Besides having an excellent quality sound card, you can run traditional FSK RTTY. If you have the 2 meter module installed, you can run VARA FM and 1200 baud packet for Winlink. If you have an older PK-232, you can buy the sound card kit which includes USB upgrades to the PK, adds a USB to serial converter, a USB hub, and software to switch the PK between sound card decoding and tradition packet,RTTY, Pactor etc modes. Ham made parts carries the hook up cables. If you want to make your own, I have a schematic for the sound card,FSK, and CW connections on the PK.

Personally I would, and did, use AFSK on RTTY.? You don't need a sound card beyond the one in your computer.? Use two audio cable from Line In, Line Out, VOX, AFSK and MMTTY and you're done.? I use low tones (915) since I like to "listen" to the receiver.? Some will argue that a better sound card will decode more, I have not found that to be the case, at least comparing the Lenovo T400 to a TASCAM US-100.? Of course, a K3S makes this even easier. I'll confess that in my desire to treat myself to one more new radio in this lifetime, I got tired of waiting for a K4 and bought a TS-890.? Putting it on RTTY was a PITA, since it runs FSK and needs serial port keying.? The radio provides a couple of virtual serial ports via USB so it's doable and works fine once all of the hoops are cleared. Wes? N7WS ps. I'm still an Elecrafter, my KPA500 and KAT500 work very well with the Kenwood. On 1/1/2021 9:13 AM, Craig Wissman wrote: > Sorry to trouble you folks.

I was calling CQ on 40m around 7014 kHz and I noted that several skimmers also reported me weakly on c. 600 Hz either side of this frequency. Sometimes skimmers have bad spurious responses, but seeing this on more than one skimmer caused me to look more closely at my transmit spectrum. I discovered that - particularly on 40m - there were specific frequency ranges where a pair of sidebands appeared that move at 150% of the change in carrier frequency. So on 7012 kHz they are at roughly +/- 500 Hz, at 7011 kHz they are at roughly +/- 1 kHz, at 7010 kHz they are at roughly +/- 1.5 kHz. They cross over with the carrier just below 7013 kHz. Similar patterns recur in other parts of 40m, but they are strongest near the bottom of the band. There are dramatic step changes in the level of the spuria at the boundaries between synthesiser segments - So I see spurii from 7000-7004, none from 7004-7009, spurii 7009 -7015, etc. They peak in strength when they are about +/- 500 Hz from the carrier, but drop significantly in level as you get further from the carrier. The level of these spurii is what was concerning - at their worst they were less than 30dB down on the transmit signal. They grow somewhat non-linearly with power. At 5W they are -40dBc, at 12W they are -32dBc, at 13W they are -35dBc and at 100W they are a little less than -30dBc. I can see the same style of spuria in some segments on 80m and 160m - but at lower levels. I assumed this was a fault with that specific radio - and in some ways it is - but the same spurii are present on both K3s that I have here - but on the second radio they are no worse than -45dBc. I've disconnected everything connected externally from the radio, tried different power supplies, and recalibrated the synthesiser and Tx gain with no significant change. Both radios have the original synthesisers - not the KSYN3A. Any leads from anyone on this one? 73, Andy, G4PIQ From frantz at pwpconsult.com Fri Jan 1 12:34:51 2021 From: frantz at pwpconsult.com (Bill Frantz) Date: Fri, 1 Jan 2021 12:34:51 -0500 Subject: [Elecraft] External sound card advice needed to attach to K3 In-Reply-To: <0b144503-8164-cba3-91a8-6a0494f0a270@subich.com> Message-ID: I have been quite successful with a $5 dongle from Amazon which I use with my KX3. I had to install a attenuator which is a 1K ohm resistor between the mic in and ground and a 47K ohm resistor between KX3 headphone out and mic in. (Note that these values aren's critical. Fred Cady recommends 33 ohm and 270 ohm respectively.) Since everything fits in the shell of the 3.5mm plug, it makes a very light, compact system which is nice with a portable radio. 73 Bill AE6JV On 1/1/21 at 11:38 AM, lists at subich.com (Joe Subich, W4TV) wrote: >Any sound card with Line In and Line Out will work with the K3.

It all boils down to understanding what you are doing. Windows sounds can be turned off. The best sound card in the world isn't going to stop anyone from transmitting garbage. Understanding includes setting the audio levels correctly throughout the system. I've used my PC sound system with two simple audio cables for years.

Using the computer sound card on a radio is not 'set and forget'. We still have a large base of folks that don't get what is required to operate a clean (legal) station; we all learn as we go.? Setting boundaries is part of that edcucation (OS stays in OS, radio stays in radio). Turning off the OS sounds, one would also lose features that the OS and apps that are useful (like JTAlert "DX" announcements, Zoom/Skype audio).? The small cost of a sound device (or second sound card) for the radio(s) is certainly worth the gains and lowering of the risks. 73, Rick NK7I On 1/1/2021 9:34 AM, Mike Harris via Elecraft wrote: > Not really.

But I'm curious how you're measuring and observing (not doubting) these results. Except for the reports seen on the air to validate your observations; if the radio change barely affects the results and the condition does not, it's either a failure of both radios or the testing environment (i.e. transmitting into the same antenna). What happens with changes in power output, different (dummy) loads?? Then the eternal question; since this hasn't been noted before at your station; what else is different or has changed?? Have you tightened your antenna connectors lately?

Transmission of music is specifically unlawful.? (What is defined as music these days, also subject to interpretation, hi hi.) Defined in the simplest of terms, any sound transmitted other than for the purposes of communication (voice, tones for digital) is illegal. This includes background music in the same room as the microphone (though generally ignored as part of the environment, in the US; same as telephone 'hold' music in an autopatch; traffic noise etc.) and certainly includes the 'musical' sounds from most OS (they offer no communication). Which, to me, means the sounds from an OS are unlawful to transmit.? If the incidental OS sound is spoken ("You have mail"), that isn't legal in the digital, non-phone) portions of the bands.? At the very least, they use more spectrum than necessary (i.e. 3 KHz bandwidth in an area for FT8, which uses ~60 Hz bandwidth per user) and offer nothing for communication. Considering the general apathy of the FCC lately (US of course), I'm not surprised that this has never been tested by citation.? I'd much rather err on the side of caution.? Turning off the OS sounds is not a complete solution. Using a sound card, specific and limited to the radio use, is a vast improvement over using the OS sounds device to maintain legality. 73, Rick NK7I On 1/1/2021 10:04 AM, Phil Kane wrote: > On 1/1/2021 8:56 AM, Rick Bates, NK7I wrote: > >> A generically 'bad' idea and is the reason that voice, operating >> system sounds (all illegal) and poor audio are often in the digital >> portions of the bands. > > Please explain your comment "all illegal" concerning "operating system > sounds".

The user also loses the benefits provided by the OS sounds (as said in another email here on the list). The average ham radio costs at least hundreds of dollars to buy, an adequate sound card is under $10-20.? It's not an economic strain.? The cost of wire for a simple antenna, costs much more. Many newer radios come with a sound device built in; just use that and let the OS do things as designed for audio. 73, Rick NK7I On 1/1/2021 10:20 AM, Wes wrote: > Turn off Windows sounds in Control Panel and operate.

To answer those questions. I'm measuring this with the radio into a power attenuator and then with additional attenuation into a Perseus SDR operating as a spectrum analyser - well below its overload threshold and with plenty good enough phase noise and dynamic range to see this. I've also confirmed the signals are there on the second K3. I ripped out all the normal station cabling as part of the testing - so - yes everything is tight. I suspect I haven't noticed this before for two reasons. Firstly - the level of the spurii are very variable by specific frequency in the band - so you have to be a bit unlucky - and unless you're listening for it yourself on site - most times it would be too weak for people to comment / skimmers to pick it up. Also - the times I have run this radio with a second receive in band while transmitting it's normally been with the run radio above 7025 where the spurii are at a much lower / no existent level. Secondly - I wonder if something is degrading in that radio. The fact that the spurious level changes significantly with drive levels suggests this is being generated by a non-linearity in the PA chain, and I wonder if I'm short of gain somewhere in the driver strip so the ALC is forcing the low levels in the strip to be driven harder. It is present on both radios, but is 15dB worse on one radio than the other. Andy, G4PIQ ------------------------- NK7O wrote :- I don't have an answer, I have no test gear that would even allow a look (other than another radio). But I'm curious how you're measuring and observing (not doubting) these results. Except for the reports seen on the air to validate your observations; if the radio change barely affects the results and the condition does not, it's either a failure of both radios or the testing environment (i.e. transmitting into the same antenna). What happens with changes in power output, different (dummy) loads? Then the eternal question; since this hasn't been noted before at your station; what else is different or has changed? Have you tightened your antenna connectors lately? HNY, Rick NK7I On 1/1/2021 9:30 AM, g4piq--- via Elecraft wrote In general I've found the spurious performance of the K3 to be pretty good, but I've noticed something today that I thought it would be worth asking more widely if anyone else has seen and fixed. I was calling CQ on 40m around 7014 kHz and I noted that several skimmers also reported me weakly on c. 600 Hz either side of this frequency. Sometimes skimmers have bad spurious responses, but seeing this on more than one skimmer caused me to look more closely at my transmit spectrum. I discovered that - particularly on 40m - there were specific frequency ranges where a pair of sidebands appeared that move at 150% of the change in carrier frequency. So on 7012 kHz they are at roughly +/- 500 Hz, at 7011 kHz they are at roughly +/- 1 kHz, at 7010 kHz they are at roughly +/- 1.5 kHz. They cross over with the carrier just below 7013 kHz. Similar patterns recur in other parts of 40m, but they are strongest near the bottom of the band. There are dramatic step changes in the level of the spuria at the boundaries between synthesiser segments - So I see spurii from 7000-7004, none from 7004-7009, spurii 7009 -7015, etc. They peak in strength when they are about +/- 500 Hz from the carrier, but drop significantly in level as you get further from the carrier. The level of these spurii is what was concerning - at their worst they were less than 30dB down on the transmit signal. They grow somewhat non-linearly with power. At 5W they are -40dBc, at 12W they are -32dBc, at 13W they are -35dBc and at 100W they are a little less than -30dBc. I can see the same style of spuria in some segments on 80m and 160m - but at lower levels. I assumed this was a fault with that specific radio - and in some ways it is - but the same spurii are present on both K3s that I have here - but on the second radio they are no worse than -45dBc. I've disconnected everything connected externally from the radio, tried different power supplies, and recalibrated the synthesiser and Tx gain with no significant change. Both radios have the original synthesisers - not the KSYN3A. Any leads from anyone on this one? 73, Andy, G4PIQ From wes_n7ws at triconet.org Fri Jan 1 13:57:51 2021 From: wes_n7ws at triconet.org (Wes) Date: Fri, 1 Jan 2021 11:57:51 -0700 Subject: [Elecraft] External sound card advice needed to attach to K3 In-Reply-To: <8fceb1bd-6d21-431b-10dc-68f8749a1dc0@gmail.com> References: <85d3017f-375c-75e9-6e6c-4f1ac83c6007 @triconet.org> <0552a457-f894-ad8d-e7ad-97d211d774c9@gmail.com> <2ea4ba34-4717-d6b8-952b-213adec774e3@horizon.co.fk> <8fceb1bd-6d21-431b-10dc-68f8749a1dc0@gmail.com> Message-ID: <8ea74a28-71aa-0a86-00ff-4e96424d7286@triconet.org> We should go back to a toggle switch on the front panel for transmit/receive because having VOX turned on might allow an inadvertent transmission of shack noise.?

Upon taking the lid off the other (newer) radio, I realised that the KSYN3 in the new radio (SN 8529) had a shield installed that neither of the KSYN3s in the older radio (SN 4198). Looking at both construction manuals - somewhere between 2010 an 2013 a shield was added to the KSYN3, so this looks like leakage from the DDS pre-filtering, and some aluminium is the pragmatic answer to get the issue down to acceptable levels. As an experiment, I have just grounded the 4 crystal cases (recognising this may change the characteristics of the passband a little) - and it has improved the performance by 15dB - putting the two radios in line with each other. 73, Andy, G4PIQ From: g4piq at btinternet.com Sent: 01 January 2021 18:31 To: 'g4piq at btinternet.com' Subject: RE: K3 Tx Spurious on Specific Frequencies on 160/80/40 Thanks Rick. To answer those questions. I'm measuring this with the radio into a power attenuator and then with additional attenuation into a Perseus SDR operating as a spectrum analyser - well below its overload threshold and with plenty good enough phase noise and dynamic range to see this. I've also confirmed the signals are there on the second K3. I ripped out all the normal station cabling as part of the testing - so - yes everything is tight. I suspect I haven't noticed this before for two reasons. Firstly - the level of the spurii are very variable by specific frequency in the band - so you have to be a bit unlucky - and unless you're listening for it yourself on site - most times it would be too weak for people to comment / skimmers to pick it up. Also - the times I have run this radio with a second receive in band while transmitting it's normally been with the run radio above 7025 where the spurii are at a much lower / no existent level. Secondly - I wonder if something is degrading in that radio. The fact that the spurious level changes significantly with drive levels suggests this is being generated by a non-linearity in the PA chain, and I wonder if I'm short of gain somewhere in the driver strip so the ALC is forcing the low levels in the strip to be driven harder. It is present on both radios, but is 15dB worse on one radio than the other.

HNY, Rick NK7I On 1/1/2021 9:30 AM, g4piq--- via Elecraft wrote In general I've found the spurious performance of the K3 to be pretty good, but I've noticed something today that I thought it would be worth asking more widely if anyone else has seen and fixed. I was calling CQ on 40m around 7014 kHz and I noted that several skimmers also reported me weakly on c. 600 Hz either side of this frequency. Sometimes skimmers have bad spurious responses, but seeing this on more than one skimmer caused me to look more closely at my transmit spectrum. I discovered that - particularly on 40m - there were specific frequency ranges where a pair of sidebands appeared that move at 150% of the change in carrier frequency. So on 7012 kHz they are at roughly +/- 500 Hz, at 7011 kHz they are at roughly +/- 1 kHz, at 7010 kHz they are at roughly +/- 1.5 kHz. They cross over with the carrier just below 7013 kHz. Similar patterns recur in other parts of 40m, but they are strongest near the bottom of the band. There are dramatic step changes in the level of the spuria at the boundaries between synthesiser segments - So I see spurii from 7000-7004, none from 7004-7009, spurii 7009 -7015, etc. They peak in strength when they are about +/- 500 Hz from the carrier, but drop significantly in level as you get further from the carrier. The level of these spurii is what was concerning - at their worst they were less than 30dB down on the transmit signal. They grow somewhat non-linearly with power. At 5W they are -40dBc, at 12W they are -32dBc, at 13W they are -35dBc and at 100W they are a little less than -30dBc. I can see the same style of spuria in some segments on 80m and 160m - but at lower levels. I assumed this was a fault with that specific radio - and in some ways it is - but the same spurii are present on both K3s that I have here - but on the second radio they are no worse than -45dBc. I've disconnected everything connected externally from the radio, tried different power supplies, and recalibrated the synthesiser and Tx gain with no significant change. Both radios have the original synthesisers - not the KSYN3A. Any leads from anyone on this one? 73, Andy, G4PIQ From g4piq at btinternet.com Fri Jan 1 16:22:20 2021 From: g4piq at btinternet.com (g4piq at btinternet.com) Date: Fri, 1 Jan 2021 21:22:20 -0000 Subject: [Elecraft] K3 Tx Spurious on Specific Frequencies on 160/80/40 Message-ID: <04a101d6e084$30343100$909c9300$@btinternet.com> And a small correction to this in case anyone else gets inspired to do anything.

His radio had the same problem.? It didn't take high levels, noises in the shack would modulate it; they were more random and harder to see than single frequencies, but they were there. Of course the new upgraded boards are free of this. Considering the lightweight construction, the almost total lack of shielding and the questionable TMP connectors, the K3(S) is remarkably free of birdies and spurious garbage.? It's there just usually not objectionable. Wes?

And these are the people that we trust to operate a radio transmitter capable of causing harmful interference that can cause serious health and welfare damage? How much skill is necessary to turn off a function the procedure of which can be defined in four or five short easy-to-follow sentences?

Those adequate for data mode use are available in the $10 to $20 range, and it solves a lot of problems. Sure there are exotic soundcards costing $100 or more, but those are overkill for data modes. If you have a computer dedicated to the ham station setup, you can avoid this problem by simply turning off the OS sounds, but if you are using that computer for other tasks, then you likely want to leave the sounds turned on. With each OS update, check to be certain the OS sounds are still turned off. Just make sure your OS does not set the external soundcard as default. Windows often does that when you first install it - check the soundcard settings. 73, Don W3FPR On 1/1/2021 7:43 PM, Phil Kane wrote: > On 1/1/2021 10:22 AM, Rick Bates, NK7I wrote: > >> While I'm not an attorney, I've read the rules (subject to >> interpretation of course). > > That's always a good start. > >> Considering the general apathy of the FCC lately (US of course), I'm >> not surprised that this has never been tested by citation. > > Why should it be??

I did notice the microphonics while I was testing - of course a good solid thump to the radio is an important part of any debugging process to find dodgy connections - and I could see the effect of microphony on the stability of the carrier. I was only talking about that stifferer - which I assume also works as a shield - not anything additions. To ground the crystal, I just used a short wire from a ground via to the nearest crystal can - and to test grounding all 4 I stuffed a piece of aluminium foil in between all 4 xtals. When I measured it properly - the single ground improved the worst case performance at 100W from -28dBc to -35dBc, but the addition of the foil to ground them all made it a bit worse (back to about -30 dBc). Swapping in the shielded KSYN3 from the other radio gives about -45dBc worst case at 100W - much the same on both radios. The best answer might be to buy some KSYN3As - but of course they're not readily available right now - though I am aware of the pre-order interest form. And they could have similar issues of course. I haven't bothered to this point since even with the KSYN3s performance is good enough to operate SO2R in-band within 1-2 kHz with less than 100m of antenna separation here. 73, Andy, G4PIQ From: g4piq at btinternet.com Sent: 01 January 2021 21:22 To: 'elecraft at mailman.qth.net' Subject: RE: K3 Tx Spurious on Specific Frequencies on 160/80/40 And a small correction to this in case anyone else gets inspired to do anything. Grounding just one of the crystals improved the performance by about 8dB - but did not get as good as the KSYN3 with a shield. It clearly needs the full treatment. 73, Andy, G4PIQ From: g4piq at btinternet.com > Sent: 01 January 2021 20:57 To: 'elecraft at mailman.qth.net' > Subject: RE: K3 Tx Spurious on Specific Frequencies on 160/80/40 I think I have worked it out. Taking the lid off and poking about showed that if I touched the crystals at the DDS end of the filter on the synthesiser board, the spurious levels rose. Upon taking the lid off the other (newer) radio, I realised that the KSYN3 in the new radio (SN 8529) had a shield installed that neither of the KSYN3s in the older radio (SN 4198). Looking at both construction manuals - somewhere between 2010 an 2013 a shield was added to the KSYN3, so this looks like leakage from the DDS pre-filtering, and some aluminium is the pragmatic answer to get the issue down to acceptable levels. As an experiment, I have just grounded the 4 crystal cases (recognising this may change the characteristics of the passband a little) - and it has improved the performance by 15dB - putting the two radios in line with each other. 73, Andy, G4PIQ From: g4piq at btinternet.com > Sent: 01 January 2021 18:31 To: 'g4piq at btinternet.com' > Subject: RE: K3 Tx Spurious on Specific Frequencies on 160/80/40 Thanks Rick. To answer those questions. I'm measuring this with the radio into a power attenuator and then with additional attenuation into a Perseus SDR operating as a spectrum analyser - well below its overload threshold and with plenty good enough phase noise and dynamic range to see this. I've also confirmed the signals are there on the second K3. I ripped out all the normal station cabling as part of the testing - so - yes everything is tight. I suspect I haven't noticed this before for two reasons. Firstly - the level of the spurii are very variable by specific frequency in the band - so you have to be a bit unlucky - and unless you're listening for it yourself on site - most times it would be too weak for people to comment / skimmers to pick it up. Also - the times I have run this radio with a second receive in band while transmitting it's normally been with the run radio above 7025 where the spurii are at a much lower / no existent level. Secondly - I wonder if something is degrading in that radio. The fact that the spurious level changes significantly with drive levels suggests this is being generated by a non-linearity in the PA chain, and I wonder if I'm short of gain somewhere in the driver strip so the ALC is forcing the low levels in the strip to be driven harder. It is present on both radios, but is 15dB worse on one radio than the other. Andy, G4PIQ ------------------------- NK7O wrote :- I don't have an answer, I have no test gear that would even allow a look (other than another radio). But I'm curious how you're measuring and observing (not doubting) these results. Except for the reports seen on the air to validate your observations; if the radio change barely affects the results and the condition does not, it's either a failure of both radios or the testing environment (i.e. transmitting into the same antenna). What happens with changes in power output, different (dummy) loads? Then the eternal question; since this hasn't been noted before at your station; what else is different or has changed? Have you tightened your antenna connectors lately? HNY, Rick NK7I On 1/1/2021 9:30 AM, g4piq--- via Elecraft wrote In general I've found the spurious performance of the K3 to be pretty good, but I've noticed something today that I thought it would be worth asking more widely if anyone else has seen and fixed. I was calling CQ on 40m around 7014 kHz and I noted that several skimmers also reported me weakly on c. 600 Hz either side of this frequency. Sometimes skimmers have bad spurious responses, but seeing this on more than one skimmer caused me to look more closely at my transmit spectrum. I discovered that - particularly on 40m - there were specific frequency ranges where a pair of sidebands appeared that move at 150% of the change in carrier frequency. So on 7012 kHz they are at roughly +/- 500 Hz, at 7011 kHz they are at roughly +/- 1 kHz, at 7010 kHz they are at roughly +/- 1.5 kHz. They cross over with the carrier just below 7013 kHz. Similar patterns recur in other parts of 40m, but they are strongest near the bottom of the band. There are dramatic step changes in the level of the spuria at the boundaries between synthesiser segments - So I see spurii from 7000-7004, none from 7004-7009, spurii 7009 -7015, etc. They peak in strength when they are about +/- 500 Hz from the carrier, but drop significantly in level as you get further from the carrier. The level of these spurii is what was concerning - at their worst they were less than 30dB down on the transmit signal. They grow somewhat non-linearly with power. At 5W they are -40dBc, at 12W they are -32dBc, at 13W they are -35dBc and at 100W they are a little less than -30dBc. I can see the same style of spuria in some segments on 80m and 160m - but at lower levels. I assumed this was a fault with that specific radio - and in some ways it is - but the same spurii are present on both K3s that I have here - but on the second radio they are no worse than -45dBc. I've disconnected everything connected externally from the radio, tried different power supplies, and recalibrated the synthesiser and Tx gain with no significant change. Both radios have the original synthesisers - not the KSYN3A. Any leads from anyone on this one? 73, Andy, G4PIQ From k2asp at kanafi.org Fri Jan 1 20:23:28 2021 From: k2asp at kanafi.org (Phil Kane) Date: Fri, 1 Jan 2021 17:23:28 -0800 Subject: [Elecraft] External sound card advice needed to attach to K3 In-Reply-To: References: <85d3017f-375c-75e9-6e6c-4f1ac83c6007 @triconet.org> <0552a457-f894-ad8d-e7ad-97d211d774c9@gmail.com> <249be181-dd71-c08c-bebe-19c8c1d65944@triconet.org> Message-ID: On 1/1/2021 1:57 PM, Joe Subich, W4TV wrote: > The number of amateurs using some kind of DX alerting system and/or > streaming music while waiting for someone else to find them "a new > one" to work in significant and you can hear most of their alerts > or music on the air from time to time.

For radios like the K3S, this additional 'sound card' is built into the radio, so there's no reason not to use it. For those of us (like me) with a K3 without a USB port, an external USB card is a great option. However, it is entirely possible for someone to configure Windows to use that card as the default as well, defeating the purpose of separate sound cards. In fact, Windows may "helpfully" do so itself when a new sound card is detected. So, adding a second card is great, but the PC must still be correctly configured. Bottom line is that people need to learn enough about their equipment (INCLUDING their computer) to configure it correctly, and to troubleshoot issues that arise. No different than learning to properly adjust a transmitter or amplifier for a clean signal - it goes with the territory. I believe the original poster simply wanted a recommendation on what sound card works well for digital modes. I think you'd be hard pressed to find a modern sound card that didn't - digital modes are not exactly demanding in terms of a high end sound card. Personally, I use this one with my K3 - https://www.amazon.com/UGREEN-External-Adapter-Headphone-Microphone/dp/B01HPMHOY0 UGreen model 30420. They go for about 20 bucks. It's a combination of a sound card and a 3 port USB hub. I have it installed in the rack where my K3, P3, and Winkeyer live. The USB to RS-232 cable for the K3/P3 plugs into one of the ports on the hub, and the Winkeyer to another. Standard 1/8 inch audio cables connect the audio in/out from the UGreen device to the audio in/out on the K3. The single USB cable from the UGreen device goes to the PC via a short USB extension (the cord on the device is only 6 inches long). I've used this for over three years with no problems, for AFSK RTTY, SSTV, FT8, etc. as well as rig control and CW keying. All with one USB cable from the rack to the PC. Very convenient.

Take the time to open the case and tighten every bolt, nut, screw and reseat the connectors (wiggle everything).? Then retest.? Over time, some radios self-loosen bolts etc. in particular those that bond boards to mounts (thermal flexing).? ;-)? However Elecraft is not just 'some radio', but it's worth a peek. I would also suggest a redo of the power calibration sequence, to have those values at the ready for Elecraft (save the config file to send to them).? I say this because recent reports of LPA failure of a few K3's have appeared on this list (one may be carrying more load if another has failed).? If that has happened, non-linearity could be increased (as the radio strives to make the power level as set), amplified through each stage. By then the support staff at Elecraft should be back on duty for further comments and testing. It's curious (disturbing) that both of yours exhibit the same issues (though one is 'better'). Good luck, please report back any useful comments or fixes. HNY, Rick NK7I On 1/1/2021 10:34 AM, g4piq--- via Elecraft wrote: > Thanks Rick.

