Check inside for any loose connections (weak battery holder springs for instance) or power wire terminals that may be partially unplugged. If you can't locate anything, an email to support may give you some other points to check. 73, Don W3FPR On 9/1/2019 11:49 AM, Sean Cunningham wrote: > Hi - > > I having been trying to find QSOs on 20m this weekend on my kx3 and AX-1 > > I have tried both with fully charged NimH AA batteries with power set to 5W > and with an external battery with power set to 15w. > > On a few occasions, my kx3 has turned itself off.

I think it was more to make it harder to exceed 1 kW input on CW. It is almost always possible to load an amplifier (with the usual PI network) for efficient operation at less than maximum output. It just has to be loaded lightly and not driven too hard. That conflicts, however, with the usual procedure of loading for maximum output. Also, with two plate voltage settings you could usually tune for maximum output at the low setting at about 1 kW input, and it would be tuned about right for 2 kW at the high setting. This reduced the stress during tuning, and probably was the most common strictly legal way to tune for 2 kW PEP input in those days. Actually, legally tuning for 2 kW input in those days was tricky. Collins used a bridge which compared RF input and output voltages and allowed tuning at low power. I used that circuit in an amplifier I built about 50 years ago, and it worked pretty well. A PI network in a tube amplifier allows properly loading the amplifier into a range of load impedances, but the operator or autotuner is looking at grid current, plate current, input/output voltage ratios, etc. to get the tuning right. This sets the tuning for efficient, linear operation. A solid state amplifier and ATU work very differently. The amplifier is designed to operate properly into a 50 Ohm resistive load, and the job of the ATU is to make the actual load as close to that as possible. One result of that is that a rather small mismatch can have a large effect on efficiency and/or linearity. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From n4zr at comcast.net Sun Sep 1 16:44:46 2019 From: n4zr at comcast.net (N4ZR) Date: Sun, 1 Sep 2019 16:44:46 -0400 Subject: [Elecraft] KPA-1500 on digital modes In-Reply-To: <6a62be28-6cd7-1a9c-5eab-f1b3e336c2fa@sdellington.us> References: <614f4cd9-dd09-d4aa-3e49-89169f0f760d@roadrunner.com> <90cadcae-59da-c5a9-9124-edceb379a3b7@sdellington.us> <979eeba1-2735-2cd3-15cf-9aeb50458b37@audiosystemsgroup.com> <01302794-1236-ea1e-97d6-8e3420cd4149@audiosystemsgroup.com> <6a62be28-6cd7-1a9c-5eab-f1b3e336c2fa@sdellington.us> Message-ID: FWIW, one of the things I like best about my KPA-1500 is that you can use its antenna tuner with the amp on Standby 73, Pete N4ZR Check out the Reverse Beacon Network at , now spotting RTTY activity worldwide.

I had intended to run my 2m 1500w amp at 600w for SSB (to be kinder and more linear), while running JT65 at 1300w which is where saturation begins. 1385w RF: 37A x 47.2V = 1746w (disp = 361w) 600w RF: 25A x 48.5V = 1212w (disp = 612w) http://www.kl7uw.com/test2.pdf MRF-1K50N disp = 2941w at 25c (derate above 25c) https://www.nxp.com/docs/en/data-sheet/MRF1K50N.pdf But average current draw in SSB is less than JT65 (which is keydown carrier). So I guess it depends on how long-winded your SSB talking is. Typically voice duty cycle is 20% at max whereas JT65 is 50/120 seconds = 42% Fortunately, I have a thermistor on the RF deck to monitor temperature with a digital voltmeter. Control board illuminates "overtemp" lamp at 43c and 50v is shutdown at 55c.

Bob, I'm curious to know how well that feature works. Let's say your KPA500 is STBY, your K3 is set to 100 W out, and you are transmitting in a digital mode. What happens when you switch the KPA500 to OPER? If you don't know the answer please don't it! My controller ensures that the KAT500 key line is inhibited when the KPA500 is in STBY. When the KPA500 goes to OPER I set appropriate exciter power, and only when correct power has been verified do I enable the key line.

The op has to set the K3 so that the power is controller per-band. When the KPA is switched to OPmode, it sends a message to the K3. The K3 then switches to the amplifier selection for power, which the op has et specifically for the KPA. The converse is also true, switching the KPA to STBY also sends a message that causes the K3 to realize the KPA?s state and move back to its main power setting for the band. Note that the power level is set for each band for both normal and KPA drive levels. This is well documented in the KPA manual and also in the K3 manual(s). 73!

Normally 100 watts.?? When the KPA500 is then switched to OPER the PWR on the K3S is set to the value as defined in the PWR SET menu.??? Typically 20 watts drives the KPA500 to 400 to 500 watts output.?? Thus there are 2 sets of per band power settings, one for barefoot operation and one for use with the amp. As to how well it works, I'd say 100% as I have observed no mis-operation or fault indication in the 2 years of using the station on a daily basis. 73 Bob, K4TAX On 9/2/2019 8:58 AM, Andy Durbin wrote: > "With my K3S, when I switch the KPA500 to Operate, the transceiver is automatically reduced to the correct power to drive the amp." > > Bob, > > I'm curious to know how well that feature works.

I *DO* suggest that you also set up the amp input/output for *ALL* bands, in particular the bands where the power limits are much lower (60M for example, 100 watts ERP compared to a dipole) so if you fail to recall as you change bands, you don't accidentally exceed limits with the amp in operate mode.

With the amp in standby, the power out up to 100 W is determined by the power setting (knob) on the K3. With the amp in operate, the (reduced drive) power is determined by the power setting on the K3; best if the 'Set by band' feature is used (the amount of drive for the desired output varies according to the band in use). You use the _same_ knob for operate/standby, it remembers.? It can't be simpler.

The issue is timing. Your code has to poll to determine the KPA op state, then start all the transitions which will result in the PTT line being negated. There are a lot of delays involved here. With the K3/KPA, the button press causes the KPA to send the mode change data to the K3 immediately. We wait until the data transfer is complete before starting the actual mode transition. By the time it is done and the KPA is ready to go, the K3 has processed the message and switched to the alternate (KPA) power level. By the time the K3 has displayed the KPA mode change on its display it has already made the change internally. Now realistically will anyone see a difference between the two methods? Probably not. The only real way to tell would be to start sending a CW message then tap the mode button to move the KPA to OP mode during the transition. Both methods will pick up the change, but the built-in method will do it slightly faster because of its advantage with not having to poll for the mode state change over the serial port. Nice job with the controller, by the way. I look forward to your write-up. 73! Jack, W6FB > On Sep 2, 2019, at 9:46 AM, Andy Durbin wrote: > > "It works very well.

Your code has to poll to determine the KPA op state, then start all the transitions which will result in the PTT line being negated." No, not true. There is no timing issue with my implementation since the key line is ALWAYS inhibited while KPA500 is in STBY mode. Required conditions have to be met before the key line is enabled. Any delay due to my slow system interfaces simply means that it takes a bit longer for the KPA500 to be set to OPER power level. Thanks for the explanation of the KPA500 K3 power control interface. The driver for doing a write up of my controller will probably be my club's presentations manager. He has twisted my arm a few times to prepare and give presentations and I'm probably due for another turn in the barrel. 73, Andy, k3wyc From johnae5x at gmail.com Mon Sep 2 14:51:54 2019 From: johnae5x at gmail.com (John Harper) Date: Mon, 2 Sep 2019 13:51:54 -0500 Subject: [Elecraft] It's no KX4 but...

It ignited countless fires and caused sparks to spew from telegraph machines, shocking their operators. It also created a dramatic show of aurora borealis, or northern lights, as far south as the Caribbean. Solar storms occur when enormous bubbles of superheated plasma are periodically ejected from the sun. Scientists believe that if a similar solar storm were to happen today, it would cause catastrophic damage by crippling power grids, satellites, GPS, and communications systems. Such an event could leave North American without power for months or years and could carry an economic impact as high as $2 trillion. While conducting observations from his private observatory outside of London on the morning of September 1, 1859, British amateur astronomer Richard Carrington noticed patches of intense white light erupt from the sun. The eruptions lasted about five minutes before dissipating. Little did Carrington know the flare he observed sent solar wind shock waves carrying supercharged plasma racing towards the earth. Hours later, those particles slammed into the earth?s magnetic shield, creating auroral flashes and clouds in vivid colors of red, violet, pink, and green. This single solar storm carried the energy equivalent of 10 billion atomic bombs and is known as the Carrington Event.

But there are major differences between the KX2/KX3 and '705 for those doing lightweight outdoor operation: - KX3 is half the size and 33% lighter; KX2 is one-third the size and weight - KX3 has max power out of 15 W, KX2 12 W (vs. 10 W); KX2 can put out 10 W on internal battery - the KX3/KX2 LCD is very high contrast, easily readable in bright sunlight (I've seen the '7300 display in sunlight, and it's almost completely washed out) - both KX-line rigs have a built-in wide-range ATU (not mentioned in the '705 brochure) - both work with an attached keyer paddle - both have far lower current drain (0.15-0.25 A vs. estimated 0.8-1.0 amps) - the '705s internal battery is only 2 AH/7.4 V = 14.8 WH; the KX2's is 2.5 AH and 11 V = 27.5 WH, and the KX3 can be used with 8x Lithium AA, 3A @ 12V = 36 WH The other head-scratching design choice is the lack of any sort of tilt stand for angled use. If you use it as shown on a desktop, with the display at 90 degrees and no feet, it will be very hard to push buttons, and when you do, the rig will slide backwards. If you place it on its back with the display facing up, operation would be awkward in many field situations. Hand-held operation also seems unlikely (something you can easily do with a KX2 or even a KX3).

If you use it as shown on a desktop, with the display at 90 degrees and no feet, it will be very hard to push buttons, and when you do, the rig will slide backwards. If you place it on its back with the display facing up, operation would be awkward in many field situations. Hand-held operation also seems unlikely (something you can easily do with a KX2 or even a KX3). Another question is whether the IC-705 will support full duplex operation (e.g. UHF/VHF) that satellite operators need for working linear and FM satellites. I?m not aware of any current field radio that does UHF/VHF full duplex. Most satellite operators typically end up using two radios for linear satellite contacts which adds complexity and bulk. A second question is how it might work as a mobile rig. It isn?t clear from the photos I?ve seen whether there is a mounting arrangement that would work well in a vehicle. The fact that the new model is a ?705? suggests a connection to the IC-706, which works well as a mobile rig with an easy-to-mount control head and a base that provides 100 watts. One has to wonder if Icom will eventually provide for the IC-705 a 100 watt HF option or a UHF/VHF option as an external amplifier for mobile use. FWIW.

And...there is little doubt that it lacks the advanced exotic capability to do really really hard things like operate its iambic keyer in mode A. I've never found an Icom rep even at Dayton who could explain why that was impossible technology for Icom, other than blame it vaguely and stupidly on "the engineers". That's if I was lucky enough to find an Icom rep at Hamvention who even knew what I meant when I asked about "iambic mode A". The other IC-705 characteristic that is adverse to outdoor operation is its very dark color scheme.

To most, if not all, of these guys, QRP mean slow output power. OK, great, as far as it goes, but you?re right. Whereas Yaekenlincowood just create what amounts to a low output power version of something else they already have more or less, Elecraft takes the whole design into consideration. If you don?t believe, and who here doesn?t, just look at, as one metric, current draw on receive. OK?is that really power efficient? Even the Chinese designs like the Xiegu X108/X5105/G90/G1M have pretty high current draw, relatively speaking, and they were never designed with QRO counterparts. Elecraft works hard to optimize the whole design, taking into account use cases for QRP, many of which will involve outdoor use with extended power requirements away from commercial electricity. Iteally matters. OK, every design has compromises, but I think Elecraft is very mindful of which compromises are acceptable to the end goal.

Most will go to 12 watts on 40 and 30 meters with an adequate power supply voltage while few can achieve 15 watts on all bands. There is nothing specific to the KPA100 option that would cause low power output from the base K2. However, there are a few things to check. First check the value of R98 on the bottom of the board. The normal value is 270 ohms, but after the addition of the KPA100, some experienced power oscillation due to the added RF Gain, and that value may have been increased to damp the oscillation. Then check to make certain T4 was not wound for "greater efficiency at 5 watts" with a 2:2:1:1 ratio instead of the normal 2:3:1:1 ratio - count the number of white turns on T4. That 'more efficient' T4 is actually less efficient above 5 watts and should never be used with the KSB2 option or the KPA100. If there is also HiCur as well as low power then the problem is either with T4 or the Low Pass Filter. Make certain the power supply leads are tight and large enough to keep the voltage drop low - a power source with at least 13.8 volts should be used and the voltage should not drop below 12.5 during transmit. 15 watts is not possible with a lower voltage, and the output on 12 and 10 meters may be less. 10 watts or more meets specification. If those checks do not provide the answer, then he will have to do the "Transmit Signal Tracing" in Appendix A of the manual to identify the first stage with less than the expected RF voltage output. 73, Don W3FPR On 9/4/2019 6:47 AM, Petr, OK1RP/M0SIS wrote: > Hi folks, > > my colleque got as birthday gift from family the K2.

