail.com> <437f3e02a50b48269df572fadae4215b@iloc.com> Message-ID: <94f99ee8-975b-203c-f1f3-0b857c93445e@embarqmail.com> Robert, It is not the KX2/KX3 that decides which channel from the soundcard is used, but the PC application software.?

This is an easy one. I'll just send both channels to the output port, but reversed, so the right channel still becomes the left for the second speaker. Since they're both carrying the same signal, it doesn't make any difference to the computer. Only the left channel goes to the amplifier. I'll put both input and output ports on the second speaker as well, so both can be connected at the same time as the computer. Since they'll both have on/off volume controls, either can be muted by turning it off. The on/off volume controls don't affect the signal passing through the input and output ports; just what goes to the speaker driver. So, this change means I'm back to amplifying each speaker individually. To save weight and the inconvenience of charging two, both can be powered externally without the internal battery installed. Also, if folks would prefer it, I could put a power output port on the speaker, and include a speaker-to-speaker power cord so that the battery in one could power both for folks taking them portable. Or will folks taking them portable be taking just one?

If you read carefully, you will find it applies to the "station ground" which may be a separately driven ground rod - which for your safety and that of your family and pets as well as your equipment and also to comply with NEC requirements, that separately driven ground rod MUST be connected to the electrical entry ground rod by a #6 or larger copper wire. If your shack ground rod does not comply, dig a trench for the wire and make that connection outside the building. The only exception is if the two ground rods are more than 100 feet apart. 73, Don W3FPR On 4/16/2018 8:38 AM, Charlie T wrote: > "This greatly increases the chances for damages to station equipment and all other electronic equipment in the household in event of a lightning event." > > What is, disconnecting the wire or leaving it in place? > Your comment can be taken both ways. > > 73, Charlie k3ICH > > > > > -----Original Message----- > From: elecraft-bounces at mailman.qth.net On Behalf Of Joe Subich, W4TV > Sent: Monday, April 16, 2018 8:11 AM > To: elecraft at mailman.qth.net > Subject: Re: [Elecraft] Issue 12 re Astron Power Supply > > On 2018-04-15 10:38 PM, hawley, charles j jr wrote: >> I disconnected the black wire.

What are you - a lawyer? Connecting the station ground (bonding) and the entry ground to the power system safety ground at other than the power meter (power system entry point) greatly increases the chances for damage. It is also (as nearly as I can tell and I am not a lawyer) a violation of the National Electrical Code and most local building codes (which incorporate NEC). Consult an electrical contractor and/or code enforcement officer to be sure, but my understanding of the rules are that the ground conductor of all cables (e.g. coax shields, etc.) entering the home must be bonded to the electrical system ground (at the electrical entry). If the entry points are separated, all subsidiary entry points must be bonded to the electrical system ground using a large cable *external* to the building. 73, ...

That is proper grounding and bonds all entry points together *OUTSIDE* the building to prevent grounds from separating. It creates a common "island" for everything inside the building. However, for the majority of amateur stations which fail to properly bond the shields of all of the coaxial cables entering the shack to the electrical system ground *at the meter*, there is no "island" ... more like an isthmus across the equipment. 73, ...

If you mount them on the bottom, you will have trouble trimming the leads for one thing. When snugging the wires down, tighten the one where the tinned wire lead comes closest to the edge of the crystal case so it can't make contact. If you scraped the wire insulation while winding the toroid, rewind it. That was the problem in those old posts - scraped enamel insulation. 73, Don W3FPR On 4/16/2018 10:16 AM, Mark Petrovic wrote: > Hi.

Yes, a good ground rod system is for lightning protection. I have a grounding system in place at my house with a driven stake at each place where the perimeter wire connecting them make a 45 degree turn or more. That is also connected to the Utility Entry Ground rod. If you are fighting audio noise, hum and buzz problems (now that we have low level audio stuff in the hamshack) - disconnect that wire AND bond all enclosures together as K9YC suggests. We have the "pin 1" problem in modern ham gear. In olden days, it was not a problem because connectors were mounted on the enclosure metalwork, and any pickup of hum, buzz and noise was conducted on the 'outside' of the enclosure and away from thee signal lines on the inside. Today's practice is to mount those connectors directly to a PC board where any hum, buzz and noise will be conducted onto the PC board ground plane where it will couple to the signal PC traces. For purposes of hum, buzz and noise reduction, that Power Supply should be cut and the enclosures in the system bonded directly together (not each to a single point ground). Remember that this bonding and grounding will NOT help with RF problems - those are taken care of with good common mode chokes in the antenna system to choke off current on the outside of the coax shields. 73, Don W3FPR On 4/16/2018 9:28 AM, George Danner wrote: > Re-Connect it! > >> From a broadcaster (AM,FM & TV) was in South Florida (lightning >> capital of > North America). > > The more massive the common (ground, bonding, whatever term you use) for > the connection between equipment and the power company ground connection > the better. > We even used ring grounds around studio & transmitter building with > ground rods every 10' all cad-welded.

Running FT8, it has a lot of computing to do to decode the signals in the 3 second or so window it has. It is decoding multiple signals, and then reconstituting the decoded signals so it can subtract them from the input and decode the signals hiding underneath them. Joe Taylor mentioned in a lecture that the decoded signals are listed in ascending order of frequency, and these second decodes appear at the end. OTOH, wsjt-x appears to only need about 30MB of storage, so it should fit nicely in the 2GB address space it has on most OSes. It needs speed, not bit addresses. BUT, with Linux distos moving away from 32 bit, and Apple announcing the end of support for 32 bit, if Elecraft wants to continue supporting these platforms -- and I hope it will -- they should move "with all deliberate speed" to supporting 64 bit utilities. 73 Bill AE6JV On 4/16/18 at 1:39 AM, elecraft at mailman.qth.net (Dave B via Elecraft) wrote: >If however, you want to edit/mix real-time HD video and audio on a PC.? >Then, a fast 64 bit system will probably be needed.??

With the equivalent of 50 feet of power cable (4 connectors plus a 10 foot physical cable), I would not be surprised. Assuming 20A in transmit (on 15A power poles!), a 1V drop represents 0.05 Ohms of total circuit losses .... that's pretty good for 10 feet (x2) of cable plus eight connectors (4 in the + lead, 4 in the - lead) and the switching device (probably a Schotkey diode). However, the 0.05 Ohms in the negative lead is probably ten times higher than in a braided bonding connection directly from the K3 chassis to the power supply chassis. I'm surprised that only 75% went through the ground path - that indicates the ground path has 1/3 as much resistance as the "right" (V- lead) path. 73, ...

There are 6 points of contact. The APP contact to the rigrunner itself (2 contacts, the negative must be considered as well). There are 2 at the fuse contacts, and there are 2 at the the cable connecting the output of the Rigrunner. Add an additional 2 for the connection to the K3 - that makes a total of 8. If you consider a 1mohm contact resistance (a practical estimate), then you have an 0.008 ohm resistance between the power supply and the K3. At 17 amps current draw for a K3 at 100 watts, the expected IR drop with that configuration is 0.136 volts due to contact resistance alone. Add to that the resistance of the wire (#12 wire at 20 degC of 1.558 ohms per 1000 ft.), you have an additional 3.116 milliohms resistance in a 5 foot cable of #12 wire - for a total of over 1.0 volts from the #12 wire. In other words, the total contact resistance of the 8 powerpole connectors is not as great as the resistance of 5 feet of #12 wire. Yes, connect the the K3/K3S directly to the power supply for best results, but if you connect through a Rigrunner,, expect some added voltage drop. The voltage drop through properly assembled APP connectors is low but not zero. 73, Don W3FPR On 4/16/2018 4:51 PM, Joe Subich, W4TV wrote: > On 2018-04-16 4:26 PM, hawley, charles j jr wrote: >> So 4 sets of power pole connectors plus 2 fuses. > > Even if the power pole connectors are assembled perfectly and > mated with optimum tension, the resistance in just the four > (15 A) power pole connectors in the negative lead is equivalent > to nearly 40 feet of #12 copper wire! > >> The voltage at the rig, K3, now drops a volt when putting out 100 >> Watts. > > With the equivalent of 50 feet of power cable (4 connectors plus a > 10 foot physical cable), I would not be surprised.?

Cost-wise, it would be less expensive to add another ?A? model to serve as a second [passive] speaker (albeit with the amp turned off, with a bypass for the direct feed from an external source). This would only require the ?A? model to be switchable to either L or R input (a channel swap DPDT)?and be able to go into bypass [through] mode Although it may seems wasteful to have a 2nd active speaker doing duty as a passive one, but it would be less expensive to implement (both for producer and user), and, hey, you?d have the utility of having a 2nd active speaker kicking around in your kit (for whatever:) As an incentive [sweetener], Robert, you could offer a discount on ordering a second ?A? speaker at time of purchase Addendum: if you only made one model, an SPX3A, to pair with the KX3, as a KX2 user I would be willing to lump it and purchase them anyway? ?cuz, Elecraft <3 FB es 73 de KX2CW Joan kn Darmok and Jalad at Tanagra, said Piglet.

Making two different speakers substantially increases manufacturing costs for the most expensive part; the enclosure. Since most folks will be fine with just one speaker, then the lower production numbers of the passive speaker would make its per unit cost much higher than the active one. However, folks would expect a lower price on the passive one. So, I'd have to sell them as pairs to justify manufacturing the passive ones, which would mean a higher cost to consumers who only want the active one. It would also increase the cost to those who want both because of the two different enclosures instead of just one enclosure twice. > > B. The one issue which would force making both an active and a passive speaker is the need stated by some respondents that the active one would require a second volume control for the output to the computer for digital modes. It would be expensive and time consuming for me to try every digital mode software on every operating system, so I need confirmation whether this is truly necessary. > > C. If a second volume control is not truly necessary, then that simplifies things tremendously. I'll wait for consensus on this before going into why. > > D. A USB power output port is beyond the scope of the speaker's intended utility. Also, it would draw down the battery at the cost of significantly limiting how long the speaker could be used before needing a recharge. Furthermore, the extra hole and port would increase the cost while reducing ingress protection.