Save your money! Ray WA6VAB K3 It is perfectly possible to do this. It is electronically possible. And yes, it works fine. But just because you CAN doesn't mean you SHOULD. It is incredibly easy to accidentally transmit music or other spurious sounds because some other piece of software also uses the standard sound card. You're welcome to use your computer and your radio as you see fit, but keep in mind that you do have a responsibility to follow the FCC regulations, and if something you do attracts the attention of a VM or the Enforcement Bureau, you may get a "Certificate of Naughtiness" or some such from the Powers That Be. It's much safer for your license status to spend $10 bucks or so on a USB sound card that you solely use for ham radio digital modes. That keeps any musical Windows alerts, notifications of subscribed Youtube videos, Ebay notifications for auctions you are watching, the baby monitor, or any of a dozen other things that are automatically connected to the Default Sound Devices, from sending anything that might jeopardize your license. If the cat walks on your keyboard while you're getting a cup of coffee, and turns on Spotify, you might come in to see that your cat just Rickrolled the 80-meter FT8 window, and was in the process of telling the world about your WAP when you discovered it. Things happen. Accidents happen. You can overlook something. This is just how things are. But you and I both know that Murphy loves moments like these, and that the perversity of the Universe tends to the maximum. Spend $10 to help keep your $2000 radio from sending extraneous sounds from your $900 PC over the air, because you and I also know that at the precise moment you think "nothing can possibly go wrong" and go get your coffee, three VMs will have JUST tuned up their machines to do a little 80m FT8, and your cat thinks your keyboard feels good under her paws. -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Fri, Jan 1, 2021 at 7:18 PM Ray wrote: > I use my standard computers sound card for Digital Mode, works Fine. > Save your money!

Those adequate for data mode use are available in the $10 to $20 range, and it solves a lot of problems. Sure there are exotic soundcards costing $100 or more, but those are overkill for data modes. If you have a computer dedicated to the ham station setup, you can avoid this problem by simply turning off the OS sounds, but if you are using that computer for other tasks, then you likely want to leave the sounds turned on. With each OS update, check to be certain the OS sounds are still turned off. Just make sure your OS does not set the external soundcard as default. Windows often does that when you first install it - check the soundcard settings. 73, Don W3FPR On 1/1/2021 7:43 PM, Phil Kane wrote: > On 1/1/2021 10:22 AM, Rick Bates, NK7I wrote: > >> While I'm not an attorney, I've read the rules (subject to >> interpretation of course). > That's always a good start. > >> Considering the general apathy of the FCC lately (US of course), I'm >> not surprised that this has never been tested by citation. > Why should it be??

We always included information about Ohm's law, how to cut a 1/2 wave dipole, and operating procedures. They're all on the tech test, and for many students it's a lot easier to learn how to figure out the answer than it is to remember which multiple-guess is correct. Quick example: There is a question about how long a 1/4 wave antenna is for 2M. We tell them that 40" is a good enough conversion for a meter, so 2M is 80" and 1/4 or 80" is 20". The correct answer on the test is 19" but the other 3 answers are way wrong, so picking the closest answer works. We even get to mention that the velocity of light in a wire is slower than it is in free space, so 19" is the right answer. What I find with students is that many are completely at sea about how ham radio works in the practical sense of picking up a microphone and making a contact. There's nothing like just doing it. We would run a 2nd class a month after the ham cram and license test. We would tell the students to bring their new radios and we would get the local repeaters programmed into them. We would then coach them in making some contacts with each other. As weeks went by, we would encourage them to act as net control for our weekly net, and then to act as net control for the county net when it was our group's turn. Again, like any student, spoon feed them at a rate such that they can learn. It takes a lot of Elmering to make a ham. 73 Bill AE6JV On 1/1/21 at 10:58 PM, rmcgraw at blomand.net (Bob McGraw) wrote: >I was asked by a club to teach a new hams class in preparation >for the license exam.??

Actually my solution is easier: I have a separate computer for running my ham radio programs so never need to hear that computer "burp". Internet and e-mail done on a separate computer where I can enable sound if I want (most of the time speaker is cancelled). I have a FM radio for music. Occasionally, I want to hear audio with a video and enable speaker for that. Currently using the soundcard (Realtek) in the computer for digital modes (but not very satisfactory as gain is not leveled and has a lot of noise below 200-Hz). Eventually will get my new A/D going (UADC4) which will drive with baseband audio from my LP-Pan(SDR) running on the K3 1st IF. With my old winXP computer I used a emu0202 soundcard or a Delta44 (but neither are supported by win10). Now run two Dell Inspiron i5 with separate monitors. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From wes_n7ws at triconet.org Sat Jan 2 00:46:20 2021 From: wes_n7ws at triconet.org (Wes) Date: Fri, 1 Jan 2021 22:46:20 -0700 Subject: [Elecraft] External sound card advice needed to attach to K3 In-Reply-To: References: <14337E00-FEA4-4B83-B6F0-0CF9EFA36E1F@gmail.com> Message-ID: <8ede489a-f95a-deac-91e6-6b27670ca4b3@triconet.org> I'm long retired but if I wasn't, who are you and why would I want to work for you anyway??

I hope someone reading this will direct me and others to a site or two that help us understand what is going on. I just used a cheap Amazon sound card when hooking up two different FT8 xcvr kits (QRPGuys and CWTD) to my W10 laptop and watched paint dry last winter while in Florida. Noting exciting so when we came back home in the spring never hooked them up again. Still if the bug hits again I would like to understand more. I read every email on this and other sites re FT8, etc., so again, if someone can direct me to a good site or two to assist my weak understanding I would be interested.

I am 67 years old, for 7 years I played WoW, for 6 years I played Everquest and for 5 years I have played Guild Wars 2. I enjoyed each of these games. I moved on to the more progressive game but still enjoy playing them from time to time. I only play GW2 at this time. Making the games set up and work with all peripherals is no harder than setting up FT8. Setting up RTTY with 2 or 3 decoders and getting everything to work...much harder. I am finding that many people in their 40s and 50s are getting into Amateur Radio. Some want the challenge of making stuff work, some want the antenna building experience, some want kit building but most seem to be from a subset of the population that are what one might call internet geeks. These guys do great in the transition to ham radio. Many gamers spend upwards to 2k$ on a video card only for their game box. So, $$$ is generally not a limiting option for this group. When they get hooked, they are hooked hard. In NCJ a few years ago, there was an article about contesting and video games. The parallels between the 2 of being "in the zone" were made. The same psychological high is involved but actually, it is more involved and dynamic than an online game. Pile ups, gotta love them, any mode you can get them, cw or ssb will provide that psychological high that melts the time away and keeps you on your toes. One can get so involved that you have to force yourself to take a deep breath and relax the shoulders and refocus on your posture so you can continue to run. 6, 7, 8, 9, 10 hours later, you have to pee, get a drink, grab a snack and get at it again. It is addicting. I am glad that cw contests are not every weekend because my life would end. LOL. SERIOUS online gaming requires raiding to really advance in MMORPG games. Serious ranking for WRTC takes the same. It takes tech, engineering, $$$ and commitment to advance in the world of contesting. What reward? Well, if you like to compete then this is your mojo. If you like to collect wallpaper for working all places, counties, countries, etc it is there. If you want to be recognised in a magazine for contest performance that is here. In the ham radio world there are no cash prizes. Not so in the gaming world, there really are professional gamers. Heh for that matter, I used to farm gold in games and sell it for $$$. I did this while waiting to Raid. In games you have dps meters and one always tried to be on the top of the pile by being best in your class for whatever your function was. N1MM has a rate meter and mults window based on band population and feedback and spotting networks. How does one get these gamers to transition to Amateur Radio? Good question. When I state that my hobby is Ham Radio, I get, "I did not think people did that now. Or Really, what is that? Why would you do that?" the conclusion that I get from these comments is: there is not enough exposure of the population to Amateur Radio. Plain and simple people just don't hear about it or see it in action. There are no public special events. There are not enough elmers to encourage people. There are no longer any towers being put up because of HOA and zoning ordinance rules. Towers used to be focal points for people to talk about. Why does he have a tower? Once that question was asked then a tour of the shack generally was involved and maybe 1 in 10 or 20 became interested to progress into the hobby. Rarely do you see a tower any more. Less exposure, less questions, about the hobby. People in general are curious. If we want Amateur Radio to survive, we as a whole have to whet that curiosity. We have to be Elmers. We have to welcome people and encourage them to get involved. We have to be honest about the realistic expectations of the hobby both in what it can and can not do, what is going to be the realistic cost to get going from marginal rig/station to contest capable station. The greatest disservice that is currently being done is licensing. I traveled for 23 years up and down the east coast. I have attended many radio club meetings and the focus has been licensing, getting more hams. Sadly, that is not the answer. Many of those that got the license never operated. Then there are the shack-on-the-crack 2 meter hams that just get on repeaters and yack all day long. The same 3 or 4 guys on the repeater day in and day out talking about the same thing. Heck if I were a new ham, I would give it up in short order and try to sell my baufong asap. The problem is even though we get people licensed there is little or No followup with helping them get on the air. When I got my license over 50 years ago, I studied the Ameco Radio theory course. I bought the ARRL handbook. That was my bible, my religion when I was 12 years old and living on the farm. Today you buy a license manual. It has all the questions and answers. Marking out all the wrong answers so that only the question and right answer appears and after reading just the question and the answer through 6 times and never reading anything else, there is a good chance that a person will pass the exam and never know a damned thing about radio but they will be an Extra. Whoopie. I expect a fire war when I say this and that is, most extra class hams licensed with in the last 15 years are dumber than a bag of hammers when it comes to radio theory, operation, station building, safe practices or anything as simple as soldering or crimping on a PL259. Much less do they know what an SO239 is and what it is used for. Then there are those that sell new hams broken or marginal radios and that despoils them on the hobby. There are tons of pitfalls to getting new hams into the hobby. The problem is not licensing, it is helping the peer get going so they can have fun. Whether it be CW, SSB, Contesting, Satellite work, building antennas or kits or just helping choose equipment and antennas and helping with that first QSO, those are the things we need to be doing. I have no proof of this, but, if a new ham does not get on HF quickly after getting licensed he or she will not be long for the hobby. Getting them invested in more than listening to a squelch tail is what needs to be done. I praise Elecraft in their business model. First and foremost, they do not produce crap radios. They are clean. They can be used in tough conditions. For the most part with reasonable care and feeding, they are bombproof. Plus, they have a price point for almost every entry into the HF spectrum of the hobby. Their KX2 is a marvel for mountain top operating or the traveling ham that wants a park-bench QSO in his down time. It is a quality radio under the 1k$ mark. Next is their KX3. It has a way better RX, extra bands and more power and sells well equipped for under 2K$. Then enter the K3S, now discontinued. It was the gold standard of all contest radios well equipped for Under 4k$. Now they have the K4 iterations which I believe will set a new standard for further manufacture of ham radios. In wondering if Eric and Wayne were gamers, they made a radio that can be upgraded by plugging in new cards which is congruent with upgrading a computer game machine. Because their focus has been quality before beauty, seemingly, they produce an excellent radio, which is durable and does not have the LS branding of chrome and fancy knobs to detract from lack of performance found in other brands. Any of their radios can be used to contest and they are not painful to use. Every time I have called Elecraft, I get someone who answers my questions. Honest, to the point answers and service beyond what any other manufacturer has today. I am not forwarded to the call center where it is like working DX with QRM and QSB trying to understand the person on the other end. Yes, I own some junk radios, 991A, 450D, 746, Xeigu, and not one of those radios compares to a KX2 in functionality of RX. If you can't hear them you can't work them. My current radio for the past 5 years is the K3S with a second RX. I have worked thousands of QSOs on that radio. Nothing keeps its trade in value like an Elecraft. If a new ham can afford an Elecraft, you have not done him a disservice in recommending one to him. For a new ham, buying an Elecraft and putting up a resonant antenna is almost a guarantee for successful communication. Yes, I drank the koolaid, and I continue to do so. It tastes great. I want more. I guess that is why I ordered 2 K4s in group 1. 73, Morgan NJ8M BS + MS + $2.98 = COFFEE Real Life Experience = Priceless, says the man who set his back yard on fire with a breadboard tuner loading a 160 meter inverted L with 1000 watts.

For the past 10 years I?ve been using a 92 foot long doublet, up 45 feet, fed with home brew 600-ohm ladder line. From the back of my K-Line / KX3 / KX2 I ran about 10 feet of Belden 9913 coax out the window to this balun, under the eves. From there, 110 feet of that ladder line to the antenna. Worked really well but my radiation lobes were not going where I wanted them and I had limited support structures. So, the doublet came down this weekend and was replaced with a 40 / 30 meter Skeleton-sleeve dipole. That means this balun is excess to my needs. It is a Balun Designs model 4114T 4:1 dual-core current balun; rated at 5kW - I?ve never used more than 500 watts. It has an SO-239 coax connection on the unbalanced input and two studs with wing nuts on the output balanced side. It?s been mounted under the house eves all this time and has had very, very minimal exposure to rain. Some fading can be seen on the outside of the plastic housing, and a little black ?gunk? from liquid electrical tape got on a small part of it - all cosmetic. It is in excellent condition - I?ve never had a problem with it. Photos available upon request. If you are looking for a great, high power 4:1 current balun for your antenna farm - this one would be your choice. Take a look at the BalunDesigns.com web site for this model and it?s specs. You?ll see that it sells for $89.95 new plus shipping (and maybe tax). I?ll sell this one for $55 - free shipping to any USA address - Priority Mail. Contact me off-list if you have questions. Payment can be PayPal (w6jhb at mac.com ), cash, or personal check (one week to clear, please) Tnx & 73, Jim Bennett / W6JHB Folsom, CA From kevinr at coho.net Sat Jan 2 22:59:34 2021 From: kevinr at coho.net (kevinr) Date: Sat, 2 Jan 2021 19:59:34 -0800 Subject: [Elecraft] Elecraft CW Net Announcement Message-ID: <447602bb-0ada-8d41-0bfc-f6c2cc30e8fb@coho.net> Good Evening, ??

I am 67 years old, for 7 years I played WoW, for 6 years I played Everquest and for 5 years I have played Guild Wars 2. I enjoyed each of these games. I moved on to the more progressive game but still enjoy playing them from time to time. I only play GW2 at this time. Making the games set up and work with all peripherals is no harder than setting up FT8. Setting up RTTY with 2 or 3 decoders and getting everything to work...much harder. I am finding that many people in their 40s and 50s are getting into Amateur Radio. Some want the challenge of making stuff work, some want the antenna building experience, some want kit building but most seem to be from a subset of the population that are what one might call internet geeks. These guys do great in the transition to ham radio. Many gamers spend upwards to 2k$ on a video card only for their game box. So, $$$ is generally not a limiting option for this group. When they get hooked, they are hooked hard. In NCJ a few years ago, there was an article about contesting and video games. The parallels between the 2 of being "in the zone" were made. The same psychological high is involved but actually, it is more involved and dynamic than an online game. Pile ups, gotta love them, any mode you can get them, cw or ssb will provide that psychological high that melts the time away and keeps you on your toes. One can get so involved that you have to force yourself to take a deep breath and relax the shoulders and refocus on your posture so you can continue to run. 6, 7, 8, 9, 10 hours later, you have to pee, get a drink, grab a snack and get at it again. It is addicting. I am glad that cw contests are not every weekend because my life would end. LOL. SERIOUS online gaming requires raiding to really advance in MMORPG games. Serious ranking for WRTC takes the same. It takes tech, engineering, $$$ and commitment to advance in the world of contesting. What reward? Well, if you like to compete then this is your mojo. If you like to collect wallpaper for working all places, counties, countries, etc it is there. If you want to be recognised in a magazine for contest performance that is here. In the ham radio world there are no cash prizes. Not so in the gaming world, there really are professional gamers. Heh for that matter, I used to farm gold in games and sell it for $$$. I did this while waiting to Raid. In games you have dps meters and one always tried to be on the top of the pile by being best in your class for whatever your function was. N1MM has a rate meter and mults window based on band population and feedback and spotting networks. How does one get these gamers to transition to Amateur Radio? Good question. When I state that my hobby is Ham Radio, I get, "I did not think people did that now. Or Really, what is that? Why would you do that?" the conclusion that I get from these comments is: there is not enough exposure of the population to Amateur Radio. Plain and simple people just don't hear about it or see it in action. There are no public special events. There are not enough elmers to encourage people. There are no longer any towers being put up because of HOA and zoning ordinance rules. Towers used to be focal points for people to talk about. Why does he have a tower? Once that question was asked then a tour of the shack generally was involved and maybe 1 in 10 or 20 became interested to progress into the hobby. Rarely do you see a tower any more. Less exposure, less questions, about the hobby. People in general are curious. If we want Amateur Radio to survive, we as a whole have to whet that curiosity. We have to be Elmers. We have to welcome people and encourage them to get involved. We have to be honest about the realistic expectations of the hobby both in what it can and can not do, what is going to be the realistic cost to get going from marginal rig/station to contest capable station. The greatest disservice that is currently being done is licensing. I traveled for 23 years up and down the east coast. I have attended many radio club meetings and the focus has been licensing, getting more hams. Sadly, that is not the answer. Many of those that got the license never operated. Then there are the shack-on-the-crack 2 meter hams that just get on repeaters and yack all day long. The same 3 or 4 guys on the repeater day in and day out talking about the same thing. Heck if I were a new ham, I would give it up in short order and try to sell my baufong asap. The problem is even though we get people licensed there is little or No followup with helping them get on the air. When I got my license over 50 years ago, I studied the Ameco Radio theory course. I bought the ARRL handbook. That was my bible, my religion when I was 12 years old and living on the farm. Today you buy a license manual. It has all the questions and answers. Marking out all the wrong answers so that only the question and right answer appears and after reading just the question and the answer through 6 times and never reading anything else, there is a good chance that a person will pass the exam and never know a damned thing about radio but they will be an Extra. Whoopie. I expect a fire war when I say this and that is, most extra class hams licensed with in the last 15 years are dumber than a bag of hammers when it comes to radio theory, operation, station building, safe practices or anything as simple as soldering or crimping on a PL259. Much less do they know what an SO239 is and what it is used for. Then there are those that sell new hams broken or marginal radios and that despoils them on the hobby. There are tons of pitfalls to getting new hams into the hobby. The problem is not licensing, it is helping the peer get going so they can have fun. Whether it be CW, SSB, Contesting, Satellite work, building antennas or kits or just helping choose equipment and antennas and helping with that first QSO, those are the things we need to be doing. I have no proof of this, but, if a new ham does not get on HF quickly after getting licensed he or she will not be long for the hobby. Getting them invested in more than listening to a squelch tail is what needs to be done. I praise Elecraft in their business model. First and foremost, they do not produce crap radios. They are clean. They can be used in tough conditions. For the most part with reasonable care and feeding, they are bombproof. Plus, they have a price point for almost every entry into the HF spectrum of the hobby. Their KX2 is a marvel for mountain top operating or the traveling ham that wants a park-bench QSO in his down time. It is a quality radio under the 1k$ mark. Next is their KX3. It has a way better RX, extra bands and more power and sells well equipped for under 2K$. Then enter the K3S, now discontinued. It was the gold standard of all contest radios well equipped for Under 4k$. Now they have the K4 iterations which I believe will set a new standard for further manufacture of ham radios. In wondering if Eric and Wayne were gamers, they made a radio that can be upgraded by plugging in new cards which is congruent with upgrading a computer game machine. Because their focus has been quality before beauty, seemingly, they produce an excellent radio, which is durable and does not have the LS branding of chrome and fancy knobs to detract from lack of performance found in other brands. Any of their radios can be used to contest and they are not painful to use. Every time I have called Elecraft, I get someone who answers my questions. Honest, to the point answers and service beyond what any other manufacturer has today. I am not forwarded to the call center where it is like working DX with QRM and QSB trying to understand the person on the other end. Yes, I own some junk radios, 991A, 450D, 746, Xeigu, and not one of those radios compares to a KX2 in functionality of RX. If you can't hear them you can't work them. My current radio for the past 5 years is the K3S with a second RX. I have worked thousands of QSOs on that radio. Nothing keeps its trade in value like an Elecraft. If a new ham can afford an Elecraft, you have not done him a disservice in recommending one to him. For a new ham, buying an Elecraft and putting up a resonant antenna is almost a guarantee for successful communication. Yes, I drank the koolaid, and I continue to do so. It tastes great. I want more. I guess that is why I ordered 2 K4s in group 1. 73, Morgan NJ8M BS + MS + $2.98 = COFFEE Real Life Experience = Priceless, says the man who set his back yard on fire with a breadboard tuner loading a 160 meter inverted L with 1000 watts.

Never learned to solder anything. Theory was not my strength, and if you sat me in front of an Extra test, chances are better than even that I?d fail it. I mean a lot better than even. Like?OK, I?d fail it for sure. But I passed the 20 wpm three times, twice with 100% perfect copy for all five minutes. This skill, while handy in a pinch, doesn?t confer much more than bragging rights, whereas actually being good at the technical side would actually be dead useful. As opposed to, well, making me dead by some crazy accident. Still, and getting back to the age divide, I?d agree that if we?re focusing on the ability to talk to people anywhere in the world, we?re focusing on the wrong thing. Radio is magic? Yeah, closer, because it is, and I think we all of us who do this thing appreciate that. But I think the ARRL had the right idea when it started an initiative to court the so-called maker community, because there?s a lot of common ground there, harkening back to old traditions of home brewing (an aspect of the hobby on which I Feel I?ve sadly missed). Also, communication without infrastructure has a certain appeal, and I don?t think it gets enough press. Sure, we?ll use it if it?s there. But we don?t have to, and this is an aspect that definitely deserves more airplay than it gets. Add in competitive aspects to the no infrastructure. I think all of these things could appeal to younger people if presented right. On the other hand, I was a 14-year-old ham in 1987, and I had exactly zero success in getting much of anyone interested in this greatest of all hobbies, so that could mean I don?t have any idea what I?m talking about.

The best I can do is refer you to the K2ATOB instructions (download it). The 1st page lists all the associated updates. Download the instructions for each of those and inspect your K2 to see what has been installed. Also inspect your K2 to see which of the K2ATOB components have been installed. One big improvement that is not on that list is the IF crystals - you can purchase the matched set of 7 from Elecraft, or if you have the KSB2, use the matched set of 14. All those updates listed are available from Elecraft. 73, Don W3FPR On 1/3/2021 12:25 PM, Louandzip via Elecraft wrote: > Hey,??

I too, have patents and am a retired EE design engineer. I run three Elecraft rigs and two computers. But I admit that I feel dumber than a hammer when looking at all the software options and menu items. I haven't even considered a Flex because of my limited computer skills. Btw, at age 79, I can still build with SMDs. It's a matter of being blessed with good enough eyesight and steady hands. I got over looking down on others without my level of expertise when I realized there were just as many who have skills I don't have.

If you prefer not to add the jumper, plug stereo computer speakers into the headphone jack and plug your headphones into the headphone jack on the speaker. Try different computer speakers, some mute the speakers when headphones are plugged in, others do not. 73, Don W3FPR On 1/3/2021 12:58 PM, Chuck Chandler wrote: > I've recently begun volunteering aboard the museum ship USS Slater, where > they have a K2 in Radio Central.

I envy your photos on your QRZ page. My folks did not have cash for casual pictures. I do not have a pix of my BC348, ARC 5 or BC454 radios or the power supplies that I built to run them.Back then power supplies were basically finding an old boob tube and tearing it apart for transformer, rectifier tube, drilling out the riveted octal sockets and cleaning up the terminal strips. A combine knocked over a road sign and with some convincing from a hammer and angle iron vice with C clamps became the chassis for a few things. It takes quite a bit of wire cup brushing to get the red off the chassis. LOL. Later I got an Ameco transmitter, very similar to your transmitter in the pix. It was fun. I got my first pink slip running an EICO 720. I was CW on 40 and 599+ on 20 into the FCC monitoring station. I was 14 then. Everything at that time was a twin lead fed dipole with an L network made from surplus tuning units from old military equipment. I used a light bulb to tune the radio and the hum of the transformer and the brightness of the bulb and I was good to go. I remember working Malta on 15 meters during the winter. He was on AM and I was running CW to him. I was 13 then. Unfortunately, I do not have that QSL card. But I still have my first QSL card from WN9CNF. He used a magic marker on an index card and sent it to me. I worked tossing hay for cash and bought what stamps I could afford to send cards back. Today I love LOTW. I have never had a big DX station and never will. I am content to be a little pistol with a 38 foot tower and 2 elements on 20-10. A vertical for 40 and inverted L on 80 then end loaded with a 174 microhenry coil for a shortened 160 inverted L. All of this on a city lot with houses nearby. I love my Elecraft radios and Amp. I am looking forward to learning SO2R skills. Hopefully it will chase away alzheimers. Additionally, I am thinking about buying a welder to learn TIG welding. I just can't decide if i want to do aluminum or just everything else. AC or DC is the decision factor. But again, I ramble. BTW, I have done anesthesia for many electrophysiology labs for atrial ablation. I am now retired and your story brings back many many memories, again dangerous visions of the past. Keep well and strong, 73, Morgan NJ8M BS + MS + $2.98 = COFFEE Real Life Experience = Priceless, says the man who set his back yard on fire with a bread board tuner loading a 160 meter inverted L with 1000 watts.

So this is just FWIW: The (or at least much of the) allure of amateur radio lies in doing something yourself and seeing it actually work. >From DIY circuit design and construction to pruning the SWR out of a Vee in a tree to a strategy that nets a clean sweep in the SS, that satisfaction is universal, though possibly the more challenging the better. As a communications medium per se, radio is passe'. Let's not waste the energy fighting that. As a source of "Holy S, it works!", amateur radio has the potential to be as challenging and satisfying as any other. Maybe that's an attractant to sell.

I am an oddball tinkerer. I brew beer, make guitars, string beads, raise goats and make leather bound books, as well as fire up my radio from time to time. I was prepared to get my novice license in the early 1970?s. My parents said no. It was always in the back of my mind. I licensed a couple of years ago, got a KX2 and then started experimenting with anything that could be called an antenna, that is to say anything that conducts a current (from a lawn chair, to an umbrella, to hundreds of feet of abandon in-place power lines). Damn the theory, full speed ahead; all I needed was a match from the magical auto tuner. As a hobby, this one allows for tremendous diversity in what your interest in radio is with the same goal: tossing out a CQ and seeing who you get. Whether you build from scratch, buy off the shelf, rag chew, CQ or go digital, the goal is the same. Make a contact, meet someone you never have before, and enjoy it while you can. Who cares if one operator is an electronics dolt while another is a PhD EE? It is about contact, and Human contact in any form is precious. I simply like the challenge of making contacts with antennas, in the opinion of the more learned, ?that won?t work.? I have been told to ?Read the antenna book? because my experiments are ?illogical.? I guess I have to delete the contact I made using a chicken wire antenna? Let?s all remember that Maxwell, Marconi, Hertz, Popov, Bose, Hughes and Fr. Roberto Landell de Moura did not have the internet or the Antenna Book. They had each other. Just my foul smelling overly verbose opinion on the matter.

I've done it and enjoyed it, but I didn't learn much from it.? The fault comes in pretending that experimenting without understanding is better than, or at least equivalent to, actually spending the effort to understand what you're doing.? Trying something ... anything ... is fun, but too many hams seem to want to use it to justify ignorance.? All of those people you mention may not have had the Antenna Book, but they did have the writings of each other and I guarantee that they used them ... which is exactly what the Antenna Book is since it was written by other hams who took the trouble to understand what they were doing so that you at least had the opportunity to do so as well. Nobody says that you have to take advantage of that, but it does mean that you're just choosing the fun of playing with stuff you don't understand very well ... like somebody who just mixes different chemicals to see what happens.? And yes, I've done that as well. Dave??

