Re: [Elecraft] K4 Kit???
Not in my experience. Chokes are inductors and, together with stray capacitance, can create unwanted resonances and accompanying parasitics. Resistors just bleed the charge off an otherwise nearly infinite input impedance which is the whole idea in the first place. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County **"Nearly infinite" is not a really good term mathematically, but it's short and conveys the idea On 5/18/2020 4:39 PM, W2xj wrote: Better to use a choke Sent from my iPad On May 18, 2020, at 6:47 PM, Fred Jensen wrote: I believe Elecraft equipment has static drains built in but I always put a resistor in a PL-259 plugged into one arm of a coax tee with the antenna on the other arm, on the connector on the radio.

[Elecraft] More parts (was K4 Kit??)
"(More parts = more fun.)" You must miss the days when tag strip construction was the norm. I prefer the equipment to be smaller than the room it has to fit in. I also prefer to be able to lift it. My first commercial RX was an AR-88D and it almost failed both tests. Highly integrated circuits have done wonders for equipment capability, size, and weight. Can you imagine doing DSP with 1960's technology? A low power computer filled a large room in those days - lots of parts though.

Hi Drew, Rather than a parts count -- an esoteric parameter I get paid to worry about -- I'll give you a qualitative breakdown. Even a basic K4 is the equivalent of: K3S + P3 + KRX3 (for dual-watch purposes) + KXV3 + KDVR3 + Linux/Intel MPU + large touch screen + external monitor adapter (like P3 SVGA, but HDMI) + more controls, more antenna jacks, more digital I/O ports, and all the DSP/ADC/DAC/FPGA hardware needed to create a modern SDR. It also has a multi-processor architecture with unlimited potential for future expansion. Of course there are economies related to it being an SDR, such as no crystal filters in the basic unit. >From this you could take an educated guess. 73, Wayne N6KR > > 73, > Drew > AF2Z > > > On 05/18/20 11:12, Wayne Burdick wrote: >> We certainly appreciate the interest in a K4 kit.

My question was techie-rhetorical. We should not trust ANY reports that xxx product is RF quiet unless we know a LOT about proximity of noise source to antennas, the sum all of the other noise that could be obscuring it in the observer's receiver, and that info for ALL ham bands. A meaningful test would be waterfall plots from an SDR with a small loop antenna that can be placed in proximity to the potential noise source. This doesn't require lab-quality testing, simply a waterfall covering the frequency range of interest.

Re: [Elecraft] New Astron Switching PS RFI?
I had two of them and both had RFI, on 12 meter band, it was a broadband noise of S2 or so. If your noise level is higher than S3 then you may not even notice it as it was noise similar to the noise floor, as wide as the band. Had other "spots" on other bands that had hash but not too bad. Have tried many switchers and every one I have had put noise someplace, if you mention that on this reflector all you get is a tirade of people with S5 to S6 band noise levels screaming they hear nothing, they are correct they hear nothing. Elecraft even admits the switcher they sell has noise. I have a very very low external noise level at this QTH, so linear supplies are the only way I am sure to be free of noise, birdies, and crap internally. YMMV Merv K9FD EME on 6m, terrestrial on 2 & 432 with antennas directly above the shack. Noise floor very low (usually) so anything added very apparent. I haven’t noticed anything at HF. The only problems I’ve had at HF were a particular model of Samsung monitor, and PGE powerlines where HV ran on the old ceramic insulators.

[Elecraft] PX3-KX3 display question
My KX3-PX3_KXPA100 system works perfectly, however I cannot understand the PX3 display. On either USB or LSB there is a significant, narrow signal spike which tracks the KX3 frequency. On either USB or LSB it is at the edge of the cursor where the carrier (suppressed) would be. There is no tone as I tune across it and it does not interfere with operation. The waterfall does show a narrow trail. If I change the XFIL from FL1 to FL2 then the spike moves to the center of the new, narrower passband. On CW it is in the middle of the passband. Is this spike normal or am I setting something incorrectly? I can send photos, if needed.