If all the devices run from the same 12V power supply and they are all bonded together, then there is nothing to prevent some of the transceiver return current flowing in the negative power supply leads of the other devices. Hopefully the transceiver power leads use much heavier wire so most of the current will flow in them. And if the plus and minus leads are close together and tightly twisted then that should reduce hum and noise coupling. Ideally every device would have its own 12V power supply, each with floating ground. Then there would be no "ground loop". (Sorry Jim, I know you don't like that term.)

I don't want to seem to be arbitrary in my decision making, which is why I wrote the cost-benefit analysis. Also, I want folks to have a chance to let me know what's most important to them and inform me of anything I may have overlooked or am not as studied on as themselves. The bottom line is, what best serves the users is the best product to produce. At present, I'm leaning toward creating just the SPX3 with the following features: 1. 12V (9-15V) DC input with same power input jack as the KX3. 2. Internal, removable, Lithium battery 3. Operable with or without battery when connected to external power 4. Power cable with input plug at one end, and no connector at the other 5. Optional power cable with input plug at one end, and PowerPole at the other 6. 3.5mm (1/8") Stereo input 7. Left input channel to amplifier for speaker driver 8. Reversed Left and Right channels passed to 3.5mm (1/8") stereo output, unamplified 9. 2W (3W max) to speaker driver 10. On/Off volume control. This only affects amplifier and speaker driver; not pass through to output 11. 3.5mm (1/8") Stereo cable with two L male ends. Items 1, 4, 5, and 10 are what will be new in comparison to the first prototype. Since the KX2 and KX3 have the same look and feel, the SPX3 would certainly look natural next to either, even though it would be as tall and deep as the KX3. I'll have to see whether there is demand for a smaller SPX2 before embarking on it. It would have the same parts stuffed into a smaller enclosure. Adding a switch to make a speaker flip between active and passive would require a second switch to determine whether the output would be amplified, or a triple throw switch. After all, when connected to a PC, the output would not be amplified, but it would be active in order to power the internal speaker driver. Adding such a switch, which would be an entirely new feature for a speaker, would add cost and complexity, and likely cause confusion. It would be much simpler, cheaper, and straightforward to power the second speaker with a separate cord. I could put a power output port on it so that a power cord could pass from one speaker to the other, allowing both to be run from the same battery. However, if someone is really bent on saving weight and consolidating the power source, then it seems to me that person would simply remove both batteries and power both externally. In all honesty, the battery doesn't really weigh that much more than a power cord, is nicely tucked away inside the speaker, and doesn't need to be connected up along with all the other cords when operating in the field. The weight of extra switches would offset the weight savings of removing a battery. Furthermore, this speaker will go all day on a charge. I turned it on the other day, and fell asleep when it had been on for over 15 hours connected to my portable music player. So, I don't really know how long it went before the low battery protection circuit turned it off. I just know it lasted longer than I did without sleep. The battery recharges quickly, so you wouldn't have to wait long to go another day using it nonstop, if you didn't charge it while you slept.

My KXFL3 has 10 pins not 12 as in the original version and not 9 as in the tuning noise mod. Was this an interim configuration? Did the noise mod only cut two pins initially? It seems to work properly, now anyway see below. Should I now remove the tenth pin or does it matter? I carefully followed the most recent calibration instructions using the ?sniffer? loop. I was initially able to obtain a null only on FL1. The gain and phase adjustments did nothing at all using FL2 or FL3. I assumed that I might have a faulty filter or that the 10 interface pin configuration was causing a problem. After several attempts, each carefully following the directions, I spun the tuning knob rapidly several rotations while attempting to null FL3. The system then worked perfectly and I was able to get a deep null. I then went to FL2, without repowering the rig or changing any settings but those as described in the procedure and neither the gain or phase had any effect just as before. Also just as before several rapid rotations of the VFO knob resulted in normal behaviour and the ability to obtain a deep null. I can now switch between filters and set each of them immediately just as the procedure describes. I am pleased that the calibration was a success but remain quite curious as to the cause of this strange behavior. Does anyone have any ideas?

In my original post I stated that after sending the M>V macro (which does bring up the flashing memory number) that pressing the Up or DN macro caused the display to revert to its original frequency and nothing else happens.. That's not quite right. Subsequent sends of the UP or Dn macros cause VFO A to increment or decrement. But sending either the Up or Dn from the K-pod kicks the K3 out of memory mode. Everything works perfectly from the utility, so it seems to be a K-pod issue.

V- is NOT GROUND, it is the return for DC power. Bonding V- to ground is a BAD idea -- that's why virtually all pro-grade power supplies are built either without the bond or so that the bond can easily be removed."

Just my 2-cents, but both statements are correct, depending on the context. Let's compare figures 3 & 4 in K9YC's link: http://k9yc.com/PowerSupplyBondingAndAudioDistortion.pdf The transceiver's return lead current is controlled in figure 4, but only if 12V accessories are not connected to the power supply. The moment we do, we essentially create the condition shown in figure 3 -- and to K2VCO's point, the supply's V(-) lead and chassis will come together by virtue of the accessory equipment and the ground lead of the supply's AC power cord. Complete control of the transceiver's return current is then lost and we must rely on much heavier gauge wire to ensure the return lead current does not split into accessory equipment. I now run one transceiver to one 12V PS. One rig, one supply. Accessories are connected to a separate supply and feed a RigRunner DC power manifold. Accessory current through the RigRunner is low and no external audio gear is powered from it.

It is really two questions. The operational range of the K3 as one. The second is really the optimum range of the K3. In dealing with the drops between the K3 and power supply how much is excessive? My Astron is set for 14 volt and drops at the K3 under XMIT. How much drop would be necessary for the IMD to rise to an unacceptable level? Or put another way what is a reasonable goal for the drop in the power cable or power distribution to the K3? Zero millivolts would be ideal but not obtainable. I'll admit to not having the knowledge or test gear to measure the IMD. If instead of getting 100 watts I could only get 95 watts to me that would be insignificant. But I don't want to XMIT a "dirty" signal either. 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 4/17/2018 7:55 PM, john at kk9a.com wrote: > I believe that the transceiver will operate below 11 volts but it is better > to keep it in the higher part of the voltage range.

SS30 is an SMPS so a different beast than the prior discussed linear supplies. It's possible that the DC return to chassis connection is needed for EMC compliance. That's providing a low impedance return path for noise generated by switch elements. Without the connection, noise will take an unwanted path and come out as common mode noise. A frequent source of the noise is capacitive coupling from MOSFETs to chassis, sometimes via a heat sink. I would be hesitant to simply insulate the DC neg from chassis. One possibility would be to cut the copper around PCB mounting screws (carefully!), and put a cap between them so you maintain an AC connection but block the unwanted DC path. You want the capacitor value to be much greater than the parasitic capacitance. 73, Josh W6XU On 4/18/2018 11:10 AM, Michael Blake wrote: > I though I would separate this from the other discussion. It seems that my newest Astron SS30 power supply does not allow for the negative post to be isolated from the chassis. The green wire can be disconnected from the chassis but the negative rail of the DC output can not be isolated from the chassis. The negative rail is firmly connected to the chassis via two of the circuit board mounting screws. Separation would only be possible by using insulating washers and nylon screws. > > This is not true in one of my older supplies.

When V- is NOT bonded to shack ground, the power cable forms a transmission line, confining the field for noise current to a small region around the pair. But when V- IS bonded to shack ground, return current divides between the shack ground path and the V- (black) conductor. The fields no longer cancel, the noise current takes whatever path it chooses, and a magnetic loop is formed between? V+ and shack ground. Common mode noise current can easily be blocked using ferrite chokes on the DC cable just was we do with coax. > A frequent source of the noise is capacitive coupling from MOSFETs to > chassis, sometimes via a heat sink. Yes. Interior circuit design and layout is critical to low RF noise. 73, Jim K9YC From alaparos at w2cs.net Wed Apr 18 18:17:10 2018 From: alaparos at w2cs.net (alaparos at w2cs.net) Date: Wed, 18 Apr 2018 18:17:10 -0400 Subject: [Elecraft] KPA1500 Caution Message-ID: <393E0158-B196-4B80-BF05-0CE9ADE93B9E@w2cs.net> I?m a day-2 KPA1500 patient waiter.

I have been shipping and receiving many packages since 2004. I have only had one damaged that I have shipped, and that one was impaled by some sharp pointed object. Of the ones I have received, a few have had minor case damage - a result of inadequate packaging. If the package is packed so the equipment cannot shift in the box, it will not be damaged except in the event of a catastrophe. 2 inches of packing material on each side is adequate, but those newer large air bags are only adequate for packing lightweight items - they will burst with the weight on a radio.

None of the carriers treat your package with kid gloves, and a lot of it is automated such that they really don't pay any attention to "Fragile" notices, etc.? Most of the time if your package is damaged before your local delivery person gets their hands on it, it is due to low quality packing materials used by the shipper. Judging the overall nationwide quality of the USPS, UPS or Fedex based on what you see from your local delivery people doesn't make much sense.? That's why when people get in this type of discussion you hear about all the nightmares of a particular service from one person, and all the kudo's of the same service from another person. I happen to be lucky in that my local delivery people for all three services vary from very good to outstanding (my USPS carrier, when delivering a package, comes to the door with the rest of my mail, and rings the bell, waiting for me to come to the door. If I'm not home he places the package behind a post near the front door, and delivers the mail to the street mailbox). But friends living in the same town with postal workers working out of the same post office facility, have lots of bad experience with their carriers, and therefore hold a very prejudicial view of the USPS. Now there are other services that are terrible, and the problems occur throughout the system.? Amazon Prime occasionally uses a service called Ontrac, which ships to 8 states in the west. At least here in Colorado, they are reprehensible, and border on fraud when it comes to making their shipping comitments. Based on online reviews, I don't think they're any better anywhere else. 73, John AC0ZG From jim at audiosystemsgroup.com Thu Apr 19 01:41:45 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 18 Apr 2018 22:41:45 -0700 Subject: [Elecraft] Packing Peanuts Are Of the Devil!