Message-ID: I have a K3... the best radio I've ever owed in my 50+ year ham life. I'm currently using a US Interface Navigator with it for digital modes. This is now sold as the Time Wave Navigator and has worked really well for me for many years. My understanding is that the K3S and now the incoming K4's have sound cards built-in via the USB port. So perhaps I won't need the Navigator anymore when my K4 eventually arrives. But my question is whether there is still something to be gained using a newer transceiver interface with the K3S or K4? I've been looking at the Microkeyer III with its 24 bit audio processing. Does anyone have any hands-on experience with the Microkeyer III with Elecraft radios? I'm particularly interested if it has a lower noise floor or other features that might not be found in the stock K3S or K4.

Looks like I have some research and studying to do. https://la3za.blogspot.com/p/la3za-unofficial-guide-to-elecraft-k2.html I was marginally aware of some of the updates, but what spurred my interest was stumbling upon an Elecraft page for the K60XV option which listed a number of prerequisites I don't have and wasn't aware of.? The page doesn't look current (second bullet says no CW on 60m) and I haven't found the option as being available on the website.? I'm not greatly interested in 60m with my K2...is was just one of those rabbit holes I stumbled into. https://elecraft.com/pages/k60xv-upgrade-information https://ftp.elecraft.com/K2/Manuals%20Downloads/E740069%20K60XV%20man%20rev%20B.pdf Anyway, my K2 is working FB for my purposes so is not in desperate need of fixes or improvements.?

I could use some email magic. Yes, T-Bird does all that and more. It is far more stable and secure, and includes provisions for Dual-Key Encryption in current versions. It even has a routine to transfer your file structure and address book from Outlook into T-Bird "hands-free". Totally customizable. I've been using it ever since I switched from IBM OS/2 to Windows almost 15 years ago. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From lists at subich.com Mon Jan 4 10:04:47 2021 From: lists at subich.com (Joe Subich, W4TV) Date: Mon, 4 Jan 2021 10:04:47 -0500 Subject: [Elecraft] Long messages In-Reply-To: <942055847.4202212.1609767483387@mail.yahoo.com> References: <1609765791785-0.post@n2.nabble.com> <942055847.4202212.1609767483387@mail.yahoo.com> Message-ID: <2bef9e08-01e4-4e04-ada2-a70bd2d7ef46@subich.com> On 2021-01-04 8:38 AM, Louandzip via Elecraft wrote: > That would def be my preference. 20 years ago, everything was > reflectors, but Elecraft is the only one I'm dealing with now.

A competent e-mail program like Thunderbird or Outlook will take care of all those issues, provide the advantages of a "forum", allow the user to download the messages in bulk then work (read/respond) offline (e.g. on an airplane, in areas where WiFi/LTE/5G are not available) and upload responses in bulk when connectivity is available. Competent e-mail software does wonders to maximize signal to noise ratio - even with a "forum" - although it can't eliminate the "Sent to all" generated flame wars that are unfortunately more common with forum based groups than properly configured e-mail lists. 73, ...

I have to disagree with you. As much as I 1) LOVE forums, and 2) loathe every additional email I don't want/need, for amateur radio related subjects, like Elecraft (I'm in this one and 4 other related on two platforms), I do not think a forum is the way to go. I'm busy, and I don't even GO to most of the forums I spent years on anymore because.... well, I am busy.? The "push" nature of a reflector allows me to review quickly and stay right up to date on all the subject areas I am interested in. Now, that is NOT to say the "reflector" idea cannot be improved upon. I PREFER Groups.io, which is kind of a hybrid of sorts.? If you want, it's JUST a reflector.? BUT, it ALSO provides a searchable database, and a LOT of other tools for use when you need to research historical threads and posts. Now, I know lots of folks resist change and Groups.io is a change.? But it works "better" for a wider range of folks, and IMO is much easier to administer. Finally, IF we are not to move to Groups.io, then I would like to see us return to the basic "rules" we USED to observe before.... 1) Only quote what is absolutely necessary to keep thread continuity. 2) Strip away everything from the "____________________" and down. 3) Observing the quiet death of threads when they drift and/or sufficiently beat the horse to death. In the past, Eric was the arbiter of the "rules".? That is a TERRIBLE use of his time.? Perhaps if we could hammer out some rules that Wayne and Eric would "sign-off" upon, and then find a couple of Reflector moderators from among the more experienced, level-headed, and thick-skinned, et al. of us to fulfill the lion's share of the admin duties (with Eric and Wayne ONLY managing by exception), we MIGHT just streamline the reflector traffic a bit. That's my 2/100ths of a fiat currency "dollar".? And worth both pennies.? 73 and God Bless and Keep every single one of you! ______________________ Clay Autery, KY5G (318) 518-1389 On 01/04/21 07:09, Barry wrote: > Just another reason why a forum makes so much more sense than pushing out > emails to everyone. > > Barry W2UP > > > > -- > Sent from: http://elecraft.365791.n2.nabble.com/ > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to ky5g at montac.com From oldmanshu at icloud.com Mon Jan 4 11:33:14 2021 From: oldmanshu at icloud.com (Joseph Shuman) Date: Mon, 4 Jan 2021 11:33:14 -0500 Subject: [Elecraft] Long messages Message-ID: <4E386808-9FAE-43C8-AD33-B692DF07E176@icloud.com> OK NZ8P From dave at nk7z.net Mon Jan 4 11:48:33 2021 From: dave at nk7z.net (Dave Cole) Date: Mon, 4 Jan 2021 08:48:33 -0800 Subject: [Elecraft] Long messages In-Reply-To: <4677d8d4-0d90-563e-9c73-5068e6083c7e@montac.com> References: <1609765791785-0.post@n2.nabble.com> <4677d8d4-0d90-563e-9c73-5068e6083c7e@montac.com> Message-ID: <8e9a413f-ec0a-ae43-3bd0-91f6e46b16ba@nk7z.net> Say it isn't so... 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst.

In addition to Don's response, you may want to look at this: https://www.w8fgu.com/pics/k2faob/w3fpr_K2%20audio%20Fix.pdf http://www.w3fpr.com/download_files/FP-CB%20mounting%20photos.pdf I have done this, using a piece of perfboard. To avoid shorts, in my case the PCB is in a piece of heat shrink tube. If you want a kit, check out https://www.w8fgu.com/k2_fixedaudio.html Instead of perfboarding it, I should have bought a kit from Dave, but sending a parcel by mail to PA0 would need me to mortgage my house, not to mention a lot of patience (another PCB ordered recently was stuck for *nine months* in Chicago). The advantage is that the 2nd output is fixed audio volume, so you can adjust the speaker audio and the headset audio separately. In my case (connecting multiple headsets on the speaker output) this approach has another advantage: I added audio sidetone to my K2 so that the people using headphones can hear eachother speak, yet the fixed-audio output doesn't have this, so there is no feedback from the speaker. When you use a speaker, make sure you use one that works well for SSB audio. For visitors, I would consider making some headsets available instead. SSB-via-speaker is more difficult to decode, SSB-via-speaker for people without SSB ears will just result in "there was a guy playing radio noise" at the exhibition. 73, Geert Jan PE1HZG From mickchall at yahoo.co.uk Mon Jan 4 14:07:33 2021 From: mickchall at yahoo.co.uk (Mick Hall) Date: Mon, 4 Jan 2021 19:07:33 +0000 (UTC) Subject: [Elecraft] Nifty Manuals References: <955826407.10899443.1609787253180.ref@mail.yahoo.com> Message-ID: <955826407.10899443.1609787253180@mail.yahoo.com> These are still available new in the UK at Elecraft K2 Plus Options Nifty Mini Manual | | | | | | | | | | | Elecraft K2 Plus Options Nifty Mini Manual Compact K2 Mini-manual.

That is the *WRONG WAY* to connect a K3, P3 and Computer. Connect the RS-232 plug from microHAM USB III to the "PC" jack on the P3. Connect the XCVR jack on the P3 to the RS232 jack on the K3.

My guess is that your antenna is parallel to the house wiring, and is inducing a current on the ground or neutral wire. A replacement AFCI breaker might fix the problem. Or a heavy choke on the AC. This may or may not be your situation. Most newer houses run all electric wires from the breaker box up into the attic and back down to wherever they need to be. At least in single-story homes. That puts the attic antenna close to the unshielded house wiring. In my house, it wasn't the AFCI that would go nuts, but the doorbell would ring when I went over 35 Watts on 20m. I had to install a choke on the doorbell wire to stop that. Now, every time I transmit, I imagine the doorbell or smoke detector going off in my neighbor's 2-story next to me. jon N0WL On Mon, Jan 4, 2021 at 2:32 PM Tom Doligalski via Elecraft < elecraft at mailman.qth.net> wrote: > Should have mentioned that there up is no trouble at 25 watts. > > Certainly no trouble at 100 watts back at Field Day. > > Sent from my iPad > > > On Jan 4, 2021, at 12:57 PM, Tom Doligalski wrote: > > > > ?Over the last several weeks I?ve been having problems with the arc > fault detector (AFCI) in my fusebox.This does not control the power to the > shack, but to our garage door operners. > > > > It seemed random at first, but I think I?ve tracked it down a bit. > > > > Running an Elecraft K3/KPA500/KAT500 combo.

I have no insight into the roadmap for most amateur digital software. However, I doubt that many developers will expend the effort to do 24 bit processing. The 97 dB (theoretical) - 88 to 90 dB practical dynamic range of a well designed sound card is quite adequate for most HF purposes. The "background noise" in suburban/semi rural areas is on the order of -135 dBm (~0.05 uV). That means a 90 dB dynamic range can handle from the background noise to about S9+30 dB. Using an attenuator or reducing the RF gain in the presence of signals above S9+20 dB can extend the useful dynamic range by another 20 dB or more. The only use case for greater dynamic range would be for SDR purposes where a very wide spectrum was being processed simultaneously or for extremely "quiet" frequencies (e.g. VHF/UHF with antennas pointed to a quiet part of the sky - EME or radio astronomy). In the VHF/UHF case, dynamic range (noise floor) can be improved much more economically through the use of low noise preamplifiers (and receiving converters). 73, ...

In-Reply-To: Message-ID: In an ideal world, we would not have any analog audio in use for digital modes. Analog RF to the ADC in the front end of the radio. Digital through the "radio" to the digital path to the computer to the digital processing for digital modes. The K3S actually goes through a DtoA conversion and then a AtoD again within the radio. Does the K4 also do this? For audio, of course, somewhere we need to do DtoA conversion. 73 Bill AE6JV On 1/4/21 at 8:36 PM, n6kr at elecraft.com (Wayne Burdick) wrote: >The sound card is built into the K4 (stereo line out for RX, >line in for TX).

I've used it on AFSK but not yet on other digital modes. Level setting is via soft controls, not dedicated physical knobs. This requires tapping the touch-screen several times, then turning the main tuning knob to adjust each level. You might want to download the available *Introduction to the Elecraft K4* or the *Builtin Operating Manual* files at https://elecraft.com/pages/manuals-downloads. Click Support, then Manuals, then K4 and you'll see it. Setting up the K4 for RTTY using its internal sound card required no additional cables beyond what I was already using for computer control (a USB A-B cable). YMMV, though, and if you want dedicated level knobs, you can connect an external sound card through analog 1/8" LINE IN/OUT phone jacks. You will still need to use the soft controls to tell K4 which type of connection you're using. 73, /Rick N6XI On Mon, Jan 4, 2021 at 5:12 PM Dennis Dinga wrote: > This question keeps coming up but, but the answers are either > incomplete or confusing.

In-Reply-To: <20210105011215.C0E39149AA51@mail.qsl.net> References: <20210105011215.C0E39149AA51@mail.qsl.net> Message-ID: <06cf01d6e31c$387ec5b0$a97c5110$@w0yk.com> There are multiple aspects to this question. As another K4 field tester, here's my take, trying to objectively outline the choices for all users. 1. Any of the following soundcard alternatives can be used with the K4: a. PC soundcard, either integrated or added, e.g., via USB or plug-in card to a desktop b. USB ham radio "interface" box, e.g., RigBlaster, microHAM microKeyer or SO2R controller c. K4 internal soundcard In all cases, the Windows Sound Control has level controls for all these alternatives. In addition, the b and c alternatives have their own level controls that can be thought of as logically in "series" with the Windows level controls. Generally, the Windows level controls are set to result in a "reasonable" range of control by the additional level controls of alternatives b and c. In the case of alternative b, there are often physical knobs. The K4 (alternative c) has on-screen level controls that can be varied with on-screen up/down arrows or by using the VFO-A knob. 2. All of these alternatives are equally adequate performance-wise. The exception might be low-end soundcards in alternative a. Another exception might be minimizing A-D and D-A conversions, in which case the K4 soundcard, c, is ideal. There are no analog audio cables, or signals, between the radio's digital audio and the PC application, pure K4 digital audio direct to the software. 3. Choosing one of the above alternatives is a personal preference we all get to make. If you like physical knobs readily available, then the alternative b is good. If, like me, you prefer simplicity and seldom touch the soundcard levels, then the minimalist K4 soundcard solution c is nice. If you have need for other features, e.g., SO2R control, then you'll have that alternative b anyway and will use its sound card and user interface. Each of us can consider the alternatives and decide which is appealing and suits our operating needs best. I suspect it boils down to choosing between alternatives b and c. 73, Ed W0YK -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Dennis Dinga Sent: 04 January, 2021 17:11 To: elecraft at mailman.qth.net Subject: [Elecraft] Does a K4 need an external sound card for FT8? This question keeps coming up but, but the answers are either incomplete or confusing. Courtney KD6X asked it again on Jan 3 and has not received an answer. Here's the way I'd like to ask it: I use a West Mountain RIGblaster advantage instead of the sound card in my computer. Why? So that I have the convenience of adjusting TX and RX levels with physical knobs instead of using sliders on a monitor. So how do you set levels with the K4? Does it require fiddling with menus and going through several steps? And like Courtney asked, is there anything else to gained by using an external 24 bit card? -Dennis N6DD ++++++++++++++++++ Here is the way that Courtney KD6X put it: "Any value in using a Microkeyer III with a K3S or K4D? I have a K3... the best radio I've ever owed in my 50+ year ham life. I'm currently using a US Interface Navigator with it for digital modes. This is now sold as the Time Wave Navigator and has worked really well for me for many years. My understanding is that the K3S and now the incoming K4's have sound cards built-in via the USB port. So perhaps I won't need the Navigator anymore when my K4 eventually arrives. But my question is whether there is still something to be gained using a newer transceiver interface with the K3S or K4? I've been looking at the Microkeyer III with its 24 bit audio processing. Does anyone have any hands-on experience with the Microkeyer III with Elecraft radios? I'm particularly interested if it has a lower noise floor or other features that might not be found in the stock K3S or K4.

It is not a matter of a faulty detector and a HF caused false AFCI trip. There is no way 100W RF to trip a detector that is OK at 500W. Tom guessed it right, it should be the KPA3-100. As the issue is on 80M only (maybe on 160M too?) and the other bands are OK, the DC circuits (as the power supply connector) can be ruled out. It could be a faulty choke or a capacitor causing a LF parasitic oscillations. Actually the arc fault detector is watching for LF waves that every arc use to emit. Remember where the radio started from. 73, Val LZ1VB ----- ????? ?? Tom Doligalski via Elecraft (elecraft at mailman.qth.net), ?? 04.01.2021 ? 19:57 ----- Over the last several weeks I?ve been having problems with the arc fault detector (AFCI) in my fusebox.This does not control the power to the shack, but to our garage door operners. It seemed random at first, but I think I?ve tracked it down a bit. Running an Elecraft K3/KPA500/KAT500 combo. The AFCI ONLY trips when on 80 CW, running 100 watts (the KPA500 in standby bode). If the KPA500 is ON (running 500 watts) there is no problem. Seems fine on other bands?. 80M antenna is a Carolina Windom. The usual baluns/line isolator/grounding stuff. Any ides? Kinda worried that there is an issue with the 100 W amp in the K3. 73.

It has pushed the IC7300 out the door for the best bang for the buck place. What I was most interested in was the phase noise of the radio. It is minimally down to at least -148db. That is where the 7300 falls flat on its face. Additionally, so does Yaesu 450D and 991A. Those 2 radios are one radio shack radios. I know this because I own both of them. $1700, what a great price point to recommend a new ham that wants a contest grade radio that he can build upon. Seemingly, based on the Sherwood stats, the FTDX10 would work well in a 2 radio environment. That would beg the question, would they be ideal for an SO2R setup. $3400 for 2 radios and add a $100 to $300 dollar controller and you are GTG. WOW! Granted the radios do have many shortcomings when it comes to a full contest grade radio but for the most part they, could be an excellent choice. The problem with field day is that tons of people have Ic7300s and they are a disaster at FD. The FTDX10 should solve all those problems being low on phase noise. Maybe our FD ops will be much easier and if the rigs were FTDX10s. We shall see. Where the FTDX10 falls flat is in a few areas that can be worked around. The areas that they are deficient are, one antenna port, no rx antenna port, nonstandard plugs for ALC and PTT lines for an amp and other associated station accessories, such as amps, sequencers, etc, and ofcourse, no diversity receive capability. My all time hate is the RJ45 connector for microphone input. And, I don't believe it can do dual watch. It is either VFO A or B not both. This is what I can gather from the literature in the trade brochure. All except, dual rx and diversity can be worked around. At this price point this is an excellent box. It is about the same size as a current K3S but a bit shorter in height. There is an optional CW filter/narrow banpass filter of 300 hz but I have no idea the steepness of the cut off for that filter. Plus there is an adjustable rise time feature that allows the user to produce an undesirable cw signal. This is one of the big negatives that Yaesu incorporates into their radios. Same size as a K3S, built in Pan, Video out, 3 usb ports, SD card for DVR recording providing record on fly and 5 memory bands, 5 built in CW memory slots, optional outboard keypad to key DVR and CW memory banks, with all of these features, this now is the best bang for the buck and the rx surpasses the K3S spex plus the DNR and filtering is astounding in Yaesu radios. Heh, even the cheapest 450D DNR function can eliminate 40 meter alternator noise in my F150 when I run mobile. It is even better in this radio, most likely, because it is generations better and an SDR. It weighs 13 pounds, did I say DXpedition or travels well. That is yet to be seen. Some of the main mechanics of the main tuning and bezel knobs might cause some worry. Time will tell. The radio is made on a cast aluminum frame much the same as the 991A. My 991A has been abused, mobile, salt water ops, special events, FD, camping, portable from picnic table...still works great. I have used it on FT8 for days at a time running 80 watts. No problems. Now that I am retired and home, the 991A has been relegated to 2/440 operation only. I just might sell it and raise money for my new FD radio, the FTDX10. The real issue with this radio is, the K3S used prices might just have dropped another $500. The K3S is nearing the EOL time and the replacement with better RX stats and a pan adaptor included with no extra cabling or boxes fitting into the same size as a K3/K3S for Less than 1/3 of for the most part what a a full K3S/P3 with video out would cost. Yes you would be missing a few features but for the most part, Yaesu has hit it out of the park with the FTDX10. Have I turned the dial on one, put a set of cans on my head, operated CW on one, in a word No. I might end up driving to Ohio to take a listen to one at DXengineering, if they are open (post Covid 19) and see what all the hubbub is about. Dollars and cents wise, almost 3 FTDX10s can be had for the price of one K4 base model. As with all Yaesu and Icom products, the first offering is to recoup R&D, and what the market will bare. My guess is that it will stabilize just as the 991A did, which was initially MSRP $1999, I am thinking down to what it is now, $1199. So that would within a year, put this radio dropping to compete with the 7300 at about $1200 for the Yaesu. Even right now, I would choose the FTDX10 over the Yaesu, hands down. It is just a far better radio. I'm wondering when Elecraft is going to come out with a mid market radio like perhaps a...KX4?

LOL ---------- Forwarded message --------- From: Morgan Bailey Date: Wed, Jul 29, 2020 at 3:55 PM Subject: K4 To: K8TE , I have a few dollars short of $10,000 on deposit to Elecraft for 2, K4 radios. I am in the first group. I am looking forward to getting them going here in my shack. I am building an SO2R station and fully realize the challenge in doing so. VA6AM triplexers for 160/80/40 and 20/15/10 and the associated band pass filters and a 2x8 hamation switch to control all antennas to either radio. Are already in place. Triplexers and Bandpass filters don't work with high SWR, or atleast, they don't work very long. My antennas are simple. Now that I have retired. I put up a 38 foot tower (Rohn 45G bracket to the house) with a Navassa 5+6mtr beam and for 160/80/40 I use a vertical for 40 with a 160/80 inverted L all fed with the same coax. The 160/80 L is actually a full sized inverted L 33 feet up and 33 feet out then at the end is a 174 microhenry coil that stops 80meters but inductively loads 160. It gives me 2:1 for 30khz on 160. On a city lot, that is pretty good. It has to be, because that is all I can do without wonky interaction between the antennas. All of my antennas are cut for the CW portions of the band. I don't work much SSB. The beam, JK Navassa5 gives full band coverage under 1.5:1 on all bands, warc included. Is this a great contest station in the middle of a city, not by a long shot. I am getting too old to be a tower monkey to manage guy wires and correct tensioning that is needed in Kansas with the huge temp variation. My tower is simple and is good enough. I do well enough. It keeps me happy. Much of the time I only compete against myself. I have read your QRZ page and all the self accolades, in a word, Impressive. Providing for my family and helping them grow into good citizens has been a rewarding life for me and my wife of 43 years. One of my sons is a ham, NS0R. Both of us enjoy CW. I will never be able to do such as you have as my work career did not permit it. I traveled for the last 20+ years providing relief anesthesia in major trauma centers from Alaska to Maine and down to North Carolina and almost everything in between. I have joined many ham clubs over the years and mostly Elmered new hams setting up antennas, station building to include safety, grounding and ergonomics. Having lived in a hotel room for nearly 3 decades, I transformed them into a combination Makers Den vs Mad Bomber decoration with all the wire, coils, EMT boxes, Aluminum, Fiberglass Spider beam poles, etc. Making EFHW, Fan Dipoles and Parallel wire dipoles in the long halls of a hotel at 3 AM provided me with a way to help others get on the air. I still do it. How many antennas that I have built, given away and installed at various QTHs, I have no idea.I regularly get calls from hams who have questions from NY to KS to Maine. How many hours I have spent on other peoples towers either building them or installing beams and other antennas, I have no idea. Having run curves with all my antennas on a RigExpert 230, and saving them for comparison has enabled me to problem solve regarding antenna interaction. Knowing what I know from empirical testing over the years and having seen many great Ozone Generators AKA: antenna tuners, I always seek to optimise antennas for the band segment that I have chosen to work. I have seen people use tuners and flash over the lightning surge protector and burn out a gas discharge tube all because of high SWR. Knowing that one can get away with terrible antennas at low power and SWR of 15:1 matched to 1:1 is a workable solution for operation with low power, because QRP works. The problem that I address in my posts is make the best of your station. No antenna does everything. No antenna is 100% efficient. I stress making the best antenna possible for operating. Because most new hams and some financially taxed hams dont have the money to spend on the hobby, I have always tried to provide an antenna that will work without a tuner as much as possible, thus saving money for the new op. In doing so, baluns don't blow up, RFI is kept to a minimum. Enjoyment is experienced because of simple functionality and not having to deal with RFI problems such as those experienced when the RF gets into the shack computer during a contest will be realized. My point being, if anyone who is going to drop $5K on a K4 station, they should spend another $200 on fabrication to make the radio a performer to its optimum. If you have deep pockets buy a Tashian 70 foot positive up positive down, tilt over that will hold 50 sq ft wind load and enjoy. If $20,000 to $30,000 is not in your budget then at least build a decent antenna system, be it a vertical, EFHW, Fan dipole, parallel wire dipole, or put up fiberglass masts to hoist up wires or dipoles to radiate as best possible. Just buying a 6BTV and installing it over 60 25 foot radials, will work miracles. 73, Morgan Bailey NJ8M From ted.roycraft at gmail.com Tue Jan 5 11:47:40 2021 From: ted.roycraft at gmail.com (Ted Roycraft) Date: Tue, 5 Jan 2021 11:47:40 -0500 Subject: [Elecraft] Anticipation !!

LOL ---------- Forwarded message --------- From: Morgan Bailey Date: Wed, Jul 29, 2020 at 3:55 PM Subject: K4 To: K8TE , I have a few dollars short of $10,000 on deposit to Elecraft for 2, K4 radios. I am in the first group. I am looking forward to getting them going here in my shack. I am building an SO2R station and fully realize the challenge in doing so. VA6AM triplexers for 160/80/40 and 20/15/10 and the associated band pass filters and a 2x8 hamation switch to control all antennas to either radio. Are already in place. Triplexers and Bandpass filters don't work with high SWR, or atleast, they don't work very long. My antennas are simple. Now that I have retired. I put up a 38 foot tower (Rohn 45G bracket to the house) with a Navassa 5+6mtr beam and for 160/80/40 I use a vertical for 40 with a 160/80 inverted L all fed with the same coax. The 160/80 L is actually a full sized inverted L 33 feet up and 33 feet out then at the end is a 174 microhenry coil that stops 80meters but inductively loads 160. It gives me 2:1 for 30khz on 160. On a city lot, that is pretty good. It has to be, because that is all I can do without wonky interaction between the antennas. All of my antennas are cut for the CW portions of the band. I don't work much SSB. The beam, JK Navassa5 gives full band coverage under 1.5:1 on all bands, warc included. Is this a great contest station in the middle of a city, not by a long shot. I am getting too old to be a tower monkey to manage guy wires and correct tensioning that is needed in Kansas with the huge temp variation. My tower is simple and is good enough. I do well enough. It keeps me happy. Much of the time I only compete against myself. I have read your QRZ page and all the self accolades, in a word, Impressive. Providing for my family and helping them grow into good citizens has been a rewarding life for me and my wife of 43 years. One of my sons is a ham, NS0R. Both of us enjoy CW. I will never be able to do such as you have as my work career did not permit it. I traveled for the last 20+ years providing relief anesthesia in major trauma centers from Alaska to Maine and down to North Carolina and almost everything in between. I have joined many ham clubs over the years and mostly Elmered new hams setting up antennas, station building to include safety, grounding and ergonomics. Having lived in a hotel room for nearly 3 decades, I transformed them into a combination Makers Den vs Mad Bomber decoration with all the wire, coils, EMT boxes, Aluminum, Fiberglass Spider beam poles, etc. Making EFHW, Fan Dipoles and Parallel wire dipoles in the long halls of a hotel at 3 AM provided me with a way to help others get on the air. I still do it. How many antennas that I have built, given away and installed at various QTHs, I have no idea.I regularly get calls from hams who have questions from NY to KS to Maine. How many hours I have spent on other peoples towers either building them or installing beams and other antennas, I have no idea. Having run curves with all my antennas on a RigExpert 230, and saving them for comparison has enabled me to problem solve regarding antenna interaction. Knowing what I know from empirical testing over the years and having seen many great Ozone Generators AKA: antenna tuners, I always seek to optimise antennas for the band segment that I have chosen to work. I have seen people use tuners and flash over the lightning surge protector and burn out a gas discharge tube all because of high SWR. Knowing that one can get away with terrible antennas at low power and SWR of 15:1 matched to 1:1 is a workable solution for operation with low power, because QRP works. The problem that I address in my posts is make the best of your station. No antenna does everything. No antenna is 100% efficient. I stress making the best antenna possible for operating. Because most new hams and some financially taxed hams dont have the money to spend on the hobby, I have always tried to provide an antenna that will work without a tuner as much as possible, thus saving money for the new op. In doing so, baluns don't blow up, RFI is kept to a minimum. Enjoyment is experienced because of simple functionality and not having to deal with RFI problems such as those experienced when the RF gets into the shack computer during a contest will be realized. My point being, if anyone who is going to drop $5K on a K4 station, they should spend another $200 on fabrication to make the radio a performer to its optimum. If you have deep pockets buy a Tashian 70 foot positive up positive down, tilt over that will hold 50 sq ft wind load and enjoy. If $20,000 to $30,000 is not in your budget then at least build a decent antenna system, be it a vertical, EFHW, Fan dipole, parallel wire dipole, or put up fiberglass masts to hoist up wires or dipoles to radiate as best possible. Just buying a 6BTV and installing it over 60 25 foot radials, will work miracles. 73, Morgan Bailey NJ8M From hb9cvq at hispeed.ch Tue Jan 5 12:25:12 2021 From: hb9cvq at hispeed.ch (hb9cvq at hispeed.ch) Date: Tue, 5 Jan 2021 18:25:12 +0100 Subject: [Elecraft] Yaesu FT DX10 In-Reply-To: References: Message-ID: <006101d6e387$b971ee70$2c55cb50$@hispeed.ch> I (HF CW/SSB) own a FTDX101MP and disagree with the FTDX101D assessment , John. Using here my YAESU now all the time for 6month. I can state it is mostly even (DSP!, very small TX PWR overshoot) better than my K3S-P3. Elecraft pros: QSK is much better in K3S. K3S has good diversity , you can record QSOs, RX 1 and RX2 are accessible independently , Main Ant (RX) out does exists. These features are inferior in YAESU or simply missing.