A white (or very light) object will simply absorb much less heat ... all.day.long.?? And it will still be able to reradiate heat.? Just not as effectively, but it wouldn't need to. A dark object wouldn't be able to radiate its considerably greater absorbed heat until the sun went away, and by that time any potential damage would have been long done. I have a low slope roof behind parapets sealed with white elastomeric roofing coating.? I can walk barefoot on it all day in the June Arizona sun and it barely feels warm.?

Other equipment need only be certified by the manufacturer that it meets receiver RF leakage requirements and does not receive an FCC ID number.

Just picture a normal BNC "T", but with the male end swapped with the one of the female ends. What makes this useful is that with the male end plugged into your K2/K3, a right female points up for your loaded whip, AND the other female, straight across from the radio's connector can have a BNC to two pole banana adapter for easy connection of a counter-poise or ground wire. Another great use is for a scope probe connection. The probe attaches to the straight thru terminal with a right angle (down) jumper to say, a frequency counter sitting on top the scope. This can be accomplished with a normal BNC "T", but with both the probe AND counter connections at right angles to the scope itself, it's to say the least awkward. I can supply these at $10, shipped anywhere is the US. 73, Charlie k3ICH From gregg.w6izt1 at gmail.com Fri Sep 6 17:36:14 2019 From: gregg.w6izt1 at gmail.com (gregg.w6izt1 at gmail.com) Date: Fri, 6 Sep 2019 21:36:14 -0000 Subject: [Elecraft] OT SDR-14 Win 10 USB driver help Message-ID: <017401d564fb$1c7cfda0$5576f8e0$@gmail.com> I recently updated my FTDI drivers to support a new FTDI USB device that I added to my station.

(For example, if the device is plugged into a USB 2.0 port, try a USB 3.0 port, or vice versa). Wait a few seconds and with luck you may see a quick popup message saying that Windows has loaded the driver and the device is ready for use. I had a similar problem a couple of days ago on my Windows 10 Pro computer. The external USB audio device I use for data comm showed up fine in Device Manager and all the drivers showed as current and working.? Yet, WSJT-X and other software triggered a popup message that they couldn't connect to the device. Switching ports fixed it.? After that, I put the device back on its original port and the "loading driver" message popped up again and its working fine where it was. If my suggestion doesn't work, you may need to uninstall and install again.? I wanted to avoid that because my external device also operates four USB-to-RS232 comm ports and they are always a pain to reload and fix the comm port assignments. 73, Steve W4FMD On 9/6/2019 5:36 PM, gregg.w6izt1 at gmail.com wrote: > I recently updated my FTDI drivers to support a new FTDI USB device that I > added to my station.

What has happened is that when I put the amplifier into OPER, the received signal strength drops by several S units. It transmits normally and also receives normally in STBY. The issue occurred when I was changing rigs to use with the KPA500. Specifically I connected a Ten Tec Omni 6 but I cannot see how that could have caused the issue. However, the KPA500 now exhibits the same issue with my TS990 which it never has before. I believe that some considerable time ago, I did experience a similar situation and after reading all the manuals etc I found a way to resolve it. However, I have read the manual until I am blue in the face but I cannot find an answer this time. Of course I may have initiated a fault in the KPA500 but I would be surprised as it has taken all the mistakes I have thrown at it over the years and it has not so much as blinked. Any suggestions on how to sort the issue out, or what damage I might have caused to the switching circuitry, would be appreciated. Thanks in advance.

I currently have a Raspberry Pi 3B running Raspbian and Node Red. This allows control and monitoring of equipment in the shack, including the KPA1500 amp. This allows easy remote operating. Node Red acts as a web server and accessing from any browser allows control and monitoring of the station equipment. I currently have it set up with the following: KPA1500 via Ethernet Yaesu G1000dxa rotor with Idiom Press card and communicating via PST Rotator Flex Radio 6600 Data Loggers Web Switch Pro 8 outlet power strip to turn equipment on & off This is a work in progress and for the KPA1500 I only included the functions I need remotely. I only use the tuner on 75 meters and I preset the tuner programming across the band so when the radio QSYs it will have the tuner preset. I also only use antenna port 1 as I have an external antenna switch. You can always add more functions. Node Red also allows for connection of USB to serial cables so you can control devices with serial ports too. I thought this may be of interest to some on the mailing list. Since the mailing list does not allow attachments I have uploaded a screenshot of my Node Red as viewed in a web browser. On a Smartphone each column appear vertically with left column on top so you just need to scroll down on phone. https://www.dropbox.com/sh/01ip9df6fotumw4/AABYNL7cy06mwfY5Jw1BektAa?dl=0 I have also created a folder for each "Flow" in Node Red (KPA1500, Rotor, Vita49 and FlexRadio, and WebSwitch. I have uploaded the actual export from my programming in case anyone wants to play. You would install Raspbian on a Pi then install Node Red. Once installed you can import each flows content into a new tab in Node Red. See below for links For the KPA1500 I set it to a fixed IP address on my network. Same with the radio and DLI Web Switch and PC running PST Rotator. Here are some links Node Red https://nodered.org/ My Flows for Node Red KPA1500 https://www.dropbox.com/s/shhe6zhq3p3zszq/KPA1500.txt?dl=0 DLI Web Switch Pro https://www.dropbox.com/s/3og6ip94m836huy/DLI%20Webswitch.txt?dl=0 PST Rotator https://www.dropbox.com/s/mdefmcm1qkgjq12/rotor.txt?dl=0 FlexRadio https://www.dropbox.com/s/mhlz782f759lqjz/Flexradio.txt?dl=0 Vita49 https://www.dropbox.com/s/nwhay3mysvjrqpw/Vita49.txt?dl=0 DLI Web Switch Pro website https://www.digital-loggers.com/lpc.html I hope this is of use to those who run their station remotely or are planning to.

What has happened is that when I put the amplifier into OPER, the received signal strength drops by several S units. It transmits normally and also receives normally in STBY. The issue occurred when I was changing rigs to use with the KPA500. Specifically I connected a Ten Tec Omni 6 but I cannot see how that could have caused the issue. However, the KPA500 now exhibits the same issue with my TS990 which it never has before. I believe that some considerable time ago, I did experience a similar situation and after reading all the manuals etc I found a way to resolve it. However, I have read the manual until I am blue in the face but I cannot find an answer this time. Of course I may have initiated a fault in the KPA500 but I would be surprised as it has taken all the mistakes I have thrown at it over the years and it has not so much as blinked.

Try a good stiff power source - not a wall-wart. If the power source cannot provide the current required at the voltage required, then you will still hear a relay click as the P3 tries to power up, but the current or voltage from the power source drops significantly. If you are powering the P3 from the AUX DC jack on the K3, and you have an early K3, the current is limited to 0.5 amps before the resettable fuse opens and is barely enough for the P3, especially if it has the SVGA option. 73, Don W3FPR On 9/7/2019 8:23 PM, n1ix at n1ix.com wrote: > I bought a used P3 from an estate.

If setting SPKRS+PH to yes and still no audio, try tapping 1 while in that menu to toggle the sensing between early (+) or later boards (-)that had reverse polarity. If still no audio (in speakers only), then probably a bad audio chip U1 on DSP board.

The most likely problem is misalignment of band 2 of the KFL1-2. Perform a realignment of the 20m portion per the K1 manual. Don't waste too much time optimizing the settings of the KFL1-2 for maximum receiver sensitivity. The same inductances must be adjusted for maximum transmitter power output, and those adjustments are far far more critical. OR...for a direct simple shortcut, put the K1 on 20m in TUNE mode and peak L3, L4, L7, and L8 for maximum power output.

See the K1 manual for the adjustment procedure. If that does not bring the output up to at least 5 watts (when using a 13.8 volt or greater power source), then suspect the 22MHz crystal used for the 20 meter mixer. 73, Don W3FPR On 9/9/2019 9:14 PM, LL wrote: > I recently bought a two-band K1, s/n unknown.

Is it possible to manually adjust anything other than the position of the notch filter on the K3S. I recently was working FT8, when a ham relatively close to me was desensing my receiver when working FT8 on the same band. I was able to notch him out by manually setting the filter, but it seems like a pretty wide notch, especially for FT8, and was wondering if it was possible to adjust the width of the notch. I didn't see anything in the manual regarding adjustment of the width.

You are forgetting the resources required to do that - there is still work to design the kit, test it, and write the assembly and test instructions. Firmware would have to be re-written to remove the band switch to 60 meters. Then when all that has happened, write the BOM documents and the ECO. Board design is only a small part of the total required effort. I am certain all available Elecraft resources are being absorbed by "putting the wrappings on the K4", and there are none available to do those tasks. Even though the same board could be used, it is still a design effort to release such a kit. For those experimenters who are enterprising, I am certain they could "roll their own" - and maybe even could use the raw K60XV board from Elecraft as long as stock is available. The part of the K60XV schematic to add just the transverter interface parts is easy to extract from the K60XV schematic. If you don't know how to follow a schematic, a bit of learning may be required. 73, Don W3FPR On 9/11/2019 5:18 PM, Bill Coleman wrote: > Here?s a radical idea.

Manufacturing and distributing hardware, whether pre-assembled or in kit form, takes a LOT of work. Check out this video from Dave Jones at the EEVBlog on the economics of manufacturing your own hardware: https://youtu.be/UwrkfHadeQQ There's also a long thread on his forum: https://www.eevblog.com/forum/blog/eevblog-887-the-economics-of-selling-hardware/ I strongly recommend Dave's Youtube channel and his forum for information about electronics. If you're in the industry, maybe you've already run into it. I hope the video I linked helps clarify why it's not just a matter of putting out a kit or product "without the 60m parts". (I wouldn't even want to know the product liability side of distributing a product missing some parts because they're no longer available. That sounds like a lawsuit waiting to happen.) 73, Gwen, NG3P (who in no way works for Elecraft, and is just putting in her 2 cents worth) On Wed, Sep 11, 2019 at 6:21 PM Bill Coleman wrote: > Here?s a radical idea.

They DISCONTINUED the K60XV because they could no longer obtain the bottom-adjustment trimmer caps. Wayne suggested someone could design a new board that just had the XV part of the kit.

(I also have a Buddipole for remote operation.) Given that you can never have enough antennas, what should I add?? My situation is perfect, with no houses except mine around, no power lines, and plenty of space. Here's my thinking at the moment: 1.? I already have a new G5RV that I could probably string between some really tall trees to give me a dipole perpendicular to the one I have.? Need a launcher, though. 2.? I love to climb, and the kid in me would put up a 250' tower on the hill behind the house, but my wife keeps showing me articles about friends dying when they fall off roofs.? And I'm not excited about putting a lot of metal in the air at our historic farm, anyway.? A mono-pole might be OK. 3. We have a barn connected to the house with peak at about 35 feet (that's where one end of the G5RV Jr. is attached.)? It would be easy to put something against it, say a mast with a hinged anchor mount on the ground, then attach a line up 30 on the mast and pull it up from inside the barn.?

Never saw the rig doing it before. The actual current consumption didn?t change but the readout of the K3S only. That approx. +1,3 A also was noticed on transmit. Checking the circuit diagram I see a 0,005 ohm current sense resistor (R3). The voltage drop goes into a current sense monitor ((U6) and finally into a multi/demultiplexer (U6.1). As I already had a bad (=oscillating) op amp in the temperature readout circuit I wonder if bad luck struck twice and I got a bad current sensor or multi/demultiplexer? Now as the radio ran for a while and warmed up I don?t see the jump in the current display anymore. 2. not really an issue but maybe a software fix is possible the Noise Gate level is very much on the edge. With the handmicrophone and in particular with a desk microphone the mic gain level has to be set very carefully on the conservative side. That is the mic gain has to be set just at the point where the signal becomes a little bit weaker compared to the asymptotic setting where a maximum is reached and no increase possible anymore even though there is still headroom in the mic gain range (received on a remote SDR). However even with mic gain just set under the maximum permissible value and the Noise Gate level set to max (25) still an occasional popping can be heard by pushing and holding the ptt but no ambient noise. If the mic gain level is set to the permissible limit (ALC deflection) the noise gate doesn?t work anymore and an high frequent noise is coming along with the signal. No it is not the fan of the powersupply as I ran the station on a convection cooled linear powersupply and everything else in the shack muted. I even switched off the fan in the K3S which I normally leave running on "1". The compressor setting has NO effect at all on the point where the Noise Gate releases. The question is whether it is possible to have the firmware changed for more headroom in setting the Noise Gate level as the range from 0 to 15 is almost useless. 73/Roger - DL5RBW From donwilh at embarqmail.com Fri Sep 13 16:42:27 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Fri, 13 Sep 2019 16:42:27 -0400 Subject: [Elecraft] Low activity In-Reply-To: <77dc272f-0f4d-c4c9-da2b-b1834ae74970@bates.edu> References: <20190913192551.EAB39149B8B9@mailman.qth.net> <3378fdc1-c60d-5b3f-9616-e30b3a5546c0@cis-broadband.com> <77dc272f-0f4d-c4c9-da2b-b1834ae74970@bates.edu> Message-ID: David, Put up a Rhombic favoring the direction of your most wanted DX.