I have a 200 foot long driveway, the end of which is out of sight of my front door. UPS often dumps packages at the end of the drive, in full view of the road, and out of sight of the house even if I'm home! The drivers simply don't want to pull into the narrow drive (and back out) and they're too lazy to carry the package to the door (or put it on a dolly if it's more than 25#) and wheel it up the (concrete) drive. 73, ...

I know that anything shipped to me over $1,000 or sometimes even $500 will require my signature. I get around the having to be home issue by having the package shipped to the local UPS store. Yes, it costs $5.00, but well worth the convenience. There are two ways to have your package delivered to the UPS store after being shipped to your home address: One, leave a note on the door where the delivery man left his note yesterday telling him to drop it off at the UPS store. The second way is using the tracking number go to the UPS website and change the delivery address to the local UPS store. I've done number two many times when the UPS delivery man and I have had trouble connecting at my home. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of N4ZR Sent: Thursday, April 19, 2018 11:52 AM To: Elecraft List Subject: [Elecraft] UPS Practice? was:Re: KPA1500 Caution I have had good luck with USPS, but am less than thrilled with UPS.

The house cannot be seen until you get halfway up the driveway. UPS delivers to my front door and USPS does the same for packages that will not fit in the mailbox. I am signed up for UPS My Choice, so I am notified when a package will arrive. I also signed the Driver Release so the driver can leave a package even though it is insured and I am temporarily away. I am very careful to set a "vacation stop" for both UPS and USPS when I will be away for an extended period of time. That guarantees that the driver will not leave a package when I am away from home for an extended period. Delivery service from both carriers is excellent here, but as has been said, much depends on the local delivery person. I reward mine with a gift during the holiday season, and it pays benefits. USPS and UPS both work well for me. I do not have the same flexibilty with FedEx, but that is not to say they are not a good carrier. 73, Don W3FPR On 4/19/2018 9:18 AM, Joe Subich, W4TV wrote: > On 2018-04-19 9:00 AM, Dave Sublette wrote: > > > > I know it is disappointing to miss a delivery, but the other fellow is > > right.?

I try to keep up with everyone's inquiries. The original response is at the bottom: Hi Mark, Thanks for your feedback. I've been wondering the same thing about the grille. A square or rectangular grille would mimic the look of the Elecraft SP3, which is a plus. On the other hand, in order to have a volume knob on the face, a square or rectangular grille would likely force the enclosure to be wider to accommodate both the grille and knob. The round grille allows a knob to be placed in the corner with ease. Also, a round grille weighs less. I used a round grille for the first prototype because I was able to source one that fit the speaker driver I'm using. So, I could at least have a complete speaker. Fortunately, it looks better than I had anticipated. Of course, your question is, which would look better? For many, it comes down to personal preference. I'm open to what you and others prefer. Thanks and 73, Robert (AG6ZZ) ------------------------- Robert, I love the idea, I'm wondering about whether a square or rectangular speaker grill would look better. 73, Mark KM6HFR From kl7uw at acsalaska.net Thu Apr 19 15:40:39 2018 From: kl7uw at acsalaska.net (Edward R Cole) Date: Thu, 19 Apr 2018 11:40:39 -0800 Subject: [Elecraft] OT: shipper from H Message-ID: <201804191940.w3JJegjX001955@mail41c28.carrierzone.com> hopefully topic will pass political correction police.

One incident involving Styrofoam peanuts comes to mind. We were called into a California border inspection station for what was supposed to be a routine inspection. The lady on duty ordered me to open the doors of the truck's trailer so she could see that we were hauling what the waybill said. I told her that the trailer was loaded with bulk blown-in Styrofoam peanuts and she really didn't want me to do that. Her response was to -order- me to open the doors.

It also lets you see photos of mail pieces (non-packages) heading your way. Fedex has something similar as well. One thing that's great about these services is they tell you what's coming to your address even if you don't have a tracking number. It's definitely worth signing up for these free accounts. You also get the ability to prepay for shipping and print labels. That saves time at the P.O. and sometimes I can get UPS or Fedex to pick up the package for fee when they're delivering one. I agree that any one of these services can and will damage goods that are not packed well. That's on the shipper. Most of the horror stories I've heard were due to the shipper not packing the goods adequately (though sometimes that can be undone on an international shipment by customs inspectors.) That said, I've seen some instances where the box itself was penetrated or crushed, which is on the carrier. I believe custom foam inserts and double-boxing are the best way to protect electronic equipment, though double boxing almost always involves the dreaded peanuts. I live at the end of an 1100' gravel driveway, so the carriers can leave packages on the front porch with little or no danger that they'll be stolen. Even so, for something as expensive as a KPA1500 I would opt for a signature being required. I suspect that if you don't do that you could have trouble collecting the full insurance. Also, several times UPS has delivered our packages to the wrong address. We were able to get them back, but that might not be the case with something really expensive. Sometimes a substitute driver will refuse to venture down our driveway for fear of not being able to turn around (the turn-around isn't visible from the road) or fear of getting stuck in snow, ice or mud. So they leave the package in the mailbox (which I believe is illegal) or they put it in a plastic bag tied to the mailbox post. The mailbox is right on the highway in front of our driveway, so the package could be stolen easily. A couple of times they just dumped the box in the snow at head of the driveway. I usually call to let UPS know so they can tell the drivers not to do that. Again, requiring a signature gets around that problem but also requires that we hang around all day. I recently had a signature-required shipment where the estimated delivery times were off by many hours so I missed it twice and had to pick it up at the UPS depot 20 minutes away. My least favorite delivery method is SurePost. UPS picks up the package, sends it to your region, then hands it off to USPS for the last part of the trip. That always adds at least one day, if not several days. All this said, it amazes me how much stuff we're buying online these days and how cheap the shipping has become. 73, Dick WC1M -----Original Message----- From: john at kk9a.com Sent: Thursday, April 19, 2018 12:37 PM To: elecraft at mailman.qth.net Subject: [Elecraft] UPS Practice? was:Re: KPA1500 Caution Sign up for UPS My Choice https://www.ups.com/mobile/deliveryplanner?loc=en_US and you will be aware of every package coming to your residence.

I didn't really have a problem with it, but I bought it used in 2005, had W3FPR look at it then, and install latest mods to bring it up to date. Today, I thought it might be time to take a look at alignment, and freshen it up a bit. When I did the "PLL Ref Osc Range Test" in Alignment Part II, the range was slightly less than 6 kHz. When I got to "VFO Linearization", 40 meters was fine without any INFO messages. I was using the original Rev B manual (not related to RevB board) that came with it. Under Part III, Alignment and Test there is another "VFO Linearization (All Bands)". I did that and every band failed (INFO 232) except 40 meters. And of course, in the Rev B manual, there is no INFO 232 only 235. Anyway, I checked around Q19 as the Troubleshooting suggested and found X1, but no X2. After reading the circuit operation, I was convinced somehow X2 got left out. Since it was supposed to be there to prevent the very short range problem I thought I was experiencing, I thought I had found the problem. I emailed Elecraft to order X2, and got a nice note from Mike saying they would send one out no charge. That kind of service still amazes me. But I told him to hold off until I can hear from this group. I checked my other K2 manual (I also have SN 6911), and, first, it does not have a procedure for VFO linearization on anything but 40 meters. In fact, it says INFO 232 probably occurred because I wasn't on 40m. And the parts lists says X2 is not used! I went into this without having any actual problem or complaint. The old manual convinced me I did. The later Rev I manual says I might, but didn't know it. I'm supposed to have a PLL range of 9.8 to 15 kHz. I have 5.97 kHz. So if that is a problem, the problem is associated with Q19 which is a very simple stage. X1 is probably the most likely cause. Any ideas? Also, since two crystals were originally used to "de-Q one another to increase the tuning range", what was done to make two crystals unnecessary?

It is the firmware level, not the upgrades or the board level. Firmware 2.01 and above must do CAL PLL on 40 meters.? That calibrates it for all bands. The early manuals tell you to do CAL PLL on each band, but if the firmware has been updated, the instructions for the updated firmware can supersede the earlier instructions in the manual. 73, Don W3FPR On 4/20/2018 8:27 AM, hawley, charles j jr wrote: > So A to B upgrades but not necessarily the rev B board? > > Chuck Jack > KE9UW > > Sent from my iPhone, cjack > >> On Apr 19, 2018, at 11:32 PM, Don Wilhelm wrote: >> >> Erik, >> >> Your K2 has the A to B updates, do NOT put X2 in! >> For Firmware level 2.01 and above, CAL PLL is done only on 40 meters (for all bands).

On my amp it occurs when the transistors heat up. Keeping the fan on a higher speed will eliminate this clicking however then you have to listen to fan noise. Perhaps Elecraft has a fix for this but I have not used the amp enough to pursue it. John KK9A Craig Buck k4ia wrote: Make sure the transformer is on straight and secured.