I am not sure this is true but hope so and of course then hope that the kit is coming out sooner rather than later. I have a deposit down for the second group of shipments and this would mean that I might actually see the K4 sooner. Once the K4D with superhet frontend is available, the new front end will be ordered plus a second K4D. I already have homes for my two K3 radios. Probably will also want another KPA 1500. So any word on CE approval process, whether it is required for kits sold into the EU and the availability of the kit version of the K4 is anxiously awaited. As and aside it would be nice if the next version of the KPA 1500 could be run efficiently at 400W. Contest power is generally 1500 Watts in EI but normal output power is limited to 400W. An Acom 2000A also in the shack may be the amp to use when operating under normal conditions. Having said this, the KPA is a beautiful amp and it is for that reason a second one is considered. Yes perhaps this is greed but at 76 there are not that many more sunspot cycles in store for me. I started like most of you with a surplus RGB II (forerunner of the HQ120) bought from summer job and baby siting. The first rig was an old borrowed TCS surplus radio before building a two 6146 rig from a QST article. What a great hobby radio is. 73 Doug EI2CN From gthornton at thorntonmostullaw.com Tue Jan 5 14:46:50 2021 From: gthornton at thorntonmostullaw.com (George Thornton) Date: Tue, 5 Jan 2021 19:46:50 +0000 Subject: [Elecraft] Sherwood Receiver report K4 ?

The only thing I'll take exception is that I suspect his estimates of noise levels are wildly optimistic, which further supports his observations about sound card dynamic range. From where I sit with neighbors running WSJT-X modes on the same band, I look at dynamic range differently. Consider a local who's 50 dB over S9 on a well calibrated S-meter (yes, that's optimistic too). If you accept 5 dB/S-unit (I don't), your lower limit is an S2 signal, or S1 at 6dB/S-unit. Few hams have noise levels below S5. Depending on band and the direction my antennas are listening, my noise level in the Santa Cruz Mountains with nearest neighbors ~400 ft from my antennas is S1-S2 with my 6M optimally aimed (to the North Pole) to reduce noise and S4-5 pointed at either two solar systems in those closer houses. While still in a Chicago residentail neighborhood, it was a very good day if I got below S6 on HF on very inferior antennas. You've got to be in the middle of NOWHERE with a 50dB over S9 neighbor to need more than a 16-bit sound card. What you DO want is a much better than average sound card, which is why I've looked to the better units designed for the semi-pro audio market. One of the qualities of A/D and D/A stages important both to audio pros and to hams is their amplitude linearity around their noise floor (and very quiet audio stage feeding the A/D converter. There's also the issue of how the units address differing sample rates.WSJT-X works at 16-bits, 48 kHz. If the hardware runs at 96 or 192 kHz, how good are they at the conversion. And so on. 73, Jim K9YC On 1/4/2021 5:36 PM, Joe Subich, W4TV wrote: > >> Are you aware of any move afoot to support higher bit levels in > > upcoming versions of popular software? > > I have no insight into the roadmap for most amateur digital software. > However, I doubt that many developers will expend the effort to do > 24 bit processing.?

And that assumes the 50 dB over S9 signal is within the receiver passband.? Otherwise the receiver AGC will increase the volume of the weak signal to the point where sound card dynamic range is totally not an issue. However, as Jim mentions on his web site, it is important to set audio levels so as not to over-drive the sound card input.? And apparently with some software it is important to set the sound card to the correct sample rate.

Windows sets the hardware to operate at what is defined as the "Default Format" and accepts that sample rate, bits, channels (e.g., "2 channel, 16 bit, 48000 Hz (DVD quality)"). When an application opens the sound card for input with different parameters the operating system does the up/down sampling leaving the original data stream available for other applications (the ability of multiple applications/instances to operate in parallel). The "easiest" (most accurate) conversion is when the sample rates are integer multiples (e.g., 8000, 12000, 16000, 32000, 48000 Hz). The least accurate conversions are where the sample rates are non-integer multiples (e.g. 44100 Hz, 11025 Hz an 48000 Hz.). Generally, bit depth conversions are "integer multiples" but there is considerable loss of linearity (at the low end) when downsampling from 24 bit to 16 bit or 16 bit to 8 bit, etc. 73, ...

I noticed that during SKCC events I don?t have the issue. In the following??contest instead of using internal keyer though serial port I switched to an external keyer and sure enough the issue did not surface. That brought me to a serial port cable that was provided by the previous owner of the K2. I found that the cable was just a standard serial extension cable. I quickly made a makeshift serial per Elecraft recommendation and was not able reproduce the problem with the correct cable. I ran the K2 in Winter RAC and it worked as intended. I am happy that I did not fry a chip with the wrong cable but apparently wrong cabling may introduce a quite strange side effect that makes the chip work incorrectly when it is under the temperature pressure. 73, Arkady/NU6N From turnbull at net1.ie Wed Jan 6 03:25:34 2021 From: turnbull at net1.ie (turnbull) Date: Wed, 06 Jan 2021 08:25:34 +0000 Subject: [Elecraft] K4 Kit and CE In-Reply-To: Message-ID: <5ff57404.1c69fb81.c4e8d.646a@mx.google.com> Bill, I stand corrected.? ?

Since it's available on the "internet wayback machine" (thanks Dave), at least we all can find what was originally published. I'm running a wget process with some flags to make a copy for myself. Sometimes trying to get the original web domain transferred is more expensive and not worth the trouble with whomever he was using (the website was hosted out of Germany per netcraft.com). Then there's the IP concerns and family wishes if any. All great information, glad it's still available via archives at least. I found it in early December right before it disappeared when I went to go look up something. I now have both the paper K3 and PDF K3S books to enjoy for a while :) Don't mind spending around $35-40 each for a quality manual that I can read offline.

Its a kit and while I didn?t build one I have been using a prototype that Jim Veatch (designer) lent me.

I have run the mW calibration procedures and the K3s and the Q5 are operating fine together. I have set the K3s max XVTR power output to 1.00 mw on each band (XVn PWR L 1.00) and I expected to be able to turn the power all the way down to .01 mW as stated in the manual. However, the lowest I can get the power turned down to with the PWR knob is .10 mW. I need to be able to turn the K3s xvrt power output down very low to drive the xvtr to about 500 mW output to match the low drive requirements of one of my brick amps. I can set the XVn PWR to a drive level below .10 mW but the power knob does not seem to be operable below .10 mW. The power settings for each xvtr band in the XVn PWR setting are showing this same behavior. Reference page 41, Using Transverters, XVn Power, "L .01- L 1.27 specifies a power level in milliwatts." Reference page 68, Xvn PWR Default L .01 Any help with what I'm missing here is truly appreciated. 73, Jack W4NF From scott.small at gmail.com Wed Jan 6 22:13:37 2021 From: scott.small at gmail.com (Tox) Date: Wed, 6 Jan 2021 19:13:37 -0800 Subject: [Elecraft] KE7X Website Expired In-Reply-To: <069372a4-1b8e-9cf8-8acf-7f4756988c8d@montac.com> References: <2183f7a1-1223-6fc7-bb92-4e538bdbd259@gmail.com> <925C1F66-7EDD-4305-A46D-A555E0B86183@bellsouth.net> <069372a4-1b8e-9cf8-8acf-7f4756988c8d@montac.com> Message-ID: For some reason, GMail won't let me attach it.

Fred was a friend, as he was to many of us. He had family in Denver, where I live, and visited often. We got together whenever our calendars both allowed. Fred and I and Gus, KB0YH, had lunch together, and spoke with him after his health took the turn, just days before he passed away, here in Denver. I was one of his assistants - more accurately, one of his students - in doing the book on macro programming. Working with him was more than a pleasure. The best person to contact, I suggest, would be Vic, VE3YT. Vic was a close friend of Fred's and co-author on more than one of his books. Revitalizing his website would be a benefit to the entire Elecraft community and a fitting memorial to Fred.

I successfully used standard top-tuning caps placed on the PC board bottom (which is mounted up-side down, so becomes the upper side of the board). I measured the clearance as being about 2mm between the upper part of the caps and the shield of the KPA100.

The MJF unit works if you can adequately pick up the noise through the receive antenna. I made a video of it that I put on youtube, but the video actually turned out pretty poorly because you just can't hear the noise I was demonstrating eliminating in the video. Oh well. When I originally put this in, I was using it to eliminate both a rogue plasma tv and also the neighbor's pool pump. Both of the offending devices have since been replaced so I don't use the MFJ 1026 as much, but it's definitely a nice tool to have in the box. I have kicked around the idea of putting up an active receive antenna for it but am concerned that I won't be able to place that antenna far enough away from my regular HF antenna with legal limit usage. I've always thought that this type of functionality could be built into the K3/K4 since it already has a separate RX input. Maybe Elecraft would consider it in a future OS upgrade feature for the K4?

You can google it, or go to http://www.kk5jy.net/LoG/ for the details. I have one, completely out of sight in the front yard under my gravel and it really works. I have a noisy neighborhood (yes my home is noisy too, but I have mitigated as much of that as I can for now) and this antenna makes radio a lot easier to enjoy. Far less noise and despite low S meter readings, signals pop out clear and easier to copy. Some like to use a preamp with this antenna?I prefer it without but that?s a matter of personal preference. It worked surprisingly well for me, and for a few other hams I know of who have tried it. It?s worth a look... 73, David - N5DCH > On Jan 7, 2021, at 5:15 PM, Tim Tucker wrote: > > I have one and also have a small horizontal receiving loop around the > perimeter of the property with the intended purpose of picking noise > generated by the neighbors' stuff.

If you have more than one source of RFI, not so good... If the source is distributed, not so good... Needs to be specular in nature for best results. I have had better luck with an ANC-4, as opposed to the MFJ-1026. I have a set of articles on RFI location and suppression here: https://www.nk7z.net/category/info/rfi-mitigation/ That will give you the list of all RFI related articles on my site. 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst.

In my experience it runs perfectly and is a joy to use. There is only one difference between using Apple Silicon and any other Mac. My setup is: KX3 Base configuration M1 Macbook Apple thunderbolt to USB cable Standard Elecraft USB cable for the KX3 Sabrent Sound Card dongle Anker self powered USB hub WSJT-X 2.2.2 for the Mac as downloaded from the WSJT website. The only unusual requirement is that the instructions for changing the memory size given in the software instructions will not work for M1 Macs. Instead you use the following commands in the terminal: sudo sysctl -w kern.sysv.shmmax=104857600 sudo sysctl -w kern.sysv.shmall=25600 The command sysctl -a | grep sysv.shm will verify that the change is made. At the moment the above must be done on each reboot. That's it, otherwise it works just as it does on an Intel Mac. I have my serial port set for 38,400 baud, 8,2,none and am running full CAT control with rig split enabled. It appears as of today, January 7, that the Fldigi folks are still working on a version that will work on Apple Silicon. In my testing the latest standard Mac version would not load.

If so, add the Alternate AF Gain Wiring mod. While you are doing that, I recommend that you replace the AF Gain control. The easiest way to change the control is to cut the pins close to the body, then alternately heat the two mounting tabs while rocking the pot to remove the control. Remove the pins one at a time, clean up with solder wick and if solder remains in the holes, push it out with a wooden toothpick. 73, Don W3FPR On 1/11/2021 11:54 AM, dl7le wrote: > Hello Yls and Oms.I have a problem with my K2.

In-Reply-To: References: Message-ID: Martin, I have not done it, but the major problem I see is the question of "how to get the signal inside the enclosure". There is precious little room on the rear panel. You could go through the right side panel depending on how you locate the oscillator with respect to the transverter. 73, Don W3FPR On 1/11/2021 5:10 PM, Martin wrote: > Elecrafters, > i have a GPS-controlled LO 116MHz i would like to feed to the XV144 2m > external Transverter.

If that does not work, it could be an unstable power supply issue (0,5A ~12V required). Otherwise I suppose there is a loose connection inside of the P3. You could check the cable from the main board to the display. The manual has a section about replacing the display with useful pictures (fig 25&26). 73 Gernot DF5RF Am 11.01.2021 um 23:46 schrieb Ken Widelitz: > P3 stopped working.

I think that being hooked to the guts of the processor in the K3 was a killer -no amount of fiddling would calm it down. Was "usable" at 100 watts but my 80 meter antenna runs across roof about 15 feet above my shack and it would go berserk on 80 at 1500 .I ended up buying BCD to serial boards from UNIFIED MICROSYSTEMS they are opitcally coupled and just take the BCD out of the K3 - They also sell hi side relay driver board as well - https://www.unifiedmicro.com/decoder.html In my case I put both boards inside the control box for my Array Solutions Ratpack 6 antenna switch.

I think that being hooked to the guts of the processor in the K3 was a killer -no amount of fiddling would calm it down.

Since it's in my shack, I just reload the firmware and go on. It seems to occur most often after a power outage on the 240 VAC line though I've seen it occur with normal turn-on/off and (very infrequently) while just sitting there idle. My power supply is normally always on and the amp powers up via the +12 Volt sense driven by the K3. A couple of guys at Elecraft were working with me (before Covid) to resolve this problem but we never determined anything. I think they believed I was making this stuff up. It only happens every few weeks so is not a major annoyance but I surely would like to have it resolved. Incidentally, I normally run the amp via KPA1500 Remote connected via ethernet and seldom touch the front panel. The K3 is on a very heavy duty UPS so it never powers off except via it's front panel.

I had forgotten that the REM input is fed from the K3 12V output, and that is what turns the amp on. If that input is at 12V when applying 240V, you go into firmware load. So a slight mystery remains, as reported by others, that this sometimes occurs for no apparent reason, at times when we?re "pretty sure" the 240V is already on. When dead-starting and turning on the 240V, I always wait a few sec before turning on the K3 remotely. But sometimes it comes up in firmware load anyway. Thankfully this is always recoverable. FYI: You can also turn on a KPA1500 or 500 by pulsing a line in the Aux bus via a K3 macro. Info on this is on p. 21 of the K3 Remote Owner's Manual.

It allows me control and monitoring of the amp (meters, power on/off, op/standby, ant 1/2) from any web browser, including smartphones with two factor authentication.

I had forgotten that the REM input is fed from the K3 12V output, and that is what turns the amp on. If that input is at 12V when applying 240V, you go into firmware load. So a slight mystery remains, as reported by others, that this sometimes occurs for no apparent reason, at times when we?re "pretty sure" the 240V is already on. When dead-starting and turning on the 240V, I always wait a few sec before turning on the K3 remotely. But sometimes it comes up in firmware load anyway. Thankfully this is always recoverable. FYI: You can also turn on a KPA1500 or 500 by pulsing a line in the Aux bus via a K3 macro. Info on this is on p. 21 of the K3 Remote Owner's Manual.

Do you have anything connected to the KPA1500 REM RCA connector? 73 de Dick, K6KR >>On Jan 12, 2021, at 11:16, Gary Johnson wrote: ?We have a K3 and KPA1500 at a remote site. The KPA has 240V applied to it all the time, and actually turns on with the K3 via the Aux Bus. We use the remote control application via Ethernet. Works great. Occasionally, the amp won?t turn on, and when we investigate, it?s in the firmware load state. The KPA1500 Utility is then able to reload it via USB, and we?re operational again. Nothing on the computer should be accessing its USB port to cause it to go into that state. I have noticed that if we cycle the 240V power, sometimes that will put it in firmware load as well. Is there a common cause here? -Gary NA6O ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to rocketnj at gmail.com From pe1hzg at xs4all.nl Wed Jan 13 09:24:05 2021 From: pe1hzg at xs4all.nl (Geert Jan de Groot) Date: Wed, 13 Jan 2021 15:24:05 +0100 Subject: [Elecraft] KRC2 In-Reply-To: References: Message-ID: <2d5d4e85-3cbd-ffa5-ab12-9a079e97d49c@xs4all.nl> > Tom - I will give you some unsolicited advice- Another point of consideration is that the KRC2 is programmable, but the programming code is old and doesn't run on today's platforms.

(and will be in a random state). You don't have enough power for a successful Tune. Try running the TX gain calibration with the K3 Utility. Or, with a dummy load, ATU in BYP, make sure TUN PWR is at "nor", then set pwr to 5.0 watts exactly and long press XMIT to send a carrier for several seconds. (That will do a manual tx gain cal on that freq). Then engage ATU and do an ATU TUNE and it should find a match. If the TX gain cal fails, something is wrong with the LPA. Keith WE6R Elecraft Tech.

I bought the Antlion boom mic which uses a small earth magnet cemented to the head phones to mount the boom mic. I don't use the mic very much in the shack, but the headphone hang on a coat hook by my radio cabinet for frequent use. Boom mic is intended for outdoor use in portable operation with my KX3. I tested the mic on air with my K3 and got good reports with it. I also got a Senheiser noise-cancelling headphone but were not as comfortable as my Bose QC-2 (which I use mainly on aircraft). I gave the Senheiser to my wife. I tried the Yamaha with boom mic but they caused my hearing aids to oscillate (howl) whenever I put them on (so I sold it). Get a good quality stereo headphone that are comfortable (over the ear muffs for better noise isolation). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From augie.hansen at comcast.net Thu Jan 14 12:13:20 2021 From: augie.hansen at comcast.net (Augie "Gus" Hansen) Date: Thu, 14 Jan 2021 10:13:20 -0700 Subject: [Elecraft] K4HD Availability Schedule In-Reply-To: <20210114114126.15701149A9A3@mail.qsl.net> References: <1129549082.1651199.1610581800630@mail.yahoo.com> <6AFE1BB6-E1B1-48DD-8DD0-862C519CC8C4@gmail.com> <1163645357.1871629.1610595107125@mail.yahoo.com> <20210114114126.15701149A9A3@mail.qsl.net> Message-ID: <2bf5e415-cc29-64aa-8d33-45debd85d873@comcast.net> On 1/14/2021 4:39 AM, Rich NE1EE wrote: > ... > Note the time is listed as "Register for our K4 Webinar on January 22 and 5:00 PST" > but I suspect PDT.

If there's a PC in the shack with an unused Ethernet port, one that connects to the Internet via WiFi, Windows Internet Connection sharing could also work, with an Ethernet cable between PC and K4. Per WA6HHQ, Elecraft is also working to provide a way to update the firmware via flash drive, where a PC (or MAC?) could be used to download firmware from a web site. Obviously updating via direct Internet connection will be the most convenient. 73, Bob, N6TV From eubage at icloud.com Fri Jan 15 12:25:38 2021 From: eubage at icloud.com (Eugen Bauknecht) Date: Fri, 15 Jan 2021 18:25:38 +0100 Subject: [Elecraft] tip of 3.5 mm plug remains in key jack Message-ID: <5CE9ABD8-066B-4B66-9C48-620DA4AC5779@icloud.com> Hello, after removing the cable of an external key the tip of the stereo 3.5 mm plug remains in the KX2 key jack.

I think the reason in my case was 1) the quality adapter (Sony) was designed for newer jacks, and 2) the older Kenwood jack is very "strong". That is, the spring tension of the clips that hold the 1/4" plug exert a lot of pressure. I assume that is because in days of old (I picked this up decades ago, and still have an original headset from those days) the plug was also pretty sturdy. Think old style switchboards, and cycles. I ended up using a variety of tools, and going in from the rear. The broken tip was rotated, so it would not simply pop out. I needed to use a fine round steel pick to line it up correctly, then use another fine tool to press the tip out from the rear. I went to all this trouble because to get at the jack on the 830 means dismantling much of the radio. I originally thought, that's too much work, I should be able to do this easily. Not so. Much patience, finding the right tools, dexterity. Not familiar with the KX2, but assume that it would be easier because the KX2 is much newer tech. Heck, might not even be worth the effort, if the jack is reasonably accessible...just replace it? Or is it board-mounted? Even so, prob easier to get at than my 830. OTOH, the 830 jack is "open", so I could get at the internals. Some newer jacks are encased. In that case (sic), I think that a replacement is in order. ~R~ 72/73 de Rich NE1EE The Dusty Key On the banks of the Piscataqua From weaverwf at usermail.com Fri Jan 15 13:12:36 2021 From: weaverwf at usermail.com (weaverwf at usermail.com) Date: Fri, 15 Jan 2021 13:12:36 -0500 Subject: [Elecraft] Activity on the Elecraft reflector In-Reply-To: References: Message-ID: <5E48DFB8-DFB4-4EAF-8819-D89CD201BD9E@usermail.com> I have no authority but I?d say you are fine here.

I don't mean to belittle the problem, but it's the same as when the flexible part of my hearing aid (earbud) broke off in my ear canal - use the proper tools and work *very* gently. If the diameter was larger I would recommend a tool set used for screw extraction but I don't think that you could find one for that size that outside of a dental office. The suggestion of using a small drill bit and pin vise sounds like a reasonable thing to try. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From ardrhi at gmail.com Fri Jan 15 19:09:16 2021 From: ardrhi at gmail.com (Gwen Patton) Date: Fri, 15 Jan 2021 19:09:16 -0500 Subject: [Elecraft] tip of 3.5 mm plug remains in key jack In-Reply-To: References: <20210115175446.BB0EC149ACB2@mail.qsl.net> Message-ID: I had to do this, too, on my KX3.

They are really helpful. Here is what I have learned. Several options how to remove the tip of the plug from the jack: A. use a ball pen refill with a proper inner diameter, i.e from a BIC pen, which pulls over the tip firmly and then out the tip B. put a small piece of super glue on the tip of a straightened paper clip, insert it, wait sufficient time for perfect binding, then pull out the tip. Glue gel should work better than glue fluid. Avoid putting the glue at the inside of the jack. You may use a straw around the clip for shielding. C. use a drill with appr. 1mm or 0.04 inch diameter, drill by hand into the tip and pull it out. D. use a screw with a small diameter und carefully screw it in the tip and pull it out. E. open the rig and use a lock pick or similar tool to push the broken tip out from the back of the jack. It only works if the jack is open from the behind. F. bring the rig to an Elecraft authorized repair service/repair center ..tbc Finally, option C worked for me.

For almost 30 years, I've served on international Standards Working Groups (of the Audio Engineering Society Standards Committee) with representatives of the world's two manufacturers of quality audio connectors, Switchcraft (US) and Neutrik (EU). In our meetings, both have recounted problems they have with counterfeit versions of connectors produced in China. I'm also a member of the Working Group on Microphones, and major mic manufacturers have long had the same problem with their products. Among the defects of the counterfeit connectors are 1) lousy construction, so that they fall apart and 2) they don't conform to the physical size definitions of the Standard for the part they claim to be. As long as 20 years ago, I was reading about counterfeit fasteners causing problems for aircraft manufacturers. 73, Jim K9YC From w3ab at w3ab.org Sat Jan 16 15:59:36 2021 From: w3ab at w3ab.org (W3AB) Date: Sat, 16 Jan 2021 12:59:36 -0800 Subject: [Elecraft] Headphones In-Reply-To: References: Message-ID: The Sony phones are great.

False economy. Yes. I own a spectrum analyzer and scope from a company that I'm told ripped off designs from a major US mfr outsourcing to China, and costing me 20-25% of what I would have paid for the US mfr's product.

Unfortunately the version that's at the manual link right now is an older one. That will be corrected by tomorrow, and you can download it. I could send you the document directly, if you'd like. It's too big to post to a list. Check out page 40. Some specs are different from the K3; the radios have two entirely different architectures. The K4 adds a large color screen/panadapter, external monitor/keyboard/mouse support, ethernet connectivity, more digital I/O, more receive antenna selections, dual receive standard, and virtually unlimited future expansion capability. 73, Wayne N6KR > On Jan 17, 2021, at 6:18 PM, BRUCE WW8II wrote: > > When is Elecraft going to publish some preliminary specs like sensitivity, > and noise floor??