There's an intermediate approach that many of our customers have used over the years: get an assembled basic radio, then install option modules yourself as required and as time/availability permits. Option modules will come with detailed assembly instructions. 73, Wayne N6KR > On May 17, 2020, at 2:14 PM, Charlie T wrote: > > Yep, just more fun to "build" one eh? > > Actually, I'm just plain "Cheap" and hoping to save a few bucks on a kit > version. > However, recent Elecraft kits are more like erector sets, but I DID build a > K2 complete with soldering stuff. > > 73, Charlie k3ICH > > > > > -Original Message- > From: elecraft-boun...@mailman.qth.net On > Behalf Of Steve KC6ZKT > Sent: Sunday, May 17, 2020 4:34 PM > To: elecraft@mailman.qth.net > Subject: Re: [Elecraft] K4 Kit??? > > On 5/15/20 8:08 PM, Bill Frantz wrote: >> And I'm still waiting for the kit version. > Same here.

[Elecraft] An Unusual KPA-500 Failure - That Wasn’t ...
I thought the group might find a recent KPA-500 troubleshooting experience interesting - and possibly be of help with future troubleshooting efforts. For reference, my station consists of a TS-890 followed by a KPA-500 and a KAT-500, that interfaces different wire antennas depending on the operating band. One Friday night after dinner, I headed to the ham shack to check out 160M. Since it had been raining I needed to check the antenna SWR. After completing a KAT-500 (KAT) tuning cycle at low power, I had a new tuning solution and switched in the KPA-500 (KPA) for confirmation. I started at low power and slowly increased the power level. At around 100 watts output from the KPA I was rewarded with what I call the “Allen-Bradley” smell, a slight cloud of smoke and a KPA low voltage alarm! I immediately cut power and tried to reset the KPA alarm but couldn’t by cycling the power off/on. So I unplugged the KPA from the AC power. After reconnecting the power and turning the KPA on, the alarm was gone. I repeated the tuning process, with almost the same results except the smell and smoke were more noticeable. At this point I took the KPA completely off line, disconnecting all control and RF connections, and raised the power out level of the TS-890 to 90 watts, which then confirmed normal operation via the KAT. At this point I began to think about returning the KPA for repair and wondered how long it would take to get it back, considering COVID-19 issues. For some reason I decided to try the KPA500 - KAT500 pair one more time. This time I moved closer to the KPA500 to try to get a clearer idea of where the “smoke” was coming from. I slowly raised the power one more time and the KPA shut down just like before, but this time I noticed the “smoke” was coming from what looked like the rear of the amp. I moved the KPA and noticed the smell was still very strong - and at the rear of the KPA. It was then I noticed that the AC line surge suppressor the KPA was plugged into, in a wall socket directly below the back of the operating table with the KPA, was the source of both the smell and “smoke”. I bypassed the suppressor and was relieved when the KPA returned to normal operation. Somehow, when the current draw through the suppressor reached a certain level, failing internal suppressor component(s) overheated and presented a line voltage drop to the KPA500 sufficient to trigger the internal low operating voltage alarm. With the suppressor located directly behind and below the KPA, it seemed like the smell and smoke were coming from the KPA - and the KPA was failing since the KPA low voltage alarm activated. So of course, always check to make sure the equipment you’re troubleshooting is actually “plugged-in” (following troubleshooting safety guidelines) - but also check to make sure any in-line power surge suppressors are working correctly. 73, Bob, W3RW __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K4 Kit???
Yep, just more fun to "build" one eh? Actually, I'm just plain "Cheap" and hoping to save a few bucks on a kit version. However, recent Elecraft kits are more like erector sets, but I DID build a K2 complete with soldering stuff. 73, Charlie k3ICH -Original Message- From: elecraft-boun...@mailman.qth.net On Behalf Of Steve KC6ZKT Sent: Sunday, May 17, 2020 4:34 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K4 Kit???
