[Elecraft] Elecraft CW Net Announcement
Good Evening, It was a good week. I felt like the snail on the side of a well though. Some successes, some failures but I am still on the side of the well. I wonder what the snail feels like when he reaches the top and starts down the outside? There was some sun shining into my well. Above freezing with little rain. However, sometime tonight the snow starts falling. By Wednesday there should be more than enough to cause problems. The sun is more active than last week. Three small sunspot groups now with more over the limb. A stream of solar wind is due on the 25th. For now the bands should be quiet with medium levels of QSB. Neither of my antennas was hit by flying limbs. There are fewer weak limbs remaining after the thinning. I hiked the property a few days ago and found the smaller diameter slash is mulching nicely. The alders are self thinning which provides good sleeping areas for the elk and deer. The grouse are in a down cycle, I did not flush any of them. Please join us tomorrow on: 14050 kHz at 2200z Sunday (2 PM PST Sunday) 7047 kHz at z Monday (4 PM PST Sunday) 73, Kevin.

Re: [Elecraft] Mac vs K3s - Redux
Try shortening your poll rate if you can, to maybe 500ms. I realize in some cases that might be too fast for the K3, but play with that. Also, serial ports are typically these days “eight, one, none.” I see you have “eight, TWO, none.” Make sure your port is really configured that way. Unless you explicitly set it for two stop bits, it’s likely defaulted to eight, ONE, none. One stop bit is generally quite adequate. 73, David - N5DCH > On Jan 23, 2021, at 5:23 PM, Richard wrote: > > Well, here’s where we are.

[Elecraft] Mac vs K3s - Redux
Well, here’s where we are. I’ve downloaded a new FTDI driver, but am holding off on installing it as a last resort. Operationwise, I’ve whittled down to size most of the problems, but the transmit timing is still not wonderful. It starts transmitting within a second or two of when it should, like at :17 instead of :15. I can live with that for the moment. Coming OUT of transmit is something else. Sometimes it stops right on the button just like it should and lulls me into thinking everything’s OK. But then, erratically and with no apparent pattern of occurrence, WSJT will come out of transmit but the radio is STILL transmitting! Sometimes for several seconds before quitting, sometimes I have to stop it manually. This ain’t no way to run a railroad! My RADIO panel settings are: K3s Poll 1 s /dev/tty.usbserial-A6009F3,38400 Eight Two None No DTR or RTS settings CAT Data/Pkt None. Any and all ideas will be most welcome. Cheers!

Re: [Elecraft] REMOTE OPERATION
Paul, I attended the "Demo" meeting last night and was told that Elecraft will release remoting software so you don't have to have a K4/0, HOWEVER, the further nuance to your question is probably "Can I use a paddle to send CW?" That was not directly discussed but I'll bet the answer is no. I'm sure you could use a keyboard to send CW but I'm not sure that capability will be built into Elecraft's remoting software. For my own interim remote setup (I'm waiting on the K4/0), I found a client server application (df3cb.com) that uses a WinKeyer to give you paddle CW. It requires a WinKeyer on BOTH ends of your remote. The idea is that you are paddling your local WinKeyer and it is talking to the remote WinKeyer which is connected to your remote rig. That same remote capability is built into a WinKeyer (https://www.hamcrafters2.com/files/WKremote.pdf) and called WKremote by K1EL. I didn't use that because I have a YCCC SO2R Box (which emulates a WinKeyer V1, I think) at my station so since I didn't have two WinKeyers, I tried the DF3CB idea and it worked! You need to turn off the sidetone monitor on your rig and use the sidetone of your local WinKeyer but it works fine when you want to use a paddle for remote CW.

Re: [Elecraft] Mac vs K3s - Again
If you have a 3rd party FTDI driver installed, that may be part of the problem. MacOS has had FTDI drivers since at least 10.12. I also would seriously suggest updating to at least the last update of 10.13; 10.14 would be better. 73, Chuck, AA3CS — Engineer: "If it ain't broke I haven't messed with it enough yet."

Re: [Elecraft] Mac vs K3s - Again
Given that you are running generally older hardware and system software, you probably don'tneed to worry about how "out of date" your FTDI driver might be. (I'm running a 2017 iMac withBig Sur installed and working beautifully). I assume that your USB hardware really is FTDI andnot one of the infamous clones that have been discussed to death here and in other forums.If it really is FTDI, then D2XX Drivers - FTDI lists version 1.4.22 as having been released on21 January 2021 (!) and is suitable for Mac OS X 10.4 Tiger or later, which should be OK for you. | | | | D2XX Drivers - FTDI | | | HTH and 73, Brandy, N1HO On Saturday, January 23, 2021, 11:51:23 AM EST, Richard wrote: Working hard to wean my K3s off a SignaLink and connect it directly via a standard A/B USB cable.