The idea is that when you turn the radio off, all the things that are subject to damage are protected by disconnecting them from the external world and shorting their inputs to ground. This approach probably wouldn't protect against a direct hit to one of the wires coming into the radio, which are most likely on the antenna input and the power from a solar system. But I understand that the most significant part of the problem is voltage spikes introduced when the external wires act as antennas and pick up nearby lightning strikes. I'm not a hardware engineer, so I'm going to assume that relays are used in this device. Some of the things I see this device doing are: USB connection: Elecraft tells us that blown USB chips are one of the more common forms of lightning damage in the K3. There are 4 wires in the USB interface, two of which carry power from the external world. The relay(s) would float the USB wires and ground the connections to the internal USB chip. Since power from the external world is present when the radio is off, we can't ground the power leads, although we can ground the power input to the radio's USB chip. Note that currently a computer attached to the K3 can see its USB chip, even when the radio is turned off. This change would mean that the computer would no longer see the radio over USB, which might have annoying software effects. A similar thing could happen to the antenna inputs. Key/Paddle, microphone, headphones, RS232, etc. would be treated the same way. The AUXbus would be treated similarly, but anything that can be turned on via the AUXbus would need special handling. The 12V power input is needed to turn the radio on with the power button. I don't know how often radios are damaged through their 12V power input. This input may not need protection. Otherwise, the relay that protects power and the switch to the radio could be the only things powered when the radio is off. If it can't be protected, it could be made easily field replaceable. It would be neat if there's enough room inside a K4 to put this kind of protection "under the covers". 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | The race is not always to the swift, nor the | (408)348-7900 | battle to the strong, but that's the way to bet. | www.pwpconsult.com | - Damon Runyon | From rmcgraw at blomand.net Sun Jan 17 22:39:34 2021 From: rmcgraw at blomand.net (Bob McGraw) Date: Sun, 17 Jan 2021 21:39:34 -0600 Subject: [Elecraft] Waaay OT: A new kind of QRM to be aware of ..., warning issued by FCC today Message-ID: <7cb50da4-53f5-f618-d69a-4e02aced1044@blomand.net> Also be advised that the ARRL Volunteer Program has been asked by the FCC to monitor ham frequencies and report "interesting" conversations. 73 Bob, K4TAX Message: 5 Date: Sun, 17 Jan 2021 13:07:41 -0800 From: Wayne Burdick To: Elecraft Reflector Subject: [Elecraft] Waaay OT: A new kind of QRM to be aware of ... warning issued by FCC today Message-ID:<46466485-35AB-4F79-A982-2730EE0B6400 at elecraft.com> Content-Type: text/plain; charset=us-ascii The FCC just posted this: https://www.fcc.gov/document/amateur-personal-radio-users-reminded-not-use-radios-crimes I guess this isn't surprising, considering current events.

Surge Limiters / Filtering / Shielding / System Layout with minimizing coupling effects are part of this. Protection against any threat level ( EMI energy / current / voltage /EM field derivatives) can/should realistically and economically not be implemented just finally at the radio itself. Lightning is first of all a more external system problem (Tower / Station Single Entry Panel Point / Cable- Layout, loop, spark over voltage / conductor melting/welding...).

The most important thing we can do to minimize lightning damage is to seriously implement proper grounding and bonding in our stations and throughout our homes. N0AX's ARRL Book on the topic is a great reference; I collaborated with him on it. Also study the slides for talks I've done at west coast hamfests. Don't let the word "audio" in the link fool you. This is about EVERY element of grounding and bonding specifically for ham radio. http://k9yc.com/GroundingAndAudio.pdf Another VERY important thing is to NEVER use shunt mode (MOV) type surge protectors anywhere except at the Service Entrance (where power enters the building). MOVs are more likely to CAUSE destructive failure than to prevent it. Surge-X, Brick Wall, and a third company whose name I've forgotten make series-mode surge protectors. They're more expensive, but a LOT cheaper than our radios. There's a brief discussion of series-mode vs shunt mode beginning on page 28 of this link http://k9yc.com/SurgeXPowerGround.pdf A far more extensive discussion begins with slide #69 in this link. It's by Andy Benton, a very good engineer who designed the Surge-X products. This is the first part of a 4-hour talk that Andy and I did at conventions for companies designing and installing professional audio and video systems in public buildings and for corporate operations. http://k9yc.com/InfoComm-PowerSystems2012.pdf My good friend Bill is right on about very high currents and voltages being induced on wiring inside our homes. In addition to antennas, lightning comes in on power lines, telephone lines, and CATV lines. Finally, I want to emphasize what I said at the start about doing this VERY seriously. Lightning has a way of finding things we didn't do. 73, Jim K9YC On 1/17/2021 9:19 PM, hb9cvq at hispeed.ch wrote: > I think we need to divide protection into different topologies/ barriers/ > zones.

That QRM, more and more often, also bleeds over into other places it doesn?t belong, like what should be apolitical reflectors. It seems there is no longer anywhere we can get away from someone or some group airing their grievances wherever they are at the slightest provocation.

If the group owners, (Elecraft), wanted things tighter, they would moderate more tightly. If they don't have staff to moderate, then they should not worry when things get off topic, which for the most part they don't, or close the group. This style of moderation allows folks to push the limits for short periods of time, between moderation events, which is why we get posts about everything else. The longer the time period between moderation events, the further topics drift. This method of moderation almost guarantees topic drift. I would LOVE to see just Elecraft information here, and nothing else... But not my group, so I just delete most non-Elecraft posts. 73, and thanks, Dave (NK7Z) https://www.nk7z.net On 1/18/21 6:48 AM, Grant Youngman wrote: > I?m not at all surprised the FCC felt it necessary to make the statement they did.

Do not think for one minute that one can provide lightning protection inside the equipment or structure. Any and all driven ground rods and systems MUST be bonded back to the AC Mains ground.?? This is per NEC.?? Many hams violate this rule and actually create a condition where equipment WILL BE damaged by a near-by lightning strike.? This occurs by not bonding the station ground to the AC Mains ground outside of the house. Hence by this not being done, there are 2 or more ground points with resistance between the points and the path of current is through ones equipment regardless, if antennas are grounded, disconnected, and the equipment is turned off. 73 Bob, K4TAX Message: 4 Date: Sun, 17 Jan 2021 22:33:47 -0500 From: Bill Frantz To: Elecraft Reflector Subject: [Elecraft] Automatic lightning protection for radios, an off the wall idea Message-ID: Content-Type: text/plain; charset=UTF-8; format=flowed I've been thinking about some kind of automatic lightning protection for radios, specifically ones like the K3 and K4. The idea is that when you turn the radio off, all the things that are subject to damage are protected by disconnecting them from the external world and shorting their inputs to ground. This approach probably wouldn't protect against a direct hit to one of the wires coming into the radio, which are most likely on the antenna input and the power from a solar system. But I understand that the most significant part of the problem is voltage spikes introduced when the external wires act as antennas and pick up nearby lightning strikes. I'm not a hardware engineer, so I'm going to assume that relays are used in this device. Some of the things I see this device doing are: USB connection: Elecraft tells us that blown USB chips are one of the more common forms of lightning damage in the K3. There are 4 wires in the USB interface, two of which carry power from the external world. The relay(s) would float the USB wires and ground the connections to the internal USB chip. Since power from the external world is present when the radio is off, we can't ground the power leads, although we can ground the power input to the radio's USB chip. Note that currently a computer attached to the K3 can see its USB chip, even when the radio is turned off. This change would mean that the computer would no longer see the radio over USB, which might have annoying software effects. A similar thing could happen to the antenna inputs. Key/Paddle, microphone, headphones, RS232, etc. would be treated the same way. The AUXbus would be treated similarly, but anything that can be turned on via the AUXbus would need special handling. The 12V power input is needed to turn the radio on with the power button. I don't know how often radios are damaged through their 12V power input. This input may not need protection. Otherwise, the relay that protects power and the switch to the radio could be the only things powered when the radio is off. If it can't be protected, it could be made easily field replaceable. It would be neat if there's enough room inside a K4 to put this kind of protection "under the covers". 73 Bill AE6JV -- This email has been checked for viruses by AVG. https://www.avg.com From n6kr at elecraft.com Mon Jan 18 11:44:06 2021 From: n6kr at elecraft.com (Wayne Burdick) Date: Mon, 18 Jan 2021 08:44:06 -0800 Subject: [Elecraft] K4 introduction manual link updated In-Reply-To: <1610980002095-0.post@n2.nabble.com> References: <06E07D0A-8792-4572-B641-8C6119A6768C@elecraft.com> <1610980002095-0.post@n2.nabble.com> Message-ID: <10F2A495-5499-4168-A5CE-1FE7AB933C1A@elecraft.com> Our "Introduction to the Elecraft K4" manual link has been updated to revision B4.

I don't see how to do this disconnect outside the building. When I consider a direct strike on my shack's lighting rods, I see massive currents flowing down the thick aluminum cables from the rods to the grounding system. I see these currents inducing currents in any wires in the house, including the USB cable. The lightning rods are the first level of protection, but may not be enough to protect sensitive electronic equipment. Remember, when we work on these radios, we have a grounding wrist strap and a conductive mat on the work surface etc. 73 Bill AE6JV On 1/18/21 at 11:38 AM, rmcgraw at blomand.net (Bob McGraw) wrote: >Just remember that ALL lightning protection must be >accomplished outside of the house or structure.?

There were 3 of them, and every one was loose on the ground rod. They all appeared to be regulation listed connectors, but poorly installed. Glad I was there to find that. Electrical wiring, including grounding, was a mess at the home we bought in NorCal in 2006. I found multiple mis-wired outlets, including several in a laundry room/half kitchen fed by phase (hot) and ground from the 240V circuit for the adjacent dryer. That was in a garage/apartment which now houses my shack; power enters the house, and is fed to a breaker panel in the second building. The house had no ground at all -- a #10-#12 (painted) bare copper wiring ran from the service entrance panel to an outlet for a garden hose, which was fed by PVC pipe. The ground for the panel in the second building wandered from the panel up to and through the attic crawl space to the other side of the building, then run neatly down the outside wall next to the facings for windows to a ground rod. It was the only ground for the entire system. 73, Jim K9YC From dennis at mail4life.net Mon Jan 18 13:30:36 2021 From: dennis at mail4life.net (Dennis Moore) Date: Mon, 18 Jan 2021 10:30:36 -0800 Subject: [Elecraft] Subject: Waaay OT: A new kind of QRM to be aware of ... warning issued by FCC today In-Reply-To: References: Message-ID: <340d1605-a720-acb6-a39a-06ddc8d8f2f2@mail4life.net> Hear, hear. 73, Dennis NJ6G On 1/18/2021 06:10, Steve Hall wrote: > During my hamming of over 50 years, the FCC has never felt it necessary to > threaten hams not to break the law, that is not until we have this new > administration coming into control.

The idea is that when you turn the radio off, all the things that are subject to damage are protected by disconnecting them from the external world and shorting their inputs to ground. This approach probably wouldn't protect against a direct hit to one of the wires coming into the radio, which are most likely on the antenna input and the power from a solar system. But I understand that the most significant part of the problem is voltage spikes introduced when the external wires act as antennas and pick up nearby lightning strikes. I'm not a hardware engineer, so I'm going to assume that relays are used in this device. Some of the things I see this device doing are: USB connection: Elecraft tells us that blown USB chips are one of the more common forms of lightning damage in the K3. There are 4 wires in the USB interface, two of which carry power from the external world. The relay(s) would float the USB wires and ground the connections to the internal USB chip. Since power from the external world is present when the radio is off, we can't ground the power leads, although we can ground the power input to the radio's USB chip. Note that currently a computer attached to the K3 can see its USB chip, even when the radio is turned off. This change would mean that the computer would no longer see the radio over USB, which might have annoying software effects. A similar thing could happen to the antenna inputs. Key/Paddle, microphone, headphones, RS232, etc. would be treated the same way. The AUXbus would be treated similarly, but anything that can be turned on via the AUXbus would need special handling. The 12V power input is needed to turn the radio on with the power button. I don't know how often radios are damaged through their 12V power input. This input may not need protection. Otherwise, the relay that protects power and the switch to the radio could be the only things powered when the radio is off. If it can't be protected, it could be made easily field replaceable. It would be neat if there's enough room inside a K4 to put this kind of protection "under the covers". 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | The race is not always to the swift, nor the | (408)348-7900 | battle to the strong, but that's the way to bet. | www.pwpconsult.com | - Damon Runyon | ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to charles.hardt at mgccc.edu From hb9cvq at hispeed.ch Mon Jan 18 14:53:32 2021 From: hb9cvq at hispeed.ch (hb9cvq at hispeed.ch) Date: Mon, 18 Jan 2021 20:53:32 +0100 Subject: [Elecraft] Automatic lightning protection for radios, .... an off the wall idea In-Reply-To: References: Message-ID: <006301d6edd3$99a04c30$cce0e490$@hispeed.ch> Yes, Jim, but: "It's also the kind of destructive failure that the use of MOV surge protectors can CAUSE". MOV can be used even in AC power applications (50/60Hz) , but only if the potential thermal run away effect ( drawing more leakage current after energy absorption/exposure or by aging ) is controlled by a series connected high impedance (no-fire mode) spark gap. What is however critical under non-fire RF conditions (MOV -ZnO has big nF capacitance and is a semiconductor) is the nonlinear diode effect. This can lead to RF rectification (harmonics, emission issue) before the firing level is reached. 73 Andy HB9CVQ -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Jim Brown Sent: Montag, 18.

For a while, the FCC declined to take action against criminal (like "convicted") violators if the crime did not involve telecommunications law. I don't remember the actual case that Doug mentioned other than it wasn't one of mine :) but I do remember that there have been several. For other violators, there is a provision in the Communications Act that requires the FCC to determine if the conviction bears on the moral qualifications to become or remain an FCC license holder, and there are provisions in other statutes that bar someone from holding or receiving a license if in arrears to court-mandated payments.. As far as the present situation, what the notice said (in plain language) is using a radio while planning or committing a crime is a crime itself. Has nothing to do with the content as long as it does not involve planning or committing that criminal act. Yes, there are limits to First-Amendment-protected speech.

The problems include 1) where they dump the current when they short out a strike; 2) accumulation of discharge current over time degrades their performance, causing them to fail shorted or open; and 3) they can start a fire! When an MOV shorts the strike to the equipment ground ("green wire") it raises the chassis potential of connected equipment; when that equipment is connected to other equipment by "low voltage" wiring (audio or video cables, Ethernet or other computer cables) to equipment plugged into different outlets (or even a different MOV device), the potential difference between the two pieces of gear is likely to fry I/O circuitry. Many years ago, we in the world of pro audio learned this, with equipment for large audio (that sometimes included video systems) spread out over wide areas. As long ago as the '90s, very well-educated EEs recounted stories of computers in their design offices networked by wired Ethernet being fried by lightning induced on the Ethernet cables and computers with MOV surge protectors. No intentional antennas involved (not hams). All of this is a great reason for using WiFi rather than wired Ethernet unless the added latency of WiFi cannot be tolerated (remote operation, for example). I dumped the use of wired Ethernet a couple of years before moving from Chicago in 2006. Decent WiFi hardware provides plenty of bandwidth for my uses, including streaming audio and hi-res streamed compressed video. 73, Jim K9YC From w3tb.ted at gmail.com Mon Jan 18 17:57:07 2021 From: w3tb.ted at gmail.com (Ted Edwards W3TB) Date: Mon, 18 Jan 2021 16:57:07 -0600 Subject: [Elecraft] Subject: Waaay OT: A new kind of QRM to be aware of ... warning issued by FCC today In-Reply-To: <7ce3c7d7-74c3-1f11-56c6-2d3721904ba4@subich.com> References: <225b38fd-95a9-32ec-eed3-7022cf15fbe6@kanafi.org> <7ce3c7d7-74c3-1f11-56c6-2d3721904ba4@subich.com> Message-ID: When I was in college during anti-war protests about 50 years ago, protesters tried to pressure me to use the college station to coordinate with other colleges.

For a 3/4" copper tubing loop 3 ft in diameter, at 14 MHz, I come up with: Antenna efficiency: 38% (-4.2 dB below 100%) Antenna bandwidth: 31.5 kHz Tuning Capacitance: 85 pF Capacitor voltage: 2,445 volts RMS Resonant circulating current: 18.2 A Radiation resistance: 0.058 ohms Loss Resistance: 0.093 ohms Inductance: 1.53 microhenrys Inductive Reactance: 134 ohms Quality Factor (Q): 445 Distributed capacity: 8 pF TX power was arbitrarily set at 100 W.? The conductivity of Cu is about 59E10 Se vs 38E10 Se for Al and I once saw an analysis that showed silver soldering lengths of copper pipe and 45 deg fittings into an octagon raised the loss by about 20 % @ 14 MHz.? The best configuration seems to be a continuous copper strip [wider is better within reason].? There will be some additional loss in the connection to the capacitor.? Since the radiation resistance is in the tens of milliohms range, this is a case where antenna DX wax might actually work.? I have an Alexloop I use with my K2.? It works, sort of, best on 20 and up.? One caveat to any small mag loop:? They are essentially resonant transformers and the operative word is "resonant."? Any ATU must be bypassed and the loop tuned exactly to resonance [R+j0X].? The swr is a function of the area ratio between the large loop and the small driven loop.? Letting the ATU "find the match" results in a very good approximation to a dummy load. The above calcs came from www.66pacific.com/calculators/small-transmitting-loop-antenna-calculator.aspx which I like, there are a number of others out there.? I distrust the BW number, my Alexloop has about 60% of the calculated value before it assumes the shape of a dummy load. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/18/2021 2:05 PM, Alan Bloom wrote: > MFJ makes a pair of small, remotely-tuned loop antennas, the MFJ-1786 > that covers 10-30 MHz and the MFJ-1788 that covers 7 to 21+ MHz.

The housing does not protect the capacitors that are in house made and bugs can crawl into the housing and short them out. Secondly, the plastic housing in Kansas will be destroyed by the sun. The best thing about the loop is the loop itself. It is built well. The caps are cheap. Tuning the bastard is not consistent, not fast, and highly touchy. The only loop worth purchasing is the Ciro Mazzoni loop from Italy sold by DX engineering. It will take abuse and has an excellent tuning feature that will follow your radio. Each time you change freq with the MFJ it is a task to get it to tune again. A friend of mine bought one and it was soon offered to me for $100. Then he became so frustrated with it that he wanted me to take it for free if I would dig the post out of the ground he mounted it on. I Passed knowing that any dipole would blow it away. Even an end fed random wire will beat it in performance if put up right. In the end there are many cheaper options that work far better than the MFJ mag loop. 73, Morgan NJ8M BS + MS + $2.98 = COFFEE Real Life Experience = Priceless, says the man who set his back yard on fire with a breadboard tuner loading a 160 meter inverted L with 1000 watts.

Retuning after changing freq is tiresome, but less of an issue if one is staying on the same freq (FT8, etc) and only needing to retune when changing bands. I received good signal reports and worked all states on FT8, but sold it after moving back to a house and needing a proper outside antenna.

Basically the same as disconnecting the connectors but without wearing them out. It would ?only? be there to protect against induced current in the short runs of wire in the shack. I know lots of people who disconnect their antennas here in Colorado in the summer, but I bet that not many people disconnect everything every time they walk away from the radio.

They seem to use direct in place of inductive coupling.? The automated tuning is cool, but requires a control cable to the antenna as well as coax.? My experience with MFJ resembles Morgan's, I wouldn't call them junk but they don't stand up well outdoors.? SML's, if the loop plane is vertical, tend to be insensitive to ground [i.e. height AGL] and surrounding objects if their permeability is close to 1.0. My permeability must be close to 1.0 because I sit under it and can reach up and tune it, and my presence doesn't seem to affect it. The Alexloop Walkham has a reduction gear on the capacitor but it's not enough and below 20 m the adjustment gets very touchy.

Works all HF bands, good for a KW [I run a K3/100], and runs circles around the Alexloop.

Radiation resistance of a small loop is 31,171 * (Area / wavelength^2)^2 For a loop with a 91cm diameter at 14 MHz, I believe that comes out to 0.064 ohms. Assuming the loss is due to the RF resistance of the loop: From the internet I get the volume resistivity and skin depth for 6063 aluminum is 0.03 microohms-meter and 23.3 micrometers respectively, so the surface resistivity is 0.03/23.3 = 0.0013 ohms per square.? The outside circumference of the tubing is PI * 1.05" = 3.3" and the loop length is PI * 36" = 113" so the loss resistance is .0013 * 113/3.3 = 0.045 ohms. So I calculate an efficiency of 0.064 / (0.064 + 0.045) = 59% So worse than AEA claimed, but in the ballpark.

At the time I was honestly not sure how else I'd have been able to have something permanently set up outdoors (unfortunately needed due to stucco construction) and HOA approved otherwise*, so there's definitely a market for them. In my experience, the "band change" buttons stop tuning when the SWR gets close--even when retuning within the same band--and the slow tune buttons seem to have enough granularity to allow someone to stop when the dip in reflected power happens. If one's loop doesn't do that, there's a pot that one can adjust inside the control box to fix that particular issue. Anyway, this thread does remind me that I should go back up and confirm the conductor diameter for sure; I had been assuming something close to 1" before but it's likely smaller than that. -Mooneer K6AQ * I only found out about the Isotrons after setting up the loop. Considering the supposed bandwidth of the 40m and up ones, it's possible I'd have gone with those instead (since less effort is always nice).

One thing that surprises me about magnetic loops is there high price. Anecdotally, my AlexLoop did an amazing job on 10-20m and was a really crap shoot on 40m. I think the numbers quoted might be very optimistic as I think on 40m (and 30m) a 3 ft magnetic loop is horribly inefficient. One thing I learnt from talking to Ciro Mazzoni is that the lobes created by these smaller magnetic loops are pretty high of the ground possibly with a concentration of power at 50-60 degrees off the horizon. That aside, my AlexLoop surprised me in early 2016 during NPOTA as I managed phone WAS using 10w portable from the San Francisco area. My Ciro Baby Loop seems to have no issue with stations out 2-3K miles but beyond that its a really luck of the draw and clearly tied to bands and propagation. From the UK on 20m and 40m I struggle to get East Coast stations. I?m happy to have the Magnetic Loops in my arsenal but would pick another antenna if circumstances dictated. Here is a short write up on my AlexLoop which I do like?..https://nomadic.blog/2018/09/20/oh-ye-of-little-faith-my-journey-with-an-alexloop/ Paul W6PNG/M0SNA www.nomadic.blog > On Jan 18, 2021, at 4:40 PM, Mooneer Salem wrote: > > FWIW, mine has worked fairly well (on the roof of my second floor condo) > since last year, moreso on 20 than 40 meters.

Message-ID: <017c01d6ee07$8ef6a980$ace3fc80$@comcast.net> The letters to this list regarding FCC and ARRL notices were factually false and have absolutely nothing to do with Elecraft products except perhaps as some might choose to use such radio transmitting products to commit unjustified criminal acts. Those who have false pride in their comments can read what I write here and readily determine their factual mistakes for themselves. The reason for the FCC and ARRL Notices is factually not because of the next administration but the present one which incited a riot. IN THAT CRIMINAL OFFENSE, Radios were used unlawfully to commit Federal offenses against democracy and the Constitution. I also see the FCC notice as one asking civilians to report criminal use of Amateur and other civilian communications gear - This I will do as well as working with other law abiding hams to find, locate and document criminal use, especially against the Constitution and US Government. The reason why Washington D.C. is an armed camp is that on 1/6 We had a president incite insurrection. That President is the only one with two impeachments, both of which are more legally substantive than the two which preceded them. Those persons criminally acted to disrupt lawful congressional preceding. Many claim to have done this on behalf of the current President, failing to understand nobody is above the law and any apparent direction to violate the constitution is illegal no matter the source. That entire event was unprecedented in the USA and the responses are and will be as well. The election was not fraudulent. It was certified in each of the states, in most cases by Republican elected authorities. Over 60 cases whose lawyers claimed fraud, were thrown out by Federal judges, many of whom appointed by the current President. In several cases these judges noted there was no evidence at all and in the rest, no evidence that would show a change in the end result for that state. The Supreme Court also spoke on this matter - against the Presidents false claims. There are over 60 case transcripts, public oral opinions by the judges and supreme court, as well as the remarks of AG Barr who quit in disgust with his own administration. Frankly to blame the next administration for the FCC and ARRL notice is idiotic - they are not in power yet. That assault on the Capitol was unprecedented and THAT is what has led to the other unprecedented things. The reason is that under our constitution, nobody is above the law, including the President and those who stormed the capitol. Acting to enforce the law should not be offensive to anyone who claims to be a patriot or writing in the traditions of Amateur Radio or the ARRL. Interesting to know the false sympathies of some of you though. I encourage you to spend the reasonable efforts of citizens to go and learn what you didn't.

A number of reviews I have read (including the QST review of August 1994) have reported comparable performance to full-sized wire antennas located on the same site.? If the loop is down by, say, 3 dB, that's only half an S unit, which would hardly? be noticeable in the QSB of a typical amateur band. As I see it, the advantages of the MFJ-1786 10-30 MHz loop are: - Continuous coverage on 6 amateur bands.? A convenient way to cover all the WARC bands. - Small and light. - Omni-directional (when mounted horizontally)? so does not need a rotor. - No control cable required - control voltage is fed through the coax. - Narrow bandwidth provides excellent RF selectivity.? Might be good on Field Day to reduce inter-station QRM. - Users have reported lower receiver noise compared to wire antennas.? No doubt that is because the isolated pickup loop prevents feedline radiation/pickup. And the disadvantages: - Expensive ($500 list price) - Less gain than a simple dipole (although you would theoretically need 6 of them). - Fiddly to tune.? If you QSY too far you have to re-tune. - MFJ quality control leaves something to be desired.? (You may have to open it up when you get it and? make minor repairs.) - You have to pay attention to the problem of entry of water and/or bugs into the housing. - The controller can be damaged by a DC short in the coax e.g. from an shorting-type antenna switch.? (I don't understand why MFJ didn't include a fuse or some other way to protect the controller.) I probably wouldn't buy the 7-21 MHz MFJ-1788 because of the poor efficiency at 7 MHz.? I think you'd have a better signal just using the coax as a random end-fed wire (with a tuner).

As I said, I don't have one so I can't say for sure.? I got my information from the MFJ web site:? "All welded construction, no mechanical joints, welded butterfly capacitor with no rotating contacts ... Each plate in MFJ's tuning capacitor is welded for low loss and polished to prevent high voltage arcing, welded to the radiator ...".? https://mfjenterprises.com/products/mfj-1786 Also, for what it's worth, some of the reviews on eham.com and qrz.com mention that it has a welded tuning capacitor. I got the impression that one reason people often receive units with bent capacitor plates is that they got bent in the welding process. It would be interesting to look at one and see what they actually mean by "welded".

The housing does not protect thecapacitors that are in house made and bugs can crawl into the housing andshort them out. Secondly, the plastic housing in Kansas will be destroyedby the sun. The best thing about the loop is the loop itself. It is builtwell. The caps are cheap. Tuning the bastard is not consistent, not fast,and highly touchy. The only loop worth purchasing is the Ciro Mazzoni loopfrom Italy sold by DX engineering. It will take abuse and has an excellenttuning feature that will follow your radio. Each time you change freq withthe MFJ it is a task to get it to tune again. A friend of mine bought oneand it was soon offered to me for $100. Then he became so frustrated withit that he wanted me to take it for free if I would dig the post out of theground he mounted it on. I Passed knowing that any dipole would blow itaway. Even an end fed random wire will beat it in performance if put upright.

The disconnect of thought (inability to see contradictions) cannot be resolved through partisan rhetoric because there is no desire for analysis, truth and reason to a partisan, only power. Emotion prevents clear thought. That's why, for the most part, ham radio is a pleasure as it encourages reason and clear thought (although not always). If the standard of logic is that Trump incited at the capitol (the group moved in before he spoke) then all the democrats who promoted violence for 9 months as redress should be impeached or in jail. Target the wrong doers or every protest from here on out will be "incitement" and blamed for the deeds of individuals. Dangerous thought error.

