Re: [Elecraft] CP1 vs other directional coupler
It would be pretty easy to modify the CP-1 to use SO239 connectors and mount it in a box. I would do it while building the board - drill four holes in the corners for mounting, mount the SO-239s on the box and wire them to the board. But, I would also keep the BNC connectors for the test connections since Scopes and frequency counters usually have those for input jacks. Interesting project. My CP-1 is built with the BNC connectors and usually have adapters attached for the TX IN and Out as needed. It’s a very handy board! - Jack, W6FB > On May 28, 2017, at 10:23 AM, Mike Markowski wrote: > > I'd like to get a directional coupler to, among other things, monitor my > transmit signal on a scope. > > The Elecraft CP1 kit is priced well, but I'd want it in a metal box with > panel mount connectors, SO-239 for the main RF path.

Re: [Elecraft] List Overload
Ted and all, I am in agreement with you. There is benefit in many OT conversations, and thankfully Eric allows it. We learn many things about ham radio in general as well as how it applies to Elecraft radios (even if it is only about operating/conditions at the time). There are many OT discussions about things related to the hamshack in general including "I have RF-in-the-shack" that relate to our use of Elecraft gear. Discussions of that nature are for the edification of all Elecraft users. The problem is that there are many "me too" responses, or the conversation becomes opinionated or personal. We can all learn a bit from those OT discussions, but be cautious not to overdo it else Eric will shut it down. If the discussion turns to specifics of one or two persons, take it off-list. Or if the subject is not of interest to the general ham community, take it off-list. The list rules allows individuals to offer "for sale" equipment, but those offering commercial services are limited to once a month. I think that is adequate to "get the word out" without disrupting the list. If you have read this far, I would encourage you to add "OT" to the subject line if you make a post that is really off-topic - even if you are replying to another post. 73, Don W3FPR 73, Don W3FPR On 5/28/2017 3:36 PM, Dauer, Edward wrote: -- I believe both kinds of views are valid, this coming from a confessed but unabashed occasional OT-committer.

Re: [Elecraft] KXPD2 Paddle
Tom ... I feel your pain but not your conclusion. For me the post-loosening problem was solved with Loctite Blue. Since that didn't work for you, Loctite Red is the next logical step. If that doesn't work, JB Weld most certainly will. Just a drop of either adhesive coating the entire shank of the screw(s) will absolutely make that a permanent cure. Carefully done, the fix is invisible. Why Elecraft doesn't do it as a routine step in the manufacturing process I don't know. The KXPD2 is an excellent mini-paddle once the posts are permanently anchored. 73, Kent K9ZTV > On May 28, 2017, at 1:05 PM, Tom Francis, W1TEF wrote: > > Greetings, > > First, before I go any further, I have nothing but the highest regard for > Elecraft's Customer > Support and Service.

Re: [Elecraft] KX2/3 Amplifiers
When I priced them, the Hardrock was just about half the cost for half the power. I got the KXPA100. The KXPA100 kit is assembly, no soldering.

Re: [Elecraft] KX2/3 Amplifiers
Phil, The Hardrock 50 has an atu - I don't know if the toroids are pre-wound or not - if not, that's an issue for me. Actually, I'm kind of in the reverse situation - I want to keep my KX2/3, but get rid of my FT-450D - which is a nice radio, but it's bigger than I can use mobile. All suggestions are welcome and you certainly gave me something to think about. Thanks.

Re: [Elecraft] KPAIO3 modification - E740287
Hi Ron. Thanks for the confirmation. I figured out that Rev A was a mistake, after looking at the fan connector and fan supply orientation. Had Rev A been used it wouldn't have been a disaster, but the mod would have had no effect, as it connected both ends of the capacitor to the positive fan supply! Oops! I haven't seen any errata but it doesn't matter now. My KPAIO3 module isn't the same layout as the ones shown, but the actual connections are the same to the fans.