(1/2 carrier for SSB). But now I am setting up a 600w linear amp to run at P1 which is about 0.9 of P3 (saturated power) and wondering what level of carrier power to run in SSB to stay linear and also not to overdrive and stress the expensive LDMOS device in the amplifier. I'm running the K3 in transverter mode on 28-MHz so max output is 1.5mw. I can view this with a scope. The amplifier is running at 1296-MHz which is too high a freq to monitor with my scope. I can only observe average RF power from a directional coupler and diode detector (like a Bird meter). Normally, I just set power on the K3 to drive my amp to nominal full power and select SSB mode. Modulation level is set by observing ALC meter. I is ALC showing five bars when saying the word "five" loudly and six bars with compression. So does this mean the K3 automatically adjusts RF power in SSB to stay linear with proper modulation audio setting? My reason is when running 1296 SSB to avoid overdriving the amplifier into P3 possibly causing harm, as much as not wanting to produce non-linear products. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From donwilh at embarqmail.com Mon Apr 23 06:52:06 2018 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 23 Apr 2018 06:52:06 -0400 Subject: [Elecraft] K3: Adjusting SSB modulation for proper PEP rating In-Reply-To: <201804230856.w3N8upZk023791@mail47c28.carrierzone.com> References: <201804230856.w3N8upZk023791@mail47c28.carrierzone.com> Message-ID: <5b0cc89b-5160-4c12-ce63-0e3ae465cb3e@embarqmail.com> Ed, The power you request with the power knob is the PEP level that the K3 will control.

Of course in CW PEP=carrier power and makes sense. I never really *asked* this question before as I always had nice reports on my SSB. Gives me confidence running my new *expensive* LDMOS kilowatt amps on 144 and 1296 plus my old-school 16 NLA transistor Harris on 50-MHz when running SSB. Mostly run them "full bore" with either CW or digital on eme, where PEP is approx equal to carrier power. The 144 and 1296 amps are new and not yet QRV (but soon). I will sell my 2m W6PO-8877 with HVPS when this is accomplished. Passing of an era to "no-tube" operation which started 60 years ago with a DX-35 (6146). 73, Ed - KL7UW At 02:52 AM 4/23/2018, Don Wilhelm wrote: >Ed, > >The power you request with the power knob is the >PEP level that the K3 will control.

Borrow the receiver if necessary. You can't tell much by the KX3 monitor. Connect the dummy load to the ANT jack and connect a short wire to the other receiver. Place that wire far enough away from the dummy load to obtain about an S-9 signal. Listen with headphones. Transmit at several power levels. How does the signal sound at each. If it sounds OK on the dummy load, then look for RF in the shack to be the problem.

I finally narrowed it down to the fact that I had it connected to my computer (RS-232 for sure and I might have been feeding the receive audio into the computer sound card as well).?? I made a K3 chassis to computer chassis bonding strap using some RG-8 braided shield.? I started out with the strap being about three feet long and kept shortening it until the distortion totally went away at about 12 inches long (verified using a second battery powered rig to listen to my own signal). So the first thing I would do is make sure all of your gear adheres to proper bonding practice. 73, Dave??

If so, connect the dummy load to the KXPA100 and put a short antenna wire on the other receiver. Transmit, and adjust the distance between the dummy load and the other receiver "antenna" to produce an S-9 signal. Does the KXPA100 produce a distorted signal? If not, then look carefully at your antenna system - the likely problem is RF-in-the-shack. OTOH, if the KXPA100 output is distorted working into the dummy load, you should contact support at elecarft.com with those facts. One thing that can cause some distortion is low power supply voltage to the KXPA100. That voltage should be at least 13.8 volts during receive and drop to no less than 13.2 during transmit at 100 watts. Low voltage during transmit can cause increase IMD (distortion). 73, Don W3FPR On 4/23/2018 11:32 AM, Ray W2RS via Elecraft wrote: > > My KXPA100 transmits distorted audio on SSB, but works normally on CW and RTTY.

I only use CW Once I have spotted a weak signal I can use these to narrow down and filter out unwanted noise on the chosen signal I can also apply the APF filter and tune that way. Recent advice suggested that the APF function works best when when used with a DSP/crystal filter WIDTH setting of 300-500 Hz Does this mean I switch on the Notch and tune to this range on the notch setting and how does this work with the bandwidth settings on the PBT function? Do I leave the notch on whilst tuning for other signals or only use it when I have a weak signal in the first place.

The notch filter is only used to notch out an *unwanted* signal - use it carefully since you can easily notch out the signal that you are trying to receive. First use the DSP filter to home in on the wanted signal - the PBT knob. The roofing filter will follow along with the width of the DSP passband. Once you get the wanted signal, you can optionally use APF if it is of benefit. If there is an unwanted signal within the passband, you can use NOTCH to reduce it. 73, Don W3FPR On 4/24/2018 6:03 AM, john daws wrote: > (not sure if this is the same as using the KX3 users group but here goes) > > Would appreciate advice on the use of the* notch filter* on my KX3 > > It is fitted with* KX3FL3* roofing filters.

In the time I've had the radio, I've used it exclusively for FT8. The first thing I did was to set it up for digital modes using settings from a YouTube video by K5ACL. Specifically: AGC MD: off (default is on) Mike bias: off (default is on) RS232: Set to desired baud rate. KX3 supports max 38400 baud RX EQ: off TX EQ: off TX GAIN: ALC 25 (this is the default) Mode: USB This all worked fine. Not long thereafter II changed from setting the KX3 mode to USB, and have been using the Data mode instead. Now I'm looking at expanding use of the radio to CW and perhaps to voice. I therefore wanted to revisit the settings to make sure I understand them all, and know which are important. Some questions: 1) Do all of the above seem important for digital modes such as FT8? I believe I read somewhere that when the KX3 is put into Data mode it will make some of these changes anyway. Are there any I don't need to worry about as long as I select Data mode for FT8 and other digital sessions? 2) Should I change any of the above settings for CW? 3) Should I change any of the above settings for phone? Wondering for example about the mike bias and EQ.

If that video suggests using USB and disabling EQ, I wouldn?t trust it, because it is giving wrong advice. Use the "DATA A and AFSK A (Audio Data Modes)" instructions in the KX3 manual instead (page 18). Also, I?m not sure I see the benefit of turning AGC off for digital modes.

But definitely use DATA A, not USB. Reason is that Compression and EQ is automatically set to zero, and your SSB settings can remain undisturbed. You mic gain setting is the most important when using data modes. Set it so you have 4 bars solid on the ALC meter with the 5th bar flashing. You may want to read the article dealing with setting the audio gains (yes, there can be up to 3) that is on my website www.w3fpr.com. Scroll the left column down to the bottom and click on the link to the article. There is no sense in setting RS232 to a slower baud rate unless the application software demands it. For voice and CW modes, you want to have AGC on. TX and RX EQ can be set to whatever your ears like. 73, Don W3FPR On 4/24/2018 4:02 PM, Frank O'Donnell wrote: > Hi all, new ham here and a KX3 owner for three weeks.

My antenna is a Hy-Gain AV620 elevated vertical, fed with 100 feet of Davis Buryflex (direct bury, feedline loss comparable to Belden 9213). SWR is 1.5 or lower on 20 through 6 meters. Don makes an interesting point about power supply voltage. As I mentioned, it is 13.7 on receive and 13.1 with 100 watts output. That is on 20 meters. On 10 meters, it is 12.7 with 100 watts output. By Don's figures, that is a possible problem. I've got lots of receivers. I tried listening to myself on a KWM-2, chosen because it's got vacuum tubes. There is distortion at all power levels with the KXPA100, but no distortion with the barefoot KX3. That argues against supply voltage being the sole cause, but there could be more than one. I want to try one more thing: the Elecraft mike. I've had RF problems with several other mikes and rigs, and I want to try a mike that I know is clean. Unfortunately it has an 8-pin Yaesu cable, so I've ordered an adapter that plugs into the KX3. When it comes, I'll post the results. 73 Ray W2RS To subscribe or unsubscribe via the World Wide Web, visit http://mailman.qth.net/mailman/listinfo/elecraft or, via email, send a message with subject or body 'help' to elecraft-request at mailman.qth.net You can reach the person managing the list at elecraft-owner at mailman.qth.net When replying, please edit your Subject line so it is more specific than "Re: Contents of Elecraft digest..."hee being Today's Topics: 1.

(1/2 carrier for SSB). But now I am setting up a 600w linear amp to run at P1 which is about 0.9 of P3 (saturated power) and wondering what level of carrier power to run in SSB to stay linear and also not to overdrive and stress the expensive LDMOS device in the amplifier. I'm running the K3 in transverter mode on 28-MHz so max output is 1.5mw. I can view this with a scope. The amplifier is running at 1296-MHz which is too high a freq to monitor with my scope. I can only observe average RF power from a directional coupler and diode detector (like a Bird meter). Normally, I just set power on the K3 to drive my amp to nominal full power and select SSB mode. Modulation level is set by observing ALC meter. I is ALC showing five bars when saying the word "five" loudly and six bars with compression. So does this mean the K3 automatically adjusts RF power in SSB to stay linear with proper modulation audio setting? My reason is when running 1296 SSB to avoid overdriving the amplifier into P3 possibly causing harm, as much as not wanting to produce non-linear products. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com ------------------------------ Message: 2 Date: Mon, 23 Apr 2018 06:52:06 -0400 From: Don Wilhelm To: Edward R Cole , Elecraft Reflector Subject: Re: [Elecraft] K3: Adjusting SSB modulation for proper PEP rating Message-ID: <5b0cc89b-5160-4c12-ce63-0e3ae465cb3e at embarqmail.com> Content-Type: text/plain; charset=utf-8; format=flowed Ed, The power you request with the power knob is the PEP level that the K3 will control.

Of course in CW PEP=carrier power and makes sense. I never really *asked* this question before as I always had nice reports on my SSB. Gives me confidence running my new *expensive* LDMOS kilowatt amps on 144 and 1296 plus my old-school 16 NLA transistor Harris on 50-MHz when running SSB. Mostly run them "full bore" with either CW or digital on eme, where PEP is approx equal to carrier power. The 144 and 1296 amps are new and not yet QRV (but soon). I will sell my 2m W6PO-8877 with HVPS when this is accomplished.