Other NRTLs can do the same, and there are quite a few. A manufacturer needs to have their products certified by an NRTL if fed, state, or local regulations require it, or customers (often large entities) require it.?

The K4/K4D are "pure" SDRs, meaning they're more agile in frequency, operating modes, modulation and demodulation, features in general, and extensibility. A lot of the flexibility of the design is in service of the built-in and external displays as well as remote control. The K4/K4D also have a lot more digital and RF I/O, satisfying the demand for a modern, integrated station. For example you can directly attach a keyboard, mouse, HDMI monitor, and flash storage drives or other USB devices. By contrast, the K3S is a superhet, with emphasis primarily on receive close-in dynamic range performance rather than integration, agility, extensibility. The use of crystal filters is an advantage in raw performance, at the expense of passband flatness, available bandwidths, and group delay. The K4HD will be a hybrid of the two: When the extra dynamic range is needed, you can turn on the HDR module, which is essentially two superhet downconverters, one for the main receiver and the other for the sub. But the HDR module is, in practice, rarely needed unless you have high-power transmitters in close proximity. Examples of this situation include multi-transmitter contest or DXpedition stations, those living in the shadow of a broadcast station, and those with very nearby ham neighbors. With this context we can now talk about receiver performance. - The K4/K4D are very similar to competing pure SDRs using 16 bit, wide-band A-to-D converters: signal handling is excellent by any measure, and there's plenty of headroom in all but the most heavily impacted RF environments. - Compared to *any* pure SDR, the K3S (and a few other superhets) will have a few dB higher third-order intercept point. (Note that Sherwood's chart still shows the Flex 6700, a pure SDR, at 108 dB. He corrected this later to a much lower number -- see the '6700 footnotes in the far right column.) - The K4HD will be in the same ballpark as the K3S, though we're still refining the design and our goal is for it to be higher. (The limitation with any superhet is the crystal filters, and we carefully control the quality of our suppliers.) 73, Wayne N6KR From wa8hgx at gmail.com Tue Jan 19 13:40:28 2021 From: wa8hgx at gmail.com (BRUCE WW8II) Date: Tue, 19 Jan 2021 13:40:28 -0500 Subject: [Elecraft] K4 Receive Filter question In-Reply-To: <220662604.622403.1611070944735@mail.yahoo.com> References: <492525755.2027750.1611035033751.ref@mail.yahoo.com> <492525755.2027750.1611035033751@mail.yahoo.com> <220662604.622403.1611070944735@mail.yahoo.com> Message-ID: I work in the 2 to 3 db above the noise floor CW, and 6 to 10 db above the noise floor on SSB now, (that is why I presently own a K3s and a P3VGA) so I guess I will have to wait for the real answer. I really cannot believe that Elecraft did not run their own test. If and when I spend my cash I am not looking for the pretty blinkie colored lights and a fancy screen, I want performance. My really big issue is: receiver noise floor, sensitivity and DSP that does not distort or degrade the incoming signal. But thank all of you for your input and I truly appreciate all the comments.

My 20 year old K2 is essentially equal at digging weak CW out of the noise (always dominated by band noise and not the noise floor of the rig) in virtually all situations I've run into. The K2 has no KSSB so I don't compare it on SSB. If I was up against a lot of really strong close-by sigs, presumably the new rig would win, but I haven't yet run into a situation with the two rigs side by side where big nearby sigs have actually caused a discernible difference. Comparing SSB with other rigs, the new rig can beat the others on readability of weak sigs in noise, but I don't think it's due to the fundamental performance numbers in these cases but rather the DSP algorithm which makes the difference, and I don't believe this is quantified in the testing done by Sherwood or ARRL, except perhaps in subjective comments in the text of a QST review. .

We'd remove many of the rotor plates and re-pad it with a fixed capacitor to spread out the ham band on the dial.? It took a lot of bending back and forth to break the welds.? Lower power loops often use butterfly caps since there is no resistive loss through the rotor connection.? Higher powered loops often use vacuum variables because of the high voltages, although I saw a design not long ago that used two coaxial copper pipes with a PVC pipe as the insulator.? The inside conductor was mounted to a long threaded rod moving it in and out of the outer conductor. In your list of pros, you might note that while the bi-directional primary lobes of the loop when mounted vertically are very broad, the null perpendicular to the plane of the loop is extremely narrow and deep.? You can use it to null out noise or even another signal without sacrificing much of anything in the forward direction. My Alexloop works ok on 30, poorly on 40, and really seems to come into its own on 20 and up. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/18/2021 8:54 PM, Alan Bloom wrote: > > There is a reason why top quality variable capacitors often use > welded plates. > > I believe they do weld the capacitor plates and also weld the loop to > the capacitor.?

Message-ID: This new OT topic and the preceding old OT topic combined has been one of the greatest examples of free speech I have ever seen on-line. Kudos to this forum for open and honest participation, it fills me with hope to see such a wonderful exchange of contrasting viewpoints without digital censorship. It may be ?OT? but the unprecedented notice by the FCC and the ARRL should be openly discussed by all licensees.

So I re-did the calculations using the 59% efficiency figure calculated below.? The new results can be downloaded here: https://www.dropbox.com/s/ve1v49b3gjvmt64/MFJ-1786-1788_2.pdf?dl=0 If you don't want to download the (1-page) document with the pretty graph, here's a synopsis of the results: Freq? ? ? Eff.???? Gain with respect to a 1/2-wavelength dipole MHz?? ?? dB????? dBd 7.0??? ? ?? -9.5??? -9.9 10.1?? ? ? -5.1??? -5.5 14.0?? ? ? -2.3??? -2.7 18.068 ? -1.1??? -1.5 21.0?????? -0.7??? -1.1 24.89???? -0.4??? -.8 28.0?????? -0.26? -0.65 My basic conclusions still stand.? With almost minus 10 dBd of gain on 7 MHz, the 40 meter coverage of the MFJ-1788 doesn't seem very useful.? That is confirmed by some of the reviews I have seen.? I think you'd get better results by just loading up the coax feedline as a random-wire antenna with a tuner. The 10 MHz performance is a little better.? Good enough to at least allow you to get on the 30 meter band. On the higher bands, the gain is within less than 3 dB of a full-sized dipole, which seems a useful trade-off for its small size and wide-band continuous coverage. Disclaimer:? Again, I have never seen one of these things so this is all based on theory and on the many reviews I have read.? Even if my figures are off a bit, at least this gives an idea of the relative performance on the various bands.

It'd be a little more than 4' in circumference, 16" dia,? and the capacitor could be be two 4 cm diameter plates ~2mm apart. That should be reasonably easy to make relatively efficent as there are not a lot of plates that need to be connected with very low resistance.? I calculate ~85% with 1/2" copper.? Should be good for 200W.? I'd orient it horizontally for horizontal polarization (weak sigs) and local noise rejection. I have a squalo made from a lawn chair, but technically that's not a small loop and a little big to be stealth.

With almost minus 10 dBd of gain on 7 MHz, the 40 meter coverage of the MFJ-1788 doesn't seem very useful.? That is confirmed by some of the reviews I have seen.? I think you'd get better results by just loading up the coax feedline as a random-wire antenna with a tuner. The 10 MHz performance is a little better.? Good enough to at least allow you to get on the 30 meter band. On the higher bands, the gain is within less than 3 dB of a full-sized dipole, which seems a useful trade-off for its small size and wide-band continuous coverage. Disclaimer:? Again, I have never seen one of these things so this is all based on theory and on the many reviews I have read.? Even if my figures are off a bit, at least this gives an idea of the relative performance on the various bands.

The inside conductor was mounted to a long threaded rod moving it in and out of the outer conductor." Not my original idea but that's what I have on my loop (PEX insulator not PVC). Works fine up to 100 W on 30 m but has SWR runaway at 150 W. Capacitor is driven by a geared DC motor and is tuned from the shack. Home brew is far more fun than buying commercial.

However, none of them talk about what I see as one of the most important performance characteristics, which is the user interface (UI). How easy it the radio to use? For me, I do a lot of digital modes. Here I want to monitor all of the power output, SWR, and ALC. On my K3, I have to switch between them. On the K4 I can have them all on the screen. How easy is it to tune to a signal I see on the panadapter? On the P3, I need to move the cursor (via a knob) to be on top of the signal and press a button. Honestly, it's easier to turn the big knob. On the K4 I touch the touch screen. (I hope this screen is better at detecting my touch than my iPhone.) There are probably a bunch of other examples too. And, since I'm interested in remote operation, I think that will be a lot easier with a K4. And I haven't even mentioned TX or RX performance. But it's an Elecraft, so I'm not worried. 73 Bill AE6JV On 1/19/21 at 1:40 PM, wa8hgx at gmail.com (BRUCE WW8II) wrote: >If and when I spend my >cash I am not looking for the pretty blinkie colored lights and a fancy >screen, I want performance. ----------------------------------------------------------------------- Bill Frantz | Truth and love must prevail | Periwinkle (408)348-7900 | over lies and hate. | 150 Rivermead Rd #235 www.pwpconsult.com | - Vaclav Havel | Peterborough, NH 03458 From chrisc at chris.org Tue Jan 19 21:32:34 2021 From: chrisc at chris.org (Chris Cox, N0UK) Date: Tue, 19 Jan 2021 20:32:34 -0600 Subject: [Elecraft] Mag Loop from MFJ In-Reply-To: <5BF4C940-480F-4A1C-866F-50E5DC81B29A@mchsi.com> References: <2bcebf99-06b4-c4ad-0c7e-dc2c546dfb63@foothill.net> <7c566aee-97c6-73a1-dd8d-2119d151555e@foothill.net> <5BF4C940-480F-4A1C-866F-50E5DC81B29A@mchsi.com> Message-ID: <0058AA1A-DB50-41D7-BCFC-0CB6099C0A4E@chris.org> FWIW - I invested in an MFJ-1786 when we moved into our apartment 6 1/2 years ago. Since then, kit has been out on our 5th floor balcony in central Minneapolis year round, easily standing up to both Minnesotan Winters and Summers with aplomb. It has not ceased to work in that time and has netted me ~150 DXCC?s on all bands from 30 through 10 metres. Most of my work is CW by preference although I did break a pile-up a couple of years back to work VP8 on 20m SSB from an ATNO. To say I am pleased with its performance and capability may be understatement of the decade! I am absolutely gobsmacked at how well such a physically small antenna plays on HF and am willing to stand up for MFJ (at least in this particular case). YMMV, of course?

Bravo! I wonder if the SWR runaway at 150W could be due to the PVC pipe used as the insulator for the variable capacitor?? PVC is quite lossy at RF.? Perhaps when it gets hot it detunes the capacitor.? It would be easy to check by simply feeling the cap to see if it gets warm.

The comments are that at that low power the fan may not keep the equipment cool enough. One suggestion was to transmit at a higher power, and another was to schedule a break every few minutes to allow the rig to cool. I will appreciate you sharing any information or experience you have. I am getting ready for Winter Field Day and hope to make many PSK31 contacts. ________________________________ From: elecraft-bounces at mailman.qth.net on behalf of elecraft-request at mailman.qth.net Sent: Tuesday, January 19, 2021 5:56 PM To: elecraft at mailman.qth.net Subject: Elecraft Digest, Vol 201, Issue 26 Send Elecraft mailing list submissions to elecraft at mailman.qth.net 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..."

I also would be reluctant to upgrade to a K4 if my K3 is the same or pretty close to the same in the key performance characteristics. I wonder whether we are nearing the theoretical limit of what can be gained in receiver performance. The difference among the top eight to ten on the Sherwood list is not likely to be practically significant. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of BRUCE WW8II Sent: Tuesday, January 19, 2021 10:40 AM To: Louandzip Cc: elecraft Subject: Re: [Elecraft] K4 Receive Filter question I work in the 2 to 3 db above the noise floor CW, and 6 to 10 db above the noise floor on SSB now, (that is why I presently own a K3s and a P3VGA) so I guess I will have to wait for the real answer.

My 20 year old K2 is essentially equal at digging weak CW out of the noise (always dominated by band noise and not the noise floor of the rig) in virtually all situations I've run into. The K2 has no KSSB so I don't compare it on SSB. If I was up against a lot of really strong close-by sigs, presumably the new rig would win, but I haven't yet run into a situation with the two rigs side by side where big nearby sigs have actually caused a discernible difference. Comparing SSB with other rigs, the new rig can beat the others on readability of weak sigs in noise, but I don't think it's due to the fundamental performance numbers in these cases but rather the DSP algorithm which makes the difference, and I don't believe this is quantified in the testing done by Sherwood or ARRL, except perhaps in subjective comments in the text of a QST review. .

The K3S is set up in a receive-only state, sharing the RX antenna out of the '890. A few mornings ago I was tuning 160 near sunrise and copied a fishing buoy 60 Hz above one of the commonly used frequencies (forget which one).? My friend, and local ham, N7DD began calling CQ 60 Hz below the buoy.? Larry runs an Icom 7851, which is very clean and a BIG amplifier.? He is at least S9+40 db.? On the TS-890, cranked down to 80 Hz BW,? I could still copy the buoy which was S6 or so.? On the K3S I heard N7DD calling CQ.

We'd remove many of the rotor plates and re-pad it with a fixed capacitor to spread out the ham band on the dial.? It took a lot of bending back and forth to break the welds.? Lower power loops often use butterfly caps since there is no resistive loss through the rotor connection.? Higher powered loops often use vacuum variables because of the high voltages, although I saw a design not long ago that used two coaxial copper pipes with a PVC pipe as the insulator.? The inside conductor was mounted to a long threaded rod moving it in and out of the outer conductor. In your list of pros, you might note that while the bi-directional primary lobes of the loop when mounted vertically are very broad, the null perpendicular to the plane of the loop is extremely narrow and deep.? You can use it to null out noise or even another signal without sacrificing much of anything in the forward direction. My Alexloop works ok on 30, poorly on 40, and really seems to come into its own on 20 and up. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/18/2021 8:54 PM, Alan Bloom wrote: > > There is a reason why top quality variable capacitors often use > welded plates. > > I believe they do weld the capacitor plates and also weld the loop to > the capacitor.?

The problem with political discussions - especially in the world of 24/7 news coverage and op eds - we all show how uneducated we are on the topics and are willing to believe what we are told without doing the research. The rhetoric is all too often divisive. We can all agree on how fun and fulfilling ham radio is to each of us in its own special way - let's stick to that.

I think you'd get better results by just loading up the coax feedline as a random-wire antenna with a tuner. The 10 MHz performance is a little better.? Good enough to at least allow you to get on the 30 meter band. On the higher bands, the gain is within less than 3 dB of a full-sized dipole, which seems a useful trade-off for its small size and wide-band continuous coverage. Disclaimer:? Again, I have never seen one of these things so this is all based on theory and on the many reviews I have read.?

With ant restrictions, I'm looking at building a small horizontal loop for 6m.? It'd be a little more than 4' in circumference, 16" dia,? and the capacitor could be be two 4 cm diameter plates ~2mm apart. That should be reasonably easy to make relatively efficent as there are not a lot of plates that need to be connected with very low resistance.? I calculate ~85% with 1/2" copper.? Should be good for 200W.? I'd orient it horizontally for horizontal polarization (weak sigs) and local noise rejection. I have a squalo made from a lawn chair, but technically that's not a small loop and a little big to be stealth.

PVC is quite lossy at RF. Perhaps when it gets hot it detunes the capacitor. It would be easy to check by simply feeling the cap to see if it gets warm." The insulator/dielectric is PEX not PVC. I have studied the impact of temperature on the antenna and it exhibits some interesting and sometimes non-intuitive effects. The biggest change is seen when the sun hits the antenna soon after run rise. Study of heating during TX would require sensitive thermal imaging. There is no change detectable by touch after a TX. Touching it while transmitting would be counter productive and perhaps painful. I have lots of notes and some plots of the thermal characteristics. Maybe I'll get back to working on it one day. 73, Andy, k3wyc From nv4c.ian at gmail.com Wed Jan 20 12:41:22 2021 From: nv4c.ian at gmail.com (Ian Kahn) Date: Wed, 20 Jan 2021 12:41:22 -0500 Subject: [Elecraft] K3 PSK31 transmit at what power out?

Looks like we've both had some fun with these antennas that have become quite popular in recent years. My interest in Mag Loop antennas started back in the early 1980s, and I have designed and built a couple of dozen over the years since, mostly as experiments to gain knowledge and experience, and several to help friends who lived under extreme antenna restrictions. The two pictures in this Dropbox folder show one incarnation of a mag loop that uses flat mill stock for the main loop, and a trombone-style capacitor for tuning: https://www.dropbox.com/sh/gqbzz60bcwkc54h/AACAjWK6JFfyLN9qcvq9oSrqa?dl=0 My capacitor design uses PEXX tubing for the dielectric layer (must be protected from UV), and has fiberglass stiffeners inside the sliding part. The PEXX allowed me to run up to about 300 watts. And the stiffeners hold the tubes in line at the low capacity end of travel to prevent misalignment (sloppy tuning). I long ago moved to all copper loops and vacuum variables to handle high power and obtain better efficiency. An example of a two-turn version of a 40-80m mag loop is on my QRZ.com page: ??? https://www.qrz.com/db/KB0YH It uses 7/8" Heliax (the shield) as the main loop conductor. Kinda heavy, so some of my newer mag loops use 1/2" Heliax or soft copper tubing instead. Performance suffers a little, but no one notices the difference. Have fun and keep safe.

One of the materials was not appropriate, but I made it work for the sake of the experiment. I plan to make another loop at some point from a different material so it's not an issue, but that was only the *support* material for the loop. I wanted a loop I could fold or roll up into a small package to take it to parks and such, that wouldn't require stakes or lofting things into trees, in case the local authorities don't like that. The support material was some plastic perforated strap for supporting pipes, conduits, and BX cables in basements and attics. The holes are an inch apart on centers, and the stuff is VERY strong. It's also flexible...but TOO flexible. It had no supportive strength whatsoever, which was a problem for this project. I wound up making supports for it out of thin wood, which worked, but it wasn't what I originally had in mind. But it's not the support material I'm writing this to mention. I'm talking about the conductor. I used 1/2 inch wide adhesive copper foil. The adhesive is also conductive. It's not very strong, but it's VERY conductive, and it's lack of thickness isn't an issue because it has a lot of surface area, where the RF is actually conducted, so it should have great bandwidth. I had a decent variable air-gap capacitor, with a 10X vernier control on it, and used a small wooden base, like a miniature pallet, as a platform for the entire thing. I priced thin wooden furring strips for the rest of the supports, but they were more expensive than I liked. So I bought a dozen wooden meter-sticks for about half what the furring strips would have cost. They work very well for situations where you need a thin but strong piece of wood. I ran the copper foil tape the length of a piece of the plastic strap to give me a loop I calculated for 40m-10m. The copper foil takes solder very nicely, so it was simple to work with. The wooden supports I made were a six-pointed star, the bottom being flattened for the connections at each end of the loop and the capacitor. I made a coupling loop out of a similar piece of plastic strap and the same foil tape, and connected it to the coax, about 15 feet of RG-174. I used this loop indoors, on a wire rack next to my workbench, and used it with FT8 at various output power levels. I used a laser thermometer to check the temperature of the conductor in multiple places, and it only showed a tiny increase in temperature above room temp when I tried it with 100W. (KX3 + KXPA100) It was easily tuned on the bands I expected to use it with, and with the internal tuner of the amp I managed to tune it on 80m, but didn't expect any significant efficiency, and was right not to expect it. But on 40m through 10m it was very serviceable. I'm in the Philly area, and managed to have FT8 contacts as far as Fargo, ND and a couple in Cuba. The bandwidth was fairly wide as I expected. I haven't used it to try and make CW or SSB contacts, but I see no reason why I couldn't, though it is firmly in the "compromise antenna" category for those emission types. It's a proof-of-concept, mostly, but a functional one. I've attached pictures, so you can see what it looks like. -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Wed, Jan 20, 2021 at 10:50 AM Raymond Sills via Elecraft < elecraft at mailman.qth.net> wrote: > Hi Group: > OK... here's my mag loop story: > I have two AlexLoops.... and one is the original version that uses copper > tubing for the main loop.

This makes the characters at higher speed ~50WPM vy hardly readable by the QSO partner. Experiments with "CW WGHT" do not lead to success. At higher speeds, my friend therefore switches to the mode "CW QRQ = On", where the effect does not occur. However, some functions (RIT, SPLIT) are unfortunately not available there. Therefore, this is not an ideal solution. So far I have not found any clues to help him solve the problem. Are there other setting possibilities to solve this issue, or can there also be a hardware problem here? 73, Wolfgang DL2KI -- Sent from: http://elecraft.365791.n2.nabble.com/ From gt0hof at gmail.com Fri Jan 22 07:24:46 2021 From: gt0hof at gmail.com (Ken Barnett) Date: Fri, 22 Jan 2021 12:24:46 +0000 Subject: [Elecraft] K3s For Sale Message-ID: <2A5168B0-DAD8-48F2-A7FB-E15233F8CFB4@hxcore.ol> From oldmanshu at icloud.com Fri Jan 22 09:34:17 2021 From: oldmanshu at icloud.com (Joseph Shuman) Date: Fri, 22 Jan 2021 09:34:17 -0500 Subject: [Elecraft] KXPA100 Mount Screws Message-ID: There are 4 locations on the lower sides of the cover for mount screws.

It's great, close to the theoretical optimum of sounding like a code practice oscillator running in the background! Remarkably, it sounds the same in TEST mode as when transmitting 100W barefoot, 1200W (ICOM 1000 vacuum relay), or 1500W (KPA1500 PIN diode), internal keyer or external WinKey emulator. No, it's not perfect. I don't hear much received signal between dits at 50 WPM, but I do hear something noticeable when there's a signal there. And at a more realistic 38 WPM, sending actual code, I can tell *immediately* when there's something on frequency. Wayne tells me that he has a few more tricks up his sleeve that can make it better yet, but it's already among the best QSK setups I've ever experienced.

Yes, when searching the mailing list, it depends a lot on the search terms. So sometimes the search is a bit difficult. I will therefore continue to search with other terms. The issue occurs with the K3 internal keyer and is already audible even at speeds below 50 WPM. The use of an external keyer would be a solution, but since the effect does not occur with my K3, for example, the sound of the CW characters should actually be equally good with all K3's. Already experimented with different menu parameters. "TX DLY" is set to "008". But on the basic problem this had so far no influence. I have therefore rather the assumption that here somewhere a hardware problem is present with this special K3. 73, Wolfgang Dl2KI -- Sent from: http://elecraft.365791.n2.nabble.com/ From KK at ccf.net Sat Jan 23 05:33:37 2021 From: KK at ccf.net (Klaus Koppendorfer) Date: Sat, 23 Jan 2021 10:33:37 +0000 Subject: [Elecraft] K3: CW characters sound very hard / short In-Reply-To: <1611296571673-0.post@n2.nabble.com> References: <1611296571673-0.post@n2.nabble.com> Message-ID: Put KSYN3A Synthesizer Upgrade Boards into your K3 and CW Chars are ok at QRQ high speed Have done this mode on my K3 and got an completly another Radio also on receive 73 Oe6kyg -----Urspr?ngliche Nachricht----- Von: elecraft-bounces at mailman.qth.net Im Auftrag von dl2ki Gesendet: Freitag, 22.

That was not directly discussed but I'll bet the answer is no. I'm sure you could use a keyboard to send CW but I'm not sure that capability will be built into Elecraft's remoting software. For my own interim remote setup (I'm waiting on the K4/0), I found a client server application (df3cb.com) that uses a WinKeyer to give you paddle CW. It requires a WinKeyer on BOTH ends of your remote. The idea is that you are paddling your local WinKeyer and it is talking to the remote WinKeyer which is connected to your remote rig. That same remote capability is built into a WinKeyer (https://www.hamcrafters2.com/files/WKremote.pdf) and called WKremote by K1EL. I didn't use that because I have a YCCC SO2R Box (which emulates a WinKeyer V1, I think) at my station so since I didn't have two WinKeyers, I tried the DF3CB idea and it worked! You need to turn off the sidetone monitor on your rig and use the sidetone of your local WinKeyer but it works fine when you want to use a paddle for remote CW.

The K3 utility failed, RUMlogNG failed, and wsjt-x failed. I found the following by robertklep on the web: What seems to have worked for me is actually removing the FTDI driver (/Library/Extensions/FTDIUSBSerialDriver.kext), after finding that Apple ships an FTDI driver with the OS itself (/System/Library/Extensions/AppleUSBFTDI.kext).

I realize in some cases that might be too fast for the K3, but play with that. Also, serial ports are typically these days ?eight, one, none.? I see you have ?eight, TWO, none.? Make sure your port is really configured that way. Unless you explicitly set it for two stop bits, it?s likely defaulted to eight, ONE, none. One stop bit is generally quite adequate. 73, David - N5DCH > On Jan 23, 2021, at 5:23 PM, Richard wrote: > > Well, here?s where we are.

In the K4 it takes the form of distributed processing, including multiple high-speed FPGAs in the demodulation path, a new DSP that's twice as fast any we've used before, and virtually unlimited resources in our main processor. It's also a very modular radio. For example, if a higher-performance A-to-D converter becomes available in the future, we'll be able to offer an upgraded digital downconversion module. 73, Wayne N6KR > On Jan 24, 2021, at 8:35 AM, wrote: > > For many years dynamic range and other receiver performance figures (see Sherwood) and digital ?features? like NB, NR, APF, Notch etc got a lot of attention (which was good). > > The transition from hardware to software opened a new world of possibilities. > > But ?. > > Today, most of us are battling near-field man made noise instead of receiver overload. > > Reality tells us that this noise is not going to reduce the next decade or so. > > Receivers will outperform competitors if they enable noise reduction and improve S/N ratio. > > This will be a combi of hardware (antenna?s and receivers) and smart software solutions (algorithms etc.) > > > > Just wondering if during the K4 design this ?chance? was considered and if so, how this was implemented ? > > > > 73, Evert PA2KW > > > > (waiting for the K4 kit) > > > > > > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to n6kr at elecraft.com From jstengrevics at comcast.net Sun Jan 24 12:07:40 2021 From: jstengrevics at comcast.net (John Stengrevics) Date: Sun, 24 Jan 2021 12:07:40 -0500 Subject: [Elecraft] Different focus In-Reply-To: <004601d6f26e$f86c9bc0$e945d340$@pa2kw.com> References: <004601d6f26e$f86c9bc0$e945d340$@pa2kw.com> Message-ID: Evert, As one who suffers from such noise, I too look forward to such improvements. The K4 will have a ?subtractive? noise reduction/noise blanking algorithm that essentially subtracts noise form a signal being copied. During the recent Zoom call, I was told it would be available in about 3 months. I think you can find a demonstration of this on YouTube somewhere. It is very impressive. 73, John WA1EAZ > On Jan 24, 2021, at 11:35 AM, wrote: > > For many years dynamic range and other receiver performance figures (see Sherwood) and digital ?features? like NB, NR, APF, Notch etc got a lot of attention (which was good). > > The transition from hardware to software opened a new world of possibilities. > > But ?. > > Today, most of us are battling near-field man made noise instead of receiver overload. > > Reality tells us that this noise is not going to reduce the next decade or so. > > Receivers will outperform competitors if they enable noise reduction and improve S/N ratio. > > This will be a combi of hardware (antenna?s and receivers) and smart software solutions (algorithms etc.) > > > > Just wondering if during the K4 design this ?chance? was considered and if so, how this was implemented ? > > > > 73, Evert PA2KW > > > > (waiting for the K4 kit) > > > > > > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to jstengrevics at comcast.net From aa4lr at arrl.net Sun Jan 24 12:59:57 2021 From: aa4lr at arrl.net (Bill Coleman) Date: Sun, 24 Jan 2021 12:59:57 -0500 Subject: [Elecraft] Different focus In-Reply-To: <146C68C7-487A-49D0-A8F1-DA41D57505F1@elecraft.com> References: <004601d6f26e$f86c9bc0$e945d340$@pa2kw.com> <146C68C7-487A-49D0-A8F1-DA41D57505F1@elecraft.com> Message-ID: <1AE59309-0CEB-46AD-84BE-CCB151EB6622@arrl.net> But wouldn?t a higher performance A/D converter also mean you?d have to bring forth more DSP computing power?