[Elecraft] KXPD2 Paddle
Greetings, First, before I go any further, I have nothing but the highest regard for Elecraft's Customer Support and Service. I've had several issues with my KX2 that were due to operator error and Elecraft has fixed my self-induced KX2 injuries quickly and efficiently. Plus, I've had a couple of other dealings with Customer Service all outstanding. However. ;-) I've been dealing with a KXPD2 paddle issue since I purchased my KX2 last year. I've gone through four of them all with the exact same problem. To wit: After use, say half hour or so, the contact posts loosen up and the CW becomes impossible. I've tried everything I know how to do - Loc-Tite blue goo, used a mini-torque wrench to set torque, pushed the envelope with tightening up the screws - the contact posts loosen up. I have a very light touch with my paddles with very close spacing as CW is my primary mode of choice for 54 years. So I don't think that its heavy tapping or wide spacing that is causing the problem. If I were to guess, I believe it is a dissimilar materials issue - metal screws, plastic base, warm radio causing the plastic to expand JUST THAT LITTLE BIT to loosen up the screws. Now here's the thing - four paddles all having the same issue on the same radio with the same operator seems to be indicative of a manufacturing problem. Maybe it is peculiar to me - I'm not discounting that, but it seems unusual. What I'm wondering is if anybody else who owns and uses these paddles have the same issue? Thanks.

[Elecraft] CP1 vs other directional coupler
I'd like to get a directional coupler to, among other things, monitor my transmit signal on a scope. The Elecraft CP1 kit is priced well, but I'd want it in a metal box with panel mount connectors, SO-239 for the main RF path. I'd also rather use 50 ohm terminators rather than switches, so at that point it probably makes sense to build my own. Just curious what others have done and if there are recommendations for reasonably priced, commercially available directional couplers for HF at 100 W or more.

Re: [Elecraft] [K3] RFI Problems - HELP!
Gray, Does your term "serial grnd" mean the RS-232 Signal Ground? If so, that should not be connected to the enclosure ground. As far as the K3 grnd goes, "bond" the K3 enclosure to the outside of your interface box, and then on to the computer - follow the audio and serial lines with the bonding. Bond the K3 also to your station ground. You might also want to add good current mode chokes to your feedlines. If your end-fed antenna is of the type which uses the coax shield as the 'counterpoise', then either add a wire counterpoise that is 0.05 wavelength long (at the lowest frequency of operation) at the junction of the radiator and coax and place the choke also at that junction - or - place the choke 0.05 wavelength from the junction. 73, Don W3FPR On 5/28/2017 11:50 AM, G Wood wrote: I decided to rebuild my CW/FSK/PTT interface, the old one was done for IC7000 with audio isolating trannies etc. The new circuit uses 3 opto-couplers, built in a small diecast box, at the moment the input serial grnd goes to input of opto's and the K3 grnd goes to output of opto's, the box is connected to station grnd.

[Elecraft] [K3] RFI Problems - HELP!
Hello All. My setup is, K3 (sn:5845), computer Athlon 2.5 GHz running WinXP, and homebrew logging program. Antennas, 40m e/f inv vee tuned through ATU on all bands, and 20/15m Bi-square coax fed into shack. Ground is 1/4 wave radials for each band, strapped together and connected to ATU, K3 grnd point and computer chassis. Recently I've been plagued with RFI? problems. I originally ran Win98se with very few problems. I upgraded to WinXp, so I could run SDR progs that wont run on 98se. This is when the problems started. I had to rehash logging prog to get K3 Cat working. things seemed OK. I was sending a rprt on 80m CW, when suddenly calculator, win media player and internet explorer started. I was running 100w, reducing to 60w seemed to clear the problem. I decided to rebuild my CW/FSK/PTT interface, the old one was done for IC7000 with audio isolating trannies etc. The new circuit uses 3 opto-couplers, built in a small diecast box, at the moment the input serial grnd goes to input of opto's and the K3 grnd goes to output of opto's, the box is connected to station grnd. Question: A) should the serial grnd go to the box. B) should the K3 grnd go to the box. C) or should they all be connected to the box. How does this affect the isolation of input/output of opto's? Recently keying the rig from the computer, the K3 would lock up, if I keyed using paddle and K3 keyer no problem also discovered turning off K3 port on computer(no CAT to K3), no other changes, keyed OK.

I can run 100w on all bands, with full Cat to K3, on dummy load. Everytime I try something new it gets worse, more questions than answers. I've hit a brick wall. I know I need to gradually take things a step at a time, the question of the interface box is a start point. I throw myself at the mercy of the reflector, hoping the guru's can provide an answer or at least point me in the right direction.

Re: [Elecraft] [K3S] JT65-HF Beginner
Big point. Once he releases the source code under GPL he has no recourse. These developers can take his source code, do exactly what they want to it, and don't even have to change the name of the application. If the program was written with GPL tools, compilers, libraries, dll's, etc..., as WSJT-X was, he is required to release the code. He can charge for bis version of the program and charge for support. He does have control over what makes it into his version. Other than that nope. It's about time Elecraft released their code under GPL so pimple faced kids living in Mom's basement with no visible means of support, can write "some really cool stuff" for the Elecraft products.

