[Elecraft] Conditions, shmonditions: DXing anyway
Tonight I heard a very weak CW CQ on 7.007 MHz right around sundown -- LA1MFA (Norway). With the filtering on the K3S dialed down to 100 Hz, 30 Hz audio peaking filter (APF) turned on, and the noise blanker optimized, he was readable. I called and he came right back to me. I would normally have tried this at 10 watts first, but something about the tenuous nature of conditions these days had me cranking the power up to 100 W from the get-go. Despite requiring "full" power to make this contact, it was a reminder that DX is out there if you tune slowly On a related topic, I discovered that as a guy of a certain age, 400 Hz may be a better pitch for copying weak signals than my usual 550 Hz. This could be a well-understood psychoacoustic phenomenon, but it came as a pleasant surprise. 73, Wayne N6KR __ 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
[Elecraft] [K3] Feature request - based on the KX2
The KX2 now allows 4 separate programmable functions when the "PFn" key is pressed. That would be a nice feature on the K3 for the PF1 and PF2 buttons. There are many times now when I disconnect the USB cable from the rig as I have found a large (10 to 20 dB) increase in noise floor on some bands when the cable is connected. (I have tried a few things to fight the noise floor increase but no success so far). 73, John W2XS -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@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
[Elecraft] Subject: Re: KPA1500 - Static IPv4 address
A better way, perhaps... Leave DHCP enabled in the PA and any other equipment, but make a written note of the PA's LAN port MAC address. (And that of any other LAN connected device you have.) In your router (or other DHCP providing gadget) look in it's setup for "address reservation" or similar menu item (or RTFM to find it) In there you can usually identify all currently connected devices, if not by name (if the device reports that) but by MAC address, and you can then tell the router (or whatever) to always assign the same IP address to that MAC address. (If the device is not connected, then that IP address is not assigned to anything else, as it is reserved for that MAC address alone.) In your PC (whatever type) you can also edit the "hosts file" to assign a known IP address to a "name", making things even easier. Lot's on the interweb about that. (On Windows, you will need Admin rights to write to/save that file, on Mac/Linux you'll need Root privileges, so take care. Make a pre-edit backup, just in case!) Job done. I (and many others) do this, for such items as NAS servers, dedicated special purpose PC's, printers, other servers, Raspbery Pi's (used as VPN endpoints) IoT and and LAN to Serial port devices. It all "just works" seamlessly. But, do keep written notes as to what you did, as you will need that sometime in the future. Hint! If you don't want to mess with your ISP's supplied router, there is nothing whatsoever preventing you from using something like the old Linksys routers as dedicated "Shack" routers, that you have 100% full control of. If at some point your ISP changes, nothing in the shack needs to change, as that box is just another device on the new router's LAN side. Many pre-used domestic routers can be used for this sort of thing, and just about all commercial SoHo routers too. Especially those that can take the WAN side by a network port, not just cable or xDSL. Lastly, I don't know what Elecraft use for their LAN ports, but if they are the common Lantronix embedded devices, then Lantronix have a "device installer" program, that will reach out find and identify the IP address of all such devices on your LAN. You'll still need to know the device's MAC address though. Find it on their website. (Google will tell you where.) That's a Windows tool, there are other (somewhat advanced) ways of doing the same from Linux, I have no knowledge of if that can be done with a Mac. 73. Dave G0WBX.

Re: [Elecraft] loss of RX sensivity
Hi all! I'm a member of some similar lists. Every time somebody asks for help of some issue, the biggest count of "advices" distrace far away of the original subject. Are U sure that zillions of ways how to tighten A certain connector or wisdoms alike, are any real kinda solution. Seems that the real fact goes 2far OFF-TOPIC! To unveil, I have caught myself undeliberately pressed the antenna selector swith, being too lazy to read the display. Fortunatelly I havent (yet) dismantled any of my gear to find the real reason. :-D 73 & CU Penna OH2G elecraft-requ...@mailman.qth.net kirjoitti 18.09.2018 klo 21:45: Send Elecraft mailing list submissions to elecraft@mailman.qth.net To subscribe or unsubscribe via the World Wide Web, visit http://mailman.qth.net/mailman/listinfo/elecraft or, via email, send a message with subject or body 'help' to elecraft-requ...@mailman.qth.net You can reach the person managing the list at elecraft-ow...@mailman.qth.net When replying, please edit your Subject line so it is more specific than "Re: Contents of Elecraft digest..."

The pressure is provided only by the tightening of the threaded portion of the PL259. I ask you - just how much resistance can be expected if you just touch two ends of wires together without further positive contact? The "insulating spacer" is any oxidation on either the SO239 or the PL259. That is why I like silver plated UHF connectors. They may look a bit corroded, but the silver oxide is conductive even though it can appear brown or black. If you are shopping for UHF connectors at hamfests, avoid all those nickel-plated ones that a not Amphenol, but flock to those that are oxidized, and silver plated with Mil Spec designations on them. 73, Don W3FPR On 9/17/2018 6:39 PM, ANDY DURBIN wrote: " the threads of the PL259 are providing the only contact with the SO239" In the connectors that you are mating how do you prevent contact between the end face of the PL259 body and the end face of the SO239 body? You would need an insulating spacer for your statement to be true. __ 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 wun...@wunderwood.org -- Message: 2 Date: Mon, 17 Sep 2018 16:46:28 -0700 From: Wes Stewart To: elecraft@mailman.qth.net Subject: Re: [Elecraft] loss of RX sensitivity Message-ID: <4edb4fb7-4dec-3b77-379d-7c147885a...@triconet.org> Content-Type: text/plain; charset=utf-8; format=flowed This is one of those, "it depends" situations.? Depending on the location of the two center conductor insulators in the plug and socket, the serrated (toothed) surface of the female connector might well contact the mating plug surface, if there is a gap