Borrow the receiver if necessary. You can't tell much by the KX3 monitor. Connect the dummy load to the ANT jack and connect a short wire to the other receiver. Place that wire far enough away from the dummy load to obtain about an S-9 signal. Listen with headphones. Transmit at several power levels. How does the signal sound at each. If it sounds OK on the dummy load, then look for RF in the shack to be the problem. OTOH, if it sounds distorted into the dummy load, contact elecraft support - support at elecrat.com 73, Don W3FPR On 4/23/2018 12:14 PM, Ray W2RS via Elecraft wrote: > Hi Kurt, > > > It's hard to tell because the monitor plays the KX3 audio, which is good. > > > Tnx, Ray > > > > > -----Original Message----- > From: Kurt Cramer > To: rsoifer1 > Cc: elecraft > Sent: Mon, Apr 23, 2018 8:58 am > Subject: Re: [Elecraft] KXPA100 SSB Distortion > > Does it work correctly into a dummy load.

I finally narrowed it down to the fact that I had it connected to my computer (RS-232 for sure and I might have been feeding the receive audio into the computer sound card as well).?? I made a K3 chassis to computer chassis bonding strap using some RG-8 braided shield.? I started out with the strap being about three feet long and kept shortening it until the distortion totally went away at about 12 inches long (verified using a second battery powered rig to listen to my own signal). So the first thing I would do is make sure all of your gear adheres to proper bonding practice. 73, Dave??

If so, connect the dummy load to the KXPA100 and put a short antenna wire on the other receiver. Transmit, and adjust the distance between the dummy load and the other receiver "antenna" to produce an S-9 signal. Does the KXPA100 produce a distorted signal? If not, then look carefully at your antenna system - the likely problem is RF-in-the-shack. OTOH, if the KXPA100 output is distorted working into the dummy load, you should contact support at elecarft.com with those facts. One thing that can cause some distortion is low power supply voltage to the KXPA100. That voltage should be at least 13.8 volts during receive and drop to no less than 13.2 during transmit at 100 watts. Low voltage during transmit can cause increase IMD (distortion). 73, Don W3FPR On 4/23/2018 11:32 AM, Ray W2RS via Elecraft wrote: > > My KXPA100 transmits distorted audio on SSB, but works normally on CW and RTTY.

The notch filter is only used to notch out an *unwanted* signal - use it carefully since you can easily notch out the signal that you are trying to receive. First use the DSP filter to home in on the wanted signal - the PBT knob. The roofing filter will follow along with the width of the DSP passband. Once you get the wanted signal, you can optionally use APF if it is of benefit. If there is an unwanted signal within the passband, you can use NOTCH to reduce it. 73, Don W3FPR On 4/24/2018 6:03 AM, john daws wrote: > (not sure if this is the same as using the KX3 users group but here goes) > > Would appreciate advice on the use of the* notch filter* on my KX3 > > It is fitted with* KX3FL3* roofing filters.

After 'training' the tuner, do you switch the tuner to MANual? If not you should. If left in AUTO, there will be times when the tuner will try to tune even though it had already been tuned on that band segment. That behavior is due to the fact that the forward and reverse power cannot be measured at exactly the same time. On SSB for instance, if the forward power is sensed at a time when the audio is low, and then the audio increases when the reverse power is measured. the SWR calculation will say (incorrectly) there is a high SWR and the tuner will attempt to tune. Leaving the KAT500 in MAN mode prevents that behavior. Remember that an SWR of 1 is not essential. An SWR of 1.2 or 1.3 is quite acceptable and will keep the KPA500 quite "happy". 73, Don W3FPR On 4/24/2018 3:55 PM, Brian D wrote: > Are the segments on fixed frequencies?

I didn't mention it in my prior post, but setting the mike gain to achieve ~4.5 bars on the ALC meter is indeed something I paid a lot of attention to. On that general topic, I've heard others talk about a couple of strategies for making sure that you're getting a clean digital signal out that isn't overmodulated. One is to have a local friend take a look at your signal as received at their location. Another apparently is to run your transceiver into a dummy load, then use an SDR or similar receiver close by with a hank of wire as an antenna to sample the signal you're putting out. I can't remember, however, if those discussions were in the context of Elecraft radios. Does it seem reasonable to run my KX3 into a dummy load (perhaps with the power out turned down) and listen to it with, say, an SDRplay to evaluate the signal out? Keeping the levels low of course to protect the SDR. One other point about the audio setup for digital. When I was getting my gear configured, I tried using a couple of different soundcard devices. One of them seemed to work fine with both right and left stereo channels plugged in between the soundcard and KX3. When I tried the other soundcard, however, I got a PTT error when powering up the KX3. After I unplugged the stereo channel on that soundcard that went to the ring connector on the KX3 mike in, everything worked fine. Is that a problem known to occur with some soundcards?

The 1st 4 bars of the KX3 ALC meter are not showing ALC at all. ALC activation does not start until the 5th bar. Yes, you can operate into a dummy and listen with another receiver - it does not have to be an SDR receiver, most any will do. I have not heard of a soundcard which would apply an effective ground on the right channel (PTT). 73, Don W3FPR On 4/24/2018 8:48 PM, Frank O'Donnell wrote: > Don, thanks for the comments.

It is actually two filters, one for ?I? and the other for ?Q? (the quadrature signal paths). Each filter has two LPFs, one for CW, the other for SSB and data. To keep the phase and amplitude balanced, we use capacitors that are hand-trimmed to 0.25% tolerance. The result is an effective roofing filter for the ADCs and DSP. If the KXFL3 is not installed, the radio uses an 8 kHz IF, like the KX2. 73, Wayne N6KR > On Apr 24, 2018, at 11:23 PM, Petr, OK1RP/M0SIS wrote: > > John, > > just to know, there are no xtal filters in KX3.

You might consider flat copper tape instead of wire for bonding. Lightning is an RF event and currents will be confined to the outside surfaces of the conductors.? Consequently, the surface area rather than volume of the conductor is what matters most. The conductors on one of the original transmission lines from Hoover Dam to Los Angeles were hollow. As to your last question, "it depends."? There's no predicting what a direct strike on your tower might do, the currents are so high that everything in whatever path it chooses becomes a conductive plasma.? And, just because your tower is there does not mean all the strikes will be direct.? The W7RN contest station is on an exposed ridge at 6,500 ft with multiple towers.? As Tom points out, the lightning seems to choose a sagebrush bush randomly more often than one of the towers. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 4/25/2018 9:41 AM, Terry Brown wrote: > I am building a new house.

Yes, the RANE HC-6 would work. And they make several other small mixers that make it easy to switch and route audio.? While the mixers may not have a stereo headphone output, you could easily make a cable adapter from the outputs to a cable-mounted stereo jack. I would study their catalog and look for the products used on ebay. There's also a discontinued Shure product that does what you want. It's the model FP22 headphone amplifier.

If grounds from both radios bonded together it should be fine, depending on extent of "pin 1" problem internal to radio. Two SPDT toggle switches would accomplish this. One switch for each ear which selects between the two radios. That's assuming you only care about mono sources. If you need isolation transformers use 1:1 or close to that.

In such a case, a circular cross-section conductor will present less impedance. The vast majority of the energy in a lightning strike is well below 1 MHz and at 125 Hz the 100 effective skin depth is nearly a half inch. As a practical example, following the R56 industry standard for grounding and lightning protection for radio towers and their equipment shelters, you will find a round, usually 2-gauge ground "halo" circling the walls at a short distance from the ceiling. Strap is NOT used. On the other hand, grounding at HF frequencies, where several skin depths can be easily achieved with copper strap (0.005 inch at about 1 MHz) then thin flat strap or hollow tubing is the way to go. - Jef N5JEF On Wed, Apr 25, 2018 at 12:27 PM, hawley, charles j jr < c-hawley at illinois.edu> wrote: > I gave the reference. 4th edition of Terman, Electronic and Radio > Engineering.

Flat conductors have much higher RF resistance in free space compared to circular conductors of similar size. Big changes happen when the environment is no longer in free space, such as those described in this excellent EE Times article that describes the RF resistance of flat conductors used in transmission lines and RF transformers: https://www.eetimes.com/document.asp?doc_id=1278215 73 Frank W3LPL ----- Original Message ----- From: "GWK" To: elecraft at mailman.qth.net Sent: Wednesday, April 25, 2018 10:40:20 PM Subject: Re: [Elecraft] OT: Grounding Question Does this imply that, for RF, the width of the strap is of minimal importance, and that a 1/4 inch strap is almost as effective as a 1" strap?

The chapter on skin effect. The rf current is pushed to the outside edge of any conductor because the rf current is distributed in such a way as to make most of it flow where it is encircled by the smallest number of flux lines. And that?s the outside edge of any conductor. The rf current in the center obviously would be encircled the most. Terman gives a very clear description if you can source his text. He states that it is not the amount of conductor surface, but rather the way in which the conductor material is arranged. And I do realize that this is a very misunderstood subject. I?m not saying that flat ribbon doesn?t have skin effect, but just where the rf flows. Much of the outside surface in the middle of the ribbon has a high resistance to rf. So if you are using a ribbon of wire, it would have to be much larger than a round wire to have any advantage. > I have the Radio Engineers Handbook also and it does not have the same chapter on skin effect. > > Chuck KE9UW > c-hawley at illinois.edu > > Sent from my iPad > >> On Apr 25, 2018, at 1:34 PM, Josh wrote: >> >> You're going to have to explain that to a whole lot of high current flat wound inductors & transformers. >> >> What are you referencing?