They were usually designed as a compromise between gain and typically one octave of bandwidth (e.g. 14-28 MHz). To compound the design compromises, the r hombic termination resistor throws away nearly 3 dB of whatever gain it might achieve. Because of this, high gain transmitting rhombics have very narrow beamwidth, typically 20-30 degrees. A high gain rhombic designed for 14-28 MHz -- competitive with a pair of stacked large triband Yagis -- might be 300 feet wide, 700 feet long and supported by four 100 foot towers. In order to achieve this gain, the rhombic beamwidth would be only about 25 degrees, requiring at least a dozen huge reversable rhombics to cover most of the compass. I visited many rhombic antenna farms many years ago (as far as I know they've now all been dismantled). They were typically at least one square mile sites with fifty to a hundred towers with heights of 50 to more than 200 feet. Dismantled VOA Site C in Greenville, NC is a good example, a 1.5 square mile site with pairs of massive rhombics -- the biggest I've ever seen -- for diversity reception. To the extent these facilities are still operating (the vast majority are not), the rhombics were replaced by rotatable log periodic antennas, perhaps with higher power transmitters to make up for the slightly reduced gain. That approach replaces a one square miles ( in some cases much larger) with a few acres or perhaps 100 acres for very large site. This is a good reference: www.w8ji.com/rhombic_antennas.htm 73 Frank W3LPL ----- Original Message ----- From: "Mike Markowski" To: elecraft at mailman.qth.net Sent: Friday, September 13, 2019 10:24:32 PM Subject: Re: [Elecraft] Rhombic antenna "gain" Can you expand on this, Ken, or if easier, a reference?

Rhombics for the point-2-point services, horizontal V-beams for the maritime service. VOA was partial to Sterba and other "curtain" designs.? Similar to rhombics in the gain and main lobe elevation departments, they exhibit wider beam widths which was good for broadcast to specific areas instead of specific cities.? VOA had a large station in Dixon CA with multiple curtains which is gone now.? The one in Delano CA was still there [inactive] last time we drove down CA99 to Bakersfield 5 or so years ago.? They do require two or more very tall towers however. There's a trade-off equation.? Rhombics are quite simple and do not require massive towers.? They DO require a lot of land which must be factored into the total antenna cost.? That land has to be kept clear of major vegetation too.? Curtains take less land but are substantially more complex and more difficult to erect, inspect, and maintain.? It always comes down to money.

W6AM had separate Collins KW-1 transmitters permanently tuned for each band, all the feedlines were open wire, and he basically talked to anyone he wanted to.?

It was mainly used for the code practice and bulletin transmissions.? When the new 90-foot tower with stacked monoband Yagis was installed we ran some A/B antenna tests on the air and asked people to send in signal reports. We found that the rhombic was equal or better than the stacked monobanders right on the boresight of the antenna but it had a narrower radiation pattern.? The Yagis covered the west coast better overall. On the other hand, the rhombic was not as high (mounted on telephone poles) and it could be used on other bands, although with lower gain.

When our senior EE class toured Crosley's Mason, OH VOA site in 1964, the engineers were quite proud of their modification to the design that fed the termination power back into the feedpoint. All that remains of that spectacular station is the transmitter building. When we toured it, there were >25 rhombics and two Sterba Curtains. 10-15 years ago, my son worked as the manager for a restaurant/bar on the land where the antenna farm used to be. Several years ago, I drove by the VOA station at Delano, CA, about 45 miles S of Visalia. At least some of the antenna farm was still there, but inquiry told me that the transmitters were "somewhere in South America." At the time, I had hopes of arranging a tour for Visalia DX Convention attendees. There are still some shore stations along the Pacific coast with rhombics. The KPH TX and RX stations are 30-40 miles apart. There's another RX station along Rte 1 S of Half Moon Bay, with an associated TX station around Palo Alto. 73, Jim K9YC From rich at wc3t.us Fri Sep 13 21:02:12 2019 From: rich at wc3t.us (rich hurd WC3T) Date: Fri, 13 Sep 2019 21:02:12 -0400 Subject: [Elecraft] AXE1 In-Reply-To: References: Message-ID: I got my shipping notification today.

There was a small group of hams who either tried, or succeeded, in getting permission to put one of the remaining Delano Sterba's on 160 [and maybe 80].? I'm not sure if they were successful, I do know that the antenna farm you can see from the highway is significantly smaller than I remember from the late 50's. I think the Half Moon Bay stn was KFS.? It's brother site was in the mud flats off of the Palo Alto shoreline in the Bay, all gone now.? At least one of the KFS transmitters is now operating at KPH.

The whole show with rhombics is beamwidth and elevation angle, not really gain, which has been pointed out in much of the literature.? A "perfect" rhombic will have an extremely narrow beamwidth in the 10 to 15 deg range at HF [and if large enough, at MF as well].? Asymmetry will distort that characteristic, and raise the amplitude of side lobes.? Effective rhombics for ham usage will require an "array' of them with different headings.? Lots of land, lots of property taxes. Stacked, rotatable yagi's might be a better choice if your bank account is sufficient.? Trees growing inside a rhombic will slowly degrade its performance, yet another cost.? Of course, you might be able to sell the lumber.

Last weekend, after having been off the air for just over three months, I went to the shack to operate in the Nebraska QSO Party -- needing only NE on 10 to finish the CW 5BWAS. Dead quiet on 10 meters. After an hour of CQ NEQP every 20 seconds, a familiar old-tyme burning smell filled the room. By sniffing everything I found the culprit. Somehow in my absence (or in the absence of my working memory) the KPA had been switched to ANT2, which is my dummy load. It's rated at 1500 watts but it has a time limit. I guess I exceeded it. But no matter. I opened a window, aired out the room, took the fried dummy load out to the patio, switched the amp to ANT1 (a real antenna), and the sound of the band didn't change. At all. Nada. All day. What fun.

Delano, Dixon and further east Bethany were not VOA sites. They were originally private broadcaster?s sites. I can?t remember which was what but Bethany and Delano were CBS and NBC. Bethany was Crosley. Eventually VOA took these sites over as commercial broadcasters found little value in shortwave. Greenville was the only true VOA site on US soil. The engineers who kept these sites going were heros as many of those transmitters became antiques and in some cases had to fabricate parts. That is the unfortunate legacy of US shortwave broadcast. b Sent from my iPad >> On Sep 13, 2019, at 8:48 PM, Jim Brown wrote: >> >> ?On 9/13/2019 4:18 PM, donovanf at starpower.net wrote: >> To compound the design compromises, the r hombic termination >> resistor throws away nearly 3 dB of whatever gain it might achieve. > > When our senior EE class toured Crosley's Mason, OH VOA site in 1964, the engineers were quite proud of their modification to the design that fed the termination power back into the feedpoint.

Much better performance than I expected! Glad to hear you received the AXE1 and gave it a shake-down. Operation with any very short antenna is a challenge, of course, but sometimes it's the quickest way to get on the air. Anyone else try their AXE1 extender yet? 73, Wayne N6KR __._,_.___ Posted by: Wayne Burdick Reply via web post ? Reply to sender ? Reply to group ? Start a New Topic ?

I'm not sure if they were successful, As I remember it, it was the Sacramento Ham Club that got permission to use the antenna at VOA Dixon for a Field Day shortly after the VOA decommissioned the site. After they hooked everything up, they could not hear anything with it because of the high gain antenna picking up the signals from NPG - the Navy's transmitting site - two miles down the street. Someone forgot that there's a reason that receiving sites are located far, far away from such high-power transmitting sites. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From k2asp at kanafi.org Sat Sep 14 00:27:48 2019 From: k2asp at kanafi.org (Phil Kane) Date: Fri, 13 Sep 2019 21:27:48 -0700 Subject: [Elecraft] Rhombic antenna "gain" In-Reply-To: <1f6832b8-8b6b-83d6-88e2-009295c5f790@foothill.net> References: <1645226686.7824688.1568416683578.JavaMail.root@starpower.net> <5eceaad0-5ef4-b7fb-e933-48288eb1c17c@audiosystemsgroup.com> <1f6832b8-8b6b-83d6-88e2-009295c5f790@foothill.net> Message-ID: <8c152f9b-19b6-4cc1-ca79-277d038d0d99@kanafi.org> On 9/13/2019 6:56 PM, Fred Jensen wrote: > I think the Half Moon Bay stn was KFS.?

Ah yes, the PW-15, built for Press Wireless in the 1940s for continuous RTTY press transmissions at 15 KW. It's now running at 5 KW in CW mode and should last as long as we can get tubes for it. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From k2asp at kanafi.org Sat Sep 14 00:32:13 2019 From: k2asp at kanafi.org (Phil Kane) Date: Fri, 13 Sep 2019 21:32:13 -0700 Subject: [Elecraft] Rhombic antenna "gain" In-Reply-To: <496505486.8081255.1568430953400.JavaMail.root@starpower.net> References: <496505486.8081255.1568430953400.JavaMail.root@starpower.net> Message-ID: On 9/13/2019 8:15 PM, donovanf at starpower.net wrote: > Its nearly impossible to hide those old Wullenweber arrays, even if they've > been dismantled for nearly fifty years The FCC's have all been dismantled. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From huntinhmb at coastside.net Sat Sep 14 00:54:30 2019 From: huntinhmb at coastside.net (Brian Hunt) Date: Fri, 13 Sep 2019 21:54:30 -0700 Subject: [Elecraft] Rhombic antenna "gain" In-Reply-To: References: <1645226686.7824688.1568416683578.JavaMail.root@starpower.net> <5eceaad0-5ef4-b7fb-e933-48288eb1c17c@audiosystemsgroup.com> Message-ID: <7F831A92-8B25-409B-8A32-F6E8248C50FB@coastside.net> Not true.

In 1984 I helped install a 250w commercial VHF link from top of Mt. Balleyhoo (above Dutch Harbor in the Aleutians) and there was the remains of many 90 foot wooden poles arrayed up in a valley on the side of the mountain that was used by the military in WWII. I would guess they held rhombic arrays as the poles were in lines with total length probably 1000-foot. Dutch Harbor was attacked by Japan in WWII but did not fall to the Japanese like Attu and Kiska Islands did. The campaigns often referred to as the "Forgotten War". Only US territory occupied by enemy forces since the war of 1812. There were abandoned concrete gun emplacements on the cliffs on top of the mountain - interesting to explore and look out of thinking how it was in 1942. 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From ha4zd at t-online.hu Sat Sep 14 02:54:06 2019 From: ha4zd at t-online.hu (=?UTF-8?B?U3phYsOzIElzdHbDoW4=?=) Date: Sat, 14 Sep 2019 08:54:06 +0200 Subject: [Elecraft] Low activity In-Reply-To: <17708F2E-AC91-4217-97E8-C005235F1507@gmail.com> References: <033b90f2-5d7a-73ef-e41f-bc8f5f1dddef@t-online.hu> <17708F2E-AC91-4217-97E8-C005235F1507@gmail.com> Message-ID: <4d0307fb-f6ba-6b02-770d-3292b5eb0e28@t-online.hu> Thank you , even my mail have not got through.

Then you can reverse it with a flip of the switch. Although transmit gain is the same as bidirectional, you can cut the noise by 3 dB.

If unterminated, they are bi-directional with half the power in each lobe. If terminated, the resistor absorbs half the power in the reverse lobe. Either way, half your power goes the "wrong" way, either behind your desired direction or heats a big resistor. They have a very low radiation angle and a fairly narrow beamwidth which is why they're flame throwers and very common in military and commercial stations, particularly in the days of point-to-point radio circuits. V-beams, sometimes called Half-Rhombics are sort of likewise only broader azimuth patterns more suitable for maritime ship-shore telegraphy circuits.

But I do have a 2 acre "semi-rural" lot, and approx. 400 x 150 feet clear space behind the house. We have an HOA with antenna restrictions, but I managed to get elected to the board and was subsequently able to convince my colleagues to change the rules just a bit. After establishing my coverage goals and analyzing different options for best use of that space (including available supports) and my resources, I decided on an Extended Double Zepp. It's oriented to give me maximum gain at 3.5 MHz in a North-South direction with NVIS properties (desired), and maximum gain in an East-West direction on 40 meters. On 30 meters, and to a lesser degree on 20 meters, it produces NE, SE, SW and NW lobes. It tunes to a very useable match on all bands, 160 thru 6 meters. I feed it with 600 ohm True Ladder Line from a hybrid (4:1 voltage/1:1 current) balun in the attic requiring only about 20 feet of coax to the KPA/KAT500 in the shack. In a box outside I have a balanced line lightning arrestor, and also a heavy duty knife switch for positive antenna grounding (I am admittedly paranoid about lightning ...). It theoretically produces 4.7 dbi gain on the major lobes, and serves my purposes very well on all bands. Prior to the HOA changes, I was limited to a G5RV Jr. in the attic. It worked fairly well, but nothing like this. I still use it as a backup during thunderstorms when the EDZ is disconnected.

Then you can reverse it with a flip of the switch. Although transmit gain is the same as bidirectional, you can cut the noise by 3 dB.

If unterminated, they are bi-directional with half the power in each lobe. If terminated, the resistor absorbs half the power in the reverse lobe. Either way, half your power goes the "wrong" way, either behind your desired direction or heats a big resistor. They have a very low radiation angle and a fairly narrow beamwidth which is why they're flame throwers and very common in military and commercial stations, particularly in the days of point-to-point radio circuits. V-beams, sometimes called Half-Rhombics are sort of likewise only broader azimuth patterns more suitable for maritime ship-shore telegraphy circuits.

