Re: [Elecraft] High vertical
For what it's worth, the R6000 is very different from the R8. On 20 Oct 2014 05:48, tom...@videotron.ca wrote: Hi Robert,I can't seem to find any other messages in the reflector about this topic. But in any case I have owned both a Cushcraft R6000, and a HyGain AV620.I used both for at least 6 months before moving to a cushcraft ma5b mini beam. Both antennas seemed to offer similar performance. In this regard, I would give the edge to the hy-gain. Both were excellent for dx, I made many qrp qso's from Montreal to australia. The cushcraft had one annoying feature: The minute it rained or snowed, the resonance went far off where it was when dry. 200khz on 20m for example. The elecraft tuner took care of it but it was annoying. The hygain has a lot of threaded rods which need to be adjust to reach resonance. These rods are prone to seizing the nuts on them. But once they re set the antenna never shifted in resonance. The hygain brought me up to 200+ DXCC's. But I can tell you this: Both are no substitute for the MA5B. Both are extremely noisy. The MA5B gives two 2 S unit improvement as a minimum in almost all cases, but the noise floor dropped 15dB. Anyways, they both are good antennas, but I would suppliment them with an active antenna and a noise phaser to null out the noise sources, which improves them considerably. Hope this helps.

[Elecraft] KX3 - dBV question
Hi, I have been playing around with the dBV-Feature of my KX3 for some time. I understood how to use it and that it measures a relative input level into the AF stage of the KX3, but my question is if there is any kind of data processing involved, in other words: the display is updated roughly once in a second, and my question is if is the input level to the AF stage just being sampled once a second, is the value being displayed something like the peak level that occured during this one second interval between two updates of the value or is something like the average of the signal level during this second being displayed? We have been discussing the system advantage of CW compared to SSB in the german QRP facebook group, I tried to measure my personal ability to copy weak SSB and CW signals by using this dBV display, but am not sure, if I can compare the values directly, since I do not know how the data is being generated and processed. Maybe someone on the list or at Elecraft can help me out.

Re: [Elecraft] KX3 - dBV question
Hi Ralf, Lyle explained how the dBV value is derived. It's a pretty useful measurement. One way to use it is to disable AGC, then measure different signal levels. This makes dBV a linear measurement, up until the signal level causes hardware AGC to activate. Be cautious with your hearing when AGC is disabled. 73, matt W6NIA On Mon, 20 Oct 2014 01:45:24 -0700 (PDT), you wrote: Hi, I have been playing around with the dBV-Feature of my KX3 for some time.

[Elecraft] P3 shows vertical green stripes on waterfall
Hello all, I am trying to figure out why our P3 panadapter sometimes but not always shows a group of vertical green stripes that cover about 1/6 of the width of the screen. These stripes are not related to RF frequency because if I switch bands they remain in the same location. If I remain on one band and twirl the VFO knob, real radio signals move into the green stripes but the stripes themselves are immobile. Sometimes these are not there at all. Sometimes they are near the left of the screen, more often toward the middle. Wayne gave some instructions for investigating this on PX3,but this is P3. Any ideas? Am I correct that these cannot be related to real RF interference due to the above facts? Wouldn't real RF be frequency-related? We do sometimes get RF interference that shows as periodic narrow lines on the waterfall, but these wide stripes are different. THANKS!

[Elecraft] KX3/PX3 RIT Question
When I use the KX3 RIT, I get a red 'transmit' cursor on the PX3 which is great. However when I press the 'B' knob to reset the RIT to zero, the RIT resets, but the red cursor remains on the PX3 until I slightly turn the 'B' knob, then it disappears. Just turning the 'B' knob (without pressing it) to reset the RIT to zero gets rid of the red cursor as soon as zero is reached. Everything works fine with Split.

There has not been a new product from either of these makes in many years.I am still glad though that the likes of my first commercial antenna a 14 AVS now 14 AVQ is available.The Hy-Gain mono-banders were not such bad antennas and at least one can still install them. Yes, maybe quality has dropped but they would not be with us at all but for MFJ. 73 Doug EI2CN -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Lynn W.

[Elecraft] K3 on 40 meters
I have noticed that signals on 40 meters do not appear very strong on my K3. The audio and signal strength is very low. Other hams in the area hear signals S9 +5 while these only register S1 at best on the K3. Antenna type and height are almost identical as I have. Attenuator is not on and noise reduction has minimal effect. Turning up the RF gain does not help. Signals on other bands seem to be normal. Has anyone experienced this?

Check to be sure you don't have the RX antenna input selected on 40m without an RX antenna connected. This feature is remembered per band.

Re: [Elecraft] K3 on 40 meters
Gene, Do you have the correct antenna input selected? ANT1/2 if the KAT3 is installed, or RX ANT if the KXV3 is installed. It sounds like you may have the RX ANT selected rather than the main antenna. That is a per-band setting, so it would only be a problem on one band. 73, Don W3FPR On 10/20/2014 7:09 PM, Gene wrote: I have noticed that signals on 40 meters do not appear very strong on my K3.