Yes: More bits than 16, more monotonicity in the LSBs, general improvement in SFDR, or lower internal noise. Adding more ADC bits does not require more DSP horsepower. The DSP is 32 bit floating point.

(Yes, it would even work on Fitzroy Island if you had an internet connection.) This is in addition to direct K4-to-K4 control. Th VK4 application will eventually run on multiple platforms, including pads and laptops. It will support direct touch as well as mouse control, including the very useful mouse wheel for adjusting simulated rotary controls. We're fleshing out the various data streams including audio, panadapter, and CW keying. Of course third-party developers are free to create their own interfaces using the K4's extensive remote-control command set. If you missed it, here's a directly link to the Virtual K4 concept drawing. You can also get to it on our K4 page, in the "K4 Updates" section. https://ftp.elecraft.com/K4/virtual_K4_app.jpg (The sharp-eyed will notice a few features in the app that don't appear on the K4 front panel itself.) If you have comments or suggestions, feel free to send them to me directly or discuss on your favorite list. Note: In general we post everything of interest to the primary Elecraft reflector (this list). Postings to other lists may be more sporadic, so be sure to check here as well. 73, Wayne N6KR From kl7uw at acsalaska.net Sun Jan 24 14:17:21 2021 From: kl7uw at acsalaska.net (Edward R Cole) Date: Sun, 24 Jan 2021 10:17:21 -0900 Subject: [Elecraft] Automatic lightning protection for radios Message-ID: <202101241919.10OJJfgs015371@mail41c28.carrierzone.com> This is a little bit "tongue-in-cheek" reply: Only sure way to avoid lightning is to live where there is no lightning. I happen to live in such a location. We hear thunder every other year and see.see/hear lightning about once out of four years. Odds of an earthquake or volcano eruption is much higher (in Alaska on the "ring of fire") with four active volcanoes within sight (closest is 50-mile away and has erupted three time while I have lived up here). There are 141 active volcanoes in Alaska roughly aligned along the Aleutian island chain and Alaska Peninsula. I live at the northern end of that. The climate is maritime as I live two miles from Cook Inlet which is a 200+ mile long salt-water sound extending from the Northern Pacific. So we do not get the extremes in temperature that produces lightning (summer average 55-65F). Only 70-miles north Anchorage gets more of that weather. Interior AK gets hundreds of strikes per day in summer. location-location 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From k8tb at bosscher.org Sun Jan 24 15:51:30 2021 From: k8tb at bosscher.org (Tom) Date: Sun, 24 Jan 2021 15:51:30 -0500 Subject: [Elecraft] Virtual K4 application -- sneak preview In-Reply-To: References: Message-ID: Way cool screen saver Wayne !?

Never noticed this until I tried FT4 which is set for 18104 in the WSJT canned freqs and with the auto offset to keep audio clean when it switches TX VFO to 18103.5 the KAT cycles TX -then back on RX -- not needed for ant whatsoever its under 1.2:1 matched. across band . The 18014 switch point is still there with N1MM and WSJT not loaded - . AUTO or MAN -happens to be ant 2 .(BTW swr is better than 1.2:1 across band with one tuning point. If I train at 18106 on the dummy load - (ANT3) its not there but the swr is under 1.2:1 on DL matched. Yes I know the K3s/KAT/KPA is supposed to be protecting against high swr during switching - but it doesnt know that until it puts out a Rf pulse. Bottom line how do I move the 18104 KAT500 switch point ? Another thing I noticed as I was going across band the 18168 band edge does NOT keep from transmitting above 18168 if you go to 18167..99 it txes -then lift key and go to 18174 or whatever it tx es full power with key down one time,lift key then the band end is functional and no tx.

It may work for the LiFePO4, but that is just a guess on my part based on the terminal voltage. Secondly, you should not exceed 15 volts, so a 4 pack of Li-Ion exceeds that voltage. Then there is the matter of charging a battery different than an SLA. Use a charger that matches the battery chemistry chosen. You could add a direct connection to the battery to plug in the charger. See my website www.w3fpr.com for some ideas - do NOT eliminate the fuse inside the K2 - it is important because a battery contains a LOT of energy and can cause fires and spew molten metal should a short occurs.

Thanks for all the replies! There are some options that I don't care about, like the extended receive range. I would like the I/O board, DVR, 100w, ATU. Not sure about the transverter but if I find a K3 that has it, fine. Is the main reason for getting the transverter option is so you can use the 144 option? I'm using the recommendation from the Elecraft website to determine the best choice of filters - 2.8, 2.1, 400, 250 & 200. 99% of what I do is CW and contests.

We (K8AJ and myself) will be buying a K4, but when it shows up, um, she gets primary use of it. I'll be allowed to use the K3 and any leftover antennas. So I had better make the K3 the best I can.

I don't know the specs on the Y Box. Since I had just moved my radios around I needed a longer cable to go from my K3 ACC to TopTen band decoder, I was looking for a 15 pin straight through extension cable, M/F. I misread Jim's post and thought he was looking for an extension cable as I was. I had already bought three extension cables that looked like they would do the trick, but one after the other wasn't what I needed. The first one that was advertised as straight through actually wasn't and the other two both had connectors on the K3 ACC end that were molded such that they couldn't turn and be screwed in to the K3 ACC nuts. That wasn't obvious from the photos. The extension cable in the link arrived today and works as I desire. 73, Ken, K6LA / VY2TT On Sun, Jan 24, 2021 at 5:13 PM Bob Wilson, N6TV wrote: > This appears is the same Amphenol cable that I supply with my devices, for > $12 ea. if purchased with S-BOX or Y-BOX ($10 for a 2.5-ft version).

That is more than a little disappointing as it means that as a contester for example, you either have to have two or more displays (ie. One for a logging program & one for the K4 display) or buy a much more expensive display which enables you to have separate quadrants for separate programs? This seems a rather retrograde step compared to most other current transceivers or have I misunderstood? I suppose you could use the touch screen display as an alternative but why not output the K4 display to your PC and then put both outputs onto a single screen? 73 Ray G3XLG Sent from Mail for Windows 10 From ghyoungman at gmail.com Tue Jan 26 09:58:42 2021 From: ghyoungman at gmail.com (Grant Youngman) Date: Tue, 26 Jan 2021 09:58:42 -0500 Subject: [Elecraft] K4 Panadaptor Display In-Reply-To: <60102c46.1c69fb81.8aa2.bfd6SMTPIN_ADDED_BROKEN@mx.google.com> References: <60102c46.1c69fb81.8aa2.bfd6SMTPIN_ADDED_BROKEN@mx.google.com> Message-ID: <53FEEA86-43C2-4F73-89C0-02EB4184BCC3@gmail.com> I display, whether physical or logical (e.g, a quadrant of a real display), only supports a single input ? it has no means to ?window-ize? multiple inputs. Thinking about this some more, it seems it should be possible, eventually, to put a piece of remote software on the same machine that runs your other radio apps, and accomplish what you want to do. You can still only have one display controlled by one computer, but that one computer could be running multiple apps including a remote K4 display in a window.

I spent four or five hours working DX with it on 30-meter FT8 last night, and that setup worked PERFECTLY every time: Transmit start and Transmit stop times right on the money. I mean, it was PERFECT! I thought I was home free. I took screen shots of every Preference panel, the Mac Sound thing, even the Audio MIDI Setup panel in the Mac mini. BUT! When I fired it up this morning (Jan 25), it was right back to starting Transmit late and not coming out of Transmit? at all. I have to tap the XMIT button to stop it. What the hell??? What could change overnight? I didn?t touch anything when I shut down last night or when I fired up this morning. HOWEVER, as the afternoon and evening arrived, those symptoms went away and the setup was perfect again! MORE HOWEVER, This morning, Jan 26, the symptoms were back again.

There are solutions already available. According to the K4 Programmer's manual (available from the elecraft web site), "The K4 provides three kinds of streaming data: ..., dB/bin (for reproducing panadapter data), ..." This kind of dB/bin data can be used by a logging program to create a spectrum/waterfall display integrated with the rest of the program, supporting features such as display of call signs with multiplier.worked before status, and jump-to-signal capabilities using keyboard hotkeys or mouse clicks, all without looking at or touching the radio. N1MM Logger+ has had this kind of capability for nearly four years, taking advantage of dB/bin data supplied in the radio control stream by some radios (e.g. Icom IC-7300 and newer) or in a UDP stream from a radio or from other software (the UDP protocol used by N1MM+ is documented at < https://n1mmwp.hamdocs.com/appendices/external-udp-broadcasts/#sending-spectrum-data-to-n1mm>). There are other logging programs with some of the same capabilities, with no need for VNCs, HDMI capture, fancy picture-in-picture monitors, etc. 73, Rich VE3KI From backhoeken at yahoo.com Tue Jan 26 11:52:32 2021 From: backhoeken at yahoo.com (Ken B) Date: Tue, 26 Jan 2021 16:52:32 +0000 (UTC) Subject: [Elecraft] Headphones for Hearing Loss In-Reply-To: References: Message-ID: <1879251666.222335.1611679952373@mail.yahoo.com> Following with great interest - as have a similar issue?

Making one single radio to meet every person's wants, not needs, is an impossible task. The K4 is a bells and whistles radio. The everyday user or for that matter contester does not need half of the interface ability that the K4 will offer. For me I need a bomb proof front end for a high RF environment, namely SO2R on a city lot using the same antenna for 2 radios at the same time with band pass filters and multiplexers that offer 100db of rejection. To date no SDR only radio offers what a superhet offers. Until the HD model is implemented, the K4 is not the radio for me. If I were to be a one radio shack radio user and not 2 for SO2R, it would be my first choice. For instance, the IC7300 and IC7610, both are fantastic radios. Put another RF source remotely near them and the ADC is overloaded and the AGC pumps/attacks and you hear nothing. Both are a massive failure when using SO2R or at Field Day. The second thing that I need, being in a large city is the ability of the receiver to deal with intermittent noise problems. Line noise and the increased noise floor that highly populated areas hit the front end of a receiver has to be ameliorated by the receiver. Algorithms for noise blanking, and digital noise reduction and a tunable passband capability without ringing and loss of weak signal detection is what is needed. That is a tall order. Narrowing down the frequency by a superhet front end and adding band pass filters to help with this will cut the work of the ADC down due to the decreased spectrum that needs to be converted. Then the FPGA and DSP sections do not have to process so much data and this should speed up the response time and will add increased selectivity, hopefully. But until the HD is implemented this is not going to happen. What I don't need in a radio: I don't need 5 receive antenna ports. If I ever have more than one RX antenna, then it will be on a rotary switch or a button console that I can quickly rotate through to select the antenna for best reception. Faster and more contest efficient and way less cumbersome than that which is built into a radio with multiple button screen pushes. Only 1 Rx port is needed. I don't need remote ability. For the most part only a fraction of a percent of all ops use remote applications. The guys at RemoteHam are making a fortune using this technology. I am not a person that has $3000 to pay for a weekend of remote contest station operation. I don't need eye candy offered by high resolution output to a large screen. When I am running it offers nothing. It is the ability to separate the signals between the ears and a large screen does diddly for me. For S&P for the less skilled, yes it may be to some advantage, at least it gives something nice to look at the noise floor with. The ability of a narrow bandwidth capable screen for the Pan adaptor, eg, 1 or 2 khz is of far greater use to me. On a 7 inch screen I can see the weak ones easily. The micro pan is a nice idea but I would much prefer having half of the full sized pan to be 1 or 2khz wide and the other half 20 to 50 khz selectable. I would gang the receivers on the same frequency and use diversity RX and have a continuous large but easily selectable narrow screen without the addition of a separate monitor that is never placed ergonomically to the operating position. That way my eyes, neck and shoulders are looking at the radio face and I am getting the info that I need without glancing at another screen that is not eyes straight forward and level to the operating position. I don't need a CW decoder. The best one is between your own ears. If I were serious about digital modes I would not be using an in radio decoder. I would go with a 24 bit audio device and an outboard computer with multiple ways to simultaneously decode RTTY. FT8 and for the most part, all other digital modes are boring to me. I don't use them. PSK 31 for rag chewing is ok, but rarely do you find that any more, and after about a month, on PSK, you have already worked every one using that mode. You don't need a great radio for FT8. As long as the radio can be CAT controled you are good to go. Each operator has their own needs when it comes to operating. Mine are contest oriented. Strong bomb proof rx for high RF environment, brick wall passbands, excellent sensitivity, an agc that does not pump when a 20 over 9 signal is with in 500 hz of your passband, no ringing when filters are engaged, power line noise reduction at the push of a button, digital noise reduction for ambient noise,a notch filter that kills hetrodines or is tunable to get rid of a second cw signal in your passband and a price tag that I can live with because I need to buy 2 matching radios for SO2R. I was ready to buy a second K3S when it was discontinued in favor of the upcoming, and not yet released or developed K4. The K3S with second rx for diversity has been a wonderful radio for me and thousands of others. It has proven itself in high RF environments in many M/M M/2, SO2R and Dxpeditions. The only complaints I had were its noise reduction was lacking in ability and after about 10 hours the roar/harshness of sound got to me sometimes. There are a lot of great radios out there. Putting your finger anywhere in the top 10 will get you a great radio. It is a matter of operator choice and how much you are willing to spend. Having had $9879 on deposit to Elecraft for over a year and not so much as an email form letter thanking me for my interest free collateral that I extended to them for the usery, well, it did not leave a very good taste in my mouth. I own the KPA1500. It is a nice amp. The tuner is great. Easy to operate and interface. I plan to purchase a KPA500 to match my KAT500 to put in my travel trailer, but as for the K4, I have moved on. I wish you well Elecraft.

However, with a large hearing loss, you really need to find a solution that uses the hearing aids, as digital aids will have safety features and dynamic range compression that will minimise further damage to your hearing. You didn't mention which style you had. Whilst open fit would be common for people with good low frequency responses, I'm not sure that they would be used with that level of loss. I have full moulds, because I have an atypical loss in one ear, so I'm not sure of the limitations of open fit, but as they normally bypass the low frequencies, they may be unsuitable for a direct audio feed. I'm not sure to what extent that also applies to receiver in the canal. I suspect the direct bypass means they are less stable against feedback. For full moulds, and over the ear, I think you would normally get the options of electrical connections to audio shoes, induction loop, bluetooth (and 3.5mm audio) adapters that you wear on the body and send a very short range transmission to the actual aids. Some aids would directly support bluetooth. Incidentally, it may well not be well known, but hearing aid prescriptions generally under-compensate by about a factor of two in the dB values, so an aid for a 60dB loss would, typically, only have 30dB gain at the frequency in question. -- David Woolley On 26/01/2021 16:22, Joseph Shuman wrote: > I have severe high-frequency hearing loss, up to 85 dB at 6-8KHz and 60 dB at 3-4KHz.

My primary K3 sits next to my primary monitor with the P3 on the other side of the K3 and an external, separate monitor above the P3 for a lager waterfall, useful when chasing DX operating split. Flexibility and ergonomics are important elements of good shack design, especially if we expand the shack beyond one radio and a laptop. However, even for FD, I assert the laptop should be directly in front of the operator who should do the operating and logging with the radio within easy reach to the side of the laptop or monitor/keyboard. Rarely is there a need to touch the radio, even for changing frequencies/bands or modes. A second op can help and learn, but should not do the logging, regardless of mode. There is a big difference between six folks operating a radio for several hours and making several hundred contacts vs. one who makes 1600+ FD contacts in 24! The latter's fingers seldom leave the keyboard. Placing more than one "window", regardless of source, in a single monitor requires only a switcher with multiple inputs and the ability to send them in combination to a monitor. You may not have to buy a new monitor although you'll need to review specifications carefully to determine if a new monitor or a switch is for you. And, be ready to test the monitor, switch, and input devices! My Geochron will not work through a switch I bought although the TiVo will even though both work well directly to the two HDMI inputs on the TV, just one at-a-time. The reason remains hidden thus far with bigger fish to fry in the shack. 73, Bill, K8TE -- Sent from: http://elecraft.365791.n2.nabble.com/ From sm.shearer.01 at gmail.com Tue Jan 26 13:36:03 2021 From: sm.shearer.01 at gmail.com (stephen shearer) Date: Tue, 26 Jan 2021 13:36:03 -0500 Subject: [Elecraft] K4 Panadaptor Display In-Reply-To: References: <5ED9C0CC23C0B9E5@re-prd-rgout-002.btmx-prd.synchronoss.net> <5C9D716F-60EC-41DB-A308-373A6DC3B398@usermail.com> Message-ID: Mike, Good idea.

In-Reply-To: References: Message-ID: There are two windings on the PA output transformer: 1:1 and 1:4. We select one of these based on power level, battery voltage, and in some cases, operating mode. In the 1:1 setting, the PA drain impedance is 50 ohms, making it more efficient for at power levels, reducing current drain. In the 1:4 setting, the PA drain impedance is 12.5 ohms; the transformer steps it back up to 50 ohms for the low-pass filters. In this case it's more efficient at higher power levels, at the expense of higher current drain.

My hearing loss is not profound, but when I started using hearing aids I had to ditch my Yamaha CM-500 headset, as its over the ear style rubbed against the behind the ear receiver in canal style of my hearing aid. That made for a LOT of unwanted noise. I went to an on the ear headset and have been very happy. That might not do the job for someone with severe hearing loss because the mic for the aid is in the unit behind the ear. I use the Bluetooth capability of these hearing aids for phone calls and it is amazing how good it sounds... better than using the phone in a more conventional manner. My hearing aids do allow me to boost the high end, and I can adjust the levels between the right and left aid. These units are Phonak Audeo P90 units. I had to pay big bucks because they are not covered by any of my insurance. My brother-in-law just got a pair like these through the VA at no cost to him... he thanked me for paying my taxes. The option of piping your rig into your hearing aids might be the solution if you have that option.

My aids are Phonak Audeo as well - high priced devices that are behind the ear with receivers in the outer canal. I also use a Phonak CommPilot device with a loop that hangs around my neck and feeds signals to the aids by induction. The Comm Pilot is Bluetooth paired with my mobile phone for hands-free operation and has a 3.5 mm "Audio Jack" that permits me to feed audio from external devices with a suitable cable. The audio feels like it's inside my head, and the aids' primary function of boosting external sounds is reduced slightly but not eliminated. Batteries in the aids last about a week if disconnected while I sleep, and the CommPilot is put on charge at that time as well. Not much of a learning curve. Works well with my computer and radios. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From w4sc at windstream.net Tue Jan 26 16:30:24 2021 From: w4sc at windstream.net (w4sc) Date: Tue, 26 Jan 2021 16:30:24 -0500 Subject: [Elecraft] DB15HD cable sopurce Message-ID: <58.1F.13560.EE980106@smtp01.aqua.bos.sync.lan> A search on Amazon for ?Amphenol CS-DSDHD 15-pin? returns a list of fully populated 1:!, shielded M/F and M/M cables sourced by Amphenol in various lengths from 2.5 to 25 feet ( plus some others).

Several comments here. First, hearing "doctors" who sell hearing aids get a 100% commission for what they sell, doubling the cost to the buyer. When my XYL was looking for aids, several ham friends who also happen to be engineers, recommended Costco. I went with her to the appointment to check her hearing and prescribe aids, and I took the same evaluation as she did. I was also present when they "tuned" the aids she bought a few weeks later. As an audio professional, I had to learn a lot about human hearing, and I was VERY impressed with every aspect of the process. They used excellent instrumentation, and the people doing it knew what they were doing. AND -- Costco sells top quality aids without the 100% markup, so the cost is half of what we would pay to an audiologist's office. Second, the aids she bought (about $3K for the pair), can be programmed for multiple settings, which can be recalled and tweaked from an app that runs on her Android phone and on her iPad, but the iPad app is superior to the Android app. Third -- a good friend who has severe hearing loss asked for help setting his K3 to compensate. My advice to him was to set RXEQ for maximum cut of all bands below 1 kHz and max boost of the remaining bands. He reported that it works well for him. When doing these tweaks, I suggest varying the 1 kHz setting "by ear." Also, set the IF bandwidth for 500 Hz-3kHz audio bandwidth. Finally, I strongly recommend that Wayne build "hearing impaired" settings into K4 firmware. I'd be happy to consult with him on this. 73, Jim K9YC From donwilh at embarqmail.com Tue Jan 26 17:21:59 2021 From: donwilh at embarqmail.com (Don Wilhelm) Date: Tue, 26 Jan 2021 17:21:59 -0500 Subject: [Elecraft] MH2 mic and the K3 In-Reply-To: References: <1611684824870-0.post@n2.nabble.com> <2DD14D5A-2AAF-4250-9FAE-5CAF06F9EC87@gmail.com> Message-ID: <31b7a96f-411b-22b0-6df1-75d0c97b1646@embarqmail.com> I am sorry to disagree, but the MH2 will work fine for both the K2 and K3. They are interchangable. After the repair and configuration of over 1000 K2s, I am quite familiar with the K2 microphone configuration for various microphones. Yes, the K2 mic config header must be jumpered properly and have a bias resistor soldered between pins 1 and 6 on the rear of the mic jack, but once set up it will work. The original poster has his K2 set up to use that microphone already. Moving it to the K3 is simply a matter of setting the MIC SEL menu to FP L Bias. If the MH2 mic fails, the MH4 is a direct replacement. 73, Don W3FPR On 1/26/2021 4:34 PM, Clark Macaulay wrote: > Download the MH2 instructions from Elecraft site and you will see that the > mic has different jumper settings for the K3.

All I can say is, I can't wait to get mine! Question for Eric/the Elecraft brain trust - will we be able to use a USB WiFi adapter in one of the K4's USB ports, to provide network access? I can't get wired networking into my shack, and the thought of downloading firmware/updates to my computer, saving them to a USB drive, then downloading the new firmware/update into the K4 seems like too many opportunities to corrupt the firmware. Feedback - I'm thrilled to hear Eric expects the K4 kits to begin shipping in 3-4 months. Even if there are unforeseen delays and reality turns out to be 6-8 months, that is still sooner than I expected. Maybe I'll be able to order myself a late birthday present end of March or into April! Birthday is in late March, hint, hint! :-) Eric, thanks for the meeting.

I have had a K2/10 for about two years and enjoy using it as my primary rig for both CW and SSB. I have other QRP rigs and I really need a 100W transceiver, so I recently made the decision to upgrade my K2 with the internal KPA-100. I would also like to get the matching KAT100, but unfortunately the ATU is no longer available from Elecraft. Does anyone have a KAT100 sitting around that they are no longer using and would be willing to part with for the right price? My email can be found on QRZ.

I've been testing a pair of K4D (not HD) radios for SO2R (Single Op Two Radio) contesting at my QTH, which has one tower, closely-spaced monoband antennas, and 1500W output. I'm using Array Solutions 200W W3NQN Bandpass filters and Top Ten Devices coax stubs. There are two or more contest stations on the mountains above me (K6TD's remote, and W6NL) that are line-of-sight, and they can produce very loud signals, S9 +50 dB or more off the back of my beams. The front end of the K4D performs just as well, as far as I can tell, as the two K3 radios I used before, which had 8 pole crystal filters (the Inrad 500 Hz 8-pole crystal was my favorite). I've heard no "AGC pumping" or "desense" on the K4D, from either of these loud stations a few kHz away, though I can hear their transmitted phase noise, and see it on the K4 scope. I can transmit on one band and listen on an adjacent band, and though I hear my harmonics or IMD for neighborhood non-linear devices in certain directions, the K4D receiver doesn't "block" when I transmit on the other. As I've mentioned before, the K4D audio is a vast improvement over the K3 and K3S, which really helps when you're lucky enough to attract a pileup. The QSK is better too, which helps when you're calling in a pileup. Furthermore, you DO NOT need to tap multiple times to switch to the RX antenna, as seen in the recent live demo by WA6HHQ. What Eric did not get to demonstrate is that there is an ANT CFG menu option that allows you to select which antennas you want the RX ANT button to cycle through. When that option is selected, a single tap of the RX ANT button toggles the receiver between the TX ANT and RX1 antennas, say, instead of popping up a menu, so the K4D can work the same as the K3. You can also toggle an RX ANT in and out from the keyboard of your logging software, simply by sending a host command with a function key. Or you can cycle through multiple RX antennas with each tap. The same applies to the TX antennas. The 8 K-POD buttons can also be used to send host commands (or "macros") to do anything you can do with a button, or several buttons. The only time the K4HD model might be best would be when there are two rigs *on the same band*, such as at Field Day, or at a large DXpedition, or at a large Multi-Multi station with a RUN and MULT stations on the same band. And, as I understand it, the plan is that a K4D can be field upgradable to an K4HD model at a later date. What remains to be seen, though, is if the "ripple" in the roofing filters of the HD module introduces any pileup mush, which was one explanation for why the K3 and K3S still had some pileup mush, even after the K3 AGC settings and RF Gain were properly adjusted as recommended here . Time will tell. As of now, I haven't heard any pileup mush (RX IMD or Audio IMD) in the K4D. As for noise blanking and noise reduction, it's not something I can offer an opinion about, because I prefer to leave both OFF, as I did on my K3. 73, Bob, N6TV K4 Field Tester On Tue, Jan 26, 2021 at 9:15 AM Morgan Bailey wrote: > For me I need a bomb proof front end for a high RF environment, namely > SO2R on a city lot using the same antenna for 2 radios at the same time > with band pass filters and multiplexers that offer 100db of rejection.