Their architectures are quite different and have little in common other than their circular shape. The FRD-13 relies on less effective (but much less expensive) analog RF phasing to develop its front-to-back ratio while the FRD-10 uses a massive (and extremely expensive) reflecting screen. Immediately after World War II, the Soviet Union built and deployed many dozens of Krug DF arrays, direct copies of the German Wullenweber DF array. Some of them are still in use and look almost exactly like the World War II Wullenweber arrays. www.thelivingmoon.com/45jack_files/04images/Krug/Odessa_I_PC030200_8965681.jpg 73 Frank W3LPL ----- Original Message ----- From: "Todd KH2TJ" To: elecraft at mailman.qth.net Sent: Saturday, September 14, 2019 7:25:39 AM Subject: Re: [Elecraft] Rhombic antenna "gain" Correct.

You can't rotate it but you will be heard very well in the direction of the wires. Theoretical doesn't come close to actual. There is no such thing as free space for us mortals.

Elecraft support suggested to check SW ADC readings on pushing the particular PBs. To check the reading, you go to CONFIG menu and select SW TEST to ON. You need to set TECH MD to ON for the test. Please use SW TEST to test the performance of the buttons in question . Pressing M>V with SW TEST on reads approximately 7 164 and flickering 7 165. Pressing V>M with SW TEST on reads approximately 7 191 and flickering 7 192. While in SW TEST, also check the performance of all four rotating knobs which contain push buttons and are near green LEDs. The rotation of knobs do not report values in SW TEST, but depressing the buttons does. Values are approximately [0-3] 040. Note if any on these switches are non functional, and if so, 'flick' the surface of the knob of the button to temporarily nudge it into functionality. Then, retest M>V. Occasionally, the effect of one knob button effects other buttons. In my case, the problem was caused by worn switch contacts behind the PBs. So, replacing the switch units on the K3 front panel PCB fixed the problem. 73 de JH3SIF, Keith > 2019/09/15 1:37?George Johnson W1ZT ????: > > Need some direction where to look. > > My K3 seems to have lost control of the front panel buttons.

His pattern dropped off drastically as the moon exited his window. When I built my humongous 144 MHz array in 1979/80, I figured that my window with VK5MC would be a bit wider with the added gain from the 24 yagi array.? It hardly varied at all! He just got louder when I could hear him. I might have picked up one minute.? Great fun thinking about those times! Thanks. To make this Elecraft related, I wish I had a K3 for my EME receiver instead of the Collins 75A4 that I was using back then. The APF would be fantastic on CW EME. It would have saved me a lot of time modifying the A4 to make it better!!? I replaced the 6BA7 mixers with 6DJ8s. I took out an IF can and dropped in an R-390A 2.0 kHz mechanical filter. I had to add a 2N4416 FET to account for the added loss in the filter. The last big mod was to add another Collins 300 Hz crystal filter in the CW fillter position. I jury rigged it underneath the chassis on a bracket. I still have the 75A4 and did a cap replacement last winter. It had not been fired up since about 1992. It needed work. After it was all working fine again, I checked MDS? (-138 dBm) and close in dynamic range at 2 kHz. I saw 92 dB which is not too shabby and in a different league than a stock A4. Still it is a good 10 dB below the K3. Dave K1WHS On 9/14/2019 12:09 PM, Wes wrote: > I completed my 2-meter WAC by working VK5MC on December 3, 1982.

I should have gone into more detail. We did sustain a direct (yes, direct ...) lightning strike on our house in March, 2012. A freak storm after a week of 80F+ temps in Chicago. Lightning struck an attic roof fan, followed the wiring to the basement, and did nearly $100k damage to the house. I had NO antennas of any type up at that time. But I did subsequently have lightning protection professionally installed, consisting of a number of lightning rods on the roof all connected inside along the ridge line with 00 gauge stranded copper, running to 10 foot ground rods at both ends of the house. This wire runs well above the G5RV in the attic ... far enough to protect it and also far enough to 'not' act as a Faraday Cage. Would another direct strike still cause issues? Possibly, but I feel much more secure with that antenna in a storm than the outside EDZ. 73, Lyn, W?LEN -----Original Message----- From: Don Wilhelm [mailto:donwilh at embarqmail.com] Sent: Saturday, September 14, 2019 8:51 AM To: Lyn at LNAINC.com; 'Elecraft Reflector' Subject: Re: [Elecraft] Rhombic antenna "gain" Lyn, Hopefully you do not trust that an antenna in the attic will not be susceptible to lightning.

The forward power at that point is about 400w. The antenna is a double bazooka that shows an SWR of about 1.2 on a RigExpert AA-230Pro antenna analyzer. A Telepost LP-100A digital wattmeter shows SWR 1.3 with Z=52, R=49, Ph=17, and X=15. The KP1500 tunes to an SWR of what it labels 1.1 on that frequency. The latest firmware, version 2.27 is installed. This problem does not occur with double bazooka antennas on 80m or 30m, or with Yagis from 20m to 6m. It seems to me that there is a brief surge in reflected power at the very onset of the transmission that triggers the response, but that the reflected power quickly decreases to normal levels of just a few watts. Any ideas for dealing with this problem would be much appreciated. 73, Steve K2SN From rocketnj at gmail.com Sun Sep 15 20:04:22 2019 From: rocketnj at gmail.com (rocketnj at gmail.com) Date: Sun, 15 Sep 2019 20:04:22 -0400 Subject: [Elecraft] Reflected power In-Reply-To: <000f01d56c21$5c837fa0$158a7ee0$@optonline.net> References: <000f01d56c21$5c837fa0$158a7ee0$@optonline.net> Message-ID: <00ee01d56c22$4b9c25b0$e2d47110$@gmail.com> Check your connections.

Dave's comments are the first place to look. Try also changing jumper cables. What also could be happening is RF flowing back on feedline in a common mode. This RF gets measured as return energy and now, since the power is higher, the return currents are higher and hence the high SWR reading. You won't see this with your RigExpert. Does the same problem happen into a dummy load? If Yes, it is an amp issue. If no, it is a antenna/feedline issue. I would try some RF chokes (Mix 43) on both ends of the feedline (antenna and amp end). I chased strange RF issues for decades until I read this document by the YCCC/W1HIS. http://www.yccc.org/Articles/W1HIS/CommonModeChokesW1HIS2006Apr06.pdf. After that I bought about 100 Mix 43 chokes and added them everywhere. Not only does it help with unique RFI TX issues, it also helps with the ability to hear. The quieter you are, the more you can copy. Let us know how you make out. Mike va3mw On Sun, Sep 15, 2019 at 8:05 PM wrote: > Check your connections. Loose or poor PL-259s.

It is a fallacy that antennas like this do not need a serious common mode choke, and it must be at the feedpoint (that is, up in the air). Indeed, common mode current may be putting RF in the shack.

He said "the return currents are higher." SWR describes what is going on INSIDE the transmission line -- the differential current. Common mode current is OUTSIDE the coax (or, in the case of 2-wire line, the difference between the current on the two conductors. Now, common mode current CAN de-tune the antenna to the extent that the feedline becomes part of the antenna, but the resulting SWR would be correctly measured by the LP100A. It might NOT be correctly measured by the RigExpert, because it breaks up the common mode circuit. Further -- standing waves on the feedline exist inside the feedline (or between the conductors), and voltage and when there is SWR, current and voltage vary along the line in a manner determined by the VF of the feedline. But in the common mode circuit, the feedline acts as a single wire with a VF near 0.98, depending on diameter and insulation, and common mode current and voltage vary along the line just as they would on any other antenna. 73, Jim K9YC On 9/15/2019 9:53 PM, Vic Rosenthal wrote: > He didn?t say common mode current WAS reflected power.

Make sure none of the audio controls (including the mislabeled "POWER" slider in the application software) are not set near the upper or lower extremes. You have at least 3 level controls to consider - the POWER control in the software, the soundcard SPKR or LINE OUT, and the LINE IN level on the K3. As others have mentioned, some soundcards have humps and valleys in their output response, so the output may vary with the audio frequency. You can decide whether to live with that or get a soundcard with a flatter response curve. 73, Don W3FPR On 9/15/2019 11:23 PM, Jim Miller wrote: > K3 original - ALC erratic > > Noticeable on digital mode(s?)

With a dummy antenna (Cantenna) on 7MHz, and a 1.1:1 match, using 10w drive the KPA-1500 puts out 605w at first, then settles down two seconds later to 384w with 8w reflected power. With 25w drive, the initial output is 1431w, settling down to 1105w after two seconds, with 20w reflected power. So, the fault seems to be in the antenna, not in the amplifier. The same initial power surge occurs on 14MHz using the dummy antenna. I don't know if it originates in the transceiver or the amplifier, but it doesn't have much effect on reflected power except with the defective antenna. Answering some of the questions that were posed, the double bazooka in this case is the high power version from Radiowavz, two years old. A common mode choke from DX Engineering sits between the end of the feed coax and the antenna. Several Mix 31 snap-on chokes from Palomar are on various short coax jumpers in the shack, and the ground system is very good. The double bazookas I use on 80m and 30m work well and are from iacantennas.com. I am ordering a 40m version from them to replace the one that seems to be faulty.

Elecraft support suggested to check SW ADC readings on pushing the particular PBs. To check the reading, you go to CONFIG menu and select SW TEST to ON. You need to set TECH MD to ON for the test. Please use SW TEST to test the performance of the buttons in question . Pressing M>V with SW TEST on reads approximately 7 164 and flickering 7 165. Pressing V>M with SW TEST on reads approximately 7 191 and flickering 7 192. While in SW TEST, also check the performance of all four rotating knobs which contain push buttons and are near green LEDs. The rotation of knobs do not report values in SW TEST, but depressing the buttons does. Values are approximately [0-3] 040. Note if any on these switches are non functional, and if so, 'flick' the surface of the knob of the button to temporarily nudge it into functionality. Then, retest M>V. Occasionally, the effect of one knob button effects other buttons. In my case, the problem was caused by worn switch contacts behind the PBs. So, replacing the switch units on the K3 front panel PCB fixed the problem. 73 de JH3SIF, Keith > 2019/09/15 1:37?George Johnson W1ZT ????: > > Need some direction where to look. > > My K3 seems to have lost control of the front panel buttons.

Checked in today on my KX2 with both the Noontime Net 7283.5 and the Jefferson Noon Net 7204, while walking along the ocean bluff trail near my home at The Sea Ranch, dragging the counterpoise in the dirt behind me. Stan AA6SC was quite amused when I said that I was pedestrian mobile. I suspect that the location near the ocean is a factor in the performance, but I will try it elsewhere as well when I have the opportunity. The noise level was very low today; not even registering on the S meter. Reception was very good, with most signals S7 to S8. I am a bit concerned that the long lever arm of the antenna combination may be introducing some strain on the KX2 BNC connector, so I try very hard to keep the rig vertical and not allow the whip to move around too much.