(lightning doesn't see my antennas any more than the coffee cup in my hand)? Keep in mind that I live on the ridge in south central Florida running down the center of the state from Lake Wales to the north and sloping to the south into the Everglades. (From Tampa to here is the lightning capital of the western hemisphere) We are second in the world to a location in south eastern Africa for lightning strikes. In the 25 years I have lived here we have had several hams get hit by lightning that followed code to a "T" including a perimeter wire completely surrounding their home and tied to the main electrical ground, towers, polyphasers and or lightning arrestors bounded to at least 10 foot rods going into our sandy soil.?? In the most recent hit, a good friend and local ham in Lake Placid had his home burn completely to the ground, with his wife just narrowly escaping the inferno. He had everything grounded correctly including a 4 gauge perimeter wire completely surrounding his home. John's 120 foot tower was not hit and his coax cables and pl259/s were not scorched.? In his case the lightning hit the Duke power company line coming into his home and exploded into his house with a massive hole, and according to the state inspector it was textbook 101, blowing through all electrical outlets in his home at the same time. His wife had less then 30 seconds to get out. By the way, John KK4LI, installs towers, and antennas for a living. He also conducts classes on lightning protection at the Tampa hamfest.??

[Elecraft] lightning protection
In addition to everything else suggested, I disconnect all coax cables outside my home and let them lay on the ground. I use a trailer type connector to unplug my antenna rotator. I further use a heavy duty DPDT switch for my full wave 80 meter loop, not to ground but to open. (lightning doesn't see my antennas any more than the coffee cup in my hand) Keep in mind that I live on the ridge in south central Florida running down the center of the state from Lake Wales to the north and sloping to the south into the Everglades. (From Tampa to here is the lightning capital of the western hemisphere) We are second in the world to a location in south eastern Africa for lightning strikes. In the 25 years I have lived here we have had several hams get hit by lightning that followed code to a "T" including a perimeter wire completely surrounding their home and tied to the main electrical ground, towers, polyphasers and or lightning arrestors bounded to at least 10 foot rods going into our sandy soil. In the most recent hit, a good friend and local ham in Lake Placid had his home burn completely to the ground, with his wife just narrowly escaping the inferno. He had everything grounded correctly including a 4 gauge perimeter wire completely surrounding his home. John's 120 foot tower was not hit and his coax cables and pl259/s were not scorched. In his case the lightning hit the Duke power company line coming into his home and exploded into his house with a massive hole, and according to the state inspector it was textbook 101, blowing through all electrical outlets in his home at the same time. His wife had less then 30 seconds to get out. By the way, John KK4LI, installs towers, and antennas for a living. He also conducts classes on lightning protection at the Tampa hamfest. Of further interest, our number one item for getting hit in our area seems to be Dish and Direct satellite dishes.

Re: [Elecraft] K3: CW characters sound very hard / short
Yes, this is the answer. The original KSYN boards didn't have a powerful enough processor for high speed CW. My K3 works just fine for my weekly QRQ sked at about 60 WPM, and at least one other in the group runs a K3.

Re: [Elecraft] Automatic lightning protection for radios
We had a direct strike a few years back, and the results were interesting. In most cases a gap of an inch or less vs. a direct connection made a huge difference. The lightning took the easiest path to ground every time. But that's the key ... you can't just "open" the line, it needs to be switched to a ground connection.

Re: [Elecraft] K3: CW characters sound very hard / short
Put KSYN3A Synthesizer Upgrade Boards into your K3 and CW Chars are ok at QRQ high speed Have done this mode on my K3 and got an completly another Radio also on receive 73 Oe6kyg -Ursprüngliche Nachricht- Von: elecraft-boun...@mailman.qth.net Im Auftrag von dl2ki Gesendet: Freitag, 22. Jänner 2021 07:23 An: elecraft@mailman.qth.net Betreff: [Elecraft] K3: CW characters sound very hard / short Hi, a friend tells me that the CW characters sound very hard / short on his K3 in the standard mode "CW QRQ = OFF". This makes the characters at higher speed ~50WPM vy hardly readable by the QSO partner. Experiments with "CW WGHT" do not lead to success. At higher speeds, my friend therefore switches to the mode "CW QRQ = On", where the effect does not occur. However, some functions (RIT, SPLIT) are unfortunately not available there. Therefore, this is not an ideal solution. So far I have not found any clues to help him solve the problem. Are there other setting possibilities to solve this issue, or can there also be a hardware problem here? 73, Wolfgang DL2KI -- 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 k...@ccf.net __ 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] K3: CW characters sound very hard / short
Hi Andrew, Pete and Dave, thank you very much for your feedback. Yes, when searching the mailing list, it depends a lot on the search terms. So sometimes the search is a bit difficult. I will therefore continue to search with other terms. The issue occurs with the K3 internal keyer and is already audible even at speeds below 50 WPM. The use of an external keyer would be a solution, but since the effect does not occur with my K3, for example, the sound of the CW characters should actually be equally good with all K3's. Already experimented with different menu parameters. "TX DLY" is set to "008". But on the basic problem this had so far no influence. I have therefore rather the assumption that here somewhere a hardware problem is present with this special K3. 73, Wolfgang Dl2KI -- 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