There have been suggestions that: 1. You can?t do it, except by using a quadrant monitor which can accept say 4 inputs! 2. You can achieve a similar result by using the N1MM Spectrum Display! 3. You can do it with a bit of easily available splitter hardware! 4. You can achieve a similar result by using an SDR display with your K4! 5. You can maybe do it by using some additional software ? possibly the K4RV remote software currently in development? It seems to me that it would be a really good idea if Wayne or someone else from Elecraft could please clarify the situation and possibilities? For completeness, my original question was: I wonder if it is possible to show the K4 panadaptor(s) display as a separate floating window on the external monitor? So that for example you could have your logging program windows open as well as a separately floating K4 panadaptor display showing on the same monitor. 73 Ray G3XLG 73 Ray G3XLG From jim at audiosystemsgroup.com Wed Jan 27 05:10:45 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 27 Jan 2021 02:10:45 -0800 Subject: [Elecraft] You probably do not need a K4HD for SO2R contesting In-Reply-To: References: <6010130c.1c69fb81.2bc5e.3b76SMTPIN_ADDED_BROKEN@mx.google.com> Message-ID: <06bfad7e-1037-af06-18bb-f680104b04b5@audiosystemsgroup.com> Bob is a top contester, often operates from top contesting stations, and I strongly value his comments. I'm not far from Bob, or W6NL and K6TD's remote (both mountaintop stations, line of sight). Last I heard, W6NL is running Yaesu rigs, lots of phase noise and clicks; I don't know what K6TD is running, but I suspect Flex. W0YK and K6XX are very close by, both mountaintops. K6XX is VERY clean, only five miles N. We can work 500 Hz apart on CW, both running legal limit. YK and XX are also running K4s; I'm runing K3s with updated synth boards. 73, Jim K9YC On 1/27/2021 12:56 AM, Bob Wilson, N6TV wrote: > Old Subject line was: "K4 Panadapter Display" > > This is in response to the post by NJ8M, excerpted below. > > I've been testing a pair of K4D (not HD) radios for SO2R (Single Op Two > Radio) contesting at my QTH, which has one tower, closely-spaced monoband > antennas, and 1500W output.

Message-ID: Issue. Unable to undertake VCO alignment. Voltage at R30 fixed at 24mV. The VCO oscillator test (Alignment and test Part II p 63) has passed. Well the frequency is 7.98MHz rather than 8->10 but that conceivably could be within the bounds of measurement error. In the VCO alignment test a DMM (Keysight U1271) clamped onto the left side end of R30 reads 24mV no matter what the setting of L30. I have looked everywhere over the appropriate circuitry but can see no issues. Including triple checking T5 which is 100% wound and fitted properly. I made the measurements from troubleshooting (PLL Reference Oscillator and VCO P 10) and got:- Reference Oscillator Output 0.72 VCO Output 0.24 VCO Buffer Output 0.59 All measurements are at the low end of the acceptable range but just in spec. I measured voltages in the area and have noted the following:- 1. U4 (MC145170) pin 7 CLK/SCK is at 5v as against the specified 0v. 2. U4 pin 13 PDOUT is at 5v rather than 4v. This feeds the inverting input of U6B causing the output to be low. 3. The gate input of Q18 is 0 rather than -1. I am at a loss as to what to check next and any suggestions would be most welcome. BTW I also have a ? decent scope so can probe with that assuming I can figure out what I should be seeing. The K2 is a brilliant kit but seriously different to tube amps. which is my usual playpen.

I live in Western Washington, my locality has about the same total rainfall as the middle east coast states but we rarely have downpours. It just drizzles and mists all the time. I have owned boats in this climate and I know proximity to water greatly magnifies the problem. Electrical connections corrode quickly in a damp marine environment. I used to have to go through my boat wiring system and clean contacts annually to keep the lights functioning. A small heat source does wonders to lower humidity. Even an incandescent lightbulb can help in small spaces. Just running your radio generates heat that dissipates humidity within the radio.. I have a wood shop in an unheated garage. I have to keep a heat source in there in the winter to keep the tools dry, otherwise my tools will rust away. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of David Olean Sent: Wednesday, January 27, 2021 9:42 AM To: Joseph Shuman ; Elecraft Mail Server Subject: Re: [Elecraft] Shack Equipment Storage I would worry about condensation.

I'm not discounting the comments about moisture, but this is how we get socketed components slowly working their way out. You might want to open things up occasionally and make sure things are still seated, cables still fully connected etc. This will happen much more frequently in cold winters than in warm summers. 73, Dennis NJ6G On 1/27/2021 07:18, Joseph Shuman via Elecraft wrote: > There is a difference between stupidity and ignorance.

Anybody with an unheated workshop here in Maine knows the problem of a mild spell causing water to condense on a tractor that has been sitting in a 10 degree F. barn.? One answer is never to let your equipment get too cold, hence a heater, maybe even a heating pad under the K3? Another is to use a vapor barrier to keep the moisture out of the shack?? Maybe keep the equipment in an airtight chest?? This can get complicated and depends very much on local conditions, but deserves attention.

If I understand your question, the answer is "Yes, as you narrow the DSP BW with the 'WIDTH" knob, the roofing filters will switch such that the narrowest filter that still includes the DSP BW will be selected". To your second question, the ultimate BW is set by the DSP, and on my K3, that's 50 Hz.? It doesn't really matter what roofing filter is selected.? The xtal filters are in the 1st IF [8 MHz] and their primary [maybe only] purpose is to suppress strong signals outside the DSP BW that would activate the AGC and affect the level of the desired signal inside the DSP BW, even though you can't hear them.? It follows that you'd probably like the selection of roofing filters to follow the DSP BW as closely as possible.? You won't see any difference between your Rigs A, B, and C. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County > NJ Mike wrote: > > If I understand it correctly, as you turn the bandwidth knob > counterclockwise, the filter narrows.?

Right - I hadn't encountered any but I was so happy with what I heard on quiet bands that I couldn't refrain from commenting. Today I got on the 19Z CWT to give it a try. Unfortunately, I had some pretty bad local RFI. It sounded like arcing from an intermittent, loose electrical connection, possibly induced by recent high winds here, and made weak signals hard to copy. The K4 NB helped some but it wasn't the test I had intended ... unless you're looking for a report that the noise was quite audible while transmitting - it was. I almost gave up in disgust after 22 minutes but put the 'phones back on for the last 11 minutes of the event and was delighted to find the noise completely gone! So I did get in 11 minutes of a reasonable, single-band evaluation (20M). And it was good! QSK remained solid. There were a few low level artifacts I hadn't heard before, probably due to an amplified speaker at this location that I wasn't using but had not powered off. At 20Z the CWT ended, the band went quiet, and I did a little more transmitting to confirm that QSK on the empty band sounded no different than during the CWT. This was *not a comprehensive or conclusive test*, but it's very encouraging - the QSK did not degrade under these busier band conditions. I'll try to clean up my audio distribution setup and report any differences. 73, /Rick N6XI On Fri, Jan 22, 2021 at 11:43 AM Rick Tavan wrote: > I've had a chance to try the latest improvements to QSK on the field test > K4.

At a given RH, we know the temperature at which condensation occurs as the Dew Point. I agree with previous posts that increasing temperature (above the Dew Point) will prevent condensation and suggest that this is a lot easier in "drafty" volumes than is reducing the humidity. I have a very well insulated house in New England with an uninsulated drafty basement shack; somewhat better than a tent. I suggest that to prevent condensation in and on gear, it is simpler and more economical to just leave the gear on. Enough heat is produced, in my experience, and it is produced in the right place. We are not worried about filament lifetime in modern gear. Leaving a large Xcvr on consumes maybe 20-40W, while heating my shack 15F degrees electrically, consumes over 2kW. 73, Steve KL7JT From josh at voodoolab.com Wed Jan 27 16:54:57 2021 From: josh at voodoolab.com (Josh Fiden) Date: Wed, 27 Jan 2021 13:54:57 -0800 Subject: [Elecraft] Shack Equipment Storage In-Reply-To: <342743f9-904c-8237-0c8d-21b9ff330da8@metrocast.net> References: <4FC0D545-739F-4DEC-B50A-8CD639A3AE55@icloud.com> <342743f9-904c-8237-0c8d-21b9ff330da8@metrocast.net> Message-ID: These barn thermostats are inexpensive.

I have the 8-pole 250 Hz and 400 Hz filters, but I set the DSP IF for 500 Hz for RTTY. I'm well aware how similarly they measure -- W0YK and I did that independently in 2008-9 when we first installed them. 73, Jim From jim at audiosystemsgroup.com Wed Jan 27 19:15:10 2021 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 27 Jan 2021 16:15:10 -0800 Subject: [Elecraft] Roofing filters and DSP bandwidth tuning In-Reply-To: <89fd0159-cc4a-2acd-8ced-f162da8cd788@david-woolley.me.uk> References: <20210127141435.Horde.t2dPvz1smUcdhGaWDTHpCEj@www11.qth.com> <2278e644-d3f2-28b3-58bc-5c5e5599b622@foothill.net> <89fd0159-cc4a-2acd-8ced-f162da8cd788@david-woolley.me.uk> Message-ID: <2acbd172-f10d-4e5e-7b8e-3dca5c15d1c4@audiosystemsgroup.com> On 1/27/2021 3:06 PM, David Woolley wrote: > Having the roofing filter too close to the DSP filter is not necessarily > a good thing, as the roofing filters are likely to have worse passband > ripples and will have non-linear phase responses, which can compromise > digital modes.?

K1JT strongly urges 3kHz or greater IF bandwidths for his modes, and for exactly that reason. And it's why top RTTY contesters have abandoned the K3's dual-peak filter in favor of 500 Hz IF bandwidth. My professional life in audio system design taught me that speech intelligibility is degraded by time/phase distortion and suspected the result would be the same with RTTY, but I was derided when I started preaching that to RTTY guys. Several years later, author of the 2Tone RTTY software G3YYD said the same thing, and folks started believing it. It's also why I find that the 2.1 kHz 8-pole provides better speech intelligibility than the 1.8 kHz filter. Years ago, I tried using narrow SSB realignments of the K2's CW crystal filters in contests. I had carefully tweaked them per the build instructions, noting that their amplitude response looked like the profile of a mountain range. I wasn't surprised that those settings made signals much harder to copy. The SSB TX filter sounded fine on RX. When I switched from the 2.7 kHz 5-pole filters to the 2.8 kHz filters for TX in one of my K3s I noticed considerably less incidental AM on RTTY, and immediately converted the other two. I didn't do that in the 2nd RX, because I only use it for weak signal CW work on the lower bands. 73, Jim K9YC From mitchone at reagan.com Wed Jan 27 21:11:03 2021 From: mitchone at reagan.com (Mitch Johnson) Date: Wed, 27 Jan 2021 21:11:03 -0500 Subject: [Elecraft] Secure that AX-1 whip Message-ID: This is more of an amusing story than a warning.

Fix: (1) remove any lining to expose underside of the roof tiles (2) Spray 125mm (4") of polyurethane expanding foam over the tiles. This (a) locks the tiles & prevents any roof movement (b) keeps out any dust (c) warm in winter (d) cool in summer (e) reduces your heating costs. It is a recognised building treatment & several companies will quote for the work. Best done in summer as fumes can persist for a week or two. Final thought: if you can put in a velux double skin opening window in the roof with a 180 deg. opening ?? preferably near a chimney stack. You can then get at and mount antenna from a pair of steps through the window. You need to install the window before you get the spray.

Set humidity level between 40 an 50 percent. This is optimum for the gear as well as human comfort and, importantly, mold (mould) growth opportunity is greatly minimized. Our governments, the military and many independent research organisations have repeatedly found the optimum environmental conditions for human health and efficiency to be 68 to 72 degrees F or about 20 to 22 degrees C and a relative humidity of 40 to 45 percent.

However as I remember the Novice bands were a zoo, General class operators avoided us. A CQ could go on for several minutes but it was a fun playpen. Wow staying up to 2 AM could yield a QSO in Oklahoma all the way from Virginia on 40M. That was a QSO you could brag about. My surplus TCS rig would not go onto 15M so real DX was pretty much out for the first two months of my Novice ticket, then the General Class exam was passed and what a difference. They were good days but the chirp is well left in the past. Yes we need to return to the true path of CW, FT8 is a drug and makes many of us lazy, mea maxima culpa.

One day I was on and there were 3 or 4 other novices real close in to ?my? one and only frequency and so it was hard to make sense of all that, especially for a beginner like me then. But there was one guy who had a ?doh-wee? sound to his cw ? every dit and dah had a ?doh-wee? characteristic to it. Obviously not an example of a good signal, but that oddity was what enabled me to pull him out. I worked him as a result.

As his understudy, I've learned the names of the birds that hang out in our yard and gather at local wetlands. On a recent walk we saw one of our favorites, an American kestrel, a small raptor that terrorizes lizards and mice in the foothills on both sides of the San Francisco Bay. The bird's coloration is a surprising mix of blue, brown, orange, yellow, and white, adorned with an array of black dots. Finding a kestrel in the wild is like stumbling upon a rare gem, lying on the ground. The bird reminded me that when I was a kid, I often hunted for gems of a different sort: DX. I was a novice, and in the early 1970s, novices were limited to working DX Of The First Kind. CW. Like brightly colored birds, each CW signal arriving from a distant land was unique. Several factors were involved. In those days most ops used bugs or straight keys, so each operator had an identifiable fist. Rigs were not as stable as they are now, yielding timbres with a motley mix of buzz, drift, and chirp. Add fading and noise to the mix, and you had no shortage of audible intrigue. In fact -- trust me on this one -- RST reports haven't always ended with a dependable "9." I once gave out an RST of 332. I'll never forget that poor soul's chaotic whoop, best described as a singular blend of yodel and kazoo. Over time I became something of a CW pathologist, keenly aware of each station's affliction, including my own. These variations were useful. You could tell who you'd already worked. If you were a regular on the novice bands, you'd even get to know fellow travelers by their frequencies, since many, like me, were "rock-bound" -- slaves to a handful of crystals. VFOs were starting to make an appearance in novice gear...but see "chirp," above. Now, in 2021, the chirp is gone. CW signals still have many distinguishing traits, though. These include speed, keying weight, the operator's affectations and favored prosigns, and direction-specific propagation anomalies. Here's where we stretch the central metaphor to just about max. If randomly occurring CW signals on our bands are creatures of the wild, then...are FT8 stations the occupants of an urban zoo? Don't get me wrong: It's a pleasant place, with free tram rides, open 24 hours a day. The diversity of species is unprecedented. But imagine, on a given day, that you've sampled the zoo's exotic offerings, memorized the brochure, bought the t-shirt, and partaken of the sumptuous snack bar. What next? Take a walk on the wild side. Yank the cord and jump off the tram at an unmarked stop. Hop the fence. Work your way down the unpaved trail from the upper mesa to the open savannah, then sit on the ten-foot wall and dangle your feet over the edge. Welcome to the ecosystem of beings who are free to roam. They may be camouflaged, blending into the background.

In a net or roundtable [we did that on CW then], you knew who was currently sending just by their signal.? Other than some today with horrendous clicks, our signals are sterile and perfect.? Zero beating used to be an art, now just press the SPOT button.? I miss the personality of those old signals. The Windows API call to the MIDI interface includes a pointer to a table of codes, well over 100 of them, that define the particular "instrument" that will be played.? Select "Church organ" and by golly, the note sounds just like a pipe organ in a big empty room.? Since the K4 processor(s) are said to have nearly unlimited firmware expansion space, how about a small table with entries like: "2021 Perfect," "1955 new General with VFO chirp," "Not quite big enough caps full-wave hum," "Heath VF-1 Chow Pee Chow Pee", "Slow drifter," etc.? When you sit down for a few QSO's, you select which you'd like to be.? Perhaps Wayne can put that on the "To-Do after the K4 ships" list. ? Incidentally, the 50's ham bands, although a little drifty/chirpy/hummy, were nearly perfect compared to the marine CW bands.? Commercial Coastal, Navy, and Coast Guard stations were stable and clean, ships ... not so much.? Ships had DC power mains and used motor-generator sets to get the high voltages required by the transmitters.? It was common to use A2 emissions [MCW] particularly on the Holy Frequency and the MF frequencies around it. The TX chirped and drifted, the M-G set put a whine on the carrier which exhibited a slow chirp, the MCW chirped, none necessarily in the same direction.? Some of the carrier chirps would go all the way through your RX passband, you had to copy from either the front end or back end of the dits and dahs.? The entire ensemble sounded almost musical ... if you consider an elementary school band to be musical. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 1/28/2021 10:25 AM, Doug Turnbull wrote: > Wayne, > Nicely put and so true.

It's a much better way to spend New Years Eve than drinking. People bring out all kinds of old equipment and put it on the air. I have an entry in my log for a QSO with AE6C with the note, "SKN: running conar 1 tube to kpa500 + collins rx". And he sent me a old QSL to match, with a much younger photo of himself. The Conar was not not worth the 578 I gave him for tone, but charity is a virtue. I was running my K3 with a J-38 straight key.

I was amazed at the results of using the bone conduction headphones. My HF hearing loss is a result of machinery noise from the Submarine service with associated tinnitus. Basically I have 24/7 cicadas in my head, louder than normal speech volume. In my case, the conduction pathway apparently compensates for the tinnitus to a large extent so that speech under the band noise became much more discernible. On the down side, the conduction headphones were lousy for listening to Pink Floyd. Thanks to John and all who contributed.

I can call CQ on FT8 or SSB, not on CW. Sure, my K3 will send a perfect CQ via macro, indistinguishable from any other K3 sending a programmed CQ except the callsign. Problem is when someone comes back to me, if the decoder isn't working perfectly then I can't understand what's being said. That's definitely on me, and I acknowledge that. I'm at 177 DX entities on CW, all through the K3 and either in contests or Dxpeditions. In both cases I know who I'm calling, I know when they come back with my call and signal report, and I know which KPod or N1MM buttons to push to complete the exchange. Conversation? Not if my life depended on it. I'm over 120 countries on FT8/FT4 since Jan 1st and the pickings are getting slim. One JA or PY station is just like the other after a few thousand. With few Dxpeditions on the horizon and CW contests really not my cup of tea, yesterday I reached for the CW materials and plugged the key back in. It's time to do this on my own. Whoever runs across me calling CQ on CW will have heard a rare bird indeed. 73, Dennis NJ6G On 1/28/2021 10:11, Wayne Burdick wrote: > If randomly occurring CW signals on our bands are creatures of the wild, then...are FT8 stations the occupants of an urban zoo?

I took everything up to Level 3 (might take that someday), and have not regretted the time and effort at all. I'm retaining my code knowledge, and while I'm still pretty slow at receiving, my sending is serviceable. I lurk a lot and listen more than I send. I'm waiting for things to warm up, and hopefully become a little less restrictive, so I can take my QRP rigs back to the parks around here and do some operating. Maybe even activate a POTA park that's near my home! I wouldn't be able to do that if it wasn't for CW Academy. I've also heard good things about the Long Island CW Club. -=-=-=-=-=-=-=-=- 73, Gwen, NG3P On Thu, Jan 28, 2021 at 7:07 PM Dave W8OV wrote: > The next CW Academy class (Free) begins in April.

Funny you should mention this. I was working in my ham shack/shop this past Monday, with my brother doing some spray painting and afterwards, he sat down and looked for 40 meter contacts on CW. It was Monday night novice rig night apparently.? After dinner and a bit of TV with the missus, I went out to turn things off in the shack. My brother had left and kept all the lights and rigs turned on.? I sat down on 40 and watched the computer screen to see what came over the transom on FT-8. There was a QRP station in Cuba calling CQ. I set my power to 5 watts and called and called with no luck. Actually, I just sat there watching, and the computer did most of the work. After that episode, I decided I needed to do something a bit more interesting, so thought I should check out 160 meter CW before I shut the K3 off. I worked a few European stations with typical signal reports for a lackluster evening on 160.? I then saw RBN spots from Europe suddenly rise, so I tried a few CQs. I was answered by a rather weak but Q5 station from Russia. I answered him, but he did not return. A few more calls and he finally came back and gave me a very weak report. I had never heard this station before. I looked up his address after the QSO and was amazed to find that his location was just north of the border of eastern Mongolia. (Grid OO62!) He was about on the same longitude as Beijing, China!? Talk about a walk on the wild side! About 15 minutes later R8WF called me again and he was very loud and sent me a new report of 589! It was just after his Sunrise and the peak was awesome to say the least!? I am sure he was just as excited as I was to bag such an interesting QSO.? The direct path from me to R8WF is 360 degrees, or straight across the North Pole.? I am so glad that I had the opportunity to be there when the stars and planets had aligned so well. Such magic moments are treasured. Dave K1WHS On 1/28/2021 1:11 PM, Wayne Burdick wrote: > My son is an avid birdwatcher.

I'm older now but your stories remind me how much I've enjoyed amateur radio over all these years.. I'm gonna go home today and fire up the rigs. I grew in the early 60?s working from a dirt floor in a dug out basement of a suburban home working with very inexpensive and temperamental rigs. Making any contact was a cause for celebration. Maybe it's gotten too easy working with the newest rig technology. I guess that explains my continuing love for QRP.

I installed the IF Buffer amp in my K2 and feed it to an RSP2 and run HDSDR on the PC. When running HDSDR in IF mode, it makes for a very nice panadapter for the K2. I haven't messed with this for awhile and installed the latest version of HDSDR and was able to come up with the offsets necessary per mode for the point and click to be very accurate on the spectrum. An issue I'm having is that I would like to use the spectrum display in a "fixed tune mode" fashion similar to the P3. I.e. I set up the waterfall and spectrum windows for a 300KHz width for looking at 40m and would like to point and click on the signal of interest without the spectrum moving or sliding to the signal position I just selected. As it stands now, wherever the current signal selected is displayed in the spectrum, as soon as you select another signal, the entire spectrum moves to put the newly selected signal in the same location on the screen. I am able to get this function if I take the audio from HDSDR and use it with independent tuning from the K2. So, I'm guessing that the reset of the spectrum screen is due to linking the tuning with the K2 via OmniRig - but I'm not sure. I could swear I had this ability in the past, but it may never have been the case. I reinstalled an older version of HDSDR and it acted exactly the same. So, I'm wondering if anyone else has been down this road and knows of a trick that I have not found yet for doing fixed mode tuning while using HDSDR in IF mode synced to the K2. Even if this is not possible, this configuration makes for a fine panadapter for a K2 with the IF amp sold by DX Engineering. It is Jack Smith's, K8ZOA (SK) design and works nicely. 73, Dave, W8FGU From doug at dougfredericks.net Fri Jan 29 21:13:09 2021 From: doug at dougfredericks.net (doug at dougfredericks.net) Date: Fri, 29 Jan 2021 18:13:09 -0800 Subject: [Elecraft] KX2 and Accessories In-Reply-To: <387FE546-3250-4630-89EC-BDC35BF13D2D@dougfredericks.net> References: <387FE546-3250-4630-89EC-BDC35BF13D2D@dougfredericks.net> Message-ID: <18C5CE06-3EE1-4D4D-A431-E46BCC1EAF46@dougfredericks.net> Sold > On Jan 26, 2021, at 10:04 AM PST, doug at dougfredericks.net wrote: > > Hi, looking to sell my KX2 setup to fund a KXPA100+KXAT100. > > Includes "Shack in a Box" + the KXPD2 paddle + the KXUSB cable.

Lately I've been using my new hearing aid interface as a headphone accessory for my K-3. It is a small box (Phonak brand) that plugs into the K-3 headphone jack, and transmits the audio to my hearing aids via bluetooth. Works great - I enjoy listening to the bands, direct to my ears, without bothering the household, and avoiding some local noise interference. BUT - when I send CW, the sidetone is absent (and denies me the ability to listen to my transmission). This makes no sense. The sidetone is very present when I use regular passive headphones, or the K-3 speaker, with no adjustments to other settings. As soon as I plug the Phonak in, the sidetone is gone. All other receiver audio is coming through just fine. The problem occurs whether I am using straightkey or paddle. I'm assuming there's some kind of active voltage coming from the Phonak into the headphone jack but why does it only affect the sidetone? Reaching for the schematic...

That is not unusual, what is new is the way it connects.? Instead of simply plugging on there are a few threads so the adapter is firmly attached if needed.?

It seems ok when first switched on but once warm (after maybe 30-60mins) the rx can die. It may seem ok but tuning around causes either complete failure or intermittent failure on certain frequencies. Attempts at recalibrating the synth using VCO MD results in an error, typically ERR VCO 005. If the fault is intermittent and I tap DISP to view PLL volts, and then tune around the volts will be ok and then drop to zero on frequencies where the synth dies. I emailed elecraft support about this on 21 Jan but no response. I raised a query on the tech support page on 25 Jan, no response yet. It looks like neither old synths nor new synths are available. I'm about to pull the rig apart but has anyone any advice before I do that.

That is not unusual, what is new is the way it connects.? Instead of simply plugging on there are a few threads so the adapter is firmly attached if needed. This is the adapter that broke off in my Kenwood TS-830S. I had figured Sony = solid construction, but not quite so. It didn't take much tugging to snap it off. I had used it with other more modern 1/4" jacks with no problem. I think that it is a quality adapter for today, but I suspect that the Kenwood jack is simply stronger stuff. The internals of the Sony adapter are plastic, and simply snapped when I tried to remove the adapter. I then purchased a U-Green adapter...not sure if it will be the same, but I will likely insert it and leave it there. I still have my older headset with the 1/4" plug, but I prefer the newer Sony sets, and that way I can simply plug the 3.5 mm into the adapter. It occurred to me after I reassembled the Kenwood (disassembly to remove broken end) that there may be corrosion on the jack that causes sticking. I didn't note a loss of sound quality, but after all it's just limited bandwidth audio. ~R~ 72/73 de Rich NE1EE The Dusty Key On the banks of the Piscataqua From k2vco.vic at gmail.com Sun Jan 31 10:15:46 2021 From: k2vco.vic at gmail.com (Victor Rosenthal) Date: Sun, 31 Jan 2021 17:15:46 +0200 Subject: [Elecraft] K3 synth / PLL faulty In-Reply-To: <6016994C.1060401@g3tct.co.uk> References: <6016994C.1060401@g3tct.co.uk> Message-ID: The first thing to do when anything seems weird about the synths is to check all of those little cables. Make they are all well-seated, and push the connectors in and out a few times to clean off any corrosion. 73, Victor, 4X6GP Rehovot, Israel CWops #5 Formerly K2VCO https://www.qsl.net/k2vco/ On 31/01/2021 13:49, Graham Kimbell wrote: > My K3 (old synths, ser1198) has for a few weeks had an intermittent fault where the main rx synth loses lock.

KD5ONS - In the footsteps of Napoleon, the shadow figures stagger through the winter Falling back before the gates of Moscow, standing in the wings like an avenger And far away behind their lines, the partisans are stirring in the forest Coming unexpectedly upon their outposts, growing like a promise You'll never know, you'll never know, which way to turn, which way to look you'll never see us As we steal into the blackness of the night you'll never know, you'll never hear us And evening sings in a voice of amber, the dawn is surely coming The morning road leads to Stalingrad, and the sky is softly humming