Scanning a seemingly ?dead? band segment can reveal signals as they come up, allowing you to do other things (work out, paint, dust, reread ?Ecotopia? by Ernest Callenbach, brew an IPA, whatever). You might think of scanning as an eyes-free panadapter. Well, I do. The basic scanning mode keeps the receiver muted until signals appear. It?s a real ear-saver. In addition, the K2, K3/K3S, and KX3 have a ?live scan? feature that simply scans continuously with the receiver audio unmuted. This is especially useful on bands where very weak signals might appear from nowhere out of low-level atmospheric noise, say 15 meters. All of these radios also support hopping among a set of labeled memories. This is typically used on 60 meters or other channelized bands, e.g. those with repeater allocations. For details, see ?Scanning? in your owner?s manual's table of contents. Tips: - If you?re scanning for CW signals, perhaps this coming Friday in honor of Morse?s birthday (hint), set the bandwidth very narrow (50-200 Hz). - If there?s a lot of band noise, turn off the preamp. This will give the scanning algorithm more audio dynamic range to work with. - Scanning steps match those set up for the VFO knob; using fine steps will miss fewer signals but take longer to scan the segment of interest. - Configure all of the above *before* saving setups to memory as scan start/stop end points (VFO A and B). Later, you can recall your favorite scan ranges preconfigured for various band conditions. 73, Wayne N6KR From k6dgw at foothill.net Thu Apr 26 00:49:25 2018 From: k6dgw at foothill.net (Fred Jensen) Date: Wed, 25 Apr 2018 21:49:25 -0700 Subject: [Elecraft] Samuel Morse's birthday (Friday, April 27th); good excuse to break out your old hand keys In-Reply-To: <48F17A07-A981-4CED-A8C2-4131BDB53194@elecraft.com> References: <48F17A07-A981-4CED-A8C2-4131BDB53194@elecraft.com> Message-ID: So where and when might we find you??

For now I am using the KEY OUT connector for the keying of the HF PA. How can I get a key out signal for my coming VHF PA? To the best of my knowledge the two amplifiers have different voltages on the connection. So I believe I cannot just use an Y-splitter. I see on page 19 in the manual for K3: For transverter keying, you can use KEYOUT-LP signal (pin 10 of the ACC connector) or the KEY OUT jack (RCA). But how about the potential and other details on this connector? To the best of my knowledge my coming VHF PA has 5V on the center pin of its key in connector.

I had K3 s/n 3505 and it still had the tin pins not the gold ones. When I sent it in for updates before selling it to my brother-in-law they replaced the pins. I had never had any trouble with it. It seems it is standard procedure when an early K3 arrives for updates the tin pins are replaced with gold pins. You can get the gold pins from Elecraft and replace them yourself. Sometimes, just removing the front panel and replacing it wipes the pins enough to eliminate erratic problems. One of the Elecraft techs told me that production with the gold pins started in the s/n range 4000 to 4100. I can't confirm that, but I would take the tech's word for it. Don, W3FPR may be able to verify some of this. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Steve Sent: Friday, April 27, 2018 1:03 AM To: Elecraft at mailman.qth.net Subject: [Elecraft] Odd problem I have K3 s/n 3400 plus which I?ve owned since.

I can now change the 'RX ANT' by using the AR1 & AR0 commands. When I ran the K3 Utility earlier, and checked for the latest K3 release firmware release, it indicated that 5.57 was the most current version and that is what I had been using in my K3. However, on the 'K3/K3S Software' page it indicated that the latest current revision was 5.62 dated Nov 16, 2017 and not 5.57 that was indicated when I checked with the K3 Utility. Apparently the older 5.57 version which I was using did not have the capability of using AR0 and AR1 commands to control the "RX ANT". With the command working now, I can now remotely switch the K3 receiver between the main and Beverage antennas with my Android smart phone using the . Thanks for your rapid and right on the mark solution to my question. My almost decade old K3 is performing great. Since its introduction back last summer, I've been playing with the new WSJT-X FT8 digital mode. I've been working many grid squares, but my primary focus has been chasing DX. Using the K3, running 75 Watts with an A3S yagi and wire antennas, the K1HTV FT8 DXCC country totals presently stand at 214 worked and 201 confirmed. Thanks to Elecraft for producing such a great, high performance radio. 73, Rich - K1HTVhttp://www.qrz.com/db/K1HTV = = = > On April 26, 2018 at 11:59 PM Wayne Burdick wrote: > > Hi Rich, > > Just download the latest beta firmware using instructions on our K3 software page.

Conversely, the Stephens group, formed up, made good time, followed the advice of the Paiute guides provided by the Chief, and arrived in Sacramento with more people than when they left [several babies born on the way].? They spread out over northern and central California, were instrumental in founding several towns which became cities today, were active in government, and began some of the agricultural industry that marks the Central Valley today.?

If life were fair, it would be Stephens Pass with Stephens Lake at it's eastern base, after a truly successful example of the western migration.? But life is rarely fair and it's Donner Pass and Donner Lake, named after the dysfunctional party racked by homicides, dumb decisions and, it is alleged, cannibalism, in a futile attempt to survive the winter.?

It is placed about 3.5' away from my left ear with the top of the PS facing away from me. The result is that I can barely hear the PS fans and often forget that the KPA-1500 is running. The amp itself is sitting on top of my Alpha 9500 and is silent. The fans never turn on with my use of the amp. The KPA-1500 PS fans are definitely quieter than my Alpha 9500. I did replace the 9500's external fan to a much quieter one after I bought it 4 years ago. 73 Torrey N9PY -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of alaparos at w2cs.net Sent: April 27, 2018 13:23 To: elecraft Subject: [Elecraft] KPA1500 PS Fan Is there any way to throttle back the power supply fans?

It's caused by an over-current condition sensed by the K3 when both audio channels are loud enough to cause brief over-current conditions. Good luck!

At higher frequencies there is no current on the inner surface so whether they touch when squashed is immaterial, no current there anyway. What is relevant is the shape of the magnetic field as the tube is progressively squashed. As it gets flatter the current distribution moves closer and closer to that of a strip. There are no sudden effects. 73 Alan G0HIQ > Message: 3 > Date: Fri, 27 Apr 2018 01:35:36 +0000 > From: "Dauer, Edward" > To: "elecraft at mailman.qth.net" > Subject: [Elecraft] Current Flow on Copper Strips - a Question > Message-ID: > Content-Type: text/plain; charset="utf-8" > > Since I don't know what precedes the word "thus" in the quotation below I would ask if someone could explain this phenomenon for me. > > I am trying to visualize this with a thought experiment. In an earlier post someone (Skip?) mentioned that early transmission lines were sometimes hollow copper tubes, to respect the fact that AC flows only on the outside of a conductor. So, imagine a hollow tube carrying RF (which may approximate the fast rise and fall times of a high voltage strike). Current is flowing all over the surface, I gather. Now squeeze the tube along its length so that a cross section becomes an ever flatter ellipse. At the last instant squeeze it so that the sides are in contact with each other. What happens to the current flow as that squeezing occurs? Is it still all around the squished tube until the instant the two sides join? And then it all flows primarily along the edges of the now flat conductor?

I struggled with the speaker issue with the USB connection to my PC. Turns out my PC recognizes the KS3 as another input and creates all kinds of havoc causing inability to control the volume, etc. I looked at the speakers and then at the audio mixer and noted the WIN 10 OS was seeing the USB connection and was adding the computer audio to the equation. I opened the mixer on the lower speaker taskbar icon, right clicked, and then muted the microphone (USB Audio CODEC0 and problem solved. This was really a challenge for a bit. I generally don't have the USB output from the K3S plugged in to avoid some other issues, so memory served me correctly. I have a separate set of speakers for the PC and another for the K3S, that IS THE PROBLEM for me. If you don't use this set up, no issue. But IF you use the PC and the Radio, you will get into a mess with separate speaker systems. Hope that makes sense. 73, Bill K9YEQ -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of IK4EWX Sent: Friday, April 27, 2018 12:31 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Second speaker just turns off K3S Dave, you dont make any mistake.

I have used and installed their PEEP system on multiple sites here in Thailand. High exposed sites with a lot of lightning. Notable over the 20 years since the first one was installed there is significantly higher equipment reliability of equipment at those sites and none of what were historically regarded as "typical regular failures". The PEEP system tries to keep any surge energy outside the building. I'm a firm believer in not letting it inside any more than is absolutely unavoidable. In a lot of cases once it gets in the building it is highly unpredictable. Think 4 inch hole burned in pcb back plane, steel rack cabinet door and vapourised wall mounted fire bell. The whole sites have very good protection systems designed primarily around FAA-019E standard, though I would agree with Polyphaser that some of what is contained in that standard is not always ideal. A lot of historical convention gets passed on unquestioned into some of these standards over the years it would seem.

Skin depth is a consequence of how the fields representing the electromagnetic pulse propagate in the electron plasma of the metal, so is a secondary effect, not a primary one. This whole thing is better addressed assuming a perfect conductor, so no wave penetration, and therefore no skin depth at all. Far from the tube, the magnetic field is circular. Immediately outside, it parallel to the surface. Transiting between the two, that means field is compressed at the ends of the major axis. The field density is proportional to the current, so the current will be concentrated near the major axes end points. -- David Woolley Owner K2 06123 On 27/04/18 23:47, Alan B wrote: > My thinking is the current density is uniform in the outer surface of a round tube falling according to skin depth at that frequency. At higher frequencies there is no current on the inner surface so whether they touch when squashed is immaterial, no current there anyway. > What is relevant is the shape of the magnetic field as the tube is progressively squashed. As it gets flatter the current distribution moves closer and closer to that of a strip. There are no sudden effects.

Ask your electrician about using a receptacle mounted flush on the floor. You have likely seen them used in commercial buildings - conference rooms and other places - the cover plate is usually brass with a "door" to expose the receptacle itself. It makes an aesthetically pleasing installation. I would not think you would want to extend the K3 to KPA1500 cables very far. My guess is that double the stock length would be as far as you should consider. 73, Don W3FPR On 4/28/2018 9:54 AM, Dauer, Edward wrote: > The KPA1500 Manual states that ?the power supply can be operated remotely? and that the supplied cables are 66 inches long.

One electrician I hired long ago to look at the question told me it could not be done in an aesthetically acceptable way given the nature of the construction of the basement walls where the station is. That's why I bought the KPA500 rather than a KW amp at the time. There is a 220 VAC outlet in another room on another floor of the house, which might allow me to lay some long cables while I am trying to figure out how to get 220 into the shack.