Re: [Elecraft] K3 on 40 meters
Dear Gene, :)) Please note that at last count 98.91% of all K3 owners have pulled that wrong antenna per band stunt on themselves and spent at least an hour looking elsewhere for the problem. 95% of the 98.91 have done it twice. 90% of the 95 have done it three times or more. 50% of the 90 have trouble remembering that for more than six months at a stretch and do it again on a more or less semi-annual basis. Those of us who have officially become olde phartes, no longer report such events to the statistical data base, and have no intention whatsoever of telling anyone how many times we *really* do that to ourselves. The price for all that wonderful K3 technical flexibility. In any event, welcome to the Royalle Fraternitie of RX Antennae Selection F***-Ups. You have arrived. 73, Guy.

Re: [Elecraft] K3 on 40 meters
Aside from the well known fact that 86.41% of the adult population makes up their own statistics, I'm part of Guy's 98.91%. 30m was dead and infinite SWR. Wayne called me, said Let's start with the easy part ... and everyone can finish the story. I've now done it twice on my K3, second time I knew what to check. I had this same problem on 2m with my FT-847 on 2m FM, couldn't raise the local repeater ... 2m coax connected to the 6m connector, nothing in the 2m connector. No one called me from Japan. :-(( 73, Fred K6DGW - Northern California Contest Club - CU in the 2015 Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 10/20/2014 5:18 PM, Guy Olinger K2AV wrote: Dear Gene, :)) Please note that at last count 98.91% of all K3 owners have pulled that wrong antenna per band stunt on themselves and spent at least an hour looking elsewhere for the problem. 95% of the 98.91 have done it twice. 90% of the 95 have done it three times or more. 50% of the 90 have trouble remembering that for more than six months at a stretch and do it again on a more or less semi-annual basis.

[Elecraft] Coiled Coax Choke
I am thinking of adding a coiled coax common-mode choke to my system. Presently it goes K3-KPA500-KAT500 then 100 ft coax to the base of an inverted Vee¹s center support pole (collapsible fiberglass), then 30 feet up the pole to a 1:1 balun feeding a fanned 10-15-20 Vee. The idea, for a couple of reasons, is to put the choke at the base of the pole, something I haven¹t seen discussed in the literature. Two questions I am wondering about: 1. The choke would be 100 feet from the tuner and about 25 feet from the antenna/balun. Probably not as good as having it right at the Vee, but is that compromise worth while? 2. For appearance sake I am thinking about winding the coax around the base of the support pole. It is 2 inches in diameter but I could slip a 3 inch PVC over that section to increase the diameter. Anyone know an algorithm for determining the number of turns in the winding if I do that? I would be much obliged for any thoughts and suggestions . . . Tnx!

Re: [Elecraft] Coiled Coax Choke
A choke in the middle of the transmission line could help, but the usual configuration is a current balun at the antenna to reject common-mode signals at the source, plus an optional choke at the entrance to the shack to reject noise picked up by the outside of the coax shield. A coiled-coax choke works OK, but you get the best rejection from a toroid-based choke or balun. I’ve had good results with the ones from Balun Designs (http://www.balundesigns.com). Putting a Balun Designs balun at my dipole dropped the noise by 6dB. I highly recommend K9YC’s super-detailed explanation of fighting noise in your antenna and elsewhere in your shack. http://audiosystemsgroup.com/RFI-Ham.pdf wunder K6WRU CM87wj http://observer.wunderwood.org/ On Oct 20, 2014, at 7:28 PM, Dauer, Edward eda...@law.du.edu wrote: I am thinking of adding a coiled coax common-mode choke to my system.

If you're having RFITS problems [RF In The Shack], there are better and far less visually obvious ways to suppress that using common mode ferrite chokes than winding up your coax around anything.

[Elecraft] FS: K2 QRP 100 watt amp/tuner in EC 2.
I'm downsizing since retirement earlier this year, will be on the road with the travel trailer. These item need a new home instead of sitting packed away. I have my KX3, PX3 along with the KXPA 100, it all fits nicely in the trailer. The K2, s/n 6576, was built in late 2011 by Dale Putnam WC7S, with the complete Rework Eliminator kit. Installed in it are SSB option, Antenna tuner, KDSP2 filter with clock, KIO2 RS-232 interface, KBT2 battery kit, no battery.There's an unbuilt noise blanker. There's a weighted VFO knob installed, and an extra top cabinet panel with speaker installed. All the manuals included, along with a MH-2 hand mic and headset adapter. There's two unopened Rework Eliminator kits, KXPD1 clamp for the KX1 paddles to mount to the K2 bail, a cable for connecting the NUE-PSK modem (modem not included). In a separate enclosure is the KPA/KAT 100 amp/tuner with cables to hook to the K2. Both radio and amp are in great condition. Asking $1500.00 for the package, new this would cost almost $2400.00.. I will double box and insure, and pay the shipping, only lower 48 thou, no overseas. Paypal, or money order works for me. You will get two boxes with the K2. As with all used electronic equipment, there's no return or refund. You will get working radios when they leave me. Contact me off-line at ekac...@yahoo.com mailto:ekac...@yahoo.com, or call my cell and leave a msg. 520-490-5395. ( I don't always hear the cell with my hearing aids) __ 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