Bob: I tried different microphones (MH4, SHURE 444, HEIL HC-5) with mic gain and compressor settings down to inacceptable and with all three of them I get the same effect. That is with PTT pressed and the microphone level other than ?0? and the noise gate OFF on an SDR receiver I see a tx noise floor block according to the filter bandwidth. However at approx. 2,5 kHz I see a ?needle? that reaches 17 dB above the ambient noise floor. If I turn on the noise gate the tx noise floor is suppressed and so is the needle. Speaking into the microphone in order to open the noise gate the needle is masked by the speech energy however in breaks and before the gate closes again the level drops to the ambient noise level and the needle becomes visible again. It is always there but just covered by the speech energy. That is what makes the modulation ringing on top and at the end of each word. Reducing the compression has no effect other than lowering the overall signal ? the tone is still there. I even tried to lower the 2,4 kHz level in the TX EQ but it has no effect as the noise is right on 2,5 kHz. The only thing that would help I guess is a software notch filter in the DSP that eliminates this spur or artefact or best avoid it at all. Disconnecting the microphone doesn?t change anything either. As soon as the Mic Gain level is other than ?0? the tone is there microphone connected or not. So it seems it is an artefact that?s created in the radio but absolutely no noise pickup from the microphone. I tried 4 different radios ? legacy and SDR and none of them shows a single tone on top of the tx noise floor but a smooth and more or less straight top of the tx noise caused by ambient noise. If no SDR is on hand a local remote SDR will do. 73s Roger, DL5RBW From: Bob McGraw K4TAX [mailto:rmcgraw at blomand.net] Sent: Monday, September 16, 2019 8:05 PM To: Roger Subject: Re: [Elecraft] K3S issues Roger: Radio wise, I set my K3S just as I normally use it for SSB QSO's. The mike is selected at FP.H and the mike is a Shure SM-58 dynamic mike. The MIC gain value is 35 and the CMP value is 15. When monitoring the radio using another receiver, I do hear some noise in the audio spectrum. This noise is displayed on the SDR receiver using HDSDR as being in the 1500 Hz to 2500 Hz range with a peak value about 2200 Hz. Setting the MIC gain value to 0, I find the noise goes away. Nothing observed or heard. The setting the MIC gain back to 35 but disconnecting the mike from the front panel and then keying the radio as before, there is no noise. My conclusion is that the mike is just picking up ambient sound in the room. The use of the Speech Processor does bring the noise level up as opposed to when the CMP is set to a value of 0. I normally run the CMP at a value of 15. My conclusion is there is nothing I can see or hear coming out of the radio, unless it it going into the radio via the connected microphone. The measurements show the level to be some -70 dB below 100 watts PEP. With 100 watts PEP being 50 dBm re 50 ohms, then - 70 dB below that is 0.00001 watts. Now if your friend is seeing your 10M signal at -43 dBm or S-9 +30 dB, then a signal that is -70 dB down is still and S-2 signal of -115 dBm. In a quiet band condition, that could easily be heard. My measurement were with the noise gate set to OFF. 73 Bob, K4TAX On 9/16/2019 12:30 PM, Roger wrote: Hi Bob, it is strange with that noise as nobody ever told me but gave me unsolicited reports on the good audio which I believe is true when it comes to frequency response. The first time I encountered this problem is when F5VNE and I4LEC told me about it on 40 m SSB 4 weeks ago. We checked and rechecked and finally it appeared that it was gone and the TL-922 ?s fan was the noise source. Signals went down by that time and so I guess we came to a wrong conclusion. Then a week ago a local friend (1 mile away) immediately told me about this noise. As there was no QSB and the signals well over S9 I tried all the things I described including battery power to make sure the switching mode powersupply is not causing any trouble. No way I could get rid of the noise except cranking down the mic gain to the level where the audio became drastically weaker and the noise gate took care of it. As soon as the noise gate opened when talking the ?ringing? could be heard in the background. However it is best heard with the noise gate disabled and just the PTT pushed. I wonder what you find out. 73s Roger, DL5RBW From: Bob McGraw K4TAX [mailto:rmcgraw at blomand.net] Sent: Monday, September 16, 2019 3:16 PM To: Roger Subject: Re: [Elecraft] K3S issues Roger: Thanks for the detailed response. As my friend says "there's a lot of buckshot in that message". On the other side, as is often said, "if it is working, don't try to fix it". I agree with that. Perhaps time permitting today, I'll make an effort to look closer for the noise you describe as a distant cell phone ringing. I've not had any reports of noise on my signal in this regard. Some of the fellows I chat with are serious audio critics and I'm sure if something was amiss I'd be told about it. As the weather is supposed to be very hot today with temps in the mid to upper 90's F, likely this will be and "indoor under the air conditioning" day for me. Time to play radio. That is after I get the things done which my wife dictates. 73 Bob, K4TAX On 9/16/2019 6:40 AM, Roger wrote: Hi Bob, I was briefly thinking about a connector problem as especially the older versions of the K3 (K3S?) had issues with the tin plated pins. Starting to disassemble the radio and puliing/pushing boards is something I had lower down on the priority list especially as it gives the false impression of a successful ?repair attempt? as long as the fluctuation is on an irregular basis and doesn?t show up after pulling the boards. So I wanted to check out if someone else had a similar issue. As it didn?t show up anymore I leave it with that until it becomes a bit more steady. Concerning the audiochecks I only use a 2nd station receiver for a basic first check if something is really off track or at least acceptable to start with because of exactly the anatomic reasons you lined out. The same is true if listening thru headphones on a remote SDR ? HOWEVER the latency of the signal until it is processed in the SDR takes some time and there is yet another delay in getting the signal thru the internet to your computer and finally to the headphones. With the local SDR (5 miles away) the signal on an empty 10 m band is strong enough to even hear the details yet there is a gap of 2 to 3 and sometimes 5 seconds before the audio arrives at my headphones/loudspeakers. So there is plenty of time to talk and transmit for a couple of seconds then stop and listen to your signal like any other listener would. The latency on some remote SDRs can in fact be controlled to extend the latency. No impair due to ?anatomic feedback? whatsoever. Recording and playing it back can be done with this method as well as the SDRs offer a record and playback function. So the only difference is that you record your audio thru an artificial communication path with absorbers or attenuators while the other way is via a real path. Once you use a local SDR, the signal level is strong enough and the noise level is low (like the closed 10 m band) it is an absolutely valid method proved by many others with a good audio. ALC indication on my setup is up to 7 bars which is just fine. The compressor level has no impact on when the noise gate starts to open. If it is easy to accomplish (which I don?t know) a selectable level up to the point where even speech close to the microphone is almost cut off would be fine. Everyone could pick the level to suit his individual situation from 0 to max. In OPENHPSDR you can almost choke off your speech by selecting the maximum noise gate level. But you can go down 0 and everywhere in between. The noise situation here is as it is. It is not a particularly quiet environment with the amplifier running 20 inches away from the radio nor is it a particular noisy environment ? from what I have seen the last 40+ years of ham radio it is below average so nothing to worry about. In fact with OPENHSDR and the possibility to select a higher Noise Gate level the noise gate doesn?t open with the background noise yet is still sensitive enough to open reliably while speaking into the microphone. And there is still plenty of headroom to lift the level without being not sensitive enough for speech. By the way testing around with the noise gate level somebody told me that a high frequent hiss is coming along with the signal especially if it goes beyond approx. ? 43 dBm. Noise Gate on or off didn?t make any difference. Switching to other radios the noise was gone. Swapping powersupplies and even going for an emergency battery the noise was always present although the ambient was completely quiet (amplifier off, computer off etc.). I listened to the remote SDR and in fact it is there. Yesterday listening to a HB9 station on 80 m he had exactly the same noise coming along and after having a few words with him he confirmed that he is using a K3S. It sounded like a distant cellphone ringing ? one of those typical old analog phones where the rings merge to an almost constant tone. With the SDR I may be able to determine the frequency of that tone. Anyway it sounds like I don?t like the radio which is not the case. It?s fun to experience the phenomenal receiver and the possibilities it offers especially with a second receiver and some other useful accessories. But if something odd shows up it is always worthwhile to stop and investigate????????????? 73 Roger, DL5RBW From: Bob McGraw K4TAX [mailto:rmcgraw at blomand.net] Sent: Saturday, September 14, 2019 1:54 AM To: Roger Subject: Re: [Elecraft] K3S issues Roger: I'd say the issue with the current indication is a front panel issue. There are several connections that affect the display. Might do well to check those, even pulling the front panel and cleaning the connectors. I don't agree using a remote SDR for the purpose of checking ones signal or audio. It is much better to use a local receiver with termination on the antenna input. Record the output so one can listen to the signal. Record a bit of transmission, and play it back for evaluation. Due to sound conduction through the human head, it is not realistic to use headphones and talk at the same time. The sounds of speech as conducted through the bones in the head to the inner ear, while one is talking, is not realistic of what the transmitter is producing nor what the receiver is hearing. Recording and playback is the much preferred method. You are correct in that the monitor function only samples analog audio. It does not represent the RF waveform. If you find that TX Gate value of 25 is not adequate, that indicates you have a lot of mike gain which would be considered excessive and thus a large amount of noise ambient or otherwise in the room. I suggest you carefully review your mike-to-mouth technique and your MIC gain settings. If you are running the MIC gain at a value of 25 or less, I recommend you check to see if High Gain is activated. Ideally the MIC gain should run in the 35 to 45 numerical range. This will be somewhat dependent on mike technique and the type of mike being used. Values typical of my satisfactory operation for TX Gate is 06 to 07. The MIC SEL is set to FP.H with a MIC gain of 35 using a Shure SM-58 dynamic mike. Also the TX EQ is set as follows: 50 Hz -16dB, 100 Hz -16dB, 200 Hz - 9dB, 400 Hz -3dB, 800 Hz -0dB, 1.6 kHz -0dB, 2.4 kHz +3dB, 3.2 kHz +6dB. If you haven't attenuated the low end significantly, as shown above, this could be the source for some very low frequency energy which consumes lots of power in the spectrum but provides little communications intelligibility. This could also be the source for the TX Gate which appears as not having adequate range. Just trying to be of assistance with an audio issue. 73 Bob, K4TAX On 9/13/2019 4:55 PM, Roger wrote: -----Original Message----- From: Bob McGraw K4TAX [mailto:rmcgraw at blomand.net] Sent: Friday, September 13, 2019 11:04 PM To: Roger Subject: Re: [Elecraft] K3S issues Roger: The current value of 1.4 A is about correct for receive mode. Then in transmit mode, SSB no signal, the current is about 2.8 A. If the last digit of the current is moving around, I see the same thing. It is minor and just a toggle between bits or resolution. Maybe it was a bit unclear - the radio sat in RX mode and the display was jumping from 1,4 A to 2,7 A in RX mode without doing anything. It was not the actual current consumption but only the display that was erratic. Idle current on TX is higher in my case but that?s another story. I think first one should set the MIC Gain and CMP values for normal expected operation with the TX Gate at OFF. Then set the TX Gate to ON and start increasing the value from 00, while listening to the MON via headphones. The correct point is the value +1 where the noise is muted. In my station a Noise Gate value of 06 to 07 is ideal. If you change mikes, you will have to reset the Noise Gate value and likely the Mic Gain values as well. This is due to different mikes having different output levels and different pick-up patterns. Be sure to start with the CMP off or 0 and then adjust the MIC gain such with normal voice and the mike of your choice you will observe no more than 5 to 7 bars on the ALC scale. If you change to a different mike, you will likely need to adjust the MIC gain value for that mike. Once this is done, set the CMP value to indicate about 3 to 5 bars on the CMP scale. This is the correct method for setting MIC Gain, and CMP value, based on the ALC indication. I don't consider listening on another receiver to be a valid means of adjusting the MIC Gain or CMP value. All of this is covered on page 30 of the manual. I don?t know whether you ever used a remote SDR but that?s the best way you can check your signal in many aspects. Listening to a second receiver next to the transmitter with the headphones on is a means to get a rough estimate at best. However using an SDR which is "decoupled" also in terms of time (latency is the keyword here) is an ideal means. Don?t forget to set the bandwidth wide and flat! The monitor function can be used for setting the noise gate but other than that it only gives you the unprocessed signal. Most of the radios with monitor function will NOT sample or tap the actual signal on the antenna port. I don't find any issues where the system does not perform as designed and expected. Well an erratic display can hardly be considered a design goal but I believe it is more likely a part problem. The noise gate however could easily offer a bit more headroom or a higher ?release? level. If you get away with a lower level no problem if it is adjustable down to 0. If one needs a higher level because of a higher ambient noise the maximum setting as it is right now couldn?t be enough. 73 Bob, K4TAX 73/Roger On 9/13/2019 3:37 PM, Roger wrote: > Good evening, > > 1. > when I turned on the K3S tonight I noticed that the current display > was jumping between 1,4 and 2,7 Amperes on idle.

The Elecraft website still lists the Remote Rig units (RRC-1258MKII) for use with the K3/0-mini with pricing but there aren?t images showing what the products look like. I was also able to add the Remote Rig 1258MKII to the website?s ?cart? so presumably that means they are still available. An alternative source is Ham Radio Outlet. The last time I looked, they were selling the entire line of Remote Rig products. However, RRC-1258MKII units purchased through HRO would require the user installing the proper internal jumpers to work with Elecraft whereas the version offered by Elecraft are preconfigured for their products. HRO also offers the RC-1216H that provides a web-based interface to remotely manage the KPA-500 as well as certain rotors such as the Green Heron RT-21. I purchased two RC-1216H devices - one to control my KPA-500 and the second to control my Orion rotor through the Green Heron controller. I just wish they expanded their product?s capability to also manage the KAT500! Hope this helps, Barry Baines, WD4ASW Keller, TX (Currently in Boston, MA) > > Tnx. 73 de Brian/W3BW > -- > > *Brian F.

In TX mode, it can put out a few dBm at the XVTR OUT jack for use with external low-band transverters. Since the K4 also has provisions for an *internal* transverter, we could in theory offer one in for these bands. Power output could be as much as 10 or 15 W. This is all speculative, though, as the plan has been to cover one or two VHF/UHF bands with the internal transverter module. 73, Wayne N6KR > On Sep 19, 2019, at 11:10 AM, Joel Hallas wrote: > > I have been very impressed with the architecture and features of the K4, as > announced.

Unplugging the mic to plug inn the cables from the sound card is an hassle. Not to mention that one have to adjust levels every time. An other option would be some sort of TNC connector.

Tomorrow the 30 meter band gets a try-out. I am impressed, especially since most of my operating is portable.

The K3s has a builtin USB sound card, so leaving it out of the K4 would not meet user expectations of what flagship rig like the K4 should look like. Considering there's a USB sound card built into most modern rigs now, it would look bad when comparing them. I can even hear the whining and moaning now "You are telling me that the IC-7300, which costs less than a quarter of the price of the K4 has a built-in sound card and the K4 does not?" -Eric On Tue, Aug 20, 2019 at 11:48 AM David Gilbert wrote: > > What does the built in sound card buy you?