The KXAT3 can match an SWR up to 10:1 - it is truly a wide range tuner. Use a balun instead of the MFJ-971 to transition from coax to your twin feeder doublet. A balun like the Elecraft BL2 provides a choice of 1:1 or 4:1 ratio. Do not be mislead by those who believe you need to match the characteristic impedance of the feedline - that is just misleading. Instead, you need to match the impedance presented by the twin feeder at the shack location, and that can vary from very low to very high depending on the radiator length, the feedline length and the frequency of operation. If you have trouble matching on some bands, try adding or subtracting a 1/8 wavelength of feedline for the lowest band you have trouble with. The use of 2 tuners in-line will cause additional loss. Any antenna matching device has some loss - using 2 in-line will double that loss. 73, Don W3FPR On 4/28/2018 6:04 AM, John Daws wrote: > Just a query about the use of the MFJ 971 portable tuner with my KX3 (fitted > with automatic ATU) > The twin feeder from the doublet goes into the back of the MFJ which is then > attached via coax patch lead to the KX3 > > I can bypass the Auto ATU fitted on the KX3 menu and manually tune the MFJ > or > > Simply auto tune for each band on the KX3 ignoring the scary looking needle > readings on the MFJ! > > I trust the KX3 more From KY5G at montac.com Sat Apr 28 12:06:27 2018 From: KY5G at montac.com (Clay Autery) Date: Sat, 28 Apr 2018 11:06:27 -0500 Subject: [Elecraft] How far can the KPA1500 amp be from the PS?

The 240 comes from the main box in a 4-wire, 2 sizes bigger copper than required, so I can boost the power at the mains later if need be by swapping breaker set without busting code.? The 2 x 120 legs are twisted pair, and the ground and neutral wires are twisted pairs.? Both pairs are run in steel flex conduit from mains to sub.? From sub to duplexes are also run in steel flex.? ALL duplexes are mounted in metal boxes....? From the metal boxes back to the main panel box is ONE CONTINUOUS electrical connection with very, very low resistance, and of course the main breaker box is grounded as per code.

Like you I tried the EE INit and no joy. I held the Shift/LO button tapped the power button and it would always come back to a blinking red TX LED and MCU LD in a dark display. Yes, I removed the power cable etc. as the manual and the KE7X manual instructs us to do. I went to the archives where I found one of Don's replies about this situation from January 28th 2017. Don stated that in these situations it is a problem with the PC USB port and not the K3S USB port or K3 RS232 port. Don suggested rebooting the PC to clear the USB port. You indicate you have done that with no success. As Don suggested in his 1/28/17 e-mail disconnect the PC USB from the K3, reboot the PC, start the K3 utility, reconnect the USB cable from the K3 to the PC, go into the K3 utility find the Com Port for the K3 and select it. The K3 should now be asking for the firmware load with the yellow delta f LED flashing and MCU LD in the display. Note, the only thing connected to the K3 should be the power cable from the power supply and the USB cable from the PC. Nothing else should be connected to the K3. The P3 needs to be completed disconnected from the K3. The USB cable from the PC needs to go directly to the K3 RS232 port or the K3S USB port. I did this last night and it worked. I need to comment that I didn't reboot the tower PC the K3S is normally connected to, because of the length of time to reboot. So, I performed the above connecting the K3S USB cable directly to my laptop that also has the K3 utility loaded on it. With the K3 utility running when I connected the USB cable from the K3S the utility asked for the Com Port. I selected the K3S port and it started working. Selected download all firmware and all was well when the download was complete. If I left anything out or have listed things in the wrong order etc. I'm sure Don will chime in. I hope this works for you. 73, Mark, WB9CIF -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Don Wilhelm Sent: Saturday, April 28, 2018 3:31 PM To: W1GO (Joe) ; Elecraft Reflector Subject: Re: [Elecraft] Infamous red blinking LED Joe, The blinking red TX LED is an indication of one of 2 conditions.

That may be what I will have to do . . . Hi Ted, This sounds reasonable, but by all means, let your electrician advise you about how to run the line -- that's part of what good electricians are good at. :) I will add this, which I consider very important. Have him pull in at least one 120V circuit with #10 conductors and the 240V circuit. Inside the shack, install two 240V/20A outlets and multiple 120V/20A outlets. These outlets are for station equipment only. It is critical that their green wires be bonded together IN THE SHACK. An easy way to do this is to put the wiring inside the shack in steel conduit (EMT) and use off-the-shelf steel backboxes. Let your electrician tell you local code requirements for wiring back to the panel. 20A breakers are no more expensive than 15A breakers, #10 wire DOES cost more, but it minimizes IR drop, improving voltage regulation. The advantage of using 20A breakers is that you can use 20A outlets, which are downward compatible with 15A plugs. Do NOT use appliance-style outlets for the 240V circuit -- instead use the same style of outlet used for 120V circuits, but with the pin configuration for 240V/20A. This is what I did in my shack, except that I have two duplex 240V 20A outlets in a quad box and four quad boxes with 120V outlets. All the 120V outlets are on a single circuit. FWIW, a single 20A 120V circuit is more than enough to handle all the radio (and computer) gear in an SO2R ham station, even with two 500W amps (as long as they don't transmit at the same time). While what Clay Autrey has advised is certainly not wrong, it may be overkill (and more expensive). Let your electrician advise you on this -- depending on the difficulties associated with the cable run, one or the other may have a cost advantage. 73, Jim K9YC From donovanf at starpower.net Sat Apr 28 15:21:22 2018 From: donovanf at starpower.net (donovanf at starpower.net) Date: Sat, 28 Apr 2018 15:21:22 -0400 (EDT) Subject: [Elecraft] How far can the KPA1500 amp be from the PS?

Due to some temporary relocation of my ham shack for a home refurbish, I am using my KPA500 remotely with the KPA500 remote software server running on a spare netbook near the amp, and the client running on a computer near the rig. There is one 100 ft long RG214 Coax between the KPA500 and the rig for RF and one 100 ft small coax with RCA connectors between them for PTT. The amp and autotuner are at the antenna feed and grounded well. The rig away on the other side of the house not so well RF grounded, but there is no RFI so far. That enables me to see the KPA500 status and change the band on the PC in the shack. They don't yet seem to have the remote software for the KPA1500 yet, but it is supposed to be coming. I would probably accept visible conduit to run power if you can't run it in the walls. As part of the refurbish, drywall was taken out and replaced and the texture matched so new plumbing and electrical could go in. They also replaced insulation. That worked out well, but it was expensive. There is not really any such thing as can't if you have deep enough pockets! 73, Mark W7MLG From edauer at law.du.edu Sat Apr 28 15:59:22 2018 From: edauer at law.du.edu (Dauer, Edward) Date: Sat, 28 Apr 2018 19:59:22 +0000 Subject: [Elecraft] FW: How far can the KPA1500 amp be from the PS?

The remote software idea is interesting. There is a 220 volt outlet already on the outside perimeter deck, which we had put in for the possibility of someday having a hot tub out there ? which we never did. I could put both the amp and the PS in some sort of lockable housing on the deck (which would require hiring a carpenter rather than an electrician.) I will definitely keep an eye on the development of remote software for the KPA1500. I remember when we were building the house we asked our contractor about doing something which would have been unusual, I don?t now recall what. I asked if it could be done.

I have resonant antennas that on other meters and even on my K3 have SWR's that are much lower. For instance, on 40M and 20M I have a beam and a resonant dipole, both of which have bypass SWR's of close to 1:1, but the KAT-500 consistently reports those SWR's as being between 1:7 and 1:8. Even on a dummy load this occurs. Is my KAT-500 reading the SWR differently, or is something wrong with the way these frequencies have been memorized?

Not a good situation for my knees and running power lines. I assume the breaker box is on an outside wall. Here is what I did . I went outside. My shack in on level three, half buried in soil. Ground level comes up to just below the windows. I had an electrician look at the situation and we decided to run the power for that room in conduit...outside. It's 25 feet from the power panel in the basement to the shack. The conduit is connected to the house just below the siding on concrete. Some very large conductors fill the conduit and make their way along the bottom of the house to a point just past the first stud in a closet in the shack. The panel is installed there and I have 2 240V 20A lines and 3 120V 20A lines It's just like running power to an outbuilding or garage except the building Is a particular floor of the house. It got painted when the house got painted last year and it just disappeared. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Dauer, Edward Sent: Saturday, April 28, 2018 1:09 PM To: Dave AD6A ; elecraft at mailman.qth.net Subject: Re: [Elecraft] How far can the KPA1500 amp be from the PS?

Unless the wiring route is short, take Jim Beown's (K9YC) advice about conductor sizes. Large conductors are not required for the current draw, but oversize wire will help reduce the voltage drop when current is drawn. Putting all shack receptacles on a dedicated circuit for both 240 volts and 120 volts AC will help a lot with received noise in your receiver, and will isolate your shack powering from other circuits in the house.

My wife is a now-retired electrical power engineering designer for commercial and industrial projects and says that this is a routine operation in the US. It can be done very neatly to your satisfaction. Sounds like the "electrician" that told you that really didn't want your job.