[Elecraft] KX3 alc/cmp and swr/rf display
Got two KX3 radios sitting here. Both in USB mode. On one, pressing the keyer/mic button switches the display between swr/rf and cmp/alc. On the other radio pressing keyer/mic it switches between showing mic gain and wpm in vfo b, but always shows cmp/alc. What are we missing? 73, -detrick KI4STU __ 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] [KX3] Legs
Yes Ingo, you can use two washers on each leg's thumb-screw with the leg sandwiched between the washers. At least this works for me. 73 Ken - K0PP On May 28, 2017 03:41, "Ingo Meyer, DK3RED" wrote: > Hello Elecrafters, > > > I have a little mechanical nuisance with the legs of my KX3. > > If I carefully tighten the screws, after a while the right leg can no > longer be folded out completely and the left leg wobbles. > > Is there a solution to hold the underside of the transceiver in place AND > to hold the legs, so i can move the legs evenly for a longer time? > > > 73/72 de Ingo, DK3RED - Don't forget: the fun is the power! > www.qrp4fun.de - dk3...@qrp4fun.de > __ > 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 kengk...@gmail.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] KPAIO3 modification - E740287
I'm in the process of upgrading our club's K3, new synth, DSP and a stack of small mods. I've come up against an issue that's causing me some confusion. The mod for the KPAIO3 consist of a small electrolytic capacitor soldered to two pins on the KPAIO3 module. I have two versions of instructions, one dated April 13 2016 - Revision A and the other dated August 10 2016 - Revision B. I presume that Rev B supersedes Rev A, so I should follow Rev B? The images on both sheets appear to show the KPAIO3A module, but describe the KPAIO3 module, so I presume for the purpose of modding they're the same, however the Negative lead of the new capacitor is shown going to different points on the module, depending which instruction sheet is viewed and looking at the trace layout on either, this doesn't make sense. Besides that, the trace layout on the module that I have is different to both of the paper descriptions. Can anyone shed any light on this conundrum or know if any addendum has been issued? 73, Alan.

Re: [Elecraft] [K3S] JT65-HF Beginner
I like WSJT-X but I use JTDX as much or more. It adds some interesting features to the decoding. WSJT-X interface is a little more polished but JTDX isn't bad. Read about different versions and try them out before discounting them because someone says so. 73, Kev K4VD On Sun, May 28, 2017 at 3:38 AM, Jim Brown wrote: > On Sun,5/28/2017 12:18 AM, Richard Lamont wrote: > >> I agree with all of that, except the 'unauthorized' bit. >> > > Joe has posted on that topic.

[Elecraft] KPA500 not working
Hi, My KPA500 started acting up and now does not amplify at all, and the input SWR seems to bounce around. I did hear what sounded like an arc (fairly loud bang, though it was the KAT500, not the KPA500) The KAT500 is still working normal, but the KPA500 is bad, even into a dummy load with the KAT500 bypassed. Any ideas? or just get an RMA and send it in?

[Elecraft] [KX3] Legs
Hello Elecrafters, I have a little mechanical nuisance with the legs of my KX3. If I carefully tighten the screws, after a while the right leg can no longer be folded out completely and the left leg wobbles. Is there a solution to hold the underside of the transceiver in place AND to hold the legs, so i can move the legs evenly for a longer time? 73/72 de Ingo, DK3RED - Don't forget: the fun is the power! www.qrp4fun.de - dk3...@qrp4fun.de __ 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

All the derivatives are authorized by K1JT's decision to release his source code under the GNU General Public License (GPL). His intention in doing so was presumably to attract developers to the project rather than facilitate a plethora of half-baked forks. These 'me too' knock-offs contain typically 99% source code from WSJT-X. They variously offer (1) a reduced subset of functionality, (2) 'deep decode' at the cost of more frequent erroneous decodes, (3) inappropriate use of VHF-only features on HF, and (4) balkanized on-air protocols with badly-thought-out and incompatible modifications. As Jim said, you should ONLY use WSJT-X. It is developed by a team of very clever people. It's also worth following wsjtgr...@yahoogroups.com - it's an excellent forum/list with frequent posts from the lead developers. 73, Richard G4DYA __ 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