All has been working fine for the last 4 days now so I am declaring "victory" for the present time. I was advised by Elecraft Support that I may have a "gradually failing encoder" and to make sure I have a backup of the Configuration File for my radio (which I always do). My K3 S/N 7114 is about 7 years old now and on the air almost daily. I am looking for a backup K3 or K3S to support my station in case something like this happens again. I need a quick recovery of operations if I lose the radio. I will have more of a discussion with Elecraft about encoder life and assess various options. Anyone who has gear they plan to replace (upgrade to K4) please contact me directly with interest and information. Thanks again to all for your quick responses to my request for ideas. 73, George W1ZT -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of George Johnson W1ZT Sent: Monday, September 16, 2019 2:54 PM To: 'Keith Onishi'; Elecraft at mailman.qth.net Subject: Re: [Elecraft] K3 Lost Control of Front Panel Buttons Keith and all, Thank you for your quick suggestions. I have heard back from Elecraft Support also and am running these checks. The problem is intermittent and I was able to run the tests Keith described. Elecraft suggested the same tests this morning. Still intermittent but I am also able to control the radio via Win4K3Suite so it got me through several MARS traffic nets on the weekend. Will advise all of any "final" solution but your suggestions are very helpful. I need a "live" spare K3 to back up my station. K3 radio is too important and too good to not be QRV!! 73, George W1ZT -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Keith Onishi Sent: Sunday, September 15, 2019 6:27 AM To: Elecraft at mailman.qth.net Subject: Re: [Elecraft] K3 Lost Control of Front Panel Buttons I have lost control of some particular PBs which have been used most often. Elecraft support suggested to check SW ADC readings on pushing the particular PBs. To check the reading, you go to CONFIG menu and select SW TEST to ON. You need to set TECH MD to ON for the test. Please use SW TEST to test the performance of the buttons in question . Pressing M>V with SW TEST on reads approximately 7 164 and flickering 7 165. Pressing V>M with SW TEST on reads approximately 7 191 and flickering 7 192. While in SW TEST, also check the performance of all four rotating knobs which contain push buttons and are near green LEDs. The rotation of knobs do not report values in SW TEST, but depressing the buttons does. Values are approximately [0-3] 040. Note if any on these switches are non functional, and if so, 'flick' the surface of the knob of the button to temporarily nudge it into functionality. Then, retest M>V. Occasionally, the effect of one knob button effects other buttons. In my case, the problem was caused by worn switch contacts behind the PBs. So, replacing the switch units on the K3 front panel PCB fixed the problem. 73 de JH3SIF, Keith > 2019/09/15 1:37?George Johnson W1ZT ????: > > Need some direction where to look. > > My K3 seems to have lost control of the front panel buttons.

This means that you have to be careful not to have any noise in the shack while transmitting digital. If there is a way on the K3, service was not able to point it out." It would be very surprising to me if K3 and K4 had such a limitation. This situation is handled perfectly in the Kenwood TS-590 by using 2 distinct keying commands. Front panel PTT is equivalent to CAT TX0; and takes modulation from the front panel mic jack. TX1; and the equivalent ACC hardware PTT, take modulation from the USB Audio CODEC or ACC analog audio input leaving the mic muted. Switching between front mic and digital is simply accomplished by asserting the appropriate PTT line or CAT command. The digital mode application asserts TX1; Keying mode cannot be changed while transmitting so first keying command wins until TX stops. 73, Andy, k3wyc From zuceman at yahoo.com Fri Sep 20 13:40:41 2019 From: zuceman at yahoo.com (bruce whitney) Date: Fri, 20 Sep 2019 17:40:41 +0000 (UTC) Subject: [Elecraft] K4 Remote Ops Q?

Then set the K2 secondary menu to PA ON and tap DISPLAY. You should see Fan NOR, Fan LO-HI, then Fan HI with subsequent taps. With FAN NOR and the KPA100 quite cool, both U1 pins 11 and 12 should be at 12 volts. With FAN LO-HI, U1 pin 12 should go to near zero volts and the fan should run at low speed. Pin 11 voltage will drop a bit, but should be higher than 5 volts. With FAN HI, the voltage at pin 11 should drop to near zero and the fan should go to high speed. Now if the fan did not start at the LO speed, put a resistor in parallel with R31 - I would suggest starting with 1k and then going to a lower value if it still does not start. Some fans need a bit more current to start. After all that, put the fan back to NOR and then let the KPA100 and K2 return to room temperature with no power on (about 1/2 hour). Measure your room temperature and convert to degC if your thermometer does not have a C scale. Turn the K2 on and do CAL PA TEMP - set the value at your room temperature in degC. 73, Don W3FPR On 9/20/2019 2:33 PM, Robert G Strickland via Elecraft wrote: > I cannot get the fan in the 100w module to spin at any setting of the > fan control option in PA/SEC/fan.

When the K3 is set for Digital A, it sets USB and uses the Line Input. To switch from LSB to a digital mode, all you need is to change the Mode (the rocker switch). Elecraft radios can be set to remember settings by Mode, so when you switch, you return to your last used settings. I use VOX for all digital modes and voice, which further simplifies things. 73, Jim K9YC On 9/20/2019 1:29 PM, RALPH TURK wrote: > I can not use the digital modes because I need to switch to Upper SB after the last > electron has been sent in the digital mode and the reverse.

In-Reply-To: References: Message-ID: Hi Brian, I designed the Y-BOX to eliminate the tangle of 15-pin Y-cables and custom cables that you would otherwise need if you wanted to connect any or all of the following to the K3 or K3S ACC port: - RemoteRig interface (RRC-1258 MKIIs) - KAT500/KPA500 or KPA1500 - microHAM MK2R+ or micro2R (u2R) - Top Ten Band Decoder, Top Ten Band Aide - Mortty or other FSK RTTY Keying Interface - SteppIR Tuning Relay Interrupt - N8LP Tuning Relay Interrupt - Anything else that wants to use the K3 ACC port Most of the above work using cables supplied by the manufacturer or with standard economical stereo cables. Note that the Elecraft KPAK3AUX amplifier interface cable kit with tuning relay interrupt gender changer ($35.95) is NOT needed to connect an Elecraft KAT500 / KPA500 or KPA1500 to the K3/K3S, as a pair of $10 - $12 cables connected through Y-BOX v2 is electrically equivalent. I have also made other devices work through the Y-BOX using Elecraft interface cables supplied by the manufacturer or by me, including: - Elecraft KRC2 - Array Solutions Bandmaster band decoder - OK2ZI Band Decoder - Low Band Systems (RA6LBS) SO2R Filter Interface - 4O3A Antenna Genius * - 4O3A Power Genius XL * - Yaesu amplifiers * - SunSDR MB1 * * These devices often need a 12 VDC source and pull-up resistors when sharing the Band Data lines, which can be added inside the Y-BOX upon request. In sum, for any amateur radio device that uses a 15-pin D-SUB connector (2-row DA-15 or 3-row DE-15) or a Band Data BCD interface, the Y-BOX can serve as a convenient 4-way splitter and breakout box for that device. My other product, the Serial Box (S-BOX ) and S-BOX-USB can serve as a SERIAL PORT splitter and USB-to-serial interface for other products that need to share a radio's serial port with a PC, such as the SteppIR control box, and SPE and ACOM amplifiers. It also supports computer-generated CW and FSK keying and PTT. The RemoteHams software "Remote Power On" feature for a K3 or K3S is fully supported, plug and play. The S-BOX-USB also works as a convenient USB interface and "docking station" for the Elecraft KX2 and KX3 with support for rig control and computer-generated CW / PTT keying over a single USB cable.

NW6V) Date: Tue, 24 Sep 2019 13:39:04 -0700 Subject: [Elecraft] September 25th is VAIL Day - The First Telegrapher Message-ID: Greetings. Wednesday 25 September 2019 is the 212th birthday of Alfred Vail. While Samuel F. B. "Finley" Morse is correctly credited with conceiving and parenting the telegraph as a communication system - the global wired information network and business - the details of how information was to be passed across that network, using human operators, was largely the work of his partner, Alfred Vail. In other words, Morse invented the "electro-magnetic telegraph," but Vail was "The First Telegrapher." Among other things, Vail invented the straight key, the up/down printing register (which first revealed the signals as "dots and dashes"), discovered "copy-by-ear" (listening to the thunking of his printing register), and authored "American Morse" (to increase efficiency and throughput using his keys and printers). Vail may also have invented the original dot-dash alphabet, which was used for some early demonstrations, and was at worst its co-author. I'm writing a book about all that, hoping to pierce the fog of time and render our understanding more clearly. But one thing was abundantly clear: Morse's telegraph was the first "smart device" - made so by the inclusion of the telegrapher's mind as an integral component of the system - performing "copy by ear." This gave it a critical market advantage early on when line quality was terrible, and mechanical reliability poor. As a matter of the greatest irony, until its inevitability was forced upon him by those economic realities, and the weight of telegraphers almost universally practicing it, Morse was strongly opposed to copy-by-ear because it diminished the importance of "permanent printouts," which were a key distinguishing feature of his original invention and the original patents. You see, Morse never imagined copy-by-ear would happen, or that it was important. Vail lived it. So: I'm commemorating Vail's birthday by using a replica of Vail's straight key for all QSOs on the 25th, and I'll be calling "CQ VVV." There's a picture on my QRZ page. The key works well up into the low 20s, but I'm always happy to QRS. Feel free to join in and send some Vs yourself! Hope to work you on the air! Oh, and I'll be using a K3 and KPA500...:-) 73 Chris NW6V From radiok4ia at gmail.com Tue Sep 24 17:57:18 2019 From: radiok4ia at gmail.com (Buck) Date: Tue, 24 Sep 2019 17:57:18 -0400 Subject: [Elecraft] new revision of KPA500 LPF T_R Switching rework Rev.E guide available In-Reply-To: <1569335232687-0.post@n2.nabble.com> References: <1569335232687-0.post@n2.nabble.com> Message-ID: <8f16aeab-1d67-339a-9ad7-04190aa959c7@Gmail.com> Do we have a first serial number that is "safe?"

(See http://k9yc.com/2018Cookbook.pdf ) Is it matched to the feedline at the frequency (ies) where you're trying to use it? How is the feedline matched to the KPA? Have you used other high power amps with that antenna? Remember that SWR is NOT a descriptor of antenna performance. High power can expose antenna and feedline problems that are not evident at 100W. Are there elements of the antenna that could be breaking down with high power? Look at coax, connectors, how they are soldered, etc. What happens at lower power (500W, for example)? 73, Jim K9YC From jim at audiosystemsgroup.com Fri Sep 27 05:18:55 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Fri, 27 Sep 2019 02:18:55 -0700 Subject: [Elecraft] KPA-1500 failing on 160...AGAIN!

The typical KPA500 misbehavior sounds like it is arcing inside and smells the classic something is burning smell. The SWR LED's are dancing upwards as it arcs. If you have connected the KAT500 tuner then it has the SWR around 1.3:1... and power is lost. ----- 73 - Petr, OK1RP "Apple & Elecraft freak" B:http://ok1rp.blogspot.com MeWe: https://bit.ly/2HGPoDx MeWe: https://bit.ly/2FmwvDt -- Sent from: http://elecraft.365791.n2.nabble.com/ From john at kn5l.net Fri Sep 27 06:02:41 2019 From: john at kn5l.net (John Oppenheimer) Date: Fri, 27 Sep 2019 05:02:41 -0500 Subject: [Elecraft] Unbuilt K1 Found Message-ID: <8ae3ae71-c534-097a-2aff-df17ecfcdee0@kn5l.net> They are out there.

It can still be part of the problem at 1500 watts and if memory serves me well, that is about 275V (RMS) at 50 ohms. Something could be breaking down at that voltage so a good visual inspection would help.

Stimulated thinking and as quoted. 73 Bob, K4TAX "We need more power. I'm giving her all she's got, Captain! She cannae take anymore. I'm sure your Scottish ancestors are rolling in their graves right now, but in our community of radio amateurs we have a tendency to advocate the use of more power. More power fixes all problems and hides all sins. Another way to look at that is to think of the station with more power as an alligator, all mouth, no ears. Before you dismiss this as another advocacy for QRP or low power, let me point out that more power creates more interference, more potential for harm, more electricity consumption, more wear and tear and more cost. Previously I've spoken extensively about QRP communications, making contact with 5 Watt or less, but let's have a look at how much less. I've shared with you that I managed to contact a station on the other side of the planet with only 5 Watts, Perth to Cuba and for me that was proof positive that all this was possible, even feasible. We're doing much better than that. One measurement is to calculate how many kilometers per Watt you achieved. My example of 5 Watt between Perth and Cuba is the equivalent of 3592 km per Watt. The maximum distance to the opposite side of our globe is about 20,000 km and my contact did nearly 18,000 km. If you think that's amazing, I should warn you, my contact was special, for me, but as low power contacts go, it's not that amazing. The first solid state radio contact made across the Atlantic ocean managed over 76,000 km per Watt. That was on 18 September 1956. You'll find the radio on display at the ARRL Laboratory, together with the bug and station log showing the contact between Chelmsford, Massachusetts and Copenhagen, Denmark between Gus W1OGU and Bo OZ7BO, on a radio made of two germanium transistors and built by Gus W1OGU, Al W1OSF and Dick W1UBC, who built the diminutive gadget on a lark to see if they could Work All Continents with it. If you can copy the 40 micro-watt CW beacon run by the North American QRP CW Club, you too can join in the fun. The current record stands at just under 22 million km per Watt when Bill W4ZV managed to copy the code word OMAHA from the N2XE beacon from New London, North Carolina. Just to be clear, we're talking about a signal that traveled the equivalent of 22 million km using 1 Watt of power. If you think that was amazing, Pioneer 10 managed to achieve 1.3 billion, that's 1.3 thousand million km per Watt in 2003. Mind you, that record was achieved with a slightly bulky antenna, the Deep Space Network. Are you ready for more? The current record stands at just under double the Pioneer 10 record, just under 2.6 billion km per Watt. That was achieved by Dick KL7YU and Bill W7BVV who made contacts between Alaska and Oregon in December 1969 and January 1970. A distance of 2655 km using one micro Watt. Yes, you can throw a Kilowatt at the problem, or you can take your time, do some work and have some fun with low power. You can call it QRP, or you can call it just enough to get the job done.