Message-ID: <201804290022.w3T0MCx7019387@mail42c28.carrierzone.com> Ted, I wonder if the load center panel is mounted on an exterior wall? If so running a penetration from the panel to outside might be better. Then you could route it in conduit or exterior cable routed along exterior to a good spot to bring it back inside at the lower level. That still might require running cable along interior wall surface. I ran about 35-foot of 8-4 cable from my 200A service panel in our utility hall by running it thru pvc conduit thru the floor to our 4-foot high crawl space. Then looped across the underside of floor joists to another floor penetration in the ham shack where I installed a 80A panel. I installed one 240v 20A breaker for my QRO amplifier PS and added two 120v 20A duplex boxes which run my 50A Astron 12v station supply and a MOT 24v 100w repeater PS for 24v stuff. 240vac was run thru conduit to 4-inch box with 20A twist-lock receptacle for the amp cord to plug into. Now I am converting to 50v LDMOS amps and need to provide them 240vac. Two will be kilowatt amps and another 600w. Each to be installed at the base of a different tower so will have 120-foot, 100-foot, and 70-foot 240vac cable runs outside. All get to run inside 2-inch conduit and will have load centers at the amplifier end. Two will route from the hamshack 240v panel. Third has not been determined (might be second 240v line direct from the house main panel). I am designing remote control panels for each amplifier to control and monitor parameters. All are no-tune single band amps so that is much simpler than a KPA500 or KPA1500. But my circumstance is much easier with open crawl space and simple R-19 fiberglass insulated wooden walls; quick work with a hole saw. Working one summer in college as electrical apprentice doesn't hurt knowing what to do. My dad's barn got wired after that summer (for free). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From wa6nhc at gmail.com Sat Apr 28 20:22:57 2018 From: wa6nhc at gmail.com (Rick Bates (WA6NHC)) Date: Sat, 28 Apr 2018 17:22:57 -0700 Subject: [Elecraft] Infamous red blinking LED In-Reply-To: <006701d3df0f$ca01dea0$5e059be0$@sbcglobal.net> References: <006701d3df0f$ca01dea0$5e059be0$@sbcglobal.net> Message-ID: Many desktops of recent vintage don?t truly go ?off? at shutdown.

That's why, for one of the mountain-top comm sites that we designed for a desert site out in the middle of nowhere, we specified - ready for this - 900 Kcmil conductors (*) for a 120/208V 400A feeder because the power company located the CSED (Customer Service Entrance Device) i.e. meter and main breaker installation - at a point down the hill that they could reach in any weather.

Even if the housing is 100% water tight forever, Murphy almost guarantees that the first failure that causes you to want to access the amplifier will occur during a downpour or snow storm. Just run the 240 VAC line into the shack somehow (and the 120 VAC line suggested by K9YC). Worst case, you'll need to run conduit along a wall and maybe ceiling, perhaps covered by a soffit. Some folks even put up a false wall of paneling in front of an existing wall that they can't dig in to.

There are connections that may be just fine at 500 watts, but will either break down or arc over at 1500 watts. What happens if you drive the KPA1500 only to 500 watts? If it behaves the same as it does at 1500 watts, then you may have a problem with the KPA1500, but if things behave normally at 500 watts, then look at your antenna system. 73, Don W3FPR On 4/29/2018 10:13 AM, Mike Crownover wrote: > I have noticed that after my KPA1500 gets above 50C the SWR indicator light starts to show intermittent high SWR.

The amp operates wonderfully, but the indicator lights are a bit bothersome. Anyone have similar issues?

Try that and see whether it shows the same as the display. There are 2 pieces to the SWR - there is the sensor part and then there is the display part. There is a possibility that the sensor is doing OK, but the display end of things may be what is causing the problem.? KPA1500 Utility uses a different path (but the same sensor) for its display of SWR than the front panel display. In either case, it does seem (by my first guess) that there is a solder or cable connection in the KPA1500 that is heat sensitive. How high does the SWR go?? If it stays below 1.5, it will cause no problem despite your concern for that behavior. Unless I am mistaken, the SWR indication on the K3 shows only the SWR of what is connected to the K3, which is the amplifier input 73, Don W3FPR On 4/29/2018 2:25 PM, Mike Crownover wrote: > Don, > > Thanks for the comment.

About a week before he passed, he sent his K2 to me to install one of his K6XX CW Tuning indicators. Unfortunately, he passed away before I could get to it. I talked with Susan (Ron's XYL) this afternoon, and we agreed that I should try to sell Ron's K2/10. She offered to give me a share of the proceeds, but I will not, the full proceeds minus shipping costs will go to the widow. This is K2/10 SN 1392. It has the K160RX, KNB2, KSB2 and KAT2 options installed. It also has the 73CNC VFO knob installed. The BFOMDKT and Thermistor Mod have been installed, but no other upgrade mods have been done. The firmware level is 2.01MCU and 1.02 KIOC. The unbuilt K6XX CW Tuning kit with button LED is also part of the package. I believe a decent asking price for this package is $500.00 including shipping to any QTH with a US shipping address. International shipment will be at additional cost. I will checkout this K2 and do an alignment and calibration at no extra cost to assure you that you are buying a fully functional K2/10. I can also upgrade it to the current level and/or build and install the K6XX CW Tuning Indicator (at extra cost) if you desire.

I'm familiar with the PC interface and have, in the hope of tracking down a problem, built a logger that uses that bus to interrogate the KPA500 at 10 Hz. I was hoping the AUX bus would give a faster detection of a spurious band change than my 10 Hz interrogation ^bn;. I'll look at the bus with my DSO but I have already been given information than suggests its data rate will be too low to be useful.

I will communicate further with you shortly with more information to help clear some of your misunderstanding of the KPA500. 73, Jack, W6FB > On Apr 29, 2018, at 6:47 PM, ANDY DURBIN wrote: > > "fraught with danger"? > > > It's hard for me to imagine how monitoring an "output only" bus with a DSO could be "fraught with danger".

They appear to be flipped/set quite early in the band change sequence/exchange between the K3 and amp, certainly before RF is applied (yay !). At least I've not caught my K3/KPA500(s) doing anything silly in this regard yet. My only gripe with the BAND outputs is that 60m was encoded as 0000 and not 1111 on this 4-bit interface, which means telling the difference between the amp being physically OFF and/or on 60m requires a separate monitoring circuit... >:| 73 Matthew VK5ZM On 30 April 2018 at 09:07, ANDY DURBIN wrote: > Don, > > > Thanks for the reply. > > > I'm familiar with the PC interface and have, in the hope of tracking down > a problem, built a logger that uses that bus to interrogate the KPA500 at > 10 Hz.

It DOES seem reasonable to publish at least an electrical transmission spec for it -- i.e., voltages, source and load impedances, whether it is intended to be terminated (impedance matched) or un-terminated, distance limits for various cable parameters. In fact, it seems unreasonable to NOT put it in the manual RS232, for example, is runs UN-terminated, and the limit on distance is the capacitance of the cable, not it's physical length. Many years ago, the RS232 spec was note that capacitance was the limitation. The way to think about this is that UN-terminated circuits are analyzed as "lumped parameter" systems, where bandwidth limits boil down to degradation of rise time by RC time constants. The source Z is low, the receiving Z is high. TERMINATED systems function as transmission lines, and everything we know about traansmission lines applies. I'm using only the AUX Bus for communication between K3 and KRC2, using a short length of mini Belden 75 ohm coax. If I were, for example, remoting a KPA500 or KPA1500, it? would be nice to run only coax (or a single pair out of CAT5) for that bus, which requires that you know the electrical limits of the circuit. 73, Jim K9YC From jim at audiosystemsgroup.com Mon Apr 30 03:24:35 2018 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 30 Apr 2018 00:24:35 -0700 Subject: [Elecraft] KPA500/K3 AUX bus specification In-Reply-To: References: <276D3D6C9D5C8C4484211E9839FDE1AB49F3CE97@CITESMBX6.ad.uillinois.edu> <3372b498-3e6d-c20d-ab1b-8242eaad5c65@embarqmail.com> Message-ID: On 4/29/2018 8:27 PM, Wayne Burdick wrote: > philosophical, or metaphysical questions How appropriate on a Sunday night! 73, Jim From forums at david-woolley.me.uk Mon Apr 30 05:54:18 2018 From: forums at david-woolley.me.uk (David Woolley) Date: Mon, 30 Apr 2018 10:54:18 +0100 Subject: [Elecraft] KPA500/K3 AUX bus specification In-Reply-To: References: Message-ID: <5ea07ae4-30ac-ce59-1ca0-fab22eb5ea7a@david-woolley.me.uk> You would need to sign a non-disclosure agreement for anything beyond the logic level (TTL) and pinout information.

I thought the 1.3K would have good resale value given its use on DXpeditions.) The logical place for the amp is in my garage, near the antennas feed points and near an electrical subpanel with 60A 240V service. Installing the 240 outlet in the garage is probably a DIY project.

Then you can go to 12W and go thru the bands and see how it does. Also you can run the 5W TX gain cal using the K3 Utility (or TUNE at exactly 5.0W on all bands) to see what happens. The resulting "TXGN LP" numbers are typically below 60, higher numbers indicate something wrong, or you may get an ERR TXG. Go to config menu item "TXGN LP", then step thru the bands to see each one.

Try that and see whether it shows the same as the display. There are 2 pieces to the SWR - there is the sensor part and then there is the display part. There is a possibility that the sensor is doing OK, but the display end of things may be what is causing the problem.? KPA1500 Utility uses a different path (but the same sensor) for its display of SWR than the front panel display. In either case, it does seem (by my first guess) that there is a solder or cable connection in the KPA1500 that is heat sensitive. How high does the SWR go?? If it stays below 1.5, it will cause no problem despite your concern for that behavior. Unless I am mistaken, the SWR indication on the K3 shows only the SWR of what is connected to the K3, which is the amplifier input 73, Don W3FPR On 4/29/2018 2:25 PM, Mike Crownover wrote: > Don, > > Thanks for the comment.

I live in a rural area in the woods so noise is really not a? problem. I was taught a long time ago to keep the AGC off for weak signal reception and it stuck with me.? Those were the S line days.? And in your article you mention ops that can copy into the noise and that certainly describes me, hi.? Its kind of an ESP thing. Thanks for all your valuable info here on the reflector.

Yes, adjusting your AGC Threshold and Slope is preferable to running with AGC off. Fortunately, the K3/K3S has an adjustable limiter to help protect the ears for those operators who would still choose to run with AGC off. 73, Don W3FPR On 4/26/2018 4:44 PM, Mike K8CN wrote: > Don, W3FPR wrote a succinct tutorial about AGC settings on his web page > www.w3fpr.com under the title "Noisy" K3.?

If any of you do not know what we are referring to, go to my website www.w3fpr.com and in the left column, click on the "Noisy K3" article.