No wonder he tries to challenge the average (100 W) and the above average (1 kW) hams this time. Unlike him probably most of us know the correlation between power and signal strength. It is simple physics. And for sure almost everyone also knows that if NOBODY else is calling a certain station the chances are good that even with a QRP signal you are being heard. Even more so if the operator on the other side is skilled and has good antennas. Normally if we all would approach the hobby with the QRP attitude very few would manage to make a contact. With QRP attitude I mean I have never heard a QRP station using a stack of monobanders. Usually the antenna approach is the same as the power approach - MINIMUM! Nothing wrong with it and I like to try QRP as well if a signal is strong and not too many are calling however with minimum efforts on both sides especially under poor conditions even without competition it is often impossible to establish the contact or even hear each other. After all it is for a good reason that broadcast stations were and still running high power. Yes it is possible to communicate around the world with low power if conditions are good, competition is low or nonexistent so what is new about it? Right - NOTHING! 6 dBs are 4 times the power and "Life is too short for QRP" - that is not new either but nevertheless a valid attitude too................................. 73/Roger, DL5RBW -----Original Message----- From: elecraft-bounces at mailman.qth.net [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Ignacy Sent: Friday, September 27, 2019 5:38 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] We Need More Power The correlations between passionate writing and useful content is close to zero if not negative.

For what it?s worth, the phase/amplitude settings for opposite sideband null on both the KX3 (except for FL1) and PX3 (everywhere) were substantially different than the factory/default settings. Double checked everything.

YES! Only first quality connectors and adapters should be used. I run legal limit to resonant antennas fed with 50 ohm and 75 ohm coax and hard line. Amphenol 83-1SP connectors are the standard throughout my station. I use type N only on hard line for which UHF connectors are not available. I've NEVER experienced any symptoms of arcing in connectors. I HAVE seen lots problems caused by poor quality connectors and adapters, and by poorly soldered coax connectors when putting stations together for Field Day and similar operations. My rule: In North America, if the connector doesn't say Amphenol 83-1SP or have a MIL spec number stamped on it, it is JUNK. The same holds true for adapters. 73, Jim K9YC From xdavid at cis-broadband.com Fri Sep 27 14:54:32 2019 From: xdavid at cis-broadband.com (David Gilbert) Date: Fri, 27 Sep 2019 11:54:32 -0700 Subject: [Elecraft] We Need More Power In-Reply-To: <9af5c7b8-ec07-fe47-37b9-ab59ccbcc6a2@blomand.net> References: <9af5c7b8-ec07-fe47-37b9-ab59ccbcc6a2@blomand.net> Message-ID: <21e1b68e-6866-0df7-5c69-44297ef0bf31@cis-broadband.com> Stuff like this annoys me greatly because it takes anecdotal information and extrapolates it into a generalization.? More power isn't the solution to everything, but as a very extensive thread on one of the other reflectors (TowerTalk or Contesting, I don't remember which) recently pointed out, additional power offers the very best bang for the buck for almost any station once you get above some fairly basic antennas.? 10db from a used amplifier is awfully hard to beat for cost effectiveness ... even more so if you're space challenged and can't put up gain antennas. Besides, we're in sunspot hell right now and VK6FLAB's examples were from a totally different solar environment.? His 1956 example occurred during the best solar peak in our lifetime.? His 1969 example was also at a solar peak on 10m and I'd bet the antennas were impressive.? The night before Field Day one year I worked an FR5 station on the opposite side of the globe from here in Arizona with 5 watts to a crappy antenna with Q5 copy on both ends, but that was an anomaly and I had one of my worst FD scores ever the next two days.? Anecdotes aren't worth the keystrokes it takes to type them. They are interesting oddities and should be treated as such. I've done a LOT of QRP operating and it can indeed be fun, but as others have said many times, the effectiveness of the station and ability of the operator on the other end contributes as much or more to the success of the contact as does the supposed skill of the QRP operator.? I find it telling that QRP proselytizers always seem to tout being heard on the other end and rarely brag about how they dug somebody else's meager signal out of the mud. I run 5 watts for Field Day because the five points more than compensates for the weaker signal on domestic paths.? I run 50 watts for FT8 because I find that with my antennas I'm able to work just about anyone I can decode and I like saving the finals in my K3.? I run 100 watts for contests like NAQP and anytime I get the urge to compete in a low power category.? But if I want to work DX or score more points for my club in a major contest I don't hesitate to run the amp. Using low power purely for the sake of using power has pretty much the same effect as raising the noise level for the guy on the other end, and I really wish these sanctimonious odes to low power would just go away.? Communication is communication ... nobody goes to a hamfest or club meeting with a gag in their mouth. Dave?? AB7E On 9/27/2019 8:03 AM, Bob McGraw K4TAX wrote: > As found posted in another group.??

Never really gave those stories much credence but a number of years back I was doing some work on an 80m full size vert one summer.? Managed at one point to to reach up and touch a wire that was hanging off the vertical - and landed up on my butt from the jolt.? So that static build up thing is real.? Been using high value high power wire wound resistors for bleeding since. And a polyphaser to provide the discharge path in the event the voltage builds up too high from a nearby strike or whatever. The 1500 has PIN diodes for switching.? Generically speaking running a PIN diode switched amp without a spark gap on the coax to clamp spikes from whatever cause seems like tempting fate one step too close.? Maybe the 1500 has some internal protection - don't hear much about a lot of switching failure on the amp.? But a GDT pass through like a polyphaser is cheap insurance. PS:?

After experiencing multiple shorts of Polyphaser arrestors on high wires, I've switched to the arrestors that Array Solutions sells because 1) they provide a discharge path AND 2) because they are built in a manner that their GDT can be replaced. 73, Jim K9YC From kengkopp at gmail.com Fri Sep 27 15:30:39 2019 From: kengkopp at gmail.com (Ken G Kopp) Date: Fri, 27 Sep 2019 13:30:39 -0600 Subject: [Elecraft] RF chokes ...

Even with the transmitter shut down, unless there is a "DC ground" on the antenna, one shorts the tower to ground first prior to climbing on or off the tower. This was a big deal when the local power company rescued three folks from our 770 tower after it "captured" their hot air balloon! Bleeding off static electricity is a big deal.

First, an important clarification -- is it HUM (pure 50 Hz) or BUZZ (harmonics of 50 Hz)? You description sounds like hum. The important thing is that the causes are different. Hum is, indeed, magnetic coupling of the 50 Hz field to some loop in the audio wiring. Magnetic coupling is proportional to the area of the loop. Suggestions. First, get power for all interconnected equipment from outlets that share the same protective earth. Second, bond chassis-chassis of every piece of equipment in the audio interconnection path. Third, try to figure out what the loop is that is doing the coupling and reduce its area. In some recording studios where a strong magnetic field exists, the solution is to run shielded twisted pair audio wiring in close proximity to power wiring. Also try to find or eliminate the source of the magnetic field. In North America, neutral must be bonded to earth at one, and ONLY one point, usually where it enters a building. A second bond between neutral and the same protective earth can create a magnetic field. Is it possible that there is a second bond somewhere in your system, perhaps associated with power to your EME setup? The I/O board for the original K3 uses un-shielded audio transformers that are a sitting duck for magnetic fields. My neighbor K6XX is an engineer at Elecraft. When he was testing an early K3 prototype, he set it up almost on top of his 1.5 kW power amp. When he tried to run RTTY, The AF circuitry was set into regeneration by the 60 Hz field! The solution I suggested was a steep high pass filter for AFSK-A, and that solved it. Many years ago, a Chicago FM station whose engineers I knew well moved their studios from a location downtown to another location that is common to a TV studio with whom they had a relationship. When they first moved in, a strong magnetic field was coupling into the mic input transformers of their music mixing desks. The cause was an error in mains wiring -- the neutral for the distribution panel for the FM studio was exchanged with the neutral for a distribution panel feeding lighting in a different part of the building. 73, Jim K9YC From k2vco.vic at gmail.com Sat Sep 28 00:55:52 2019 From: k2vco.vic at gmail.com (Vic Rosenthal) Date: Sat, 28 Sep 2019 07:55:52 +0300 Subject: [Elecraft] RF chokes ... In-Reply-To: References: Message-ID: <848915E4-BF06-41E5-9BE0-C9908EE86191@gmail.com> This may or may not be a good idea. The impedance of RF chokes at multiple frequencies varies greatly, as anyone who has built a high power tube amplifier that covers 160-10 meters learns, sometimes the hard way. An open wire line used on several bands may present very high voltages at some points, which are different for different bands. So although Ken may have been lucky, your choke might go up in smoke, especially with high power. I calculated that the voltage at the end of my open wire feedline when I transmit is as high as 7kV on 40 meters, and I?ve seen the arcs to prove it! The usual 2.5 mh choke would probably explode with the first dit. I am using a pair of 20 megohm 10kV resistors that I got from Mouser as static drains, across homemade adjustable spark gaps.

I suspect this was partly my fault, trying to drive an amp known to take off and be generally unstable. I replaced the transistors and though at the time I had no hard and fast bias setting data the radio had worked fine until just now. Seemingly out of the blue and having made several short transmissions it just coughed on 30m and died. No output of any sort from 0-110 watts and no indication that any power is being produced anywhere. And unlike last time there is no output at the XVTR out socket either. I think I have this enabled correctly with XV1 on, XV1RF 144, XV1 IF 28 and the power set to L1.5. With the band set to 144 I would expect to see adjustable power up to 1.5dBm at the XVTR out socket but nothing doing on the direct input of my LP100A. Is this a known issue? I did measure the fets. Several hundred ohms drain to source and several kilohms gate to source in circuit. 13.8 volts on the drains and a couple of volts bias when keyed. So it seem more like a lack of RF drive. Where next?

Indications are the 7T transmit bias line is faulty somewhere. 7R is normal, 6.8-6.9 volts, but the transmit 7T line is very low, around 3.8 volts. I suspect this is the cause of no power out anywhere as the signal switching is not working. The 7T line reads a mere 20 ohms to ground so I suspect a failure somewhere in what hangs from that line. I guess I will just have to work through it. Maybe there are some known weak points someone might mention.

Short version C6 on the K3REF module had become a 12 ohm resistor. Longer version Finding the 7T line only going to 3.5 volts or so was suspicious. Measuring the resistance to ground of that line showed about 20 ohms where the 7 volts is generated at U11 on the RF board, very suspicious. The first step then was to remove any removable item that has a connection to the 7T line. That's most modules in the K3. Checking the resistance of the 7T line each time I removed a plug in module showed the fault to be somewhere on the K3REF module. The 7T line on this board goes to Q3 via R16, R8 and R9 and also to Q2 and U3 via L5. Measuring either side of L5 showed? lower resistance on the Q2 and U3 side, now around 12 ohms as opposed to 14 or so at pin 3 of P75. Focus then was directed at Q2 and U3 as likely culprits being active devices likely more prone to failure but removing Q2 showed no change nor did very carefully lifting pin8 of U3 and confirming no connection to L5. That left C6 as the remaining component on that line and its removal restored a much healthier 2.7k resistance to ground on that line as formed by R16, R8 and R9 around Q3 noted above. I don't have any of the microscopic 0.1uF capacitors used in this location, are they 0402? but I have a good selection of 1206 parts and being smaller than the chokes on this board I considered it a suitable change. The board mounts very close to the chassis so size is critical. All restored and the rig is back to normal working order. I don't know if these capacitors are prone generally to such failures but at least it was on a plug in board so easy to narrow down. So that was a fun Saturday afternoon for an hour or so, hopefully the radio will keep on working well now.

The longer original monitor cable was picking up magnetic fields and coupling into the audio transformers. The hum is now inaudible, I should mention that I was running the 2nd RX without AGC and used an attenuator so that the receiver was close to clipping. This shows up any nasties on TX audio. If I put the AGC on this masks such problems to some extent.

You can use direct frequency entry to jump to specific frequencies, or just tune the VFO. It can copy AM signals in either AM or SSB modes. Use the FIL switch to adjust the audio passband. You may want to set the VFO tuning rate (MENU:VFO CRS) to 5 or 10 kHz in AM mode. The KX2 also includes 100 frequency memories (with 5 character labels), 4 per-band memories, scanning, and channel hopping within grouped memories. All of these can be useful for general coverage. Refer to the owner's manual. Another feature unique is stereo audio. If you have AFX MD turned on, and you're using headphones or two external powered speakers, you'll get simulated stereo, which can be more pleasing to listen to than mono. The KX3 and K3S share all of the above features. 73, Wayne N6KR > On Sep 29, 2019, at 8:51 AM, Bob Conder via Elecraft wrote: > > Really basic question: what's the best way to set up the KX2 as a general coverage receiver?TNX de K4RLC Bob From wunder at wunderwood.org Sun Sep 29 12:26:00 2019 From: wunder at wunderwood.org (Walter Underwood) Date: Sun, 29 Sep 2019 09:26:00 -0700 Subject: [Elecraft] KX2 Gen coverage rcvr In-Reply-To: References: <905551147.818013.1569772262223.ref@mail.yahoo.com> <905551147.818013.1569772262223@mail.yahoo.com> Message-ID: <602D3A0F-7673-49AB-83F1-7B7C5656B2F4@wunderwood.org> I miss the ?GEN? band on the IC-756 that I used to have.

They'll appear as bands "XVTR 1" etc. above the regular bands as you cycle through them with the BAND switch. For example, suppose you wanted an SWL band covering approximately 6 to 8 MHz. Set up MENU:XV1 ON = YES, MENU:XV1 RF to 7, and MENU:XV1 IF to 7. This creates a virtual band display with an "IF" of 7 MHz. Since the "RF" is also specified as 7 MHz, the difference between the two will be 0. Just use BAND to select "XVTR 1" to tune this range. This will not have any effect on the normal 40 meter band settings. This technique is limited to bands close to those offered as IF selections (7, 14, 21, and 28 MHz). The same trick will work on the KX3 and K3. 73, Wayne N6K > On Sep 29, 2019, at 9:26 AM, Walter Underwood wrote: > > I miss the ?GEN? band on the IC-756 that I used to have.

Message-ID: The KPA500 offers a minimum fan speed setting which is settable by menu or serial command. Some posters have advocated setting a minimum fan speed higher than zero, presumably thinking it offers some advantage in thermal management. Does anyone have any hard data that shows that the KPA500 runs cooler, or with lower peak fan speed, when minimum fan speed is set above zero. Running a rigorous test may not be easy since it would seem to require the same ambient temperature, same finals starting temperature, same TX periods, and same antenna system load. I'm curious because, before CQ-WW-RTTY I configured my KPA500 to set min fan speed to 1 at start of TX and reset min speed to zero 30 seconds after stop of TX. Of course the fans ran faster than min speed during TX but I don't have any feel for whether the higher speeds were any more protracted than before the min speed change. Please share you experience of using min fan speed greater than zero, and any data if you have it. 73, Andy, k3wyc From jim at audiosystemsgroup.com Sun Sep 29 23:05:14 2019 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sun, 29 Sep 2019 20:05:14 -0700 Subject: [Elecraft] KPA500 - Advantage of min fan speed?

Lots of experience, but I've never bothered to take data. I used my KPA500 (replaced by KPA1500) a lot for WSJT modes on 6M. The KPA500 fan gets pretty loud after 15-20 minutes of near constant calling on FT8 or MSK144, but it takes a lot longer to get that way if a higher minimum speed is set. The KPA1500 works the same way, except that it gets a LOT LOUDER at LOT sooner. Neither amp is noisy enough to be an issue on CW or SSB, even with fairly heavy HF contest operation. I used the KPA1500 for the first time in a RTTY contest this weekend. I started hearing the fans speed up after 10-15 minutes of CQing with not many responses, but they never got anywhere near the SCREAMING level they hit with digital on 6M. The fan noise is tolerable because I do 100% of my CW and SSB operation with headphones, and for SSB it's a Yamaha CM500 with an attached boom mic. And for serious RTTY contesting, I'm running SO2R, wearing a headset with one ear dedicated to each radio to help me keep track of what's happening on each radio. The significance of 6M is that both amps are least efficient there. 73, Jim K9YC From va3mw at portcredit.net Sun Sep 29 23:05:10 2019 From: va3mw at portcredit.net (Michael Walker) Date: Sun, 29 Sep 2019 23:05:10 -0400 Subject: [Elecraft] KPA500 - Advantage of min fan speed?

May be due to a system change. Before it was really good! I own equipment ( 3xK3S, 3xP3, 1xKPA500 etc.) Therefore I turn to this group to be able to fix my K3S TX by myself. Sending the unit for repair to Italy is no option because of crazy VAT there ( HB9 no EU). How is your equipment operating ? K3S # 10490 factory assembled is now not TX working at all, based on IMD 3 (24dB, basically on all bands) and too low output problems. I try to troubleshoot/repair it and need further supporting technical info. I took out the 100W PA , replaced it with an older K3 module I had -> no improvement. If only running the 10W module the IMD is bad and I have only limited output. Analyzing the output from XVERT out BNC the signal is clean and about 1mW/50Ohm. 1) It would be helpful among others to receive info on the DC voltages ( Bias etc.) in the 10 and 100W module. In order to analyze the bias voltage/ current technical info is needed. 2) Is there any good way to check the QSK diodes? I want to make sure the diodes are working well. Should I replace them? I did measure it at XVTR OUT BNC. Output level about -1dBm to 0dBm into 50 ohms. Turning on the 2 Tone (Tech MD on ) and watching on the spectrum analyzer HP 8591E ( all functions auto/ cal. ok) with 10 dB 50 Ohm external attenuator shows a signal (2 Tone) which looks very clean down to at least 45 dB to almost 50dB on each side. Basically there is no difference on 160 or 80m or 40 . I can however not see expected side products (IMD3) here. May be the signal is just very good here ( Span e.g. 10kHz, sweep 10 sec) . In all measurements the LPA was set to about 11 watts connected to 50 Ohm DL anyway-probably disabled by SW . After resetting KXV3B to normal IMD3 at PL output -no 100W engaged - very bad again with about 10dB worst case. My conclusion there is again a problem in the new LPA (10W). What is your analysis? When I happily replaced the 10W/100W module last year (based on returned old once later , nice service!) all looked fine and then back to same problem. Thanks for any hints from the group .

I never worried too much about them since the Elecraft guys are pretty smart people and likely have done a lot more research on this than most of us." That's possible but they only gave you half the information. The thresholds you quoted are for increasing temperature. The fan speed step down thresholds are lower than the step up thresholds. (I have experimental data for fan speeds up to, and including, 5 but have never seen 6 except when I set min speed to 6 to hear how loud it was.) I measured the fan speed thresholds over a year ago but that information doesn't answer the question about any operation advantage of running min speed greater than zero. 73, Andy, k3wyc From donwilh at embarqmail.com Mon Sep 30 13:28:25 2019 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 30 Sep 2019 13:28:25 -0400 Subject: [Elecraft] KPA500 - Advantage of min fan speed?

Specifically for the amp, if you run the fan speed minimum at 1, it will heat to the 55 degC threshold more slowly before switching to level 2. Of course, from there on up to higher temperatures, there will be the same time period between the higher fan speed steps. In other words, the fan minimum will NOT shift the entire range of thresholds, but it WILL delay the time to reach the level 2 threshold. 73, Don W3FPR On 9/30/2019 1:13 PM, Andy Durbin wrote: > > I measured the fan speed thresholds over a year ago but that information doesn't answer the question about any operation advantage of running min speed greater than zero. > From rmcgraw at blomand.net Mon Sep 30 13:31:34 2019 From: rmcgraw at blomand.net (Bob McGraw K4TAX) Date: Mon, 30 Sep 2019 12:31:34 -0500 Subject: [Elecraft] Creaking KPA-500 In-Reply-To: <45C0E6E9-0EB2-4F0D-A40B-BD32FD3AEED6@comcast.net> References: <45C0E6E9-0EB2-4F0D-A40B-BD32FD3AEED6@comcast.net> Message-ID: <62017b26-da15-2d64-660e-eef4f31d2c34@blomand.net> Phil et al; My factory built KPA500 did a good be of cracking and popping for 3 or 4 months when first received.??

In-Reply-To: References: Message-ID: >From a physics standpoint, heat is radiated from an object either by direct radiation of heat into space (photons) or by transfer of heat to an adjacent object with lower temperature. For heat transfer to another object, the amount transferred depends substantially on the heat absorbing characteristics of the object. Some objects are natural insulators and will result in little heat transfer. Air is not an insulator but it is not as effective as water, which is 24 times as heat absorbing as air. The surface area of contact is also important. Moving air across a hot surface increases the exposure of cooler air to the hot surface resulting in faster cooling. In other words a faster fan will always cool more than a slower fan. -----Original Message----- From: elecraft-bounces at mailman.qth.net On Behalf Of Don Wilhelm Sent: Monday, September 30, 2019 10:28 AM To: Andy Durbin ; elecraft at mailman.qth.net Subject: Re: [Elecraft] KPA500 - Advantage of min fan speed?

In-Reply-To: References: Message-ID: When running RTTY with the KPA500 I no longer have, I noticed that, with a minimum fan speed greater than zero, the temp tended to fall lower during RX periods than when the min speed was zero. During the subsequent TX period, having started from a lower temp, it would not rise as high, keeping the fan speed one step lower by the end of the TX period.? I assume this was because there is significant thermal "inertia" in the amplifier but thermodynamics was never my best subject.? RTTY operation tends to have a regular-ish pattern of on-off, I never noticed the fan going to high on CW.? I suppose the FT modes would present an even more regular pattern. All anecdotal Andy, I didn't bother to take any data. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/29/2019 7:38 PM, Andy Durbin wrote: > The KPA500 offers a minimum fan speed setting which is settable by menu or serial command.

Then it won't matter and you do not have to sign onto several web based accounts. I currently have 11 accounts that are handled by my email client (Thunderbird). All incoming mail is sorted via filters into separate folders under my inbox, so I have only a small amount of inbox investigation and arrangement to do. As a result I have my own personal "digest" on my computer. I shudder to think how long it would take me to sign into each email group using webmail. Most of my accounts are handled as POP3 mail, and yes, I do look at my email on more than one computer. I just tell Thunderbird to leave a copy of all emails on the server for 7 days (unless I delete them), and I can see all my email on any computer as long as I download the email on each one at least once a week. To me all my accounts look the same whether QTH.net, or groups.io or gmail or other. I use plain text with all of them - no problems. I do regularly delete emails that are more than 6 months old - but I have to do that manually. 73, Don W3FPR On 9/30/2019 2:48 PM, Lynn W. Taylor, WB6UUT wrote: > Reflectors are like CW.?

Each of the reflectors to which I belong that has moved to groups.io is much more pleasurable to use...particularly is you are like me and use Digest mode (I feel the heat coming!). And I eschew email clients because I get email via 4 different hardware platforms: Mac OS, Win,Android, and iOS. So, Yes, I use a Web "client", aka browser, on most of those devices and it works quite well. It's possible that moving to groups.io would make the Elecraft archive difficult to transition; I don't know, but that may be a consideration. 73 --- Ted WA3AER Message: 6 Date: Mon, 30 Sep 2019 14:22:12 -0400 From: Neil To: elecraft at mailman.qth.net Subject: [Elecraft] A First Class Company Message-ID: <5D9247D4.1070603 at gmail.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Yes indeed, Elecraft is a FIRST CLASS company.....Unfortunately with a third world country reflector (just my opinion) Other reflectors use the user friendly IO service.

In-Reply-To: References: , , Message-ID: Don, Two test cases - Case 1: Ambient temperature 28 deg C, KPA500 OPER mode but no TX in over 12 hours, fan speed zero, PA temp 35 deg C. Case 2: Ambient temperature 28 deg C, KPA500 OPER mode but no TX in over 12 hours, fan speed 1 run for long enough to stabilize PA temperature, PA temp 29 deg C. Fan 1 continuous operation has pre-cooled the KPA500 PA by 6 deg C (measured data). It's obvious that that the start of the the first high power "run" cycle will have a later onset of fan 2 if the KPA500 has been pre-cooled at FS 1. What is not obvious is whether there will be any sustained advantage if the "run" continues. If the "run" never allows the temperature to drop to fan speed 1 there would appear to be no operational advantage to the pre-cool at fan speed 1. For a S&P duty cycle each TX would likely have delayed fan speed increases. However, that advantage has to be offset by the noise of fan 1 when no cooling was required.

Andy, Physical fact related to any heat dissipating object -- if you apply an air stream across the object, it will not come up to a given temperature as quickly as having no air stream across it. Specifically for the amp, if you run the fan speed minimum at 1, it will heat to the 55 degC threshold more slowly before switching to level 2. Of course, from there on up to higher temperatures, there will be the same time period between the higher fan speed steps. In other words, the fan minimum will NOT shift the entire range of thresholds, but it WILL delay the time to reach the level 2 threshold. 73, Don W3FPR From KY5G at montac.com Mon Sep 30 21:28:27 2019 From: KY5G at montac.com (Clay Autery) Date: Mon, 30 Sep 2019 20:28:27 -0500 Subject: [Elecraft] A First Class Company In-Reply-To: <953D0658-00F6-4128-A381-1083FC8E8D2B@triconet.org> References: <5D9247D4.1070603@gmail.com> <953D0658-00F6-4128-A381-1083FC8E8D2B@triconet.org> Message-ID: <4a15d47e-6687-0f98-1558-9654952ffe0d@montac.com> Mmmm... care to offer some amplification of that statement.... along the lines of WHY?

You can always start your own reflector and run it the way you want.
